Problems solved by technology

Due to the large difference in performance between inorganic materials and organic polymer materials, the use of existing artificial stone composition components to make composite artificial stone with high stability, high strength, and high crack resistance requires relatively high polymerization conditions and polymerization reaction time. Leading to problems such as long production cycle of composite artificial stone, increased production cost, and poor product performance

Abstract

The invention provides a modified attapulgite clay composite artificial stone material and a production method thereof. The stone material is produced from a component, namely, modified attapulgite clay, by using a method comprising the following steps: modifying high-viscosity attapulgite clay by using a silane coupling agent, and mixing the modified attapulgite clay with structure slurry so as to obtain modified attapulgite clay composite structure slurry; preparing a color slurry material, a surface layer slurry material and a middle layer slurry material; and sufficiently spraying the surface layer slurry material on the surface of a mold to be colored according to a color ratio, after the coloring is accomplished, uniformly spraying the middle slurry layer on the surface of a surface color layer, further casting the modified attapulgite clay composite structure slurry inside the mold, and shaping, steaming, cultivating and maintaining so as to obtain the composite artificial stone material. The artificial stone material has good stability, strength, crack resistance and saltpetering resistance, and moreover the production period of the artificial stone material is shortened, the production efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to an artificial stone, in particular to a modified attapulgite clay composite artificial stone and a production method thereof. Background technique [0002] With the improvement of people's living standards, the demand for building stone is increasing. Artificial stone is widely used in commercial, residential, and even military fields because of its easy-to-obtain raw materials, controllable components, diverse color patterns, environmental protection and energy saving. . The production of artificial stone slurry can generally be divided into structural slurry, color slurry, surface layer slurry and isolation middle layer slurry. Among them, structural slurry (also known as matrix slurry) has the greatest influence on the performance of artificial stone. [0003] At present, the composite artificial stone structure slurry in artificial stone mainly includes inorganic materials, organic polymer materials and additives. The pr...
