Abstract

The invention provides a high-turnover UV-cured aluminum template release agent, which comprises the following components calculated in parts by weight: 6-10 parts of modified acrylic epoxy resin, 1-3 parts of UV monomer diluent, and 0.1-0.6 parts of force accelerator, 0.1-0.6 parts of leveling agent, 0.1-0.4 parts of surface slippery agent, 0.3-0.9 parts of ultraviolet photoinitiator; modified acrylic epoxy resin is made of acrylic acid, hydroxyethyl acrylate, methane It is prepared by modifying epoxy resin with one or more of phthalic acid, phthalic anhydride, trimellitic anhydride, ethylene glycol diglycidyl ether, and epichlorohydrin. The present invention also provides a preparation method of the above-mentioned release agent. The release agent of the present invention is coated on the aluminum alloy formwork, and is irradiated with ultraviolet light at room temperature to make it solidify into a film. It is used in the concrete pouring process. The demoulding quality of the concrete is good, the surface is smooth and pollution-free, and there is no concrete on the surface of the formwork. Residue, the template can be used up to 100 times after one application of the release agent, prolonging the service life of the template.

Description

technical field

[0001] The invention belongs to the field of auxiliary agents for building materials, and in particular relates to a high-turnover UV-cured aluminum template release agent and a preparation method thereof. Background technique

[0002] Concrete molding needs to be fixed with the help of templates, and the templates will be removed after the concrete has formed a certain strength. In concrete pouring, if the product is connected with the formwork, it will not only easily damage the product, but also cause difficulty in removing and cleaning the formwork, high labor intensity and low production efficiency.

[0003] Concrete release agent is a preparation that can reduce or prevent the adhesion between concrete and the formwork surface, and there are many types of release agents currently in use. According to the appearance, the release agent can be divided into solid, solution, emulsion and paste; according to the effect, it can be divided into one-time and lo...
