Technical field
The present invention relates to modified material fields, more particularly to a kind of biodegradable polypropene composition and its preparation side
Method.
Background technique
Biodegradable plastic refers to the effect of a kind of such as bacterium, mould (fungi) and algae of the microorganism as existing for nature
And cause the plastics of degradation.Biodegradable plastic can be divided into complete biodegradable plastics and destructive biodegradable plastic two again
Kind.Wherein destructive biodegradable plastic currently mainly includes modified (or filling) polymer material of degradable substance, completely raw
Object degradative plastics is mainly by natural polymer (such as starch, cellulose, chitin) or agricultural and sideline product through microbial fermentation or conjunction
It is made at the macromolecule with biological degradability, such as thermoplastic starch plastic, aliphatic polyester, polylactic acid, starch/polyethylene alcohol
Deng belonging to this kind of plastics.But the strength of materials of biodegradable plastic is usually lower, simultaneously because its appearance color and gloss compared with
Difference, therefore its use scope is also unable to get and significantly promotes.
Summary of the invention
The object of the present invention is to provide a kind of biodegradable polypropene compositions and preparation method thereof.
Technical scheme is as follows:
A kind of biodegradable polypropene composition is prepared by following raw material components by mass fraction:
Further scheme, tension fracture elongation rate >=450% of the atactic copolymerized polypropene, notch impact strength >=
35J/m。
The compatilizer is polypropylene grafted maleic anhydride, vinyl-acrylate copolymer, the copolymerization of propylene acrylic acid ester
The mixing of one or both of object or ethylene-methyl methacrylate glycidyl ester copolymer.
The antioxidant is four [β-(3,5- di-t-butyl 4- hydroxy phenyl) propionic acid] pentaerythritol esters (1010), β-
The positive octadecyl of (3,5- di-tert-butyl-hydroxy phenyl) propionic acid (1076), three-(2,4- di-tert-butyl-phenyl) phosphite esters
(168), at least three kinds of mixtures in the double octadecyls (DSTDP) of thio-2 acid.
Another goal of the invention of the invention is to provide a kind of preparation method of above-mentioned biodegradable polypropene composition,
By 65-75 parts of atactic copolymerized polypropene, 10-20 parts of PBTA, 3-5 parts of compatilizer, 10-15 parts of polylactic acid and 0.5 part of heat stabilizer
It is added to mixed on low speed 3-5min in high mixer, then uniformly mixed material is added twin-screw extrude and is kneaded, squeezed
Out, final products are obtained after cooling and dicing.The extrusion temperature that section is wherein respectively squeezed out in double screw extruder is 150-160 respectively
℃、160-175℃、175-185℃、185-195℃、185-195℃、185-195℃、185-195℃、185-195℃、185-
195℃、190-200℃。
PBAT is tetramethylene adipate and the copolymer of mutual-phenenyl two acid bromide two alcohol ester in the present invention, has both aliphatic poly
The characteristic of object and aromatic polymer, existing preferable ductility and elongation at break are closed, there are also preferable heat resistance and impacts
Performance and excellent biological degradability.
Polylactic acid (PLA) is a kind of novel biodegradation material, with good biodegradability, energy after use
It is degradable by microorganism in nature, carbon dioxide and water are ultimately generated, it is free from environmental pollution.
So the present invention is by the way that degradable both synthetic resin of PBAT and polylactic acid are added into polypropylene matrix, from
And make the polypropene composition of preparation that there are biodegradable properties.In addition, due to not adding any natural polymer
Object is closed, therefore it is with good product appearance and processing performance, and product purity is higher.The compatilizer of addition can simultaneously
Guarantee that polymer raw material product has good compatibility, so that product has good mechanical property, has wide range of applications.
