Problems solved by technology

The disadvantages are that the reaction speed is too fast, the water resistance is poor, the brittleness is large, the temperature resistance is low, the storage period is short, and the durability is not good, so the corresponding additives should be added when compounding the glue, and it is mostly used for temporary bonding.

Abstract

The invention discloses a heat resistance instant dry adhesive and a preparation method thereof. The heat resistance instant dry adhesive comprises the following components in parts by weight: 80 to 90 parts of ethyl cyanoacrylate, 2 to 8 parts of ethyl cyanoacrylate, 2 to 6 parts of silica, 0.3 to 1 part of nitrobenzene, 0.5 to 2 parts of polyethylene glycol, 0.5 to 1 part of hydroquinone, 5 to 10 parts of polyvinyl acetate, 0.1 to 0.5 part of methanesulfonic acid and 0.05 to 0.1 part of sulfur dioxide. The preparation method comprises the following steps: adding the ethyl cyanoacrylate, the ethyl cyanoacrylate, the nitrobenzene, the hydroquinone, the polyvinyl acetate, the silica, the polyethylene glycol, the methanesulfonic acid and the sulfur dioxide into a reaction kettle; sufficiently stirring and uniformly mixing; heating to a temperature of 70 to 80 DEG C and performing the reaction for 50 to 80 minutes to be a paste state. The heat resistance instant dry adhesive provided by the invention can be rapidly gelled and meanwhile, also can achieve a good binding effect under high temperature conditions of 80 DEG C and 120 DEG C.

Description

technical field [0001] The invention belongs to the field of chemical adhesives, in particular to a heat-resistant instant-drying adhesive and a preparation method thereof. Background technique [0002] As the name implies, instant adhesive is glue that can be used immediately and quickly. It is mainly based on α-ethyl cyanoacrylate, adding tackifiers, thickeners, stabilizers, tougheners, inhibitors, etc., through advanced production A one-component fast-curing adhesive synthesized by technology; it is a high-strength, fast adhesive that can be used for high-speed bonding of various types of materials, especially suitable for use in the wood industry; for tight fit, porous materials, such as rubber , metal, plastic, wood, etc. can achieve the strongest bonding effect; this glue is a single component, no solvent, no need to add catalyst, heat or pressure adhesive, only need a thin layer of glue, it can be used Atmospheric humidity in the air produces a high degree of polyme...
