Problems solved by technology

[0004] At present, water-based acrylic coatings have problems such as short anti-corrosion period, easy to flash rust after coating, poor acid and weather resistance, poor hardness and stability, etc.
At the same time, acrylic paint is an organic substance, which is flammable in case of fire after film formation, produces thick smoke and a large number of harmful substances, which affects its application range, so it is very necessary to modify its flame retardancy

Abstract

The invention relates to a polystyrene microsphere modified acrylic waterborne industrial paint, which is composed of polystyrene microsphere modified acrylic waterborne resin, a cosolvent, a substrate modifier, a nano-functional material, pigment and filler, assistants and water. Specifically, the nano-functional material is nano-SiO2, nano-ZnO, nano-TiO2, nano-Al2O3, nano-SnO2, nano-boron nitride, potassium titanate whisker, carbon nanotubes or graphene; and the polystyrene microsphere modified acrylic waterborne resin is synthesized by using allyl polystyrene microsphere as the functional monomer and then carrying out ATRP free radical polymerization reaction. The polystyrene microsphere modified acrylic waterborne industrial paint prepared according to the invention has excellent adhesion, water resistance, corrosion resistance, wear resistance, heat and humidity resistance, salt fog resistance, aging resistance, flash rust resistance, rust and corrosion resistance, and crack resistance.

Description

technical field [0001] The invention relates to a modified acrylic resin water-based coating, in particular to a polystyrene microsphere-modified acrylic water-based industrial coating, which belongs to the technical field of water-based functional coatings. Background technique [0002] Coating is an indispensable material for daily production and protection of infrastructure. It is widely used in buildings, various hardware, decoration of industrial products, machinery, vehicles, ships, aircraft, instruments and other fields. Acrylic resin coatings have the advantages of cheap raw materials, good wettability to pigments, etc., and have good construction properties, and have always played an important role in the field of coatings. However, traditional acrylic resin paints contain a large amount of organic solvents, which have a serious impact on the human body and the ecological environment. [0003] With the enhancement of people's awareness of environmental protection, ...
