The ecological stone product prepared in the embodiment 1-3 has no obvious pore and crack defects on the surface of the inorganic ecological stone, high surface density, good dampproof effect when placed in a humid environment, difficult water absorption, high hardness, good wear resistance and waterproof performance, high glossiness and difficult scratch generation; in the embodiment 1-3, firstly, the moisture in the inorganic ecological stone is removed through heating, meanwhile, the gas on the inner wall of the inorganic ecological stone is expanded and overflows, the filling treatment liquid is permeated into the particle holes when being coated, and as the inorganic ecological stone is cooled, the inner gas is cooled and contracted, the filling treatment liquid coated on the surface of the inorganic ecological stone is sucked, fully filled and adhered after solidification, so that the integral hardness of the inorganic ecological stone is increased, the inorganic ecological stone is not easy to wear and break, and on the other hand, the silicon phosphate is added into the filling treatment liquid to accelerate the solidification speed of sodium silicate and simultaneously react with alkaline metal ions in the silicon phosphate, so that the water absorption of the inorganic ecological stone is reduced, and the particles on the inorganic ecological stone are not easy to fall in the subsequent glaze sealing operation, so that the glaze sealing operation is better.
Comparative example 1: the procedure and conditions were substantially the same as in example 2, except that step S2 was omitted in the process for preparing inorganic ecological stone of example 2.
As is clear from comparative example 1, the ecological stone product prepared in comparative example 1 has many fine particle holes of the mildly hemp, and the ecological stone molded body is easy to generate broken particles in the glaze sealing step due to the fact that the treatment liquid is filled into the small particle holes after the pressing in comparative example 1, so that the glaze sealing quality is seriously affected, the wear resistance of the ecological stone molded body is not good, and meanwhile, the moisture resistance of the ecological stone molded body is general due to the fact that the ecological stone molded body is not protected by the filling treatment liquid.
Comparative example 2: the procedure and conditions for the preparation of the inorganic ecological stone of example 2 are substantially the same as those of example 2, except that step S3 is absent.
As is clear from comparative example 2, the ecological stone product prepared in comparative example 2 has only the filling treatment liquid subjected to polishing, has certain glossiness, waterproof performance and hardness, but has low wear resistance, and is easy to lose glossiness and generate scratches after long-time friction, so that dust and the like remain, and the ecological stone product is inconvenient to clean.
Comparative example 3: the steps and conditions of the preparation process of the inorganic ecological stone are basically the same as those of the embodiment 2, except that the silicon phosphate as a curing agent is not added to the filling treatment liquid in the step S2.
As is clear from comparative example 3, the surface flatness and abrasion resistance of the eco-stone product prepared in comparative example 3 are good, but the efficiency of inorganic eco-stone processing is reduced due to the absence of the curing agent when the inorganic eco-stone is filled with the filling treatment liquid, and the inorganic eco-stone needs to be heated and cured for a long time to be heated again, so that the filling treatment liquid in the pore diameter is extruded, the adhesion strength between the inorganic eco-stones is reduced, and the overall hardness is reduced.
Comparative example 4: the steps and conditions of the preparation process of the inorganic ecological stone are basically the same as those of the embodiment 2, except that the curing agent silicon phosphate in the filling treatment liquid in the step S2 is replaced by a common curing agent sodium fluosilicate.
As is clear from comparative example 4, the surface smoothness and hardness of the eco-stone product prepared in comparative example 4 are good, but since the curing agent in the filling treatment liquid is sodium fluosilicate, the curing can be accelerated and the inorganic eco-stone product has a certain hardness when being filled, but alkali metal ions or oxides are easy to generate after the inorganic eco-stone product reacts with sodium silicate, and the water absorption performance is present, so that the overall moisture resistance of the inorganic eco-stone product is reduced, and the overall service life is easy to be reduced when the inorganic eco-stone product is used for a long time and is in a humid environment.
