Carboxylic butadiene-styrene latex as well as preparation method and application thereof

The invention relates to the technical field of styrene-butadiene latex synthesis, in particular to carboxylic styrene-butadiene latex and a preparation method thereof. On the first aspect, the carboxylic butadiene-styrene latex is prepared from the following components in parts by weight: 80 to 120 parts of deionized water, 50 to 60 parts of butadiene, 40 to 50 parts of styrene, 0 to 10 parts of polar monomer, 3 to 5 parts of crosslinking monomer, 2 to 5 parts of dicarboxyl unsaturated carboxylic acid, 0.6 to 1 part of initiator, 0.4 to 0.8 part of molecular weight regulator, 1 to 3 parts of emulsifier, 0.2 to 0.6 part of neutralizer, 0.1 to 0.5 part of defoaming agent and 0.2 to 0.8 part of antioxidant. On the second aspect, the invention further discloses a process for preparing the carboxylic butadiene-styrene latex from the raw materials. The carboxylic butadiene-styrene latex prepared by the invention is high in bonding fastness, good in washing resistance and relatively low in cost, and a fabric prepar
