Water type colorful coating

Abstract

The invention discloses a water type colorful coating which is prepared from the following raw materials in parts by weight: 100 parts of hydroxyethyl cellulose, 15-25 parts of isopropanol, 20-30 parts of sodium hydroxide, 40-50 parts of xylene, 10-20 parts of sodium carboxymethylcellulose, 5-15 parts of lead naphthenate, 80-90 parts of deionized water, 15-35 parts of cobalt naphthenate, 10-20 parts of pigment, 25-35 parts of modified bentonite, 20-40 parts of sodium polystyrenesulfonate, 10-30 parts of talcum powder, 4-10 parts of plasticizer, 30-40 parts of titanium dioxide, 10-20 parts of naphthalene sulfonic acid and 20-30 parts of zinc phosphate. The product is bright and smooth in color, a coating film is resistant to scrubbing of 12000-13000 times without exposing a substrate, the dispersibility is good, no bobbles are caused and no powder drops off when the product is soaked in water of 20 DEG C for 40-60 days, the consumption of a reciprocating testing machine of 1000 times is 0.004-0.006g / cm<2>, the coating film is bright in color and good in decoration effect after being stored for 6-10 months at 25 DEG C, and thus the coating can be widely produced to constantly replace a conventional material.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a water-based colorful coating. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives, viscous liquid prepared with organic solvent or sodium carboxymethyl cellulose. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." The material coated on ...
