Abstract

The invention discloses a high-intensity transparent bonding agent and a preparation method thereof. The high-intensity transparent bonding agent is prepared from the following raw materials including silane modified polymers, plasticizers, gas phrase white carbon black, dewatering agents, coupling agents, antioxidants, ultraviolet stabilizers and catalysts, wherein the silane modified polymers are one or several materials in silane modified polyether, silane terminated polyether and silane terminated polyurethane prepolymers. The silane modified polymers are used as substrate resin; the prepared bonding agent has good transparency and high intensity; the bonding sealing requirements in some specific occasions can be completely met; the good bonding performance is realized; the surface bonding and sealing of most substrates can be met; no corrosion is caused on the substrate; the excellent high-low-temperature-resistant performance and weather-resistant performance are realized; the appearance and the performance are kept not to generate obvious change for a long time; an organic tin catalysis scheme can be used; green and environment-friendly effects are achieved; the high-intensity transparent bonding agent can be applicable to some products forbidden to use the organic tin compounds.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and more specifically relates to a high-strength transparent adhesive and a preparation method thereof. Background technique [0002] Adhesives are used in a wide range of industries. In the bonding of some specific parts in the fields of electronic appliances, automobiles and ships, the requirements for adhesives are relatively high. In addition to requiring good bonding performance, there are also high requirements for the transparency, strength, elasticity, high and low temperature resistance, aging resistance, electrical insulation performance, and construction performance of the adhesive. [0003] At present, common transparent adhesives mainly include epoxy resin, acrylic ester, polyurethane, silicone glue and the like. Among them, epoxy resin-based transparent adhesives are brittle after curing, have low elongation, poor impact resistance, and some products have certain toxicity and ir...
