Problems solved by technology

Although the product made by this method can play an anti-aging effect, it increases the mixing time in production and the equipment cleaning time and the waste of raw materials when cleaning the equipment, and it will cause the products in production due to uneven dispersion or waste of air bubbles
And the labor cost is high and the efficiency is low

Embodiment 1

[0018] Polypropylene 99%

[0019] Zinc Oxide 0.1%

[0020] Antioxidant 0.4%

[0021] UV absorber 0.3%

[0022] Deoxidizer 0.2%

[0023] Mixing: Put the above-prepared raw materials on the teller mixer and mix them evenly before discharging.

[0024] Granulation: Put the above mixed raw materials into the granulator for granulation. The resulting particles are the finished masterbatch. The granulator can be a twin-screw extrusion granulator or a single-screw extrusion granulator.

Abstract

The invention relates to an aging-resistant plastic masterbatch. The aging-resistant plastic masterbatch comprises the following components by weight percentage: 95-99% of polyolefin resin, 0.05-0.12% of a light stabilizing agent, 0.2-1% of an anti-oxidant, 0.1-0.9% of an ultraviolet ray absorber, and 0.2-1% of a deoxidizer. Compared with the prior art, the aging-resistant plastic masterbatch has impact and aging-resistance performances, and reduces the raw materials waste due to equipment cleaning during a usage process.

Description

technical field [0001] The invention relates to the field of plastic master batches, in particular to an anti-aging plastic master batch. Background technique [0002] Since plastic products are manufactured by copolymerization and mixing under high temperature conditions during production and processing, the surface of the produced products will age and absorb dust in the air, resulting in dust pollution of plastic products. [0003] At present, the anti-aging method widely used in the plastic industry is to directly use anti-aging agent and polyolefin resin to mix according to a certain ratio, and process it into plastic products. Although the product made by this method can play an anti-aging effect, it increases the mixing time in production and the equipment cleaning time and the waste of raw materials when cleaning the equipment, and it will cause the products in production due to uneven dispersion or Air bubbles cause waste. And artificial production cost is high, a...
