Description

A kind of high-intensity polypropylene antibacterial plastics
Technical field
The present invention relates to plastics field, particularly, the present invention relates to a kind of high-intensity polypropylene antibacterial plastics.
Background technology
Plastics have entered people's life more and more, but general plastics in use become easily infected by altogether and grow multiple-microorganism, comprise malignant bacteria, and people healthy brought to harm.Along with the further attention of people to health environment, the safety and sanitation of plastics have become the problem that everybody pays close attention to, and antibiotic plastic arises at the historic moment at this point.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-intensity polypropylene antibacterial plastics, and not only anti-microbial property is good for this poly(lactic acid) antibiotic plastic, also has higher intensity.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of high-intensity polypropylene antibacterial plastics, prepared by the raw material by following portions by weight: 100 parts of polypropylene, high density polyethylene(HDPE) 10-15 part, Low Density Polyethylene 10-15 part, antiseptic-germicide 0.6-1 part, oxidation inhibitor 0.2-1 part, compatilizer 05-0.8 part, dispersion agent 0.4-0.8 part, glass fibre 10-15 part; Wherein, described antiseptic-germicide is prepared from by the component of following portions by weight: chitosan 3-10 part, nano titanium oxide 15-25 part, nano zeolite 15-20 part, polyhexamethylene guanidine propionic salt 5-10 part.
Described oxidation inhibitor is comprised of Hinered phenols antioxidant and phosphite ester kind antioxidant, and the weight ratio of described Hinered phenols antioxidant and phosphite ester kind antioxidant is 2:1.
Described compatilizer is selected from least one in polypropylene grafted maleic anhydride, polypropylene grafted carboxylic acid, Chlorinated Polypropylene III.
Described dispersion agent is selected from least one in stearic acid, whiteruss, polyethylene wax.
Described antiseptic-germicide is prepared from by the component of following portions by weight: 8 parts of chitosans, 15 parts of nano titanium oxides, 15 parts of nano zeolites, 8 parts of polyhexamethylene guanidine propionic salts.
Compared with prior art, tool has the following advantages in the present invention: not only anti-microbial property is good for poly(lactic acid) antibiotic plastic of the present invention, also has higher intensity.
