The invention provides a
mite-killing, degerming and deodorizing
polyurethane foam material and a preparation technology thereof, and relates to the technical field of
polymer materials. The
polyurethane foam material is mainly prepared from, by
mass, 900-1000 parts of polyether
polyol, 450-650 parts of
isocyanate, 20-100 parts of a chain
extender, 40-50 parts of water, 10-80 parts of
silicone oil, 2-3 parts of a
tin catalyst, 3-8 parts of an amine catalyst, 30-100 parts of
activated carbon, 50-100 parts of nanometer
titanium dioxide, 5-25 parts of
azadirachtin and 5-25 parts of
spirodiclofen, and a
mass ratio of the
azadirachtin to the
spirodiclofen is (1-2):(1-2), and preferably 1:1. The
mite-killing, degerming and deodorizing
polyurethane foam material solves the technical problems of low
mite killing and degerming efficiency and short effect keeping time of existing polyurethane foam materials, can adsorb
formaldehyde gas and peculiar smells, and also can fundamentally kill
bacteria and remove mites, so the mite-killing, degerming and deodorizing polyurethane foam material provides guarantee for the health of people.
