Abstract
The invention discloses an anti-static biodegradable plastic. The anti-static biodegradable plastic is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of corn starch, 10-15 parts of peanut meal, 10-15 parts of peanut shell powder, 3-5 parts of mica powder, 0.5-1 part of coco fatty acid diethanol amide, 0.1-0.2 part of polyglycerol polyricinoleate, 1-2 parts of pentaerythritol stearate, 10-15 parts of acetyl tributyl citrate, 0.5-1 part of calcium stearate, 1-2 parts of erucyl amide and 10-15 parts of polypropylene. The biodegradable plastic disclosed by the invention has good biodegradability, good thermal stability and good anti-static property, has certain water resistance, and relatively good abrasive resistance and corrosion resistance, and is good in usability, low in cost, easily available in raw material, simple and feasible in preparation technology, safe, nontoxic and suitable for occasions with special anti-static requirements; and the use safety coefficient of the material is effectively improved.
Description
Technical field
The present invention relates to plastics arts, be specifically related to a kind of anti-electrostatic biodegradable plastic and preparation method thereof.
Background technology
At present, plastics have been widely applied to all respects that people produce, live.Along with the production of plastics and developing rapidly of application, plastics increase and consumption constantly increases.These plastics overwhelming majority is disposable product, and waste plastic is extremely difficult, residual becomes white garbage in the environment, has threatened the balance of ecotope and the mankind, vegeto-animal existence.Meanwhile, because plastics industry is based on oil, and oil and natural gas resource is difficult to meet the growing demand in the whole world, shortage occurs.For plastics pollution, save energy and resource, solve the problems such as raw material sources is not enough, and bio-degradable plastics obtains more concern and development.
Biodegradable plastic can be decomposed by environmental microorganism after referring to and discarding, and is finally degraded into the macromolecular material of the inorganics such as water and carbonic acid gas.Because it does not remain in the environment, can play the effect of good protection of the environment, its application prospect is very wide.In actual use, biodegradable plastic not only needs good degradation property, also should possess excellent use properties and rational cost, is convenient to promote and use.
Summary of the invention
The object of this invention is to provide a kind of anti-electrostatic biodegradable plastic, with low cost, make simple, safety non-toxic, degradation property and use properties good.
The present invention is achieved by the following technical solutions:
A kind of anti-electrostatic biodegradable plastic, it is obtained by the raw material of following weight parts:
W-Gum 20-30, peanut meal 10-15, peanut hull meal 5-10, mica powder 3-5, lauric acid amide of ethanol 0.5-1, polyglycerol polyricinoleate 0.1-0.2, pentaerythritol stearate 1-2, tributyl acetylcitrate 10-15, calcium stearate 0.5-1, erucicamide 1-2, polypropylene 10-15;
A preparation method for anti-electrostatic biodegradable plastic, it comprises the following steps:
(1) by mica powder 200-300 DEG C of process 3-6h, add W-Gum, peanut meal and peanut hull meal after cooling, co-ground is even, crosses 300-400 mesh sieve, obtains mixed powder;
(2) mixed powder obtained in (1) is added in dehydrated alcohol by solid-liquid weight ratio 1:3-1:4, first ultrasonic disperse 10-15min, then add lauric acid amide of ethanol and pentaerythritol stearate, reflux process 3-5h, the desolventizing of cooling final vacuum extrct, obtains mixture;
(3) first by the mixture that obtains in (2) and tributyl acetylcitrate common high-speed mixing 10-20min under 80-100 DEG C of condition, add polyglycerol polyricinoleate, calcium stearate, erucicamide and polypropylene high-speed mixing 15-30min under 120-140 DEG C of condition again, obtain mixed resin;
(4) mixed resin obtained in (3) is added twin screw extruder, control temperature is extruded in 150-180 DEG C, after cooling granulation and get final product.
Wherein, lauric acid amide of ethanol and pentaerythritol stearate is utilized to carry out modification to the stopping composition that W-Gum, pumpkin powder, maize straw, ground barium sulfate etc. are main raw material, the dispersiveness of reinforcing filler, strengthens raw-material consistency, intensified waterproof performance; Pentaerythritol stearate, polyglycerol polyricinoleate, erucicamide improve the antistatic performance of material by synergy; Calcium stearate, erucicamide can play collaborative lubrication, auxiliary plastification.
Advantage of the present invention is:
1. by the improvement of recipe optimization, the biodegradable plastic obtained is made to have good biodegradability properties energy, Heat stability is good, antistatic performance is good, and there is certain water tolerance and wear-resisting, erosion resistance preferably, effectively improve the use safety coefficient of material, use properties is good, is applicable to the occasion of anti-electrostatic particular requirement;
2. the main raw material adopted is with low cost, and raw material is easy to get, and manufacture craft is simple, safety non-toxic, meets the requirement of environmental protection and energy saving.
