Simultaneously, trimethylolpropane triacrylate is added to increase the entanglement between molecular chains, and calcium lignosulfonate and carboxylated butadiene-acrylonitrile latex are added to dissipate impact energy and inhibit crack propagation. Therefore, the resulting polyethylene liquid bag film also exhibits significant impact resistance.

PendingCN122648004APolymer scienceMeth-
The application discloses a PBT car lamp electroplating primer with anti-color fading performance and a preparation method and application thereof. The components of the primer include 20-30 parts of a cyclic structure polyol modified difunctional polyurethane acrylate resin, 8-15 parts of a ten-functional polyurethane acrylate resin, 5-10 parts of a phenolic aldehyde epoxy acrylate resin, 2-6 parts of a difunctional polycarbonate polyurethane acrylate resin, 3-6 parts of pentaerythritol triacrylate, 5-10 parts of trimethylolpropane triacrylate, 2-3 parts of 184, 0.5-1 part of 819, 0.5-1 part of TPO, 0.1-0.2 part of an organic silicon leveling agent and 23-35 parts of an organic solvent. During preparation, the resin components are first mixed and dispersed at high speed to obtain a mixed resin, then 184, 819 and TPO and the leveling agent are dissolved in part of butyl acetate and stirred, ethyl acetate, ethylene glycol monobutyl ether and the remaining butyl acetate are added, and after dispersion, the primer is filtered to obtain the primer. The primer solves the problems of deep curing, adhesion and leveling of the PBT car lamp primer by accurately matching 184, 819 and TPO, selecting a cyclic structure modified polyurethane acrylate resin and gradient volatile solvents.
