AI Technical Summary

Problems solved by technology

The product has no obvious technical requirements, and the quality control threshold is low, which leads to poor appearance quality of the produced concrete, and even affects the interface between the steel bar and the concrete, affecting the structural strength of the concrete
In addition, the emulsion release agent widely promoted in the market has poor film-forming properties with the formwork, which affects the release effect and causes corrosion to the steel formwork

Embodiment 1

[0036] A kind of mold release agent for novel concrete products, is characterized in that, comprises following components by weight parts:

[0037] White oil: 20 parts;

[0038] Rust inhibitor: 1 part;

[0039] High molecular polymer: 0.5 parts;

[0040] Deionized water: 51 parts;

[0041] Emulsifier: 19 parts;

[0042] Further, the high molecular polymer is cross-linked polyacrylate.

[0043] Further, the rust inhibitor is triethanolamine oleic acid soap.

[0044] Further, the emulsifier is ethoxylated isotridecanol.

[0045] The invention is based on white oil, and uses ethoxylated isotridecanol and cross-linked polyacrylate as the main film-forming substance of the release agent, so that the release agent has strong adhesion, good release effect, and erosion resistance , temperature resistance, can be used many times and so on.

Embodiment 2

Abstract

The invention provides a novel release agent for concrete products and a preparation method thereof. The novel release agent comprises the following components in parts by weight: 20-40 parts of white oil; 1-3 parts of a corrosion inhibitor; 0.5-1.0 part of a high-molecular polymer; 51-74.5 parts of deionized water; and 15-27 parts of an emulsifier; wherein the emulsifier is one or a mixture of two of ethoxylated isotridecanol and sorbitan oleate. The release agent is good in film-forming property, the release effect is obviously improved compared with a traditional release agent, most importantly, compared with the traditional oil-in-water type release agent, the release agent does not have the rusting effect on a steel formwork, spraying construction can be conducted, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a novel release agent for concrete products and a preparation method thereof. Background technique [0002] The production of traditional concrete products usually uses recycled waste engine oil, mineral oil, vegetable oil, and even some purified kitchen waste oil as a release agent. There are no obvious technical requirements for the product, and the quality control threshold is low, which leads to poor appearance quality of the produced concrete, and even affects the interface between the steel bar and the concrete, affecting the structural strength of the concrete. In addition, the emulsion release agent widely promoted in the market has poor film-forming properties with the formwork, which affects the release effect and causes corrosion to the steel formwork. Contents of the invention [0003] In view of this, the present invention provides a novel release...
