Abstract

The present invention discloses a method for preparing alumino-silicate based mineral polymeric material. The invention takes alumino-silicate as solid constituent, and alkaline mixed liquor as liquid constituent, which serves as an excitant of the mineral polyreaction. A physical stirring method is applied to mix the liquid constituent and the solid constituent, after pressure moulding, mineral polymeric material is obtained. The method has the following characteristics: cheap raw material, simple equipment and technology, being mouldable under room temperature; the mineral polymeric material prepared by the invention has a certain strength and toughness; the technology used by the invention makes the performance of the mineral polymeric material is easy to get further improvement by addition, such as strengthen, toughen and improve tribology performance and so on.

Description

Technical field: [0001] The invention relates to a method for preparing an aluminosilicate mineral polymer material. Background technique: [0002] Using common clay-based aluminosilicate raw materials at relatively low temperatures to prepare mineral polymer materials with chemical activators has broad application prospects. There have been related patent reports abroad (US patent 4,349,386, US patent 4,472,199). The raw materials for the preparation of this material are mostly kaolin, but the performance of kaolin obtained from different origins and different processing methods varies greatly, which obviously affects the performance of the material. In addition, the preparation raw materials of this material can be extended to industrial waste such as fly ash and slag, which has practical value in waste utilization; there has been some progress at home and abroad to seal nuclear waste and toxic metal ions with mineral polymer materials. ; Specially enhanced mineral polyme...
