Waterborne paint

Abstract

The invention discloses waterborne paint. The waterborne paint is prepared from the following raw materials in parts by mass: 20 to 50 parts of water, 2.0 to 6.0 parts of potassium trimethylsilanolate, 0.35 to 0.1 part of dispersing agent, 0.05 to 0.65 part of wetting agent, 20 to 45 parts of titanium dioxide, 8 to 25 parts of filler, 25 to 45 parts of emulsion and 1 to 2 parts of curing agent. As the waterborne paint provided by the invention contains an organic silicone component, adopts ceramic particles and / or chitosan as filler, the adsorption performance of the ceramic particles and the thickening effect of the chitosan are utilized, the precipitation of salt and alkali or the pulverization of a paint film caused by too much filler or inappropriate ratio in the prior art is reduced, the addition of the chitosan also increases the bonding and adhesion between the components, and is conducive to improving film-forming properties and paint film strength; the waterborne paint provided by the invention is a waterborne product, which has a relatively good anti-pollution property, is suitable for production, and better suitable to people's needs.

Description

technical field [0001] The invention relates to the field of paint processing and production, in particular to a water-based paint. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. According to the type of binder in the coating, water-based coatings are divided into two categories: natural water-based coatings of natural substances or minerals (such as potassium silicate) and petrochemical water-based coatings of artificial synthetic resins (such as acrylic resins). Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. When the existing water-based paint is in use, the color of the substrate or the overall color is still uneven after multiple coats, or the coating film is too thin, and salt and a...
