preparation example Construction

[0038]In the preparation process of the polymer fabric, the polymerization reaction is carried out in a high-pressure reactor after drying and filling with nitrogen, and the pressure is preferably controlled at 9.9-10.1 MPa. The molar ratio of the silsesquioxane derivatized propylene oxide, propylene oxide and initiator is 1:5~25:0.001~0.002, preferably 1:10~20:0.001~0.002, more preferably 1: 10-15: 0.001-0.002. The mass ratio of the double metal cyanide complex to the mixture is 200-300 mg / kg. The initiator is one or more of propylene glycol, ethylene glycol, glycerol trimethylolpropane, pentaerythritol, xylitol, sorbitol, sucrose, diethylamine and diethylenetriamine.

[0039] The present invention carries out spinning and spinning in ether steam and steam, and the schematic diagram of the process is as attached figure 2 As shown; the overall shape of the spinneret is circular, and the spinneret looks down as attached image 3 As shown, there are 45 to 50 nozzles on each ...

[0049] In the rapidly stirred 100mL zinc chloride-water-tert-butanol (10g zinc chloride, 75mL water, 25mL tert-butanol) mixed solution, gradually drop 20mL potassium hexacyanocobaltate-water-tert-butanol mixed solution ( 24.5g potassium hexacyanocobaltate, 15mL water, 5mL tert-butanol), about 100min to complete the dropwise addition, continue the reaction for 100min, control the temperature of the reaction process at 50°C; separate the white precipitate formed by the reaction by centrifugation (8000r / min) , were washed three times with 20 mL of tert-butanol-water mixed solution, and dried in vacuum at 50 °C for 10 h to obtain a white block DMC catalyst.

[0050] The propylene oxide derivatized by silsesquioxane according to the molar feeding ratio: propylene oxide: ethylene glycol = 1: 10: 0.001 is fed into the high-pressure reactor after the dry nitrogen-filled treatment, and 250 mg of catalyst DMC is added per kilogram of feeding , control the pressure at 10±0.1MPa, control ...

[0054] Prepare the adsorbent, the weight ratio is as follows: silica gel: diatomaceous earth: activated carbon: molecular sieve = 3: 15: 80: 5; fill the evenly mixed adsorbent into the linen bag, and sew the linen bag around tightly after filling. The final thickness of the odor absorption layer is 1.05cm; the odor absorption layer is attached to the sponge layer and the mesh layer with Velcro, and the thickness of the sponge layer is 1cm; then the new polymer woven layer is bonded to the mesh layer with waterproof glue, The amount of waterproof glue is calculated according to the area of ​​the fabric 1L / m 2 , The gluing method is manual gluing, and after gluing, it is air-dried at room temperature and bonded. The finished product can be obtained by air drying at room temperature. The waterproof glue was purchased from Shanghai Suao Chemical Co., Ltd., model SA-1002.

Abstract

The invention provides a method for preparing a polymer fabric and an automobile ceiling fabric for removing odor and preventing mold in an automobile. A polymer fabric layer adopts a piece of polymer woven cloth with a silsesquioxane side chain, and the overall solubility of polyether is changed by silsesquioxane on the side chain, so that the polymer fabric layer is not soluble in water and has high molecular weight polymers with good mechanical strength. As a polymer framework is not soluble in ether but is soluble in water, and the polymer side chain is soluble in ether but is not soluble in water, silsesquioxane functional groups on the polymers are easy to accumulate at an outer polymer fiber layer obtained through ejection spinning, and as moisture is wrapped with an inner layer, micropore gaps are formed through dehydration in a later drying process, and the obtained polymer fabric is good in air permeability and very poor in water absorption. Besides, an absorbing layer is relatively good in odor removal and water removal effect, so that the dryness of the automobile ceiling fabric is effectively maintained, the odor in the automobile is removed, and the automobile ceiling fabric is prevented from rot or mold.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for preparing car roof fabrics and polymer fabrics for removing peculiar smell and preventing mildew in cars. Background technique [0002] Cars, as an indispensable means of transportation in modern life, have been very popular in recent years. However, the car space is a typical closed environment, and various peculiar smells are unavoidable over time. Now some big brand cars have adopted a certain technology to make the car interior worse for the adsorption of peculiar smell, which is conducive to the discharge of peculiar smell under the condition of ventilation. But this is not a good method, especially in winter and summer, car owners usually close the windows to ensure a comfortable temperature inside the car. In order to remove the peculiar smell in the car, various car air fresheners have been launched on the market, but these air fresheners are all chemica...
