Description

A kind of high abrasion-proof PU artificial leather and its preparation process
Technical field
The present invention relates to artificial leather fields, more specifically to a kind of high abrasion-proof PU artificial leather and its preparation process.
Background technique
PU artificial leather is exactly the epidermis of polyurethane composition.It is widely used in making the dress of luggage, clothes, shoes, vehicle and furniture Decorations, it has increasingly obtained the affirmative in market, and application range is wide, and quantity is big, as many as kind, be traditional natural leather without What method met.Its quality of PU artificial leather also has quality, and good PU artificial leather is even also more expensive than corium price.Exploitation at the beginning of the sixties Kind be made using nylon loop as base using polyurethane solutions of coating.Nylon loop polyurethane solutions dipping is coated and is passed through Water-bath solidification after resulting microporous layers, after flour milling polyurethane suede leather.This artificial leather quality is light and soft, it is wear-resisting, warming, Feel is not influenced by cold and Warm Changes in Northern, is suitable for production clothes, higher packet, bag and adornment.
Existing market at present, is widely used more common Polyurethane Leatherette technology, solid content 30 or so percent, And solvent accounting 70 or so percent, because solvent usage amount is big, the more harmful to human of solvent remaining quantity and environment, it is odor profiles compared with Greatly.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, one of the objects of the present invention is to provide a kind of high abrasion-proof PU artificial leather, It may be implemented to reduce solvent usage amount, the effect of solvent remaining quantity, to reduce this PU artificial leather to the danger of human body and environment Evil, odor profiles excellent, low VOC, while this PU artificial leather have high-wearing feature, moisture absorption, ventilative, fire-retardant, high durable, purification air Etc. functions.
Another object of the present invention is to provide the preparation processes of above-mentioned high abrasion-proof PU artificial leather.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that.
A kind of high abrasion-proof PU artificial leather, including main structure layer, it is wear-resisting that main structure layer upper end is successively arranged reinforcement Layer, wearing layer, surface layer, anion layer and moisture absorption layer, the reinforcement wearing layer are connect with main structure layer, the reinforcement wearing layer One end far from main structure layer is connect with wearing layer, and the wearing layer is connect far from one end of reinforcement wearing layer with surface layer, institute Surface layer to be stated to connect far from one end of wearing layer with anion layer, the anion layer is connect far from one end of surface layer with moisture absorption layer, Following layer and base cloth layer are successively arranged below the main structure layer, the base cloth layer is weaved by the full terylen line of high physical property in length and breadth It forms, the full terylen line is hollow structure, is filled with polyester fiber, the following layer and main structure in the full terylen line Layer connection, the following layer are connect far from one end of main structure layer with base cloth layer, and the moisture absorption layer upper surface is connected with antibacterial Antibiotic layer, the bacteriostasis antibiosis layer surface do sanding processing and form pro-skin villus, and it is residual that reduction solvent usage amount, solvent may be implemented The effect of storage, so that harm of this PU artificial leather to human body and environment is reduced, odor profiles excellent, low VOC, while this PU is artificial Leather has the function of high-wearing feature, moisture absorption, ventilative, fire-retardant, high durable, purification air etc..
Further, the moisture absorption layer and anion layer are all made of aqueous polycarbonate, and albumen is added in the moisture absorption layer Matter raw material, after aqueous polycarbonate and protein raw material are carried out mixed processing, so that moisture absorption layer is given moisture absorbing, it is described Anion material is added in anion layer, after aqueous polycarbonate and anion material mixed processing, so that anion layer is assigned The function of air purification function is given, while the anion material in anion layer can dispel free radical, have to body-care Good effect, while can be with deodorization and sterilization.
Further, the surface layer uses aqueous polycarbonate resin surface treating agent, for reducing solvent in inorganic agent Content, while improving odor profiles.
Further, the wearing layer and reinforcement wearing layer are all made of polycarbonate resin while environment-friendly type of arranging in pairs or groups is wear-resisting Bubble is eliminated through accurate defoaming device and promotes compactness, and then increases wearability by agent, the setting of dual wearing layer, so that this The wearability of PU artificial leather is significantly improved.
Further, the main structure layer uses the solid content polyether resin of two-liquid type 95 or more percent, warp Bubble elimination is promoted compactness by accurate defoaming device, is kept fluid,matching stability with thermostat, is dried and generate through high temperature Space network reaches the effect of low VOC, low smell to reach buffering effect, to reduce product solvent content, and simultaneously With high durable.
Further, the following layer uses aqueous polyethers two-liquid type resin, so that the content and gas of fitting base fabric solvent Taste is not easy to increase.
Further, the moisture absorption layer, anion layer, surface layer, wearing layer, reinforcement wearing layer, main structure layer, following layer With base cloth layer before production fitting, in one layer of base fabric layer surface spray attachment environmentally friendly phosphorus flame retardant, so that phosphorous flame-retardant layer is formed, This PU artificial leather is set to be endowed flame retarding function.
Further, the semi-finished product of described PU artificial leather are handled with physics gas permeable devices, have product ventilative Function.
Further, the material of the bacteriostasis antibiosis layer is bamboo cotton fiber, and bamboo cotton fiber has the effect of bacteriostasis antibiosis, is pressed down Bacterium antibiotic layer can make this PU artificial leather, and bacteria can be prevented from growing, increases safety.
The preparation process of above-mentioned high abrasion-proof PU artificial leather, comprising the following steps:
Protein raw material is added in the first step in aqueous polycarbonate, and the two progress mixed processing is then obtained moisture absorption Layer；
In aqueous polycarbonate and anion material is added in second step, then by the two progress mixed processing obtain bearing from Sublayer；
Third step handles surface layer with aqueous polycarbonate resin surface treating agent；
4th step, with polycarbonate resin and collocation environment-friendly type anti-wear agent, through accurate defoaming device by bubble eliminate promoted Compactness obtains wearing layer, and then increases wearability, then one layer of reinforcement wearing layer is arranged in the same way；
5th step, with the solid content polyether resin of two-liquid type 95 or more percent, through accurate defoaming device by bubble Elimination promotes compactness, keeps fluid,matching stability with thermostat, dries through high temperature and generates space network to reach buffering Effect, to form main structure layer；
6th step, using aqueous polyethers two-liquid type resin as following layer so that the content of fitting base fabric solvent and odor profiles It is not easy to increase；
7th step weaves to form base cloth layer by the full terylen line of high physical property in length and breadth；
Product obtained in 8th step, the first seven step is before production fitting, first with one layer of ring of special spraying equipment back side spray attachment It protects phosphorus flame retardant and forms phosphorous flame-retardant layer, this PU artificial leather is made to be endowed flame retarding function；
9th step, the semi-finished product for completing the first eight step, are handled with physics gas permeable devices, product are made to have airing function.
