Superfine stuffing for plastic and its application

Abstract

The superfine stuffing capable of making plastic degradable and good in machining performance is superfine crushed mixture of starch, corn powder, plant fiber, calcium carbonate, talcum powder and bentonite. The stuffing makes plastic possess certain flowability and lubricity for easy machining and makes plastic become microbe degradable and beneficial to plant and harmless to natural environment.

Description

Technical field: [0001] The invention relates to a filling material for polymer synthetic materials, in particular to an ultrafine filling material for plastics, and also relates to the application of the ultrafine filling material in plastics. technical background: [0002] Existing plastic filling materials are mixed with inorganic materials such as calcium carbonate, talcum powder, and bentonite. Because they do not contain organic substances that can be decomposed and utilized by microorganisms, plastic products added with such fillers are difficult to be processed under natural conditions. Microorganisms decompose and transform into substances that are harmless to the environment, thus causing harm to the environment after traditional plastics are discarded. On the other hand, my country has abundant starch (such as corn starch, potato starch, etc.), and corn and crop stalk resources are urgently waiting for deep processing and utilization.
