Abstract

The invention discloses a concrete mold release agent, and belongs to the field of building materials. The concrete mold releasing agent disclosed by the invention comprises the following components in part by weight: 15 to 40 parts of polyvinyl alcohol, 10 to 15 parts of epoxy resin, 15 to 25 parts of microcrystalline wax, 1 to 10 parts of nonylphenol polyoxyethylene ether, 1 to 5 parts of rosin, 1 to 2 parts of tri-butyl-phosphate, 1 to 8 parts of sodium alginate, 1 to 6 parts of an anti-rust agent, and 200 to 800 parts of water. The concrete mold release agent has a good mold release effect; the concrete is smooth after a mold is released; the service life of a steel mold can be prolonged; the concrete mold release agent has an anti-rust performance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete release agent. Background technique [0002] Urbanization drives the steady development of the construction industry, and the requirements for building materials are getting higher and higher. Concrete release agent is one of the important elements of building materials. However, the existing release agents have poor demoulding effect, are difficult to remove on the formwork, and are not effective in maintaining the formwork, which affects the construction efficiency and increases the construction cost. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of the prior art and provide a concrete release agent. [0004] The technical solution adopted in the present invention is a concrete release agent, including polyvinyl alcohol, epoxy resin, microcrystalline wax, nonylphenol polyoxyethylene ether, rosin, tributyl phospha...
