A kind of water-based thermal insulation and fireproof material and preparation method thereof

Abstract

The invention discloses an aqueous heat-insulation heat-preservation fireproof material. The aqueous heat-insulation heat-preservation fireproof material is prepared from the following components in percentage by weight: 8 to 20 percent of nano silicon oxide composite material obtained by compounding structurally-controlled nano silicon oxide powder and a nano silicon oxide cake material with an ultrahigh specific surface area according to a proportion of 0.5:(1-5):1, 3 to 15 percent of glass micro-beads, 4 to 10 percent of nano titanium oxide, 1 to 8 percent of potassium titanate, 1 to 8 percent of titanium pyrophosphate, 1 to 3 percent of aluminum hydroxide, 1 to 3 percent of zinc borate, 1 to 3 percent of barium borate, 1 to 3 percent of calcium sodium metasilicate, 1 to 10 percent of aluminum silicate, 20 to 28 percent of acrylic hybrid emulsion, 1.5 to 3 percent of other assistants, and the balance of water. According to the aqueous heat-insulation heat-preservation fireproof material disclosed by the invention, the nano silicon oxide composite material obtained by compounding structurally-controlled nano silicon oxide powder and the nano silicon oxide cake material with the ultrahigh specific surface area as a core material, and by the components and corresponding optimized improvement of the proportions, the product has a good heat-flow stagnation function; and the heat conduction coefficient of the product is not more than 0.03W / (m.K), and the waterproof performance reaches A level.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a water-based thermal insulation and fireproof material and a preparation method thereof. Background technique [0002] With the development of society and the requirements of low-carbon environmental protection, energy saving and consumption reduction has become a major issue in energy application and scientific research. Thermal insulation materials are a new type of functional materials developed under this social background. Building energy consumption is one of the important components of the total energy consumption of human beings. At the same time, building energy consumption is also a major source of pollution. At present, China's building energy consumption accounts for about 30% of the total energy consumption of the whole society. According to the experience of developed countries, this proportion will gradually increase to about 40%. ...

Problems solved by technology

For example, the patent CN104231917A discloses a nano high-temperature heat-resistant and heat-insulating coating prepared by utilizing silica airgel, inorganic nano-titanium oxide, nano-alumina, glass hollow microspheres, flame retardants and functional additives. The coating can effectively Reduce the heat transfer efficiency, but because of the particularity of the performance of silicon oxide materials, not only the price of raw materials is expensive, but also its performance is unstable and the heat preservation effect is not ideal
