Abstract

The invention discloses a water-in-oil type nitrocellulose colorful coating which comprises the following components in parts by weight: 100 parts of nitrocellulose, 5-15 parts of methyl isobutyl methyl acetate, 20-30 parts of titanium dioxide, 40-50 parts of methylbenzene, 10-30 parts of acrylic rubber, 5-25 parts of t-butyl perbenzoate, 80-90 parts of deionized water, 15-25 parts of n-butyl methacrylate, 10-20 parts of pigment, 15-35 parts of hydroxypropyl methacrylate, 25-45 parts of butyl acetate, 20-40 parts of crylic acid tert-butyl ester, 4-10 parts of plasticizer, 35-45 parts of acetone, 10-20 parts of castor oil and 25-35 parts of trimethylolpropane. The coating is uniform after being stirred, the preservation stability of the coating lasts for 8-10 months, the solid content is 25-35%, no blistering or powder drop happens after the coating is soaked in water for 30-40 days, the surface dry time is 0.5-1 hour, no powder drop or blistering happens after the coating is soaked in saturated calcium hydroxide for 10-30 days; the scrub resistance of the coating is 5000-7000 times; therefore, the coating can be widely produced and continuously replace conventional materials.

Description

Technical field [0001] The application belongs to the field of coatings, and particularly relates to a water-in-oil nitrocellulose colorful coating. Background technique [0002] Paint, the traditional Chinese name is paint. 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. It is usually based on resin, oil, or emulsion, with or without pigments, fillers, and Corresponding additives, viscous liquid prepared with organic solvents or acrylic rubber. The authoritative book "Coating Technology" in the Chinese paint industry defines it as follows: "Coating is a material that can be coated on the surface of an object with different construction techniques to form a firm, strong and continuous surface. Solid thin film. The film formed in this way is generally called coating film, also known as paint film or coating. "The material that paints on the surface of an object tha...
