[0035] Example 1

[0036] Preparation of the polyurethane adhesive composition for the bottom and back of artificial turf: at room temperature, 100g of modified nano-inorganic fillers were dispersed in 90g of castor oil by means of superoscillation and mechanical stirring to obtain their mixed solution, and 10g of them were quickly reduced to two Ethylene glycol, 2g of nickel diacetylacetonate, 1g of fumed silica, 1g of anionic surfactant and 1g of pigment are put into a stirring tank, and stirred rapidly with a high-speed disperser for 3 minutes at a speed of 500 rpm ; Then add 64.3g of diphenylmethane diisocyanate, stir rapidly for 1 minute to make it evenly mixed, and the viscosity is 5000mPa·s. Use the polyurethane adhesive of the present invention to coat the bottom back of artificial turf, so that its glue amount is 800g / m 2 , then heat-cured at 100°C for 3 minutes, and then left to stand at room temperature for 24 hours. According to the ISO4919 standard, use the univ...

Abstract

The invention discloses a castor oil modified polyurethane adhesive combination for an artificial turf gum. The adhesive combination wholly or partially substitutes petro-derived polyalcohol polyurethane adhesive by using renewable material-derived castor oil as polyalcohol to reduce cost, improve processability and ensure environmental friendliness, and simultaneously based on the synergetic effects of modified nano inorganic fillers and the castor oil, maintains the required important performance of the artificial turf, such as withdrawal force, processability, viscosity and curing rate. The polyurethane adhesive combination for the artificial turf gum comprises the following components in portions by weight: 50-98 portions of castor oil, 0-50 portions of polyalcohol, 2-30 portions of chain extender, 0.1-3 portions of catalyst, 0.1-3 portions of surfactant, 0.1-3 portions of pigment, 0.1-3 portions of thixotropic agent, 100-300 portions of modified nano inorganic filler and 10-100 portions of organic polyisocyanate.

Description

technical field [0001] The invention relates to an adhesive composition, in particular to a castor oil modified 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 o...
