Embodiment 1

[0016] The anti-precipitation masterbatch is composed of the following components in parts by weight: 15-50 parts of polyethylene, 5-50 parts of pigment, 10-30 parts of auxiliary agent, and 5-10 parts of filler. This composition prevents its precipitation in plastic products.

[0017] Experimental data of n-hexane evaporation residue

[0018] Test conditions: 23 degrees Celsius at room temperature. Time: Soak for two hours and dry for 2.5 hours to cool.

[0019]

[0020] The specific test data is the comparison of the evaporation residue after the melting of n-hexane flux. Ordinary common color masterbatches may be as high as 400 mg per liter, and the excellent anti-separation masterbatch is as low as 30 mg per liter.

Embodiment 2

[0022] The anti-precipitation color masterbatch is composed of the following components in parts by weight: 25-50 parts of polyethylene, 5-40 parts of pigment, 10-25 parts of auxiliary agent, and 5-8 parts of filler. This component has more outstanding oil resistance on the basis of preventing precipitation.

Embodiment 3

[0024] The anti-precipitation masterbatch is composed of the following components in parts by weight: 15-30 parts of polyethylene, 10-50 parts of pigment, 20-30 parts of auxiliary agent, and 7-10 parts of filler. On the basis of anti-precipitation, this component further highlights the solvent resistance.

Abstract

The invention relates to the technical field of masterbatches, and in particular relates to an anti-precipitation type masterbatch. The masterbatch is composed of the following components in parts byweight: 15-50 parts of polyethylene, 5-50 parts of a pigment, 10-30 parts of an auxiliary agent, and 5-10 parts of a filler. The masterbatch provided by the invention does not contain small molecularsubstances, the oil resistance and the solvent resistance of the masterbatch are increased, the migration resistance of the masterbatch is improved, the phenomenon of precipitation in plastic productscannot occur, and therefore a plastic product which adds and uses the masterbatch can reach a food grade.

Description

technical field [0001] The invention relates to the technical field of color masterbatches, in particular to anti-precipitation color masterbatches. Background technique [0002] The color masterbatch is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant, and has good compatibility with the material to be colored sex. However, the existing color masterbatch will produce precipitation in plastics, so the safety of plastic products using this color masterbatch cannot be guaranteed. Contents of the invention [0003] In order to overcome the deficiency that the existing color masterbatch can be precipitated in plastics, the present invention provides an anti-precipitation color masterbatch. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a kind of anti-precipitation color masterbatch, wh...
