Description
Technical field
The present invention relates to plastics arts, be specifically related to a kind of antimildew and antibacterial biodegradable plastic and preparation method thereof.
Background technology
At present, plastics have been widely applied to the various aspects that people produce, live.Along with the production of plastic and developing rapidly of application, plastics increase and consumption figure is continuously increased.These plastics overwhelming majority is disposable product, and the extremely difficult process of waste plastic, and residual becomes white garbage in the environment, has threatened balance and the mankind, the vegeto-animal existence of ecological environment.Simultaneously as plastics industry is based on oil, and oil and natural gas resource is difficult to meet the demand that the whole world is growing, has occurred and that shortage.For plastics pollution, saving the energy and resource, solve the problems such as raw material sources is not enough, biodegradable plastics has obtained more concern and development.
Biodegradable plastic can be decomposed by environmental microorganism after referring to discard, and is finally degraded into the macromolecular material of the inorganic matter such as water and carbon dioxide.Owing to it remains the most in the environment, can play the effect well protecting environment, its application prospect is the most wide.In actual use, biodegradable plastic not only needs good degradation property, also should possess excellent serviceability and rational cost, it is simple to promote and use.
Summary of the invention
The present invention is to provide a kind of antimildew and antibacterial biodegradable plastic, have with low cost, make simple, the feature of safety non-toxic, and degradability and serviceability good.
One antimildew and antibacterial biodegradable plastic of the present invention, it is to be prepared by the raw material of following weight parts:
Potato starch 20-30 part, Cortex Cinnamomi powder 3-5 part, potato haulm 10-15 part, medical stone powder 3-5 part, tannic acid 0.5-1 part, boric acid 0.5-1 part, glycerol monolaurate 1-2 part, stearic acid 3-5 part, oleamide 1-2 from, tributyl 2-acetylcitrate 10-15 part, propyl p-hydroxybenzoate 0.01-0.02 part, polypropylene 10-15 part.
The preparation method of the present invention a kind of antimildew and antibacterial biodegradable plastic, it comprises the following steps:
(1) after being mixed with potato haulm by medical stone powder, 100-150 DEG C processes 3-6h, adds potato starch and Cortex Cinnamomi powder after cooling, and co-ground is uniform, 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, add tannic acid, boric acid, glycerol monolaurate, stearic acid and propyl p-hydroxybenzoate, it is heated to reflux processing 3-5h, cooling final vacuum extracting removes solvent, obtains mixed material；
(3) first by the mixed material obtained in (2) and tributyl 2-acetylcitrate common mixed at high speed 10-20min under the conditions of 80-100 DEG C, add oleamide and polypropylene mixed at high speed 15-30min under the conditions of 120-140 DEG C, obtain mixed resin；
(4) mixed resin that obtain in (3) is added double screw extruder, control temperature in 150-180 DEG C of extrusion, after cooling granulation and get final product.
Wherein, utilize tannic acid, boric acid, glycerol monolaurate and stearic acid that the inserts that potato starch, Cortex Cinnamomi powder, potato haulm, medical stone powder are raw material is modified, the dispersibility of reinforcing filler, strengthen the raw-material compatibility, water resistance；In raw material, glycerol monolaurate, propyl p-hydroxybenzoate and Cortex Cinnamomi powder have the synergism of antibacterial and mouldproof, and oleamide can improve greasy property, play collaborative lubrication.
The invention have the advantage that
1, by the improvement of formula Yu technique, making the biodegradable plastic prepared have good antimildew and antibacterial performance and biodegradable properties, Heat stability is good, and have certain resistance to water, serviceability is good；
2, the primary raw material used is with low cost, and raw material is easy to get, and processing technology is simple, safety non-toxic, meets the requirement of environmental protection and energy saving.
Detailed description of the invention
Below in conjunction with specific embodiment, one antimildew and antibacterial biodegradable plastic of the present invention and preparation method thereof is described further.
