Environment protecting sprayed glue and its preparation and use

Abstract

The invention discloses an environment-friendly spray glue. The optimum weight ratio of the spray glue is: thermoplastic elastomer SBS 8%, rosin 6%, hydrogenated rosin 7%, petroleum resin 4%, tackifying resin 3%, No. 6 Extract solvent oil 49.5%, acetone 5%, cyclohexane 15%, butyl fat 2% and antioxidant 0.5%. The preparation process is as follows: first put quantitative No. 6 extraction solvent oil, acetone, and cyclohexane into the mixer, start the machine to stir evenly to form a mixed solution; then put quantitative thermoplastic elastomer SBS into the mixer and stir; finally Put rosin, hydrogenated rosin, petroleum resin, tackifying resin, butyl fat and anti-aging agent into the mixer and stir at room temperature for about 6 hours to completely dissolve all materials into light yellow glue, then filter through 80 mesh. The environment-friendly spray glue of the invention is non-toxic, low in cost and fast drying, and is especially suitable as an adhesive for making upholstered furniture.

Description

technical field [0001] The invention relates to an adhesive, in particular to an environment-friendly spray adhesive and its production process and application. Background technique [0002] The thermoplastic elastomer SBS solvent-based spray glues that appear on the market currently contain triphenyl (benzene, toluene, xylene) and halogenated hydrogen highly toxic and highly toxic solvents in different proportions. Triphenyl can cause cancer, and halogenated hydrogen It can affect the metabolism of the human body and cause liver poisoning. Whether it is long-term or short-term exposure, it will cause acute and chronic poisoning of the human body to varying degrees, and at the same time cause serious pollution to the surrounding environment. Although the formula of the patent No. 90106727.X solves the problem of toxic pollution, its cost is relatively high, and it is limited to the mounting glue used as a color printing film. In addition, because its formula uses 120# solven...

[0002] The thermoplastic elastomer SBS solvent-based spray glues that appear on the market currently contain triphenyl (benzene, toluene, xylene) and halogenated hydrogen highly toxic and highly toxic solvents in different proportions. Triphenyl can cause cancer, and halogenated hydrogen It can affect human metabolism and cause liver poisoning. Whether it is long-term or short-term contact, it will cause acute and chronic poisoning of the human body to varying degrees, and at the same time cause serious pollution to the surrounding environment.

Although the formula of the patent No. 90106727.X solves the problem of toxic pollution, its cost is relatively high, and it is limited to the mounting glue used as a color printing film. In addition, because its formula uses 120# solvent oil, its drying Long time, thus limiting its application as an adhesive for upholstered furniture
