Abstract

The invention provides a hydroxyl acrylic ester emulsion for artificial stone manufacturing, a preparation method and artificial stone manufactured by the hydroxyl acrylic ester emulsion. The hydroxyl acrylic ester emulsion comprises the following substances: a mixed monomer 1, a mixed monomer 2, polymer polyol, an emulsifier, an initiator and water. The preparation of the hydroxyl acrylic ester emulsion adopts two steps: multiple chemical structure units are introduced for copolymerization, and the polymer polyol is added in the reaction process, so that the compressive strength, the bending strength and the hardness of artificial stone are further improved. Meanwhile, hydroxyl in the hydroxyl acrylic ester emulsion can be cross-linked with silicate in packing for manufacturing the artificial stone, the manufactured artificial stone ingredients are better in scattered fineness, the structure is more compact and uniform, and the various strengths and the glossiness of the manufactured artificial stone are better.

Description

technical field [0001] The invention belongs to the field of new materials, in particular to a hydroxyacrylate emulsion for making artificial stones, a preparation method thereof and the prepared water-based artificial stones. Background technique [0002] The production of artificial stone currently mainly uses unsaturated polyester resin or acrylic resin (polymethyl methacrylate) as the binder. Due to the use of styrene solvent in the manufacturing process of unsaturated polyester resin, a large amount of styrene will be volatilized during the processing and production process, and the artificial stone made will release residual styrene solvent. Due to the large curing shrinkage rate of unsaturated polyester, the processing and setting properties are not good, the heat distortion temperature is 50~60 ℃, and the heat resistance and flame retardancy are not ideal. At the same time, because it contains a large amount of benzene rings and double bonds that remain unreacted, i...
