Problems solved by technology

However, plastic film products are prone to oxidative decomposition when processed in the presence of oxygen, which damages the mechanical properties and electrical properties of the plastic, discolors them, and affects the service life and appearance of plastic products due to oxidation or ultraviolet rays during use.
If additives are forcibly added, the content of additives in the masterbatch is too high, the carrier will be reduced, the granulation effect of the masterbatch will be poor, the particle size will be different, and the phenomenon of "slag dropping" will occur if there is a slight collision during transportation, which will cause greater harm. The reason is that the dispersion of additives is poor and the synergistic effect is not obvious, resulting in poor quality of masterbatch and ultimately affecting the quality of plastic products

Embodiment 1

[0016] A masterbatch for plastic film products, its composition and corresponding weight percentage are as follows:

[0017]

[0018] The described manufacture method of the masterbatch that is used for plastic film product, comprises the following steps:

[0019] a. Weighing: Carrier powder PE8250, light stabilizer UV944, light stabilizer UV770, antioxidant 1010, zinc stearate SAK-ZS-PLB are weighed according to the proportion.

[0020] b. Stirring: Put the carrier and additives into the high mixer and stir in turn. The amount of the mixed material should not exceed 2 / 3 of the volume, the speed is 10-20Hz, and the mixing time is 15 minutes.

[0021] c. Pelletizing: put the compounded mixture into the extruder, and cut the pellets through the pelletizer after the material is discharged from the die.

[0022] d. Screening: The cut particles are passed through a vibrating sieve, and the masterbatch with uniform size is screened out for packaging.

Abstract

The invention relates to master batch for plastic film products and a manufacturing method of the master batch. The master batch for the plastic film products comprises components as follows: 76%-82.5% of Sinopec MaomingPE8250, 6%-8% of a BASF light stabilizer UV944, 6%-8% of a BASF light stabilizer UV770, 5%-7% of a BASF antioxidant 1010 and 0.5%-1% of zinc stearate SAK-ZS-PLB. The master batch is prepared by the steps of weighing, stirring, pelletizing and screening. A polyphenol antioxidant 1010 is reasonably added, accordingly, the purpose of antioxidation of the plastic film products is realized; the added light stabilizers are organic amine oxidants with a stereo-hindrance effect, and can convert light energy into heat energy by means of molecular structures of the light stabilizers, therefore, plastic materials can be prevented from having an oxidation reaction, and the weather resistance level of the plastic products is improved; the three auxiliaries perform a synergistic effect, so that the application effect of the auxiliaries is further improved.

Description

technical field [0001] The invention relates to the technical field of plastic master batches, in particular to a master batch for plastic film products and a manufacturing method thereof. Background technique [0002] The use of plastic film for packaging and as a coating layer has been widely used in various fields, which has brought great convenience to people. However, plastic film products are prone to oxidative decomposition when processed in the presence of oxygen, which damages the mechanical and electrical properties of the plastic and discolors it. Moreover, the service life and appearance of the plastic product will be affected by oxidation or ultraviolet rays during use. If additives are forcibly added, the content of additives in the masterbatch is too high, the carrier will be reduced, the granulation effect of the masterbatch will be poor, the particle size will be different, and the phenomenon of "slag dropping" will occur if there is a slight collision durin...
