preparation example Construction

[0033] Specifically, the preparation method of the fullerene polymer comprises the following steps: mixing N-(5-indenyl)-5-norbornene-2-carboxamide and C in a molar ratio of 5 to 10:1 60 Dissolve in 1,2,4-trichlorobenzene, heat and reflux for 12 to 13 hours, then pour into methanol to precipitate, filter with suction and wash the precipitate with methanol to obtain a reaction crude product, dissolve the reaction crude product in toluene, and use Adsorbed on silica gel, and then separated and purified with toluene and n-hexane with a volume ratio of 1:9 as the eluent to obtain a fullerene macromonomer, the 1,2,4-trichlorobenzene and C 60 The volume-to-mass ratio is 40-50mL / 1g, and the heating and reflux temperature is greater than 214°C; the fullerene macromonomer and norbornene are dissolved in toluene, Grubbs catalyst is added, and the reaction is carried out at room temperature for 2 hours. Vinyl ether is added to terminate the reaction, and then ether is used for precipitat...

[0045] Synthesis of Fullerene Macromers

[0046] First, dissolve the solid mixture of 0.74g sodium borohydride and 1.87g precipitated sulfur in 50mL dry tetrahydrofuran to obtain sodium thioborohydride solution, then add 5-nitroindene solution in tetrahydrofuran (1g / 5mL) to keep the reaction The mixture was stirred at room temperature for 16 hours.

[0047] Water was then slowly added to the reaction system, and the reaction liquid was extracted three times with 10 mL of ether, and the organic phases were combined, and the organic phases were washed with 10 mL of distilled water and 10 mL of saturated brine.

[0048] The unstable 5-aminoindene was not isolated, but a freshly prepared 5 mL solution of 5-norbornene-2-formyl chloride in dichloromethane (1.17 g of 5-norbornene-2-carboxylic acid in 6 mL of oxalyl chloride was refluxed 5h, rotary evaporation to remove oxalyl chloride) was directly dropped into the solution of 5-aminoindene, and then 1.1 mL of acid-binding agent tri...

[0054] Synthesis of fullerene polymers

[0055] Dissolve 0.97g of the fullerene macromonomer prepared in Example 1 and 9.41g of norbornene in 20mL of toluene, add a catalytic amount of Grubbs catalyst, react at room temperature for 2h, add vinyl ether to terminate the reaction, and then carry out the reaction with ether Precipitate to obtain 10.01 g of a purple-black solid, with a yield of 96.4%, that is, a novel polymer with fullerene functional groups hanging on the side chain, GPC=32.5kD, M ‾ w / M ‾ n = 1.21 .

[0056] Among them, the 1st and 2nd layers are bonded with waterproof magic stickers, and the 2nd and 3rd layers are bonded with waterproof glue.

[0057] The waterproof glue was purchased from Shanghai Suao Chemical Co., Ltd., model SA-1002.

[0058] The amount of waterproof glue is calc...

Abstract

The invention provides a car roof composite electronic fabric. The car roof composite electronic fabric comprises a cloth layer, a negative ion generating layer and a sponge layer from top to bottom in sequence. A negative ion generator is integrated in the car roof fabric, and a spray point is embedded in a novel fullerene polymer. Resistance of the fullerene polymer is extremely low, and when charges pass through the material, very strong resonance effect is generated for extremely facilitating free separation of electric ions, and therefore, negative ions which are great in dose, high in purity, high in activity and small in grain size can be activated and generated by only needing weak current; by virtue of the good forming performance of the polymer, the spray point can be effectively packaged by using a fullerene functional group, so that release efficiency of the negative ions is improved. Therefore, the car roof composite electronic fabric provided by the invention greatly increases generating efficiency of air negative ions, but also does not generate negative products such as superoxide, nitride and radiation, and the like; meanwhile, integral outline of interior car environment is not affected. The invention further provides the fullerene polymer and a preparation method thereof.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a car roof composite electronic fabric, a fullerene polymer and a preparation method thereof. Background technique [0002] With the improvement of living standards, cars have gradually changed from a luxury means of transportation to a common household equipment. The environment inside the car is a relatively closed environment, and the air quality in the closed environment is generally poor, which can easily cause headaches, dizziness and other uncomfortable symptoms. Negative oxygen ions can effectively activate oxygen molecules in the air, making them more active and more easily absorbed by the human body, and the negatively charged negative ions will neutralize the positively charged smoke and dust in the air, allowing them to deposit naturally, thus effectively greatly improve the air quality of closed environments. [0003] The vehicle-mounted negative ion generator i...
