Problems solved by technology

In addition, due to the high volatility of organic solvents, they are easy to scatter in the air. After being absorbed by the body through breathing, they will also accumulate in the human body and be difficult to decompose, thus causing irreversible damage to the health of producers and users.

preparation example Construction

[0016] A kind of preparation method of water-based spray profile, comprises the following steps:

[0017] Step 1. Carry out washing, degreasing, water washing, conversion coating, two water washings, drying, and removal of the hanging substrate in sequence;

[0018] Step 2. The profiles processed in step 1 are put on the shelves, sprayed with water-based paint, cured, and removed from the shelves in sequence, and finally packaged as finished water-based sprayed profiles;

[0019] The curing temperature in the second step is 180-200°C.

[0020] Calculated according to mass percentage, the proportioning scheme of described water-based paint is as follows:

[0021] Resin paint: 25-30%, alcohol solvent 25-45%, water 25-45%; the sum of the percentages of the above components is 100%.

Abstract

The invention relates to an aqueous spraying profile preparation method, which comprises: 1, sequentially carrying out water washing, degreasing, water washing, film conversion, two water washing and drying on a formed substrate, and discharging out of a frame; and 2, feeding the profile treated in the step 1 onto a frame, spraying an aqueous paint, curing, discharging out of the frame, and packaging to obtain the finished product aqueous spraying profile. According to the present invention, the solvent used for the coating material is the water-soluble alcohol, and the dilution is performed with the water, such that the spraying and the use are safe, and the total solvent consumption is low; and the alcohol is easily decomposed in the human body so as to be discharged, such that the damage caused by the accumulation of the toxic substance in the human body cannot be caused.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of aluminum profiles, and in particular relates to a preparation method of water-based sprayed profiles. Background technique [0002] The surface of traditional aluminum profiles is mostly sprayed with organic solvent-based coatings, and the solvents used in organic solvent-based coatings are toxic thinners with high solubility and volatility. It is absorbed by the skin of workers in the production line, and the solvent accumulated in the body is difficult to decompose. In addition, due to the high volatility of organic solvents, they are easy to scatter in the air, and after being absorbed by the body through breathing, they will also accumulate in the human body and be difficult to decompose, thus causing irreversible damage to the health of producers and users. Contents of the invention [0003] The invention relates to a method for preparing a water-based spray-coated profile, wh...
