Description
Technical field
The present invention relates to a kind of plastics and manufacture method thereof.
Background technology
The nineties in last century China particularly northern area once used some PVC profile to do door and window on a large scale, but due to the weatherability problem of unresolved key, add that the formula that each producer uses is lack of standardization, turning yellow, becoming the typical aging phenomenon such as ash, weathering appears in door and window to cause the people to find after being used for a while, very large to this suggestion, have impact on promoting the use of of PVC door and window.And see the countries such as American-European conversely; due to the relatively morning of carrying out the research of weatherability this respect; development is ahead of us greatly; the door and window of the outdoor use of the many countries of present America and Europe is also mostly the material using PVC, namely elegant in appearance, maintenance easy to clean again; its a large amount of uses; effectively can reduce the felling of trees, protect the earth that we depend on for existence, really accomplish low-carbon (LC) and low emission.The weather-proof product of low side domestic is now after xenon lamp irradiates 200 hours, the color aberration Δ E of sample just <5, this is well below the standard of foreign country: after xenon lamp irradiates 4000 hours, the color aberration Δ E<5 of sample, this is that I takes charge of the requirement of developing this product.
Therefore, carry out the research to PVC material weatherability, not only can expand the range of application of PVC plastic, the good life of the people can also be beautified, the main trend of world's energy-saving and emission-reduction can be complied with again.
Igelite is divided into PVC-U and flexible PVC two kinds, and PVC-U has good tension, bending resistance, resistance to compression and impact resistance, can be used as structural material separately.The flexibility of flexible PVC, elongation at break, cold resistance can increase, but fragility, hardness, hot strength can reduce.Therefore its soft durometer is suitably regulated can to change toughness and the rigidity of polyvinyl chloride, to reach our demand.Polyvinyl chloride also has good electrical insulation properties, can make low frequency insulating materials, and its chemical stability might as well.But because the heat endurance of polyvinyl chloride is poor, long-time heating can cause degraded, and release HCL gas, make polyvinyl chloride variable color, so its range of application is narrower, serviceability temperature is generally between-15 ~ 55 degree.Polrvinyl chloride product in normal use, is also easily subject to the impact of natural conditions at occurring in nature, degradation reaction occurs, and makes products appearance variation, degradation, has a strong impact on the normal use of goods.Therefore, the weather resistance of polrvinyl chloride product be improved, in theory, stop the degraded of polyvinyl chloride exactly.
Raw material, composition and engineering are the main factors affecting PVC decorative material weatherability difference, are also deciding factors.PVC product in use, owing to being subject to other material comprehensive functions in occurring in nature light, heat, oxygen, moisture and air, there is signs of degradation, HCl can be released, produce conjugated double bond look group, make PVC material present metachromatism, after our PVC material often seen that Here it is uses certain hour, can turn yellow dimmed reason.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of weather-resistant decoration material that effectively can stop the degraded of polyvinyl chloride, that in use can effectively prevent metachromatism from occurring and manufacture method thereof.
Weather-resistant decoration material of the present invention is achieved in that and is composited by PMMA film sheet and PVC film sheet, and wherein, the composition of PVC film sheet comprises:
PVC, 100 weight portions;
Stabilizing agent, 1-3 weight portions;
AS, 1-156 weight portions;
Acrylate, 0.1-4 weight portions;
In-lubricant, 0.1-2.5 weight portions;
External lubricant, 0.05-1 weight portion;
Antioxidant 1010,0.05-2 weight portions;
Irgasfos 168,0.1-2 weight portions;
2-(2 ˊ-hydroxyl-5 ˊ-aminomethyl phenyl) BTA, 0.1-2 weight portions.
The present invention is achieved in that according to the weather-resistant decoration material manufacture method of above-mentioned prescription and is made up of the production process of PVC film sheet, PMMA film sheet and PVC film sheet recombination process, wherein,
(1) production process of PVC film sheet comprises successively:
Metering, high-speed stirred, preliminary melt prepared by banbury, 1# mill is plasticated, 2# mill refining, filtration, calendering main frame, cooling, rolling,
(2) PMMA film sheet and PVC film sheet recombination process comprise successively:
Preheating, laminating cooling, rolling.
The processing of PVC plastic glue needs to add more material, and often kind of material also has considerable kind for selecting.From the mechanism that plastic light is aging, mainly contain following content:
A, light stabilizer, the present invention adopt ultra-violet absorber and antioxidant composite, according to high polymer light degradation mechanism, light degradation mainly ultraviolet radiation causes strand to ionize, final generation free radical, and then cause series of oxidation degradation process, the present invention is from minimizing ultraviolet radiation and stop oxidation reaction and start with, adopt ultra-violet absorber and antioxidant composite as light stabilizer.Selecting of ultra-violet absorber must consider its absorption spectrum, though the energy of short wave ultraviolet is high, in PVC, conventional absworption peak is positioned at the UV-531 ultra-violet absorber of shorter wavelength, and natural daylight intermediate waves ultraviolet only has a little part, and conventional simulation accelerated test is also adopt the ultraviolet light compared with the 340nm of long wave, experimental results demonstrate, adopt UV-351 ultra-violet absorber poor effect, this should must reselect ultra-violet absorber.The present invention selects UV-P, and it is an effective UV light absorbers, effectively can absorb the ultraviolet light of 290-400 nanometer, prevent ultraviolet light to destroy organic macromolecule, effectively prevent the change of PVC decorative material physical property.Antioxidant we adopt hindered phenol antioxygen and phosphorous acid kind antioxidant, the former effective group is the hydroxyl between the tert-butyl group, Main Function ensures that the product later stage in use stablizes, the useful effect group of the latter is three valent phosphors, it can suppress the xanthochromia in process, both use, and have good synergy.
The use of B, titanium dioxide, the effect of titanium dioxide is two sides, on the one hand, titanium dioxide is good ultra-violet absorber, screener, to fast light good action, on the other hand, owing to inevitably there is crystallographic surface defects in titanium dioxide, to catalytic oxidation be caused, have a negative impact to fast light.The present invention intends adopting rutile type titanium white that is inorganic or organic coating accordingly.
The use of C, anti-impact modifier, unavoidable use anti-impact modifier in hard PVC, but the anti-impact modifier of routine often adopts the composition containing rubber phase, the appearance of double bond is always had in strand, double bond causes light resistance to become bad, adopts not double bond containing anti-impact modifier to address this problem.
(2) the weatherability plane materiel of PVC surface is fitted in
Select that hardness is higher, the good PMMA fabric of weatherability, be fitted in the weather resistance that PVC surface contributes to improving PVC.The light fastness of PMMA itself is very outstanding.
The present invention compared with the prior art, PVC film sheet composition is adjusted owing to have employed the multiple merga pass of PMMA film sheet and PVC film sheet, promote the performance of PVC film sheet, therefore, there is advantage that effectively can stop the degraded of polyvinyl chloride, that in use can effectively prevent metachromatism from occurring.
