Abstract

The invention provides a manufacturing method of high-temperature-resistant and flame-retardant PU (polyurethane) leather and solves technical problems that sofa leather prepared with a conventional preparation method cannot be used in a complicated environment and has single usability and the like due to absence of flame retardant property. The manufacturing method of the high-temperature-resistant and flame-retardant PU leather comprises following steps: a, selection of a base layer: commercially available cattlehide or sheepskin in the market is selected as the base layer, and the base layer is cut into a rectangular shape by a cutting device; b, coating of a PU layer: one side surface of the base layer is coated with the PU layer in a spraying manner by means of a leather spraying device; c, coating of a flame retardant layer: the other side surface of the base layer is coated with the flame retardant layer by means of the leather spraying device; d, compounding: a fabric layer is compounded on the other side surface of the PU layer by a compounding machine, and existing warp knitted fabric commercially available in the market is adopted as the fabric layer. The manufacturing method of the high-temperature-resistant and flame-retardant PU leather has the advantage of high practicability.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a manufacturing method of high-temperature-resistant and flame-retardant PU leather. Background technique [0002] Sofa leather is the main raw material for making leather sofas. There are many raw materials for sofa leather on the surface of sofas, including genuine leather sofa leather, PU sofa leather, PVC shoe upper leather, etc. Leather sofa leather generally has cowhide, pigskin, and horsehide. Cowhide is divided into yellow cowhide and buffalo leather, which are divided into first layer, second layer and third layer according to their layers. The sofa is made of soft leather. It is better to have a large area of ​​sofa leather, which can increase the cutting rate and reduce seams. There is a kind of leather called modified leather. Modified leather is processed and painted on the leather surface, and it can be pressed with different textures. Some painted leather materials are t...
