Artificial turf as well as gum application process and production device thereof

Abstract

The invention relates to an artificial turf as well as a gum application process and a production device thereof. The gum application process comprises the following steps of: (1) winding the artificial turf and a base fabric on a drying barrel, transmission rollers and a cooling barrel; (2) spraying gum to the back of the artificial turf; (3) flattening and fixing root parts of grass filaments after heating the drying barrel; and (4) cooling the composited artificial turf through the cooling barrel. The gum application production device comprises a spraying device, a driving device, a control device, a transmission device, the drying barrel and the cooling barrel, wherein the drying barrel is arranged between a composite transmission roller and a first transmission roller, the cooling barrel is arranged between a second transmission roller and a third transmission roller, and a glue spraying device is arranged in front of the drying barrel. The artificial turf comprises a base layer and the grass filaments, wherein the root parts of the grass filaments are fixedly connected with the base layer and the base fabric by using the gum, and the root parts of the grass filaments are of a flat structure. According to the invention, gum consumption is reduced, pullout strength of the grass filaments is increased, drying time is short, production field is reduced, and raw materials and energy sources are saved. The artificial turf provided by the invention has the advantages of high strength, thick gum layer, light weight, low cost, convenience for paving and long service life.

Description

technical field [0001] The invention relates to artificial turf, in particular to an artificial turf adhesive process and a production device used in the process. Background technique [0002] At present, the back glue technology and process in the production of artificial turf is to transport carboxylated styrene-butadiene latex or polyurethane glue to the back of the artificial turf to be back glued through the feeding pump and pipeline, and then scrape the glue on the base cloth with a scraper After reaching a certain thickness evenly, send the artificial turf after adhesive backing to the oven for drying. Using this production process and machinery has the following disadvantages: 1. The amount of glue applied is large; The bottom surface protrudes outward in a circular arc shape, and the distance of the protrusion is relatively large. After scraping the glue with a scraper, the glue at the root of the artificial grass is easily scraped away, so that there is no glue at ...

Problems solved by technology

[0002] At present, the back glue technology and process in the production of artificial turf is to transport carboxylated styrene-butadiene latex or polyurethane glue to the back of the artificial turf to be back glued through the feeding pump and pipeline, and then scrape the glue on the base cloth with a scraper After reaching a certain thickness evenly, send the artificial turf after adhesive backing to the oven for drying. Using this production process and machinery has the following disadvantages: 1. The amount of glue applied is large; The bottom surface protrudes outward in a circular arc shape, and the distance of the protrusion is relatively large. After scraping the glue with a scraper, the glue at the root of the artificial grass is easily scraped away, so that there is no glue at the root of the grass, thereby reducing the artificial grass. Grass pull-out strength; 3. In order to enhance the pull-out strength of artificial turf, continue to increase the amount of glue, so that the thickness of the glue layer of artificial turf is larger, and the amount of glue is further increased; 4. Due to the large amount of glue, The cost rises, the curing time of the glue is prolonged, and the energy consumption of the oven is more; 5. Due to the increase in the amount of glue used, the unit weight of the artificial turf increases, and the transportation cost increases; 6. Due to the thick glue layer, after the ambient temperature decreases, The base cloth with adhesive backing is easy to be brittle and peeled off; 7. The production equipment is large in size, occupies a large area, and the equipment cost is high
