Abstract
The present invention is a kind of modified polypropene regenerated plastics and preparation method thereof, and components by weight percent is: waste polypropylene plastic 85～89 parts；SEBS4～5 parts；Maleic anhydride 0.8～1.2 parts；Grinding agent 0.5～1 part；Inorganic powder material 1～1.8 parts；Antioxidant 1.5～2 parts；Preparation method is, first waste polypropylene plastic, antioxidant and grinding agent is added in continuous mixer, and rotating speed is 600 turns/min so that it is mixing, then inorganic powder material and SEBS is added in above-mentioned pulpous state batch mixing, continues mixing, obtain even slurry；Weigh maleic anhydride, it is gradually added in the slurry being in stirring, it is allowed to mix homogeneously, open continuous mixer drain hole, the material stirred is drained into container dries in the air stand-by to room temperature, obtaining modified polypropene regenerated plastics, the modified polypropene regenerated plastics that the present invention prepares in intensity, toughness, glossiness and are all improved in terms of service life.
Description
Technical field
The present invention relates to a kind of modified polypropene regenerated plastics processing technique field, particularly relate to a kind of modified polypropene again
Raw plastics and preparation method thereof.
Background technology
Plastics are meeting people's life and social development as product important in high molecular synthetic material, plastics industry
Society and environmental problem that simultaneously as plastic refuse increases severely, " white pollution " caused causes are the most serious, but
Regenerated plastics also exist the shortcomings such as intensity is low, immalleable, glossiness is low, thermo-oxidative stability is poor, additionally, due to polypropylene macromole
Have tertiary carbon atom on chain, storing, during processing and routine use, can be heated, the effect such as light and oxygen and easily occur aging
Degraded, has a strong impact on the life-span of goods so that there is certain restriction effect in the scope recycling it and field.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of modified polypropene regenerated plastics and preparation side thereof are provided
Method.
The present invention for achieving the above object, by the following technical solutions: a kind of modified polypropene regenerated plastics, its feature exists
In, it is made up of the raw material of following parts by weight:
As preferably, described grinding agent is polypropylene wax.
As preferably, described inorganic powder material is barium sulfate.
As preferably, described antioxidant refers to one or both in antioxidant 1010 and antioxidant 168.
The preparation method of a kind of modified polypropene regenerated plastics that the present invention provides, it is characterised in that comprise the following steps:
(1) waste polypropylene plastic, antioxidant and grinding agent being added in continuous mixer, rotating speed is 300～600
Turning/min, mixing time is 15～25 minutes, and waste polypropylene plastic is completely melted to be mixed as being all homogenized with antioxidant, grinding agent
Shape body；
(2) inorganic powder material and SEBS being added in the pulpous state batch mixing of step (1) gained, continue mixing, rotating speed is 400
～800 turns/min, obtain even slurry；
(3) weigh maleic anhydride, be gradually added to be in the step (2) of stirring, continue stirring 15 minutes, be allowed to mixed
Close uniformly, open continuous mixer drain hole, the material stirred is drained into and container dries in the air stand-by to room temperature, obtain modified poly-third
Alkene regenerated plastics.
The invention has the beneficial effects as follows: the modified polypropene regenerated plastics that the present invention prepares are equal in its intensity and toughness
Having a certain degree of lifting, in the modified polypropene regenerated plastics being configured to, inorganic powder material uses barium sulfate, prepares Gao Guang
The polypropylene regenerated plastics of pool degree, add the effective ways that antioxidant is its generation degraded of suppression, therefore add modified poly-
The service life of propylene regenerated plastics.
