Application of Hydrocarbon Resin
Performance and role of petroleum resin in different industries:
A. Paint and paint mainly use high softening point C9 petroleum resin, DCPD resin, C5/C9 copolymer resin, paint added to petroleum resin can increase paint gloss, improve paint film adhesion, hardness, acid resistance, alkali resistance.
B. Rubber rubber mainly uses C5 petroleum resin, C5/C9 copolymer resin and DCPD resin with low softening point. Such resin and natural rubber particles have good miscibility, there is no great effect on the rubber vulcanization process, rubber added petroleum resin can play a role in viscosity, reinforcement and softening. 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 cord wire, which is suitable for high-demand rubber products such as radial tires.
C. Adhesive industry petroleum resin has good adhesion, adding petroleum resin to adhesive and pressure-sensitive tape can improve the adhesion of the adhesive, acid resistance, alkali resistance and water resistance, and can effectively reduce the production into Chemicalbook.
D. Petroleum resin for ink in ink industry, mainly high softening point C9 petroleum resin, DCPD resin. The addition of petroleum resin to the ink can play a role in color spreading, fast drying, brightening, and improving printing performance.
E. Coating industry road signs and road marking coatings, petroleum resin has good adhesion to concrete or asphalt pavement, and good wear resistance and water resistance, and inorganic substances have good affinity, easy coating, good weather resistance, fast drying, high firmness, and can improve the physical and chemical properties of the layer, improve ultraviolet resistance and weather resistance. At present, petroleum resin road marking paint is gradually becoming mainstream, and the demand is increasing year by year.
F. Other resins have certain unsaturation and can be used for paper gluing agents, plastic modifiers, etc.
