Environment-friendly solvent universal glue and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, and more specifically relates to an environment-friendly solvent-type universal adhesive and a preparation method thereof. Background technique [0002] Universal adhesive is a kind of adhesive with suitable viscosity, which is suitable for scraping construction with toothed squeegee, brush, etc. as construction tools, and closely connects the interfaces of two different substances to play the role of transfer application. Universal glue is widely used in the bonding between aluminum-plastic panels, plywood, density boards, paint-free boards, polymer boards, metal sheets and other materials. All-purpose adhesives include solvent-based all-purpose adhesives (oil-based all-purpose adhesives) and water-based all-purpose adhesives. Although water-based all-purpose adhesives are environmentally friendly, they are strictly limited due to their shortcomings such as slow drying and low init...

Problems solved by technology

[0004] However, due to the use of more toxic organic solvents, the traditional solvent-based universal adhesive can only meet the general standards such as the national standard GB 18583-2001 in terms of environmental protection index, and it is still difficult to Meet high environmental protection standards such as China's environmental labeling certification standard HJ / T 220-2005, IKEA standards, etc., and the application performance such as initial adhesion, holding power, heat resistance and aging resistance, open time, etc. need to be optimized to meet The high-end market needs. In addition, the traditional all-purpose adhesive industry relies too much on oil resources, and the cost of raw materials is deeply affected by the rise in oil
