Special water-based release agent for prefabricated buildings

Abstract

The invention relates to the technical field of the construction industry, especially to a special water-based release agent for prefabricated buildings. The special water-based release agent is characterized in that a component released by using the special water-based release agent is non-sticky and easy to release, the surface of a released mold is clean and easy to wash, the mold is not easy to rust, the surface color of a component is uniform, freezing during winter construction is avoided, rain-proofness is realized during outdoor construction, use cost is reduced and practicability is improved. The release agent comprises the following components in percentage by weight: 3-10% of resin, 30-50% of base oil and 16.5-53% of additives, wherein the additives comprise 3%-10% of barium petroleum sulfonate (T701), 3%-7% of fatty alcohol-polyoxyethylene ether (JFC), 2%-5% of triethanolamine, 1%-6% of ethylene glycol, 0.5%-1% of a defoaming agent, 5%-10% of Op-7, 1%-10% of EO-100 and 1%-4% of water.

Description

technical field [0001] The invention relates to the technical field of construction industry, in particular to a special water-based release agent for prefabricated buildings. Background technique [0002] As we all know, the release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and will not be dissolved when in contact with the chemical components of different resins (especially styrene and amines). The release agent also has heat and stress resistance, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the processed part, and does not hinder painting or other secondary processing operations. Therefore, in the assembled During the construction process of construction projects, the amount of release agent used is large. With the continuous increase of new structures, new processes and new materials in construction projects, the performance requirements for...

[0002] As we all know, the release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and will not be dissolved when in contact with the chemical components of different resins (especially styrene and amines). The release agent also has heat and stress resistance, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the processed part, and does not hinder painting or other secondary processing operations. Therefore, in the assembled During the construction process of construction projects, the amount of release agent used is large. With the continuous increase of new structures, new processes and new materials in construction projects, the performance requirements for release agents are also getting higher and higher. Existing bridge buildings, residential buildings, etc. Prefabricated buildings in construction and other fields generally use tangible release agents, but oil-based release agents are found to be easy to stick to the mold, difficult to clean the mold after demoulding, easy to rust, and uneven color on the demoulding surface of components. , Easy to freeze, making construction difficult in winter, afraid of rain during outdoor construction, and high cost of use, which greatly reduces its practicability
