AI Technical Summary

Problems solved by technology

[0004] Resin-type artificial stone is greatly limited in its application fields because the cementing material used is organic resin. For example, the resin is easily aged and brittle under strong ultraviolet radiation, so it cannot be used outdoors; the resin is easily deformed under high temperature conditions, so it cannot be used. In places such as stoves with high temperature; in addition, the artificial stone products are more expensive due to the high cost of resin, which also greatly limits the consumer groups of artificial stone products

Abstract

The invention discloses soil gathering gelled material used for preparing man-made stones. The soil gathering galled material is made by orderly adding the materials below into a stirrer with the weight share and stirring to produce the plasm body, wherein, the materials include: 30 to 40 weight parts of metakaolins, 30 to 55 weight parts of water glasses, 2 to 10 weight parts of alkali metals hydrates and 0.1 to 15 weight parts of water. The man-made stone produced by the soil gathering gelled material has the advantages of good dynamo capacity and excellent enduring capacity and resistance to elements. Besides, the cost is much lower and the invention is much applicable to large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of building materials for decoration, in particular to an earth-polymer cementitious material used for preparing artificial stones. Background technique [0002] Artificial stone or man-made synthetic stone is essentially concrete used in the decorative field. When resin is used as an adhesive and is rich in decorative effect of crushed stone aggregate, it is decorative resin concrete. [0003] At present, the popular artificial stone products on the market generally use resin, especially unsaturated polyester materials as adhesives, so they are classified as resin-type artificial stone. [0004] Resin-type artificial stone is greatly limited in its application fields because the cementing material used is organic resin. For example, the resin is easily aged and brittle under strong ultraviolet radiation, so it cannot be used outdoors; the resin is easily deformed under high temperature conditions, so it ca...
