A method for preparing ultra-light pipe insulation material

Abstract

The invention discloses a method for preparing an ultra-light pipeline insulation material. The raw material components are as follows in weight percentage: 17.5-22.5% of quartz powder; 18.2-20.1% of quicklime; 41.3-43.1% of water; 8.1-9.2% of red mud; 0.1-0.12% of agent; 6.1-7.2% of bentonite; 0.2-0.3% of reinforcing fiber; 0.1-0.15% of fiber dispersant; the material preparation steps include: (a) raw material selection; ; (d) compression molding; (e) steam curing; (f) drying; (g) product testing and insulation pipeline production; (h) finished product packaging. The present invention adds red mud to the composition of raw materials, reducing the cost of preparing pipeline insulation materials; adding the filtered red mud liquid component into the reaction kettle with agitation, and the sides, corners and edges of the pressed and formed products are not damaged, The appearance quality of the product is improved, and the prepared thermal insulation material has the advantages of low thermal conductivity, high strength, low density, easy processing and no corrosion of pipelines.

Description

technical field [0001] The invention relates to a thermal insulation material and a preparation method, in particular to a method for preparing an ultralight pipeline thermal insulation material. Background technique [0002] Since the energy crisis, energy saving has been paid more and more attention by various countries. According to reports, so far, the application of energy-saving technology has reduced the total energy consumption in the world by 20-30%. Among various energy-saving technologies, building thermal insulation technology develops very rapidly due to its remarkable energy-saving benefits, less investment, and faster recovery. [0003] Building thermal insulation is an important aspect of saving energy, improving the living environment and using functions. Building energy consumption generally accounts for 30-40% of the total energy consumption of human beings, most of which are heating and air conditioning energy consumption, so building energy conservatio...

Problems solved by technology

At present, the calcareous raw materials required for the production of this material at home and abroad mainly use quicklime, slaked lime, etc., so a large amount of limestone needs to be mined, thereby destroying vegetation and causing damage to the ecological environment; after the pipe insulation material is pressed, the demoulding effect is general. Products often have damage at the corners, which reduces the appearance quality of the product; and the pipe connection is not dense, the insulation effect is not optimal, so that after the installation of insulation materials, energy is greatly wasted
