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, flux, and foam stabilizer according to the mass percentage of the mixture, add them to 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 product performan...

Abstract

The invention discloses a method for preparing a foam thermal-insulation construction material by using smoke dust carbon powder as a foaming agent. The method comprises the following steps: mixture treatment, preheating-stage treatment, foaming-stage treatment, foam-stabilizing-stage treatment and cooling treatment. By using the smoke dust carbon powder as the foaming agent, the preparation method effectively and reasonably utilizes the natural resources, thereby effectively lowering the production cost of the foam thermal-insulation construction material, reducing the environmental pollution and saving the natural resources; and the preparation method effectively utilizes the waste material, thereby lowering the environmental pollution and cost of the construction material. The density of the foam thermal-insulation construction material is 0.27-0.62 g/cm<3>, the strength is up to 2.32-8.96 MPa, and the porosity is 76-88%. The foam thermal-insulation construction material has favorable architectural thermal-insulation property, has the advantages of higher performance and lower production cost than the existing foam thermal-insulation construction material, and has high value for popularization and application.

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...
