Abstract

The invention discloses a water-resistant styrene-free artificial stone resin, which comprises, in parts by weight: 20-40 parts of glycol, 30-45 parts of organic acid, organic acid anhydride or a mixture thereof, 0.01-0.1 part of catalyst, 0.01-0.05 part of barrier Polymerizing agent, 0.05-0.5 part of paraffin, 15-27 parts of tertiary carbon glycidyl ester, 3-8 parts of cross-linking functional monomer, the organic acid, organic acid anhydride or its mixture contains unsaturated organic acid and / or organic acid anhydride . The invention also discloses a preparation method of water-resistant styrene-free artificial stone resin, which includes preparing an unsaturated polyester prepolymer for use; mixing tertiary carbon glycidyl ester, cross-linking functional monomer, and p-toluenesulfonic acid with the first The polyester prepolymer in the reactor is mixed and reacted and then discharged. The water-resistant styrene-free artificial stone resin of the present application has low VOC content and has good water resistance; the preparation method of the water-resistant styrene-free artificial stone resin of the present application has the advantages of simple process and less pollution.

Description

technical field [0001] The invention relates to the field of artificial stone, in particular to a water-resistant styrene-free artificial stone resin and a preparation method thereof. Background technique [0002] Artificial stone usually refers to artificial stone solid surface material, artificial stone quartz stone, artificial stone granite and so on. Artificial stone resin is usually composed of matrix resin and diluent solvent. The matrix resin of unsaturated polyester resin can be conventional unsaturated polyester with dibasic alcohol and dibasic acid as the main raw material; the conventional diluent is styrene monomer. The publication number is CN108047433A, and the name is a Chinese patent application for unsaturated resin used in artificial stone. The raw materials for preparing modified unsaturated resin include maleic anhydride and tetrahydrophthalic anhydride as acid raw materials; Propylene glycol, diethylene glycol and neopentyl glycol; also include styrene ...
