Abstract
The invention discloses a degradable environment-friendly plastic and a preparation method of the degradable environment-friendly plastic. The degradable environment-friendly plastic is formed by mixing and injection molding 45-60 % of PP (propene polymer), 3-8 % of POE (polyol ester), 15-35 % of starch, 5-15 % of calcium carbonate and 3-8 % of coupling agent. Compared with the prior art, the degradable environment-friendly plastic adopts starch to replace the existing petroleum, therefore, the resource can be saved, the environment-friendly performance can be improved; the degradable environment-friendly plastic has natural degrading period shorter than that of the exiting common plastic, and the product can be recycled; the waste plastic can be crushed to prepare new degradable environment-friendly plastic together with new raw material, and the purpose of protecting the environment and reducing the cost can be achieved.

Wherein, the recovery plastics are composed of the following components by weight percentage:
Preferably, above-mentioned starch-base complex is W-Gum or tapioca(flour) or both mixing.
Preferably, above-mentioned coupling agent is sec.-propyl three different stearoyl titanic acid ester or sec.-propyl three (dodecyl benzenesulfonyl) titanic acid ester or both mixing.
A kind of preparation method of degradable environmentally-friendly plastic, it may further comprise the steps:
1) each component is pressed formula ratio and drop into thorough mixing in the mixing roll;
2) mixed material drops into injection moulding in the injection moulding machine.
Preferably, during injection moulding, adopt screw injection molding machine; First section Heating temperature of screw rod is 155～175 ℃; Second section Heating temperature of screw rod is 175～195 ℃, and the 3rd section Heating temperature of screw rod is 200～220 ℃, and the Heating temperature of die head is 210～230 ℃.
Compared with prior art, the invention has the beneficial effects as follows:
1, replaces the oil of prior art with starch, can save resource, improve environmental-protecting performance;
2, be easy to degraded, product is compared with existing common plastics, and the natural degradation cycle shortens;
3, product can be recycled again, and the waste or used plastics of recovery can be processed new degradable environmentally-friendly plastic with new raw material after powder essence, not only environmental protection but also reduce cost.
