Abstract
The present invention relates to a kind of anti-scribble engineering thermoplastic material plate and its preparation and application, the plate that the plate is formed with engineering thermoplastic material substrate and polymetylmethacrylate, Kynoar PVDF.Plate is prepared using the co-extrusion mode or multi-layer coat hanger pattern coextrusion head mode of individual layer rack type die.The present invention is applied to aviation interior material, has preferable weatherability and anti-scribble performance.
Description
Technical field
The invention belongs to anti-scribble material and its preparation and application field, more particularly to a kind of anti-scribble engineering thermoplastic material
Flitch material and its preparation and application.
Background technology
As aviation interior material, such as cabin side lining, seat or small table plate, the fire-retardant mark of aviation primarily met
Standard, the FAR25.853 and OSU65/65 of typical laws and regulations requirement such as American Association Directorate of Air.Secondly in daily use
In the process, except meeting necessary mechanical property, such as height stretches and bending modulus, outside shock resistance, it is necessary to meet easily clear
It is clean, the requirement of anti-scribble and aesthetics aspect.
The thermoplastic engineering plastic of the high performance such as polycarbonate has had been applied in a variety of industrialization fields at present, such as navigates
Empty space flight, track traffic, electronic apparatus and security protection.Since it possesses excellent flame retardant property, high impact resistance is a large amount of at present
Apply in aviation interior trim field, such as framed side wallboard, ceiling, seat back etc..But since its case hardness is low, chemically-resistant
The shortcomings of product corrosivity is poor would generally carry out spray treatment on its surface when practical application or stick a kind of fluorination
The film of object, such as polyvinyl fluoride or Kynoar.Spray treatment is not environmentally friendly processing mode, Er Qiecai
Material and human cost are expensive；Fluoride film is had excellent performance, but at present for cost it is very expensive, apparent availability is in short supply,
Again since fluoride materials surface can be relatively low, it usually needs additional binding agent could by it with base material polycarbonate adhesive one
It rises.Therefore, market in urgent need is a kind of meets fire-retardant aviation, mechanical property and surface property material and technical solutions.
The content of the invention
The technical problems to be solved by the invention be to provide a kind of anti-scribble engineering thermoplastic material plate and its prepare and
Using the plate has preferable weatherability and anti-scribble performance.
The anti-scribble engineering thermoplastic material plate of one kind of the present invention, the plate is using engineering thermoplastic material as base material
(engineering thermoplastic material such as polycarbonate here could alternatively be including but not limited to " polyphenylene thioether PPS ", " polyethers ether
Ketone PEEK ", " polyetherimide PEI ", " polyether sulfone PSU ", " polyphenylsulfone PPSU ", " polyformaldehyde POM " and " polyvinyl chloride
PVC " and its blend), the plate formed with polymetylmethacrylate, Kynoar PVDF.
The plate can be using polycarbonate as base material, and PVDF/PMMA blend compositions are for surfacing or with makrolon
PC is base material, and PVDF is surfacing, and PMMA is intermediate layer material.
The PVDF/PMMA blend compositions are top surface or upper and lower surface material.
The thickness of the polycarbonate is 0.5~5 millimeter.
The thickness of the PVDF/PMMA blend compositions is 20~100 microns.
The PVDF is surfacing, and thickness is 20~100 microns；PMMA is intermediate layer material, and thickness is micro- for 10~50
Rice.
The plate is two layers, three layers or five-layer structure material.
A kind of preparation method of anti-scribble engineering thermoplastic material plate of the present invention, including：Using individual layer clothes hanger pattern
Plate is prepared in the co-extrusion mode or multi-layer coat hanger pattern coextrusion head mode of head.
A kind of application of anti-scribble engineering thermoplastic material plate of the present invention, the anti-scribble engineering thermoplastic plate of material
Application of the material as aviation interior material.
Material：
Makrolon (PC) blend composition, this kind of material market is more sufficient at present, such as the transnational enterprise of SABIC, Convestro
Industry has the power PC blend composition of a great variety.
Polymethyl methacrylate (PMMA) is a kind of widely used material, there is substantial amounts of PMMA and PC currently on the market
Coextrusion plate, substantial amounts of experiment and practical application show that the co-extrusion plate of PMMA/PC has good caking property.Except this
Outside, the compatibility of PMMA and PVDF are very good, can dissolve each other to a certain extent.At present, there are more and more researchs
The performance and characterization of PMMA and PVDF intermingling materials and coextrusion material.
Kynoar (PVDF) can provide preferable weatherability, anti-flammability, endurance and property easy to clean.But due to it
Surface can be relatively low, it is difficult to be bonded together well with polycarbonate substrate.
The present invention solubilizer of other high performance thermoplastics and PVDF such as using PMMA as PC, it is same by coextrusion
When squeeze out the blend composition of PC and PVDF/PMMA or co-extrusion PC/PMMA/PVDF trilaminate materials or PVDF/PMMA/PC/
Five layer materials of PMMA/PC, the final representation of made plate are：
1) PC be base material, about 0.5~5 millimeter；PVDF/PMMA blend compositions are surfacing, can be one layer of upper surface, also may be used
For two layers of upper and lower surface, thickness is about 20~100 microns.
2) PC be base material, about 0.5~5 millimeter；PVDF is surfacing, and thickness is 20~100 microns, and PMMA is interlayer
Material, thickness are 10~50 microns.
Coextrusion：
Current plate or the coextrusion of film be divided into melt distributor add individual layer rack type die co-extrusion mode and
Multi-layer coat hanger pattern coextrusion head.Melt distributor adds the co-extrusion mode of single layer die for more traditional coextrusion processes, still
It, may be due to the hot property of material and the difference of Melt Flow Viscosity since different materials begin to contact after distributor
Flowing instability is caused, the problems such as thickness distribution is uneven, causes this configuration mode to melt flow channel particularly single layer die
The requirement of inner cavity runner is very high.The coextrusion mode of multi-layer coat hanger pattern head, different materials pass through different melt flow channels
Into die head inner cavity, until the position of die lip just converges to together, avoid due to material hot property or mobile performance difference
The problem of may causing is a kind of relatively new type extrusion way.Two kinds of coextrusion modes can be selected the present invention in principle
It selects, it is preferred that the coextrusion mode of multi-layer coat hanger pattern head.
Advantageous effect
The anti-scribble engineering thermoplastic material plate of gained of the invention has preferable weatherability and anti-scribble performance, can meet
The FAR25.853 even requirement of OSU65/65；
Weatherability：As 1000hr xenon lamp aging after, yellowing changing value is less than 1, is even less than 0.5, and general PC plate
It is about 20 in 1000 aging post yellowing values；
Anti- scribble performance according to the test of ASTM D6578-08 or NF F 31-112, can easily use isopropanol, and two
Toluene or methyl ethyl ketone cleaning scribble, including alkaline coating, acid coating, permanent marking pen and wax crayon, and after cleaning
Surface is without cracking.
