Abstract

The invention discloses an airgel thermal insulation coating and a preparation method thereof. It is prepared according to the following components by weight: aldehyde and ketone resin 40wt%-60wt%, activated carbon 20wt%-40%, nano silicon dioxide 10wt%-15wt%, airgel 5wt%-10wt%, dispersant 2wt%. The prepared airgel thermal insulation coating has good thermal insulation and air purification effects, and is especially suitable for heat insulation and anticorrosion treatment of the inner surfaces of vehicles and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an airgel thermal insulation coating and a preparation method thereof. Background technique [0002] In daily life and industrial production, metal components are widely used in vehicles, petrochemical storage tanks, bridges, ships and other fields. Thermal insulation through coating can effectively prolong the service life of metal components. [0003] At present, there are many kinds of thermal insulation coatings on the market, and all kinds of coatings can play a good role in thermal insulation. However, unlike other components, metal components have higher functional requirements for coatings. Moreover, due to the low adhesion and insufficient heat resistance of the thermal insulation coating, it is relatively difficult to insulate metal equipment. [0004] At the same time, reducing energy consumption and reducing environmental pollution are also particularly important ...
