example 1

[0029] Example 1, take 100.0g of industrial waste engine oil, 1.0g of defoamer, 5.0g of talcum powder, 10.0g of liquid paraffin, and 1.0g of sodium dodecylbenzenesulfonate, put them in a reaction kettle, and stir to make the emulsifier evenly dispersed in the In the industrial waste engine oil, release oil is formed, add 800.0g of water to the above release oil in batches, stir until the oil and water form a homogeneous emulsion phase after each addition, and then add the next batch of water until all dilution water is added, and then Stir for 10-15 minutes to form a homogeneous white emulsion, and pack the finished product.

example 2

[0030] Example 2, get 100.0g of industrial waste diesel oil, 1.8g of defoamer, 5.0g of talcum powder, 8.0g of liquid paraffin, and 1.0g of sodium dodecylbenzenesulfonate, put them in a reaction kettle, stir to make the emulsifier evenly disperse into In the industrial waste engine oil, mold release oil is formed. Add 600.0g of water to the above mold release oil in batches. After each addition, stir until the oil and water form a homogeneous emulsion phase, then add the next batch of water until all dilution water is added, and then Stir for 10-15 minutes to form a homogeneous white emulsion, and pack the finished product.

Embodiment example 3

[0031] Example 3: Take 100.0g of industrial waste oil, 5.0g of talcum powder, 10.0g of liquid paraffin, 1.0g of sodium dodecylbenzenesulfonate, and 2.5g of defoamer in a reaction kettle, and stir to make the emulsifier evenly dispersed in the Form release oil in industrial waste engine oil, add 720.0g of water to the above release oil in batches, stir until the oil and water form a homogeneous emulsion phase after each addition, then add the next batch of water until all dilution water is added, and then Stir for 10-15 minutes to form a homogeneous white emulsion, and pack the finished product.

[0032] The defoamers used in the above three examples are commonly used products in the paint industry; the surfactants, defoamers and rust inhibitors used in the production process all need to be controlled within the range of 1-40 HLB.

[0033] Using industrial waste oil as the main raw material, including waste engine oil, waste diesel oil and waste oil, etc., adding a small amount...

Abstract

A high-viscosity antirust concrete demoulding agent and a preparation method thereof. The concrete demoulding agent includes, by weight, 10-40% of industrial waste oil, 20-89% of water, 0.1-5% of a surfactant, 0.1-5% of an emulsifier, 0.1-5% of an antirust agent, and 0.1-5% of a defoamer. The ratio of the surfactant to the emulsifier is 5-1. The concrete releasing agent being high in viscosity, on one hand, achieves recovery of waste materials, and on the other hand, solves environment pollution due to the industrial waste oil. By adding trace amount of the surfactant, the emulsifier and the antirust agent to the industrial waste oil, the components are stirred at room temperature by adding water, thereby producing the concrete demoulding agent which is good in demoulding effect, has stable performance, is zero-pollution and is low in cost. The concrete demoulding agent employs simple production process and equipment and has low production cost and good demoulding effect. A steel mould member has smooth surface and has no surface dust and residual concrete, is convenient to clean and has no rust.

Description

technical field [0001] The invention relates to a high-viscosity antirust concrete release agent and a preparation method thereof. Background technique [0002] The release agent for concrete is a kind of spray (brush) on the working surface of the mold, which plays an isolation role. It can separate the concrete from the mold smoothly when removing the formwork, and can make the concrete surface complete without air bubbles and make the mold smooth and clean. s material. [0003] In recent years, with the increasing number of infrastructure projects such as high-speed railways and subways, the construction of a large number of components has also increased, especially the demand for components that are beautiful, practical, and convenient for construction How to quickly complete the production of components is the key to the concrete industry. As an auxiliary material for components, release agents have been widely used in the concrete industry as early as more than ten y...
