Description
Technical field
The present invention relates to plastics modification technology field, be specifically related to a kind of aging-resistant of resistance to sunshine modified plastics and preparation method thereof.
Background technology
China is vast in territory, weather is complicated, plastic greenhouse is utilized to carry out the facility cultivation of vegetables, special vital role is served to the disparities between supply and demand alleviating vegetables dull seasons, there is significant social benefit and huge economic benefit, for the special plastics film of plastic greenhouse that agriculture production is built, require its transmittance, insulation, tension and the aspect such as ageing-resistant performance be all better than ordinary agricultural membrane, prior art cannot meet these requirements, need to conventional plastic in addition modification obtain modified plastics.Modified plastics refers on the basis of general-purpose plastics and engineering plastics, through filling, the method processing such as blended, enhancing, improves the plastics of the performance of the aspects such as flame retardant resistance, intensity, shock resistance, toughness.
Nano antimony tin oxide powder is the super-fine material that particle size is less than 100nm, it is a kind of N-type semiconductor material, compared with traditional antistatic material, nano antimony tin oxide powder has obvious advantage, being mainly manifested in the aspects such as good electroconductibility, weathering resistance, stability, light-coloured transparent and low infrared emittance, is the extremely potential Multifunction electro-conductive material of one and lagging material; Nanometer titanium dioxide, be the super-fine material that particle size is less than 100nm also known as nano titanium oxide, its outward appearance is fluffy white powder, has uvioresistant, antibacterial, self-cleaning, anti-aging effect.Applications to nanostructures is that the modification of polymer materials opens up a new way, also for design, preparation high-performance, multifunctional plastic are laid a good foundation, the interfacial energy of nano antimony tin oxide powder and nanometer titanium dioxide is very large, is in energy unsteady state.
For solving an above difficult problem, being necessary to prepare the comprehensive modified plastics of a kind of new function, through being blow molded into the plastics film with performances such as good heat-insulation and heat-preservation, toughness are large, intensity is high, and being widely used in the plastic greenhouse covering material of winter production vegetables.
Summary of the invention
Object of the present invention is just to provide a kind of aging-resistant of resistance to sunshine modified plastics and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of aging-resistant of resistance to sunshine modified plastics, it is characterized in that, be made up of the raw material of following weight part: polystyrene 35-45, polyvinyl chloride 55-65, nano antimony tin oxide 4.9-6.8, nanometer titanium dioxide 1-2, Macrogol 200 2-4, Aluminate 1-2, Cadmium Sulphate 0.2-0.4, polyoxyethylenated castor oil 1.1-2.3, brominated triazine 0.1-0.3, lead stearate 0.4-0.7, dehydrated alcohol are appropriate.
The preparation method of the described a kind of aging-resistant of resistance to sunshine modified plastics, is characterized in that comprising the following steps:
(1) by nano antimony tin oxide, nanometer titanium dioxide calcination processing 30-50 minute at 635-815 DEG C, there-necked flask is put in cooling, adds dehydrated alcohol, Aluminate stirs, reflux 4-5h, centrifugation, with absolute ethanol washing 2 ~ 3 times, vacuum-drying at 80 DEG C;
(2) by adding Macrogol 200 in the said products, lead stearate is uniformly mixed, obtained mixed powder;
(3) polystyrene, polyvinyl chloride are joined in high-speed mixing dispersion machine; add above-mentioned mixed powder, Cadmium Sulphate and other remaining component blending dispersion 15-20 minute, take out and pour in twin screw extruder, extrude by working specification; through granulator granulation, discharging.
The present invention has following beneficial effect: nano material is first added coupling agent stir-activating by the present invention, mix with grafting such as polystyrene, polyvinyl chloride, brominated triazine, polyoxyethylenated castor oils again, then granulation is melt extruded through twin screw extruder, obtained plastics resistance to sunshine anti-aging, tensile strength and resistance to impact shock significantly improves, work-ing life and resistance toheat also improve, deep processing becomes plastics film for green house of vegetables, have that lower temperature resistance is strong, effect of heat insulation obviously, self-cleaning antibacterial, transmittance advantages of higher.
