Abstract

The invention discloses a preparation method for high-strength artificial turf polyurethane gum. The preparation method comprises the steps that a hydroxyl-terminated polyurethane pre-polymer obtained through a synthetic reaction of difunctional polyether, trifunctional polyether, methylene diphenyl diisocyanate and a little amount of high-boiling-point solvent under a certain condition is utilized to be composited with polyether of different functions, a micromolecular chain extender, an inorganic filler, a wetting dispersant, an organic silicon coupling agent, color paste, a catalyst and the like to serve as a first component of the adhesive; polyisocyanate serves as a second component of the adhesive, and the two components are compounded in proportion to obtain the high-strength artificial turf polyurethane gum. The prepared high-strength artificial turf polyurethane gum has the advantages of being lower in viscosity, long in normal temperature potlife, high in heating and curing speed, good in bonding effect and the like and especially has the very high mechanical strength, the turf drawing force reaches 70 N or above, and the requirements of a high-end artificial turf, especially a sports turf, for the high-strength gum are completely met.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a method for preparing a high-strength polyurethane artificial turf adhesive which is suitable for coating on the back of artificial turf to anchor grass filaments. Background technique [0002] Polyurethane artificial turf adhesive is mainly used at the bottom of artificial turf to anchor the grass filaments. [0003] Artificial turf was born in the United States in the 1960s. It is a artificial lawn made of non-living plastic chemical fiber products as raw materials. Unlike natural turf, it does not need to consume resources such as fertilizers and water necessary for growth. It can meet the needs of high-intensity sports 24 hours a day, and has simple maintenance, rapid drainage, and excellent site flatness. At present, artificial turf has been widely used in special venues for hockey, baseball, and rugby, public practice fields for sports such as football, tennis, and golf...
