Problems solved by technology

The incomplete polyolefin and incomplete ethylene polymer material containing EVA used in this patent can be used as the adhesive layer of artificial turf. Although it can be recycled to a certain extent, there are also several problems. First, EVA contains vinyl acetate. , the elasticity and strength retention rate after recycling will be severely reduced, and what is more fatal is the incompatibility of components. After recycling and granulation, the physical properties are severely reduced and there is almost no use value.
Second, there must be additional equipment, which is to install a T-shaped film head on the extruder. This is non-standard equipment, and it is difficult to balance investment and return.
Third, it is difficult to industrialize how to smoothly extrude the 4-meter-wide T-shaped polyolefin film layer and cooperate with the lawn to fuse and coagulate into rolls

Abstract

The invention relates to a recyclable artificial turf. The recyclable artificial turf comprises grass fibers, bottom cloth and an adhesive layer; the bottom cloth is arranged under the grass fibers; the adhesive layer is arranged under the bottom cloth; during preparation, firstly, components of glue water in weight parts are 95-100 parts of aqueous polyolefin dispersion, 0.5-1 parts of thickeningagents, 1-5 parts of deionized water and 2-3 parts of pigment fillers; secondly, the turf is correspondingly coated for two times, coated and dried; and thirdly, the turf is perforated and cut to obtain the recyclable artificial turf. According to the recyclable artificial turf, the preparation method is simple, the steps are easy to operate, the wire drawing performances, such as breaking strength, elongation, wire drawing section and appearance, of the prepared recyclable artificial turf satisfy requirements of manufacturing the artificial turf through wire redrawing, and better water resistance is realized.

Description

technical field [0001] The invention relates to a recyclable artificial turf, which belongs to the technical field of artificial turf preparation. Background technique [0002] After the existing traditional artificial turf tufting is manufactured, the last back coating process is carried out, usually using styrene-butadiene latex or polyurethane emulsion to coat and bake, so that the grass fibers are more firmly embedded in the base fabric and the pulling out of the grass fibers is increased. force. Grass silk is generally made of polyethylene PE or polypropylene PP plastic wire drawing, and the base fabric is woven from polypropylene PP plastic. When artificial turf needs to be recycled after several years of use, people will encounter great challenges and difficulties. First, polyethylene PE or polypropylene PP plastics and styrene-butadiene latex or polyurethane emulsion are two completely different chemical substances, and their structures and properties are quite dif...
