The various aspects of the national economy such as agricultural, automobile, communication and building.With the continuous compression of existing space resource, consumer couple
Class material is restored using more and more in folding, this kind of product does not require nothing more than foldable storage, and use can be decontroled after expansion, and
And have some strength support, for example infant bathtub, folding containing box etc., current existing polypropylene material reach such not yet
It is required that the present invention is just to provide for a kind of foldable, high restoration modified polypropylene material, it is allowed to be successfully applied to portable
In household products.
Invention content
Based on this, a kind of foldable, height are provided it is an object of the invention to overcome in place of above-mentioned the deficiencies in the prior art
Restoration PP composite material.
To achieve the above object, the technical solution used in the present invention is：A kind of foldable, high restoration polypropylene composite materials
Material includes the ingredient of following parts by weight：50~80 parts of polypropylene, 5~20 parts of elastomer, 15~30 parts of polybutene.
By the way that polybutene, elastomer and polypropylene is composite modified in the present invention, according to similar compatibility principle, elasticity is utilized
Body is acted on as bridge bridge joint, respectively with polypropylene and polybutene partially compatible, increases the compatibility of composite material, keeps gained poly-
Acrylic composite has the characteristics that foldable, high restoration, can be suitable for portable domestic product.
Preferably, the foldable, high restoration PP composite material, include the ingredient of following parts by weight：Poly- third
50~70 parts of alkene, 10~20 parts of elastomer, 20~30 parts of polybutene.
The polybutene of above-mentioned parts by weight, elastomer and polypropylene are composite modified, and gained PP composite material can be made to have
The characteristics of better foldable, high restoration.
It is highly preferred that the foldable, high restoration PP composite material, include the ingredient of following parts by weight：It is poly-
50~60 parts of propylene, 15~20 parts of elastomer, 25~30 parts of polybutene.
The polybutene of above-mentioned parts by weight, elastomer and polypropylene are composite modified, and gained PP composite material can be made to have
The characteristics of better foldable, high restoration.
Preferably, the elastomer is ethylene propylene diene rubber.One end of ethylene propylene diene rubber and polypropylene, the other end with it is poly-
Butylene can be good at compatible.
Preferably, the polypropylene is at least one of copolymer polypropylene, homopolypropylene.
Preferably, the polybutene is at least one of isobutene, n-butene.The addition of polybutene primarily serves easy to break
The effect of folded, high restoration.
Meanwhile the present invention also provides the preparation method of a kind of foldable, high restoration PP composite material, institutes
The method of stating is：Each ingredient is subjected to melting extrusion granulation at 190 DEG C~230 DEG C, foldable of the present invention is obtained, high restores
Property PP composite material.
Preferably, the melting extrusion granulation carries out in double screw extruder, the draw ratio of the double screw extruder
For (36~40):1.The selection of the double screw extruder draw ratio, not only can rationally disperse each component, but also be avoided that each component
It is degraded by high shear.
Compared with the existing technology, beneficial effects of the present invention are：
In foldable of the present invention, high restoration PP composite material, by by polybutene, elastomer and polypropylene
It is composite modified, so that gained PP composite material is had the characteristics that foldable, high restoration, portable domestic can be suitable for and produced
In product.
Specific implementation mode
To better illustrate the object, technical solutions and advantages of the present invention, below in conjunction with specific embodiment to the present invention
It is described further.
6 kinds of embodiments of foldable of the present invention, high restoration PP composite material, the present embodiment 1~6 and comparison
Foldable described in example 1, each Parts by Ingredients of high restoration PP composite material and folding force, bending strength conservation rate such as table
Shown in 1, wherein for the polypropylene in Examples 1 to 6 and comparative example 1 by taking PP EPC30R as an example, polybutene is but unlimited by taking PB as an example
In this；Wherein, PP EPC30R are polyacrylic a kind of product grade in the market；The test method of folding force of the present invention is：It will
2mm thickness square plate bends overlapping along center line completely, tests the bounce of material on outermost sideline, bounce is bigger, explanation
It folds more difficult；The test method of bending strength conservation rate is：It is first according to 178 standard sample preparations of ISO and test, primary data
Beginning batten test value will test bending strength value after being then bent batten by the positive and negative bending in 90 ° of angles 20 times, and conservation rate is to be bent
Numerical value/initial value * 100% afterwards.
The each component parts by weight and folding force of 1 Examples 1 to 6 of table and comparative example 1, bending strength conservation rate
The preparation method of foldable, high restoration PP composite material described in the embodiment of the present invention 1~6 and comparative example 1
For：By each ingredient draw ratio be (36~40)：Melting extrusion granulation, extrusion temperature 190 are carried out in 1 double screw extruder
DEG C~230 DEG C, obtain foldable, high restoration PP composite material described in the embodiment of the present invention 1~6 and comparative example 1.
As it can be seen from table 1 compared with comparative example 1,1~6 foldable of the embodiment of the present invention, high restoration polypropylene
