preparation example Construction

[0042] The preparation method of antifouling paint described in the embodiment all carries out according to the following steps:

[0043] (1) Take kaolin, titanium dioxide and nano-silicon dioxide according to the proportioning ratio, and mix them uniformly to obtain mixed powder;

[0044] (2) Acrylic resin and perchlorethylene resin are weighed by proportioning, after adding solvent, stir evenly, then add the mixed powder that step (1) obtains wherein;

[0045] (3) Add toluene diisocyanate, butyl orthosilicate, antifouling and antibacterial agent, and film-forming aid in sequence to the mixture obtained in step (2), and stir evenly.

[0046] The aluminum profile spraying process in the embodiment is carried out according to the following steps:

[0047] (1) Degreasing: At room temperature, soak the aluminum profile in a phosphoric acid solution with a mass fraction of 80% for 10 minutes, and then place it in 1mol / LNa 2 CO 3 Soak in the solution for 10min;

[0048] (2) Wat...

Embodiment 1-6

[0054] Each component was weighed according to the corresponding data of Examples 1-6 in Table 1, and the antifouling paint of Examples 1-6 was obtained according to the aforementioned method. According to the aforementioned aluminum profile spraying process, the antifouling paints of Examples 1-6 were used for spraying.

[0055] Table 1: Aluminum profile spraying process formula table of embodiment 1-6 Unit: kilogram

[0056]

Embodiment 1

[0067] Compared with Examples 2-4 in Example 1, the compound antifouling compound of zinc pyrithione, (trans) 8-methyl-N-vanillyl-6-nonenamide and methyl nonyl ketone was used The antibacterial agent has better anti-fouling and anti-bacterial effects, and several components have a synergistic effect. When the total amount is the same, the combination effect of using any two groups of them is better.

[0068] In addition, when Example 5 is compared with Examples 1 and 6, when cyclohexyl-1,4-dimethanol monovinyl ether and propylene glycol phenyl ether are used as film-forming aids at the same time, the surface dry time is the shortest, and the paint film formed Better impact resistance and better corrosion resistance.

Abstract

The invention discloses an aluminum profile spraying technology which comprises the following steps: (1), degreasing, (2), washing, (3), anodizing, (5), washing, (6), spraying and (7) curing. A paint film formed with the aluminum profile spraying technology has good impact resistance and good stain-resistant and corrosion-resistant effects, especially has an antibacterial effect and can be widely applied to various occasions such as a plant, a warehouse, a residential building, a hospital, an office building, a shopping mall, a waiting hall and the like as well as instruments.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to an aluminum profile spraying process. Background technique [0002] Aluminum profiles have the advantages of low density, light weight, easy processing, and high recycling rate, so they are widely used in many fields such as construction, building materials, hardware, furniture, ships, and military industry. [0003] In order to make the aluminum profile have better performance, it is usually necessary to spray the aluminum profile. The quality of the spraying process directly affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating, because the best coating film (layer) is adhered to the carefully cleaned surface. [0004] The current aluminum profiles usually have problems such as insufficient impact resistance and poor corrosion resistance. Contents of the invention [0005] In view of the above-mentioned deficiencies in the prior art,...
