Abstract

The invention relates to nano-Si-based composite thermal insulation paint and a preparation method thereof, belongs to the field of thermal insulation paint and aims to solve the problems of powder and slag falling, low high-temperature resistance coefficient, harm to environmental protection and high cost of existing paint. The nano-Si-based composite thermal insulation paint is prepared from thefollowing raw materials in parts by weight: 25-40 parts of waste cellucotton, 10-15 parts of a quick penetrating agent T, 20-30 parts of attapulgite hydrosol, 10-20 parts of silica hydrosol, 80-110 parts of vitrified microbeads, 5-10 parts of floating beads, 10-20 parts of expanded perlite and 380-620 parts of water. The paint comprises the waste cellucotton, a waste material is recycled, and theproblem about environmental protection is solved; ordinary insulation cotton is burnt off easily in case of fires and the protective effect on pipe equipment is lost, while the raw materials of the paint are carbonized and vitrified on surface in high-temperature flames and cannot be burnt off accordingly, and the pipe equipment is protected from losses.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a nano-silicon-based composite thermal insulation coating and a preparation method thereof, belonging to the field of thermal insulation coatings. Background technique [0002] The protective sheath of the pipeline generally has a soft protective layer and an outer sheath, and the soft protective layer and the outer sheath are bonded with paint. Now the paint generally used, the aluminum silicate wool or asbestos used in the material are all It is new, not conducive to environmental protection, and at the same time, the cost is high, and the existing coatings still have the problems of falling powder and slag after drying and molding, low high temperature resistance coefficient, and complicated materials. Contents of the invention [0003] The purpose of the present invention is to solve the problems of powder and slag falling off after drying, high thermal conduc...
