Preparation method of adhesive coating, wear resistant and flame resistant floor leather for vehicle

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...

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 have poor flame retardancy provides a Nano antimony trioxide coated with melamine resin is used as a flame retardant, and silicon carbide micropowder is used as a wear-resistant filler. After tanning, hot pressing and other processes, a hot-melt pressure-sensitive adhesive is applied and an isolation film is finally applied to prepare a coating. Rubber wear-resistant and flame-retardant automotive floor leather, in which melamine resin is coated with nano-antimony trioxide as a flame-retardant material to greatly improve its flame retardancy. wear resistance, the use of hot-melt pressure-sensitive adhesives avoids the harm to the human body caused by the organic solvents in the solvent glue, so that the floor leather of the present invention has excellent comprehensive performance and has broad application prospects
