Problems solved by technology

Patent CN101205435A discloses a solar heat reflective heat-insulating coating, which is formed by blending two parts of the surface layer and the bottom layer. The coating contains organic solvents and a small amount of plasticizer, which is not conducive to environmental protection when used on a large scale
The professional application of heat-insulating coatings is still immature, and active-cooling professional heat-insulating coatings with excellent heat-insulating performance, such as heat-insulating coatings specially used on metal surfaces such as open-air chemical equipment and oil pipelines, urgently need to be developed and popularized.

Abstract

The invention relates to a heat-insulating coating and a preparation method thereof. The coating is characterized in that the coating is a mixture composed of the following substances in parts by weight: 30-80 parts of a component A, 20-60 parts of a component B, 15-40 parts of rutile titanium dioxide, 10-25 parts of fly ash floating beads, 1-10 parts of vacuum ceramic micro-spheres, 1-5 parts of an infrared radiation substance, 0.1-1 part of a flash rusting resistant agent, 0.1-0.8 part of a silane coupling agent, and 0.2-2 parts of a thickener, wherein the component A is a mixture of 3-10 parts of polyethylene glycol 800, 1-8 parts of polyethylene glycol 1000, 1-6 parts of paraffin, 15-35 parts of expanded perlite, 5-15 parts of diatomite, 0.1-0.5 part of JFC, 0.1-0.6 part of sodium dodecyl sulfate, 0.1-0.3 part of OP-10, and 40-60 parts of deionized water; and the component B is a mixture of 20-50 parts of a silicone-acrylic emulsion, 10-30 parts of a polyurethane emulsion, 5-20 parts of a fluororesin emulsion, 0.1-0.3 part of a film forming auxiliary agent, 0.1-0.8 part of a rheological agent and 10-30 parts of deionized water. Based on the coating, the preparation method comprises three process steps: component A preparation, component B preparation and finally, coating preparation.

Description

technical field [0001] The invention relates to the technical field of heat-insulating coatings, and more specifically relates to a heat-insulating coating specially used on various metal surfaces such as oil pipelines, oil storage tanks, and outdoor industrial cooling equipment and other surfaces and a preparation method thereof. Background technique [0002] The sun radiates huge energy to the earth's surface all the time. Objects exposed to the sun's direct rays often cause the surface temperature to rise excessively due to the gradual accumulation of heat, which brings hidden dangers to safe production. In order to reduce the temperature of these objects The surface temperature wastes a lot of energy. Especially for some petrochemical containers, open-air reactors and oil pipelines, high temperature will bring them potential accident hazards and excessive energy waste. In summer (especially in southern my country), due to strong solar radiation, the temperature of the...
