Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with specific embodiments.

[0013] The clay non-fired light insulation brick of the present invention is composed of raw materials with the following weight ratio: MgO 2 20-28%, MgCl 2 33-41%, clay 11-35%, phosphoric acid 1-2%, water 4-12%;

[0014] The preparation method of the clay non-fired light insulation brick is characterized in that the preparation steps are as follows:

[0015] Add light-burned magnesium oxide into the magnesium chloride solution, stir well, then add clay, stir well, add protein foam and phosphoric acid, stir well, then pump it into the mold with a mud pump, let it demould after 24 hours for maintenance forming.

[0016] The filling material of the clay non-fired light insulation brick is clay with various components.

Abstract

The invention relates to a material used in the building industry, in particular to a non-burned light clay insulation brick. The insulation brick is characterized by consisting of the following raw materials based on the weight proportions: 20-28% of MgO2, 33-41% of MgCl2, 11-35% of clay, 1-2% of phosphoric acid and 4-12% of water. The preparation method of the non-burned light clay insulation brick comprises the following steps: light-burned magnesia is added to magnesium chloride; and an obtained mixture is evenly stirred, added with the clay, evenly stirred again, added with protein foam and the phosphoric acid for even stirring, pumped into a die by a slurry pump, and formed by demolding and curing after 24 hours. The preparation method is characterized in that a filling material of the non-burned light clay insulation brick is the clay with various components. As the materials required are a magnesite material and the clay, high temperature and high-pressure curing are unnecessary in production, demolding can be performed after 8 hours at normal temperature, product density is not more than 650Kg/m<3> and the heat insulation effect is obviously higher than that of the prior art. The insulation brick has the advantages of low cost, low investment and high yield, and is an environment-friendly product with low energy consumption.

Description

technical field [0001] The invention relates to a material used in the construction industry, which is a clay non-fired light heat insulating brick. Background technique [0002] At present, the production process of all fly ash aerated blocks in the construction market is to use Portland cement and fly ash mixed slurry into a high-temperature, high-pressure steam curing bin for a long time of not less than 24 hours to achieve standard strength. Disadvantages is high energy consumption. In addition, the density of the brick is not less than 900Kg / m 3 . The density is high, the product consumes high energy, and the production investment is huge. Contents of the invention [0003] The purpose of the present invention is to provide a low-cost, no need for high temperature and high pressure curing, can be demoulded at room temperature in 8 hours, and the product density is not more than 650Kg / m 3 , the thermal insulation effect is also obviously higher than that of the pri...
