Embodiment Construction

[0010] A high-temperature resistant heat-sealing adhesive used in pharmaceutical aluminum foil packaging, made of the following raw materials in parts by weight (kg): dimethyldichlorosilane 14, ethyl acetate 26, methyl ethyl ketone 14, EVA emulsion 20, isomerized ten Triol polyoxyethylene ether 1, anilinomethyltriethoxysilane 3, tert-butyl hydroperoxide 2, acrylonitrile 5, isoprene 6, abietic acid polyoxyethylene ester 2, tackifier 5.

[0011] The tackifier is prepared from the following raw materials in parts by weight (kg): thermoplastic acrylic resin 3, silane coupling agent KH5702, 582-2 amino resin 4, 2-hydroxypropyl acrylate 3, butyl acetate 6 , alum powder 0.4, styrene 6;

[0012] The preparation method is: add thermoplastic acrylic resin and 582-2 amino resin to butyl acetate, heat to 110-120°C, then add styrene, stir for 40-60 minutes, then add alum powder, acrylic acid-2-hydroxy Propyl ester, silane coupling agent KH570, stirring reaction for 2-3 hours, that is.

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. During packaging, paper-plastic bonding, paper-paper bonding, and plastic-iron bonding all need to be used for packaging adhesives. Most of the existing packaging heat-sealing adhesives have toxic solvent residues, and the bonding strength is not high. question. It cannot meet the current packaging harmless bonding needs. Contents of the invention [0003] The object of the present invention is to provide a high-temperature-resistant heat-sealing adhesive applied to pharmaceutical aluminum foil packaging and a preparation method thereof. [0004] The technical scheme adopted in the present invention is: [0005] A high-temperature-resistant heat-sealing adhesive a...
