Description
Technical field
The present invention relates to plastics modification technology field, be specifically related to a kind of to there is modified plastics of antibacterial and mouldproof performance 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
