Application of petroleum resin in various fields:
Hot melt adhesive
Other applications: hot melt pressure sensitive adhesive, solvent pressure sensitive adhesive.
The performance and role of petroleum resin in different industries:
The paint mainly uses high softening point C9 petroleum resin, DCPD resin, C5/C9 copolymer resin. The addition of petroleum resin to the paint can increase the gloss of the paint and improve the adhesion, hardness, acid resistance and alkali resistance of the paint film.
The rubber mainly uses low softening point C5 petroleum resin, C5/C9 copolymer resin and DCPD resin. This kind of resin has good mutual solubility with natural rubber colloidal particles, and has no great influence on the rubber vulcanization process. The addition of petroleum resin to the rubber can play a role in thickening, strengthening 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 cords. It is suitable for high-demand rubber products such as radial tires.
C. Adhesive industry
Petroleum resin has good adhesion. Adding petroleum resin to the adhesive and pressure-sensitive tape can improve the adhesive strength, acid resistance, alkali resistance and water resistance of the adhesive, and can effectively reduce production costs.
D. Ink industry
Petroleum resins for inks 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. Coating industry
Road marking and road marking paint, petroleum resin has good adhesion to concrete or asphalt pavement, and has good wear resistance and water resistance, good affinity with inorganic substances, easy to apply, 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 mainstream, and the demand is increasing year by year.
The resin has a certain degree of unsaturation and can be used for paper sizing agents, plastic modifiers, etc.
