Abstract
The invention discloses an aerogel thermal-insulation damping coating. The aerogel thermal-insulation damping coating is prepared from the following components in parts by weight: 28 to 38 parts of anacrylic dispersion, 1 to 2 parts of a modified acrylic copolymer, 20 to 28 parts of an acrylic emulsion, 0.1 to 0.9 part of an adhesion promoter, 1 to 3 parts of a dispersing agent, 1 to 2 parts of ananometer thermal-insulation filler and 12 to 25 parts of macromolecular polysaccharide. The aerogel thermal-insulation damping coating can prevent equipment operators from being scalded by heat, improve a work environment, reduce the energy loss and cost of equipment, enhance energy-saving effect and bring economic benefits to customers, has excellent scald resistance and corrosion resistance, hydrophobicity and anti-condensation and anti-icing performance, is high in heat insulation efficiency, reduced in energy consumption, friendly to environment, easy to construct, not limited by the form of a base material, convenient for equipment overhauling, high in volume solid content, low in VOC and capable of being widely popularized and used.
Description
technical field [0001] The invention relates to the technical field of airgel, in particular to an airgel heat-insulating and damping coating. Background technique [0002] LASD airgel thermal insulation coating heat series products are a kind of airgel water-based thermal insulation slurry, which can be directly used on the surface of industrial storage tanks, reaction equipment, pipelines, 0.035-0.040 new energy vehicles, rail transit components, etc. Provide heat insulation protection. The product is made of high temperature resistant and corrosion resistant new heat insulation material suspended in high temperature resistant resin and other additives, with excellent heat insulation performance; [0003] However, traditional thermal insulation materials have certain disadvantages. Limited by the base material, there is a gap with the base material, and there will be heat loss. Foaming on site, molding into the mold, and seamless combination. It is not waterproof itself, ...
