Problems solved by technology

[0002] At present, the artificial leather used in my country's truck tarpaulins is made of polyester staple fiber fabrics, which are made of plastic coating. Due to the unreasonable selection of base fabric materials and the shortcomings of the plastic coating method and formula process, PVC rubber is used in the base fabric. Rolling on cloth, rolling, plasticizing, and process production, resulting in artificial leather with many glues, heavy weight, unstable quality, waste material, low strength, rough surface, narrow surface width, easy aging, and short life. Meet the requirements of railway standards

Embodiment

[0045] 1. Preparation of PVC glue

[0046] ①According to the components and weights listed below, weigh them in turn and simply mix the components in an appropriate container for stirring:

[0047] Component Weight (kg)

[0048] 1. PVC paste resin 100

[0049] 2. Flame retardant system

[0050] Antimony trioxide (Sb 2 o 3 ) 5~50

[0051] Phosphate Triester 5~80

[0052] 3. Plasticizing system

[0053] Octyl phthalate (DOP) 5D~20D

Abstract

An artificial dual-surface leather is prepared by coating plastics on both surfaces of high-strength chemical fibre fabric. Its preparing process includes preparing PVC mucilage containing flame retardant, plasticizer and stabilizer, feeding cloth, immersing, rolling levelling, baking, plasticizing and winding.

Description

technical field [0001] The invention relates to a method for producing artificial leather, in particular to the manufacture of high-strength chemical fiber-coated plastic-coated double-sided artificial leather for railway wagon tarpaulins. Background technique [0002] At present, the artificial leather used in my country's truck tarpaulins is made of polyester staple fiber fabrics, which are made of plastic coating. Due to the unreasonable selection of base fabric materials and the shortcomings of the plastic coating method and formula process, PVC rubber is used in the base fabric. Rolling on cloth, rolling, plasticizing, and process production, resulting in artificial leather with many glues, heavy weight, unstable quality, waste material, low strength, rough surface, narrow surface width, easy aging, and short life. Meet the requirements of railway standards. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the e...
