preparation example Construction

[0072] The preparation technology of conductive spraying powder comprises the following steps:

[0073] (1) Premixing, mixing the raw materials other than aluminum oxide evenly;

[0074] (2) Mixing and extruding, put the uniformly mixed raw materials into the extruder for mixing, the temperature of the melting section is 115±5°C, the temperature of the mixing section is 105±5°C, and the mixture fluid is extruded;

[0075] (3) Cooling, cooling the extruded mixture fluid to room temperature to form a solid mixture;

[0076] (4) Crushing, coarsely crushing the solid obtained in step (3) into particles with a particle size of 0.5-1 cm; then finely grinding it into powder; and sieving to obtain a powder coating with a particle size of 20-35 μm.

[0077] After fine processing and grinding into powder in step (4), add Al2O3 powder before sieving.

[0078] The use method of conductive spray powder comprises the following steps:

[0079] Step 1. Evenly spray the conductive spray pow...

Embodiment 6

[0082] Conductive spraying powder, the difference between embodiment 6 and embodiment 4 is that 10% Al(OH) is also added in the auxiliary agent 3 ;Al(OH) 3 The purity of the powder is greater than 99.5%, the particle size is below 3000 mesh, and the particle size of the prepared powder coating is 20-35 μm.

Abstract

The invention relates to the technical field of powder coatings, in particular to conductive spraying powder and a preparation method thereof, a preparation system of conductive spraying powder and ause method of conductive spraying powder. The raw materials of the conductive spraying powder comprise the following components by weight percentage: 55-65% of polyester resin, 4-6% of a polyester resin curing agent, 0.3% of benzoin or polypropylene wax, 1% of a leveling agent, 0-20% of titanium dioxide, 6-15% of spherical conductive powder and the balance of auxiliary agent. The spherical conductive powder comprises titanium dioxide and stannic oxide with a weight ratio larger than 13:7, and the particle size of the spherical conductive powder is below 0.3 [mu]m; the oil absorption of the spherical conductive powder is lower than 45 g / 100g, and the resistivity of the spherical conductive powder is less than 10 [omega]cm; the auxiliary agent comprises pigments; the raw material also contains 0.3-1% of aluminium oxide powder. The powder prepared from the raw materials has good electric conductivity, weather resistance, salt spray resistance and adhesive force, and is sprayed on the surface of a part to be sprayed, so that the surface is smooth and flat, and the leveling effect is good.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a conductive spray powder, a preparation method, a preparation system and a use method. Background technique [0002] With the development of the Internet, more and more people start to shop online, and logistics companies store more and more courier items. In order to make more reasonable use of space, many courier racks are generally placed in the warehouse. In order to improve the firmness of the courier racks Performance, express delivery racks are generally made of metal materials, and the outer surface of the metal material should be sprayed with paint or paint, so that the metal express delivery racks are not easy to rust. Among them, the paint has a strong smell and is not environmentally friendly; powder coatings are dry solid powders that do not contain organic solvents. It is a new type of coating that uses air as a dispersion medium to evenly coat the surface...
