Abstract
The invention discloses high temperature-resistant heat-sealing glue for medicinal aluminum foil package and a preparation method thereof. The high temperature-resistant heat-sealing glue is prepared from 12-14 parts by weight of dimethyl dichlorosilane, 24-26 parts by weight of ethyl acetate, 12-14 parts by weight of ethyl methyl ketone, 20-24 parts by weight of EVA emulsion, 1-2 parts by weight of iso-tridecanol polyoxyethylene ether, 2-3 parts by weight of anilino-methyl-triethoxysilane, 1-2 parts by weight of tert-butyl hydroperoxide, 4-5 parts by weight of acrylonitrile, 6-7 parts by weight of isoprene, 1-2 parts by weight of rosin-polythylene oxide ester and 4-5 parts by weight of a tackifying promoter. The high temperature-resistant heat-sealing glue is soft, has light weight, high heat-sealing strength, good oil resistance and solvent resistance, good high-temperature stewing resistance, excellent heat insulation and barrier properties, good wetability to pigment, good transparency, high glossiness and no influence on a substrate color, does not contain a benzene-like solvent and has good safety.
Description
technical field [0001] The invention relates to a heat-sealing adhesive, more specifically, a high-temperature-resistant heat-sealing adhesive applied to pharmaceutical aluminum foil packaging and a preparation method thereof. Background technique [0002] The packaging industry has a large scale in my country.
