Make foam cell be difficult avalanche, improve the pore density of makrolon material, triethanolamine can also balance the speed of foaming simultaneously,
Their effects of cooperating, the abscess making product is micropore, and micropore size and being evenly distributed.
(4) luffa vine generally belongs to agricultural waste material, but itself has good suppression to common bacterial classification
Bacterium activity, luffa vine is ground into powder by the present invention by charred medicinal herb with its property retained, is downloaded to modification with same jointly covering as the tea seed cake producing discarded object
On mulberry fibre and expanded perlite afterwards, then mix with Fanglun slurry cake, maleic anhydride, pure-acrylic emulsion, be incorporated into poly- carbonic acid
In ester foaming plastics, both can improve dispersion effect between other raw materials for the above-mentioned material and compatibility, impart this product again
Certain bacteriostasis, luffa vine and tea seed cake can also make with load lanthanum zinc oxide, load cerium titanium dioxide mating reaction simultaneously
The bacteriostasis property of this product is more excellent.
(5) the antibacterial makrolon foamed plastic of present invention preparation is microcellular plastics, and uniformly, density is low, matter for bubble
Amount is light, be a kind of have excellent mechanical performances, can antibacterial and can sound-absorbing new material, and employ the inorganic of larger proportion
Filler, reduces its production cost, and can consume impact energy well when being impacted in use, will not produce and collapse
Fall into, more traditional Merlon foamed plastic improves a lot, and can be widely applied to multiple fields.
