Green energy-saving building material and preparation method thereof

Abstract

The invention discloses a green energy-saving building material and a preparation method thereof. The green energy-saving building material is prepared from the following raw materials in parts by weight: 8 to 22 parts of sepiolite powder, 6 to 17 parts of bentonite, 5 to 15 parts of ethylene propylene diene monomer, 11 to 18 parts of fly ash, 9 to 20 parts of tetracalcium aluminoferrite, 6 to 14parts of calcium hypophosphite, 5 to 11 parts of zinc borate, 3 to 8 parts of nano silicon dioxide and 5 to 9 parts of aluminum silicate wool. The building material composed of sepiolite powder, bentonite, ethylene propylene diene monomer, fly ash, tetracalcium aluminoferrite, calcium hypophosphite, zinc borate, nano-silica and aluminum silicate wool has the advantages of high strength and low energy consumption. The energy-saving building material is applied to buildings, the energy consumption of the buildings can be effectively reduced on the premise that the strength of the buildings is guaranteed, and the problems in the prior art that a conventional building material is common in energy-saving effect, and the energy consumption of the buildings cannot be effectively reduced are solved. The bricks of the building material can be prepared through the processes of mixing, pressing, slitting and forming.

Description

technical field [0001] The invention belongs to the field of building technology, and relates to a building material and a preparation method thereof, in particular to a green energy-saving building material and a preparation method thereof. Background technique [0002] The level of building energy consumption depends on the thermal insulation performance of the building envelope and the airtightness of the building. [0003] Reference document CN105819778A discloses a method for preparing a lightweight, heat-insulating, and environment-friendly composite wall building material. The building coating components include cellulose, carbon fiber particles, rubber particles, plant particles, low-density polyethylene resin, silicone modified Permanent epoxy resin, calcium carbonate, magnesium oxide, magnesium silicate, calcium magnesium carbonate, calcium borate, nano silicon oxide, lightweight ceramics, EVA redispersible rubber powder, etc. The building wall paint provided by t...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the prior art, the energy-saving effect of conventional building materials is relatively general and cannot effectively reduce the energy consumption of buildings; the stirring shaft is equipped with stirring paddles for stirring, and the stirring method makes the bottom of the tank The stirring speed of the material is slow, resulting in poor fluidity, so that the bottom material cannot be fully stirred; at the same time, during the mixing process, the material is also easy to stick to the inner wall of the mixing tank, which affects the yield of building materials; There are high resource and fuel consumption, complicated process, easy to cause pollution to the environment, the texture of the building materials is loose, the strength is not enough, and some raw materials are small in stock, limited by geographical conditions, it is not suitable for large-scale production problems, and propose a green energy-saving building material and its preparation method
