Problems solved by technology

[0003] Neoprene was mainly effective in the early super glue, which has good bonding performance to soft and hard materials such as wood, aluminum-plastic panels, leather, artificial leather, plastics, rubber, and metal, but its production process is more complicated and costly. Higher, and need to use some specific solvents to dissolve, which is harmful to the environment and the health of operators. In order to replace the previous all-purpose adhesive, there are more SBS thermoplastic elastomers on the market to replace the previous neoprene rubber. The existing SBS adhesive has the advantages of simple and convenient use and low toxicity, but it has the disadvantage of poor adhesion to polar substrates such as high-hardness aluminum alloys and PVC.

Embodiment 1

[0048] First take a reactor and control the temperature in the reactor to be 35-40°C, add 10 parts by weight of PVC paste resin and 60 parts by weight of mixed solvent (the mixed solvent is petroleum ether, 120# solvent naphtha, acetic acid butyl ester, tetrahydrofuran and cyclohexane in a weight ratio of 30:7:8:5:10), fully stirred, and dissolved the PVC paste resin in the mixed solvent, and then slowly added 10 Parts by weight of thermoplastic styrene-butadiene rubber (the thermoplastic styrene-butadiene rubber is a mixture of YH-792SBS rubber and YH-802SBS rubber in a weight ratio of 2:1), and then the reaction kettle is sealed and the temperature in the kettle is 25-30℃ Stir continuously under the conditions, and after the above-mentioned thermoplastic styrene-butadiene rubber is dissolved, add 15 parts by weight of tackifying resin (the tackifying resin is a mixture of C9 petroleum resin and rosin in a weight ratio of 6:4), and then Reduce the temperature in the kettle to...

Embodiment 2

[0051] The preparation method of embodiment 2 is exactly the same as that of embodiment 1. For the sake of simplicity, the same content will not be repeated here. The ratio of each component of the SBS adhesive used for bonding polar substrates in embodiment 2 is as follows: Mixed solvent: 70 parts by weight (the mixed solvent is a mixture of petroleum ether, 120# solvent oil, butyl acetate, tetrahydrofuran, and cyclohexane in a weight ratio of 30:7:8:5:10), thermoplastic styrene-butadiene rubber : 20 parts by weight (the thermoplastic styrene-butadiene rubber is a mixture of YH-792SBS rubber and YH-802SBS rubber in a weight ratio of 2:1), PVC paste resin: 5 parts by weight, tackifying resin: 8 parts by weight (the increaser The adhesive resin is a mixture of C9 petroleum resin and rosin in a weight ratio of 6:4), anti-aging agent: 2 parts by weight (the anti-aging agent is a mixture of one or more of amine and phenolic anti-aging agents).

[0052] Thereafter, the SBS adhesive...

Embodiment 3

[0054] The preparation method of embodiment 3 is exactly the same as that of embodiment 1 and 2. For the sake of simplicity, the same content will not be repeated here. The ratio of each component of the SBS adhesive used for bonding polar substrates in embodiment 3 is Bottom: Mixed solvent: 65 parts by weight (the mixed solvent is a mixture of petroleum ether, 120# solvent naphtha, butyl acetate, tetrahydrofuran, and cyclohexane in a weight ratio of 30:7:8:5:10), thermoplastic butyl Styrene rubber: 15 parts by weight (the thermoplastic styrene-butadiene rubber is a mixture of YH-792SBS rubber and YH-802SBS rubber in a weight ratio of 2:1), PVC paste resin: 7 parts by weight, tackifying resin: 10 parts by weight ( The tackifying resin is a mixture of C9 petroleum resin and rosin in a weight ratio of 6:4), anti-aging agent: 3 parts by weight (the anti-aging agent is a mixture of one or more of amine and phenolic anti-aging agents).

[0055] Thereafter, the SBS adhesive obtained...

Abstract

The invention provides an SBS (styrene-butadiene-styrene) adhesive for bonding polar substrates and a preparation method of the adhesive and relates to the technical field of adhesives. The adhesive comprises components in parts by weight as follows: 60-70 parts of a mixed solvent, 10-20 parts of SBS rubber, 5-10 parts of PVC (polyvinyl chloride) paste resin, 8-15 parts of tackifying resin and 2-4 parts of an anti-aging agent, wherein the SBS rubber is one of thermoplastic styrene-butadiene rubber adopting linear and star structures or a mixture formed by the thermoplastic styrene-butadiene rubber adopting the linear and star structures, the mixed solvent is a mixture of two or more of petroleum ether, No.120 solvent oil, ethyl acetate, tetrahydrofuran and cyclohexane, the tackifying resin is a mixture of one or more of rosin, petroleum resin and terpene resin, and the anti-aging agent is a mixture of one or more of amine and phenol anti-aging agents. The SBS adhesive for bonding the polar substrates has better bonding performance for the polar substrates, the usage performance of existing SBS adhesives is improved, and the usage range of the SBS adhesive is enlarged.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an SBS adhesive used for bonding polar substrates and a preparation method thereof. Background technique [0002] SBS thermoplastic elastomer is a block copolymer of styrene and butadiene. It has both the solubility and thermoplasticity of styrene, and the flexibility and resilience of butadiene rubber. It is a material with dual characteristics of thermoplastics and vulcanized rubber. . SBS has good solubility, is compatible with many polymers, does not need mixing and plasticizing, does not need high temperature and high pressure vulcanization, is very suitable for the preparation of adhesives, and has the advantages of high strength, good toughness, fast curing and simple construction. [0003] Neoprene was mainly effective in the early super glue, which has good bonding performance to soft and hard materials such as wood, aluminum-plastic panels, leather, artificial leathe...
