Problems solved by technology

However, the most basic requirement of artificial turf is to have a very good pull-out force, and now the requirements are getting higher and higher. Currently used, carboxylated styrene-butadiene latex is difficult to obtain excellent pull-out force, and at the same time there will be rubber surface Cracking problem, and carboxylated styrene-butadiene latex has a pungent smell, which does not meet environmental protection requirements

Abstract

The invention discloses a polyurethane adhesive composition used for application of gum in artificial grass, and the withdrawal force showed by bottom back of the artificial grass using the polyurethane adhesive, and the cost is lower. The polyurethane adhesive composition used for the application of gum in the artificial grass comprises the components based on the parts by weight: 100 parts of polylol, 10-30 parts of chain extendor, 0.1-5 parts of catalyst, 0.1-5 parts of surface active agent, 0.1-3 parts of pigment, 0.1-3 parts of thixotropic agent, 100-300 parts of filler and 10-100 parts of organic polyisocyanates.

Description

technical field [0001] The invention relates to an adhesive composition, in particular to a polyurethane adhesive composition for artificial turf 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...
