Problems solved by technology

[0004] The technical problem mainly solved by the present invention: the surface of the common car floor leather is generally not high in wear resistance, and the phenomenon of surface wear and tear often occurs, and it is easy to separate and warp along the edge after water seepage during use, which directly affects service life, and the traditional floor leather is directly bonded and laid on the floor of the car with solvent glue, and a large amount of toxic and harmful organic solvents volatilize into the car when spraying glue, and the smell is extremely unpleasant. Organic solvents will continue to volatilize and become an important source of organic volatile gases in the car, seriously affecting the air quality in new cars and directly endangering the health of passengers, and the fact that most floor leathers

[0030] Add 11g of antimony chloride and 0.4g of polyethylene glycol to 250mL of absolute ethanol, ultrasonically disperse for 15min until completely dissolved, then transfer to a 500mL three-necked flask with a stirrer and dropping funnel, and drop 11mL of 0.5mol / L ammonium fluoride solution, and adjust the pH to 9 with ammonia water with a mass concentration of 5%, to obtain a mixed solution; transfer the above mixed solution into a water bath, heat up to 35°C, and start the stirrer to stir at a constant temperature for complexation reaction After 2 hours, the reactant was poured into a Buchner funnel, and the filter residue was obtained by suction filtration. The filter residue was put into a vacuum drying oven at 83° C. to dry to constant weight and then ground to obtain white nano antimony trioxide powder; weigh 8 g of the above-prepared Disperse nano antimony trioxide powder into 80mL deionized water, add 2g aliphatic amine polyoxyethylene ether, stir evenly with a glass r...

Abstract

The invention relates to a preparation method of adhesive coating, wear resistant and flame resistant floor leather for a vehicle, and belongs to the field of floor leather preparation. The preparation method lies in that melamine resin-coated nanometer antimony trioxide is taken as a fire retardant, silicon carbide micro powder is taken as an antiwear filler, through processes such as tanning and hot pressing, finally the adhesive coating, wear resistant and flame resistant floor leather for the vehicle is prepared by being sequentially coated with a hot-melt pressure-sensitive adhesive and an isolating membrane layer, wherein as melamine resin-coated nanometer antimony trioxide is taken as a flame resistant material, the fire resistance is greatly improved, silicon carbide micro powder is hot pressed on the leather surface, and the floor leather surface abrasion resistance is also improved; besides, due to use of the hot-melt pressure-sensitive adhesive, the harm to a human body caused by an organic solvent in the solvent adhesive is avoided, and therefore the floor leather is excellent in comprehensive performance, and has a broad application prospect.

Description

technical field [0001] The invention relates to a preparation method of adhesive-coated wear-resistant and flame-retardant vehicle floor leather, which belongs to the field of floor leather preparation. Background technique [0002] At present, there are many kinds of automobile floor leather on the market, such as linen floor leather, rubber floor leather, plastic floor leather, three-dimensional floor leather and so on. Although it can play the role of dustproof, waterproof and mudproof to varying degrees, and protect the carpet in the car, but in the process of use, the floor leather itself is easy to hide dirt, dirt, and breed bacteria, and the material will age, become thinner, and deform. , produce peculiar smell and other situations, making it difficult to achieve a clean and beautiful environment in the car, which is not good for human health. Moreover, the surface of the traditional artificial leather is easy to wear and tear. In the use of products such as floor l...
