Abstract

The invention relates to a preparation method of an emulsion type polyacrylate pressure-sensitive adhesive for a reflecting film. Hard monomers (5-15 parts of vinyl acetate and 5-15 parts of methyl methacrylate) and soft monomers (30-50 parts of ethylhexyl acrylate and 10-30 parts of ethyl acrylate) are subjected to quaternary monomer copolymerization, and consequently, the bonding strength of the pressure-sensitive adhesive is improved obviously. In addition, 0.3-1 part of lauryl sodium sulfate and 1-3 parts of sodium allyloxyhydroxypropyl sulfonate are taken as emulsifying agents; a substance with a surfactant is polymerized to a macromolecular chain to take the place of a part of the micromolecular emulsifying agent lauryl sodium sulfate, and therefore, the aging resistance and the water resistance of the pressure-sensitive adhesive are improved. The emulsion type pressure-sensitive adhesive prepared by use of the preparation method is high in permanent adhesion, high in peel strength, and high in combination properties such as aging resistance, high temperature resistance, water resistance and acid rain resistance, and capable of meeting the requirement on long-term use of the reflecting film. In addition, the preparation method is simple in process, free from environment pollution, low in cost, and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of light-emitting films, in particular to a method for preparing an emulsion-type polyacrylate pressure-sensitive adhesive that can be used for reflective films. Background technique [0002] Polyacrylate pressure-sensitive adhesive materials have a wide range of sources, good heat resistance and weather resistance, UV and chemical resistance, excellent hydrolysis resistance, strong polarity, and can bond various materials. It has a wide range of uses, moderate cost, and can be used outdoors. Traditional polyacrylate pressure-sensitive adhesives are solvent-based, but as people pay more and more attention to environmental protection, environmentally friendly products have attracted more and more attention. Emulsion-type adhesives are non-toxic, harmless, and environmentally friendly. Non-flammable and explosive, low production cost, easy to use and other advantages have become an important trend in the research and d...
