Preparation method of thermal insulation material

Abstract

The invention relates to a preparation method of a thermal insulation material. The material comprises the following raw materials: 30-50 parts of basalt powder, 10-15 parts of perlite powder, 5-10 parts of rutile titanium dioxide, 5-8 parts of ceramic powder, 1-5 parts of calcium oxide, 1-5 parts of sodium nitrate, and 1-3 parts of a smell removing agent. The basalt powder, the perlite powder, the rutile titanium dioxide, the ceramic powder, calcium oxide, and sodium nitrate are mixed and injected into a reaction vessel, the reaction temperature is 85-105 DEG C, after sodium nitrate is fully dissolved, the smell removing agent is added with stirring, the reaction is stopped, and cooling is carried out. The method has the advantages of simple process and short production period; warming plates prepared by the material has the advantages of light mass, good thermal insulation effects without toxicity and stimulating smell, and wide application range.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of a thermal insulation material. Background technique [0002] Thermal insulation materials are widely used in the construction field. At present, most of the existing thermal insulation materials are made of polystyrene. Although the waterproof and anti-leakage effect is good, the insulation board made is relatively bulky and has a strong pungent taste, which affects the use in construction. The preparation process of the material is relatively complicated, the production cycle is long, and the production cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing a thermal insulation material with simple process, short production cycle, light weight of the prepared thermal insulation board, good thermal insulation effect, non-toxic and non-irritating smell. [0004] The technical scheme ad...
