Sodium hydroxide solution hydrolyzes vinyl neodecanoate under alkaline condition and generates neodecanoic acid and vinyl alcohol, is subsequently added into four fourth of metatitanic acid
Ester generates nano-titanium dioxide, and in the generating process of nano-titanium dioxide, vinyl alcohol destroys-Ti-O-Ti- network structure
Formation, and titanium dioxide fine particles surface formed absorption thin layer so that generating certain sky between nano titanium dioxide particles
Between steric hindrance, inhibiting effect is played to the reunion of nano titanium dioxide particles, reduces the surface of titanium dioxide nanoparticle
Power, and then dispersion stabilization of the nano-titanium dioxide in phenolic resin is significantly improved, in addition, by vinyl alcohol modification
After nano titanium dioxide particles afterwards are evenly dispersed between resin, play the role of being equivalent to " lubricant ", greatly reduce
The abrasion probability of polymeric matrix, meanwhile, the particle of nano-dispersion makes to generate a degree of net between polymer molecular chain
Shape crosslinking, significantly improves wearability of the invention；In addition, the new certain herbaceous plants with big flowers acid generated is dispersed in resin, the bulk contained is lazy
Property alkyl structure can absorb ultraviolet energy, being converted into warm-up movement discharges energy, with nano-titanium dioxide have synergistic
Effect, mutual cooperation effect, has the function of absorption ultraviolet light stable for a long time, the function in resin can be protected as umbrella
Group by the attack of ultraviolet light, does not make the present invention have excellent anti-uv-ray；In addition, the new certain herbaceous plants with big flowers acid generated is due to α carbon
The steric effect of 3 alkyl on atom, so that cannot be closely aligned between its molecule, flexibility is big, can optimize the present invention
Cracking resistance energy.
