Monocomponent self-cross-linking epoxy acrylic acid composite emulsion , its preparation method and uses

Abstract

The invention provides a monocomponent self-cross-linking epoxy acrylic acid composite emulsion , its preparation method and uses, wherein the emulsion comprises the constituents of epoxy resin, (methyl) acrylic ester, alkenyl carboxyl acid, ethenyl aromatic compound, silicane coupling agent, initiating agent, emulsifying agent, pH regulator, neutralization agent and water. The composite emulsion is prepared through the emulsion polymerization process and by using epoxy propylene acid composite emulsion as the base.

Description

technical field

[0001] The invention relates to the field of composite polymer materials, in particular to a single-component self-crosslinking epoxy-acrylic composite emulsion and its preparation method and application. Background technique

[0002] Epoxy resin has excellent bonding performance, corrosion resistance, electrical insulation performance, chemical resistance and low shrinkage, and is mainly used in the fields of anti-corrosion coatings, adhesives and composite materials, but it has a brittle texture and heat resistance. It has disadvantages such as poor performance, impact resistance, fatigue resistance, crack resistance and poor resistance to heat and humidity. Acrylic resin has good weather resistance, acid and alkali resistance and light resistance, and is mainly used in the fields of coatings, fabric treatment and adhesives, but it has disadvantages such as poor water resistance and cold resistance, brittle at low temperature, and s...
