Problems solved by technology

At present, the traditional thermal insulation technology is mainly rock wool technology. The main disadvantage of rock wool technology is that it is highly corrosive, and it is easy to corrode the steel structure of containers, equipment or pipelines. Rock wool cannot see water, otherwise it will greatly affect the thermal insulation effect; traditional Insulation technology also includes composite silicate technology. The main disadvantage of silicate insulation materials is that the drying cycle is long, the construction is greatly affected by seasons and climates, and the bonding strength to the substrate is low. Improper construction can easily cause large-scale hollowing.
The above-mentioned traditional thermal insulation technologies cannot achieve the ideal thermal insulation effect.

Abstract

The invention relates to a steel structure surface insulation anticorrosion paint. The steel structure surface insulation anticorrosion paint comprises the following components by weight percentage: a main material is composed of 5-9% of special ceramics particles, 5-7% of rutile titanium dioxide R258, 10-12% of F-197# bisphenol A anticorrosion resin, 12-15% of vinyl ester resin, 10-14% of organosilicon-acrylic resin ACR-901, 6-8% of nano rare earth and 2-3% of special fire retardant; and an auxiliary material composed of 6-9% of CPA-100P aerogel particles, 2-4% of dispersant P-19, 2-4% of wetting dispersant W-18, 1-2% of stabilizing agent Acrysol<TM> RM-825, 5-10% of deionized water; and 20% of additive. The insulation anticorrosion paint has the advantages of low conductivity, good insulation effect, anticorrosion and moisture resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation and anticorrosion coating for the surface of steel structures. Background technique [0002] The steel structure surface of industrial containers and equipment is suitable for the outer surface of petroleum, petrochemical, electric power, railway, food, electronics and other related equipment. Insulation treatment is very critical when the temperature is high in summer. At present, the traditional thermal insulation technology is mainly rock wool technology. The main disadvantage of rock wool technology is that it is highly corrosive, and it is easy to corrode the steel structure of containers, equipment or pipelines. Rock wool cannot see water, otherwise it will greatly affect the thermal insulation effect; traditional Insulation technology also includes composite silicate technology. The main disadvantage of silicate insulation materials is that the drying cycle is ...
