Problems solved by technology

[0005] With the continuous improvement of people's living standards, the demand for artificial turf is also increasing; at present, because the back glue used in artificial turf contains more calcium powder, styrene-butadiene rubber and other materials, the artificial turf is only discarded after being discarded. It can be thrown away as garbage and cannot be recycled again; most of the adhesives currently used are carboxylated styrene-butadiene latex, but it has a strong smell and is not environmentally friendly. Therefore, the use of carboxylated styrene-butadiene latex for the reinforcement of artificial turf is also a helpless move, and technological innovation is imperative

Abstract

The invention discloses recyclable artificial turf. An adhesive comprises, in parts by mass, 30-40 parts of a styrene-acrylic emulsion, 5-10 parts of filler, 0.5-0.8 parts of an antifoaming agent, 0.5-1 part of a thickening agent, 0.3-0.6 parts of a dispersing agent, 15-50 parts of an ethylene-vinyl acetate copolymer, 20-80 parts of a propene-ethylene copolymer, 20-80 parts of a polyolefin plastomer and 5-30 parts of an amorphous alpha-olefin copolymer. The non-woven fabric adhesive for the recyclable artificial turf and a preparation method of the adhesive are designed, the recyclable artificial turf is acid-resistant, base-resistant and corrosion-resistant, the aging-resistant life is longer than 8 years, the withdrawal force is larger than 40 N, and the artificial turf can be completely recycled through cleaning, crushing and extrusion granulation after being used for 8-10 years.

Description

technical field [0001] The invention relates to the technical field of production and processing of artificial turf, in particular to a recyclable artificial turf and a preparation method thereof. Background technique [0002] Artificial turf originated in the United States in the 1960s. It can meet the needs of all-weather high-intensity sports, and has the advantages of simple maintenance, rapid drainage, durability, and low water consumption. It is widely used in hockey, baseball, rugby and other special venues. and recreational and environmental landscape venues. [0003] Artificial turf is composed of three layers of materials. The base layer is composed of tamped coating, gravel layer and asphalt or concrete layer. The base layer requires solid, non-deformable, smooth surface and impervious; Composed of rubber or foam plastic, the rubber has moderate elasticity, and the cost of plastic foam is low, but the elasticity is poor. The lawn that is too thick is too soft and...
