Abstract

The invention discloses an antistatic polyurethane paint and a preparation method thereof. The antistatic polyurethane paint is prepared from the following raw materials by weight: 45-55 parts of a waterborne polyurethane emulsion, 30-40 parts of waterborne acrylic resin, 1-5 parts of sodium monododecyl phosphate, 0.5-2.5 parts of octadecyl trimethyl ammonium chloride, 5-15 parts of silicon dioxide, 0.3-0.9 part of dimethicone, 15-25 parts of ethanol, 10-50 parts of water, 1-5 parts of an inorganic antibacterial agent, and 1-5 parts of a dispersant. According to the antistatic polyurethane paint and the preparation method thereof, through reasonable proportioning, the dispersant and inorganic antibacterial agent variety and dosage suitable for the antistatic polyurethane paint are selected optimally, so that the antistatic polyurethane paint has improved antistatic property and antibacterial property, and has the advantages of excellent physical and mechanical properties, temperature resistance, weatherability, chemical resistance and excellent wear resistance, convenient construction, and high efficiency.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antistatic 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 topcoat paint is generally composed of isocyanate prepolymers (also known as low molecular carbamate ester polymers) 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, they have good mechanical properties, high solid con...
