Problems solved by technology

[0002] Concrete release agent is also called concrete release agent or release lubricant; it is a substance that is applied to the inner wall of the formwork to lubricate and isolate, so that the concrete can be smoothly separated from the formwork when the formwork is removed, and the shape of the concrete is kept intact. The traditional release agent The mold material is made of engine oil or waste engine oil plus diesel oil. In the long-term construct...

Abstract

The invention discloses a safe and environment-friendly concrete mold release agent and a preparation method thereof. The concrete mold release agent comprises the following raw materials in parts by weight: 48-55 parts of modified waste oil, 3-4 parts of talc powder, 5-6 parts of sodium carboxymethyl cellulose, 0.6-0.8 part of alkylphenol polyoxyethylene ether, 4-5 parts of gypsum powder, 2-3 parts of urea, 0.5-0.6 part of methenamine, 2-4 parts of bamboo carbon powder, 0.1-0.3 part of hydroxyethyl acrylate, 0.3-0.8 part of methyl methacrylate, 1.0-1.2 parts of sodium petroleum sulfonate and 350-400 parts of deionized water. The mold release agent disclosed by the invention has the advantages of easiness in spraying, good adhesion, smoothness in exhausting and the like and is suitable for pouring concrete, the phenomena of pores, cracks and the like of concrete can be effectively decreased, the purpose of treating wastes with wastes is achieved, the full recycling of resources is realized and the concrete mold release agent has larger application values.

Description

technical field [0001] The invention provides a concrete release agent, in particular to a safe and environment-friendly concrete release agent and a preparation method thereof. Background technique [0002] Concrete release agent is also called concrete release agent or release lubricant; it is a substance that is applied to the inner wall of the formwork to lubricate and isolate, so that the concrete can be smoothly separated from the formwork when the formwork is removed, and the shape of the concrete is kept intact. The traditional release agent The mold material is made of engine oil or waste engine oil plus diesel oil. In the long-term construction of water conservancy, hydropower, highways, railways and other projects, it is found that the use of waste engine oil to paint the formwork will pollute the concrete surface and cause different degrees of pollution to the environment; but The existing release agent has poor demoulding effect, is difficult to remove on the fo...
