Abstract

The invention relates to aerated brick release oil and a preparation method thereof, and belongs to the technical field of chemical raw materials and preparation methods thereof. A demoulding oil for aerated bricks, made of the following raw materials in parts by weight: 20-30 parts of pine oil, 5-10 parts of glycerin, 10-15 parts of sodium petroleum sulfonate, and 2-6 parts of sodium nitrate , 2-5 parts of stearic acid, 5-9 parts of sodium hydroxide, 10-15 parts of triethanolamine, 20-30 parts of carboxymethyl cellulose, 5-10 parts of emulsifier, 5-10 parts of saponin, 5 parts of ethanol -10 parts, 10-20 parts of bentonite, 5-9 parts of waste engine oil, 3-8 parts of β-hydroxymalonic acid, 50-100 parts of water. The release oil for aerated bricks of the present invention is based on pine oil as the main raw material, and added glycerin, saponin, etc., and also fully utilizes industrial waste engine oil, so that the final product release oil can ensure the quality of aerated bricks. It is easier to separate from the mold, and ensure that the surface of the aerated brick is smooth and tight after demoulding.

Description

technical field [0001] The invention relates to aerated brick release oil and a preparation method thereof, and belongs to the technical field of chemical raw materials and preparation methods thereof. Background technique [0002] Aerated brick is a kind of aerated concrete block produced by high temperature autoclaved equipment. It has the characteristics of light weight, good thermal insulation performance, strong shock resistance, good processing performance, high temperature resistance, and good sound insulation performance. Because of its hollow characteristics, it is flexible, and the main body of the building is supported by the reinforced concrete structure. When an earthquake occurs, the hollow aerated brick can leave enough expansion space for the reinforced concrete structure, so the aerated brick is used Widely used in modern architecture. However, the demoulding process in the production process of aerated bricks has become a key step in the production of qual...
