Abstract

The invention relates to an acrylate copolymer emulsion paper-plastic composite adhesive which is prepared from the following raw materials in percentage by weight: 16-37% of butyl acrylate, 8-16% of acrylic acid, 5-11% of methyl methacrylate, 3-8% of acrylonitrile, 1-5% of itaconic acid, 0.1-0.3% of sodium hydroxide, 0.4-0.6% of initiator, 0.1-2% of composite emulsifier, 0.05-0.1% of ammonia water, 0.05-0.1% of defoaming agent, 2-6% of stabilizer and 15-64% of deionized water. The invention also relates to a preparation method of the acrylate copolymer emulsion paper-plastic composite adhesive. The invention has the advantages of abundant raw material sources, low synthesis cost and simple and stable production technique; and the prepared acrylate copolymer emulsion paper-plastic composite adhesive has the advantages of small and uniform particles, high drying rate and favorable storage stability, and is suitable for compounding paper-base presswork and plastics.

Description

technical field [0001] The invention relates to an acrylic ester copolymer emulsion paper-plastic composite glue and a manufacturing method thereof, belonging to the field of new polymer materials. Background technique [0002] Paper-plastic composite is a layer of plastic film on the surface of paper-based printed matter, which is a commonly used composite material in the printing industry. As an intermediate link between the two, the paper-plastic composite adhesive requires good adhesion to non-polar, low-surface-energy plastic film surfaces and polar paper surfaces; it also needs to have good affinity for ink. At present, there are three main types of paper-plastic composite adhesives on the market: solvent-based, emulsion-based, and pre-coated (hot-melt) types. Solvent adhesives often produce pollution and flammability problems during production, and are restricted by strict environmental protection regulations; while pre-coated films (hot-melt type) consume more power...
