Energy-saving and heat-insulating material and preparation method thereof

Abstract

The invention belongs to the technical field of energy-saving building materials, and provides an energy-saving and heat-insulating material and a preparation method thereof. The energy-saving and heat-insulating material is prepared from the following raw materials in parts by weight: 20 to 25 parts of clay, 16 to 29 parts of pyroclastic rock, 1 to 9 parts of expanded perlite, 4 to 5 parts of furfural resin, 1 to 3 parts of bentonite tailing powder, 5 to 11 parts of shell powder, 9 to 14 parts of sludge, 11 to 15 parts of cassava residue, 1 to 6 parts of filler, 2 to 5 parts of sawdust and 1 to 2 parts of a curing agent. The energy-saving and heat-insulating material provided by the invention has relatively good performance; the disadvantage that a thermal conductivity coefficient of an inorganic heat-insulating material is slightly large is overcome by the energy-saving and heat-insulating material, and the disadvantages that the fireproof flame-retarding performance, the anti-ageing performance and the like of an organic heat-insulating material are poor are made up; the energy-saving and heat-insulating material has actual application value. The thermal conductivity coefficient is 0.04W / (m-K) or below, and the compressive strength is 1.645MPa or above.

Description

technical field [0001] The invention belongs to the technical field of energy-saving building materials, in particular, an energy-saving thermal insulation material and a preparation method thereof. Background technique [0002] Building energy conservation is an important part of implementing the sustainable development of the national economy. In 1970, energy consumption for buildings was 10% of the gross national value. During 1988-2006, energy consumption increased at a rate of 5.6% per year. By 2006, it had grown to 25% of the gross national value. By 2020 , energy consumption for buildings may be 35% of the total GNP. Therefore, in order to achieve sustainable development of the national economy, it is imperative to implement building energy conservation. [0003] Currently used energy-saving materials are mainly divided into two categories: inorganic thermal insulation materials and organic thermal insulation materials. Benzene board, extruded polystyrene board, et...

AI Technical Summary

Problems solved by technology

This energy-saving thermal insulation material not only overcomes the deficiency of the large thermal conductivity of inorganic thermal insulation materials, but also makes up for the shortcomings of organic thermal insulation materials such as poor fire resistance, flame retardancy and aging resistance, and has practical application value.
