Abstract

The invention discloses a preparation method of a high-temperature-resistant high-hardness adhesive. The method includes the following steps of evenly mixing and stirring 188 unsaturated polyester resin, medical stone powder, ground calcium carbonate, argil, mica powder, nano-kaolin, wollastonite powder, epoxidized soybean oil, dispersing agent, modified hyaluronan and water according to weight parts to obtain adhesive mud, evenly mixing and stirring halloysite, sepiolite, glass beads, benzoyl peroxide and water according to weight parts to obtain a curing agent, filling the curing agent and the adhesive mud into a dual-layer thin film bag, and sealing the opening to obtain the high-temperature-resistant high-hardness adhesive. The obtained adhesive is high in polymerization density, hardness, toughness and crack resistant strength and excellent in high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a method for preparing a high-temperature-resistant and high-hardness adhesive. Background technique [0002] Resin adhesives use unsaturated resins as adhesives, limestone powder, etc. as reinforcing materials, and are equipped with a suitable accelerator-initiating system. The produced resin cement can obtain high strength and fast curing effect. Resin adhesives are widely used in the field of electronic packaging technology, but the current performance of resin adhesives in terms of high temperature resistance and hardness cannot meet the needs and needs to be improved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing a high-temperature-resistant high-hardness adhesive. The obtained adhesive has high polymerization density, high hardness, good toughness, ...
