Problems solved by technology

When the emulsion is applied to the artificial turf adhesive, the precipitation of the emulsifier will cause a weak boundary layer to form between the adhesive film and the grass silk, thus affecting the adhesion and water resistance of the adhesive layer
In response to this problem, the Chinese patent with the publication number CN103374090A once disclosed a method for preparing carboxylated styrene-butadiene emulsion for artificial turf back coating by soap-free emulsion polymerization. This method improves the adhesive force of the glue layer to a certain extent, but the improvement is limited. At the same time, the emulsion prepared by soap-free emulsion polymerization has poor stability and low solid content, which greatly limits its industrial application
[0005] In the prior art, carboxylated styrene-butadiene emulsion has a certain bonding strength, but the water resistance is generally poor; the improvement of the bonding strength and water resistance starts with a single performance, and has a certain effect, but when it is applied to mechanical These improved emulsions are still far from satisfactory results in improving the bonding strength and water resistance for sports artificial turf with higher performance requirements

Abstract

The invention discloses a high-performance carboxylic styrene-butadiene emulsion for artificial turf, and the bottom back of the artificial turf with the high-performance carboxylic styrene-butadieneemulsion for the artificial turf has excellent bonding strength and water resistance. The high-performance carboxylic styrene-butadiene emulsion for artificial turf is prepared from monomers, an emulsifier, other auxiliary agents and water, wherein the monomers used in the preparation consist of a main monomer, an unsaturated carboxylic acid monomer and a modified monomer, the modified monomer isa mixed modified monomer containing an unsaturated silane-type monomer and a multi-double bond type monomer, and the mixed modified monomer content is 0.2-10 wt% of the total monomer content. According to the high-performance carboxylic styrene-butadiene emulsion for artificial turf, groups which can be cross-linked in a curing stage can be introduced through the modified monomer, so that the compactness of an adhesive film is increased, the stress defect of an adhesive layer is reduced, and then the mechanical properties and water resistance of the adhesive layer can be improved; and a uniquesilicone structure can be introduced into the polymer through the unsaturated silane-type monomer, thereby providing more hydrophobic characteristics to the adhesive layer, and further improving thewater resistance.

Description

Technical field [0001] The invention relates to a styrene-butadiene emulsion, more specifically to a high-performance carboxyl styrene-butadiene emulsion for artificial lawns. Background technique [0002] Artificial turf was born in the United States in the 1960s, and after half a century of development, it has become more and more accepted by people. In the production process of artificial turf, it is necessary to apply a layer of adhesive on the back to fix the grass. The currently commonly used adhesive is an environmentally friendly water-based adhesive. This water-based adhesive is composed of emulsion, filler and additives. Partial composition. The emulsion can be pure acrylic emulsion, styrene-acrylic emulsion, styrene-butadiene emulsion, carboxylated styrene-butadiene emulsion, polyvinyl acetate emulsion, etc., and carboxylated styrene-butadiene emulsion is favored for its high bonding strength and good stability. However, when the carboxyl styrene butadiene emulsion c...
