Problems solved by technology

[0002] Train seats are generally made of synthetic leather. Due to the large number of passengers on the train, the seats are in use for a long time, and food etc. often fall on the seats, causing erosion to the seats. Conventional artificial leather is used in The train seat is easy to wear and corrode, and it may cause a fire when encountering an open flame, causing serious casualties

Embodiment

[0018] Embodiment: a kind of high-solid train leather manufacture method, concrete steps are as follows:

[0019] Step 1: Dry Mixing Ingredients:

[0020] a: Mix 80-100kg of high-scratch-resistant polyurethane surface layer resin, 30-60kg of dimethylformamide, 20-40kg of methyl ethyl ketone, 5-10kg of flame retardant, 0.5-2kg of additives and 5-8kg of toner, and then high-speed Stir evenly, and the stirring time is 15 to 20 minutes to prepare a high-scratch-resistant dry-laid fabric, which is filtered and sealed for use;

[0021] b: Stir 80-100kg of polyurethane resin with high solid content, 20-40kg of dimethylformamide, 5-10kg of flame retardant, 0.5-2kg of additives, 5-8kg of toner and 8-20kg of cross-linking agent at high speed , the stirring time is 15-20 minutes, and the middle layer material with high solid content is obtained, which is filtered and sealed for use;

[0022] c: Mix 80-100kg of polyurethane adhesive resin, 20-40kg of dimethylformamide, 20-50kg of methyl...

Abstract

The invention discloses a high-solid-content train leather production method, which comprises the following steps of: evenly agitating high-scratch-resistance polyurethane surface layer resin, dimethylformamide, butanone, flame retardant, assistants and toner to obtain dry-process surface materials; evenly agitating high-solid-content polyurethane resin, dimethylformamide, flame retardant, assistants, toner and cross-linking agent to obtain middle layer materials; evenly agitating polyurethane bonding resin, dimethylformamide, butanone, flame retardant, cross-linking agent and toner to obtain bonding agent; and evenly coating the dry-process surface materials on release paper, drying the release paper to obtain a surface layer dry film, evenly coating the middle layer materials on the surface layer dry film, drying the surface layer dry film to obtain a middle layer dry film, evenly coating the bonding agent on the middle layer dry film, bonding selected bottom fabrics on the surface of the bonding agent, then drying and cooling for formation and finally separating the release paper to obtain the finished product. The high-solid-content train leather production method has the advantages that the process is simple and the production operation is facilitated; and the synthetic leather produced by adopting the production method provided by the invention has the advantages of fire prevention, high scratch resistance, wear resistance and hydrolysis resistance, and can be used as train seat leather.

Description

technical field [0001] The invention relates to a method for making artificial leather, in particular to a method for making high-solid train leather. Background technique [0002] Train seats are generally made of synthetic leather. Due to the large number of passengers on the train, the seats are in use for a long time, and food etc. often fall on the seats, causing erosion to the seats. Conventional artificial leather is used in The train seat is easy to wear and corrode, and it may cause a fire when encountering an open flame, causing serious casualties. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a method for manufacturing high-solid train leather. The high-solid train leather manufacture method has a simple process, and the produced product is fireproof, highly scratch-resistant, wear-resistant, and hydrolysis-resistant. [0004] The technical scheme that the present invention adopts in order to...
