Problems solved by technology

[0003] At present, most of the appearance of sand grains on the market is obtained by adding sand grain agents, and most of the common indoor matt flat powder coatings are obtained by adding chemical matting agent XG603-1A, which do not show sand grains. Moreover, the scratch resistance of the surface is poor, which may cause irreversible damage to the product during packaging and transportation, and the surface feels relatively "cold", and the fit with the human body is poor

Abstract

The invention discloses an indoor lightless flat sand-textured powder coating having skin tactility and specially used for IT products. The powder coating comprises carboxyl polyester resin, epoxy resin, an acrylic flatting agent, a leveling agent, benzoin, a brightener, a special toughening agent, wear-resistant wax, a catalyst, extinction barium sulfate, calcium carbonate and carbon black. The flat sand-textured powder coating having skin tactility is prepared by matching the carboxyl polyester resin, the acrylic flatting agent and the special toughening agent, shows an extremely fine sand texture state and a strong sand feeling under a naked eye viewing condition, but has a flat tactility and strong soft skin tactility, so the powder coating is suitable for being applied to IT electronic information products and indoor furniture products, and the soft skin tactility of the powder coating is close to the fit degree, the comfort and the softness of human skins; and the powder coatingalso has excellent mechanical properties and excellent scratch resistance under a low gloss condition, and is functional new functional having the advantage of convenience in material drawing, convenience in preparation and low cost.

Description

technical field [0001] The invention relates to the field of chemical powder coatings, in particular to an indoor matte plane sand grain skin touch powder coating specially used for IT products. Background technique [0002] Powder coating is a 100% solid powder that does not contain organic solvents. It is different from oil-based paints and water-based paints. It does not use solvent or water as a dispersion medium when coating, but uses air as a dispersion medium to evenly coat the workpiece. The surface is a new type of environmentally friendly paint that forms a special-purpose coating film after heating. Powder coating has the characteristics of no VOC, environmental protection, energy saving, high construction efficiency and wide application range. [0003] At present, most of the appearance of sand grains on the market is obtained by adding sand grain agents, and most of the common indoor matt flat powder coatings are obtained by adding chemical matting agent XG603-...
