preparation example Construction

[0035] The raw materials for the preparation of the instant adhesive include: 55-80 parts of ethyl α-cyanoacrylate, 10-40 parts of thickener, 0.05-0.3 parts of plasticizer, 1-3 parts of organic solvent, 0.5 parts of graphene ~5 parts, and 0.5~5 parts of carbon nanotubes.

[0036] In at least one embodiment, the thickener is methyl methacrylate-ethyl acrylate copolymer, polymethacrylate, polyvinyl acetate, polyacrylate, polyvinyl acetal, and polyvinyl acetate at least one of esters. The thickener can undergo radical polymerization reaction with ethyl α-cyanoacrylate to increase the viscosity of the instant adhesive.

[0037] In at least one embodiment, the plasticizer is dioctyl phthalate, dimethyl phthalate, diethyl phthalate, dibutyl phthalate, and dioctyl phthalate at least one of . The plasticizer can weaken the physical effect of polymer intermolecular force, so that the instant adhesive has better toughness and mechanical strength.

Abstract

The invention provides an instant-dry adhesive and a preparation method thereof. The instant-dry adhesive is prepared from the following raw materials in parts by weight: 55 to 80 parts of alpha-ethyl cyanoacrylate, 10 to 40 parts of thickening agent, 1 to 3 parts of organic solvent, 0.5 to 5 parts of graphene and 0.5 to 5 parts of carbon nano tube. The invention also provides a preparation method of the instant-dry adhesive. The instant-dry adhesive has the advantages of being high in water resistance, impact resistance, high temperature resistance and corrosion resistance, and also has good binding power during construction in a water medium.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an instant adhesive and a preparation method of the instant adhesive. Background technique [0002] The existing instant-drying adhesive has the advantages of wide bonding surface and strong bonding ability, and is considered to be one of the most important room temperature curing adhesives. However, the existing instant-drying adhesive not only has the disadvantages of poor water resistance, impact resistance, high temperature resistance, and corrosion resistance, but also has the disadvantage of poor cohesive force when applied in an aqueous medium. Contents of the invention [0003] The main purpose of the present invention is to provide an instant-drying adhesive, which aims to provide strong water resistance, impact resistance, high temperature resistance, and corrosion resistance, and also has better adhesion when applied in water medium. Strong instant drying...
