Preparation method of artificial stone with marble-imitated Sha Anna high-grade variety pattern and artificial stone prepared thereby

Abstract

The invention discloses a preparation method of an artificial stone with a marble-imitated Sha Anna high-grade variety pattern, which comprises the following steps of: (1) preparing artificial stone pug in a stirring way; (2) vacuumizing to be more than -0.077MPa to perform the following steps of: 1. prefabricating and tabletting the artificial stone pug; 2. spraying color paste to the surfaces of the prefabricated and tabletted pug pieces; 3. accumulating and overlapping the cloth of the pug pieces; and 4. pressing in a forming way; and (3) solidifying a pressed forming body under the normal temperature. As the step of prefabricating and tabletting is increased before the step of spraying the color paste, the streak of the pattern on the surface of the marble-imitated Sha Anna high-grade variety artificial stone prepared by the method is thinner and longer, has a certain trend regularity, and avoids the coarse streak and the unordered trend of the product which is correspondingly prepared by existing working procedures without the step of tabletting, thereby more realistically reappearing the delicate grain of the marble Sha Anna high-grade variety and bringing greater upvaluation space to the product.

Description

technical field [0001] The invention relates to a decorative material, in particular to an artificial stone imitating a high-grade pattern of marble Saana, and to a preparation method of the artificial stone. Background technique [0002] Artificial stone is usually a decorative blank (block, plate) material that is made of natural stone fragments, bonded with a resin composition containing an initiator and an accelerator, and then vacuum-pumped and vibrated. After cutting, milling, polishing, etc., the billets (blocks, plates) of artificial stone are finally made into various decorative plates and profiled materials. Artificial stone is a new type of stone that has developed rapidly in recent years. It has both the natural texture and solid texture of marble, the smoothness and fineness of ceramics, and the ease of processing wood. It can be widely used in the floors, walls, and walls of various buildings. The decoration of the countertop has broad development prospects in...

Problems solved by technology

Therefore, compared with the natural Saana marble, the above two spraying methods still have two obvious disadvantages: one is that the artificial stone mud (or base material) subjected to spraying in the process contains agglomerates. The block is only formed by stirring, and its texture is loose and its edges are rough. As a result, the color paste can penetrate deep and spread to a certain extent after spraying, resulting in the corresponding color paste boundary formed on the product board surface. The lines are always on the blurred side; the second is that the way the clumps pile up on top of each other is not at all controlled, so the coloring around the clumps tends to be meshed and the texture is completely disordered
