Abstract

The invention provides an environmentally-friendly aqueous spray paint liquid, a propellent, an aerosol coated environmentally-friendly aqueous spray paint and a preparation method of the paint. The liquid comprises, by weight, 30-45 parts of aqueous resin, 5-15 parts of a pigment, 15-30 parts of a cosolvent, 20-35 parts of water and 0.5-2 parts of an assistant. The environmentally-friendly aqueous spray paint liquid adopts an aqueous resin system, so a whole paint film has a good hydrophobic and oleophobic effect, and improvement of the quality of spray paint products is facilitated; water is used to substitute parts of a solvent, so the VOC is reduced, and environmental protection is realized; and the produced environmentally-friendly aqueous spray paint has good sprayability and a high spray rate, and a film formed by the paint has high fullness, excellent hardness, adhesion, glossiness, flexibility and impact resistance, and has abundant and gorgeous colors, excellent decorative effect, good ageing resistance, and extremely good antirust and protection functions.

Description

technical field [0001] The invention belongs to the field of new material coating compositions, and relates to a water-based self-spray paint with low volatile organic matter, in particular to an environment-friendly water-based self-spray paint comprising an environment-friendly water-based self-spray paint liquid material, a propellant and an aerosol-type packaging material. its preparation method. Background technique [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value rate. It can not only decorate the surface of buildings, machinery, etc., but also has the function of preventing the surface from rusting and prolonging the service life. With the continuous development of science and technology, coatings have gradually become a kind of fine chemical products with strong specialization and strong functions. [0003] Self-spray paint, that is, aerosol paint, is usually composed of aerosol cans, aeroso...
