Rust-resistant concrete mold release agent and preparation method thereof

Abstract

The invention discloses a rust-resistant concrete mold release agent and a preparation method thereof. The rust-resistant concrete mold release agent comprises the following components as raw materials in parts by weight: 50-55 parts of modified glycerin, 25-30 parts of coconut acid monoethanolamide, 0.3-0.5 part of zinc dialkyl dithiophosphate, 8-10 parts of rosin resin, 0.4-0.6 part of t-butyl acrylate, 2-3 parts of sodium tripolyphosphate, 1.5-1.8 parts of lauryl diethanolamide, 6-8 parts of purified benzene emulsion, 0.3-0.5 part of sodium tripolyphosphate, 0.1-0.2 part of sodium benzoate and 300-330 parts of deionized water. By adopting modified glycerin as main base oil, the difficulty of emulsification is decreased; the rust-resistant agent and multiple additives are added, so that the rust-resistant concrete mold release agent has good rust resistance, high temperature resistance and the like on the surface of a concrete member and the concrete member has smooth surface, the secondary treatment is not needed and the construction cost is decreased.

Description

technical field [0001] The invention provides a concrete release agent, in particular to an antirust concrete 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 release agent The mold material is made of engine oil or waste engine oil plus diesel oil. In the long-term construction of water conservancy, hydropower, highways, railways and other projects, it is found that the use of waste engine oil to paint the formwork will pollute the concrete surface and cause different degrees of pollution to the environment; but The existing release agent has poor demoulding effect, is difficult to remove on the formwork, and is not e...

The traditional release agent The mold material is made of engine oil or waste engine oil plus diesel oil. In the long-term construction of water conservancy, hydropower, highways, railways and other projects, it is found that the use of waste engine oil to paint the formwork will pollute the concrete surface and cause different degrees of pollution to the environment; but The existing release agent has poor demoulding effect, is difficult to remove on the formwork, and is not effective in maintaining the formwork, which affects the construction efficiency and increases the construction cost
