In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment, as shown in fig. 1, the utility model provides a pair of prevent that water separates resistant alcohol synthetic leather, include first base cloth layer 1, first thick liquids layer 2, second base cloth layer 3, second thick liquids layer 4, fire-retardant layer 5 and the waterproof layer 6 that sets gradually from bottom to top, be provided with one deck silk screen layer 7 between first thick liquids layer 2 and first base cloth layer 1, the second base cloth layer 3 respectively. The flame-retardant layer 5 and the waterproof layer 6 can respectively enable the product to have good flame retardance and waterproof and alcohol-resistant performances; the first slurry layer 2 and the second slurry layer 4 can be made of polyurethane materials, and are distributed with the two base fabric layers at intervals, so that a silk screen layer and the two base fabric layers form a good combination, and a good bonding effect is achieved; meanwhile, the strength of the product can be improved on the premise of ensuring the flexibility of the product by adding the silk screen layer, so that the service life of the whole product is prolonged.

Specifically, each mesh layer 7 includes a first carbon fiber mesh layer 71, a metal mesh layer 72, and a second carbon fiber mesh layer 73. The carbon fiber is a novel fiber material of high-strength and high-modulus fiber with the carbon content of more than 95 percent. The carbon fiber is flexible outside and rigid inside, has lighter weight than metal aluminum, but higher strength than steel, and has the characteristics of corrosion resistance and high modulus. It not only has the intrinsic characteristic of carbon material, but also has the soft workability of textile fiber, and is a new generation of reinforced fiber. The wire mesh layer 72 has good ductility and strength. In this way, the use of two carbon fiber mesh layers and one wire mesh layer provides the device with relatively high structural strength while providing flexibility.

Further, the wire mesh layer 72 used in the present apparatus is a mesh woven from nickel alloy wires. The nickel alloy is an alloy formed by adding other elements on the basis of nickel. The nickel has good mechanical, physical and chemical properties, the oxidation resistance, corrosion resistance and high-temperature strength of the nickel alloy can be improved by adding proper elements, and certain physical properties of the nickel alloy can be improved.

In order to improve the waterproof performance of the product, the waterproof layer 6 of the present invention includes a modified polyurethane layer 61 and a wax layer 62 modified with organic siloxane. Among them, the modified polyurethane layer 61 is a layer in which water resistance is greatly improved by introducing organosiloxane into a polyurethane segment. This is because the silica segment has strong hydrophobicity, the average chain length between adjacent crosslinking points in the system is shortened by the hydrolysis crosslinking reaction therein, and the linear molecules of the crude oil are changed into network-shaped molecules by the crosslinking action, thereby further improving the water resistance of the polyurethane layer. The wax light layer 6 is arranged on the surface of the modified polyurethane layer to protect the appearance part of the whole product and has good waterproof performance.

In order to improve the artificial leather effect of the product, the modified polyurethane layer 61 is provided with patterns; meanwhile, on the premise of ensuring good flame retardance and waterproofness of the product, the total thickness of the flame-retardant layer 5 and the waterproof layer 6 is smaller than that of the first base fabric layer 1, the first slurry layer 2, the second base fabric layer 3 and the second slurry layer 4, and the first base fabric layer, the first slurry layer, the second base fabric layer and the second slurry layer play a main role in the whole product.
