Abstract
The invention discloses a degradable plastic, and relates to the technical field of degradable plastics. The degradable plastic comprises the following raw materials in parts by weight: 40 to 50 parts of PHB polymer, 30 to 40 parts of modified starch, 4 to 6 parts of PHV polymer, 6 to 8 parts of wood fiber powder, 3.5 to 5 parts of leather meal, and 2 to 4 parts of a coupling agent, wherein the modified starch adopts any one of modified corn starch, modified potato starch and modified cassava starch which are subjected to oxidation modification treatment. Compared with the prior art, the degradable plastic has good comprehensive performance and is easy to process, waste can be completely decomposed into low molecular compounds under the action of microorganism, and environment pollution is avoided.
Description
Technical field
The present invention relates to degradative plastics technical field, especially a kind of degradable plastics that can decompose completely under the effect of microorganism.
Background technology
Plastics are seen everywhere in our daily life, and the life for people provides greatly convenient, but waste plastic point to solve very slow in nature, decompose completely and want decades, even go up a century, cause environmental pollution, thus the degraded of plastics and re-using are urgent problems.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of degradable plastics, to solve the problem of plastic degradation difficulty.
In order to solve the problem, the technical solution used in the present invention is: this degradable plastics, is made up of the raw material of following weight part: 40 ~ 50 parts, PHB polymkeric substance, modified starch 30 ~ 40 parts, 4 ~ 6 parts, PHV polymkeric substance, wood fiber powder 6 ~ 8 parts, 3.5 ~ 5 parts, leather powder, coupling agent 2 ~ 4 parts.
In above-mentioned degradable plastics technical scheme, technical scheme can also be more specifically: described modified starch is any one in the modified corn starch of superoxidized modified process, modified potato starch, cassava modified starch.
Described PHB polymkeric substance, is by biosynthetic superpolymer, has the features such as nontoxic, plastic and easy degraded, and in active sludge, degraded needs some months, needs several years in seawater; Be applicable to the biological degradation carrier etc. manufacturing medical plastic magazine, mess-tin, agricultural film, long-acting pesticide, fertilizer.
Described modified starch is a kind of starch through modification, and namely ative starch is after process someway, changes its original physics or chemical property to some extent, add to can to make after in food formulations food process or edible time there is better properties.
Described PHV polymkeric substance, has many premium propertiess such as biodegradability, biocompatibility, by with PHB copolymerization, PHB can be improved because of high, the more crisp weakness of its degree of crystallinity, improve its mechanical property, in addition thermotolerance, water tolerance might as well.
A kind of high protein powder that described leather powder is before the leather tanning with various animal or tanned byproduct is made, main component is bone collagen albumen.
Described wood fiber powder, employing natural wood chip is raw material, and being that PU synthetic leather is special thickens Micropore Agent, can increase the thickness of coacervate and give feel and the elasticity of PU simulated leather, being widely used in motorway, coating, clothing leather, the industries such as plastics fabric.
Described coupling agent, in plastics are compounding, improves a kind of plastics additive of the interface performance of synthetic resins and inorganic filler or strongthener, also known as surface-modifying agent.It can reduce the viscosity of molten synthetic resin in plastic processes, improves the dispersity of weighting agent to improve processing characteristics, and then makes goods obtain good surface quality and machinery, heat and electrical property.
Degradable plastics of the present invention has good over-all properties, is easy to processing, can be used for preparation medical plastic magazine, mess-tin, agricultural film and various plastics; Its waste, under the effect of microorganism, can be decomposed into low molecular compound completely, avoid contaminate environment.
