Abstract

The invention relates to the technical field of water-based coatings, and provides an emulsion for a chloropropyl metal protective paint, which comprises the following components in parts by weight: 10-60 parts of deionized water, 0.1-1 part of a pH buffer agent, 0.1-1 part of an anionic emulsifier, 0-1 part of iso-tridecanol polyoxyethylene phosphoric acid, 20-60 parts of a polyvinyl chloride emulsion, 25-45 parts of a main monomer, 0.1-1 part of a hydrophilic functional monomer and 0.1-1 part of a carboxyl monomer. The invention relates to an anti-corrosion coating which is prepared from the following components in parts by weight: 0.1 to 1 part of phosphate monomer, 0.1 to 1 part of initiator, 0.02 to 0.2 part of silane coupling agent, 0.01 to 0.1 part of post-deoxidizer, 0.01 to 0.1 part of post-dereductant, 0.02 to 1 part of defoaming agent, 0.01 to 0.5 part of anti-corrosion bactericide, 0.2 to 1 part of pH regulator and 0.1 to 1 part of nonionic surfactant. Through the technical scheme, the problem of low salt fog resistance of the emulsion type metal protective paint in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to an emulsion for metal chloride propylene protective paint and a preparation method and application thereof. Background technique [0002] With the rapid development of my country's environmental protection requirements, especially since the implementation of the paint consumption tax, the development of paint has been greatly restricted, and the consumption of water-based anti-corrosion metal protective paint has increased rapidly. In 2015, the domestic consumption of anti-corrosion metal protective paint was nearly 4 million tons, of which The consumption of various water-based anti-corrosion metal protective paint emulsions is about 1 million tons, of which the consumption of water-based acrylic metal protective paint emulsions is about 150,000 tons. It is estimated that by 2025, the sales volume of the anti-corrosion metal protective paint market will exceed 10 mill...
