Embodiment 1

[0011] Stir and mix 4 parts of isopropanol, 20 parts of methyl ethyl ketone, and 12 parts of vinyl acetate. After heating up, add 14 parts of trimethoxysilane, 10 parts of carbon tetrachloride, 12 parts of styrene, and benzene peroxide 7 parts of formyl, 16 parts of difluorotetrachloroethane, after reacting for 2 hours, add 6 parts of butyl acetate, 14 parts of sodium benzoate, 8 parts of methyl cellulose, 10 parts of stearic acid, 6 parts of perchloroethylene resin 4 parts of trimethoxysilane were placed in a thermostatically controlled water bath at 38°C, and the pH value was adjusted to 7.8 by a pH meter. After the reaction, sample 1 was obtained.

Embodiment 2

[0013] Stir and mix 4 parts of isopropanol, 22 parts of methyl ethyl ketone, and 14 parts of vinyl acetate. After heating up, add 16 parts of trimethoxysilane, 10 parts of carbon tetrachloride, 14 parts of styrene, and benzene peroxide 6 parts of formyl, 14 parts of difluorotetrachloroethane, after reacting for 2 hours, add 6 parts of butyl acetate, 16 parts of sodium benzoate, 10 parts of methyl cellulose, 10 parts of stearic acid, and 8 parts of perchloroethylene resin 5 parts, 5 parts of trimethoxysilane were placed in a thermostatically controlled water bath at 42°C, and the pH value was adjusted to 8.0 by a pH meter. After the reaction, sample 2 was obtained.

Embodiment 3

[0015] Stir and mix 6 parts of isopropanol, 25 parts of methyl ethyl ketone, and 16 parts of vinyl acetate. After heating up, add 18 parts of trimethoxysilane, 14 parts of carbon tetrachloride, 16 parts of styrene, and benzene peroxide 8 parts of formyl, 12 parts of difluorotetrachloroethane, after reacting for 2 hours, add 8 parts of butyl acetate, 18 parts of sodium benzoate, 12 parts of methyl cellulose, 14 parts of stearic acid, and 12 parts of perchloroethylene resin 6 parts, 6 parts of trimethoxysilane were placed in a thermostatically controlled water bath at 45°C, and the pH value was adjusted to 8.5 by a pH meter. After the reaction, sample 3 was obtained.

[0016]

[0017] After checking the usability of the glue of the three samples, it can be obtained that the viscosity of the sample 2 is the largest, and it is not easy to open the glue after use, and has good heat resistance, so Example 2 is the optimal synthesis method.

Abstract

The invention provides a synthesis method of glue. Raw materials of the glue comprise 4-6 parts of isopropanol, 20-25 parts of methyl ethyl ketone, 12-16 parts of vinyl acetate, 12-18 parts of trimethoxysilane, 10-14 parts of carbon tetrachloride, 10-16 parts of styrene, 6-8 parts of benzoyl peroxide, 14-20 parts of difluorotetrachloroethane, 6-10 parts of butyl acetate, 14-18 parts of sodium benzoate, 8-12 parts of methyl cellulose, 8-14 parts of stearic acid, 6-12 parts of vinylidene chloride resin and 4-6 parts of trimethoxysilane. The synthesis method has the advantages of low cost of theraw materials needed by the synthesis, high viscosity, and no overflowing of toxic and harmful gases.

Description

technical field [0001] The invention relates to the field of chemical synthesis, in particular to a method for synthesizing glue. Background technique [0002] Glue is an intermediate that connects two materials, and it mostly appears as a water agent. It belongs to the fine chemical industry and has a wide variety. The common ones are instant glue, epoxy resin bonding, anaerobic glue, hot melt adhesive, etc. The application range of glue is getting wider and wider. However, harmful chemicals such as toluene and methanol are often added in the existing glue synthesis process, resulting in relatively large pollution in the production process, which does not meet today's environmental protection requirements, and has an impact on user use. At the same time, the existing glue synthesis method has irrational feeding ratio, resulting in low glue yield, low glue viscosity, increased production cost, and poor glue performance. In the glue synthesis method of the present invention...
