Polymer water-retention coating for automobile parts

Abstract

A polymer water-retention coating for automobile parts consists of the following raw material components in parts: 30-60 parts of water-soluble acrylic resin, 10-15 parts of polyurethane resin, 3-8 parts of a stabilizer, 1-4 parts of a deforming agent, 20-40 parts of pentaerythritol, 30-40 parts of phthalic anhydride, 30-60 parts of maleic anhydride, 6-10 parts of sodium lauryl ether sulfate, 12-20 parts of cocamidopropyl betaine, 10-20 parts of sodium sulfate, 10-15 parts of nonafluorobutanesulfonyl fluoride, 2-18 parts of triethanolamine, 1-5 parts of citric acid, 5-15 parts of sodium petroleum sulfonate, 2-4 parts of fatty alcohol polyoxyethylene ether, 2-4 parts of p-nitrobenzoic acid, 1-2 parts of sodium tetraborate, 2-3 parts of dimethylmaleic anhydride and a certain amount of deionized water. The polymer water-retention coating film for automobile parts provided by the invention has high film fullness, good distinctness of image and scratch resistance, low toxicity and low price.

Description

technical field [0001] The invention belongs to the technical field of topcoats for auto parts, and in particular relates to a polymeric water-retaining coating for auto parts. Background technique [0002] At present, a large number of special coatings used in automobile parts such as axles, wheel hubs, radiators, shock absorbers, water tanks and oil tanks are all solvent-based coatings. Most of these paints use flammable and explosive toluene, xylene, solvent naphtha, etc. as diluents, which not only have pollution problems, but also pose potential safety hazards during construction. In the context of ecological protection, energy saving and emission reduction, and the development of environmentally friendly coatings, water-based auto parts special paints have become a new field that people and paint manufacturers are increasingly concerned about. Non-toxic, non-irritating, non-polluting, non-volatile harmful substances, non-flammable and non-explosive, safe and convenien...
