Abstract

The invention discloses an environment-friendly low-whitening instant adhesive. The instant adhesive is composed of the following raw materials: cage-type silsesquioxane / acrylate copolymer modified α-ethyl cyanoacrylate, hydrophilic modified α-n-octyl cyanoacrylate, α-n-butyl cyanoacrylate and additives; described cage silsesquioxane / acrylate copolymer modified α-ethyl cyanoacrylate, hydrophilic modified α- The mass ratio of n-octyl cyanoacrylate, n-butyl α-cyanoacrylate and additives is 1-10:1-10:80-95:0.5-5. The instant adhesive of the invention solves the technical problems of poor heat resistance and aging resistance, strong irritating odor and easy occurrence of whitening phenomenon of traditional instant adhesive. The effect of using instant glue.

Description

technical field [0001] The invention relates to the technical field of instant adhesives, in particular to an environment-friendly low-whitening instant adhesive. Background technique [0002] The main component of instant adhesive is α-cyanoacrylate adhesive, which is a single-component, low-viscosity, transparent, fast-curing adhesive at room temperature. It has a wide bonding surface and has good bonding ability to most materials. It is one of the important room temperature curing adhesives. The glue formed by pure α-cyanoacrylate monomer has too fast reaction speed, high brittleness, poor impact resistance, poor aging resistance and heat resistance, and has a strong pungent smell, which pollutes the environment. [0003] In addition, during the construction of traditional instant adhesives, due to the volatility of α-cyanoacrylate adhesive monomers, it is easy to form a layer of white fog on the rubber surface due to the cross-linking reaction, which seriously affects t...
