Abstract

The invention discloses a waterproof UV glue which mainly comprises the following components in percentage by weight: 20%-40% of bifunctional modified polyurethane resin, 15%-35% of acrylic acid-grafted epoxy resin, 10%-25% of hydroxypropyl methacrylate, 10%-25% of isobornyl acrylate, 1%-5% of 1-hydroxy-cyclohexyl phenyl ketone, 0.1%-5% of 2,4,6-trimethybenzoyl- diphenylphosphine oxide and 0.05%-2% of a fluorescent agent. Meanwhile, in order to further improve the application performance of the waterproof UV glue, the waterproof UV glue also comprises 0.05%-5% of microcrystalline cellulose.

Description

technical field [0001] The invention relates to a glue, in particular to a waterproof UV glue. Background technique [0002] In the fields of computers, mobile phones, TVs, air conditioners, refrigerators, medical equipment, aerospace and other fields, when bonding glass, metal, plastic and other materials, due to the poor adaptability of the materials after bonding, there are UV intolerance to water boiling and slow light curing speed. , Long curing heating time, high curing temperature, low strength after curing, poor temperature resistance, poor acid and alkali resistance, poor sag resistance, easy delamination of glue and other problems. In order to solve the above problems, the above problems are improved by adjusting the glue components and their proportions, and at the same time increasing the components that the existing glue does not have. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof UV glue, which can meet th...
