Abstract

The invention discloses an environment-friendly release agent for autoclaved aerated concrete blocks. The environment-friendly release agent is prepared from the following raw materials in parts by weight: vegetable oil, a POSS-phosphorylated vegetable oil polymer, polyethylene glycol, nano calcium carbonate, ammonium polycarboxylate, a compound emulsifier, C12 alcohol ester, emulsified silicone oil, xanthan gum and water. The invention also discloses a preparation method of the environment-friendly release agent for autoclaved aerated concrete blocks, which comprises the following steps: dispersing the POSS-phosphorylated vegetable oil polymer into the vegetable oil containing polyethylene glycol to obtain a dispersion liquid; dissolving a compound emulsifier, emulsified silicone oil and xanthan gum in hot water to obtain emulsified water; and adding nano calcium carbonate, ammonium polycarboxylate and emulsified water into the dispersion liquid, adding the C12 alcohol ester and adding water for dilution, and uniformly stirring all the components to obtain the modified vegetable oil environment-friendly release agent. The release agent disclosed by the invention has the advantages of high film forming speed, small adhesion amount, low cost, no toxicity, no pollution and good release effect.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to an environmentally friendly release agent for autoclaved aerated concrete blocks and a preparation method thereof. Background technique [0002] The autoclaved aerated concrete block is made of fly ash, lime, cement, gypsum, slag, etc. A porous concrete product made by steam curing and other processes. The weight per unit volume of autoclaved aerated concrete blocks is one-third that of clay bricks, the thermal insulation performance is 3 to 4 times that of clay bricks, the sound insulation performance is twice that of clay bricks, and the impermeability is more than double that of clay bricks. , the fire resistance is 6 to 8 times that of reinforced concrete, and the masonry strength of the block is about 80% of the strength of the block itself (30% for the red brick). [0003] In the construction of autoclaved aerated concrete blocks, the sur...
