Abstract

The invention discloses an adhesive for tipping paper for cigarettes. The adhesive is prepared from, by weight, 60-70 parts of butyl acrylate, 20-25 parts of vinyl acetate, 12-16 parts of hydroxypropyl acrylate, 6-9 parts of dimethylaminoethyl acrylate, 5-8 parts of 2-acetamidoacrylicacid, 1.7-2.1 parts of azodiisobutyronitrile and 60-80 parts of a mixed solvent. By refining raw material composition and optimizing the content of the raw materials, the butyl acrylate, the vinyl acetate, the hydroxypropyl acrylate, the dimethylaminoethyl acrylate, the 2-acetamidoacrylicacid and the azodiisobutyronitrile in a proper proportion are selected, and respective advantages of the raw materials are given full play to, complement with one another and are mutually promoted, so that the prepared adhesive for the tipping paper for the cigarettes is high in persistent adhesion (holding power), high in 180-degree peeling strength and good in adhesive property. The adhesive for the tipping paper for thecigarettes is good in liquidity and more convenient to use.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive for cigarette tipping paper and a preparation method thereof. Background technique [0002] Acrylic adhesives are a class of adhesives with unique properties and a wide range of applications. According to the form and application characteristics of the adhesive, it can be divided into solvent type, emulsion type, reactive type, pressure sensitive type, instant dry type, anaerobic type, photosensitive type and hot melt type. From this classification, it is not difficult to see that the scope of application of acrylic adhesives is very wide. It can be said that all metal and non-metallic materials can be bonded with acrylic adhesives. Among them, pressure-sensitive adhesives, anaerobic adhesives, photosensitive adhesives, hot-melt adhesives, etc., have basically formed their own systems. The following mainly introduces solvent-based, emulsion-based, reactive acrylic...
