Problems solved by technology

The traditional demoulding material is engine oil or waste engine oil plus diesel oil. In the long-term construction of water conservancy and hydropower, highways, railways and other projects, it has been found that using waste engine oil to paint the formwork will pollute the concrete surface and cause varying degrees of damage to the environment. Pollution; the use of finished engine oil needs to be diluted with diesel oil, so it is difficult to control the proportion and brushing effect on site, and the use cost is high, and there are also different degrees of pollution; the use of salad oil is better for brushing, but the cost is too high. Food grade oil is not easy to control
All kinds of water-soluble release agents and oil-soluble release agents currently on the market are not ideal in actual use

Embodiment 1

[0018] The environmentally friendly oily emulsified release agent of the present embodiment is made of the following raw materials in mass percentage: waste engine oil 30%, mineral oil 20%, polyoxyethylene ether 0.5%, triethanolamine 0.05%, water-based silane coupling agent (KH- 550) 0.2%, and the balance is deionized water.

[0019] The preparation method of the environmentally friendly oily emulsified release agent in this example is: dissolve 200g of water-based silane coupling agent (KH-550) in 3800mL of deionized water to prepare a silane coupling agent solution with a mass concentration of 5%, and then dissolve 30kg Add waste engine oil, 20kg mineral oil, 500g polyoxyethylene ether, 50g triethanolamine and the prepared silane coupling agent solution to the reactor in sequence, stir and react at 70°C for 30min, then add 45.45kg deionized water into the reactor, Continue to stir and react for 30 minutes, and finally filter to remove solid insolubles to obtain an environmen...

Embodiment 2

[0021] The environmentally friendly oily emulsified release agent of this embodiment is made of the following raw materials in mass percentage: 40% waste oil, 20% mineral oil, 0.5% polyoxyethylene ether, 0.05% triethanolamine, water-based silane coupling agent (KH- 560) 0.2%, and the balance is deionized water.

[0022] The preparation method of the environment-friendly oily emulsified release agent of this example is: pour 200g of water-based silane coupling agent (KH-560) into 3800mL deionized water to prepare a silane coupling agent solution with a mass concentration of 5%, and then mix 40kg Waste oil, 20kg of mineral oil, 500g of polyoxyethylene ether, 50g of triethanolamine and the prepared silane coupling agent solution were sequentially added to the reactor, stirred and reacted at 80°C for 20min, and then 35.45kg of deionized water was added to the reactor. Continue to stir and react for 60 minutes, and finally filter to remove solid insolubles to obtain an environmenta...

Embodiment 3

[0024] The environmentally friendly oily emulsified release agent in this example is made of the following raw materials in mass percentage: 50% mineral oil, 0.5% polyoxyethylene ether, 0.05% triethanolamine, 0.2% water-based silane coupling agent (KH-570), The balance is deionized water.

[0025] The preparation method of the environment-friendly oily emulsified release agent of this example is: pour 200g of water-based silane coupling agent (KH-570) into 3800mL deionized water to prepare a silane coupling agent solution with a mass concentration of 5%, and then mix 50kg Mineral oil, 500g of polyoxyethylene ether, 50g of triethanolamine and the prepared silane coupling agent solution were added to the reaction kettle in sequence, stirred and reacted at 60°C for 40 minutes, then 45.45kg of deionized water was added to the reaction kettle, and stirred and reacted for 40 minutes , and finally filtered to remove solid insolubles to obtain an environmentally friendly oily emulsifi...

Abstract

The invention discloses an environment-friendly oily emulsion release agent. The environment-friendly oily emulsion release agent is prepared from the following raw materials in percentage by weight: 50-60% of oily substance, 0.2-0.6% of polyoxyethylene ether, 0.05-0.1% of triethanolamine, 0.2-0.5% of a water-based silane coupling agent, and the balance of deionized water, wherein the oily substance is mineral oil, or used oil and mineral oil, or gutter oil and mineral oil. The invention further discloses a preparation method of the release agent. The release agent has the oil-water compatible characteristic, solves the problems of incompatibility of oil and water and layering, can be diluted with water for long-time preservation without layering, avoids the pollution to concrete surface by using the used oil, prevents the corrosion of the water-soluble release agent to a steel template, and avoids diluting engine oil by using diesel in the past. The environment-friendly oily emulsion release agent is milk-white liquid capable of being sprayed and coated, is conveniently used, suitable for various concrete templates, and colorless and transparent when being coated on the templates, and has good adhesiveness.

Description

technical field [0001] The invention belongs to the technical field of concrete release agents, and in particular relates to an environment-friendly oily emulsified release agent and a preparation method thereof. Background technique [0002] Concrete release agent is also called concrete release agent or release lubricant. It is a substance that is applied to the inner wall of the formwork to lubricate and isolate, so that the concrete can be smoothly separated from the formwork when the formwork is removed, and the shape of the concrete is kept intact. The traditional demoulding material is engine oil or waste engine oil plus diesel oil. In the long-term construction of water conservancy and hydropower, highways, railways and other projects, it has been found that using waste engine oil to paint the formwork will pollute the concrete surface and cause varying degrees of damage to the environment. Pollution; the use of finished engine oil needs to be diluted with diesel oi...
