6. a preparation method for unsaturated polyester glass fiber cloth laminated board, under is characterized in that including Row step:

A, preparation resin paste: by styrene solution, 30～60 of 162 weight portion unsaturated polyester resins Weight portion percentage by weight is the styrene solution of saturation type polyester resin, 20～50 weight portion of 70% Percentage by weight is the styrene solution of the polyvinyl acetate of 40%, 280～360 weight portion hydroxides The parts by weight of activated magnesia in aluminium, 2～4,2～3 weight portion initiators, 10～20 weight portion pigment paste, And 10～15 weight portion zinc stearate weight and raw material composition take each component raw material and throw Enter in blending tank, stirring mixing 8～12 minutes, be i.e. configured to resin paste；

Described pigment paste be weight ratio be pigment and the described percentage by weight of 10～50:50 be 65%～ 68% can the metaphenylene of thickening or the blended grinding of styrene solution of adjacent benzene-type unsaturated polyester resin Mixture；Described pigment be the one in titanium dioxide, carbon black, iron oxide red, phthalocyanine blue or Two or more mixtures；

B, prepare unsaturated polyester glass fiber cloth prepreg: by resin paste by speed be 6～ The coating machine of 7m/min is evenly coated in two carrying film strips, and forming one side has the of resin paste film layer One carrying film strips and one side have the second carrying film strips of resin paste film layer, more coated machine roll is by first The resin paste film layer of carrying film strips and the one side of glass fabric fit together, by the second carrying film strips The resin paste film layer another side relative with glass fabric fit together, then rolling, put into Cure 15～17h between the curing that constant temperature is 40 DEG C, i.e. prepare unsaturated polyester glass fiber cloth prepreg；

C, hot pressing are for unsaturated polyester glass fiber cloth laminated board: by unsaturated polyester glass fiber cloth Prepreg is cut into product required size and removes the carrying film strips of laminating on its two sides, needed for product More than one layer unsaturated polyester glass fiber cloth prepreg overlap is layed in 140～150 DEG C by thickness In mould, through hot-forming, hot pressing technique is: control temperature 140～150 DEG C, control pressure 10～12MPa, temperature retention time is that to be molded the temperature retention time of every mm of thickness product be 40～60 seconds, i.e. 40～60sec/mm, hot pressing is taken out after terminating, and through naturally cooling to room temperature, i.e. prepares unsaturated polyester (UP) Fiberglass cloth laminate product.
