High-strength low-temperature resistant material for turnover box

Abstract

The invention discloses a high-strength low-temperature resistant material for a turnover box, The high-strength low-temperature resistant material is prepared from the following components in parts by weight: 89 to 137 parts of polypropylene, 57 to 84 parts of high-density polyethylene, 17 to 33 parts of SEBS, 3 to 11 parts of alumina, 5 to 13 parts of aluminum-doped zinc oxide whisker, 4 to 17 parts of hollow glass microspheres, 5 to 19 parts of nano attapulgite, 5 to 13 parts of organic modified montmorillonite, 4 to 16 parts of wollastonite powder, 0.1 to 2 parts of an antioxidant, 0.5 to3 parts of a compatibilizer, 0.1 to 4 parts of naphthenic oil, and 0.1 to 3 parts of EBS; the raw materials are subjected to the steps of mixing, extruding, water cooling, pulling for strip forming, pelletizing and the like. The high-strength low-temperature resistant material disclosed by the invention has high mechanical strength and excellent anti-aging performance and antistatic performance, can meet the application requirements of the turnover box under low temperature use conditions, has high impact strength, and is resistant to throw and impact, and the material disclosed by the invention can be widely used in low temperature climate outdoor turnover boxes and other fields.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-strength low-temperature-resistant material for a turnover box. Background technique [0002] With the development of the transportation industry and the container industry, convenient and safe transportation can ensure the quality of transportation and reduce transportation costs, which makes turnover boxes play an important role in the entire transportation process. Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are resistant to acid, alkali, oil, non-toxic and tasteless. They can be used to hold machinery, home appliances, fruits and vegetables, etc. . At the same time, the turnover box can be matched with a variety of logistics containers and workstations, used in various warehouses, production sites and other occasions, and is a mus...

AI Technical Summary

Problems solved by technology

In the low temperature environment, the polymer chains in the material cannot effectively transmit / diffuse the internal stress and external destructive force due to the restricted movement, so the cracking of the part is more likely to occur.

[0004] However, the functions of these turnover boxes are still single, and the above deficiencies cannot be solved at the same time.
