The present invention utilizes the discarded perlite powder of the solid of pearlstone process of manufacture and the micro-powder of pearlstone and a small amount of plastic raw material under 950 ~ 1050 DEG C of very low temperature working conditions, the thermal conductivity produced is less than 0.08W/ (m k), water-intake rate is less than 0.5%, folding strength is greater than 3.5MPa, External Exposure Index lower than 0.8, Outreach services lower than 1.3, fire resistance rating is A1 level, thickness 30 ~ 60mm, has insulation and the ceramic of decoration. Therefore the insulation and decoration finishing of indoor and outdoor, public situation or family room can be widely used in.
Upper embodiment only describes the preferred embodiment of the present invention, in order to the technical scheme of the present invention to be described and unrestricted, but several details being not limited in above-mentioned enforcement mode, within the objective and principle of the present invention, combine by any suitable mode, in order to avoid unnecessary repetition, illustrate no longer separately. In addition, the combination between the various different enforcement mode of the present invention, as long as not running counter to the thought of this invention, is considered as the content disclosed in this invention equally.
