The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and combinations particularly pointed out hereinafter.
Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention in a schematic way, and the features in the following embodiments and examples may be combined with each other without conflict.
The invention relates to an aluminum profile spraying process, which comprises the following general process steps:
degreasing → water washing → neutralization → water washing → pure water washing → passivation → sealing → chromizing → drying → electrostatic spraying → baking and curing → packaging.
In the degreasing process, an alkaline degreasing agent for the degreasing agent comprises 15-20 parts of trisodium phosphate, 1-3 parts of nonylphenol polyoxyethylene ether, 1-3 parts of dodecyl alcohol amide phosphate, 1-5 parts of isooctanol polyoxyethylene ether, 1-2 parts of EDTA tetrasodium and 70-80 parts of deionized water, wherein the degreasing temperature is 60-65 ℃, the degreasing time is 5-10min, the degreasing is clean, incomplete degreasing can cause the defects of incomplete passivation film, poor powder layer adhesion, easy shrinkage, pinholes and the like on the surface, a section material cleaned by pure water is put into passivation solution for passivation treatment, a passivation film is formed on the surface of the section material, and then the section material is cleaned by pure water again, and the quality of the passivation film directly influences the quality of powder coating: performing chromizing treatment on the surface of the profile to form a compact chromizing film on the surface of the profile, and then performing heat preservation and drying on the chromizing film for 2-3 hours at the temperature of 60-80 ℃; the surface of the section bar needs to be dried, moisture can not enter a spraying process, the temperature is not more than 130 degrees during drying, so that the passivation film is prevented from losing too much crystal water and becoming loose, the adhesive force of the coating is reduced, and therefore the parameters of surface treatment are selected as follows:
table 1 selection of parameters for surface treatment
In the spraying process, the powder components are selected as follows: 215-230 parts of polyester resin, 30-50 parts of glycerol epoxy resin, 45-52 parts of titanium dioxide, 1-2 parts of dispersing agent, 9-12 parts of curing agent, 3-5 parts of flatting agent, 2-4 parts of nano compound and 10-15 parts of nano kaolin.
The particle size of powder with the particle size of more than or equal to 90 mu m and more than or equal to 10 mu m is too large, the appearance quality of the coated powder is reduced, the orange peel is serious, the powder coating rate is also reduced, the particle size is too small, and the super-absorbing powder is uncharged. The powder layer is controlled to be 60-80 mu m, the phenomena of orange peel, pinholes, flow marks and the like can be generated when the powder layer is too thick, the bottom of the powder layer can be exposed when the powder layer is too thin, and the electric field intensity is in direct proportion to the electric quantity of the powder and is in inverse proportion to the distance between two electrodes. When the distance between the workpiece and the electrode is unchanged, the higher the input voltage is, the stronger the powder wife capacity is, the more the voltage is increased, the less obvious the voltage is, when the distance between the spray gun and the workpiece is too short, spark discharge can be generated, the distance is too far, the powder feeding rate of the powder is reduced, so that the electrostatic voltage is controlled to be 30-90 KV, and the electrostatic spraying distance is 200-250 mm.
TABLE 2 Main parameters of the spraying Process
The process of solidification is through intensification, heat preservation, three stage of heating, if the baking time is not enough, the temperature is low, will cause to paint the crosslinking reaction incomplete, influences the physical and mechanical properties of paining, if the baking time overlength, the high temperature then causes easily to paint phenomenons such as yellow, so curing temperature 200 in curing process, curing time 20min, the curing environment: nitrogen gas.
Compared with the prior art, the invention has the following performances:
