Problems solved by technology

However, these release agents have low adhesion to the surface of the aluminum plate. When pouring concrete to impact the surface of the formwork, the release agent will delaminate from the surface of the aluminum plate and fail, often failing to achieve the desired effect. Therefore, recoating is often required, which is time-consuming and labor-intensive.
[0004] In order to ensure the demoulding quality of the concrete during the construction process, the release agent or release oil will be re-applied after almost every layer of demoulding, but the surface of the formwork often appears sticky after demoulding, resulting in uneven concrete surface and depressions , pothole

Abstract

The invention relates to an aluminum template release paint and a preparation method thereof. The aluminum template release paint of the present invention is mainly made of the following raw materials in parts by weight: 100-110 parts of methyl methacrylate, 40-50 parts of butyl acrylate, 5-10 parts of methacrylic acid, diethylene glycol diethylene glycol 1-5 parts of methacrylate, 5-10 parts of hexamethylene diisocyanate, 3-5 parts of zinc acrylate, 2-5 parts of azobisisoheptanonitrile, 10-20 parts of fluorocarbon resin, 120 parts of butyl acetate ~200 copies. The beneficial effects of the present invention are: the present invention has high hardness and compact surface, high adhesion with aluminum plate, good alkali resistance, good impact resistance, good aging resistance, low surface energy, good water resistance and stain resistance The high-performance release-integrated template coating; sprayed on the surface of the aluminum template, the thickness is controlled below 20 microns, and in terms of construction, one painting can ensure more than 10 demoulding turnover times.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an aluminum template release paint and a preparation method thereof. Background technique [0002] Architectural aluminum formwork has gradually developed into a very important part of building formwork. Aluminum formwork is often affected by concrete during use, especially during demoulding, such as adhesion or adhesion with part of the concrete. On the one hand, it affects the smoothness of the concrete surface. On the other hand, it increases the difficulty of cleaning the template, which leads to damage or corrosion of the template surface, which affects the effect of the next use of the template. When leaving the factory, the surface of the aluminum formwork will be coated with a layer of release agent to protect the aluminum plate. Before pouring concrete on site, release paint or release oil will be painted, but after 3 to 5 turnovers, it must be repainted, which w...
