Embodiment 1

[0042] The manufacturing method of the thermal insulation wall material of the present invention is a processing and molding process in which waste soil, diatomite and admixture are mixed according to a certain proportion and then processed through a technological process.

[0043] 1. The contents of waste soil, diatomite and admixture are as follows (percentage by weight): waste soil is 60%, diatomite is 30%, and admixture is 10%; coal or fly ash in the admixture The weight ratio between sawdust powder, chaff, wheat straw or straw and one or more plant fibers is 1:3.

[0044] ②. The process flow includes:

[0045] A. Raw material preparation: Prepare the above-mentioned required raw materials. Transport waste soil - silt, river mud or mountain mud to the site for stacking, purchase diatomaceous earth and transport it to the site for storage; purchase coal or fly ash and stack it on site; prepare sawdust, chaff, wheat straw or straw etc., store separately.

Abstract

The present invention is making process and product of heat insulating wall material. Waste mud, diatomite and admixture in certain weight proportion are mixed and produced into the heat insulating wall material through certain technological process. The product is cuboid with crossed rectangular holes capable of lengthening heat flow path, and has porosity of 30-50 %, heat conducting coefficient smaller than 1.3 KW / sq m.K, 25 % ; lower than that of traditional clay brick and high durability. The product may be used widely in heat insulation one outer building wall.

Description

technical field [0001] The invention relates to a manufacturing process of wall materials in the field of construction, and relates to a method for manufacturing heat-insulating wall materials and the produced heat-insulating wall materials. The products are mainly used in civil or industrial buildings for heat preservation and energy saving. Background technique [0002] Today's resource issues are primarily energy issues, of which building energy consumption accounts for 27.8% of total energy consumption. In building energy consumption (including construction energy consumption and use energy consumption), the use energy consumption accounts for more than 80% of building energy consumption. The thermal insulation performance of the building envelope determines whether the building is energy efficient or not, and the outer wall accounts for the largest proportion of the building envelope, and the heat loss caused by the heat transfer of the wall accounts for 50% of the heat...
