A kind of modified recycling PP of isomerism cross-linking method containing L-POSS crosslinking agent and preparation method thereof is related to a kind of plastic material and preparation method thereof, and method of modifying of the present invention is: first will recycling PP forced air drying 3~4 hours under the conditions of 80 DEG C;Homemade micro- crosslinking masterbatch are first put into Universalpulverizer and place into planetary ball mill to grind and reach 10~50 μm up to being crosslinked the partial size expected, then weigh dried recycling PP by weight ratio, 4~6min of high-speed mixer and mixing is put into homemade micro- crosslinking masterbatch, toughener, inorganic filler, with double screw extruder at 160 DEG C -230 DEG C extruding pelletization up to reworked material.Technical solution of the present invention can realize the effect of the mechanical properties MODIFIED PP such as enhancing, toughening simultaneously, and being introduced into for isomerism cross-linking method is not necessarily to that compatilizer is added or keeps the performance of reworked material fine in the regenerative process that can make MODIFIED PP.
Description
Technical field
The present invention relates to a kind of plastic materials and preparation method thereof, contain the same of L-POSS crosslinking agent more particularly to a kind of
Modified recycling PP of matter isomery cross-linking method and preparation method thereof.
Background technique
Polypropylene is a kind of thermoplastic resin as prepared by propylene polymerization, be kind most light in current all plastics it
One, it is nontoxic, odorless, tasteless, have excellent surface rigidity, impact strength and the characteristics such as anti-scratch, and ring is not present in PP
Border stress cracking problem, so polypropylene is widely used in packing film, electrical equipment, field of furniture.
With the expansion of polypropylene application field and the increase of usage amount, waste and old polypropylene is also growing day by day, and waste and old poly- third
Degradation with aging occurs for alkene, and physical property is also greatly limited, is only used for far away from virgin material polypropylene, its application
Make the product of low performance.Can waste and old polypropylene regeneration use, be more advantageous to the sustainable development of plastic industry, will it is waste and old gather
Propylene regeneration has not only been able to satisfy demand of the market to polypropylene pipe, but also can solve environmental problem, has saved for manufacturing polypropylene pipe
About resource, therefore waste and old polypropylene recycling modification technology is the basic of solution problem above.
Recycling PP needs a kind of crosslinking agent of excellent properties to be modified it, therefore we have synthesized a kind of silicon containing L-POSS
Alkane crosslinking agent is modified it.L-POSS is a kind of siloxanes with trapezium structure, and it is in inorganic that molecular structure, which is with Si-O,
Core is constituted, this molecular structure with being keyed the trapezoidal network molecular structure to be formed containing the biggish Si-O key of bond energy and Si-C
With good high temperature resistant and mechanical property, the Si-H in molecular structure can be with the ethylene base junction in vinyl silanes crosslinking agent
It closes and forms the silane crosslinker containing L-POSS, since this crosslinking agent contains L-POSS and silane composition simultaneously, this is one
Kind has both the crosslinking agent of the two performance, i.e., has the novel crosslinker of high temperature resistant and cross-linking properties simultaneously, and satisfaction changes PP
Property recycling.
Summary of the invention
The modified recycling PP of the isomerism cross-linking method that the purpose of the present invention is to provide a kind of containing L-POSS crosslinking agent and
Preparation method, the present invention are mentioned by recycling PP with the isomerism cross-linking method containing L-POSS crosslinking agent is modified to reach
The purpose of height recycling PP mechanical property, technological operation is simple and can produce recycled plastic in enormous quantities, meets market
Industrial requirement and sustainable development.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of modified recycling PP of the isomerism cross-linking method containing L-POSS crosslinking agent, contains L-POSS silane crosslinker
Structural formula is as follows:
。
A kind of modified PP that recycles of isomerism cross-linking method containing L-POSS crosslinking agent includes based on mass weight part:
100 parts of PP of recycling；
3~10 parts of toughener；
10~30 parts of crosslinking masterbatch；
5~10 parts of inorganic filler.
The modified recycling PP of a kind of isomerism cross-linking method containing L-POSS crosslinking agent, the crosslinking masterbatch are
It is made of A material B material and production aqua three parts；
A expects composition: PP
Silane crosslinker containing L-POSS；
Initiator (cumyl peroxide (DCP))；
B expects composition: PP
Catalyst (dibutyl tin dilaurate)；
Antioxidant (antioxidant 1010)；
Produce aqua composition: acid and metal oxide are with the mixing of (1:1) ratio.
The modified recycling PP of a kind of isomerism cross-linking method containing L-POSS crosslinking agent, the L-POSS silane
Crosslinking agent is the method that polyaddition reaction occurs with L-POSS and vinyltrimethoxysilane, and the silane synthesized is derivative
Object；Inorganic filler is at least one of calcium carbonate, talcum powder, preferably calcium carbonate；Initiator be benzoyl peroxide (BPO) and
At least one of cumyl peroxide (DCP), preferably cumyl peroxide.
The modified recycling PP of a kind of isomerism cross-linking method containing L-POSS crosslinking agent, the toughener are
At least one of POE, polyvinyl acetate emulsion, polyvinyl alcohol, preferably POE；Antioxidant is antioxidant 1010, antioxidant 1076
At least one of, preferred antioxidant 1010；Catalyst is dibutyl tin dilaurate, triethylamine, Tri-n-Propylamine, three positive fourths
Amine, N, at least one of N- dimethyl butylamine, preferably dibutyl tin dilaurate；Producing aqua is acid and metal oxide with one
Certainty ratio mixing, preferably stearic acid and zinc oxide.
A kind of preparation method of the modified recycling PP of the isomerism cross-linking method of the crosslinking agent containing L-POSS, comprising the following steps:
A, 95 parts of A material are weighed by mass fraction, is put into extruding pelletization in double screw extruder after 4.5 parts of B material mixing, then
It is uniformly mixed again with 0.5 part of production aqua and is put into extruding pelletization in double screw extruder and forms micro- crosslinking masterbatch；
B, micro- crosslinking masterbatch in the portion A are first put into Universalpulverizer and place into grinding in planetary ball mill until crosslinking
Until the partial size of material reaches 10~50 μm；
C, PP will be recycled forced air drying 3~4 hours under the conditions of 80 DEG C, by weight ratio by micro- crosslinking masterbatch, toughening
