Efficient energy-saving environment-friendly heat preservation material and preparing method thereof

Abstract

The invention relates to an efficient energy-saving environment-friendly heat preservation material and a preparing method thereof. The material is prepared from wheat straw, clay, vesuvianite slag, coal ash, quick lime, binding agents, a softening agent and a catalyst. The binding agents comprise a binding agent A and a binding agent B. Water glass or cement or gypsum is adopted as the binding agent A. Corn starch paste or sticky rice paste or konjak powder paste with the solid content being 2% is adopted as the binding agent B. All the components are subjected to the steps of smashing, mixing, softening, thickening, catalytic fermenting, forming and the like according to a certain weight part. Compared with the prior art, the raw materials used in the method are environmentally friendly or reproducible, conform to the environmental protection idea, and are free of firing, light and low in price.

Description

technical field [0001] The invention relates to a preparation method of a thermal insulation material, in particular to a high-efficiency, energy-saving and environment-friendly thermal insulation material and a preparation method thereof. Background technique [0002] At present, the insulation materials commonly used at home and abroad are divided into two types: organic matter and inorganic matter. Organic building insulation materials include polystyrene foam (EPS, XPS), polyurethane rigid foam (PU), etc., which have the advantages of light weight, heat preservation, heat insulation, and waterproof. However, these organic foam materials are easy to age and cannot last the same life as the building. During the service life of the building, the insulation layer needs to be replaced many times. In addition, EPS, XPS, PU, ​​etc. are high-molecular organic materials, which are flammable and not resistant to high temperatures. , The burning speed is fast, and a large amount o...

Problems solved by technology

The invention controls the amount of manganese dioxide catalyst to control the foaming process to ensure the strength of the inorganic foam thermal insulation material while reducing its thermal conductivity and enhancing the thermal insulation effect, and adds perlite as an anti-slump agent to reduce the reject rate, and at the same time adds triethanolamine Improve the performance of inorganic foam insulation materials and prepare new inorganic foam building insulation materials. The insulation materials produced by this invention have the characteristics of no heat energy, but the polypropylene fibers and triethanolamine used in the materials are still non-renewable organic materials. It is not a pure inorganic environmental protection material, and inorganic materials such as sulfoaluminum silicate cement and calcium stearate have a large proportion, so the finished product has the defects of large specificity and high thermal conductivity
