Embodiment 1

[0027] The technical solution adopted by the present invention is a method for preparing foam insulation building materials using soot carbon powder as a foaming agent. The steps of the method include:

[0028] (1) Mixture treatment: Weigh the soot toner foaming agent, raw materials, fluxing agent, and foam stabilizer according to the mass percentage of the mixture, add them into a ball mill tank to obtain the mixture, and then carry out dry pressing molding of the mixture. The formed blank is put into the mould;

[0029] In this step, the mass percentages of each component in the mixture are: 3% ball-milled soot carbon powder foaming agent, 85% ball-milled raw materials, 9% flux, and 3% foam stabilizer. The raw material is waste glass. The flux is borax; the foam stabilizer is sodium phosphate. The particle size of the mixture obtained after ball milling in the ball mill tank is less than 200 mesh. Ensure the smaller particle size, so as to ensure the uniformity and produc...

Embodiment 2

[0038] On the basis of Example 1, this example is a method for preparing a foam insulation building material using soot carbon powder as a foaming agent. The steps of the method include:

[0039] (1) Mixture treatment: Weigh the soot toner foaming agent, raw materials, fluxing agent, and foam stabilizer according to the mass percentage of the mixture, add them into a ball mill tank to obtain the mixture, and then carry out dry pressing molding of the mixture. The formed blank is put into the mould;

[0040] In this step, the mass percentage of each component in the mixture is: 2% of ball-milled soot carbon powder foaming agent, 80% of ball-milled raw material, 16% of flux, and 2% of foam stabilizer. The raw material is fly ash. The flux is borax; the foam stabilizer is sodium phosphate. The particle size of the mixture obtained after ball milling in the ball milling tank is less than 200 mesh.

Embodiment 3

[0048] On the basis of Embodiment 1, this embodiment is a method for preparing foam thermal insulation building materials by using soot carbon powder as a foaming agent, and the steps of the method include:

[0049] (1) Mixture treatment: Weigh the soot and carbon powder foaming agent, raw materials, fluxing agent, and foam stabilizer according to the mass percentage of the mixture, add it into a ball mill tank and ball-mill to obtain a mixture, and then dry-press the mixture to form the mixture. The formed blank is put into the mold;

[0050] In this step, the mass percentages of each component in the mixture are: 4% ball-milled soot carbon powder foaming agent, 75% ball-milled raw material, 16% fluxing agent, and 5% foam stabilizer. The raw material is fly ash. The flux is borax; the foam stabilizer is sodium phosphate. The particle size of the mixture obtained after ball milling in the ball milling tank is less than 200 mesh.

[0051] (2) Preheating stage treatment: The ...

Abstract

The invention discloses a method for preparing a foam thermal insulation building material by using soot carbon powder as a foaming agent. The steps of the method include: processing a mixture; processing in a preheating stage; processing in a foaming stage; processing in a foam stabilizing stage; and cooling processing . The preparation method uses soot carbon powder as a foaming agent, can effectively and rationally utilize natural resources, effectively reduce the production cost of foam insulation building materials, reduce environmental pollution, save natural resources, effectively utilize waste materials, and reduce environmental pollution of materials and building material cost; the foam insulation building material prepared by the inventive method has a density of 0.27-0.62g / cm3, a strength of 2.32-8.96MPa, a porosity of 76-88%, and good building insulation performance, which is better than existing foam insulation Building materials have higher performance and lower production costs, and have greater promotion and application value.

Description

technical field [0001] The invention relates to a method for manufacturing a foam thermal insulation building material, in particular to a method for preparing a foam thermal insulation building material by using soot carbon powder as a foaming agent. Background technique [0002] my country's high-pollution and high-emission industries mainly include non-metallic mineral product processing industry and power industry. With the acceleration of China's urbanization process and rapid economic development, the market size of my country's steel structure will grow steadily, and the metallurgical industry, metal abrasives and shot (spray) pills will also develop further. In the process of using high-frequency electric furnaces and medium-frequency induction furnaces to recycle scrap metal, high-molecular organic matter such as impurities, coatings, paints, and electroplating protective layers attached to scrap metal materials are carbonized at high temperatures into fine industri...
