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
The present invention relates to a kind of artificial leather preparation method, particularly a kind of high solid leather for trains preparation method.
Background technology
Train chair generally adopts synthetic leather to make; because the passenger is more on the train; seat is in the use state for a long time; and often having food etc. on the seat drops on the seat; seat is produced erosion; conventional leatheret uses at train chair and is easy to wearing and tearing, corrosion is bad, but runs into also fire hazard of naked light, causes serious injures and deaths.
Summary of the invention
In order to overcome defects, the invention provides a kind of high solid leather for trains preparation method, the solid leather for trains preparation method technique of this height is simple, the product fire prevention of producing, high scratch resistance, wear-resisting, hydrolysis.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of high solid leather for trains preparation method, and concrete steps are as follows:
Step 1: dry mixed batching:
A: high-speed stirred after high scratch resistance polyurethane surface layer resin 80～100kg, dimethyl formamide 30～60kg, butanone 20～40kg, fire retardant 5～10kg, auxiliary agent 0.5～2kg and the toner 5～8kg mixing is even, mixing time 15～20 minutes, make high scratch resistance dry method fabric, the filtration sealing is stand-by;
B: polyurethane resin 80～100kg, dimethyl formamide 20～40kg, fire retardant 5～10kg, auxiliary agent 0.5～2kg, toner 5～8kg and crosslinking agent 8～20kg high-speed stirred of high solids content is even, mixing time 15～20 minutes, make the middle material of high solids content, the filtration sealing is stand-by;
C: high-speed stirred after polyurethane binder resin 80～100kg, dimethyl formamide 20～40kg, butanone 20～50kg, fire retardant 5～10kg, crosslinking agent 8～15kg and the toner 5～8kg mixing is even, mixing time 10～15 minutes, make the adhesive with good degree of cross linking, the filtration sealing is stand-by;
Step 2: choose release liners and base fabric;
Step 3: dry method veneer:
The high scratch resistance dry method fabric for preparing evenly is coated on the release liners of choosing dries, baking temperature is 100～140 ℃, make the surface layer dry film, on the surface layer dry film, evenly apply again the middle material of high solids content, then oven dry, bake out temperature is 120～160 ℃, make the middle level dry film, then on the dry film of middle level, evenly apply the adhesive with good degree of cross linking, stick the base fabric of choosing at adhesive surface again, dry under 120～145 ℃ of conditions through baking oven, then cooling forming finally separates namely getting high solid leather for trains with release liners;
Step 4: check, packing:
Gained finished product in the step 3 checked according to test stone and the packing case of packing in.
As a further improvement on the present invention, speed of production is in the described step 3: 4～8 m/mins.
As a further improvement on the present invention, in the described step 2 release liners with the flower type.
As a further improvement on the present invention, mixture all mixes in the reactor that can take out negative pressure in the described step 1.
The invention has the beneficial effects as follows: technique of the present invention is simple, is convenient to production operation, and the synthetic leather that uses process of the present invention to produce has the advantage of fire prevention, high scratch resistance, wear-resisting, hydrolysis, is applicable to train chair with removing from office.
