Embodiment 1

[0020] In parts by weight, 26.5 parts of neopentyl glycol oleate, 3.5 parts of pentaerythritol stearate, 1.13 parts of oleyl alcohol polyoxyethylene ether OV-2, 1.15 parts of polyoxyethylene sorbitan monooleate Add Tween 80 into the reaction kettle and heat up to 82°C, stir and mix for 10 minutes to prepare a uniform oily mixture. Add 65.81 parts of water into the reactor and raise the temperature to 82°C, add the oily mixture prepared above while stirring, continue to stir for 20 minutes, and cool to 37°C. Then add 0.5 part of triethanolamine, 0.5 part of triethanolamine borate, 0.5 part of polyether defoamer Dfoam, 0.01 part of acrylic thickener 3800, and continue stirring for 20 minutes. Then add 0.1 part of fungicide BC-25, and continue stirring for 10 minutes to obtain the concrete release agent.

Embodiment 2

[0022] In parts by weight, 26 parts of pentaerythritol oleate, 4 parts of pentaerythritol stearate, 1.4 parts of oleyl polyoxyethylene ether OV-2, 1.5 parts of oleyl alcohol polyoxyethylene ether OV-20 were dropped into the reactor and Raise the temperature to 80°C, stir and mix for 10 minutes to prepare a uniform oily mixture. Then add 65.49 parts of water into the reaction kettle and raise the temperature to 80°C, add the oily mixture prepared above while stirring, continue to stir for 20min and cool to 37°C. Add 0.5 part of triethanolamine, 1 part of acetylene alcohol defoamer DA-725, and 0.01 part of cellulose ether in sequence, and continue stirring for 20 minutes. Then add 0.1 part of fungicide BC-25, and continue stirring for 10 minutes to obtain the concrete release agent.

Abstract

The invention provides an environment-friendly water-based release agent for concrete, and the environment-friendly water-based release agent comprises the following components in percentage by weight: 15-50% of mixed grease, 2-10% of an oily emulsifier, 2-10% of a water-based emulsifier, 0.01-1% of a thickener, 0.5-5% of an antirust agent, 0.1-3% of a defoaming agent, 0.1-1% of a bactericide and45-80% of water. The environment-friendly water-based release agent disclosed by the invention is green, environment-friendly and fast in degradation, does not harm the environment, can greatly improve the surface smoothness of concrete, reduce the number of pores in the surface of the concrete and reduce the ash adhering amount on the surface of a template, and is a concrete water-based release agent with reliable quality..

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environmental-friendly concrete water-based release agent and a preparation method thereof. Background technique [0002] Concrete release agent, as a release agent or lubricant, can effectively reduce the bonding force between concrete and formwork, making concrete easier to demould and reducing concrete appearance defects. [0003] Concrete release agents are generally divided into oil-based release agents and water-based release agents. Oil-based release agents generally include mineral oil, naphthenic oil, and machine oil. Adhesion to concrete surfaces. The water-based release agent emulsifies the oil-based release agent into a water-based emulsion. The amount of painting per unit area is small, and the release performance is good and will not pollute the concrete surface. Therefore, water-based release agents have been widely used in my country. . [0004] ...
