Problems solved by technology

[0002] At present, the feeding system for the production of injection molding products is to transport the mixed raw materials from the barrel to the hopper of the machine by the vacuum suction system. During the process of mixing and transporting, the distance between plastic particles and color masterbatch and the transporting plastic pipe Friction is generated between them, thereby forming static electricity. Since the specific gravity of the color masterbatch is lighter than that of the raw material, the color masterbatch is easily absorbed to the edge of the hopper, resulting in significantly less color masterbatch in the center of the hopper. When injection molding, the mixture in the center of the hopper enters the injection molding machine first. Screw, the color of the product produced will be lighter, and the mixture on the edge of the hopper (with more color masterbatch content) will finally enter the screw of the injection molding machine. Due to the large proportion of color masterbatch, the color of the product produced will be darker. If this continues, the color of the product will will always be unstable

Embodiment 1

[0029] This embodiment provides a kind of antistatic masterbatch, the raw material formula of this antistatic masterbatch is as follows:

[0030] Antistatic agent 2%, carrier resin 96%, auxiliary agent 2%, wherein, antistatic agent is aliphatic amine polyoxyethylene ether, purchased from Kunshan Shixin Plastic Co., Ltd., brand name is RMPA000175; carrier resin is polypropylene resin, purchased from From SABIC company, the brand is PP575; the auxiliary agent is vinyl bis stearamide, purchased from Changshu Huibang New Material Co., Ltd., the brand is RMPA000092.

[0031] The following preparation method is used to prepare the antistatic masterbatch. The preparation method is to mix the antistatic agent, carrier resin and additives uniformly, add them to the screw extruder, melt and knead and extrude at 160-230°C, and cool After granulation and drying, the antistatic masterbatch is obtained.

[0032] The antistatic masterbatch prepared by the above method has milky white appear...

Embodiment 2

[0035] Embodiment 2 (application of antistatic masterbatch in injection molding products)

[0036] The antistatic masterbatch of Example 1 is applied to the production of scissor handles.

[0037] The raw material formula of the scissors handle is 1kg of antistatic masterbatch, 1kg of color masterbatch, 15.5kg of polypropylene resin, and 7.5kg of calcium carbonate. The above raw materials are mixed and injection molded to make scissors handle. The above-mentioned medium color masterbatch is purchased from Kunshan Shixin Plastic Co., Ltd., the trademark is RMPA000805.

[0038] The results of scissors handles produced using the above raw materials are shown in Table 2.

[0039] Table 2 is the production situation of the handle of scissors of embodiment 2

[0040]

[0041] The above results show that the scissors handle produced by using the antistatic masterbatch of the present invention has no color difference in product color, stable quality, and a color difference ratio ...

Abstract

The invention relates to antistatic master batches and a preparation method and application thereof. The antistatic master batches are prepared from, by mass, 0.5-6% of an antistatic agent, 89-99% of carrier resin and 0.4-5% of auxiliaries, wherein the carrier resin is polypropylene resin, and the auxiliaries are a lubricant. The antistatic master batches have the good compatibility with resin, the good dispersibility and the good weather resistance. When the antistatic master batches are applied to the injection molding product processing industry, the problem that static electricity is generated due to friction of macromolecule materials is solved, the problem that color aberration is generated due to static electricity of the product is effectively solved, the product is stable in quality, meanwhile, the product has the certain antistatic effect, and the good dust removal effect on the surface of the product is achieved.
