Problems solved by technology

Along with the rapid development of plastic runways, adhesives for plastic runways have been widely researched and produced. At present, there are many types of polyurethane materials for plastic runways on the market. However, due to different raw material selections, formula designs and synthesis processes, the differences between these materials There are large differences in performance, and a large part of the use will cause risks to builders and users, causing environmental pollution

Embodiment 1

[0044] Embodiment 1: the preparation of formula I polymer

[0045] Under a nitrogen atmosphere, 15.0 mmol of 2-(N,N-dimethylaminoesteryl)-3,6-difluoro-8-(1'-naphthyl)-naphthalene, 4,4'-dichlorobenzene 8.0mmol of sulfone, 25mmol of 1-(2,5-dihydroxybenzoyl)pyrene, 30mmol of anhydrous potassium carbonate, 60ml of N,N-dimethylacetamide, and 30ml of toluene were mixed in a reaction vessel and heated in an oil bath to 150°C, water was separated for 4 hours, the toluene was distilled off, the temperature was raised to 190°C, and the reaction was carried out overnight. Slowly pour the reaction solution into 500ml of deionized water to obtain a white strip-shaped polymer, change the water, keep the temperature at 80°C, boil in water three times, each time for 6 hours, dry it, and then dry it under vacuum at 100°C for 24 hours to obtain a white fibrous polymer. Formula I polymer, yield 91.8%. where M w is 2.88×10 5 ,M n 0.75×10 5 , the molecular weight distribution index is 3.84. ...

Embodiment 2

[0048] Embodiment 2: the toxicity test of formula I polymer:

[0049] The PPARδ activity of the inventive polymer represented by formula I was confirmed by transfection assay. In addition, selectivity for the PPAR subtypes PPARα and PPARγ was also examined. Cytotoxicity was tested by MTT assay, and in vivo activity was studied by animal experiments.

[0050] CV-1 cells were used in this assay. The cells were inoculated into 96-well plates containing DMEM supplemented with 10% FBS, DBS (non-specific bovine serum, defatted) and 1% penicillin / streptomycin, and incubated at 37°C, 5% CO 2 cultured in an incubator. Experiments were performed following the steps of inoculation, transfection, sample application and confirmation. Specifically, CV-1 cells were seeded into a 96-well plate (5000 cells / well), and transfected 24 hours later. Full-length PPAR plasmid DNA, reporter DNA to confirm PPAR activity due to luciferase activity, β-galactosidase DNA to provide information on tran...

Embodiment 3

[0056] Embodiment 3: the preparation of runway material

[0057] (1) with 85 kilograms of formula I polymer, 2 kilograms of N-cyclohexyl-2-benzothiazole sulfenamide, 2 kilograms of amino silicone oil, 3 kilograms of DL-1000, 0.05 kilograms of antioxidant 1010, 0.1 kg of phenyl o-hydroxybenzoate is fully mixed, stirred evenly, and heated to about 90°C;

[0058] (2) add 3 kilograms of talcum powder and 0.5 kilograms of 4.4 '-bis(2.2-dimethylbenzyl) diphenylamine, stir;

[0059] (3) Grinding the above-mentioned materials to a particle size below 400 mesh with a colloid mill;

[0060] (4) Continue to heat up to about 100°C, and dehydrate for 4 hours at a vacuum degree below 0.06MPa.

Abstract

The invention relates to a novel environment-friendly track. The track is prepared from the raw materials in parts by weight: 75-85 parts of polymer, 1-3 parts of padding, 1-2 parts of accelerant, 0.5-0.8 part of anti-aging agent, 2-5 parts of grease, 3-6 parts of polyether polyol, 0.05-0.1 part of antioxidant and 0.05-0.1 part of ultraviolet absorbent. When being formed by a material, the track is good in mechanical property, short in surface drying time and curing time, good in wear resistance, excellent in weather resistance and waterproofness and not prone to aging.

Description

technical field [0001] The invention relates to the field of high molecular polymers, in particular, the invention relates to an environment-friendly plastic runway material and a preparation method thereof. Background technique [0002] Plastic track, also known as all-weather track and field track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports...
