Abstract

The invention discloses an acrylic artificial stone. The acrylic artificial stone comprises the following components in parts by weight: 40-70 parts of acrylic resin monomers, 10-25 parts of a thickening agent, 200-350 parts of inorganic fillers, 0.01-2 parts of a curing agent and 0-2 parts of an accelerant. The manufacturing method of the pure acrylic artificial stone comprises the following steps: A, preparing the thickening agent; B, kneading; and C, forming. Compared with the prior art, the pure acrylic artificial stone disclosed by the invention has the advantage that thickening performance and storage stability are excellent by mixing the special thickening agent and monomers in the invention; the acrylic artificial stone made of acrylic molding plastics has excellent appearance and performance, and can be used for an industrial purpose.

Description

technical field [0001] The invention relates to a pure acrylic artificial stone and a manufacturing method thereof. Background technique [0002] Molded acrylic artificial stone is prepared by mixing inorganic fillers such as aluminum hydroxide into acrylic resin, this acrylic artificial stone has various excellent functions and properties such as excellent appearance, soft touch, weather resistance and molded products. Other properties, and widely used in countertops such as kitchen counters, laundry and dressing table, waterproof surface and other construction purposes. But the boiling point of acrylic resin is low, which limits its application. [0003] The existing foreign acrylic artificial stone has excellent heat resistance and flexibility, but its molding time is very slow, the production efficiency is low, and the surface effect is not good. At the same time, the existing acrylic artificial stone has excellent performance and appearance, but the preparation proces...
