AI Technical Summary

Benefits of technology

This patented technology provides an improved type of glue that overcomes issues with existing types such as clearness or lacking clarity when used alone due to air pockets during curing. Additionally it does this without causing damage from acidic chemicals commonly found inside cathode ray tubes (CRT).

Problems solved by technology

The technical problem addressed in this patented text relates how current acrylate sheets have low clarity when they stick onto screens due to their own properties that can cause them to lose its effectiveness overtime or become damaged during storage. This results in poor quality pictures being produced with these types of materials.

Abstract

The invention provides an acrylic bonding agent and a preparation method thereof. The bonding agent is prepared from the following materials in parts by weight: 10 to 60 parts of phenol, 5 to 20 partsof glacial acetic acid and 1 to 30 parts of dichloromethane. After the acrylic bonding agent is used for bonding acrylic and images, the transparency is good; no bubble exists; image corrosion cannotoccur, so that the acrylic and the images can be perfectly bonded; the color change can be avoided for a long time; bubbles can not be generated; the problems of easy color change, poor transparency,bubble generation on the surface of the existing bonding agents in the market can be well solved.
