Description
Technical field
The present invention relates to diaphragm field, more particularly to a kind of outdoor section bar diaphragm and preparation method thereof.
Background technology
With social development, requirement of the people to construction material particularly facade is intended to more three-dimensional, color
Color, patterning.The conventional exterior trim section bar of building mainly has two kinds of aluminium alloy and plastic-steel, passes through a variety of coloration process
To reach that surface color enriches, pattern color effect true to nature.However, outdoor wind, Exposure to Sunlight, rain such as beat at the nature adverse circumstances
The colour image of section bar outer layer is occurred the phenomenons such as fade, peel off quickly, leverage exterior trim image.Asked to solve this
Topic, is generally cladded with upper protective film in colour image.
At present, the high-quality section bar diaphragm product on domestic market is offshore company's production, and domestic diaphragm is basic
All designed using individual layer PVC film, cause weatherability poor, service life is very short.So, the country is in high-quality this side of section bar diaphragm
Face is still in the technological gap stage, so as to allow offshore company to form monopolization situation.Therefore, develop a kind of weatherability, resistance to ag(e)ing,
The superior performances such as barrier, high-quality outdoor section bar diaphragm are very necessary.
Kynoar (PVDF), has the characteristic of fluororesin and resins for universal use concurrently, with good chemical resistance, resistance to
High temperatures, oxidative resistance, weatherability, the radiance of resistance to ray.It is bonded and is closed with the carbon compound of fluorine one in chemical constitution, it is this with short
The structure of key matter forms most stable most firm combination with hydrogen ion thus fluorocarbon coating has special physical chemistry
Can, not only there is very strong wearability and shock resistance, and extremely harsh with having very high anti-colour fading in rugged environment
Property and anti-ultraviolet property.Kynoar (PVDF) is semi-crystalline polymer, and fusing point is high, and surface tension is small, and transparency is inadequate,
And cost of material is high.And polymethyl methacrylate (PMMA) itself has excellent optical characteristics and weatherability, light transmittance pole
It is good, it is most excellent macromolecule transparent material at present.Due to the effect of hydrogen bond, Kynoar (PVDF) and polymethylacrylic acid
Methyl esters (PMMA) compatibility is fine.How a kind of diaphragm is obtained, and it is ensureing that it has excellent mechanical property and physico
Have good ultraviolet-absorbing and light transmission while learning performance concurrently, and there is compared with like product relatively low cost,
It is significant in industry.
The content of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, there is provided a kind of outdoor section bar diaphragm and its preparation
Method.
The technical solution used in the present invention is：A kind of outdoor section bar diaphragm, it is had by material quality percentages
Following component：50~90% modified polymethyl acid ester resin, 5~50% polyvinylidene fluoride resin and 1~5% purple
Ultraviolet absorbers.
Specifically, the addition of ultra-violet absorber directly affects barrier property of the final products to ultraviolet, when it adds
When dosage is limited to 1~5%, it may be such that there is final products stable UV protection barrier property effectively to control cost simultaneously.
As the further improvement of such scheme, the ultra-violet absorber is selected from salicylic acid esters, benzophenone class, benzo three
At least one of azole, group-substituted acrylonitrile, triazines and hindered amines.The preferred salicylate of ultra-violet absorber of the present invention
Class, benzophenone class, benzotriazole and triazines, much further preferably from 2- (2- hydroxy-5-methyl bases phenyl)-BTA, double
Bisphenol a disalicylate, 2,2 '-dihydroxy -4,4 '-dimethoxy-benzophenone, 2- (2 '-methyl -4 '-hydroxy phenyl)-benzo
In triazole, the chloro- 6- of 2,4- bis- (4- morpholinyls) -1,3,5-triazines and 2- (2 '-hydroxyl -5 '-tert-butyl-phenyl)-BTA
It is at least one.
As the further improvement of such scheme, the modified poly (methyl methacrylate) is through toughening agent modified poly- first
Base methyl acrylate.Further, the toughener is selected from esters of acrylic acid rubber, styrene ethylene butadiene-styrene
Copolymer, fluorubber, polyurethane elastomer, MBS terpolymer, ethyl vinyl acetate second
At least one of enoate copolymer and haloflex.
As the further improvement of such scheme, thicknesses of layers scope is 10~70 μm.Specifically, according to protecting object not
With the climatic environment different with being in, specific aim carries out thickness regulation both escapable costs, and protecting effect is can reach again.
A kind of preparation method of outdoor section bar diaphragm as described above, each component is total to by it by material quality percentages
After mixed processing in input extruder, through T-shaped or rack type die melting extrusion, melting extrusion temperature control is in 160~250 DEG C of models
In enclosing, die head temperature is controlled in the range of 200~260 DEG C, by cooling, winding, obtains finished product.
The beneficial effects of the invention are as follows：
(1) present invention melts coextruded layer monofilm by the way that modified poly (methyl methacrylate) and Kynoar are compounded,
Optimize the wherein characteristic of modified poly (methyl methacrylate), the addition of ultra-violet absorber and thicknesses of layers simultaneously so that system
Not only there are good UV absorbing properties and light transmission for the diaphragm gone out, while having excellent pressing, corrosion resistant
Corrosion, solvent resistance, resistance to soiling, wearability, self-cleaning, weatherability, durability and good mechanical property, can persistently effectively
Protection type wood color is color.
(2) preparation method technique of the invention is simple, it is easy to control, and the prepared product obtained has good steady quality
Property, and the more international like product of production cost is relatively low, has filled up the blank of domestic high-quality outdoor section bar diaphragm.
