Abstract

The invention relates to spray type aerogel which is prepared by mixing the following raw materials in parts by mass: 30-40 parts of acrylic resin, 10-20 parts of aerogel powder, 0.5-1.5 parts of a silane coupling agent, 1-3 parts of an anti-settling agent, 10-20 parts of a solvent and 30-40 parts of a propellant. The spray type aerogel further comprises 0.1-5 parts of pigment. The spray type aerogel is good in storage stability and re-dispersibility, strong in filming adhesion and convenient and quick to use, has a very small coefficient of heat conductivity, and can effectively separate heat sensitive elements around a heat source, prolong service lives of the heat sensitive elements, and ensure normal operation of the heat sensitive elements.

Description

technical field [0001] The invention relates to aerogels, in particular to a spray-type aerogel. Background technique [0002] Airgel is a solid form of matter, one of the smallest solids in the world. The density is 3 kilograms per cubic meter. The common airgel is silica airgel, which was first made by American scientist Kistler in 1931 due to a bet with his friends. There are many types of aerogels, including silicon-based, carbon-based, sulfur-based, metal oxide-based, metal-based and so on. Aerogel is a compound word, where aero is an adjective, which means flying, and gel is obviously a gel. Literally a gel that can fly. Any gel of any substance can be called an aerogel as long as it can keep its shape basically unchanged after the internal solvent is removed after drying, and the product has high porosity and low density. At present, airgel heat insulation materials commonly used in the market are mostly airgel felts, which are thicker and cannot meet the needs o...
