Abstract

The invention discloses a high-temperature-resistant solvent-type acrylate pressure-sensitive adhesive which is characterized by being synthesized from, by weight, 7-13% of hard monomer, 23-37% of soft monomer, 2-5% of functional monomer, 0.5-0.9% of heat-resistant monomer and 50% of solvent. The pressure-sensitive adhesive is high in resistance to high temperature, high in adhesiveness and high in adhesive force; when in use, there is no adhesive residue, and higher requirements of the present adhesive market on the pressure-sensitive adhesive are met with excellent performance; lignin which serves as the heat-resistant monomer is from an organism and belongs to renewable resources, so that the environment problem caused by utilizing petroleum resources is solved effectively.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-temperature-resistant solvent-type acrylate pressure-sensitive adhesive and a manufacturing method thereof. Background technique [0002] Adhesive refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesive, which has the characteristics of continuous stress distribution, high viscosity, no residual glue, light weight and convenient use. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components, such as steel, wood, plastic and objects used in special environments. Nowadays, adhesives are developing rapidly and have a wide range of applications. [0003] Adhesives can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type and so on according to the application method. [0004] Pressure-sens...
