Embodiment 1

[0011] A method for preparing a diamond-sticking adhesive. Add 10 g of acrylic acid, 40 g of methyl acrylate, 50 g of dimethyl succinate, and 1 g of azobisisobutyronitrile (AIBN) into a three-necked flask, start stirring, and pass nitrogen gas for 15 minutes, then heat up to 75°C, react for 3 hours, and continue to blow nitrogen. Add 5g of nano-scale carbon black after the reaction is over, increase the stirring speed, and form a black non-drawing sticky diamond glue.

Embodiment 2

[0013] A method for preparing diamond-sticking adhesive, add 5g of acrylic acid, 5g of ethyl acrylate, 40g of methyl acrylate, 50g of dimethyl succinate, and 2g of azobisisobutyronitrile (AIBN) into a three-necked flask, start stirring, and blow nitrogen After 15 minutes, the temperature was raised to 80° C., and the reaction was carried out for 3.5 hours, and the nitrogen gas flow was continued. Add 5g of nano-scale carbon black after the reaction is over, increase the stirring speed, and form a black non-drawing sticky diamond glue.

Embodiment 3

[0015] A method for preparing a diamond-sticking adhesive, adding 5g of acrylic acid, 3g of vinyl acetate, 40g of methyl acrylate, 5g of isooctyl acrylate, 50g of dimethyl succinate, and 2.5g of azobisisobutyronitrile (AIBN) into a three-necked flask In the middle, start stirring, blow nitrogen for 12 minutes, raise the temperature to 70° C., react for 4 hours, and continue blowing nitrogen. Add 5g of nano-scale carbon black after the reaction is finished to form a black non-drawing sticky diamond glue.

Abstract

The invention relates to a chemical adhesive, and specifically relates to a diamond adhesive and a preparation method thereof. The diamond adhesive is a dimethyl succinate solution of polyacrylic acid. A nano-grade inorganic powder with an amount of (1-10)% by weight of the polyacrylic acid dimethyl succinate solution is added into the solution. The polyacrylic acid is formed by a polymerization reaction of an acrylic acid monomer and azobisisobutyronitrile (AIBN). The azobisisobutyronitrile (AIBN) accounts for (1-5)% by weight of the acrylic acid monomer. In the preparation method, the polyacrylic acid is dissolved in dimethyl succinate; azobisisobutyronitrile (AIBN) accounting for (1-5)% by weight of the polyacrylic acid is added; the material is heated to 65-90 DEG C, and a reaction is carried out for 3-4h, such that the dimethyl succinate solution of polyacrylic acid is formed. The adhesive provided by the invention has the characteristics of good environment friendliness, high adhesive strength, and no drawing.

Description

technical field [0001] The invention relates to a chemical adhesive, in particular to a drill adhesive and a preparation method thereof. Background technique [0002] At present, E6000 is commonly used in the DIY market for artificial drill placement. E6000 is a neoprene rubber soluble in tetrachloroethane. When the glue is applied, tetrachloroethane volatilizes into the air to dry to form a cohesive force. Tetrachloroethane is not very irritating but has anesthetic and inhibitory effects on the central nervous system and can cause liver, kidney and myocardial damage. Tetrachloroethane is very volatile, so after the glue is placed on the position to be bonded, the glue will dry quickly, and if the operation is not done in time, the bond will not be achieved. Another defect of E6000 is that chloroprene rubber contains chlorine, which will form highly toxic chlorine-containing compounds when it catches fire, which will cause people to suffocate and die; another defect that is...
