Flame-retardant reflective heat-insulating paint and preparation technique thereof

Abstract

The invention discloses a flame-retardant reflective heat-insulating paint and a preparation technique thereof. The flame-retardant reflective heat-insulating paint comprises the following components in parts by weight: 25-35 parts of acrylic emulsion, 10-25 parts of butyl acetate, 5-15 parts of halogen-free flame retardant, 2-12 parts of heat-reflection heat-insulating powder, 10-20 parts of hollow microbead, 1-8 parts of coupling agent, 2-7 parts of leveling agent, 3-9 parts of film-forming assistant and 20-30 parts of deionized water. The flame-retardant reflective heat-insulating paint is free of halogens, and thus, is nontoxic and environment-friendly. The flame-retardant reflective heat-insulating paint has the advantages of high thermal resistance, high reflectivity and favorable radiant heat transfer performance, can simultaneously have the functions of heat insulation and flame retardancy, has more balanced flame retardancy and heat-insulating property, can implement better flame-retardant and heat-insulating effects, and is suitable for the field of decoration of dwelling houses, school buildings, hotel buildings and other buildings.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a flame-retardant reflective heat-insulating coating and a preparation process thereof. Background technique [0002] Reflective heat insulation coating is a new type of energy-saving material developed in recent years. By effectively reflecting, blocking, and radiating the energy of sunlight, it can significantly reduce the temperature of building exterior walls, roofs, and indoors, thereby effectively reducing the temperature of refrigeration equipment such as air conditioners. Energy consumption at high temperature. Therefore, reflective thermal insulation coatings can not only improve the working environment, but also save a lot of energy. [0003] With people's requirements for more functions of coatings, single-function coatings have become less and less suitable for the needs of society. Flame-retardant reflective heat-insulating coating is a multi-functional coating with both fl...

Problems solved by technology

[0004] However, although there are various flame-retardant and heat-insulating coatings in the prior art, these coatings either have unsatisfactory flame-retardant effects, poor heat-insulating properties, or contain halogens, which do not meet environmental protection requirements.
