Problems solved by technology

[0002] Pure acrylic resin has no adhesion to polyolefin and polyester film, so its application is limited. Generally, it is modified by polyurethane and silicone. There are also attempts to modify epoxy resin, but it contains organic solvents. This modification The disadvantages are high viscosity, inconvenient use and solvent residue; and these organic solvents are generally ethyl acetate, benzene, toluene, ethanol or butanol, the use of these solvents will cause damage to people and the environment

Abstract

The invention relates to an epoxy modified acrylic resin emulsion and a preparation method thereof. Raw materials of the emulsion are proportioned as follows: 40-100 parts by weight of acrylic ester monomer; 80-100 parts by weight of methacrylate monomer; 1-10 parts by weight of acrylic hydroxy ester monomer; 2-80 parts by weight of epoxy resin; 2-10 parts by weight of a nonionic surfactant; 2-10 parts by weight of an anionic surfactant; 0.2-1 part by weight of an initiator; 0.2-1 part by weight of a reducing agent; and 200 parts by weight of water. The epoxy modified acrylic resin emulsion has good adhesive strength to BOPP, PET, VMPET, PE, CPP and aluminum foil, and no solvent is needed during the adhesion process. The epoxy modified acrylic resin emulsion is safe and environmentally friendly as a good adhesive resin emulsion for plastic-plastic composites and paper-plastic composites.

Description

technical field [0001] The invention relates to an acrylate emulsion and a preparation method, in particular to an epoxy-modified acrylic resin emulsion and a preparation method for bonding various substrates. Background technique [0002] Pure acrylic resin has no adhesion to polyolefin and polyester film, so its application is limited. Generally, it is modified by polyurethane and silicone. There are also attempts to modify epoxy resin, but it contains organic solvents. This modification The disadvantages are high viscosity, inconvenient use and solvent residue; and these organic solvents are generally ethyl acetate, benzene, toluene, ethanol or butanol, and the use of these solvents will cause damage to people and the environment. [0003] Therefore, providing an acrylic resin emulsion with environmental protection, superior performance and simple preparation process has become an urgent technical problem in this technical field.
