Description

Technical Field

[0001] The utility model belongs to the technical field of artificial turf, and more specifically relates to a bottom-reinforced artificial turf. Background Art

[0002] After nearly 60 years of development, artificial turf has become increasingly similar to natural turf in appearance and feel. Moreover, due to its advantages in installation and maintenance, it has been increasingly accepted by people, and its application scenarios are constantly expanding.

[0003] While artificial turf products provide comfort and convenience for users, they also have many problems, including color difference of the grass surface, grass shedding, etc. In recent years, more and more artificial turf venues, especially sports venues, have experienced a series of serious problems such as degumming at the turf joints, deformation of the turf, and bulging of the turf, which have affected the normal use of the venues. The main reason is that the base fabric used in the production process of artificial turf is an organic polymer material. During the process of back gluing in the production of artificial turf, this material will be stretched to a certain extent due to the heating of the oven and the tension of the traction roller, resulting in a certain degree of deformation. Later, after paving and use, due to this deformation and the deformation of the material itself due to thermal expansion and contraction, the venue is prone to problems such as degumming at the joints, deformation and bulging.

[0004] Therefore, it is urgent to develop an artificial turf with high bottom strength and strong deformation resistance to solve the increasingly serious problems of shrinkage and bulging of artificial turf products and meet market demand. Utility Model Content

[0005] In view of this, the utility model provides a bottom-reinforced artificial turf.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A back-reinforced artificial turf comprises, from top to bottom, a grass fiber layer, a base fabric layer and an adhesive layer, wherein the grass fiber layer is tufted on the base fabric layer, and the grass fibers penetrate the base fabric layer;

[0011] Beneficial effects of the utility model: Compared with the prior art, the back-reinforced artificial turf designed by the utility model has the following advantages: first, the utility model selects a heavy-weight glass fiber mesh as the core layer of the entire backing layer, and after combining with the adhesive, it enhances the turf's ability to resist deformation in harsh environments, especially in high and low temperature environments, and can resist a series of problems such as turf deformation and bulging caused by thermal expansion and contraction; secondly, a coating layer designed in the utility model allows the adhesive to penetrate into the interlayer to a certain extent during the coating process and form a layer with the glass fiber mesh cloth. A certain degree of combination is achieved, thereby promoting the improvement of the deformation resistance of the entire backing. At the same time, this coating layer has a certain degree of barrier effect on the adhesive, which will not make the bond between the adhesive and the glass fiber mesh cloth too strong, avoiding excessive glue penetration that causes the entire backing layer to be too hard and affects the subsequent punching and rolling processes; finally, the backing-enhanced artificial turf designed by the utility model has a simple structure and is suitable for mass production. Existing production equipment can be used without modification, saving costs. The backing-enhanced artificial turf designed by the utility model can save manpower, save costs, and is conducive to industrial production and market promotion.

[0172] In order to characterize the deformation resistance of the lawn, we measured the dimensional stability of the lawn according to the method in EN 13746:2004. The test results are shown in Tables 1 to 5.

[0173] Test sample preparation:

[0174] Examples 1-22 are examples of artificial turf samples with enhanced bottom backing, and Comparative Examples 1-5 are examples of ordinary artificial turf samples.

[0175] Dimensional stability test process:

[0176] Step 1:

[0177] Randomly select three test samples from the prepared test samples, each with a length and width of (400±10) mm. Make three marks on the four edges of each sample, two of which are 50 mm away from the right angle, and the other is in the middle of the edge line;

[0178] Step 2:

[0179] Place the marked samples in an environment with a relative humidity of (50±5)% and a temperature of (23±2)°C for at least 48 hours, and measure the length and width of the samples respectively;

[0180] Step 3 (immersion environment):

[0181] Immerse the sample in step 2 in an aqueous solution containing 0.1% sodium dodecyl sulfate at a temperature of (23±2)°C, take it out after soaking for (24±1) hours, and measure the length and width of the sample within 5 minutes;

[0182] Step 4 (freezing environment):

[0183] After completing step 3, immediately place the sample at a temperature of (-18±2)°C, and take it out after (24±1) hours to measure the length and width within 5 minutes;

[0184] Step 5 (heating environment):

[0185] After completing step 4, immediately place the sample at a temperature of (70±2)°C, and take it out after (72±1) hours to measure the length and width within 5 minutes;

[0186] Step 6 (room temperature):

[0187] After completing step 5, immediately place the sample in an environment with a relative humidity of (50±5)% and a temperature of (23±2)°C for (48±1) hours, and measure the length and width.

[0188] The dimensional change at each stage is calculated according to the following formula:

[0189] △L=(L m -L 0 ) / L 0 ×100

[0190] Where L 0 is the initial length of the sample, Lm is the length of each stage, with a minus sign indicating a decrease in size and a plus sign indicating an increase in size.

[0191] Table 1

[0192]

[0193]

[0194] From the data comparison in Table 1, it can be seen that the bottom-reinforced artificial turf of the utility model has greatly improved dimensional stability in both the length direction and the width direction compared with the current ordinary artificial turf.

[0195] Table 2

[0196]

[0197] From the comparative data in Table 2, it can be seen that when the thickness of the high-permeability woven fabric weft yarn changes from thick to thin, the dimensional stability of the lawn generally shows a trend of changing from good to bad. The reason is that as the thickness becomes thinner, the permeability of the woven fabric becomes worse, which makes the bonding between the adhesive layer and the glass fiber mesh cloth worse, thereby affecting the deformation resistance of the backing. In particular, when the thickness of the weft yarn deviates from the preferred range of 0.08-0.5mm of the utility model, the dimensional stability of the artificial turf prepared therefrom is close to that of ordinary artificial turf and cannot meet the use requirements.

[0198] Table 3

[0199]

[0200] From the comparative data in Table 3, it can be seen that when the gram weight of the glass fiber mesh cloth changes from large to small, the dimensional stability of the lawn generally shows a trend of changing from good to bad. The reason is that the glass fiber mesh cloth plays a reinforcing role in the base fabric layer of the utility model. As the gram weight decreases, its reinforcing effect weakens, especially when the gram weight is reduced to a value out of the preferred range of 8 to 200 g / m 2 When the dimensional stability of the artificial turf is close to that of ordinary artificial turf, it cannot meet the use requirements. In addition, when the gram weight of the glass fiber mesh reaches 200g / m 2 Problems such as tufting and punching difficulties have already appeared. When the weight increases further, the subsequent problem of inability to carry out continuous production will be faced.

[0201] Table 4

[0202]

[0203]

[0204] It can be seen from the data in Table 4 that the back-reinforced artificial turf of the utility model has excellent dimensional stability. When the gram weight of the ordinary woven fabric is less than 80g / m 2 When the weight is greater than 200g / m, the dimensional stability of the base fabric itself is problematic and it is no longer possible to weave a base fabric that can be used normally. 2 There are problems in the tufting process during normal production because the base fabric weight is too large and tufting cannot be produced continuously.

[0206]

[0207] It can be seen from the data in Table 5 that the back-reinforced artificial turf of the present invention has excellent dimensional stability.
