Geopolymer crack-resisting artificial stone and preparation method thereof

Abstract

The invention relates to an artificial stone and a preparation method thereof, in particular to a geopolymer crack-resisting artificial stone and a preparation method thereof. The geopolymer crack-resisting artificial stone is prepared from the following raw material components in parts by weight: 100 parts of nickel iron slag, 35 to 50 parts of a geopolymer, 7 to 15 parts of water, 0.35 to 1.0 part of a water reducing agent, 0.07 to 0.1 part of a plasticizer, 0.7 to 1.5 parts of an anti-cracking agent and 0.01 to 2 parts of pigment. The preparation method of the geopolymer crack-resisting artificial stone comprises the following steps: firstly, stirring and mixing raw materials; secondly, carrying out compression moulding; thirdly, curing; fourthly, polishing. The geopolymer crack-resisting artificial stone disclosed by the invention has the advantages of better acid and alkali resistance characteristics, capability of being used outdoors, good weather resistance and relatively high breaking strength; the preparation method of the geopolymer crack-resisting artificial stone disclosed by the invention adopts simple process steps and strictly controls process parameters of all the steps, so that the final quality of a finished artificial stone product is ensured.

Description

technical field [0001] The invention relates to an artificial stone and a preparation method thereof, in particular to a geopolymer anti-crack artificial stone and a preparation method thereof. Background technique [0002] At present, the preparation method of artificial stone mainly uses natural ore particles as aggregate, resin or inorganic bonding material as binder, and is formed by vacuum vibration pressing. It is a building decoration material with rich colors and good mechanical properties. [0003] However, the artificial stone with resin as the binding material is easy to age and has poor weather resistance, so the product cannot be used outdoors. For example: the application number is 201710890790.9, and the Chinese invention patent named "An artificial quartz stone plate"; the application number is 201410629239.5, the Chinese invention patent titled "An Artificial Stone and Its Preparation Method"; and the Chinese invention patent titled "A Formula of Artificial ...

Problems solved by technology

[0003] However, the artificial stone with resin as the binding material is easy to age and has poor weather resistance, so the product cannot be used outdoors. For example: the application number is 201710890790.9, and the Chinese invention patent titled "A Kind of Artificial Quartz Stone Plate"; the application number is 201410629239.5, the Chinese invention patent titled "An Artificial Stone and Its Preparation Method"; and the Chinese invention patent titled "A Formula of Artificial Quartz Stone" with the application number 201510846486.5

[0004] In addition, artificial stone with cement as the binding material has good weather resistance, but the product has poor acid resistance and is susceptible to corrosion under acidic conditions for a long time. The Chinese invention patent of "Artificial Stone Production Process"; and, the application number is 201610167670.1, the Chinese invention patent titled "An Environmentally Friendly Artificial Stone Manufacturing Process"
