Epoxy resin is a paving material.

China has a large market for epoxy resin flooring in the world, but it has not achieved a good global market for floor paving. Indoor flooring is a super large user of China's epoxy industry, accounting for more than 25% of the total epoxy usage in chemical building materials, exceeding 96000 tons, accounting for 68% of the entire paving material market. The entire paving material market accounts for 44% of the epoxy usage, reaching 130800 tons. It is predicted that in five years, In the entire epoxy building paving, the use of epoxy will reach 974000 tons, with epoxy flooring accounting for 10% of the total, slightly increasing from 98000 tons. However, epoxy asphalt, epoxy "sandwich" process paving, color paving, and reinforced protective agents for structural cement concrete jointly account for 35% of the total epoxy usage, reaching 342000 tons. Among the 244000 tons of paving materials, 200000 tons will replace imports and add new shares. China's self-produced and Self use materials currently account for no more than 60% of the total, and asphalt paving and composite structures account for no more than 5%, which requires us to break through.

The second is epoxy adhesive for the construction and repair of seams, patterns, and pores.

From the growth and development of a beautiful seam adhesive in recent years, people have seen the huge wave that epoxy adhesive has caused in the field of seam construction. Most people have not yet seen it. In the construction project of our entire infrastructure project, one of the main tasks is to build joints, expansion joints, beautify sealed joints, and connect stress absorption joints, but more is still the sealing, repair, waterproofing, anti-seepage, and crack resistance in maintenance work, A beauty sealant that disrupts the nerves of the industry is only a small variety that accounts for less than 1% of the total amount in construction gaps. Epoxy is used in construction projects for joint construction, joint repair, and crack prevention, accounting for more than 25% of the total usage. In five years, it will reach over 240000 tons. Joint repair, joint repair, and joint construction are major topics in the epoxy industry for building chemical adhesives, and should be included in our research and development applications.

The third is epoxy building structural adhesive. With highways, bridges, airport runways, high-speed trains, dams, docks, high-rise buildings, etc. Improving the operational quality and prolonging the service life of buildings requires not only the construction of new chemical building materials, but also those with low design standards. In order to improve the service life of roads, bridges, and airport runways that have been in operation for many years, epoxy structural adhesive in chemical building materials must be put on the top priority of core materials. The modification of cement, asphalt concrete, epoxy modified emulsified asphalt and other hydrophilic epoxy special adhesives will also be the main development materials for a long period of time in the future.

Polymer polymer mortar such as epoxy resin, and multifunctional active epoxy diluent used for strengthening cement concrete with hydrophilic epoxy resin, still have a significant gap in China's domestic research and development, production, and application compared to the international advanced level. However, the rigid demand must be localized, and we cannot let Huawei and ZTE incidents repeat in China's * * * * advantageous infrastructure projects. Once mistakes are made, it is a mistake of losing the party, the country, and harming the people. Five years later, according to the current maintenance and construction demand of building stock, building structural adhesive accounts for 40% of the total usage of epoxy building materials adhesive, reaching 390600 tons. Among them, there are many high-quality and high-tech products in epoxy products, and some characteristic products are also listed as precision products recognized by relevant departments of the Chinese Academy of Sciences
