Problems solved by technology

[0008] At present, adhesives are widely used and can meet the basic needs of use. However, for the glass glue used to bond glass, especially the glass glue used in the furniture decoration industry, the bonding time is generally longer, and the glass glue will occur during long-term use. The discoloration effect is mainly due to the oxidation and discoloration of the surface of the glass glue due to light, which affects the aesthetics

Abstract

The invention discloses glass cement and a preparation method thereof. The glass cement is prepared from the following components: 2-ethyl cyanoacrylate, polyvinyl butyral, soft butadiene styrene rubber, diethylamino ethyl methylacrylate, carnauba wax, an anti-oxidant, stearic acid, sodium silicate, silicon dioxide, polyethylene glycol and aluminum oxide. A preparation process comprises the following steps: uniformly mixing the 2-ethyl cyanoacrylate, the soft butadiene styrene rubber, the polyvinyl butyral and the carnauba wax, thus obtaining a mixture I; then transferring the mixture I into a reaction kettle, adding the diethylamino ethyl methylacrylate, the sodium silicate, the silicon dioxide and the aluminum oxide, and heating and reacting under a vacuum condition, thus obtaining a mixture II; finally, adding the anti-oxidant, the stearic acid and the polyethylene glycol into the mixture II, and uniformly stirring and mixing, thus obtaining the glass cement. The glass cement provided by the invention has good adhesion performance and good light aging resistance, and can be well applied to glass adhesion.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a glass glue and a preparation method thereof. Background technique [0002] Adhesive refers to a class of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through interface adhesion and cohesion. , collectively referred to as adhesives, also known as adhesives, customarily referred to as glue. Adhesives are generally mainly composed of the following components: [0003] (1) Adhesive substance: Adhesive substance is also called sticky material, which is the basic component in adhesive and acts as a bond. Its properties determine the performance, use and conditions of use of the adhesive. Generally, various resins, rubbers and natural polymer compounds are used as bonding substances. [0004] (2) Curing agent: The curing agent is a component that promotes the curing of the bonding substance through a chemical re...
