Problems solved by technology

[0005] At the same time, most of the adhesives prepared for the purpose of environmental protection currently have some deficiencies. Due to the abandonment of low-volatility raw materials, the advantages brought by these raw materials are lost, resulting in insufficient durability and short shelf life of the prepared adhesives. , the performance of the adhesive is unstable, as time goes on, the performance of the adhesive decreases rapidly, and the viscosity of the adhesive is relatively high, and the relative viscosity and adhesion decrease, which increases the difficulty of use

Abstract

The invention relates to the technical field of adhesive, and in particular, relates to an environment-friendly acrylate adhesive and a preparation process thereof. The environment-friendly acrylate adhesive comprises the following raw materials in parts by weight: 600 parts of butyl acrylate, 60 parts of isooctyl acrylate, 55 parts of acrylic acid, 1144 parts of ethyl acetate, 5 parts of 2-hydroxyethyl acrylate, 7 parts of AIBN, and 200 parts of rosin resin. A downstream product of the adhesive has no toluene volatilization, and has friendly environmental performance; at the same time, due to the preparation process of the product, a split charging method is adopted, the occurrence of explosive polymerization is effectively prevented, and the dispersion degree of the product is high; and through the split charging process, the performance of the product is controlled and improved, so that the product has a predetermined viscosity, and the amount of VOC of the downstream product is decreased significantly.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly acrylate adhesive and a preparation process thereof. Background technique [0002] Adhesive, also known as adhesive, referred to as glue (bonding agent, adhesive), is a non-metallic medium material that makes an object closely connected with another object. The adhesive only occupies a very thin layer of volume between the two adherend surfaces, but after the adhesive is used to complete the bonding construction, the obtained adhesive joints can meet various requirements of actual needs in terms of mechanical properties and physical and chemical properties. It can effectively bond materials together. [0003] Acrylic adhesives have a wide range of raw materials, simple preparation process, rapid drying and molding, good transparency, good bonding performance to various materials, and good weather resistance, water resistance, and chemical resistance. I...
