Stirred after alkene-methylmethacrylate copolymer, 0.5-1 parts by weight oleamide and the mixing of 0.2-0.4 parts by weight antioxidant 1010
5-10min is mixed, is then granulated with double screw extruder melting extrusion, obtains transformer framework plastic composite.
The solid content of the VAE emulsions is 30-40%.
The particle diameter of the nano-sized magnesium hydroxide is 50-200nm.
The particle diameter of emulsion particle is 60-100nm in the styrene-butadiene latex.
The step（2）The condition of middle centrifugal spray drying is 200-220 DEG C of inlet temperature, rotor speed 20000-
25000r/min。
The temperature of the melting extrusion is 230-250 DEG C.
It is an advantage of the invention that：
VAE emulsions are first obtained modified glass-fiber by the present invention in fiberglass surfacing spraying film forming, then by magnesium hydroxide point
The suspension in water is dissipated to be well mixed with styrene-butadiene latex and be spray-dried to obtain a nanometer hydrogen using atomizer drier
Magnesia-butadiene-styrene rubber hydridization powder, finally by modified glass-fiber, nano-sized magnesium hydroxide-butadiene-styrene rubber hydridization powder and PET
It is granulated after the blending of the raw materials such as resin with double screw extruder melting extrusion, obtains transformer framework plastic composite.One side
Face, surface modification is carried out to glass fibre by VAE emulsions, improved tough with the compatibility of PET resin matrix and material
Property, on the other hand, the elasticity and anti-flammability of material are improved by introducing nano-sized magnesium hydroxide-butadiene-styrene rubber hydridization powder, so as to
Lift pressure-resistant, the vibration-resistant property of material, and noise reduction effect.Transformer framework prepared by the present invention is had concurrently with plastic composite
Excellent flame retardant performance, impact strength, it is pressure-resistant, vibration-resistant property is good, and there is good noise reduction effect, be advantageous to lift dry type
The performance and used life of transformer.
