Embodiment

[0024] A new type of building thermal insulation material composition produced by utilizing drift sand, its raw material composition and weight ratio are:

[0025] Aeolian sand 85%, soda ash 2%, talc 2%, soda ash 3%

[0026] Limestone 1%, silicon carbide 5%, sodium fluorosilicate 2%.

[0027] A preparation method for producing a new type of building thermal insulation material composition using aeolian sand, the preparation method and steps are:

[0028] (1) Screening ingredients: After the aeolian sand is screened, it is formulated according to the ratio of aeolian sand 85%, soda ash 2%, talc 2%, soda ash 3%, limestone 1%, silicon carbide 5%, and sodium fluorosilicate 2%. It is required to add high-temperature solvent raw materials borax, talc, soda ash, sodium fluorosilicate and additives limestone and silicon carbide to the aeolian sand and weigh and mix together;

[0029] (2) Wet fine grinding: the raw materials after wet fine grinding can be fully mixed, and the particl...

Abstract

The invention relates to a novel building thermal insulation material composition produced from drift-sand and a preparation method thereof and belongs to the technical field of manufacturing of ceramic products. The main technical characteristic of the invention is as follows: the raw material composition of the novel building thermal insulation material composition consists of 60-92% of drift-sand, 0-12% of borax, 1-4% of talc, 3-8% of soda, 2-7% of sodium fluosilicate, 2-12% of silicon carbide and 2-15% of limestone. A standard building thermal insulation material is processed through raw material screening, blending, fine grinding, flour milling, forming, firing and cutting. The novel building thermal insulation material composition disclosed by the invention has less raw material components, the preparation method is simple, the drift-sand is used as the main raw material, and the cost is low, so that the preparation method is a new technology for changing harmful substances into treasures, and the novel building thermal insulation material composition has the advantages of good thermal insulation properties, incombustibility, high strength, low water-absorption rate, corrosion resistance, convenience in mounting and the like. Meanwhile, one of better ways for industrial desertification control is provided, the erosion of deserts to the land can be reduced, farmland and green areas are expanded, and pollutions of the drift-sand to the environment can be greatly improved.

Description

1. Technical field [0001] The invention relates to a thermal insulation material, in particular to a composition and a preparation method for producing a new type of building thermal insulation material by using aeolian sand, which belongs to the technical field of manufacturing chemical products and new type of building thermal insulation material, including a preparation method. 2. Background technology [0002] At present, the insulation materials used in building exterior walls mainly include polystyrene board and rock wool board. Polystyrene board is an organic thermal insulation material. It is made of polystyrene raw materials through pre-expansion, curing, molding, drying and cutting processes. Due to its low thermal conductivity, it has good thermal insulation performance. Polystyrene boards are divided into two types: combustible and flame-retardant. Currently, the combustible polystyrene boards used in the market have caused many safety accidents, resulting in hug...
