The technology doesn't adopt DMF agent, so it has not harm to human and environment.
Description
Technical field
The present invention relates to a kind of leather class material and manufacturing technique thereof, particularly relate to a kind of polyolefin leatheroid and manufacturing technique thereof.
Background technology
Commonly use the lining and the foaming layer of polyolefin leatheroid and all made by PU (polypropylene ester plasticizing polymerization thing) material, its manufacturing technique is: the base cloth impregnation is extracted-barrier coating-oven dry foaming-coating surface layer and oven dry-surface treatment.This lining and foaming layer are by PU, and impregnation and coating surface layer and bottom all need be used DMF (toluene, dimethyl formamide) solvent, and DMF all has harm to human body and environment, and its finished product PU leather can not degraded by natural environment, and environmental pollution is comparatively serious.
Summary of the invention
The object of the present invention is to provide that a kind of light weight, low temperature flexibility are good, more folding, the better polyolefin leatheroid of feel.
Another object of the present invention is to provide a kind of more environmental protection, to the manufacturing technique of the littler polyolefin leatheroid of process operation personnel's injury.
For achieving the above object, technical solution of the present invention is:
A kind of polyolefin leatheroid of the present invention, it is made up of base cloth, foaming layer and surface layer; Foaming layer covers on the base cloth, surface layer covers in the foaming layer; Described foaming layer component is (weight portion): TPO (TPO) 90-110, blowing agent 2-4, stabilization agent 2-4, colorant 1-5; Described surface layer component is (weight portion): polyurethane (TPU) 90-110, stabilization agent 0-2, colorant 1-5.
Stabilization agent in the described foaming layer is the metallic soap class, and blowing agent is Celogen Az or azodiisobutyronitrile.
Stabilization agent in the described surface layer is metallic soap class or metallic lead class.
Stabilization agent in described foaming layer and the surface layer is chromium stearate or barium stearate or zinc stearate.
A kind of manufacturing technique according to above-mentioned polyolefin leatheroid, its processing step is as follows: base cloth use resin impregnation 5-15 second; Extract and enter drying oven, dry 40-80 second down at 120-140 ℃; Base cloth applies TPO (TPO) sticker, sends into drying oven oven dry 20-40 second again; On adhering machine, paste TPO (TPO) foaming layer; Apply TPO (TPO) sticker in TPO (TPO) foaming layer, send into drying oven oven dry 20-40 second again; On adhering machine, paste polyurethane (TPU) surface layer; Send into foaming machine and under 200-220 ℃ of temperature, foam 50-70 second, and embossing; Carry out surface treatment at last.
A kind of base cloth impregnation prescription of the manufacturing technique according to the said polyolefins artificial leather is (weight portion): water 90-110, water-base resin 5-15, catalyst 1-3, softener 5-10, dispersant 1-3, bleeding agent 1-3, colorant 1-5.
Described water-base resin is water-soluble polyamine fat, and catalyst is a zinc nitrate, and softener is a N-methylol stearmide, and dispersant is condensation of sodium silicate or calgon or sodium lignin sulfonate, and bleeding agent is sulfonated oil or soybean lecithin mercaptan.
Also comprise defoamer 0-2 in the described prescription.
Described defoamer is phthalic acid diethyl ester or tbp.
After adopting such scheme, because the foaming layer and the surface layer of polyolefin leatheroid of the present invention adopt TPO (TPO) and polyurethane (TPU) material respectively, the polyolefin leatheroid that this material is made has that light weight, low temperature flexibility are good, more folding, the better advantage of feel.And manufacturing technique of the present invention, because the impregnation in the process and coating surface layer and bottom be all without the DMF solvent, solvent-free volatilization can not work the mischief to environment and human body, has environmental protection, the advantage little to process operation personnel's injury.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
