Abstract

The invention relates to amine resin modified carboxylic butadiene-styrene copolymer latex, wherein amine resin and a carboxylic butadiene-styrene copolymer in an amine resin modified carboxylic butadiene-styrene copolymer are connected through covalent bonds; the amine resin contains N-hydroxymethyl and / or N-methylene alkyl ether functional groups. The invention also relates to a method for preparing the latex, and a purpose of the amine resin modified carboxylic butadiene-styrene copolymer latex as a bonding agent in carpet production, artificial grass manufacturing, building waterproofing,papermaking and reconstituted leather manufacturing.

Description

technical field [0001] The invention relates to an amino resin modified carboxylated styrene-butadiene copolymer latex and a preparation method thereof. The present invention also relates to the use of the amino resin-modified carboxylated styrene-butadiene copolymer latex as an adhesive in carpet production, artificial turf production, building waterproofing, papermaking and regenerated leather. Background technique [0002] With the development of technology, synthetic latex has gradually replaced natural latex as an adhesive, and has been widely used in shoe materials, carpets, recycled leather, artificial turf and other fields, especially carboxylated styrene-butadiene latex has become a mainstream products. The introduction of carboxyl groups into styrene-butadiene latex through the copolymerization reaction of unsaturated carboxylic acid monomers can effectively improve its adhesive strength, and the raw materials of carboxylated styrene-butadiene latex are easy to ob...
