Problems solved by technology

However, increasing the amount of addition will make the coating effect worse, the resin leveling will become weaker, and pinholes will appear, that is, the resin cannot infiltrate certain areas and form circular holes
If mica is added to the twin-screw, the leveling property of the resin will be improved, but due to the shearing action of the twin-screw, the structure of the mica will be severely damaged, and the reflective effect will be weakened sharply
Therefore, there are certain difficulties in improving the surface gloss

Abstract

The invention discloses a high-gloss polypropylene-based powder coating as well as a preparation method and application thereof. The polypropylene-based powder coating is prepared from the following components in parts by mass: 90-100 parts of polypropylene resin, 2-8 parts of a compatilizer, 0.5-2 parts of an antioxidant, 0.1-1 part of a light stabilizer, 0.01-2 parts of toner, 0.2-4 parts of mica powder, 0.01-0.2 part of ultrathin metal powder and 0.1-1 part of an anti-caking agent. The ratio of the width to the thickness of the ultrathin metal powder is larger than 100. According to the invention, in order to improve the surface gloss of plastic dipping and rubber coating of the polypropylene powder, through the combined action of the ultrathin metal powder and the mica powder, the glossiness of the polypropylene-based powder coating is improved without reducing the plastic dipping manufacturability of the polypropylene-based powder coating, and the polypropylene-based powder coating with high gloss and good plastic dipping effect is prepared.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic powder coating materials, in particular to a high-gloss polypropylene-based powder coating, its preparation method and application. Background technique [0002] The bowl basket is the rack in the dishwasher that is used to drain the dishes after washing. There are mainly two types of stainless steel or rubber-coated steel. Compared with stainless steel bowl baskets, bowl baskets in the form of steel rubber-coated bowls are cheaper, and the coating on the surface can cushion impacts and reduce the chance of dishes being broken by impact. The rubber covering on the surface of the bowl basket is usually realized by dipping. [0003] The plastic powder used for dipping of bowls and baskets usually has two categories: low-melting point polyamide and polypropylene. Polypropylene has received widespread attention due to its relatively cheap price and better water resistance, salt resistance, an...
