Abstract

The invention relates to a refractory thermal insulation material and a preparing method thereof. The refractory thermal insulation material is prepared from, by weight, 10-16 parts of fruit shell powder, 10-15 parts of feldspar, 50-60 parts of shale, 10-13 parts of sandstone, 1-3 parts of limestone, 5-8 parts of magnesite, 5-7 parts of modified nano silica and a proper amount of water through high-temperature foaming after water is added for mixing. The surface of the refractory thermal insulation material is coated with a flame retardant. The prepared refractory thermal insulation material has good mechanical performance and refractory performance, is low in manufacturing cost and low in environmental pollution and belongs to environment-friendly materials.

Description

technical field [0001] The invention relates to a fire-proof and heat-preserving material and a preparation method thereof. Background technique [0002] For building insulation materials, in the 1970s, some developed countries such as Germany, the United States, France, etc. paid attention to and started research and promulgated a series of related policies for this purpose. Effective regulation of construction by the state. So good results were obtained. The United States has developed from 1987 to the present, and the thermal insulation materials used in construction account for as high as 81% of all thermal insulation materials, and the thermal insulation materials are mainly added to light steel structures. Energy consumption funds for buildings have been greatly reduced, and it is expected to reduce energy consumption tariffs by another US$ 43 billion in 3 years. At present, there are mainly two types of thermal insulation materials used in external wall thermal ins...
