Wear-resistant flooring market situation of foreign

Inorganic Materials Floor

50's of last century, due to the impact of the third industrial revolution, synthetic techniques, electronics, industrial automation, new materials, new energy and aerospace industries have been the areas of innovation and development, Western Europe and Japan's economy has to grow up quickly . In this case, some of the major manufacturers of materials such as West (SIKA), Meister MBT (Degussa's are attributed), ABC Co., Ltd. of Japan, the rich Salong (FOSROC) and so on all the ground with cement-based concrete wear-resistant material types of products available, and the product is widely used in industrial plant construction.

70 to the 20th century, as Japan's labor tensions and the high cost of self-leveling cement-based materials first developed in 1982 began to cement-based self-leveling floor materials, and because of its wide use, dosage, quality and stability, the market has been rapid development and wide acceptance, and other developed countries have also introduced a variety of brands of cement-based self-leveling floor materials, especially in Europe and America as represented by the countries and regions, mainly in pursuit of its functionality and durability , more is the main cement-based self-leveling.

Tuan 1972, the first Japanese domestic public research on gypsum-based materials, and in 1976 on the use of α-hemihydrate gypsum plaster to the substrate ground-based self-leveling the construction materials testing, 1977, a small amount of gypsum-based products began to use self-leveling in the business. In recent years, due to hardening of gypsum-based screeds in the deformation process does not produce, you can have a good mechanical laying operations and ease of mobility, seamless and easy to cast a large area, with a good economy, and other fine features are perceived the industry. Gypsum-based self-leveling on the market the main raw material is anhydrite II and α-hemihydrate gypsum, Germany, Pa EI-Royce with type II anhydrite, Qi Luoni companies with α-hemihydrate gypsum are produced strength to 20 ~ 30MPa, the laying of 10mm thick plaster-based self-leveling flooring material. The United States developed the α, β-gypsum mixture by adding at the scene after the pumping aggregate self-leveling floor plaster-based materials have been widely used.

Europe has been classified as self-leveling floor materials to the new standards set mortar floor (ENDIN13813-2002). European Association for Standardization (CEN) have been developed or are developing a series of ground materials and products and their performance screed test methods. There have been published EN13318-2000 "leveling the ground floor leveling materials and definition of terms", EN13409-2002 "self-leveling mortar ground with initial setting time of the determination of test methods", ENDIN13813-2002 "leveling material and ground leveling screeds Properties and requirements ", and other European standards. Also developed a "wear and tear as the industrial and commercial polymer modified cement base level of surface material and construction specifications Guide" to guide material selection and design, construction and acceptance. Being drafted with PrEN1937 "the ground with the standard test methods for self-leveling mortar mixing procedures," "ground-test method with self-leveling mortar flexural and compressive strength determination," "ground-test method with self-leveling mortar fluidity determination "and other European standards.

Asia-Pacific countries and regions represented, because of effect, to flooring materials are mostly organic, but the Japanese because of its small population, the high cost of labor tension and, for the self-leveling cement-based product development earlier. South Korea also conducted a self-leveling mortar on the ground research, production and application, and in 2001 worked out a KSF4041: 2001 "self-leveling cement-based mortar," the national standard to regulate the production of their products.

Floor organic material

Organic types of floor materials is roughly the current epoxy, polyurethane, acrylic acid (crosslinked), polyurea flooring materials. With the latex material on the mid-century emergence of the coatings industry has made some progress, but that time is also mainly used for interior and exterior paint and roof decoration. Began in the late last century in Europe and America there have been many clean workshop floor, it uses the whole polymer surface layer, known as the "epoxy floor paint" (epoxyflooring), mainly composed of epoxy resin and curing agent and epoxy membrane material made of resin as the main floor of the organic material began to be developed, particularly in the industrialized development of internationally developed earlier, such as Western Europe, Japan and other countries have six or seven years of history, as applied to the first ping of the resin material, the proportion of the most mature technology is also the largest species, according to the Japanese Association from 1993-2006 painted floor, the floor space on the Japan market research reports on material shows that the application of epoxy floor has accounted for dominance of the total amount of 45.6%. Since solvent-based epoxy floor coating in the production, construction and curing process will emit a certain amount of volatile organic compounds (VOC); but no epoxy floor coatings are more environmentally friendly solvents, no volatile organic compound emissions, so foreign to non- solvent-based, small to use water-based systems, solvent-based systems are very few materials, most materials, solvent-based company has not produced material.

Polyurethane epoxy material relatively late, in 1965, the British company Imperial Chemical Industries (ICI) to Otto. Bayer (OttoBayer) polyurethane raw materials for the substrate Mr. developed the first polyurethane flooring products. Subsequent years, the main floor business in Europe and America have launched a polyurethane flooring products, which typically include: Swiss Sika (Sika), Conica, the German Meister (MBT), the UK Department of Hang (Flowcrete) , Sweden Bo Shide (Perstorp), the United States Sherwin (Sherwin-Williams), Stonhard and the ICS and other companies. NPU also always of the total amount of about 20%. Polyurethane flooring products and construction technology for its manufacturing technology is relatively difficult to control, but more common epoxy floor has a higher impact resistance, wear resistance, organic acids, high temperature, UV ultraviolet radiation and chemical corrosion, . The performance of a wide range of adjustable, flexible epoxy body have a similar hardness, resistance to organic acids and organic solvents is better than epoxy, epoxy incomparable more flexibility. In machinery manufacturing, food processing industries gained more and more widely used. Foreign materials such as polyurethane epoxy floor, as a non-solvent system based, small water systems.

To the mid-eighties of last century Texaco (now the Huntsman) in the reaction injection molding (RIM) technology, successfully developed on the basis of the first spray polyurea elastomer (SPUA) technology, which is the second high-solids coatings, waterborne coatings, radiation curable coatings, powder coatings, such as low (no) contamination after coating technology, to meet the environmental needs of research and development of a new solvent-free, pollution-free green construction technology, it inherits the RIM technology, impact mixing principle, but a breakthrough the limitations of the mold must be used RIM will instantly cure, high-speed response characteristics to a whole new area of ​​expansion has greatly enriched the scope of application of polyurethane to broaden the awareness of paint, coating technology concept. In 1991 the technology into commercial applications in North America, after the development has been rapid, Australia, Japan and South Korea in 1993,1995 and 1997 respectively, the introduction of the technology, and have been put into commercial applications, is currently the largest global polyurea Consumption in the United States (85%), followed by Asia (10%) and Europe (4%). In 2000, the United States set up a "Polyurea Development Association" (PolyureaDevelopmentAssociation referred to as PDA), to further standardize the market, and promote the harmonious development of technology in the United States.
