Embodiment 1

[0025] Control the temperature in the reactor at 10-25°C, add 45 parts of solvent (including 15 parts of 120# solvent oil, 10 parts of dimethyl carbonate and 20 parts of petroleum ether) into the reactor, and then slowly add 15 parts of thermoplastic Styrene-butadiene rubber (including 10 parts of YH-792 and 5 parts of YH-802SBS rubber); control the temperature in the reactor to 10-25°C, keep the reactor closed and continue to stir, and then add the thermoplastic styrene-butadiene rubber after it dissolves 25 parts of tackifying resin (including 8 parts of C9 petroleum resin, 10 parts of hydrogenated rosin glyceride and 7 parts of terpene resin); keep the same temperature as before and stir in airtight, after the tackifying resin is completely dissolved, add 5 parts of anti-salt Fog aid, 5 parts of silane coupling agent, 5 parts of anti-aging agent, stir evenly, pour the adhesive out of the reaction kettle, and filter to obtain the salt spray-resistant SBS adhesive of this embo...

Embodiment 2

[0028] Compared with Example 1, Example 2 only has a change in the weight ratio of each component, and the other contents are exactly the same. For the sake of simplicity, the same contents will not be repeated here. The weight ratio of each component is as follows:

[0029] 25 parts of thermoplastic styrene-butadiene rubber (including 15 parts of YH-792SBS rubber and 10 parts of YH-802SBS rubber), 10 parts of tackifying resin (including 6 parts of C9 petroleum resin and 4 parts of hydrogenated rosin glyceride), salt spray resistance additive 0.1 part, 0.1 part of silane coupling agent, 0.1 part of anti-aging agent, 60 parts of solvent (including 15 parts of ethyl acetate, 10 parts of dimethyl carbonate, 8 parts of kg butyl acetate, 7 parts of petroleum ether, 20 parts of 120# solvent Oil).

[0030] Thereafter, the salt spray-resistant SBS adhesive obtained in Example 2 was also made into a shear sample (adhesive material is 1060 aluminum sheet and PVC floor leather) and cure...

Embodiment 3

[0032] Embodiment 3 compares with embodiment 1 and 2, only the weight proportion of each component changes, and other contents are identical, and the weight proportion of each component of embodiment 3 is as follows:

[0033]17 parts of thermoplastic styrene-butadiene rubber (including 10 parts of YH-792SBS rubber and 7 parts of YH-802SBS rubber), 25 parts of tackifying resin (including 8 parts of C9 petroleum resin, 10 parts of hydrogenated rosin glyceride, 7 parts of terpene resin) , 4 parts of salt spray resistance additive, 3 parts of silane coupling agent, 2.5 parts of anti-aging agent, 48.5 parts of solvent (including 15 parts of ethyl acetate, 10 parts of dimethyl carbonate, 4 parts of butyl acetate, 7 parts of petroleum ether, 12.5 parts of 120# solvent oil).

[0034] Thereafter, the same salt spray-resistant SBS adhesive obtained in Example 3 was also made into a shear sample (adhesive material is 1060 aluminum sheet and PVC floor leather) and cured into an adhesive f...

Abstract

The invention provides a salt spray resistant SBS adhesive and a preparation method thereof, relating to the technical field of adhesives. The adhesive comprises the following components in parts by weight: 15-25 parts of thermoplastic butadiene styrene rubber, 10-25 parts of tackifying resin, 0.1-5 parts of salt spray resistant additives, 0.1-5 parts of silane coupling agent, 0.1-5 parts of anti-aging agent and 45-60 parts of solvent. The salt spray resistant SBS adhesive sends out small amount of pungent smell in actual use, has better environment friendliness, also has very excellent salt spray resistance and can well meet the operating requirements of coastal or high salt spray environments.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a salt spray-resistant SBS adhesive 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. However, most of the SBS adhesives currently on the market have the disadvantages of volatile organic solvents, poor environmental protection, and resistance to aging and salt spray, which greatly limits t...
