Problems solved by technology

Conductive fillers use conductive carbon fibers, metal fillers, graphite powder, conductive mica, etc. To make the floor coating have good electrical conductivity, a higher filling amount of conductive fillers is required, but too much filling will lead to difficulty in dispersion and self-leveling. Thick coating and settlement, and uneven distribution of conductive fillers will also lead to a decrease in conductivity

Abstract

The invention relates to the technical field of coatings, and particularly discloses a polyurethane flame-retardant anti-static super-wear-resistant finish paint and a preparation method thereof. The polyurethane flame-retardant anti-static super-wear-resistant finishing paint is technically characterized by comprising a component A, a component B and a component C which are independently stored and mixed during use, the component A is an isocyanate curing agent; the component B is prepared from the following raw materials in parts by weight: 60 to 75 parts of polyurethane color paste, 9 to 12 parts of an ester diluent, 1 to 2 parts of a dispersing agent BYK110, 1 to 2 parts of a flatting agent BYK354, 1 to 2 parts of a wetting agent BYK306, 0.2 to 0.5 part of a catalyst, 2 to 6 parts of a flame retardant, 0.5 to 1 part of an anti-settling agent and 1.5 to 2 parts of a conductive agent. The conductive agent is a mixture composed of conductive carbon black, single-walled carbon nanotubes and conductive carbon fibers according to a weight ratio of 1: 2: 1; and the component C is white corundum. The polyurethane finish paint prepared by the invention has excellent antistatic property, flame retardant property and super wear resistance.

Description

technical field [0001] The application relates to the technical field of coatings, more specifically, it relates to a polyurethane flame-retardant antistatic super wear-resistant topcoat and a preparation method thereof. Background technique [0002] Polyurethane topcoat is a two-component polyurethane anti-corrosion topcoat composed of synthetic resin as base material, pigment and curing agent. Polyurethane topcoat has good chemical resistance and water resistance, and the formed paint film is tough and glossy, and is widely used on floors and automobile surfaces. [0003] Used as a floor coating, because the floor is often subject to friction, it is easy to accumulate a large amount of static electricity, which hinders the production process and affects product quality. In severe cases, it will cause fires, explosions and other accidents. The harm of static electricity has been widely used in high-tech industries such as electronics, microelectronics, communications, prec...
