The invention discloses a method for synthesizing organic
silicon, in particular provides a method for preparing methyl phenyl
silicone resin which has low curing temperature by self and is not sticky repeatedly. The invention uses the monomers of methyl
trichlorosilane, dimethyldichlorosilance, phenyl
trichlorosilane, dichloromethylphenylsilane, diphenyl
dichlorosilane and the like to obtain a methyl phenyl
silicone resin with low curing temperature and a paint film which is not sticky repeatedly after being cured by the processes of adjusting the proportion of raw materials, controlling proper
reaction temperature and
polymerization time, carrying out
hydrolysis reaction and
polycondensation reaction, etc. The invention has the advantages that the methyl phenyl
silicone resin prepared by the method has the characteristics of low curing temperature, being not sticky repeatedly, being clear and transparent, high and low
temperature resistance,
weather resistance, being insulating and the like; the methyl phenyl
silicone resin is in particular fit for dip
varnish higher than grade H; and the methyl phenyl
silicone resin is used for confecting insulated paint, weather-resistant paint and
heat resistant paint higher than grade H, is used for
heat resistant parting agent and also can be used in the fields with rigorous using requirements, such as
heat resistant water blocking and sand prevention for
oil drilling, etc.
