TABLE 1
/>
Referring to the results in table 1, it can be seen that the nylon material prepared by adopting the specific type of organosilicon monomer in the embodiment of the invention has good flame retardance, excellent anti-dripping performance and better mechanical property. Although the organic silicon monomers are also polymerized in the comparative examples 1 and 2, the anti-dripping performance of the organic silicon monomers is poor, and dripping ignition still occurs; and the flame retardance and tensile strength of the nylon material are also worse than those of the example nylon material.
Further referring to the results of examples 1 to 1-3 and Table 1, it is understood that the nylon material of the examples of the present invention exhibits good anti-dripping performance at a mass ratio of nylon salt to silicone monomer of 100:1, i.e., good anti-dripping performance can be obtained by adding only a small amount of silicone monomer.
Comparing the characterization results of examples 1 to 9-1, it is seen that the nylon materials of examples 3, 3-1, 8-1, 9-1 have higher limiting oxygen index and tensile strength with the same amount of the silicone monomer, and thus the silicone monomer is preferably methylphenyl dimethoxy silane, cyclohexyl ethyl dimethoxy silane and dicyclohexyldimethoxy silane, and more preferably cyclohexyl ethyl dimethoxy silane and dicyclohexyldimethoxy silane.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
