Method for preparing fibre composite heat insulating wall material

Abstract

The invention provides the production process of a composite thermal-insulating fiber wall material, which comprises the following steps: (1) mixing at least one of inorganic fiber and wood fiber withwater at a rate (by weight part) of fiber to water equal to (10 to 50): 1,000, stirring, and expanding to obtain a base material; (2) adding an aggregate into the base material at a rate (by weight part) of water to aggregate equal to 1,000:(80 to 120), and mixing uniformly to obtain a material; and (3) adding a gel agent into the material at a rate (by weight part) of material to gel agent equalto 1:(0.1 to 0.3), mixing uniformly to obtain the wall material. The material can be used for manufacturing wall blocks of different sizes by direct casting, mold filling, or manufacture. The processhas short flow, simple operation, low cost, no discharge of harmful substances, environmental protection, and reduced energy consumption. The wall material has a thermal conductivity of 0.056 W / m.k,and the blocks manufactured from the wall material has a compressive strength reaching the national standard. The wall material is widely used for inner or outer wall material.

Description

technical field [0001] The invention relates to a production process of a wall material, in particular to a production process of a fiber composite heat-insulating wall material. Background technique [0002] The energy problem is one of the important issues of global concern. Countries all over the world are trying to reduce energy consumption and save energy through various means. Among them, building energy consumption accounts for about 1 / 4 of the total energy consumption, and building energy conservation has a direct relationship with building materials. To reduce building energy consumption, we must start with building materials, especially the thermal insulation of walls plays a key role in reducing building energy consumption. Therefore, it is of great significance to develop and study wall materials for thermal insulation. At present, the form adopted is to add a layer of heat insulation layer on the wall surface. Although it can reduce building energy consumption,...
