Abstract
The invention discloses a kind of anti-aging HIPs plastics of bacteria mildew-proof and its processing technology, the anti-aging HIPs plastics of bacteria mildew-proof, including following raw material are prepared：75 95 parts of HIPs resins, 35 parts of SBS resins, 0.5 1.5 parts of polyvinyl alcohol, 0.3 3 parts of antioxidant, the anti-aging HIPs plastics of 0.05 0.5 parts of bacteria mildew-proofs of the invention of bacteria mildew-proof agent have well antibacterial, mould proof, thermo oxidative aging, anti-ultraviolet ageing, flame retardant effect, it is environmentally protective, nonhazardous pollutant discharges, and is suitably applied the fields such as appliance shell, part, automobile decoration piece, art work, daily necessities.
Description
Technical field
There are antibacterial, mould proof, antiageing effect HIPs plastics the present invention relates to a kind of.
Background technology
HIPs, is a kind of shock proof polyphenyl produced by adding the method for polybutadiene glue particle in polystyrene
Ethene.This polystyrene products can add micron order rubber grain and by the method for scion grafting polystyrene and rubber grain
Link together.When being impacted, the point stresses of crack propagation can be discharged by the rubber grain of flexible relative.Therefore split
The extension of line is hindered, and impact resistance is improved.Shock proof polystyrene have workability, good performance and
Low price, therefore be used to manufacture and permitted multiduty product and industrial products.Main application fields have packaging and disposable product,
Instrument and meter, household electrical appliance, toy and amusement article and building trade.It is high that HIPs resins in many fields instead of valency
Engineering plastics, but the photo-thermal stability of HIPS resins is not so good, and anti-aging property also has much room for improvement, and fire resistance is not high,
These problems limit the application of HIPS resins.In order to improve the application performance of HIPs resins, the present invention is preparing HIPs plastics
When with the addition of new zinc antiseptic, effectively increase antibacterial, the fungicidal properties of HIPs plastics.In order to improve the heat of HIPs plastics
The problem of mechanical property reduces after oxygen aging, the present invention with the addition of sisal fiber, effectively improve HIPs plastics in the feed
