Embodiment 1
[0067] This embodiment provides a kind of high-adhesive emulsion used for cigarette pack film, which consists of the following raw materials in parts by weight:
[0068] Phase A: 320 parts of acrylic resin, 285 parts of deionized water, 30 parts of cationic emulsifier, and 20 parts of anionic emulsifier; among them, the cationic emulsifier is made of dodecyl chloride with a weight ratio of 1:1:1 A mixture of ammonium chloride, cetyltrimethylammonium bromide and cetylpyridinium bromide; the anionic emulsifier is a mixture of oleic acid soap and stearic acid in a weight ratio of 1:1:1:1 A mixture of sodium, fatty acid polyether sulfate and sodium alkylsulfonate.
[0069] Phase B: 3 parts of 1,6-hexanediol diacrylate, 10 parts of the first monomer composed of hydroxyethyl acrylate, 150 parts of the second monomer composed of butyl acrylate, composed of hydroxyethyl methacrylate 3 parts of the third monomer, 38 parts of the fourth monomer composed of butyl methacrylate, 144 parts...
Embodiment 2
[0088] In this example, on the basis of Example 1, the first monomer in Phase B is changed to be composed of propyl acrylate, and the rest is the same as Example 1.
Embodiment 3
[0090] In this example, on the basis of Example 1, the second monomer in phase B is changed to be composed of isooctyl acrylate, and the rest is the same as that of Example 1.

Abstract
The invention discloses a high-adhesion emulsion for a cigarette packet film and a preparation method thereof, and the high-adhesion emulsion is composed of the following raw materials: acrylic resin, a cationic emulsifier, an anionic emulsifier, 1, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, an emulsifier, a dispersant, a thickener, a thickener and a solvent. The water-based acrylic resin is prepared from 1, 6-hexanediol diacrylate, a first monomer, a second monomer, a third monomer, a fourth monomer, a fifth monomer, a nonionic emulsifier, a silane coupling agent, an initiator, dimethyl maleic anhydride, ethylene glycol, ethylenediamine, adipic dihydrazide and deionized water. The preparation method is simple and convenient to operate, by strictly controlling the adding time, the reaction time and the reaction temperature of all the raw materials, the reaction rate balance in the early stage and the later stage of the emulsion preparation process can be kept, the conversion rate and the stability of the reaction can be improved, and the prepared emulsion has excellent adhesive force and chemical resistance to a cigarette packet film; and the adhesive force to non-absorbent substrates such as BOPP (biaxially-oriented polypropylene), PP (polypropylene), PVC (polyvinyl chloride), PE (polyethylene) and PET (polyethylene terephthalate) plastic films is excellent.
Description
technical field [0001] The invention relates to the technical field of emulsions, in particular to a high-adhesion emulsion used for cigarette pack films and a preparation method thereof. Background technique [0002] At present, the paint emulsions used for domestic cigarette pack films have disadvantages such as poor adhesion and poor resistance to alcohol scrubbing. Especially when the substrate is BOPP, PP, PE, PET and other plastic films, the above shortcomings are even more prominent. Contents of the invention [0003] The object of the present invention is to provide a high-adhesion emulsion for cigarette wrapping film and its preparation method, which solves the problems of poor adhesion and poor alcohol scrubbing resistance of the emulsion used for cigarette wrapping film in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] In a first aspect, the present invention provides a hig...
