Transparent wear-resisting plastic alloy and preparation method thereof

Abstract

The invention discloses a transparent wear-resisting plastic alloy and a preparation method of the plastic alloy. The plastic alloy comprises the components as follows: 65-95% of polylactic acid with the viscosity average molecular weigh between 90,000-250,000, 5-35% of polyoxymethylene with the viscosity average molecular weigh between 2-10, 0.1-1% of a transparent reagent and 0-2% of a plasticizer. The preparation method comprises the following steps: firstly, putting polylactic acid and polyoxymethylene which are measured and dried into a mixer, and adding the plasticizer and mixing uniformly at room temperature, so as to wet the materials fully and uniformly; secondly, mixing uniformly the transparent reagent and the fully-wetted materials at room temperature; thirdly, mixing uniformly an assistant and the fully-wetted materials at room temperature; and fourthly, putting the mixed materials into a double screw extruder, performing mixing, plasticization and extrusion on the materials fully and uniformly, and then pelleting by a pelletizer.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to a plastic alloy with transparent wear resistance and a preparation method thereof. Background technique [0002] Plastic alloys are a class of new materials with high performance, functionalization and specialization obtained by physical blending or chemical grafting. Plastic alloy products can be widely used in automobiles, electronics, precision instruments, office equipment, packaging materials, building materials and other fields. It can improve or increase the performance of existing plastics and reduce costs, and has become one of the most active varieties in the plastics industry, growing very rapidly. [0003] Traditional plastic alloy materials include PLA / ABS, PLA / PBS, PLA / PC, PLA / ABS, PLA / PPC, PLA / PHA, PLA / PMMA, PLA / PCL and so on. However, the performance of existing plastic alloys is relatively single. If the mechanical stress performance is satisfied, it may not necessarily have ...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a transparent and wear-resistant plastic alloy and its preparation method. The technical problem to be solved is that the existing plastic alloy has relatively single properties, and it is impossible to make the material transparent while having wear-resistant properties.
