Problems solved by technology

Aiming at the problem of the bonding strength of the current water-based adhesives, some manufacturers have also tried to use some methods to improve them, but they have failed to achieve satisfactory results.
Patent No. CN201610414276 discloses an artificial turf adhesive composition with excellent performance. This composition can improve the bonding strength of the backing to a certain extent, but the improvement is limited.
[0004] The water-based adhesive composition in the prior art has a certain bonding strength, but there are problems such as degumming after long-term use and a significant decrease in bonding strength, which is far from being achieved when it is applied to sports venues with higher performance requirements. It can meet the requirements of long-term use, so it is necessary to develop a high-performance water-based adhesive composition for artificial turf to solve the problems in the prior art, so as to meet the growing needs of the market

[0026] Preparation method of test sample:

[0027] (1) Tuft the twisted artificial turf on the base fabric with a specified line spacing and needle spacing with a tufting machine to form a semi-finished artificial turf;

[0028] (2) The water-based adhesive composition prepared by the embodiment and the comparative example according to 1.2kg / m 2 The amount is painted on the bottom and back of the semi-finished lawn, and the test sample is obtained by curing in an oven.

[0029] Sample performance test method:

[0030] Initial pull-out force:

[0031] Use an electronic universal material testing machine to test according to the method in the standard ISO4919, specifically to intercept a newly prepared sample block of 20cm*20cm, and place it at a relative humidity of (65±4)% and a temperature of (20± 2) Under the environment of ℃ for 24 hours, put the sample block to be tested on the electronic universal material testing machine and clamp half a tuft of grass silk with clamps...

Abstract

The invention discloses a high-performance water-based adhesive composition for an artificial turf. The composition makes the bottom back have an excellent bonding strength, so the bonding strength ofthe back adhesive layer is still good after the artificial turf are used for a long term. A filler is modified with a dibasic organic acid to introduce carboxylic acid groups, a carboxylic acid typeionomer emulsion is introduced for rubber latex and the carboxylic acid groups in the modified filler, metal ions in the ionomer emulsion and carboxyl groups form ionic bonds and coordinate bonds in order to construct a crosslinked network structure between the rubber latex and the modified filler, and the melting of the carboxylic acid type ionomer emulsion during heating curing is used to enhance the bonding force between the adhesive layer and grass silks, so the adhesive composition prepared by the method keeps a very high bonding strength and has no degumming or grass falling phenomenon regardless in the initial stage or after long-term use after being applied to the artificial turf for sports.

Description

technical field [0001] The invention relates to a water-based adhesive composition and a preparation method thereof, in particular to a high-performance water-based adhesive composition for artificial turf and a preparation method thereof, belonging to the field of adhesive preparation. Background technique [0002] In April 1966, the world's first artificial turf was born at the Space Dome Stadium in Houston, USA. Since then, artificial turf has officially entered the world stage. Artificial turf is mainly composed of three parts, namely synthetic grass fibers imitating grass blades, a base cloth for implanting synthetic fibers, and an adhesive layer for fixing. After half a century of development, grass silk has changed from the nylon used at the beginning, to the polypropylene used later, and then to the polyethylene used now. The softness, appearance and sports performance of the grass have become closer and closer to natural grass. widely accepted by users. When the a...
