The manufacturing process of artificial leather has three types of coating processing, calendering processing and cutting processing. Polyurethane (P〇lyurethane, 人造 artificial skin is the most commonly used process for coating processing. The PU resin and the solvent are mixed into a paste, and then uniformly coated on the base, and then vulcanized by the south temperature to obtain the PU artificial leather. Polyvinyl chloride 2olyvinyi chl〇ride, PVC) The most commonly used process for artificial leather is the processing. After the PVC resin and the plasticizer are gelled by a kneading/kneading device, they are pressed into a sheet by a calender. The base fabric is laminated to obtain pvc artificial leather. Window thermoplasticity The most commonly used process for thermoplastic polyurethane (TPU) artificial leather is extrusion processing. The τρυ is gelled by a single lion or twin-screw extruder. The y τ class is formed into a sheet, and then The cloth is laminated to produce τρυ artificial leather (such as Taiwan Patent Publication No. 00442392). The application of artificial leather products is very extensive, and artificial leather can be seen in automobile interiors, leather bags, leather cases, leather bags, clothing, shoes and other products. The main materials are most common with ρυ, PVC and TPU. 200905033 However, the hydrolysis resistance of pu artificial leather is poor. It is easy to react with water to break the molecular chain, which causes yellowing, which causes troubles in application. In addition, pu artificial is made by cross-linking reaction, and its product is not conducive to recycling. use. However, although the process of TPU artificial leather has no cross-linking reaction and hydrolysis resistance is better than that of human skin, TPU artificial leather still has hydrolysis problems, and TPU is expensive, and the market acceptance is low based on cost considerations. Due to the low price of PVC, easy processing, good physical properties, etc., the application history of pvc artificial leather has been very long, but pvc itself contains halogen, and it needs to add plasticizer (such as o-benzate) and heavy metal. The stabilizers, when pvc is used for landfill, have environmental problems of plasticizers and heavy metal pollution. When the waste is incinerated, problems such as "dioxins" are also generated, which causes great troubles in disposal. In recent years, environmental protection issues have gradually received attention. At present, products such as polyolefin elastomer (p〇ly〇lefm elast〇mer, POE) artificial leather (Taiwan Patent Publication No. 1277680) and thermoplastic elastomers have been replaced in the market. (thermoplastic elastomer, TPE) artificial leather. POE artificial leather itself has no polarity, and it is difficult to adhere to the base fabric, surface treatment, and printing. It must be specially treated (such as corona treatment, primer coating), and the POE's recovery elasticity and touch are not as good as Pvc. TPE artificial leather applied on the restricted second-eye field, the material is styrene-butadiene-styrene copolymer (styrene_butadiene_clear copolymer, SBS), ethylene-vinyl acetate copolymer (ethylene) -vinyl-acetate copolymer, EVA), styrene-ethylbmylene-styrene blek copolymer (SEBS), etc., and its products are only attached to the base fabric. A layer of unfoamed soft plastic film is combined, so it has a poor touch. Taiwan Patent Publication No. 1227186 is a foam manufacturing method for TPE composites, but there is only one layer of foamed material on the product and process, and there is no base fabric attached thereto, and 7 200905033 and the use of bridging agent in the material, after bridging The material is special, because its physical properties will be read low; in addition, it takes 10 to 30 minutes, obviously the time is too long, and the average of the artificial leather is only needed for ~5 minutes. [Summary of the Invention] There are artificial skin spots such as PU, TPU, PVC, P0E, TPE, etc., the present hair_providing - (four) styrene hybrid artificial skin and preparation skin = pass (four) Cheng Lai County styrene hybrid artificial leather, The tooth has the advantages of easy adhesion to the base fabric, easy surface treatment and printing, good touch and recyclability. The polyphenylene styrene elastomer is used as a substrate, and the composite material comprises 50~l〇〇phr, processing oil 1〇~1〇〇phr, foaming ^1〇phr, antioxidant ai~5phr, polyolefin polymerization 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 5 5 5 5 5 5 5 5 5 5 5 5 5 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合The artificial leather, the main material is mature polystyrene, the price is cheap, easy to obtain, and its raw material is v-polar, which is quite common in printing and subsequent application. (4) In terms of polystyrene polymer, the polystyrene polymer is not suitable for processing by a calendering process, and the polymer of the polyethylene polymer has poor fluidity and poor heat resistance. If the fluidity is not good and it is pressed into a film or sheet by a calender, the surface will be concave and the flatness will be poor, and the force σ process will also have a problem of uneven accumulation of the wheel, = broken. The present invention utilizes the tempering oil 'and, if necessary, the polyurea poly&' to adjust the proper fluidity of the compound. During calendering, the rubber must be continuously mixed at high temperature, and sometimes it is necessary to enter, ', and 30, so it is easy to cause the poly-S chain to break and change color when the rubber is insufficient. The deep 'further creates a sticky wheel and cannot be subsequently added. Therefore, the present invention adds an appropriate antioxidant to improve the heat resistance of the polymer processing process of the polystyrene 200905033. ^The polystyrene elastomer artificial skin of the present invention does not add a bridging agent, because after the thermoplastic polymer is bridged, just like the thermosetting plastic after curing reaction, it can no longer be reshaped by heating and melting, and the physical property after recycling is greatly Reduced, and not fully environmentally friendly. The polystyrene copolymer used in the present invention may be SBS, styrene-butadiene copolymer (SBC), SEBS or benzene.
