Problems solved by technology

However, with the time of use, the surface of the aluminum-plastic panel is polluted by rainwater and slightly acidic substances in the air, or in the case of artificial pickling, the surface of the aluminum-plastic panel will be bloomed and aging will be accelerated.
[0003] At present, there are mainly two ways to renovate aluminum-plastic panels on the market. One is to directly remove the old panels and re-pave new aluminum-plastic panels; the other is to renovate and spray fluorocarbon paint. The specific construction method is: surface grinding- Primer spraying-fluorocarbon paint spraying, this kind of coating is mainly two-component (main agen

Abstract

The invention discloses an aluminum-plastic panel refurbishing facing paint which is selected from the following components in parts by weight: a component A and a component B. The component A comprises predetermined parts by weight of white cement, quartz powder and cellulose ether. The component B is prepared from the following components in parts by weight: 6.9-8.1 parts of water, 70-82 parts of polyacrylic emulsion, 6.92 parts of titanium dioxide slurry, 0.04-0.06 part of a thickening agent, 0.1-0.15 part of a buffering agent, 0.30-0.40 part of a defoaming agent, 0.15-0.25 part of a wetting agent, 0.1-0.2 part of a water retaining agent, 0.8-1.0 part of a dispersing agent and 6.0-7.0 parts of a film-forming agent. The components above are stirred and mixed to prepare the aluminum-plastic panel refurbishing facing coating, and the aluminum-plastic panel refurbishing facing coating is coated on the surface of a base body in a rolling manner to finish construction. The coating is freeof gel, peeling and falling off under the condition of 100 DEG C (+/-2), and is easy to construct.

Description

technical field [0001] The invention relates to the technical field of paint for renovation of aluminum-plastic panels, in particular to a paint for renovation of aluminum-plastic panels and a construction method thereof. Background technique [0002] The progress of modern society is getting faster and faster, and the decoration of building exterior walls is full of tricks. Its decorative, environmentally friendly and functional choices also stimulate more and more people to have different design concepts for exterior walls. Among them, building curtain walls are used Aluminum-plastic composite board (abbreviated as aluminum-plastic board) is also one of the choices. It is light and convenient, high-strength, diverse in color, and does not require long-term maintenance. It is very popular among the people. However, with the time of use, the surface of the aluminum-plastic panel is polluted by rainwater and slightly acidic substances in the air, or in the case of artificial ...
