Abstract

The invention discloses a fullerene modified fireproof thermal-insulation coating material and a preparation method thereof, and belongs to the technical field of coatings. The fireproof thermal-insulation coating material is a water-based environment-friendly coating and comprises the following raw materials in parts by weight: 15-42 parts of a resin emulsion, 14-51 parts of pigment and filler, 3-11 parts of an auxiliary agent, 0.3-5 parts of carbon fibers, 0.02-4 parts of fullerene, 3-12 parts of nano hollow porous thermal-insulation filler, 1-10 parts of a fire retardant and 16-50 parts ofdeionized water. The coating material prepared by the invention has functions of fire resistance, heat insulation and corrosion resistance, so that the situation that an equipment surface or a building surface needs to be repeatedly coated with different coatings is avoided, and the problem that rejection among different coatings and differences among construction processes are required to be considered is solved; moreover, the problems of poor corrosion resistance and the like of a conventional heat-insulation coating can be solved, so that the coating material provided by the invention can be widely applied to outer surface spraying of civil building outer walls, industrial equipment, storage tanks, pipelines and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fullerene-modified fireproof and heat-insulating coating material and a preparation method thereof. Background technique [0002] The surface temperature of various types of refined oil storage tanks and tank trucks in petrochemical enterprises has risen rapidly, and the chemicals stored inside have also risen significantly, posing safety hazards. For example, chemical storage tanks will have a breathing effect in summer. In the past three decades, my country's economy has continued to develop rapidly, which has attracted worldwide attention. With the depletion of global petrochemical energy, how to maintain rapid and sustainable economic development under the premise of limited energy supply has become a severe challenge for our country. Especially in the hot summer, how to achieve energy saving and emission reduction in industrial and civil fields has become the direction o...
