Method for making disposable tableware by blending modified inorganic powder material and polypropylene

Abstract

A method for disposable tableware by blending modified inorganic powder material and polypropylene, including modifying inorganic powder material with modifier, blending them with polypropylene, and extrusion pelleting, injection molding or by extruding sheet, stamping or plastic uptake molding to get disposable tableware. Because the inorganic powder material modified before blending with polypropylene to produce disposable tableware, not only the quantity of the inorganic powder material increases largely, reduced the cost dramatically, but also the tableware meets the settled hygienic standard, to make such tableware to be of utility type and quite well competitive. The method provided is simple, reasonable, controllable, and the leftover bits and pieces of industrial material produced during the process can be reprocessed.

Description

1. Technical field [0001] The invention belongs to the technical field of preparing disposable tableware, and in particular relates to a method for preparing disposable tableware by blending modified inorganic powder materials and polypropylene. 2. Background technology [0002] With the improvement of people's living standards and food hygiene awareness, the demand for disposable tableware is increasing. However, the foamed tableware prepared with polystyrene as the main raw material is difficult to degrade and will cause serious pollution to the environment. In recent years, the relevant state departments have banned the manufacture and use of it. Then there are still problems of one kind or another in the disposable tableware that researches and develops and appears on the market. Although the tableware prepared by pulp will not pollute the environment, its strength is low and the price is higher, which affects other products. The sales volume on the market, especially t...

AI Technical Summary

Problems solved by technology

Although this tableware solves the problems of price and degradation rate to a certain extent, it is still unsatisfactory. The reason is that the amount of calcium carbonate added is small, and the general amount can only be below 20%, otherwise it will not reach Therefore, the production cost is still high and cannot be compared with the price of polystyrene foam lunch boxes, which has affected its promotion and application to a certain extent.
