Abstract

The invention discloses a flame-retardant antistatic two-component waterborne polyurethane coating and a preparation method thereof. The flame-retardant antistatic two-component waterborne polyurethane coating comprises a component A and a component B, wherein the mass ratio of the component A to the component B is (8:1) to (10:1); the component A is prepared from the following raw materials in parts by weight: 50-70 parts of methyl methacrylate, 30-40 parts of butyl acrylate, 10-14 parts of methacrylic acid, 5-7 parts of sodium dodecyl sulfate, 10-16 parts of polythiophene antistatic liquid, 2-4 parts of composite conductive mica powder, 5-6 parts of ultrafine carbon black, 4-8 parts of an emulsifier, 2-4 parts of potassium persulfate, 6-8 parts of polysiloxane, 10-12 parts of nano calcium carbonate, and 50-60 parts of water; the component B is prepared from the following raw materials in parts by weight: 6-8 parts of waterborne nitrocellulose, 1-3 parts of modified nano-alumina, and 2-4 parts of a surfactant. The flame-retardant antistatic two-component waterborne polyurethane coating disclosed by the invention is high in environmental protection safety, excellent in flame-retardant and antistatic effects, stronger in adhesion and better in water resistance.

Description

technical field [0001] The invention belongs to the field of paint production technology, and in particular relates to a flame-retardant and antistatic two-component water-based polyurethane paint and a preparation method thereof. Background technique [0002] Coating is a supporting engineering material that is coated on the surface of an object and can form a continuous film that is firmly attached. It is widely used in industrial production and people's daily life, and plays an active role in protecting the substrate and beautifying the appearance. With the improvement of environmental protection regulations in various countries and the enhancement of people's awareness of environmental protection, the emissions of volatile organic compounds and harmful air pollutants in traditional solvent-based coatings are increasingly restricted, and the development of low-pollution, high-performance, multi-functional Environmentally friendly water-based coatings have become the main ...
