Abstract

The invention provides high-elasticity and high-stretchability shadowless glue and a preparation method thereof. The high-elasticity and high-stretchability shadowless glue is prepared from the following raw materials in percentage by weight: 30-50% of polyurethane acrylate, 1-5% of 2,4,6-trimethylbenzoyl-diphenyl phosphine oxide, 1-5% of 1-hydroxycyclohexyl phenyl ketone, 20-35% of hydroxyethyl methacrylate, 20-35% of isobornyl acrylate, 1-5% of methyl acrylate and 1-5% of 3-(2,3-epoxypropoxy)propyltrimethoxysilane. Compared with the prior art, the product provided by the invention has the characteristics of high stretchability, favorable weather resistance and high bonding strength, is long in service life, and can absorb the stress of a bonded product so as to solve the problem on shock absorption in the bonding position. Besides, the UV (ultraviolet) glue provided by the invention is soft in texture but not the existing hard lump.

Description

technical field [0001] The invention relates to a shadowless glue with high elasticity and high stretchability and a preparation method thereof. Background technique [0002] Shadowless glue is also called UV glue, photosensitive glue, and ultraviolet light curing glue. Shadowless glue refers to a type of adhesive that must be cured by ultraviolet light. It can be used as an adhesive or as a paint, coating, ink, etc. glue used. It has a wide range of applications, and the bonding between plastics and various materials has excellent bonding effects; the bonding strength is high, and the destructive test can achieve the effect of breaking the plastic body in a few seconds, and reach the highest strength in one minute, which greatly improves Work efficiency; completely transparent after curing, the product will not yellow or whiten for a long time; [0003] Compared with traditional instant adhesive bonding, it has the advantages of ring test resistance, no whitening, and goo...
