Problems solved by technology

[0003] Because the mold release agent using waste engine oil has a strong smell and contains a large amount of volatile solvents, it will damage the respiratory health of on-site workers, and the large amount of waste engine oil will also cause soil and water pollution. In addition, waste engine oil and diesel oil belong to Flammable material, risky for storage

Abstract

The invention discloses a novel aerated concrete environment-friendly demolding agent as well as a preparation method and a use method thereof, and relates to the technical field of demolding agents. The novel aerated concrete environment-friendly demolding agent consists of the following substances in parts by weight: 10-50 parts of waste engine oil, 1-10 parts of a diluent, 0.1-5 parts of an emulsification complexing agent, 0.1-1 part of a bactericide, 0.1-0.5 part of a defoaming agent and 20-70 parts of water. By adopting the novel aerated concrete environment-friendly demolding agent, environment protection can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a novel aerated concrete environment-friendly release agent and methods for its preparation and use. Background technique [0002] Existing demolding of aerated concrete mainly uses waste engine oil and diesel oil mixed and then brushed or sprayed onto the surface of the formwork, and an isolation film is formed after drying, thereby effectively demoulding, and the demoulding oil needs to be painted or sprayed again every time demoulding. [0003] Because the mold release agent using waste engine oil has a strong smell and contains a large amount of volatile solvents, it will damage the respiratory health of on-site workers, and the large amount of waste engine oil will also cause soil and water pollution. In addition, waste engine oil and diesel oil belong to Flammable material, hazardous for storage. Contents of the invention [0004] Aiming at the defects existing in...
