Description
Technical field
The present invention relates to a kind of special material for tube, and in particular to be a kind of polystyrene pipe PP Pipe Compound and its preparation side
Method.
Background technology
Under the stimulation that the industry requirements such as municipal works, construction industry, agricultural, industry continue to increase, plastic conduit industry obtains
The development of high speed is arrived.At present, the most commonly used field of Material of Plastic Tube in Our Country is mainly urban construction supply and drain water system, at me
State, in recent years with polyethylene pipe (PE), PA tube (PP), Polybutylene Pipe (PB), polystyrene tube (PS) and PAP
Etc. (PAP) the plumbing tubing sales volume lifting based on is very fast.The plastic pipe consumption figure in the domestic field in 2003 is up to 30
Ten thousand tons, and formd special material for tube, a complete industrial chain, many plastics are applied in tubular object extruding, municipal works
Tubing manufacturer also begins to be inclined to municipal works.
And as the continuous development and progress of science and technology, and people's living standard step up, " green " and " it is good for
Kang Anquan " turns into the most key two principal themes of modern.Therefore, the plastic conduit for being referred to as green tubing is increasingly chased after
Ask the concern of people from modern metropolitan cities of health and fashionable life.However, because current plastic pipe molding technology has still been short of,
Its out made plastic pipe (such as polystyrene pipe), whether rigid, flexible and stability, all also in one
Relatively low level, thus it is difficult to meet the needs of really actual.
The content of the invention
For above-mentioned technical deficiency, the invention provides a kind of polystyrene pipe PP Pipe Compound and preparation method thereof, have
Excellent rigid, flexible, toughness and stability.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of polystyrene pipe PP Pipe Compound, by the material composition that portion rate is values below：
Polystyrene regenerates broken material：80~90
Toughener：2~4
HDPE broken materials：3~5
Filler：4~6
EBS：0.2~0.5
Antioxidant：0.2~0.5
Coupling agent：0.4~3.5
Stearic acid：0.2~0.5.
Preferably, the toughener is SBS or SEBS.
Further, the filler is talcum powder.
Or the filler is mixed to get by wollastonite and talcum powder by portion rate for 1: 2.
Yet further, the coupling agent is titanate coupling agent.
Preferably, it is 2% to state the titanate esters adding proportion in coupling agent.
Further, the antioxidant is antioxidant 1010.
Based on above-mentioned basis, present invention also offers the preparation method of the polystyrene pipe PP Pipe Compound, including following step
Suddenly：
(1) polystyrene reworked material is cleaned, removes other the non-polystyrene contained in polystyrene reworked material
Material, metal and elastomer, are then dried and are homogenized；
(2) polystyrene reworked material and HDPE material are crushed respectively, and are together put into toughener in high mixer
Mix；
(3) after stirring 1~2min, EBS, antioxidant and stearic acid mixing are sequentially added, and be again stirring for 1~2min；
(4) filler after surface active is added, and continues 2~4min of stirring, the compound that then will be obtained after stirring
It is put into extruder；
(5) under 190~220 DEG C of extrusion temperature, the state for making compound to melt is expressed into insulation accumulator, is obtained
To polystyrene pipe PP Pipe Compound.
Specifically, in the step (4), the detailed process of filler surface active is：Add and fill out simultaneously in high mixer
Material and coupling agent, then under conditions of 80 DEG C, rotate 12~15min.
Further, in the step (5), before compound to be expressed into insulation accumulator, also using screen cloth to mixed
To close material to be filtered, and the screen cloth specification of first time filtering be 60 × 60 mesh, the screen cloth specification of second of filtering is 60 ×
80 mesh.
Compared with prior art, the invention has the advantages that：
(1) present invention starts with from the raw material for preparing polystyrene pipe, and the polystyrene reworked material of recovery is cleaned
With it is broken, and by appropriate Raw Material Blending Ratio and batch mixing order, various materials are mixed, so as to ensure that material
The effect of blending, the tube material, auxiliary agent, filler etc. for making to enter extruder can be uniformly wrapped on the table of polystyrene reworked material
Face, and then the modification to polystyrene material is realized, make it after polystyrene tube is produced, health, peace can not only be met
Entirely, green and the theme of environmental protection, and compared to in general plastic pipe, possessing more excellent rigidity, toughness and soft
Property, durability and practicality significantly strengthen.
(2) filler in the present invention uses talcum powder, and when preparing polystyrene pipe PP Pipe Compound, will using coupling agent
It carries out surface activation process, because talcum meal component is hydrated magnesium silicate, there is local accumulation phenomenon, and directly addition can influence to gather
The comprehensive mechanical property of styrene tubing, therefore, handled, contained in coupling agent molecule structure and talcum powder using coupling agent
The gene to chemically react, again containing the long key section that can be interacted with high molecular polymer, so as in filler and interlaminar resin
The Link role being mutually connected is generated, adds the affinity of two, improves the decentralization of talcum powder, and then can improve and carry
The comprehensive mechanical property of high-polystyrene tubing, moreover it is possible to reduce the cost of manufacture that tubing makes material.
(3) filler in the present invention can be also mixed to get by wollastonite and talcum powder according to 1: 2 portion rate, and with idol
Join agent mixing and after surface active, its rigidity and flexibility are more stronger than single filler.
(4) coupling agent in the present invention preferably uses titanate coupling agent, and titanate esters adding proportion is 2%, due to
Coupling agent can fully wrap up talcum powder, improve the decentralization of talcum powder so that and the impact strength of material has reached maximum,
Therefore, appropriate titanate esters adding proportion can reduce the impact strength of material to the full extent, ensure the mechanics of composite
Performance.
(5) antioxidant in the present invention preferably uses antioxidant 1010, can effectively prevent polymeric material long-term old
Thermal oxidative degradation during change, extend the life-span of polystyrene pipe PP Pipe Compound.
(6) toughener in the present invention is that styrene, butadiene, styrene block form using SBS or SEBS, SBS
Copolymer, there is the advantages of rubber and plastics, cold resistance, flexibility, elasticity, excellent heat resistance；And SEBS is with polystyrene
For end segment, the ethylene-butene copolymer for being hydrogenated with to obtain using polybutadiene is the linear tri-block copolymer of intermediate elastic block, tool
There are preferable UV stable, antioxidant and heat endurance.Therefore, from SBS or SEBS as toughener, with appropriate
After ratio mixes with other components, polystyrene pipe PP Pipe Compound can be made to possess excellent toughness and stability.
(7) although reworked material is through over cleaning, cleaning is that surface is clean, and material purity improves, parcel inside reworked material
Impurity is also difficult to remove completely, and therefore, before compound extrusion, the screen cloth for additionally using different meshes has been carried out twice the present invention
Filtering, filtering can fully remove the impurity included after compound melting, and then ensure the tubing of subsequent forming out because of nothing
Impurity and the characteristics of smooth surface, no concave-convex pit is presented, greatly improve the Forming Quality of tubing.
