Abstract
The invention discloses a concrete water-based releasing agent produced by using drainage oil and a preparation method thereof. The releasing agent is prepared from the following raw materials by weight percent: 8%-22.5% of drainage oil, 0.5%-3.6% of a compound emulsifier, 1%-10% of an additive, 1%-3.2% of a stabilizer and 60%-87% of water, wherein the emulsifier is the compound emulsifier comprising an anionic emulsifier and a nonionic emulsifier, the anionic emulsifier comprises one or multiple of stearic acid and sodium dodecylbenzene sulfonate, and the nonionic emulsifier comprises one or multiple of fatty acid polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty acryl alcohol amine, Span and Tween. After forming a film, the water-based releasing agent plays a role in separation of the concrete and a template. The water-based releasing agent is used for replacing an existing frequently-used emulsification machine oil releasing agent, is odorless and tasteless and has a good using effect; due to the adoption of the releasing agent, the apparent quality of the concrete is improved, and the turnover utilization rate of the template is also increased; and the production cost of the releasing agent is reduced.
Description
[0001] technical field [0002] The invention belongs to the comprehensive utilization of waste oil waste, in particular to a water-based release agent for concrete produced from waste oil and a preparation method thereof. Background technique [0003] According to expert estimates, the annual output of waste oil in my country has reached 12 million tons, of which 3.5 million tons are returned to the dining table, which seriously endangers the health of the people. The Supreme People's Court, the Supreme People's Procuratorate, and the Ministry of Public Security jointly issued the "Notice on Severely Punishing "Gutter Oil" Criminal Activities in accordance with the Law." [0004] While cracking down on "gutter oil" crimes, technology companies are also offering suggestions on the waste utilization of gutter oil, hoping to turn waste into treasure and return the application of gutter oil to the right track. Shanghai Environmental Protection Enterprise has successfully develo...
