The invention discloses an environment-friendly
solvent universal glue and a preparation method thereof. The best weight ratio of the universal glue is 9% of starburst SBS
thermoplastic styrene-butadiene rubber, 2% of linear SBS
thermoplastic styrene-butadiene rubber, 7% of
rosin, 9.5% of hydrogenated
rosin, 4% of C9
petroleum resin, 6% of a tackifying resin, 15% of No. 6 extraction
solvent oil, 30% of methylal, 15% of
methyl acetate, 0.2% of a
wetting agent, 0.8% of an anti-aging agent, 0.5% of an
antioxidant and 1.0% of a
softening agent. The environment-friendly
solvent universal glue has the comprehensive superiorities of low VOC, high
solid content, no
heavy metals, low smell, excellent initial adhesion, excellent
cohesive strength, excellent permanent adhesion, excellent heat-resistant and
ageing-resistant performance, short
drying time, long opening time, large spraying area per weight (glue economization), and the like, has the advantages of reducing environment
pollution, improving operation and construction environment, being low cost and low smell, and the like, is widely used in plate decoration industries of aluminum-plastic plates, clamping plates, density plates, paint-free plates,
polymer plates,
metal sheets, and the like, and is particularly suitable for applications in green high-grade decoration industries.
