Abstract

The invention provides fire retardant coating which comprises the following components by mass: 80-100 parts of waterborne polyurethane, 10-20 parts of hydroxyethyl methylacrylate, 10-15 parts of acrylic acid-2,4,6,-tribromophenyl, 5-10 parts of hydroxy-propyl acrylate, 2-4 parts of acrylic acid, and 0.3-0.5 part of initiator. The fire retardant coating prepared by the invention has the advantages of high quality and high efficiency, excellent in fire retardant property, and good in finishing and coating properties.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a flame-retardant coating and a preparation method thereof. Background technique [0002] Flame-retardant coatings are the most widely used, most adaptable, and most convenient construction materials in modern engineering, and they have played a huge role in ensuring the safety of buildings. With the improvement of people's living taste, people are more fond of building materials such as wooden structures and steel structures. On the one hand, the flame-retardant coating has a beautiful effect on the above materials, on the other hand, when a fire occurs or is subjected to high temperature, the flame-retardant coating has a good protective effect on wood and steel structures, and is a good flame-retardant and heat-insulating building material. [0003] Water-based polyurethane coating is a kind of coating based on water-based polyurethane resin and dispersed in water level. I...
