Problems solved by technology

Among them, polycarbonate resin has good impact strength and transparency, but its processability is poor, so it is difficult to be made into complex products, and its chemical resistance is poor
Polymethyl methacrylate resin is widely used as an optical material because it has good optical properties, but its impact strength and chemical resistance are very poor
Polystyrene resins also have very poor chemical resistance and impact strength

Abstract

The invention discloses transparent plastic with antibacterial and mouldproof capacity and a preparing method thereof and belongs to the field of functional polymer materials and inorganic-organic nanocomposite. The transparent plastic is prepared from, by mass, 85-97% of transparent resin, 1-10% of antibacterial agent, 1-10% of mouldproof agent, 0.1-1.0% of complex antioxidant and 0.1-1.0% of dispersing agent. The preparing method comprises the steps of 1, conducting physical mixing according to mass percentage; 2, adding evenly mixed raw materials into a twin-screw extruder for melting granulation. According to the transparent plastic, light transmittance is larger than 85%, escherichia coli inhibition rate is larger than 99%, staphylococcus aureus inhibition rate is larger than 99%, and fungi-growth grade is 0. Furthermore, the preparing method is simple, implementation is convenient, and production cost is low.

Description

technical field [0001] The invention belongs to the field of functional polymer materials and inorganic-organic nanocomposite materials, and in particular relates to a transparent plastic with antibacterial and antifungal capabilities and a preparation method thereof. Background technique [0002] As a traditional pillar industry of the national economy, the home appliance industry plays an important role in economic development. At present, the proportion of plastics in home appliance materials is as high as 40%, and as home appliances become increasingly lightweight, miniaturized, personalized, specialized, high-performance, safe and environmentally friendly, the application of plastics will become more and more extensive. Home appliance parts made of steel have been replaced by plastic products. In addition, research into the development of transparent materials is making positive progress in order to introduce no-frills pop culture and pastel color culture into products...
