AI Technical Summary

Technical Problem

Existing artificial turf adhesives are difficult to effectively fix the grass fibers in extreme environments, especially under high temperature and humidity conditions, leading to the problem of grass fibers falling off.

Method used

An adhesive composition is formed by combining an ethylene-vinyl acetate copolymer emulsion and a functional resin emulsion, along with appropriate amounts of surfactants and inorganic fillers. This aqueous system enhances the permeability and bonding strength of grass fibers during the backing adhesive production process.

Benefits of technology

In high temperature and high humidity environments, the adhesive composition can effectively improve the single-strand pull-out strength of grass fibers, ensuring that the grass fibers do not fall off during long-term use. Moreover, the production process has low environmental requirements and is suitable for industrial continuous production.

Abstract

The present application belongs to the technical field of artificial turf. Disclosed are an adhesive composition for artificial turf, artificial turf and preparation methods therefor. The adhesive composition for artificial turf comprises the following components by mass percentages: 10-50% of an ethylene-vinyl acetate copolymer emulsion in which the average particle size of latex particles is less than 3 μm; 5-40% of a functional resin emulsion in which the average particle size of latex particles is less than 3 μm; 0.1-10% of a surfactant; and 0-80% of an inorganic filler. The composition is an aqueous system, the requirement for the environment is low during a gum production process, a gum-coated turf bottom side has a good bonding strength, and the bonding strength of an inner single grass yarn, which is the most difficult to permeate, of the artificial turf is still kept well in a high-temperature and high-humidity environment after hot water aging.
