Heat-insulation coating and production method thereof

Abstract

The invention belongs to the technical field of a coating and a preparation method thereof, and discloses a heat-insulation coating and a production method of the heat-insulation coating. The main technical characteristics are that the heat-insulation coating contains the following materials according to parts by weigh: 100kg of purified water, 38-42kg of polyvinyl alcohol, 95-108kg of nano ceramic tiny beads of more than 2000 meshes, 18-25kg of silicon and aluminum fiber, 28-34kg of heavy calcium carbonate of more than 1000 meshes, 13-16kg of light calcium carbonate of more than 1000 meshes, 1-2kg of flowage assistant agent, 1-2kg of adhesion improver, 0.5-1.5kg of defoamer, and 2-3kg of scratch-resisting agent. By inhibiting and shielding the radiant heat and the heat energy conduction of infrared rays and inhibiting loss of heat radiation and heat energy of high-temperature objects the heat insulation effect can be achieved. Furthermore, cold insulation to low-temperature objects can be realized, and cold energy loss caused by the radiant heat of the environment can be inhibited so as to prevent cold energy loss.

Description

technical field [0001] The invention belongs to the technical field of coatings and preparation methods thereof, and in particular relates to thermal insulation coatings and production methods thereof. Background technique [0002] For indoor and outdoor pipelines, equipment and equipment components of windshields, especially for special-shaped pipelines and equipment insulation, traditional insulation materials are not easy to solve, and insulation coatings are used for insulation. The thermal insulation coatings currently used have the following disadvantages: first, the application range is small, and the thermal insulation performance is poor when the temperature is higher than 150°C and lower than -20°C; second, the waterproof performance is poor, and the service life is short outdoors; third, the anti-corrosion performance Poor, under the corrosion of acid environment or alkaline environment, it is prone to peeling and peeling; Fourth, the insulation coefficient is low...

Problems solved by technology

The thermal insulation coatings currently used have the following disadvantages: first, the application range is small, and the thermal insulation performance is poor when the temperature is higher than 150°C and lower than -20°C; second, the waterproof performance is poor, and the service life is short outdoors; third, the anti-corrosion performance Poor, under the corrosion of acid environment or alkaline environment, it is prone to peeling and peeling; Fourth, the insulation coefficient is low at high temperature; Fifth, the wear resistance and impact resistance are poor, so it cannot be used on the equipment parts of the windshield Sixth, poor stability, under normal and high temperature conditions, it is easy to produce peculiar smell, seventh, poor flame retardancy and adhesion; eighth, poor stretch resistance, when equipment or pipelines expand with heat and contract with cold, the coating is easy to fall off
