Preparation method of artificial stone with imitated wood grain pattern and artificial stone

Abstract

The invention discloses a preparation method of artificial stone with imitated wood grain pattern, which comprises the following steps: (1) preparing artificial stone mud materials with at least two different colors, and respectively stirring uniformly; (2) carrying out the following operations in vacuum state: i, conveying the artificial stone mud material with one color in step (1) to a tablet machine, and pressing the mud material into mud tablets by using the tablet machine; laying the artificial stone mud material with another color on the mud tablets, and pressing with the tablet machine; repeatedly laying and pressing the rest of the artificial stone mud materials by using the same method to obtain a wood grain unit mud material lamella; ii, overlapping the mud material layers, molding and pressing to obtain the artificial stone blocks; (3) curing the artificial stone blocks obtained in step ii, and cutting the artificial stone blocks in the direction capable of displaying the laminated grain structure, thereby obtaining the blank pieces; and (4) sanding and polishing the blank pieces in step (3) to obtain the artificial stone product. The product of the invention presents an imitated wood grain pattern.

Description

technical field [0001] The invention relates to the technical field of artificial stone production, in particular to a method for preparing artificial stone imitating wood grain patterns, and also relates to the artificial stone prepared by the method. Background technique [0002] Artificial stone is usually made of natural stone fragments, bonded by a resin composition containing initiators and accelerators, and then vibrated and compacted under vacuum to form a decorative blank (block, plate). After cutting, milling, polishing and other procedures, artificial stone blanks (blocks, plates) are finally made into artificial stone products such as various decorative plates and special-shaped materials. Artificial stone is a new type of stone that has developed rapidly in recent years. It has both the natural and firm texture of marble, the smoothness and fineness of ceramics, and the ease of processing of wood. It can be widely used in floors, walls, The decoration of the co...

Problems solved by technology

[0005] As a previous example, there is a Chinese invention patent application "a method for making wood-grain artificial stone wall and floor tiles" (application number is 200710151126.9). The traditional stirring method is used to place various raw materials for artificial stone production in a stirring device. Stirring, so that the final imitation wood grain pattern artificial stone will inevitably produce technical defects and deficiencies such as not fine enough texture, short texture and messy texture

In addition, this invention is mainly used for small-scale production of wood-grain artificial stone. This production method has low production efficiency and is difficult to meet the needs of large-scale mass production.
