C9 Petroleum Resin Usage
Petroleum resin is different from general resins and cannot be used alone. It is usually blended with other substances to improve the performance of various products.
Petroleum resins are mainly used in the following areas:
(1) Application in the paint industry. In the coating industry, petroleum resin can be combined with other resins to completely or partially replace high-value resins, thereby achieving the goal of reducing costs, improving the luster, hardness, water resistance, stability, and chemical resistance of products. If C9 petroleum resin is used in the formulation of phenolic varnish to replace rosin modified phenolic resin and rosin calcium resin in equal quantities, the resulting product still meets the standards of phenolic varnish and phenolic enamel. However, the cost of C9 petroleum resin is less than 1/4 of that of rosin modified phenolic resin, which can greatly reduce costs. Adding alicyclic petroleum resin to epoxy resin and polyurethane blended paint can improve the hardness, bending test, temperature water resistance, weather resistance, and other indicators of the product.
(2) Application in adhesives. In adhesives, petroleum resin mainly plays a role in providing adhesion. The main components of adhesive are basic polymers such as natural rubber, synthetic rubber, polyolefin, polyacrylic acid vinegar, ethylene vinyl acetate copolymer, etc. The addition of petroleum resin can improve the bonding stability, creep resistance, heat resistance, and other properties of these polymers. If petroleum resin and SBS thermoplastic elastomer block copolymer are mixed in a mixed solvent of toluene hexane, the resulting viscous mixture can be used to prepare pressure sensitive adhesive tapes as pressure sensitive adhesives.
(3) Application in the rubber industry. C9 petroleum resin is mainly used as a softening additive in the rubber industry. The styrene butadiene rubber itself lacks viscosity and is hard. Adding C9 petroleum resin causes the molecular chains of styrene butadiene rubber to be divided, resulting in a good viscosity and softness of the product. On the other hand, C9 petroleum resin can reduce the amount of natural rubber to synthetic rubber, significantly reducing costs without changing the quality of rubber products. In terms of technology, the use of petroleum resin can save a raw rubber refining process, shorten the production cycle, and improve economic benefits.
(4) Application in printing ink. In ink, petroleum resin is mainly used as a connecting material. Petroleum resin has good compatibility with many components in ink, and for various specifications of printing ink, there are corresponding petroleum resins to meet the requirements of various indicators such as wetting speed, drying speed, solvent release, water and alkali resistance. Petroleum resin is processed into ink, which can maintain a stable dispersion state of pigments for a long time
