Description
Technical Field
The invention relates to the technical field of aluminum profiles, in particular to a preparation method of an anti-corrosion electrophoresis extinction aluminum profile.
Background
The extinction aluminum profile is a profile material with strong metal texture, and is more and more widely applied to the fields of buildings, decorations, frames and the like.
The electrophoretic extinction method in the conventional art generally includes the following steps:
the electrophoresis extinction technology comprises the following steps:
the electrophoretic matting technique obtains a matte coating film by adding a matting agent to a high gloss electrophoretic coating. However, the electrophoretic coating obtained by adding the flatting agent is easy to cause uneven gloss because the flatting agent is separated out due to lack of constant migration rate during electrophoretic coating; and the difference of the water washing property or the drying property of the flatting agent and the coating base material, the uneven gloss is easy to generate;
II, extinction technology of the flatting agent:
the extinction method of the fumed silica powder micro-particles comprises the following steps: the ultrafine silicon dioxide powder micro-particles with high porosity are uniformly dispersed in the high-gloss electrophoresis paint, the powder micro-particles uniformly distributed after electrophoresis enable a paint film to have a certain micro-rough surface, and when incident light reaches the uneven surface of the paint film, diffuse emission occurs, namely scattering occurs to generate an extinction appearance. The disadvantages of this method are: 1) the use condition is harsh, and the production cost is high. The main tank and the sub tank of electrophoresis are liable to cause coagulation and precipitation at the places where the circulation is weak. Flow marks are easy to appear on the vertical surface of the section bar, and the horizontal production line is easy to gather on the upper surface of the section bar to cause the difference of the glossiness of the upper surface and the lower surface of the section bar. (the upper surface of the gloss tends to be low and the lower surface tends to be high) the fine silica powder particles have low chemical resistance, particularly poor alkali resistance.
The organic synthetic wax extinction method comprises the following steps: the high-gloss transparent electrophoretic coating is added with polyethylene wax dispersion liquid, after electrophoretic coating, wax is oxidized when the temperature is raised, so that uneven rough surfaces are formed, residues are left in the coating film, an incompatible state is presented, and a high-covering-power extinction appearance is obtained. The disadvantages of this method are: 1) the paint film has poor transparency, the dispersed wax has certain covering property, and the metal feeling of the aluminum profile is reduced. 2) The stability of the coating is poor, and the dispersed wax has the problems of floating in the coating and the like; 3) the wax is scattered by heating in the curing oven, causing coating film contamination and a strong wax odor, and easily causing fire.
In order to achieve better anticorrosion and extinction effects, the invention provides a preparation method of an anticorrosion electrophoresis extinction aluminum profile.
