Problems solved by technology

Documents CN2012100766897 and CN2012100766666 disclose a processing method for polymer trays. The trays produced by this method are molded under high temperature and high pressure. The surface of the tray is rough and the structural performance is poor. , poor toughness can not be used for long-term turnover, and cannot be used on warehouse shelves
[0005] How to prepare a plastic pallet with large load, high strength, strong impact resistance and corrosion resistance is a technical problem to be solved urgently in the prior art

Embodiment 1

[0026] Take the production of pallets with a length, width and height of 1200mm×1000mm×155mm as an example:

[0027] A built-in steel pipe tray, which is prepared according to the following method:

[0028] 1. Material preparation:

[0029] Material A: mix polyethylene and polypropylene according to the mass ratio of 4:6, then put it into the shredder, and control the particle size below 10mm;

[0030] Material B: Dioctyl sebacate, butyl ethyl oleate, chlorinated propylene resin and polyolefin elastomer (POE) are mixed according to the mass ratio of 10:8:5:3;

[0031] Material C: Mix borax, calcium carbonate, talc powder and mica powder according to the mass ratio of 2:1:1:1, and control the particle size below 100um.

[0032] Material D: Steel pipe with a diameter of 10mm and the same length as the four sides of the bottom of the tray.

[0033] 2. Preparation method:

[0034] Mix material A, material B and material C according to the mass ratio of 10:2:1, and put them int...

Embodiment 2

[0036] The preparation method is the same as in Example 1, except that no steel pipe is added.

Embodiment 3

Abstract

The invention discloses a pallet with built-in steel tubes. The pallet is manufactured from polyethylene, polypropylene, dioctyl sebacate, butyl and ethyl oleate, propylene chloride resin, polyolefin elastomers, borax, calcium carbonate, talcum powder and mica powder proportionally. The method further discloses a method for manufacturing the plastic pallet with the built-in steel tubes. The pallet manufactured by the method is high in load, strength and impact resistance, is corrosion-resistant and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of plastic processing, and in particular relates to a plastic tray with a built-in steel pipe and a preparation method thereof Background technique [0002] As my country's extensive bulk storage and transportation methods are gradually changing to centralized full-box intensive methods, plastic pallets are in a period of rapid growth in my country and are widely used in warehousing and transportation industries. At present, about 80 million pallets are needed for domestic circulation each year, of which 20 million are used by ports (for export), and the total demand will further increase. Although plastic pallets came into the market late in China and the cost is relatively high, they are still growing at a rate of more than 10% every year. In addition, the share of plastic pallets in developed countries is about 40% of the total, while the future plastic pallets in my country is only about 15%, which indicates that...
