Abstract

The invention provides a polyvinylidene chloride-acrylate copolymer emulsion for a water-based metal anti-corrosion coating and a synthetic method thereof. The copolymer emulsion is prepared from, byweight, 40-50 parts of mixed monomer, 0.2-0.25 part of an initiator and 0.4-0.5 part of emulsifier, wherein the mixed monomer is prepared from 15% of acrylic ester, 5% of acrylic acid and 80% of vinylidene chloride, the initiator is prepared from potassium persulfate, and the emulsifier is prepared from 20% of sodium lauryl sulfate and 80% of 1-allyl-2-sodium hydroxy alkanesulfonate. The preparedpolyvinylidene chloride-acrylate copolymer emulsion for the water-based metal anti-corrosion coating is high in toughness and adhesive force, and good in storage stability, salt spray resistance, corrosion resistance and other comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and relates to a metal anti-corrosion coating, in particular to a polyvinylidene chloride-acrylate copolymer emulsion for water-based metal anti-corrosion coatings and a synthesis method thereof. Background technique [0002] Water-based coatings were first widely used in the field of construction, and then gradually promoted for industrial corrosion protection of steel structures including marine engineering. Compared with traditional coatings, water-based anti-corrosion coatings have high production efficiency and excellent material properties, and have achieved "sustainable development and zero emissions", which has become one of the development directions of the coatings industry today. Water-based coatings use water as a solvent or thinner, are non-toxic, odorless, non-flammable, have no danger of fire and explosion, and are not harmful to human health. [0003] In recent ye...
