Embodiment 1

[0011] Embodiment 1: prepare 100kg plastic moisture-removing coloring masterbatch

[0012] Take 33 kg of calcium oxide, 21 kg of carbon black (pigment black), 24 kg of paraffin, and 22 kg of high-density polyethylene resin for pre-mixing, then add it to a kneader with a rotation speed of 500-1800r / min and knead for 40 minutes, and knead until the Finally, the uniformly stirred mixture is put into the extruder with the temperature of the main engine at 100-300°C for extrusion, the die surface is eagerly cut, pelletized, cooled, and packaged to make the desired moisture-removing coloring masterbatch.

Embodiment 2

[0013] Embodiment 2: prepare 100kg plastic moisture-removing coloring masterbatch

[0014] Take 40 kg of tin oxide, 10 kg of sunfast scarlet, 30 kg of polyethylene wax, and 20 kg of linear low-density polyethylene resin for pre-mixing, then add it to a kneader with a speed of 500-1800r / min and knead for 30 minutes, and knead to Finally, the uniformly stirred mixture is put into the extruder with the temperature of the main engine at 100-300°C for extrusion, the die surface is eagerly cut, pelletized, cooled, and packaged to make the desired moisture-removing coloring masterbatch.

Embodiment 3

[0015] Embodiment 3: prepare 100kg plastic moisture-removing coloring masterbatch

[0016] Take 36 kg of calcium oxide, 15 kg of benzidine yellow, 26 kg of paraffin, and 23 kg of high-density polyethylene resin for pre-mixing, then add it to a kneader with a rotation speed of 500-1800r / min and knead for 20 minutes, and knead until it is coated. Finally, put the evenly stirred mixture into an extruder with a host temperature of 100-300°C to extrude, heat-cut the die surface, pelletize, cool, and pack to make the desired moisture-removing coloring masterbatch.

Description

technical field [0001] The invention relates to the field of moisture-removing coloring of plastics. More specifically, the invention relates to a plastic moisture-removing coloring masterbatch and a preparation method thereof. Background technique [0002] At present, when domestic plastic product manufacturers use recycled plastics, in order to remove the moisture contained in recycled plastics, they use more polyolefin moisture-removing masterbatches. Although this product can achieve the purpose of dehumidification, because the product contains a large amount of calcium oxide, it will reduce the mechanical properties of the plastic product, and the side effects are great. At the same time, the plastic color masterbatch also contains a large amount of calcium carbonate, talcum powder, lithopone and other ingredients that will reduce the mechanical properties of the plastic. The simultaneous use of moisture-removing masterbatch and coloring masterbatch will double the ha...
