Viscose, high-performance artificial turf and preparation method thereof

Abstract

The invention discloses polyurethane viscose for preparing a high-performance artificial turf and a preparation method thereof, a method for preparing the artificial turf by using the viscose and the artificial turf obtained by the method. The polyurethane viscose is prepared from the following raw materials in part by mass: 100 parts of polyalcohol, 5 to 15 parts of chain extender, 0 to 5 parts of color paste, 100 to 200 parts of inorganic filler, 0.5 to 1.5 parts of catalyst, 30 to 100 parts of water inhibitor and 30 to 100 parts of isocyanate. The method for preparing the artificial turf by using the viscose comprises the following steps of: uniformly spraying the raw materials onto a main bottom lining of the artificial turf through a mechanical pump, scraping the materials through a scraper, pre-heating the materials by infrared, heating the materials in a drying channel, and finally curing, perforating and packing the materials. 600 to 1,000 grams of viscose is applied to each square meter of artificial turf, the tested pullout force of the grass can be more than 80N after the artificial turf is placed for 24 hours at the room temperature, and the main bottom lining is soft and has good toughness.

Description

technical field [0001] The invention relates to a polyurethane adhesive for preparing high-performance artificial turf and a preparation method thereof, a method for preparing artificial turf by using the adhesive, and an artificial turf obtained by the method. Background technique [0002] In the 1960s, a military project in the United States invented artificial turf technology. Because only a small amount of maintenance costs are required, artificial turf quickly gained the favor of site users. In the past 50 years of continuous research and development, artificial turf has been improved in many aspects such as manufacturing materials, weaving technology, and filling materials. Today's artificial turf has been widely used in football, basketball, tennis, hockey, rugby, and golf. and leisure places. In recent years, the difference between it and natural turf has been shrinking. After entering the 21st century, the use of artificial turf has become more rational, and its ...

Problems solved by technology

[0003] In the process of use, people also found that artificial turf has brought negative problems: on the one hand, the traditional adhesive (styrene-butadiene latex) has limited cohesiveness. The main underlayment falls off, which greatly reduces the service life of the artificial turf and requires a lot of maintenance costs, which is why the artificial turf attaches great importance to the index of grass silk pull-out force; on the other hand, the main The backing is harder than the natural turf, and the cushioning force is reduced, leading to an increase in the number of injured athletes. Long-term use of artificial turf even leads to a special disease - Astro's toe disease. The hardness of the artificial turf makes athletes feel uncomfortable. Safety

Therefore, the adhesive polymerized by polyether polyol has a lower glass transition temperature, and has better weather resistance, hydrolysis stability and mold resistance, but poor mechanical properties.
