Abstract
The invention relates to the technical field of synthetic leather, in particular to leather applicable in the fields of clothing, footwear, furniture, surface decoration, packaging and the like. The leather is composed of environment friendly paper-based composite polyurethane (PU) coatings. The obtained environment friendly leather has the advantages that the leather is toxic-free, recyclable and easily degradable; more particularly, the leather is subjected to the oxidation decomposition in a short time and returned to the nature within the natural environments of sun light, ultraviolet light and exposure to sun and rain, thus avoiding the gas generation or water pollution; moreover, the leather product has the advantages of simple structure, easy fabrication and low fabrication cost, dispenses with the foaming process and achieves the effects of energy conservation and emission reduction, so the invention is of significant social and economic benefits and is favorable for promoting the development of social environmental protection and protecting the human living environment.
Description
Technical field:
The present invention relates to technical field of synthetic leather, refer in particular to the leather in fields such as can be applicable to dress ornament, footwear, furniture, incrustation, packing.
Background technology:
At present, mostly the synthetic leather that the market occurs is to adopt the PU resin of organic solvent type to make as basic unit and surface layer, promptly obtains the PU leather; Such PU resin makes with solvent polymerization method as solvent by toluene, dimethylbenzene, acetone, butanone, ethyl acetate, dimethyl formamide etc., and these organic solvents are all harmful substance, process generation at the synthetic PU leather of foaming has harmful gas, influence healthy, and harmful substance also can be discharged by water and air, serious environment pollution, the feature of environmental protection is poor.In addition, well-known, present PU leather is difficult to degraded, discards at occurring in nature, and the time of staying is long, forms poisonous rubbish, gives people's production, life, the public's life and health formation significant threat.
Development along with human civilization society, various circles of society progressively strengthen the consciousness of environmental protection, various environment-friendly products also appear in the market thereupon, as No. 01136182.4 patent of China, a kind of environmental protection paper is proposed, the not only recyclable utilization of this environmental protection paper, and discard under natural environment, with regard to the energy oxidation Decomposition, return the earth in short time, can not produce poison gas or polluted source.
Under this background, the spirit that the applicant is adhering to the research innovation, keeping on improving is utilized its professional eye and professional knowledge, works out the labile environmental protection leather of a kind of environmental protection.
Summary of the invention:
The object of the present invention is to provide a kind of is base material with environmental protection paper, reaches easy decomposition, reduces the environmental pollution that production process causes, the environmental protection leather that product is nontoxic.
For achieving the above object, the present invention adopts following technical scheme:
A kind of environmental protection leather, this leather are to be made of environmental protection paper base material compound polyurethane paint.
Described polyurethane coating is combined on the face of environmental protection paper base material by casting or blade coating, and is provided with adhesive between environmental protection paper base material and polyurethane coating.
Also be bonded with the fabric layer of reinforcement on the described environmental protection paper base material.
Described polyurethane coating can be one or more layers on the face of environmental protection paper base material, can comprise basic unit and chromatograph during multilayer.
Environmental protection leather provided by the invention has nontoxic, recyclable utilization again, labile advantage; Under sunlight, ultraviolet ray and the large natural environment that exposes to the sun and rain, will oxidation decomposition in the short time, return the earth, do not produce poison gas or polluted source.
Further advantage of the present invention is simple in structure, makes easily, need not foam process, and cost of manufacture is low, reaches effect energy-conservation, that reduce discharging, has social benefit and economic benefit highly, helps to promote the development of social enviroment protection cause, the protection human residential environment.
Description of drawings:
Accompanying drawing 1 is an one example structure schematic diagram of the present invention;
Accompanying drawing 2 is its two example structure schematic diagram of the present invention.
The specific embodiment:
The present invention will be further described below in conjunction with accompanying drawing:
A kind of environmental protection leather of the present invention, this leather are to be made of environmental protection paper base material 1 compound polyurethane paint 2; Polyurethane coating 2 is combined on the face of environmental protection paper base material 1 by casting or blade coating, and is provided with adhesive 3 between environmental protection paper base material 1 and polyurethane coating 2.Wherein, polyurethane coating 2 can be one or more layers design on the face of environmental protection paper base material, can comprise basic unit and chromatograph during multilayer, increases the leather surface pleochroism, improves gloss.
During making, the environmental protection paper of choosing corresponding size size and thickness is as base material 1, and environmental protection paper is No. 01136182.4 described synthetic paper of patent of China, but the market buying.Polyurethane coating 2 is compounded on the face of environmental protection paper base material 1 by casting or blade coating technology then, constitutes the surface layer of leather, also generate lines on the polyurethane coating 2 as required, to obtain the multi-configuration item leather.Before polyurethane coating 2 is compound, compound position at environmental protection paper base material 1 also is coated with adhesive 3, as reactive adhesive, to strengthen the composite force between polyurethane coating 2 and the environmental protection paper base material 1, so that can not split after solidifying, compound tightr, life of product is longer, the surface layer difficult drop-off of leather.
Accompanying drawing 1 is depicted as one example structure schematic diagram of the present invention, behind the selected environmental protection paper base material 1, the side was coated with adhesive 3 thereon before this, and then on the basis of adhesive 3 compound polyurethane paint 2, make polyurethane coating 2 and environmental protection paper base material 1 compound formation leather, also generate lines on the polyurethane coating 2 as required.This synthetic leather is simple in structure, makes easily, and the PU leather with respect to traditional need not foam process, and cost of manufacture is low, reaches effect energy-conservation, that reduce discharging, has social benefit and economic benefit highly; And the environmental protection leather that obtains is nontoxic, recyclable to be utilized again, easily decomposes; Under sunlight, ultraviolet ray and the large natural environment that exposes to the sun and rain, will oxidation decomposition in the short time, return the earth, can not form Harmful Waste, do not produce poison gas and polluted source.
Environmental protection leather provided by the invention is the innovation of carrying out revolution from environmental angle, to have solved the existing not environmental issue of PU leather of traditional use, effectively promotes the development of synthetic leather.This environmental protection leather can be applicable to fields such as dress ornament, footwear, furniture, incrustation, packing, and is nontoxic, pollution-free, effectively protects the human residential environment, is beneficial to people's life and health development.
