Description
Technical Field
The invention relates to the technical field of artificial grass, in particular to lignin/polyolefin composite artificial grass filaments and a preparation method thereof.
Background
Artificial grass has been developed for over forty years, has the advantages of ageing resistance, sun protection, water resistance, skid resistance, wear resistance, comfortable foot feeling, bright color, long service life, no need of large investment in maintenance cost, all-weather effect and the like, and is undoubtedly to be more and more commonly adopted. The main material of the artificial grass is high molecular polymer, and the consumption of the high molecular polymer as the main component material of the artificial grass is increased along with the wider application of the artificial grass, which inevitably brings pressure to economy, society and ecology.
In the background of a new era, people pay more attention to energy problems, and with the gradual reduction of the quantity of non-renewable resources, people gradually begin to pay attention to renewable resources. Biomass is a typical renewable resource, and lignin is one representative thereof. Nature stores a large amount of lignin, second only to cellulose. Although the storage of lignin is large and renewable, the industrial utilization rate is not up to 10%. However, no article and patent report for applying lignin as a filler to the field of artificial turf have been found so far.
Disclosure of Invention
In order to overcome the defects of the prior art, one of the purposes of the invention is to provide the lignin/polyolefin composite artificial grass filaments, aiming at reducing the cost of the raw materials of the artificial lawn, enhancing the mechanical property, endowing new functions, and simultaneously promoting the utilization of renewable resources and the ecological environment protection; the invention also aims to provide a preparation method of the lignin/polyolefin composite artificial grass filaments.
One of the purposes of the invention is realized by adopting the following technical scheme:
a lignin/polyolefin composite artificial grass filament comprises the following raw materials in percentage by weight: 1-60 wt% of lignin, 30-80 wt% of polyolefin thermoplastic resin and 1-5 wt% of additive, wherein the sum of the raw materials is 100 wt%.
Lignin is a ubiquitous class of high polymers in plants and is the main substance supporting plant growth. Lignin is the most abundant organic polymer next to cellulose in the plant kingdom. The lignin is nontoxic, is a renewable resource, and is cheap and easily available. The artificial grass filaments prepared by matching the lignin and the polyolefin have the advantage of good toughness, and the cost of the artificial grass filaments is also reduced.
Furthermore, the raw material of the lignin is one or a composition of more than two of bagasse, wood or papermaking waste liquid, so that the resource utilization rate is improved, and the waste caused by resources is avoided. The purity of the lignin is 30-90%.
Still further, the lignin is one or a combination of more than two of alkali lignin, organic solvent lignin or alkali lignin. Among them, the organic solvent type lignin is preferred, and the organic solvent type lignin is well preserved because the original molecular structure and the reaction groups contained in the organic solvent type lignin are less involved in chemical reactions in the preparation process. Therefore, when used as a raw material for polymer synthesis or modified products, the organic solvent type has many unique advantages over lignosulfonates and alkali lignins, such as a higher proportion of reactive groups, easy separation from the solvent and purification, and no sulfur impurities. Alkaline lignin modification and purification: 1) performing primary purification by hydrochloric acid precipitation and ultrafiltration; 2) dissolving with anhydrous ether, centrifuging, and oven drying to obtain alkaline lignin.
Further, the polyolefin thermoplastic resin is polyethylene and/or polypropylene.
Polyethylene (PE) is classified into high density polyethylene (low pressure polymerization), low density polyethylene (high pressure polymerization), linear low density polyethylene, and ultrahigh molecular weight polyethylene, and has a melting point of about 120-. PE is excellent in corrosion resistance and electrical insulation (particularly high-frequency insulation), and can be enhanced by chlorination, irradiation, and modification with addition of glass fibers or the like. The high-density polyethylene has higher melting point, rigidity, hardness and strength, small water absorption, and good electrical property and radiation resistance; the low density polyethylene has better softness, elongation, impact strength and permeability. Low Density Polyethylene (LDPE) is preferred as the feedstock.
Polypropylene, PP for short, is a colorless, odorless, nontoxic and semitransparent solid substance. Polypropylene is a thermoplastic synthetic resin with excellent performance, and is colorless translucent thermoplastic light general-purpose plastic. Has chemical resistance, heat resistance, electric insulation, high-strength mechanical property and good high-wear-resistance processing property.
Still further, the additive is one or a composition of more than two of a light stabilizer, an ultraviolet absorber, an antioxidant, a matte agent or a slipping agent. Wherein the ultraviolet absorbent is one or a composition of more than two of 2-hydroxy-4-methoxybenzophenone, 2, 4-dihydroxybenzophenone, 2-hydroxy-4-n-octoxybenzophenone or phenyl o-hydroxybenzoate; the antioxidant is one or the combination of more than two of 2, 6-di-tert-butyl-p-cresol, 4' -di-tert-octyldiphenylamine, 4-hydroxydodecanoic acid anilide or dilauryl thiodipropionate; the slipping agent is one or a composition of more than two of n-butyl stearate, polymethylphenylsiloxane, polyvinyl chloride or paraffin.
The second purpose of the invention is realized by adopting the following technical scheme:
the preparation method of the lignin/polyolefin composite artificial grass filaments comprises the following steps:
1) mixing and stirring lignin and polyolefin, adding an additive, and uniformly stirring to obtain a mixture;
2) feeding the mixture obtained in the step 1) into a wire drawing machine, and melting, extruding, drafting and shaping to obtain the lignin/polyolefin composite artificial grass filaments.
Further, in the step 2), the melting temperature is 160-260 ℃.
Compared with the prior art, the invention has the beneficial effects that:
(1) the lignin/polyolefin composite artificial grass filaments adopt lignin with wide sources and low price as one of raw materials, the lignin has excellent mechanical property, creep resistance, thermal stability, bacteriostasis, aging ultraviolet aging resistance, moisture absorption and moisture elimination and other excellent characteristics, and the addition of the lignin can enable the polyolefin to form heterogeneous crystallization and improve the storage modulus of the material, thereby improving the physical properties of the material. The lignin is used as a novel filler to be applied to the artificial lawn industry, plays a very positive role in the aspects of waste resource utilization, ecological environment protection and the like, and has wide market prospect; compared with the common nylon artificial grass, the lignin/polyolefin composite artificial grass filaments have similar mechanical properties, but the cost is greatly reduced;
(2) the preparation method of the lignin/polyolefin composite artificial grass filaments is simple and convenient, and can be used for industrial large-area production of artificial grass filaments.

The preparation method of the lignin/polyolefin composite artificial grass filaments comprises the following steps:
1) mixing and stirring lignin and polyethylene, adding polymethylphenylsiloxane and 4-hydroxydodecanoic acid anilide, and uniformly stirring to obtain a mixture;
2) feeding the mixture obtained in the step 1) into a wire drawing machine, heating to 200 ℃ to a molten state, extruding in a double-screw extruder, and drafting and shaping to obtain the lignin/polyolefin composite artificial turf.
Comparative example 1
The artificial grass filament is manufactured by nylon and polypropylene which are compounded and sold by Nanjing Langmei carpet company.
Comparative example 2
Comparative example 2 differs from example 1 in that: no lignin was added. The remaining components and preparation were the same as in example 1.
Comparative example 3
Comparative example 3 differs from example 1 in that: no polyethylene was added. The remaining components and preparation were the same as in example 1.
Performance testing
The artificial grass filaments of the examples 1 to 3 and the artificial grass filaments of the comparative examples 1 to 3 are subjected to an artificial grass filament mechanical property technical test, according to the standard of GB-T20394-2019, the cost calculation is calculated according to the cost of the used raw materials, and the specific data are shown in Table 1:
TABLE 1 comparison of mechanical Properties and cost of artificial grass filaments from examples 1-3 and commercially available artificial grass filaments
As can be seen from Table 1, the artificial turf yarns of examples 1 to 3 have similar mechanical properties compared with comparative example 1, and all meet the standard of GB-T20394-2019. However, the cost of the artificial grass filaments of the examples 1 to 3 is lower than that of the comparative example 1, and the nylon used in the comparative example 1 can be degraded, but the degradation period is longer and is far longer than that of the lignin of the examples 1 to 3. Therefore, the artificial turf filaments of the embodiments 1 to 3 have the advantage of low cost, and the resource utilization rate is improved by using the renewable material lignin as the raw material.
Compared with the artificial grass filaments of the comparative examples 2 to 3, the artificial grass filaments of the examples 1 to 3 have better mechanical properties, which shows that the lignin and the polyolefin have a synergistic effect, and the combination of the lignin and the polyolefin can improve the toughness and the durability of the artificial grass filaments.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
