Problems solved by technology

[0004] At present, the surface layer color paste composition used for artificial stone has poor water retention, suspension and stability, which greatly reduces the aesthetics, practicality and service life of artificial stone, and cannot meet the requirements of architectural decoration on artificial stone. Product Requirements for Stone Surface Color Paste Composition
[0005] In the production process of the existing artificial stone surface layer color paste composition, pigments and other components are prone to precipitation, segregation, bleeding, etc., which reduces the qualified rate of the product and its production efficiency, and increases the production cost. It is not conducive to the extensive production and application of artificial stone

Abstract

The invention provides an artificial stone block surface course mill base composition and a production method and an application thereof. The component of the artificial stone block surface course mill base composition comprises modified attapulgite, an inorganic bond material and an organic addition agent. The method for preparing the composition comprising the following steps: modifying the attapulgite by utilizing a silane coupling agent and a quaternary ammonium salt cationic surface active agent so as to obtain the modified attapulgite; mixing the modified attapulgite, a pigment, a cement and other addition agents for dispersing and hybridizing; and adding silica sand in the prepared sizing agent, and stirring and mixing to obtain a modified attapulgite artificial stone block surface course mill base. The surface course mill base composition obtained by adopting the composition and the production method has high water-retaining property, suspension property, stability, rheological property and thixotropy, the sediment, dissociation and bleeding problems in a production operation process of the artificial stone block surface course mill base composition can be reduced, and the thickness of the surface course mill base sprayed on the concave-convex surfaces of an irregular artificial stone block mould is uniform and consistent.

Description

technical field [0001] The invention relates to an artificial stone surface layer color paste, in particular to a modified attapulgite clay artificial stone surface layer color paste composition and its production method and application. Background technique [0002] Artificial stone is made of inorganic powder and an appropriate amount of binder, flame retardant, color, etc., and is formed and solidified by mixing ingredients, porcelain casting, vibration compression, extrusion, etc. According to the raw materials, it can be roughly divided into: resin type , composite type, cement type and sintered type. Compared with natural stone, artificial stone has bright colors, high smoothness, uniform color, compression and wear resistance, good toughness, compact structure, strong and durable, light specific gravity, non-absorbent, corrosion and weathering resistance, small color difference, no fading, radioactive low merit. With the improvement of people's living standards, the...
