Description

technical field [0001] The invention relates to a flame-retardant coating and a preparation method thereof. Background technique [0002] Today, traditional wall insulation materials generally include phenolic resin synthetic materials, polyurethane materials, glass fiber materials, aluminum silicate rock wool, mineral wool, rubber and plastic, cork, perlite, etc. The construction is cumbersome, the overall thickness, poor water resistance, poor flame retardancy and other shortcomings. With the development of my country's construction industry, the importance of energy saving in houses has become increasingly prominent. As the first barrier of the outermost layer of houses, the comprehensive long-term protection performance of exterior wall coatings is particularly important. Ordinary exterior wall coatings will absorb the infrared rays in sunlight and convert them into heat energy, causing the temperature of the coating to rise. The temperature rises. From a theoretical ...
