Abstract

The invention discloses a wearproof antifouling two-component polyurethane paint and a preparation method thereof. The wearproof antifouling two-component polyurethane paint is prepared from the following raw materials by weight: 70-80 parts of polypropylene oxide glycol, 140-150 parts of hexamethylene diisocyanate, 4-6 parts of sorbitol, 2-4 parts of ethanolamine, 7-9 parts of acrylic ester, 5-6 parts of dipropylene glycol dibenzoate, and 2-3 parts of tert-butyl peroxypivalate, etc. According to the invention, polyurethane, acrylic ester and the like are adopted for cooperation to serve as film-forming matters, so that the wearproof antifouling two-component polyurethane paint has good film-forming characteristics. The added sub-white corundum fine powder, white graphite, aluminum titanate and other raw materials can be evenly and stably dispersed in the paint under the action of polypropylene glycol and sodium methylene dinaphthalene sulfonate to enhance the wear resistance of the paint. The added dipropylene glycol dibenzoate, perfluorooctyl triethoxysilane and other raw materials can improve the antifouling and water resistant performance of the paint.

Description

technical field [0001] The invention relates to a coating, in particular to a wear-resistant and antifouling two-component polyurethane coating and a preparation method thereof. Background technique [0002] Polyurethane coatings are currently the most common type of coatings, which can be divided into two-component polyurethane coatings and one-component polyurethane coatings. Two-component polyurethane coatings are generally composed of isocyanate prepolymers and hydroxyl resins, commonly known as curing agent components and main agent components. There are many varieties of this type of coating, and the application range is also very wide. According to the difference of the hydroxyl group-containing components, it can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane and other varieties. Generally, it has good mechanical properties, high solid content, and good performance in all aspects. It is a ...
