Problems solved by technology
[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 environmentally harmless substances, which leads to the harm to the environment after traditional plastics are discarded

Embodiment Construction
[0019] Below in conjunction with specific example, do further explanation, the superfine filler material for plastics of the present invention is the mixture after the ultrafine pulverization of the raw material by following weight ratio: (weight unit KG, pulverization granularity is 1500 orders)
[0020] (1) Ordinary starch 15 corn flour 5 plant fiber 5
[0021] Calcium Carbonate 20 Talc 5 Bentonite 2
[0022] (2) Ordinary starch 25 corn flour 15 crop straw 15
[0023] Calcium Carbonate 30 Talc 10 Bentonite 5
[0024] (3) Ordinary starch 35 corn flour 25 plant fiber 25

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.
