Abstract

The invention discloses a UV degradable stone-plastic material and a preparation method thereof. The UV degradable stone-plastic material is prepared from the following components in parts by mass: 50-60 parts of limestone powder, 15-20 parts of co-polypropylene, 10-15 parts of homo-polypropylene and 1-5 parts of a modifier. The UV degradable stone-plastic material provided by the invention can bephotolyzed, does not cause environmental pollution, is relatively low in production cost, has relatively high compressive strength, edge pressure strength and impact strength, and can be used for transportation and packaging.

Description

Technical field[0001]The invention relates to the field of transportation packaging, in particular to a UV degradable stone plastic material and a preparation method thereof.Background technique[0002]In daily life, people use a large number of cartons to place, transfer and store items. In particular, corrugated paper is more widely used due to its stable mechanical structure and cushioning properties. However, carton packaging has the following disadvantages: (1) It is easy to collapse and deform after being exposed to water and damp; (2) Cargo damage is caused by rat bites; (3) It consumes wood materials, and it consumes 2.56 cubic meters of wood to produce 1 ton of corrugated paper. 100 cubic meters of water; (4) Another source of domestic corrugated paper production is imported waste paper. However, with the recent tightening of foreign waste quotas, there is a shortage of raw materials, and the price of carton packaging continues to rise.[0003]Therefore, it is a technical probl...
