Wear-resistant hollow plate and production method thereof

Abstract

The invention discloses a wear-resistant hollow plate and a production method thereof. The wear-resistant hollow plate is made from the following components according to parts by weight: 18-38 parts of polycaprolactone, 18-32 parts of polyethylene, 9-22 parts of polypropylene, 8-17 parts of acrylic resin, 18-34 parts of dialdehyde starch, 7-23 parts of silicon dioxide, 9-24 parts of glass fiber, 9-21 parts of glycerol, 7-18 parts of sodium chloride, 3-11 parts of sodium hydroxide, 7-25 parts of silicon dioxide, and 19-39 parts of water. The hollow plate produced herein is good in wear resistance and is waterproof, damp-proof and oil-proof; the production method described herein has simple process and low cost.

Description

technical field

[0001] The invention belongs to the field of packaging materials, and relates to a hollow plate packaging material, in particular to a wear-resistant hollow plate and a preparation method thereof. Background technique

[0002] Currently, there are many kinds of packaging materials used in packaging products made of glass, steel, metal and aluminum materials, and the packaging materials can be used during transportation, preservation and storage until delivered to users. During transportation and storage, products are exposed to many external factors, these are moisture, humidity, oil, dust and impacts. Therefore, in order to protect products from being damaged by these external factors, highly resistant packaging materials are required.

[0003] Because glass, steel, metal and aluminum are hard and heavy, they can be difficult to pack. The materials used to package these products should be resistant to water, moisture or oil, scratches and dust, and not to ...
