Abstract

The invention discloses glue based on graphene modification. The glue is prepared from polyurethane, chloroprene rubber, polyacrylate, graphene, triallylisocyanurate, ethidene diamine, n-butyl alcohol, methylbenzene, potassium stearate, polyethylene imidacloprid network flavanone and N-phenyl-beta-naphthylamine. A preparation method comprises the following steps of (1) adding the graphene into the n-butyl alcohol and the methylbenzene, and ultrasonically dispersing uniformly to obtain a mixed solution A; (2) adding the polyurethane, the chloroprene rubber and the polyacrylate into a reactor for reaction, and sequentially adding the mixed solution A obtained in the step (1), the triallylisocyanurate, the potassium stearate, the polyethylene imidacloprid network flavanone and the N-phenyl-beta-naphthylamine into the reactor for reaction to obtain a mixture B; (3) stopping the reaction, when the temperature cools to 80 DEG C, adding the ethidene diamine into the reactor, stirring uniformly, and preparing the glue based on the graphene modification. The glue prepared by the invention can maintain higher cohesiveness under a high temperature condition, has better high temperature resistance, and is very suitable to be used as high-temperature glue.

Description

technical field [0001] The invention relates to a glue, in particular to a graphene-based modified glue. Background technique [0002] Glue is an intermediate that connects two materials, mostly in the form of water, belonging to the category of fine chemicals, with a wide variety, mainly classified by adhesive, physical form, hardening method and adherend material. Common instant glues such as 502α-ethyl cyanoacrylate, epoxy resin adhesives, anaerobic glues, UV glues, hot melt adhesives, pressure sensitive adhesives, latex, etc. Although the role of glue is great, there are also many shortcomings. The cured epoxy resin glue is generally brittle, with poor peeling resistance, crack resistance, and impact resistance. The raw materials contain varying degrees of toxicity and irritation; silicone glue is suitable for large Cure time for area bond is too long. [0003] Graphene has become one of the research hotspots in the field of materials science. Graphene is actually a s...
