Smooth color master batch used for PET and preparation method thereof

Abstract

The invention discloses smooth color master batch used for PET and a preparation method thereof. The smooth color master batch comprises following components by weight: 30-70% of a carrier, 4-10% of an anti-blocking agent, 10-30% of a smoothing agent, 10-20% of pigments, 1-5% of a dispersant, 0.1-1% of a coupling agent and 0.1-1% of an antioxidant. Beneficial effects of the color master batch and the preparation method are that: compared with the prior art, the color master batch is applied in PET film or film products, and the color master batch has characteristics of good anti-blocking smoothing effects, even coloring, good dispersibility, high concentration, simple operation, using convenience, capability of improving performances and the processing environment of products, and the like.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a smooth color master batch for PET and a preparation method thereof. Background technique

[0002] Polyethylene terephthalate (PET) is a crystalline polymer, commonly used in fibers, extruded films and sheets, blow molding, etc., because of its good toughness, mechanical strength and excellent transparency, it is widely used It is used in cosmetics, food, electronics, toys, printing and other industries, but the smoothness of PET alone is relatively poor, and about one-third of the cases need to be used for coloring. Contents of the invention

[0003] The object of the present invention is to provide a smooth color masterbatch for PET with good smooth effect, high coloring quality and convenient use and a preparation method thereof.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a smooth masterbatch for PET, and i...
