Effect of Nano SiO2 on Pyrolytic Reaction of Phenol-Formaldehyde Resin
Phenol-formaldehyde resin is used as the most adhesive to produce waterproof plant-based composite. However, this product contains phenol and formaldehyde which can be easily released to pollute air. Based on the single-factor method, the effect of nano SiO2 on situation of pyrolytic reaction of PF resin was studied by Py-GC/MS. The results were shown that the components of PF by Py-GC-MS analysis were carbon dioxide(83.54％), D,.alpha.-tocopherol (12.55％), 1,3-bis(trimethylsilyl) benzene (1.96％), phenol(1.95％). And the results were shown that the main components of PF/SiO2 composite by Py-GC-MS analysis were as follow: carbon dioxide(60.37％), 2-butanamine(14.41％), fluoxetine (12.09％), 2,6,10-dodecatrien-1-ol, 3,7,11-trimethyl-, acetate, (E,E)-(3.38％), bis(2-ethylhexyl) phthalate(3.35％), phenol, 2-methyl-(3.12％), phenol(2.39％), 2-propanamine(0.89％). The result showed that nano SiO2 could effectively delay the pyrolysis of PF resin.
