Three major breakthroughs are urgently needed and currently underway in China's epoxy resin for infrastructure construction
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

The properties and corresponding uses of C5 Hydrocarbon resin
What are the functions of Hydrocarbon resinsLow temperature function. Together, it has anti water function. Commonly used for bonding plywood, wallpaper, and leather.Forming function to prevent problems such as delamination and bubbles. Mainly used for producing tires, V-belts, and rubber hoses.Rubber processing: used as a thickening agent in rubber processing. It can play a role in softening, strengthening, and increasing viscosity, thereby improving processingAdhesive production: Used in adhesives, especially hot melt adhesives and pressure-sensitive adhesives, it can significantly enhance their viscosity, elasticity, andCoating production: commonly used in the manufacturing of reinforced latex coatings, it can also be used to produce oil soluble coatings, effectively improving the gloss, hardness, waterproofing, and chemical resistance of coatings. Plays a role in high surface hardness, good gloss, and fast drying speed.Paper industry: used as a sizing agent for paper. Compared with traditional rosin, it has fewer bubbles, smoother paper surface, and can reduce the absorption of water and ink, which is beneficial for improving the smoothness, hydrophobicity, and printability of the paper.Ink production: It can dissolve in hydrocarbon resins, has a high softening point, and is functionally stable, making it suitable for the production of printing ink. Adding Hydrocarbon resin to ink can play a role in color development, quick drying, brightening, and improving printing function.Other uses: In oilfield chemistry, it can be used as an oilfield water treatment agent, drilling mud additive, and also as an asphalt modifier.Puyang Shenghong Chemical Co., Ltd. focuses on DETDA, Hydrocarbon resin, polyurethane resin, polyurethane adhesive, and curing agent work, serving global coatings, adhesives, and packaging work.The above content is sourced from the official website of Shenghong Chemical Industry in Puyang City: www.shenghongchem.cn

The performance and function of carbon nine Hydrocarbon resin
A. Rubber: Rubber primarily uses low softening point C5 Hydrocarbon resin, C5/C9 copolymer resin, and DCPD resin. This type of resin has good compatibility with natural rubber particles and does not have a significant impact on the vulcanization process of rubber. Adding Hydrocarbon resin to rubber can have the effect of increasing viscosity, strengthening, and softening. Especially with the participation of C5/C9 copolymer resin, not only can the adhesion between rubber particles be increased, but also the adhesion between rubber particles and cord can be improved, making it suitable for high demand rubber products such as radial tires.B. Paint: Paint mainly uses high softening point C9 Hydrocarbon resin, DCPD resin, C5/C9 copolymer resin. Adding Hydrocarbon resin to paint can increase the glossiness of the paint, improve the adhesion, hardness, acid and alkali resistance of the paint film.C. Adhesive profession: Hydrocarbon resin has good adhesive properties. Adding Hydrocarbon resin to adhesives and pressure-sensitive tapes can improve the adhesive strength, acid resistance, alkali resistance, and water resistance of adhesives, and can effectively reduce production costs.D. Ink profession: Hydrocarbon resin is used for ink, mainly high softening point C9 Hydrocarbon resin and DCPD resin. Adding Hydrocarbon resin to ink can have effects such as color spreading, quick drying, and brightening, as well as improving printing functionality.E. Other: Resin has a certain degree of unsaturation and can be used as a paper adhesive, plastic modifier, etcPuyang Shenghong Chemical Co., Ltd. is dedicated to the professions of Hydrocarbon resin, polyurethane resin, polyurethane adhesive, and curing agent, serving the global industries of coatings, adhesives, and packaging.The above content is sourced from the official website of Puyang Shenghong Chemical: www.shenghongchem.cn
