Abstract

The invention discloses a polyurethane adhesive composition for a lawn backing adhesive. An artificial lawn using the polyurethane adhesive is characterized in that the pull-out force shown at the bottom back is greater than 40 N, and the cost is low. The polyurethane adhesive composition for the artificial lawn backing adhesive is prepared from the following components in parts by weight: 100 parts of polyhydric alcohol, 15 to 30 parts of chain extender, 0.1 to 5 parts of catalyst, 0.5 to 2.5 parts of thixotropic agent, 100 to 300 parts of filler, and 5 to 110 parts of organic polyisocyanate.

Description

technical field [0001] The invention relates to an adhesive composition, in particular to a polyurethane adhesive composition for lawn back glue. Background technique [0002] In recent years, artificial turf has developed vigorously. In the production process of artificial turf, the main process is to tuft the grass silk to the main back through tufting machine weaving, wherein a single grass thread passes through the main back and is attached to the main back. This primary backing is usually a natural or synthetic fiber material such as ephedra or polypropylene. The grass silk and the main back cannot be tightly connected by tufting, and it is easy to be pulled out from the main back. The necessary anchoring is obtained by applying a layer of free-flowing adhesive to the primary backing of the artificial turf. This anchoring capability is usually expressed in terms of pull-out force or pull-off force. Another important physical property of artificial turf is dimensiona...
