Description

A kind of high-permeability water bottom cloth, artificial turf containing it and preparation method

technical field

The invention relates to the technical field of artificial turf, in particular to a high-permeability water base fabric, a preparation method of the high-permeability water base fabric, an artificial turf containing the same and a preparation method.

Background technique

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. With the continuous development of artificial turf manufacturing technology, its appearance and feel are getting closer to natural turf, but it is simpler than natural turf in terms of paving and maintenance, and its maintenance cost is low, and it is less affected by the environment, weather and region. With the continuous expansion of artificial turf application scenarios, more and more people accept it and pave it in football fields, courtyards, roofs and office buildings. Artificial turf is mainly composed of three parts, namely synthetic grass fibers imitating grass blades, a base cloth for implanting synthetic fibers, and a back glue layer for fixing. In the process of use, artificial turf not only pays attention to the appearance and the mechanical properties of the back, but also pays attention to its water permeability.

In order to solve the problem of water seepage, the current artificial turf products use electric iron to punch holes after the adhesive process to ensure the water seepage rate of the product, but the holes punched by electric iron will cause natural weeds to grow out during the long-term use of the artificial turf , causing trouble for subsequent maintenance. Furthermore, some artificial turf will have a sand filling process when paving the site, and the quartz sand will seep through the holes to the bottom of the lawn and contact the adhesive layer. Wear and tear, if things go on like this, it is easy to cause the adhesive layer to fall off, and the coverage is not good, which eventually leads to the fall of the grass silk.

Therefore, it is necessary to develop an artificial turf that does not punch holes and has excellent water seepage performance, so as to improve the durability of the bottom back to meet the market demand.

4) The prepared artificial turf is punched according to the size of 10cm×10cm.

Water permeability test:

The water permeability of all samples was tested according to the method in FIFA Quality Program for Football Turf-2015.

Place the sample to be tested at 23±2°C for at least 4 hours before testing.

Clamp the sample to be tested with two metal or plastic rings with an inner diameter of 300mm±2mm, and place a support grid under the clamped sample to prevent the sample from being compressed and deformed by a large amount of water injection during the water penetration test. The grid must ensure that the maximum deformation from the outside of the ring to the center does not exceed 5mm. After clamping, use a sealant to seal the cracks to prevent water leakage. After the test device is completed, inject 5L of water into the ring to wet the sample to be tested, and at the same time check whether the test device leaks. If there is, the device needs to be resealed. This leak detection process needs to be carried out for at least 30 minutes.

After the preparations are done, make sure that the test device is in a horizontal state before the test starts, and then inject a large amount of water into the device to ensure that the water surface exceeds the height of the back of the sample to be tested by 70-90mm, and start timing when the water level drops to 30mm from the back of the bottom , record the time taken to drop from 30mm to 10mm, accurate to 0.1 second, if the penetration speed is slow, the test should be stopped at 30min.

Repeat the test twice according to the above method, and take the average of the last two results.

The water seepage rate (I _c ) is calculated according to the following formula:

I _c =F _wc /t _c

in:

F _wc is the height of water level drop (mm), usually 20mm;

t _c is the time taken for the water level to drop to a certain height (h);

Judgment method of water seepage performance:

At present, in order to solve the problem of water seepage, conventionally produced lawns in the industry need to be drilled with electric soldering iron after the adhesive process. The water seepage performance of this kind of lawn is tested according to the FIFA test method. The water seepage rate is within 8000-12000mm/h, which is basically OK. It meets the demand, but in order to avoid a large amount of water accumulation in heavy rain and other scenes, the water seepage rate needs to reach more than 15000mm/h. Therefore, it is considered that the lawn with a water seepage rate above 15000mm/h is a lawn with high water seepage.

Durability performance test:

Initial pull-out force:

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, place the sample block to be tested on the electronic universal testing machine to clamp half a tuft of grass silk with clamps perpendicular to the direction of the sample block, turn on the machine, and record the maximum force value after the grass silk is completely pulled out is the pull-out force value of grass silk, and the pull-out force value for each sample block is based on the average value of 10 sample data.

Pull-off force after long-term use:

To simulate the actual use of the lawn, the newly prepared 40cm*80cm sample to be tested is subjected to a rolling wear resistance test using a Lisport wear tester. Pour 100kg of water on the sample to be tested, let it permeate naturally for 1 minute, and then continue to use the Lisport wear tester to roll the test for 30,000 revolutions. Methods Carry out water seepage and wear resistance tests in sequence until the accumulated wear resistance test reaches 300,000 revolutions. After the simulation experiment, the pull-out force test was carried out according to the method in ISO4919.

Coverage of the back after long-term use:

After simulating the long-term use of the sample, observe the rubber layer coverage of the bottom and back, and judge that the bottom and back are well covered and no glue layer falls off as ☆☆☆, and the bottom and back cover is average, and some glue layers fall off as ☆☆, The bottom and back cover are not good, and most of the glue layer is peeled off. It is judged as ☆.

Examples 1-6 and Comparative Examples 1, 2, and 4 were tested according to the above water permeability test and durability test methods, and the results are shown in Table 1.

Table 1

From Example 1 to Example 6 in Table 1, it can be seen that when the thickness of the selected weft yarn is 0.08-0.5mm, the prepared artificial turf has a good water seepage effect. When it is simulated for the actual use of artificial turf , because it does not punch holes and has good water permeability, its back coverage and mechanical properties after the simulation test are good, especially when the thickness of the weft yarn is between 0.1 and 0.3mm, the mechanical properties after the simulation test are excellent. Compared with other examples, Example 5 and Example 6 have lower coverage and mechanical properties after long-term use, mainly because the weft yarn is too thick, resulting in too large pores in the base fabric and a small amount of quartz sand leakage.

From the situation of comparative example 1 and comparative example 2, because the thickness of the weft yarn is less than 0.08mm, no effective hole is formed at the intersection of warp and weft yarns, resulting in poor water seepage performance. The stagnant water state aggravates the aging of the adhesive layer, making the bottom and back coverage and mechanical properties unsatisfactory after long-term use. From the situation of Comparative Example 4, even though the lawn has a certain degree of water permeability, a large amount of quartz sand leaks to the back of the bottom due to the existence of the holes punched by the electric iron, and the back of the bottom is severely worn during use. The mechanical properties are poor.

From Comparative Example 6, it can be seen that when the ratio of the original glue to the filler is less than 2:8, too much filler will affect the mechanical properties of the glue layer, resulting in poor pull-off force of the lawn before and after the simulation, and the simulated The coverage on the back of the test was also less than ideal.

Excellent performance.
