preparation example Construction

[0046] First aspect, the embodiment of the present invention provides a kind of preparation method of antifouling automobile interior fabric, and this preparation method comprises:

[0047] Step 1. Mix silica nano-microspheres, fluorine-containing acrylate copolymer, aqueous isocyanate and water, and stir to obtain a finishing solution.

[0048] Step 2, immersing the automotive interior fabric in the finishing solution, and sequentially rolling, drying, and baking to obtain the antifouling automotive interior fabric.

[0049] Wherein, the mass fractions of silicon dioxide nano-microspheres, fluorine-containing acrylate copolymer, and water-based isocyanate in the finishing solution are 0.2%-1.2%, 1.5%-8%, and 0.1%-0.72%, respectively.

[0050] It should be noted that silica nanospheres are silica particles with a particle size ranging from 5 nanometers to 1000 micrometers.

[0051] It can be seen that the finishing liquid used in the preparation method of the antifouling auto...

Embodiment 1

[0114] The present embodiment provides a kind of antifouling automobile interior fabric, and its preparation method comprises:

Abstract

The invention discloses anti-fouling automobile interior fabric and a preparation method thereof, belonging to the field of automobiles. The preparation method comprises the steps of mixing silica nanospheres, a fluorine-containing acrylate copolymer, water-based isocyanate and water, and stirring to obtain finishing liquid; dipping automobile interior fabric into the finishing liquid, and sequentially rolling, drying and baking to obtain the anti-fouling automobile interior fabric; the mass fractions of the silica nanospheres, the fluorine-containing acrylate copolymer and the water-based isocyanate in the finishing liquid are respectively 0.2-1.2%, 1.5-8% and 0.1-0.72%. The finishing liquid used in the preparation method provided by the invention adopts the fluorine-containing acrylate copolymer as a main waterproof and oil-repellent substance; the water-based isocyanate is used as a crosslinking agent, so that the abrasion resistance of the surface layer of the anti-fouling automobile interior fabric is improved; the silica microspheres are used as a reinforcing component, so that the wear resistance of the anti-fouling automobile interior fabric is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an antifouling automobile interior fabric and a preparation method thereof. Background technique [0002] Automotive interior fabrics are commonly used to upholster car seat covers, seat cushions, headliners, door panels, and more. During the use of the car, the car interior fabric will inevitably come into contact with water, oil and other pollutants, and it is not easy to remove for cleaning, and mildew and other hazards may occur. Therefore, it is necessary to provide a method for preparing an anti-fouling automotive interior fabric, so as to improve the waterproof and oil-repellent performance of the automotive interior fabric. [0003] The prior art provides a method for preparing an antifouling automotive interior fabric, the preparation method comprising: mixing an antifouling finishing agent, a rubbing fastness improving component and water, and stirring to obtain a finishing ...
