Hydrogenated petroleum resin containing hydroxyl

Japan Arakawa chemical industry company has successfully developed a hydrogenated petroleum resin with 1 ~ 2 hydroxyl groups in its molecule. Due to the role of hydroxyl in the resin, it can be used as a tackifier of acrylic adhesives and a modifier of polyolefins

this hydrogenated petroleum resin is an amorphous oligomeric resin with a relative molecular weight of hundreds to thousands. Due to hydrogenation, it has the stability of hue, smell, heat and light. Therefore, it can be used as a tackifier for adhesives and plastic additives. Remove the broken test piece and tightly align the broken test piece to the same agent. The hydrogenated petroleum resin containing hydroxyl group is successfully developed by using the technology of introducing hydroxyl group into the double bond of petroleum resin and the technology of selective partial hydrogenation. It also has the functions of automatic algorithm generation and automatic experimental report; It greatly facilitates the debugging and system redevelopment capabilities. At present, the company is developing kr-1840 with low melting point (90 ℃) and kr-1842 with high boiling point (120 ℃)

hydrogenated petroleum resins containing hydroxyl groups are expected to be used as modifiers for polyolefins. Polyolefin has the disadvantages of poor printability and adhesion. It usually needs corona treatment, surface modification or chlorinated polypropylene as anchoring agent to fix the ink on the coating and coating layer. Kr-1840 series has good compatibility with polyolefins. The value displayed on the polyolefin computer is the average value of this experiment group. Add 10% - 15% to the hydrocarbon. After mixing, avoid dust falling into the machine, and hydroxyl groups are exposed on the polyolefin surface, so that the surface modification can improve the adhesion of polyolefins and the coating property of inks. In addition, hydrogenated petroleum resin containing hydroxyl can also be used to react with special diols to produce polyurethane or polyester
