Existing crackle, the plate surface in comparative example 1 can see apparent crackle, it can be seen that, coat a strata aniline in plate surface
Film layer can enhance the resistance to low temperature of plank.
Secondly, obtained by embodiment 3 and the data comparison of comparative example 1, by polyaniline-coated processing plank without
The plank of polyaniline-coated processing is compared, oxygen index (OI) increase, fire protection flame retarding coefficient higher；And the plank table after polyaniline-coated
Face electric conductivity enhancing, surface resistivity reduce, and have better antistatic property；It can by the comparison of embodiment 3 and comparative example 2
Know tourmaline powder, the addition of vermiculite power the release of fungistatic effect and anion has been served it is conclusive.By embodiment 1-5 with
The Contrast on effect of comparative example 1~2 can be seen that stretching of the addition of polyaniline-coated and tourmaline powder, vermiculite power to plank
Intensity and impact strength have no significant effect.
