Abstract

The invention relates to a method to make compounding biodegradation material. It is made up of poly-caprolactone, poly-lactic acid and polyethylene glycol after taking the process of whisking twin-screw extruding. It is a degrading material that has no pollution to the environment and could be used in medical, agriculture and consumer goods package fields.

Description

The preparation method of composite biodegradable material
Technical field
The present invention relates to the preparation method of composite biodegradable material.
Background technology
Along with rapid development of economy, non-returnable container goods, medical treatment product, industrial or agricultural film etc., the widespread use in industrial or agricultural, daily life causes white pollution to become the social effects of pollution of human survival and development.Particularly mass production and use nondegradable material not only causes the huge waste of resource, and serious pollution of ecological environment.Light, biodegradable material that prior art is produced, mostly be with polypropylene, polyethylene add starch or lime carbonate or talcum powder, olefin lubricant makes, but this technology belongs to disintegration-type, is not complete biodegradable.
Summary of the invention
The purpose of this invention is to provide a kind of pollution-free, the preparation method of composite biodegradable material completely degrades.
The object of the present invention is achieved like this; The preparation method is as follows:
(1), the polycaprolactone 20-95 part of getting ratio of weight and number, poly(lactic acid) 25-100 part, polyoxyethylene glycol 1-5 part;
(2), the raw material of above-mentioned ratio of weight and number added stirs in the mixing roll, when stirring material temperature to 40 ℃-55 ℃, become premix, premix is added tie rod pelletizing packing in the parallel dual-screw extruding granulator, make composite biodegradable material.
The technical progress that the present invention obtains is: the microbiological deterioration material is a poly(lactic acid) in the component of the present invention, is to be polymerized by corn fermentation, but mechanical property is crisp, poor toughness.The biodegradable material of synthetic is a polycaprolactone in the component of the present invention, and fusing point is low, but tensile strength toughness is big, and is the unique material that can be degraded by water.The present invention not only makes two kinds of organic compound blend of biodegradable material, and can make mixture performance function to greatest extent, change original component character, well can regulate and control material character on request, can effectively improve Mechanical Properties of Materials by compound blend.The more important thing is biodegradable material after compound can be in soil, water pool or under the anaerobic condition complete biodegradable, can also recycle simultaneously, can not cause environmental pollution.The present invention adopts the mixing reaction of parallel dual-screw to extrude tie rod pelletizing packaging disposable and finishes.
Embodiment
Embodiment one:
(1) gets 20 kilograms of poly(lactic acid), 25 kilograms of polycaprolactones, 1 kilogram of polyoxyethylene glycol
(2) material of said ratio is added stir in the mixing roll, during whipping temp to 40 ℃-55 ℃, become premix, premix is added tie rod pelletizing packing in the parallel dual-screw extruding granulator, make composite biodegradable material.Composite biodegradable material is mainly used in fields such as medicine, agricultural and consumer package.
Embodiment two:
(1) gets 47.5 kilograms of poly(lactic acid), 50 kilograms of polycaprolactones, 2.5 kilograms of polyoxyethylene glycol
(2) material of said ratio is added stir in the mixing roll, during whipping temp to 40 ℃-55 ℃, become premix, premix is added tie rod pelletizing packing in the parallel dual-screw extruding granulator, make composite biodegradable material.Composite biodegradable material is mainly used in fields such as medicine, agricultural and consumer package.
Embodiment three:
(1) gets 95 kilograms of poly(lactic acid), polycaprolactone double centner, 5 kilograms of polyoxyethylene glycol
(2) material of said ratio is added stir in the mixing roll, during whipping temp to 40 ℃-55 ℃, become premix, premix is added tie rod pelletizing packing in the parallel dual-screw extruding granulator, make composite biodegradable material.Composite biodegradable material is mainly used in fields such as medicine, agricultural and consumer package.

Claims (1)

1, the preparation method of composite biodegradable material is characterized in that: preparation method's step is as follows:
(1), the polycaprolactone 50-95 part of getting ratio of weight and number, poly(lactic acid) 25-100 part, polyoxyethylene glycol 1-5 part;
(2), the raw material of above-mentioned ratio of weight and number added stirs in the mixing roll, when stirring material temperature to 40 ℃-55 ℃, become premix, premix is added tie rod pelletizing packing in the parallel dual-screw extruding granulator, make composite biodegradable material.
