Problems solved by technology

The traditional demoulding material is engine oil or waste engine oil plus diesel oil. In the long-term construction of water conservancy and hydropower, highways, railways and other projects, it has been found that using waste engine oil to paint the formwork will pollute the concrete surface and cause varying degrees of damage to the environment. Pollution; the use of finished engine oil needs to be diluted with diesel oil, so it is difficult to control the proportion and brushing effect on site, and the use cost is high, and there are also different degrees of pollution; the use of salad oil is better for brushing, but the cost is too high. Food grade oil is not easy to control
All kinds of water-soluble release agents and oil-soluble release agents currently on the market are not ideal in actual use

Abstract

The invention discloses an environment-friendly oily emulsion release agent. The environment-friendly oily emulsion release agent is prepared from the following raw materials in percentage by weight: 50-60% of oily substance, 0.2-0.6% of polyoxyethylene ether, 0.05-0.1% of triethanolamine, 0.2-0.5% of a water-based silane coupling agent, and the balance of deionized water, wherein the oily substance is mineral oil, or used oil and mineral oil, or gutter oil and mineral oil. The invention further discloses a preparation method of the release agent. The release agent has the oil-water compatible characteristic, solves the problems of incompatibility of oil and water and layering, can be diluted with water for long-time preservation without layering, avoids the pollution to concrete surface by using the used oil, prevents the corrosion of the water-soluble release agent to a steel template, and avoids diluting engine oil by using diesel in the past. The environment-friendly oily emulsion release agent is milk-white liquid capable of being sprayed and coated, is conveniently used, suitable for various concrete templates, and colorless and transparent when being coated on the templates, and has good adhesiveness.

Description

technical field [0001] The invention belongs to the technical field of concrete release agents, in particular to an environment-friendly oily emulsion 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 mold release material is to use oil or waste oil and diesel oil. In the long-term construction of water conservancy, hydropower, highway, railway and other projects, it is found that the use of waste oil to paint the formwork will pollute the concrete surface and cause different degrees of environmental damage. Pollution; the use of finished engine oil needs to be diluted with diesel oil, so it is difficult to control the...
