"2022-2028 China C9 Petroleum Resin Market Survey and Market Prospect Forecast Report" consists of twelve chapters. Firstly, it introduces the market development environment of C9 petroleum resin industry, the overall operation situation of C9 petroleum resin, etc., then analyzes the current situation of C9 petroleum resin industry market operation, and then introduces the market competition pattern of C9 petroleum resin.   C9 petroleum resin is a thermoplastic resin obtained by polymerization of C9 fraction, a by-product of cracking to ethylene plant, as the main raw material, polymerized in the presence of a catalyst, or copolymerized with aldehydes, aromatic hydrocarbons and terpenes. Its molecular mass is generally less than 2 000, its softening point is less than 150 °C, and it is a thermoplastic viscous liquid or solid. Due to its low softening point and relatively small molecular weight, it is generally not used as a material alone.   Because the structure of C9 petroleum resin does not contain polar groups, it has good water resistance, acid and alkali resistance, weather resistance and light aging resistance, good solubility in organic solvents, and good compatibility with other resins. It also has brittleness, tackifying, cohesiveness and plasticity, and is mainly used in coatings, rubber additives, paper additives, inks and adhesives and other fields, and the market demand is large.

(1) Reinforcement: The tear strength of the compound reinforced with silica can be significantly improved. Therefore, about 10-25 parts of silica are usually added to the tread compound of many large-sized tires, which can significantly improve the tire tread. excellent resistance to cutting chipping. It should be noted that when using white carbon black to improve the tear strength of rubber products, with the increase of the amount of white carbon black, the wear resistance of the rubber compound will decrease, and the amount of white carbon black should be reasonably controlled.   (2) Adhesion: The surface of silica has active silanols, which is an important part of the adhesion system of m-methyl white. In actual production, the meta-naphthalene adhesive system can significantly improve the adhesive strength between rubber and skeleton materials (including cotton, nylon, polyester, steel wire, etc.).   ZC140 Powder Precipitated Silica for Rubber ZC140P Silicon Dioxide possesses a high reinforcing potential and imparts rubber compounds as the lower specific surface.

Hydrogenated petroleum resin Generally C5 or C9 petroleum resin is reddish-brown to light yellow, and can become white or transparent after hydrogenation. In the application of hot melt adhesives and adhesive tapes, the transparency of the resin is very important. Hydrogenation can also improve adhesion, weather resistance, stability and compatibility. C5 hydrogenated petroleum resin is made from the C5 resin fraction cracked by ethylene as raw material, and is obtained by cationic polymerization of diene and monoene in the C5 resin component. C9 Hydrogenated Petroleum Resin is a low molecular weight semi-hydrogenated water-white thermoplastic resin derived from chemical raw materials. In view of good heat resistance, good compatibility with EVA, SBC and other polymers, it also has good thermal stability and very low odor. DCPD hydrogenated petroleum resin is mainly composed of dicyclopentadiene and other low-molecular-weight polymers generated by polymerization under certain temperature and pressure conditions through a special process.

As an inorganic non-metallic material, glass fiber has good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is often used as a reinforcing material in composite materials, electrical insulation material and thermal insulation material. However, the surface of glass fiber is very polar, and it is difficult to be compatible with non-polar resin, which greatly reduces its filling effect. In order to improve the adhesion between resin and glass fiber and improve the strength, water resistance, electrical and weather resistance of glass fiber reinforced composites, it is necessary to modify the surface of glass fiber. At present, the most commonly used surface modifier in the surface modification of glass fiber is silane coupling agent, and its varieties mainly include: vinyl silane, amino silane, methacryloxy silane, etc.   Vinyl Silane Coupling Agent Crosile in Paint Adhesive and Fiber Glass Amino Silane Coupling Agent Crosile in Adhesive Fiber Glass and Rubber Silane Coupling Agent Crosile570 3-Methacryloxypropyltrimethoxysilane    

The performance and function of petroleum resin in different industries:   A. The paint mainly uses C9 petroleum resin, DCPD resin and C5/C9 copolymer resin with high softening point. Adding petroleum resin to the paint can increase the gloss of the paint, improve the adhesion, hardness, acid resistance and alkali resistance of the paint film.   B. Rubber mainly uses C5 petroleum resin, C5/C9 copolymer resin and DCPD resin with low softening point. Such resins have good mutual solubility with natural rubber particles, and have no great influence on the vulcanization process of rubber. Adding petroleum resin to rubber can increase viscosity, strengthen and soften. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesion between rubber particles, but also improve the adhesion between rubber particles and cords. It is suitable for rubber products with high requirements such as radial tires.   C. The petroleum resin in the adhesive industry has good adhesion. Adding petroleum resin to the adhesive and pressure-sensitive tape can improve the adhesive force, acid resistance, alkali resistance and water resistance of the adhesive, and can Effectively reduce production costs.   D. Petroleum resins for inks in the ink industry are mainly high softening point C9 petroleum resins and DCPD resins. The addition of petroleum resin to the ink can play the role of color development, quick drying, brightening, and improve printing performance.   E. Coatings for road signs and road markings in the coating industry, petroleum resin has good adhesion to concrete or asphalt pavement, and has good wear resistance and water resistance, and has good affinity with inorganic substances, easy to coat, good weather resistance, fast drying, high firmness, and can improve the physical and chemical properties of the layer, improve UV resistance and weather resistance. At present, petroleum resin road marking paint is gradually becoming the mainstream, and the demand is increasing year by year.   F. Other resins have certain unsaturation and can be used as paper sizing agent, plastic modifier, etc.
