Problems solved by technology

[0004] However, after adding inorganic metal hydroxide and organic phosphate particles to the acrylate emulsion, it is easy to cause uneven mixing of the flame retardant in the adhesive, resulting in a large decrease in the bonding performance, and at the same time, the tensile strength is lower than that of the original latex. A certain degree of decline, because the added inorganic particles destroy the original equilibrium system, so that the phase separation of the original rubber is obvious, thereby reducing the tensile strength

Abstract

The invention discloses a flame-retardant polyacrylic ester adhesive and a preparation method thereof. The weight percentages of components are as follows: acrylic ester emulsion: 75%-90%; cross linking agent: 5%-20%; organic phosphorus-nitrogen flame retardant: 1%-5%; and solvent: 1%-10%. The invention aims at providing a flame-retardant polyacrylic ester adhesive with high flame-retardant performance, the flame-retardant degree reaching UL94 HF-2, and improving the adhesion, the heat resistance and the anti-aging performance by adjusting the content of the cross linking agent and adopting special construction technique.

Description

technical field [0001] The invention relates to a polyacrylate adhesive, in particular to a highly cohesive, flame-retardant polyacrylate adhesive and a preparation method thereof. technical background [0002] Pressure-sensitive adhesives are generally coated on various substrates and processed into pressure-sensitive tapes, labels, sheets, etc., and can be firmly bonded to the adherend with only a slight pressure during use. It is easy to use , generally does not affect the surface of the adherend after being lifted, so the application field is very wide, and it has been applied to packaging, automobiles, electronics, construction, aerospace and other departments. According to statistics, the output of China's pressure-sensitive adhesives has jumped to the third place in the world, of which acrylate pressure-sensitive adhesives account for more than 65%. [0003] Halogen-based (such as: chlorine, bromine, etc.) flame retardants can provide high-performance flame-retardant...
