Abstract
The invention discloses a degradable modified plastic with the good low temperature resistance. The degradable modified plastic is prepared from, by weight, 20-40 parts of polyhydroxyalkanoate, 30-50 parts of epoxy resin, 2-8 parts of modified starch, 3-6 parts of nanometer tin antimony oxide, 2-6 parts of ethyl cellulose, 2-6 parts of phthalic anhydride, 1-2 parts of butyl stearate, 3-7 parts of an ethylene-vinyl acetate copolymer, 2-10 parts of nano-silicon dioxide, 5-8 parts of a silane coupling agent, 0.1-0.5 part of an antioxidant 1076 and 1-2 parts of phosphite ester. The degradable modified plastic is simple in preparation method, does not need special instruments, is low in cost and friendly to environment and has the advantages of being degradable, long in service life, good in low temperature resistance, high in elastic strength and the like; when plastic film prepared from the degradable modified plastic through deep processing is applied to vegetable or flower greenhouses, the advantages that the low temperature resistance is good, the thermal insulation effect is obvious, and waste products can be automatically degraded are achieved.
Description
Technical field
The present invention relates to plastics technical field of improvement and in particular to a kind of good modified plastics of lower temperature resistance of degradable and
Its manufacture method.
Background technology
In recent years, with the generation of high molecular polymer-polrvinyl chloride, polyethylene, plastic sheeting is widely used in agriculture
Industry；Again because hot house can utilize solar energy, and there is certain insulation effect；Simultaneously because can be using light skeleton material
Material, easily builds and appearance, can take lattice on the spot, construction investment is less, and economic benefit is higher；And natural disaster can be resisted, cold-proof
The effect such as insulation, widely uses in agriculture, woods, animal husbandry, thus deep welcome by Producer.With the development of plastics industry,
Commonly used by countries in the world.Modified plastics refers to, on the basis of general-purpose plastics and engineering plastics, through filling, blending, increase
The method processing such as strong, improves the plastic of the performance of the aspects such as anti-flammability, intensity, impact resistance, toughness.Modified plastics blows
The thin film made is widely used in booth.But it is as increasing of usage amount, inevitably environment is caused with white dirt
Dye.
Content of the invention
1st purpose of the present invention is the modified plastics providing a kind of lower temperature resistance of degradable good.
2nd purpose of the present invention is the manufacture method of the good modified plastics of lower temperature resistance of above-mentioned degradable.
To achieve these goals, the invention provides a kind of good modified plastics of lower temperature resistance of degradable, by as follows
The material composition of weight portion:
PHA 20-40, epoxy resin 30-50, modified starch 2-8, nano antimony tin oxide 3-6, ethyl cellulose
Plain 2-6, phthalic anhydride 2-6, butyl stearate 1-2, ethylene-vinyl acetate copolymer eva 3-7, nano silicon 2-
10th, silane coupler 5-8, antioxidant 1076 0.1-0.5, phosphite ester 1-2.
A kind of manufacture method of the good modified plastics of lower temperature resistance of degradable, comprises the following steps:
Step one: nano antimony tin oxide is placed in the ultrasonic cleaning instrument of 30-50khz, using the ultrasonic 20- of dehydrated alcohol
50min；Ultrasonic finish after, with absolute ethanol washing 2-3 time, 60-90 DEG C of drying is to constant weight, stand-by；
Step 2: according to formula by PHA, epoxy resin, ethyl cellulose, modified starch, phthalic acid
Acid anhydride, nano silicon, ethylene-vinyl acetate copolymer eva, butyl stearate, silane coupler, antioxidant 1076, Asia
Nano antimony tin oxide in phosphate ester and step one mixes 20-30min in high-speed mixer；Twin-screw extrusion is poured into after taking-up
In machine, melt blending, extruding pelletization.
Furtherd investigate and modified in the enterprising step of the original technical support of our company, retained the excellent of former improvement plastics
Gesture, adds degradable biomaterial, prepares and have the excellent modified plastics of degradability, and through be blow molded into have good every
Heat insulation, performance and the degredation plastic thin film such as toughness is big, intensity is high, and it is widely used in the covering material of hot house.
It is good that ethylene-vinyl acetate copolymer eva has good flexibility, the transparency and a lustrous surface property, and has very well
Resistance to low temperature, chemical stability is good, avirulence；Simultaneously good with the miscibility of filler.Nano silicon is a kind of nothing
Machine chemical materialss, are commonly called as white carbon, and its granule can sufficiently and uniformly can be distributed in resin material as packing material, can be complete
Resin-based materials performance is improved in face；As improved intensity and extensibility, improve wearability and the fineness improving material surface, and
Ageing resistace etc..Epoxy resin is widely used in the fields such as coating, binding agent, plastics, has weatherability and ultraviolet-resistent property, high machine
Tool performance and dimensional stability, solidification is convenient, adhesion is strong, toughness is good, modified after degradable, can decline in natural environment
Solution, will not be to environment.
The present invention has following beneficial effect: compared with prior art, the good modified plastics of degradable lower temperature resistance of the present invention,
Nano metal material carries out supersound process first, is allowed to be uniformly dispersed, and then adds in epoxy resin and PHA
Filler nanometer silicon dioxide, antioxidant and ethylene-vinyl acetate copolymer eva etc., on the one hand can keep the resistance to low of plastics
Warm nature, can control plastics to keep due life-span and function in non-abandoned again；Simultaneously because using biodegradation material,
When abandoning, molecular weight is reduced by oxidation reaction, be conducive to microbial decomposition.The good modification of prepared degradable lower temperature resistance
Plastics deep processing becomes plastic sheeting to be used for vegetable or flower shed, has that lower temperature resistance is good, good-extensibility and a life-span length, and
Can voluntarily degrade during abandonment, reduce to the advantages of the pollution of environment.
