Definitions
- the invention relates to the technical field of concrete release agents, in particular to a concrete release agent and a preparation method thereof.
- Concrete mold release agents are generally divided into oil-based mold release agents and water-based mold release agents.
- Oil-based mold release agents generally include mineral oil, naphthenic oil, motor oil, etc., with good water resistance but large amount of brushing per unit area, which is easy to contaminate concrete and reduce Adhesion of concrete surfaces.
- the water-based mold release agent is to emulsify the oil-based mold release agent into a water-based emulsion. The amount of brushing per unit area is small, and the mold release performance is good and will not pollute the concrete surface. Therefore, the water-based mold release agent has been widely used in my country. .
- a long-acting concrete release agent suitable for steel form and its preparation method discloses a long-acting concrete release agent suitable for steel form and its preparation method, and its publication date is 2020 On February 18, it includes vegetable oil, film-forming aids, complex emulsifiers, stabilizers, rust inhibitors and water, with long-chain alkyl silane coupling agents and aminopropyltriethoxysilane as the main film-forming agents
- the silicon-oxygen bond in the molecular structure of the additive is hydrolyzed to hydrolyze the silicon-hydroxyl group to interact with the active hydroxyl group of the steel to form a chemical bond, forming a chemical adsorption film on the surface of the steel, adhesion Force cavity, forming a solid film, so as to play an anti-corrosion effect.
- the present invention provides a concrete release agent, which comprises:
- An emulsified oil comprises a heat transfer oil and a co-emulsifier, and the co-emulsifier is diisobutyl dibasic acid;
- a rust inhibitor is selected from a mixture of one or more of fatty acids, alcohol amines, sodium nitrite, and sodium carbonate.
- the diisobutyl dibasic acid is at least one of diisobutyl succinate, diisobutyl glutarate or diisobutyl adipate;
- the fatty acid is preferably oleic acid, etc.
- the alcohol amine is preferably triethanolamine, etc.
- the waste heat-conducting oil is the HW08 waste mineral oil hazardous waste in the National Hazardous Waste List, although it can be used as fuel oil to be supplied to refineries for combustion, the environmental pollution is large and the waste of resources is serious; the heat-conducting oil used in the present invention can be waste gas. Thermal oil.
- the following components are further included: 3-10 parts of emulsifier, 0.1-3 parts of thickener, 0.1-2 parts of defoamer, 0.1-2 parts of preservative and 50-85 parts water.
- the emulsifier is sorbitan monostearate, polyoxyethylene sorbitan trioleate or polyoxyethylene sorbitan tristearate at least one.
- the thickener is attapulgite.
- the defoamer is a polyether defoamer.
- the preservative is one of phenol, pentachlorophenol or sodium benzoate.
- the invention provides a preparation method of a concrete release agent, comprising the following steps:
- emulsified oil is obtained by mixing and stirring the emulsified heat-conducting oil and a co-emulsifier, and the co-emulsifier is diisobutyl dibasic acid;
- the emulsified oil is made into a mold release agent, and an auxiliary agent is added to the emulsified oil, the auxiliary agent includes a rust inhibitor, and the rust inhibitor is selected from fatty acids, alcohol amines, sodium nitrite, sodium carbonate A mixture of one or more of them.
- the present invention also provides a kind of preferred preparation method, and the concrete steps are as follows:
- Step 1 Mix water, sorbitan monostearate, polyoxyethylene sorbitan trioleate, polyoxyethylene sorbitan tristearate and waste heat-conducting oil according to the aforementioned ratio, Stir at 2800r/min for 30min to obtain pre-emulsified oil;
- Step 2 add a certain proportion of diisobutyl dibasic acid to the pre-emulsified oil obtained in step 1, and stir for 30min under the condition of 2800r/min to obtain complete emulsified oil;
- Step 3 adding a rust inhibitor, a thickener, a defoaming agent, and a preservative to the fully emulsified oil obtained in the second step, and stirring evenly to obtain a concrete release agent.
- the preparation method of the rust inhibitor is:
- the present invention provides the concrete release agent prepared by the above-mentioned preparation method.
- heat-conducting oil as the main film-forming material has the advantages of excellent thermal conductivity and thermal cracking resistance, which can quickly conduct local heat of the concrete, improve the rebound strength, and avoid the formation of surface temperature cracks during the concrete forming process;
- the co-emulsifier can improve the film-forming mechanism of the emulsion and help to form the film. After the film is formed, the co-emulsifier volatilizes, which will not affect the characteristics of the release agent, and can effectively shorten the drying and film-forming time of the release agent.
- the concrete release agent of the present invention has good release performance and can effectively reduce apparent quality problems such as voids and air bubbles on the concrete surface.
- the present invention also provides the following examples and comparative examples:
- a commercially available concrete release agent of the LW-201 model was used.
