Abstract

A production method of PU special NU-BUCK leather, which is characterized in that a first layer mixture was coated evenly onthe releasing paper; after oven drying, the surface was coated evenly with second layer of mixture; after oven drying, the surfacewas evenly coated with third layer of mixture; the surface was laminated with a wet-type base cloth and oven dried; after curing,separating the laminate to obtain semi-product; the semi-product wentthrough coarse, fine processing to obtain a PU special NU-BUCK whichhas same visionary, feel, and twisted color change effects as a real NU-BUCK leather.

Description

218901 A6 B6 V. Description of the invention (1) The present invention is related to PU synthetic leather, more specifically, it is a kind of imitation of PU synthetic leather with the same vision, touch and variation as the color-changing cow bag leather The test method of Γ PU special cow bag leather is J. As modern people's living standards are increasingly mentioning ancient men's 4 M b Α 1 β Μ and the improvement of knowledge levels, people's appreciation of daily living items (such as Pi Ping, Gan Shou) Ai's appreciation is also relatively improved, but the natural resources Limited, so people have a tendency to replace synthetic leather with imitation of synthetic leather in Zhejiang. However, as for clinker leather manufacturing method, both jun and users know that PU synthetic leather on the surface can never break the bottleneck π & ~ Ping, the feeling, touch and so-called discoloration test on the leather surface do not have the real Xianshengxing R road and discoloration function, resulting in that PU synthetic leather has not yet widely replaced the leather (cattle ρ > dry bago leather). Achieve the effect of reducing costs and securing natural resources. Β 7 双 '痋 Therefore, for the current defect testing of Ρυ synthetic leather, we are looking for the ideal ^ μ ^ ^ 5 < Today, the above leather manufacturing methods are sincerely international leather manufacturing業 所 許 目 ， 系 向 # 楊 "& waiters strive to improve. In view of the fact that the inventor of the present invention has been carefully researched by Xie Tian Ye Xin, Yi Ji has been engaged in the production and development of the leather chemical industry for many years. 4 After testing, deployment and experiments, he has finally invented a revolutionary 4 A f < Pu synthetic leather resembles cow bago, the "PU special cow bag leather manufacturing method" in the past. That is, the primary objective of the present invention

Description of Invention) As far as I know. The simple diagram of the diagram is shown in Table 1. The formula of the manufacturing method of p U special Φbar · pi to protect the invention is a table of imitation and weight ratio. Chart 2 is the manufacturing method of the PU special cow bago skin of the present invention. Flow chart is attached. Annex 3 is the finished product of the PU special cow bag skin of the present invention. The finished product is better than the car. Example: Shu Xixu Mingmao: First of all, please refer to the chart 1 and it is the formula of the method for manufacturing PU special sister cow bag of the present invention to imitate and weight ratio, in which the formula is divided into three categories: »First Category: Its main imitation protection includes a liquid soap, solvent MEK, fibroin and color material: the temperature-to-temperature ratio of this imitation is about 90 ~ 110: 6β—β0: 5-25: 1 ~ 3 (color (It depends on the increase and decrease of the required skin color). The second category: the main pseudo-type is a color changing resin, MEK, DHF and coloring agent; the temperature-ratio of the Fang imitation is about 90 ~ 110: 10 ~ 30: 5 ~ 15 :; 1 ~ 3 (The color material will increase or decrease depending on the required skin color). The third category: the main 1¾'s include a liquid resin, solvent MEK and color material: the temperature ratio of the imitation is about 1 it ~ 35: 5 p 6 (color material depends on the required skin color Increase and decrease). With the above basic formula and weight * The manufacturing flow of the present invention is described later:. Bu paper size H] China 3 home ίί # (CKS) W regulations 彳 M2U 丨 X 烈?

Description of the invention (3) Please refer to the second chart, the manufacturing flow chart of the manufacturing method of the pu super cow bagopi of the present invention is mainly related to the RP release liner (the surface of the release paper is the pre-selected corrugated texture, 90 Lambskin glycosides, etc.) The surface is evenly covered with the first type of formula, the coating weight is about 100 ... 200 grams per yard, and then the diameter is sent for dry treatment, the temperature is about 100 ~ 1.2R ° C, and the time is about 1 minute 20 Secondly, then uniformly apply the second type of formula on the surface, the coating weight is about 120 ~ 130 grams per yard, and then send the drying process, the temperature is about 1 10 ~ 130 = 0, and the time is about 20 minutes. Finally, evenly apply the third type of formula on the panties, the coating weight is 90 ~ 100 grams, and it is applied to the wet Basel wet Basel'g Jing treatment and dried and then coagulated and then washed, hot Dry curing and pre-drying, then pick it up * The 11 picking products are wet base, half-bun products. After the above two olds are bonded and cooked (that is, obtain the required Surface skin trade pattern), to separate it to obtain an intermediate cliff product, and then send this intermediate product to coarse and fine surface grinding processing, that is, the PU PU-BUCK skin of the present invention is prepared The noodles have the same characteristics as the real cow bag, the touch and the embossing feature have a color-changing function, and the price is for the review of the review committee: the inventor specializes in Annex III of the Ministry of Economic Affairs. The quasi-bureau β industrial consumer cooperative printed one of the PU special cow bag (A) of the present invention, which intercepted and defeated the real cow barge skin, and compared it with the test 15.
