Abstract
The invention relates to a method for producing continuous wide regenerated leather by utilizing leather waste materials to carry out reproduction, in particular to a method for producing the regenerated leather, which comprises the steps of extracting leather broken fibers, soaking, rolling, drying, vulcanizing and surface coating in sequence to produce a continuous wide finished product, wherein the rolling is completed by the steps of stirring and feeding, distributing, heating and dehydrating, extruding and rolling. The invention has simple process flow, low cost, no pollution, continuous and wide product width, excellent quality and wide application range.
Description
Technical field
The present invention relates to a kind of leather waste that utilizes and produce again, manufacture the regenerative leather of continuous wide breadth, specifically a kind of manufacture method of regenerated leather.
Background technology
The manufacture method of present regenerated leather, generally be to utilize tannery, the discarded leftover pieces of Leather Goods Factory, adopt wet manufacturing process, make the skin base, carry out again using after the working procedure processing such as split, mill skin, spraying, embossing, it is made in the technical process of skin base needs a large amount of water, and wherein the water more than 70% is to discharge with waste water formation, and 1 ton of finished product regenerated leather of the every production of this method can be discharged about 80 tons waste water.The cost height of the adhesive that is adopted and other auxiliary agent, in addition, the yield rate of skin base when carrying out split is low, has therefore wasted skin resource and associated materials, has increased labour intensity, and production cost is improved.Because the volume of skin base is little, the utilization rate that the monolithic regenerative leather carries out split processing is low, and the later stage scope of application is limited.
Summary of the invention
The objective of the invention is to solve the deficiency of above-mentioned technology, provide that a kind of technology is simple, cost is low, the manufacture method of the regenerative leather of pollution-free, its applied range, continuous wide breadth.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of manufacture method of regenerated leather, after it is characterized in that process is extraction, immersion, system volume, drying, sulfuration and the top finishing of process leather broken fiber successively, make the finished product of continuous wide breadth.
System volume among the present invention is to comprise the steps:
A, stirring are fed in raw material: soaked hide fiber, natural emulsion and auxiliary materials are put into agitator stir.Its weight proportion is: hide fiber 100, natural emulsion 10-15, auxiliary materials contain sulphur 0.5-2.5, styrenated phenol 0.05-0.2, tetramethylthiuram disulfide 0.8-2.0, dispersing agent MF 0.02-0.08, zinc oxide 0.5-2.0, potassium hydroxide 0.2-0.5, casein 0.3-0.6, acetate 5-10.
B, cloth: the skin blank that will stir is put into the cloth batch can, is placed on the conveyer belt through the even continuous cloth of distributing device, becomes the continuous wide breadth shape.
C, the dehydration of heating: cloth is placed on the skin blank on the conveyer belt, enters heating region under the conveying of conveyer belt, and through the interval of excess temperature at 50 ℃-90 ℃, natural emulsion, auxiliary materials and hide fiber solidify polymerization, isolate moisture.
D, extruding rolling: the cladding that the polymerization of heating is good enters the drum-type compression roller through conveyer belt, passes through under the pressure of 150Mpa-220Mpa, and rolling after the compression moulding enters next drying process.
The present invention has the following advantages: with adopt conventional wet to make regenerative leather to compare, technological process is simple, cost is low, 1 ton of finished product regenerative leather of every production in the production process, water consumption is original 1/5th.The industrial chemicals of cold way residual many in water, it is residual that the present invention does not have industrial chemicals.Cold way latex accounts for 50% of total amount, the present invention only need its 1/4th.The regenerative leather that the present invention makes, best in quality, it is strong, high temperature resistant, wear-resisting etc. to have hygroscopicity, gas permeability, flexibility, pulling force, have the characteristics of corium and PU concurrently, price only is 1/10th of a corium, three times of PU, be the discarded back environment-friendly products of degraded easily, do not produce secondary pollution in process of production, product becomes continuous wide breadth, applied range.
The specific embodiment
Embodiment 1: a kind of manufacture method of regenerative leather, after it passes through extraction, immersion, system volume, drying, sulfuration and the top finishing of leather broken fiber successively, make the finished product of continuous wide breadth.
Undertaken by following operation successively:
1, the extraction of leather broken fiber: with the waste leather material sorting, pulverize, therefrom extract hide fiber with pulverizer.
2, soak: hide fiber and a certain amount of water are put into pond immersion 30-40 minute.
3, system volume: soaked hide fiber, natural emulsion and auxiliary materials are put into agitator, hide fiber 100, natural emulsion 10-15, auxiliary materials contain sulphur 0.5-2.5, styrenated phenol 0.05-0.2, tetramethylthiuram disulfide 0.8-2.0, dispersing agent MF 0.02-0.08, zinc oxide 0.5-2.0, potassium hydroxide 0.2-0.5 by weight ratio, casein 0.3-0.6, acetate 5-10 feed in raw material for it, stir; The skin blank that stirs is put into the cloth batch can, be placed on the conveyer belt, become the continuous wide breadth shape through the even continuous cloth of distributing device; Cloth is placed on the skin blank on the conveyer belt, enters heating region under the conveying of conveyer belt, and through the interval of excess temperature at 50 ℃-90 ℃, natural emulsion, auxiliary materials and hide fiber solidify polymerization, isolate moisture; The cladding that the polymerization of heating is good enters in the drum-type compression roller through conveyer belt, passes through rolling after the compression moulding under the pressure of 150Mpa-220Mpa.
4, drying: the coiled material after the compression moulding, drying is 2 hours under 50 ℃ temperature.Can in hothouse, carry out, but also natural drying.
5, sulfuration: dried coiled material enters vulcanizing chamber, and sulfuration is 24 hours in the curing cage of 80 ℃ of temperature.
6, top finishing: to the coiled material that vulcanizates polish, hot pressing, spraying, make the finished product coiled material.
Above-mentioned operation has pollution-free, low energy consumption, high-quality characteristics, and the regenerative leather of its manufacturing can form the leather of continuous wide breadth, and is best in quality, performance good, applied range.
