Abstract

The invention discloses a waste oil-based environment-friendly mold separating agent and a preparation method thereof. The technical scheme provided by the invention adopts key points that the waste oil-based environment-friendly mold separating agent is mainly prepared from the following raw materials by weight percent: 20 to 40 percent of waste oil, 5 to 10 percent of emulsifier, 1 to 5 percent of wetting agent, 0.1 to 2 percent of sliding component and the balance of water. The invention further discloses the preparation method of the waste oil-based environment-friendly mold separating agent and the using method thereof. The waste oil-based environment-friendly mold separating agent provided by the invention is high in temperature resistance, has a good demolding effect, has strong rust preventing performance and is high in water scouring resisting performance, and the preparation method takes waste oil as raw material, gets rid of the dependence of a traditional mold separating agent on mineral oil, not only achieves waste comprehensive utilization, but also lowers the cost, and reduces environment pollutions and harm to human bodies.

Description

technical field [0001] The invention relates to a concrete release agent and a preparation method thereof, in particular to a waste oil-based environment-friendly release agent and a preparation method thereof. The prepared release agent has good release effect, high quality cement products, low cost and Environmental protection and other advantages. Background technique [0002] In recent years, due to the improvement of living standards and the rapid development of the catering industry, waste oil produced by various fast food restaurants and restaurants has flowed into rivers, lakes and seas through sewage pipes, and even a large part of waste oil has been illegally repurchased as edible oil and continued to flow back to the dining table , causing serious food safety hazards and environmental pollution. [0003] Waste oil generally refers to all kinds of low-quality oils that exist in daily life, such as recycled cooking oil, repeatedly used frying oil, etc. If people c...
