Corrosion-resistant concrete water-based release agent and preparation method thereof

Abstract

The invention relates to the field of release agents, and particularly discloses an anticorrosive concrete water-based release agent and a preparation method thereof. The release agent is prepared from the following raw materials: 10 to 20 parts of tall oil lubricant; 5-8 parts of an imidazoline quaternary ammonium salt preservative; 5 to 10 parts of a nonionic surfactant; 3-6 parts of an anionic surfactant; 1-4 parts of an emulsifier; 3-5 parts of a thickening agent; 6-9 parts of paraffin; 40 to 70 parts of water; the preparation method comprises the following steps: mixing the tall oil lubricant, the paraffin and the emulsifier, adding the mixture into water, heating to 40-50 DEG C, and stirring at a constant temperature for 30-40 minutes to obtain a solution a; adding a nonionic surfactant, an anionic surfactant and an imidazoline quaternary ammonium salt preservative into the solution a, and continuously stirring for 30-40 minutes to obtain a solution b; and finally, adding the thickening agent into the solution b, and continuously stirring for 1-1.5 hours to obtain the anticorrosive concrete water-based release agent. The mold has the advantage of good demolding effect.

Description

technical field [0001] The present application relates to the field of mold release agents, and more particularly, to a water-based mold release agent for anti-corrosion concrete and a preparation method thereof. Background technique [0002] A release agent is a functional substance between the mold and the finished product. The use of release agents is crucial in concrete construction, and in the process of pouring concrete prefabricated components or prefabricated products, formwork or moulds must be used. In order to make the hardened concrete easy to demould without damaging the product or formwork, a layer of release agent is often applied to the formwork or formwork. [0003] With the increase in the types of concrete and formwork, there are more and more types of release agents. At present, concrete release agents are classified into different categories. According to the preparation process, they can be divided into saponification, emulsification, solvent, synthesi...

AI Technical Summary

Problems solved by technology

Generally, there is a problem of emulsification effect when using emulsified release agent technology. When used, the release agent is easy to delaminate and unstable, and the effect is relatively poor. Compound release agents are often used in the market

[0004] In view of the related technologies mentioned above, the inventor believes that there are the following defects: the demoulding effect of the composite mold release agent is poor, so that the formwork and the product are bonded, and the surface and performance of the concrete product will be destroyed during demoulding.
