Hollow insulated sound-proof plate and its manufacturing method

This invention discloses one kind of hollow heat preservation soundproofing board and it's manufacture method, which has the characters that hollow heat preservation soundproofing board cost is inexpensive, and utilization of waste or environmental protection, has good heat preservation, sound insulated and anti- burns. Heat preservation and sound insulated can threads at will and its craft is simple, quality is steady. The manufacture method of the invention is that group the inner-core matrix surface-side molding and the end surface molding 13to the inner-core frame: Fill the material slurry in the inside cavity of the frame up to the bottom of the end-surface orientation hole; the material slurry is the mixture of the smashed main body material and bond; the main body material can be the perlite, straw, straw stalk or every other cheap material has the heat preservation and sound insulated functions, the bond is compounded according to the proportion of the phosphor gesso or concrete light-burn-powder or sodium chloride compound liquid, and mixed and milled with the fore mentioned main body material. Spread the slurry material flat, and make the orientation core thread the orientation hole of the end-surface molding, and then put the thread hole-type core in turn, put in the board surface connection hole-type core, at last fill the material slurry in the frame; after the solidify, unload the long-margin molding, end-surface molding and the board surface connection hole-type core, after the slat solidified and shaped, take the orientation core out first, and then take out the two sides thread hole-type core, at last take the thread hole-type core out at the orientation of the modeless rack, and clearing up.
