Abstract

The invention discloses a fullerene-modified fireproof and heat-insulating coating material and a preparation method thereof, belonging to the technical field of coatings. The fire-proof and heat-insulating coating material is a water-based environmentally friendly coating, which includes the following raw materials in parts by weight: 15-42 parts of resin emulsion, 14-51 parts of pigments and fillers, 3-11 parts of additives, 0.3-5 parts of carbon fiber, rich 0.02-4 parts of leene, 3-12 parts of nano-hollow porous thermal insulation filler, 1-10 parts of fireproofing agent, and 16-50 parts of deionized water. The coating material prepared by the invention has the functions of fire prevention, heat insulation and anticorrosion at the same time, which avoids the need to repeatedly coat different coatings on the surface of equipment or buildings, and also avoids the need to consider the repellency between different coatings and the difference in construction technology It can solve the problems of poor anticorrosion effect of traditional thermal insulation coatings, so it can be widely used in the external surface spraying of external walls of civil buildings, industrial equipment, storage tanks and pipelines.

Description

Technical field [0001] The present invention relates to the field of coating materials, in particular a fullerene modified fire insulation coating material and a preparation method thereof. Background technique [0002] The surface temperature of various finished oil storage tanks and tanker cars rapidly increases, and chemicals stored inside also have a safety hazard with significant temperature rise. For example, chemical storage tanks, the respiratory effect will have a respiratory effect in the past three decades, and my country's economy has continued to develop rapidly, causing attention around the world. With the increasing depletion of global petrochemical energy, how to maintain the rapid sustained development of the economy under a limited energy supply has become a serious challenge for my country. Especially in the hot summer, how to achieve energy conservation and emission reduction in industrial and civilian areas has become the direction in the whole society. [00...
