Abstract

The invention discloses waterborne polyurethane coating and a preparation process thereof. The waterborne polyurethane coating is prepared from modified waterborne polyurethane, an expansive fire-retardant system, a flame retardant synergist, water, filler, a dispersing agent, an antifoaming agent, a thickening agent, a curing agent, a mildew-proof bactericide, a coalescing agent and a penetrating agent. The preparation process is simple, feasible and low in preparation cost, and the coating prepared according to the method is great in flame retardation effect, nontoxic and free of environment pollution.

Description

technical field [0001] The invention belongs to the field of paint preparation, in particular to a water-based polyurethane paint and a preparation method thereof. Background technique [0002] As a new type of environmentally friendly material, water-based polyurethane has been widely used in textiles, printing and dyeing, leather processing, wood processing and architectural coatings. However, the materials involved in these fields are basically flammable materials, and there are potential fire hazards. Therefore, it is necessary to carry out flame retardant treatment before using these materials. For the purpose of protecting people's lives and properties and reducing fire risks, it is necessary to develop new environmentally friendly flame-retardant materials and apply them in actual production and life. [0003] As a common green and environmentally friendly textile finishing agent, water-based polyurethane coating agent is a high-molecular organic material and also a ...
