Problems solved by technology

[0004] At present, the fire-proof, reflective and heat-insulating inorganic coatings for external walls on the market mostly use inorganic-organic composite systems, together with a small amount of low-VOC polymer emulsion, which has the advantages of inorganic and organic coatings, but after all, there are organic polymer components, which can only be used To achieve a certain degree of fire resistance, its combustion performance can only be A2 (difficult to burn) stipulated in GB 8624-2006, and it is difficult to meet the requirements of improving the fire resistance to A (non-combustible)

Abstract

The invention relates to an external wall fireproof reflective heat-insulation inorganic coating material, which comprises a base material, a filler, an auxiliary agent and water, wherein the base material comprises, by weight, 15-20 parts of lithium silicate, 15-20 parts of nano long hydrocarbonyl silane modified silica sol, 4-6 parts of nano hydroxyl magnesium silicate and 2-5 parts of an aluminum dihydrogen phosphate aqueous solution, and the filler is prepared from the following components in parts by weight: 20 to 25 parts of IR-1000 near-infrared reflective titanium dioxide, 10 to 15 parts of wollastonite powder, 10 to 15 parts of talcum powder and 1 to 5 parts of nano titanium dioxide. The invention also discloses a preparation method of the external wall fireproof reflective heat-insulation inorganic coating material. The coating material has the advantages of being free of VOC, not prone to combustion, good in high temperature resistance, capable of achieving reflective heat-insulation, not prone to corrosion and resistant to mould.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fire-resistant reflective heat-insulating inorganic coating for exterior walls and a preparation method thereof. Background technique [0002] With the intensification of environmental pollution, countries around the world have limited the content of volatile organic compounds (VOC) in coatings, so inorganic coatings have become one of the development discoveries of coatings due to their environmental protection performance. [0003] In the late 1980s, the initial inorganic coatings gradually appeared in our country. In recent years, various high-performance inorganic coatings have been developed. However, the development of inorganic coatings for fire prevention, reflection and heat insulation on external walls is not particularly ideal. [0004] At present, the fire-proof, reflective and heat-insulating inorganic coatings for external walls on the market mostly use inorganic...
