(2) above-mentioned BMC is transported to the thickening chamber, thickening is 24 hours under 40-50 ℃ of temperature, and thickening at room temperature is 24 hours again, promptly gets moldable BMC.
(3) mold pressing: add the good moulding compound of a certain amount of thickening in the mould of preheating; Through pressurization, heating after fixing moulding, idiographic flow is reinforced (the solid molded material being added in the steel die of preheating) → matched moulds → fill mould (moulding compound is in the pressure current downflow and be full of whole die cavity) → curings (fully curing after the pressure and temperature of setting keeps certain hour down) → die sinking taking-up goods.
The area that feeds intake during the compression moulding of present embodiment BMC is 80% of a finished product frontal projected area, and pressure is 7MPa, and the temperature of mould pros and cons is respectively 145 degrees centigrade and 136 degrees centigrade.Solidified forming time is 180 seconds.After this product compression moulding, the surface processing of will polishing promptly gets integral bathroom and uses the high abrasion product.
The wear-resisting effect of the finished surface that present embodiment obtained is fine, because the content of fine aluminum hydroxide powder is high in the resin paste, causes resin paste viscosity also high, and must adding more, ZR 200 dilutes.Because the cost of fine aluminum hydroxide powder is low than resin, therefore with embodiment 1, embodiment 2 compares, and the manufacturing cost of embodiment 3 descends significantly.After the thickening again thickening at room temperature make product performance further improve after 24 hours.
In sum, when BMC is produced, pay special attention to following some:
1) thickening material will could add after unsaturated polyester resin, low shrinkage additive, initiator and inner pattern releasing agent applicable add kneader, in order to avoid whole resin paste viscosity increases and can't operate.
2) strongthener will slowly add kneader, in order to avoid mix uneven.
3) the kneading time can not be long, in order to avoid fibre-tendering causes product strength to descend significantly.
More than disclosedly be merely several specific embodiment of the present invention, but the present invention is not limited thereto, any those skilled in the art can think variation, all should drop in protection scope of the present invention.
