Abstract

The invention relates to a preparation method of aqueous vinylidene chloride glue used in a high-barrier plastic film. The preparation method comprises the following steps: taking cheap and available vinylidene chloride as a main comonomer, and selecting the vinylidene chloride, polymerizable functional monomer, acrylic monomer and part of unsaturated fatty acid to be copolymerized in the presence of various emulsifiers by seeded semi-continuous emulsion polymerization to obtain an aqueous vinylidene chloride adhesive with good property. When the base glue is applied to the bottom layer of the plastic film (polypropylene, polyethylene, polyester and polyamide), the base glue has the advantages of good wettabilityand strong cohesive force, and the base glue is especially suitable for replacing a polyurethane adhesive as the base glue when coating the high-barrier plastic film.

Description

technical field [0001] The invention relates to a water-based vinylidene chloride adhesive used as a primer when coating a high-barrier plastic film. Background technique [0002] Adhesives for plastic films are usually based on solvent-based polyurethane adhesives. In recent years, people's attention has focused on the toxicity, flammability and pollution of the product. It is hoped that the adhesive used is a non-toxic, non-flammable and non-polluting green product dispersed in water. Due to the emphasis on environmental protection and personal health, a lot of research has been carried out on water-based adhesives at home and abroad, but the research mainly focuses on acrylic water-based adhesives. [0003] Patent CN 1223618C discloses the preparation and coating method of latex paint for disposable paper tableware. Patent CN1986583A relates to a special water-based PVDC latex for coating on special cloth and its preparation method. Patent CN 1294326C discloses a beverag...
