Thermal insulation material and preparation method thereof

Abstract

The invention discloses a thermal insulation material. The thermal insulation material is prepared from calcined kaolin, potassium permanganate, calcium stearate, polystyrene particles, a nano cementadditive, glass ceramic, hydrogen peroxide, perlite, a flame retardant and an active agent. The preparation method of the thermal insulation material comprises the following steps: S1, mixing and stirring calcined kaolin, glass ceramic, water, potassium permanganate, calcium stearate, polystyrene particles, glass ceramic, perlite and the flame retardant; S2, adding the nano cement additive; S3, adding hydrogen peroxide; S4, adding the active agent. The thermal insulation material is simple in formula, wide in raw material source and easy to obtain, the preparation method is simple and easy tooperate, and the thermal insulation material is uniform in foaming, small in product density, low in heat conductivity coefficient, capable of meeting the energy-saving standard, capable of meeting the A-level fireproof requirement and wide in application range; and the flame retardant adopted by the invention is an inorganic flame retardant, and the inorganic flame retardant has the advantages oflow heat conductivity coefficient and simple material acquisition.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to a thermal insulation material and a preparation method thereof. Background technique [0002] With the rapid development of modern industrial civilization, natural resources such as oil, coal, and natural gas have been consumed in large quantities, and energy supply has become relatively tense. The first global oil crisis in 1973 caused oil prices to soar. At this time, the world Energy issues have been widely concerned and listed as one of the four major issues that affect the survival of human beings. [0003] According to statistics, building energy consumption accounts for about 1 / 3 of global energy consumption. While building energy consumption, a large amount of pollutant CO is emitted into the atmosphere. 2 , TSP, SO 2 , NOx and other acidic gases lead to large areas of acid rain, and excessive emissions of greenhouse gases are causing global warming,...

Problems solved by technology

Although many inorganic insulation materials on the market are fireproof, they have high density, high thermal conductivity, and poor water resistance, which are far from energy-saving indicators. Although organic insulation boards have low density, good processability, and good thermal insulation effects, the products It is flammable and has low safety performance

Inorganic materials such as rock wool, mineral wool and glass wool have good thermal insulation performance and high fire resistance and can reach Class A standards, but they are expensive, high in water absorption, and inconvenient for construction
