[0019] Figure 2 The schematic view of the utility model provided with the mesh cloth is shown in the figure.
[0020] Mark: 1-grass layer, 2-woven cloth, 3-mesh cloth, 4-foamed adhesive layer. DETAILED DESCRIPTION
[0021] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the specific implementation manner of the utility model will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creative labor, and other embodiments can be obtained.
[0022] The technical scheme of the utility model will be described in detail below with specific embodiments.
[0023] For example, Figure 1The utility model provides a kind of lawn with bottom can be recycled, due to weaving cloth 2 and back adhesive layer are bonded fixed, the recycling of lawn is at least simultaneously recycling weaving cloth 2 and back adhesive layer, specifically, lawn includes grass silk layer 1, weaving cloth 2 and foamed back adhesive layer 4, grass silk layer 1 is set on weaving cloth 2, foamed back adhesive layer 4 is set on the bottom surface of weaving cloth 2, and grass silk layer 1 is fixed with weaving cloth 2, wherein, weaving cloth 2 is PP plain weave cloth, and the weight is 90~150g / m 2 , preferably, the weight is 120g / m 2 .
[0024] PP is polypropylene, which is a thermoplastic synthetic resin. In the lawn, the grass silk and the weaving cloth 2 account for the vast majority of the total mass, the utility model adopts the foamed back adhesive layer 4, realizes the light and thin of the lawn, more importantly, the use of the foamed back adhesive layer 4 can reduce the amount of glue, thereby reducing the proportion of the foamed back adhesive layer 4 in the total mass of the lawn. When recycling the lawn, the grass silk layer 1 can be pulled out of the weaving cloth 2, and the weaving cloth 2 and the foamed back adhesive layer 4 can be directly recycled.
[0025] Preferably, the grass silk layer 1 is composed of grass silk made of PP material. The grass silk layer 1 and the weaving cloth 2 layer of the utility model are made of the same material, which can be directly melted and reused when recycling. The PP material obtained after melting can be used to make new weaving cloth 2 or grass silk.
[0026] Further, the weaving cloth 2 is formed by black and white colored warp and weft, white and white colored warp and weft, or white and gray colored warp and weft. The warp and weft refer to the warp and weft that form the weaving cloth 2. The black and white colored warp and weft means that one of the warp and weft is white and the other is black. Similarly, the white and white colored warp and weft means that both the warp and weft are white. The white and gray colored warp and weft means that one of the warp and weft is white and the other is gray.
[0027] In this application, the color of the weaving cloth 2 is mainly white, with black, white or gray. As can be easily understood, artificial grass silk is generally green. When recycling and melting, the white part of the weaving cloth 2 will not significantly change the color of the molten material. The gray part and the green grass silk are mixed and melted to produce a green color similar to an ecological natural landscape. The black part will darken the color of the molten material, even turning it black. When the color of the weaving cloth 2 is white + white or white + gray, the molten material can be used as raw material to produce artificial grass silk by adding appropriate colorants. When the color of the weaving cloth 2 is white + black, the molten material can be used as raw material to produce weaving cloth 2 by adding black colorants.
[0028] In the utility model, the number of weaving cloth 2 can be two layers. When the foamed back adhesive layer 4 is set, the glue will penetrate into the two layers of weaving cloth 2 to bond and fix the two layers of weaving cloth 2.
[0029] Further, the lawn further comprises a white mesh cloth 3, as shown in the figure. Figure 2 The mesh cloth 3 is between the foamed back adhesive layer 4 and the woven cloth 2, and the foamed back adhesive layer 4 bonds and fixes the mesh cloth 3 and the woven cloth 2. The mesh cloth 3 avoids the stitches of the grass filaments on the woven cloth 2 from being obviously protruding, and also enhances the overall strength of the lawn. The mesh cloth 3 is white, facilitating recycling, and when the white woven cloth 2 is mixed with other colored materials, the other colors are diluted, without changing the color system of the molten material. By adding appropriate colorants, the molten material can be directly used to produce the grass filaments or the woven cloth 2. Preferably, the mesh cloth 3 comprises warp threads of PP material and weft threads of PTE material. PTE is polyester resin, and the mixing of PTE and PP can improve the performance of the material.
[0030] In the utility model, the mesh size of the mesh cloth 3 is 5*5mm 2 ~ 10*10mm 2 .
[0031] It is easy to understand that when the lawn is provided with the woven cloth 2 and the mesh cloth 3 at the same time, since the white part of the material accounts for most of the woven cloth 2 and the mesh cloth 3, colorants can be added according to the needs of recycling and producing the grass filaments or the woven cloth 2, for example, the woven cloth 2 with white and white color matching or white and gray color matching is mixed with the white mesh cloth 3 and the green grass filaments, and after being fused, the molten material is light green in color, and the molten material can be used to produce the grass filaments again by adding green colorants to deepen the green color. The woven cloth 2 with black and white color matching is mixed with the white mesh cloth 3 and the green grass filaments, and after being fused, since there is more white material, the molten material is dark green in color, and the molten material can be used to produce dark green grass filaments, or black colorants are continuously added to change the molten material into black, and the molten material is used to produce black warp threads or weft threads of the woven cloth 2.
[0032] Further, the weight of the mesh cloth 3 is less than the weight of the woven cloth 2, facilitating subsequent recycling.
[0033] Further, the thickness of the foamed back adhesive layer 4 is 3-10mm. Preferably, under the premise of arranging the mesh cloth 3, the thickness of the foamed back adhesive layer 4 is 3-5mm. The foamed back adhesive layer 4 covers the stitches of the grass filaments, and also bonds the woven cloth 2 and the mesh cloth 3. Since the mesh cloth 3 exists, the stitches of the grass filaments are effectively protected, so the amount of the foamed back adhesive layer 4 can be reduced, thereby reducing the content in the molten material.
[0034] The above has carried out the detailed elaboration to the embodiment provided by the utility model. The principle and implementation mode of the utility model have been described by applying specific examples in this paper, and the above embodiment description is only for helping understanding the core idea of the utility model. It should be pointed out that, for ordinary skilled person in the art, without departing from the principle of the utility model, the utility model can be improved and modified, and these improvements and modifications also fall within the protection scope of the utility model claim.
