Abstract

The invention discloses water-resistant styrene-free artificial stone resin. The artificial stone resin includes the following components in parts by weight: 20 to 40 parts of a diol, 30 to 45 parts of an organic acid, an organic acid anhydride or a mixture of the organic acid and the organic acid anhydride, 0.01 to 0.1 part of a catalyst, 0.01 to 0.05 part of a polymerization inhibitor, 0.05 to 0.5 part of paraffin, 15 to 27 parts of glycidyl neodecanoate, and 3 to 8 parts of a cross-linking functional monomer, wherein the organic acid, the organic acid anhydride or the mixture of the organicacid and the organic acid anhydride contains an unsaturated organic acid and / or an organic acid anhydride. The invention also discloses a preparation method of the water-resistant styrene-free artificial stone resin. The method comprises the steps of preparing an unsaturated polyester prepolymer for standby application; mixing the glycidyl neodecanoate, the cross-linking functional monomer and p-toluenesulfonic acid for a reaction, mixing the reaction product and the polyester prepolymer in a reaction kettle for a reaction, and performing discharge. The water-resistant styrene-free artificialstone resin provided by the present application has a low VOC content and better water resistance; and the preparation method of the water-resistant styrene-free artificial stone resin has the advantages of simple procedures and little 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 ...
