example 1

[0029] A scrub-resistant, graffiti-resistant powder coating, which is made from the following raw materials in parts by weight:

[0030] Hydroxyl resin (hydroxyl value 100mg KOH / g) 50

[0031] Isocyanate 20

[0032] Barium sulfate 25

[0033] Acrylic leveling agent 1.0

[0034] Low surface tension additive 1.0

[0035] Benzoin 0.5

[0036] Antistatic agent 0.5

[0037] Pigment 2.0

[0038] The preparation method of above-mentioned scrub resistance, anti-graffiti powder coating, comprises the following steps:

[0039] (1) All materials are weighed according to the ratio, placed in a high-speed mixer, and mixed for 2 minutes;

[0040] (2) The twin-screw foundation is adopted, the screw arrangement is a standard arrangement, and the extrusion temperature is controlled at 90 o around C;

[0041] (3) The extruded tablet is crushed to 40um particles;

[0042] (4) Particles are sieved with 180 mesh and packed for later use.

Abstract

The invention discloses a scrub-resistant doodle-resistant powder paint which is prepared from the following raw materials in parts by weight: 35-60 parts of hydroxy resin, 20-50 parts of isocyanate, 20-40 parts of inorganic filler, 1-1.5 parts of leveling agent, 0.3-1 part of low-surface-tension assistant, 0.5-0.8 part of benzoin, 0.3-1.0 part of antistatic agent and 0.1-5 parts of pigment. The coated film formed by the paint is imporous and can prevent the paint from permeate into the coating. The product has the advantages of simple formula, excellent chemical resistance, scrub resistance, repeated doodle resistance and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a wipe-resistant and anti-graffiti powder coating and a preparation method thereof. Background technique [0002] At present, more and more people pay more and more attention to the loss caused by malicious graffiti. It not only affects the city appearance and landscape, but also causes huge costs in removing graffiti. It is relatively difficult to reduce the amount of graffiti, so it is of great significance to develop coatings with anti-graffiti properties. Among them, the anti-graffiti powder coating has the advantages of long-lasting wear resistance, easy cleaning of graffiti, cost saving, low pollution, and high product utilization rate, and the production and coating process can achieve zero VOC emissions. Therefore, it has a wide range of applications and industries. prospect. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-sc...
