Problems solved by technology

[0006] First, the pouring stability of sand air-entrained concrete products will deteriorate with the decrease of product dry density. Therefore, at present, almost no enterprises can produce dry density less than 255Kg / m 3 sand aerated concrete block
[0007] Second, the sand aerated concrete block (plate) is an inorganic non-metallic material, and its products are brittle, which limits its use effect and is not convenient for product transportation

Abstract

The invention discloses a fireproof insulation board of aerated concrete of B02-level light sand. The constituents and weight percentages of the fireproof insulation board are as follow: 45-55% of quartz sand, 12-16% of lime, 24-37% of cement, 5% of gypsum, 0.25-0.35% of aluminite powder and 0.2-0.6% of composite admixture, wherein the composite admixture is admixture with composite stabilizing, toughening and waterproof functions, and the constituents and weight percentages are as follow: 25-30% of sodium abietate, 22-26% of chlorinated paraffin, 24-28% of petroleum ether and 20-25% of organo-siloxane. The fireproof insulation board has the advantages that the fireproof insulation board compensates the disadvantages and defects of the prior art, overcomes the production difficulties, and improves the casting stability when reducing dry density of the aerated concrete product of the sand, so as to conveniently transport and construct the product, and meet huge demands of the construction market and energy conservation and environmental protection requirements of people on building materials in cities.

Description

technical field [0001] The present invention relates to a light inorganic non-metallic fireproof and thermal insulation material. More specifically, the present invention relates to a B02 grade sand additive with a dry density lower than the lowest grade in the national standard GB 11968-2006 and a compressive strength greater than or equal to 0.5MPa. Air concrete fire insulation board. Background technique [0002] At present, most of the external insulation materials in the domestic construction market are organic polymer materials, and these organic polymer materials are flammable and combustible, and will release toxic gases when they encounter open flames. Environmental protection, non-toxic, low VOC requirements. [0003] Based on this, people in the industry have carried out relevant research, hoping to develop a new type of inorganic non-metallic environmental protection material to replace the aforementioned organic polymer products, in order to overcome many short...
