Wear-resistant flame-retardant automotive floor leather and preparation method thereof

Abstract

The invention discloses wear-resistant flame-retardant automotive floor leather. The wear-resistant flame-retardant automotive floor leather is characterized by consisting of a fiber cloth base layerand a wear-resistant flame-retardant surface adhesive layer, wherein the wear-resistant flame-retardant surface adhesive layer is prepared from the following raw materials in parts by weight: 20-30 parts of 2,4-diamino-6-vinyl-S-triazine / 1-adamantyl methacrylate / 3,4,5-trifluorocinnamic acid copolymer, 8-15 parts of hyperbranched polyurethane acrylate, 50-60 parts of 3,5-di(6-isocyanate hexyl)-2H-1,3,5-oxadiazine-2,4,6(3H,5H)-triketone / 1,3-dihydroxy ethyl adamantane polycondensate, 3-5 parts of epoxy modified hexamethylene tetramine, 1-3 parts of black phosphorus, 10-15 parts of nano boron fibers, 1-3 parts of diamond, 1-3 parts of coupling agent, 3-6 parts of amino modified polysiloxane and 0.2-0.4 parts of azodiisobutyronitrile. The invention also discloses a preparation method of the wear-resistant flame-retardant automotive floor leather. The wear-resistant flame-retardant automotive floor leather disclosed by the invention is good in wear-resisting property, remarkable in flame-retardant effect, excellent in environment protection property and antibacterial property, light in weight, high in mechanical strength, good in aging resistance and weather resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of floor leather, in particular to a wear-resistant and flame-retardant vehicle floor leather and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the progress of society, people's living standards have improved year by year, and cars have gradually become the standard equipment for successful people. It not only brings convenience to people's travel, but also a symbol of status. A good horse should be equipped with a good saddle, a good boat should be equipped with a good sail, and a good car should be equipped with good interior decoration materials. This is especially true for floor leather as a common interior decoration material. It is not only required to have excellent wear resistance, but also to be flame retardant, thereby improving its service life and ensuring the personal safety of passengers. [0003] Car floor leather is a new...

AI Technical Summary

Problems solved by technology

However, the flame retardant performance of the floor leather in the prior art is not ideal, and it will burn quickly after encountering an open flame, which cannot effectively delay the spread of the fire, and has a great potential safety hazard

Moreover, the surface of the traditional artificial leather is easy to wear and tear. In the use of products such as floor leather and pedals of car lights, it needs to be replaced frequently, and the cost of use is high. Repeated replacement brings a lot of trouble to users.

[0004] In addition, automotive floor leathers generally have a single-layer or double-layer structure. These floor leathers are prone to breakage, deformation, and aliasing. After water seepage, it is also easy to produce the phenomenon of separation and warping along the edge, which directly affects the service life

[0005] The existing patent document CN 108948577 A discloses an environmentally friendly flame-retardant floor leather and its production method. It is a floor leather specially used for vehicles and has certain flame-retardant properties. The wear-resistant layer is combined through bonding between the layers, which obviously reduces the strength and wear resistance of the floor leather; the existing patent document CN105019256 A discloses a flame-retardant, wear-resistant and non-slip composite floor leather and its manufacturing process It has a good flame retardant effect, but adding phosphorus and halogen flame retardants to the floor leather can be flame retardant, but it will release harmful gases at high temperatures, which will also cause great harm to the human body.
