A kind of waste oil diluent and its application in preparing mold release agent

Abstract

The invention discloses a waste engine oil diluent and its application in preparing a release agent, belonging to the technical field of building release agents. The key points of the technical solution of the present invention are: a waste engine oil diluent, which is prepared from the following raw materials in parts by weight: 15-35 parts of petroleum acid, 20-40 parts of alcohols, 10-30 parts of ethers and 10-30 parts of nonionic surfactant. The invention also discloses the application of the waste engine oil diluent in preparing the release agent. The waste engine oil diluent described in the present invention has good stability, low toxicity, and less harm to the human body. In particular, water is used as the raw material for dilution, which is safer and more environmentally friendly than waste gasoline or waste diesel oil, and its components are cheap and easy to use. Yes, it is conducive to further popularization and application.

Description

technical field [0001] The invention belongs to the technical field of building release agents, and in particular relates to a waste engine oil diluent and its application in preparing release agents. Background technique [0002] The recycling of waste engine oil in my country began in the 1930s, entered its heyday in the 1970s, and the engine oil sales market opened after the 1980s. Because the recovery of waste engine oil in the remanufacturing plants of oil companies in various places was less than the expected amount, they turned to engine oil blending. After the 1990s, most of the professional remanufacturing plants were in the 100-ton class, and there were very few large-tonnage manufacturers. In general, my country's waste engine oil regeneration technology is relatively backward, with small scale and simple process. With the progress of society, the application of various industrial machinery, the production and consumption of engine oil are increasing, which will ...

Problems solved by technology

However, the viscosity of waste engine oil is very high, and it cannot be directly applied to the release agent, and it must be diluted before use.

At present, most of the existing dilution methods use waste gasoline or waste diesel oil as the diluent, which is costly, and gasoline is a scarce energy source in our country. Excessive use will cause waste of resources and serious pollution. Gasoline or diesel oil will volatilize in the air. In addition, acid and activated clay need to be added when recycling waste engine oil, which itself will pollute the environment, and the effect of dilution is not good, so it cannot be used as a long-term method.
