Embodiment 1

[0047] A wear-resistant plastic bag is composed of the following raw materials in parts by weight: 100 parts of polybutylene succinate and 3 parts of wear-resistant masterbatch; wherein, the wear-resistant masterbatch is calculated by weight percentage and includes the following components: polybutylene succinate Tetrafluoroethylene 0.5%, composite anti-wear agent 12%, nano-titanium dioxide 0.2%, stearic acid 0.25%, polyphenylene ether ketone 0.5%, polydimethylsiloxane 0.3%, octadecyldiethanolamine 0.38%, 4.2% of talcum powder, 0.6% of 2,6-di-tert-butyl-4-methylphenol, 0.36% of coupling agent, 0.52% of plasticizer, and the balance is polybutylene succinate chips.

[0048] The preparation method of composite anti-wear agent comprises the following steps:

[0049] One, the preparation of porous calcium carbonate;

[0050] Weigh an appropriate amount of Na with a particle size of 50 μm 2 CO 3 solid, and transfer it to a suction filtration device, and then slowly add an appropr...

Embodiment 2

[0068] The preparation process of the wear-resistant plastic bag is similar to that of Example 1, except that the ratio of the raw materials used is different; specifically: 110 parts of polybutylene succinate and 10 parts of wear-resistant masterbatch;

[0069] Among them, the wear-resistant masterbatch includes the following components by weight percentage: 0.6% polytetrafluoroethylene, 16% composite wear-resistant agent, 0.3% nano-titanium dioxide, 0.28% stearic acid, 0.55% polyphenylene ether ketone, 0.32% methyl siloxane, 0.45% octadecyldiethanolamine, 4.5% talc, 0.68% 2,6-di-tert-butyl-4-methylphenol, 0.42% coupling agent, 0.56% plasticizer , and the balance is polybutylene succinate chips.

Embodiment 3

[0071] The preparation process of the wear-resistant plastic bag is similar to that of Example 1, except that the ratio of the raw materials used is different; specifically: 120 parts of polybutylene succinate and 18 parts of wear-resistant masterbatch;

[0072] Among them, the wear-resistant masterbatch includes the following components by weight percentage: 0.8% polytetrafluoroethylene, 20% composite wear-resistant agent, 0.4% nano-titanium dioxide, 0.32% stearic acid, 0.6% polyphenylene ether ketone, 0.36% methyl siloxane, 0.52% octadecyldiethanolamine, 5.0% talc, 0.75% 2,6-di-tert-butyl-4-methylphenol, 0.55% coupling agent, 0.6% plasticizer , and the balance is polybutylene succinate chips;

Abstract

The invention relates to the technical field of plastic bag preparation, in particular to a wear-resistant plastic bag and a preparation method thereof. The material is prepared from the following raw materials in parts by weight: 100-120 parts of poly (butylene succinate) and 3-18 parts of wear-resistant master batch, wherein the wear-resistant master batch is prepared from the following components in percentage by weight: 0.5 to 0.8 percent of polytetrafluoroethylene, 12 to 20 percent of a composite wear-resistant agent, 0.2 to 0.4 percent of nano titanium dioxide, 0.25 to 0.32 percent of stearic acid, 0.5 to 0.6 percent of polyphenyl ether ketone, 0.3 to 0.36 percent of polydimethylsiloxane, 0.38 to 0.52 percent of octadecyl diethanolamine, 4.2 to 5.0 percent of talcum powder, 0.6 to 0.75 percent of 2, 6-di-tert-butyl-4-methylphenol, 0.36 to 0.55 percent of a coupling agent, 0.52 to 0.6 percent of a plasticizer and the balance of poly butylene succinate slices. The prepared plastic bag not only has good wear resistance, but also has a certain slow-release antibacterial effect, and the service life of the plastic bag is prolonged while the wear resistance of the prepared plastic bag is effectively improved.

Description

technical field [0001] The invention relates to the technical field of plastic bag preparation, in particular to a wear-resistant plastic bag and a preparation method thereof. Background technique [0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily life and are often used to hold other items. It is widely used because of its cheap, extremely light weight, large capacity, and easy storage. [0003] A high-temperature-resistant plastic bag and its preparation method are disclosed in the patent document with the application number CN201810641423.X, wherein the preparation method includes: polyvinyl chloride, modified carbon fiber, polyethylene terephthalate , ethylene oxide, fillers, plasticizers and antioxidants are mixed and granulated and then extruded to obtain high-temperature resistant plastic bags, which solves the problem that ordinary plastic bags have poor high-temperature resistance and are often us...
