Embodiment 1

[0021] ① Add 10 parts of white naphthenic oil to the reaction boiler that has been preheated to 170-180°C, then increase the temperature of the reaction boiler (ie reaction temperature) to 210°C, and stir for 10 minutes;

[0022] ②Add 25 parts of thermoplastic elastomer and 25 parts of thermoplastic rubber to the reaction boiler described in step ①, and continue stirring at 210°C until the thermoplastic elastomer and thermoplastic rubber melt;

[0023] ③Put 20 parts of terpene resin, 19 parts of rosin glyceride and 1 part of antioxidant into the reaction boiler mentioned in step ②, stir for 90-100 minutes, and then discharge the materials to obtain the non-drying glue glue.

Embodiment 2

[0025] ①Add 13 parts of white naphthenic oil to the reaction boiler that has been preheated to 170-180°C, then raise the temperature of the reaction boiler (ie reaction temperature) to 213°C, and stir for 10 minutes;

[0026] ②Add 23 parts of thermoplastic elastomer and 26 parts of thermoplastic rubber to the reaction boiler described in step ①, and continue stirring at 213°C until the thermoplastic elastomer and thermoplastic rubber melt;

[0027] ③Put 22 parts of terpene resin, 17 parts of rosin glyceride and 1.2 parts of antioxidant into the reaction boiler mentioned in step ②, stir for 90-100 minutes, and then discharge the materials to obtain the non-drying glue glue.

Abstract

The invention relates to hot-melt glue, which comprises the following components in parts by weight: 23-28 parts of thermoplastic elastomer, 22-27 parts of thermoplastic rubber, 16-23 parts of terpene resin, 15-23 parts of rosin glycerol ester, 0.8-1.3 parts of antioxidant, and 8-15 parts of white naphthenic oil. A preparation method for the hot-melt glue comprises the steps: (1) adding the white naphthenic oil into a reaction boiler, and agitating for 10 minutes; (2) adding the thermoplastic elastomer and the thermoplastic rubber, and continuously agitating until the thermoplastic elastomer and the thermoplastic rubber are molten; and (3) then feeding other active ingredients into the reaction boiler, agitating for 90-100 minutes, and discharging, thus obtaining the non-dry adhesive glue. The hot-melt glue is glue with an environment-friendly effect, and the glue prepared by adopting the method has good physical performance, and has the advantages of stable holding power and initial adhesion and the like.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a hot-melt glue and a preparation method thereof. Background technique [0002] In today's society, with the continuous improvement of people's living standards, people pay more and more attention to the environmental protection performance of self-adhesive materials. Demand continues to rise, and environmentally friendly hot-melt self-adhesive materials have become people's first choice, so the preparation of glue for composite materials is particularly important. [0003] At present, most glues used for composite materials have poor stability of stickiness and initial tack, which affects people's usage rate. Contents of the invention [0004] The object of the present invention is to provide a kind of hot-melt glue and preparation method thereof, this hot-melt glue is a kind of glue with environmental protection effect, according to the self-adhesive prepared by this method,...
