(A) 5 to 30 parts by weight of at least one of alkali metal compound of lithium, sodium and potassium calculated as the formula M.sub.2 O where M is an alkali metal; (B) 0.2 to 10 parts by weight of a perchloric acid radical in the form of the acid or a salt or amine thereof, calculated as perchloric acid radical; and (C) 1 to 50 parts by weight of a hydrophobic dispersing agent having a boiling point or a decomposition temperature of 200.degree. C. or higher. All the parts by weight are based on 100 parts by weight of antimony pentoxide (Sb.sub.2 O.sub.5). The flame retardant of the present invention does not impair transparency of the halogen-containing vinyl resin, and also does not worsen various physical properties such as thermal stability and weathering resistance. The invention also provides (1) flame retardant halogen containing resins and (2) a process for preparing the powdered flame retardant.

    摘要: An apparatus for laminating plates having guide holes for aligning each plate to a predetermined position. A horizontal base is provided for stacking the plates thereon. A conveyor device conveys the plates to a predetermined position over the horizontal base one by one, the conveyor device dropping the plates on the horizontal base from the predetermined position so as to laminate the plates to each other. A guide device including guide pins which are disposed perpendicular to the conveyed plate at the predetermined position above the conveying device, the guide pins moving together with the falling plate to engage in the guide holes, respectively, to align each of the plates along the guide pins while laminating the plate on the horizontal base, and to return the guide pins to the initial position thereof.
