Problems solved by technology

[0004] At present, the Yangbuck synthetic leather for shoes sold in the market has a rough feel, insufficient softness, and poor imitation. After post-treatment, although the feel can be changed, it will also damage the leather. The hair is long and the wear resistance of the yangbuck is not ideal, it is easy to scratch and scratch, the waterproof performance is poor and it is difficult to clean

Embodiment 1

[0020] A novel water-repellent superfiber superfine sheepskin leather, the preparation method of which comprises the following steps:

[0021] 1) Configure the coating slurry, dry-coat the base material with the prepared coating slurry, bond the coated base material with the fiber bass, peel off the base material after drying and cooling, and roll the finished product Pick;

[0022] 2) configure yangbuck treatment slurry, and coat one layer of yangbuck treatment slurry on the surface of the finished product obtained in step 1), and the coating thickness of the yangbuck treatment slurry is 25-30g / meter;

[0023] 3) Foaming the finished product treated in step 2) at a temperature of 170-180° C. to obtain a foamed sheepbuck leather sample;

[0024] 4) Carry out kneading and printing processing on the sheepskin leather sample obtained in step 3) to obtain the required sheepskin finished product. During the kneading treatment, the temperature is controlled at 60±5° C.;

Embodiment 2

[0029] In this example, a new type of water-repellent superfiber superfine lambskin is provided, and its preparation method is the same as that of Example 1. The difference between it and Example 1 is that:

[0030] The surface layer slurry coated in step 1) contains 80 parts of polyurethane, 38 parts of DMF, 18 parts of MEK, 5 parts of fluorine-containing silicone oil, 2 parts of animal fat leather fatliquoring agent, and 1 part of silicone leveling agent in parts by weight , with a viscosity of 3200mPa.s (50 modulus); the middle layer slurry contains 80 parts of polyurethane, 32 parts of DMF, 15 parts of MEK, 5 parts of fluorine-containing silicone oil, 2 parts of animal fat leather fatliquor, and silicone fluid in parts by weight. 1 part of leveling agent with a viscosity of 4600mPa.s (30 modulus); the bottom layer slurry is calculated in parts by weight, including 100 parts of polyurethane, 20 parts of DMF, 10 parts of MEK, 5 parts of fluorine-containing silicone oil, and 2...

Embodiment 3

[0033] In this example, a new type of water-repellent superfiber superfine lambskin is provided, and its preparation method is the same as that of Example 1. The difference between it and Example 1 is that:

[0034] The surface layer slurry coated in step 1) contains 90 parts by weight of polyurethane, 35 parts of DMF, 15 parts of MEK, 5 parts of fluorine-containing silicone oil, 2 parts of animal fat leather fatliquor, and 1 part of silicone leveling agent , with a viscosity of 3400mPa.s (50 modulus); the middle layer slurry contains 90 parts of polyurethane, 30 parts of DMF, 13 parts of MEK, 5 parts of fluorine-containing silicone oil, 2 parts of animal fat leather fatliquor, and silicone fluid in parts by weight. 1 part of leveling agent, the viscosity is 4700mPa.s (30 modulus); the bottom layer slurry is calculated in parts by weight, including 100 parts of polyurethane, 20 parts of DMF, 10 parts of MEK, 3 parts of fluorine-containing silicone oil, and 2 parts of animal fat...

Abstract

The invention discloses a preparation method of novel waterproof microfiber superfine yangbuck leather. The preparation method of the novel waterproof microfiber superfine yangbuck leather comprises the following steps of (1) preparing a coating slurry, dry-coating a base material through the prepared coating slurry, laminating the coated base material and fiber besleer, stripping the base material after drying and cooling, and reeling a finished product; (2) preparing a yangbuck treatment slurry, and coating a layer of yangbuck treatment slurry on the surface of the obtained finished product;(3) carrying out yangbuck foaming on the finished product treated through the step (2) at the temperature ranging from 170 to 180 DEG C, and obtaining a foamed yangbuck leather sample; and (4) graining and printing the yangbuck sample obtained by the treatment of the step (3), and obtaining a required yangbuck leather finished product. The yangbuck leather prepared by adopting the preparation method provided by the invention is dustproof and waterproof, has good oil resistance and wear resistance, and is not easy to scratch.

Description

technical field [0001] The invention relates to the technical field of superfine fiber synthetic leather, in particular to a method for preparing a novel water-repellent superfiber and superfine lambskin leather. Background technique [0002] With the improvement of living standards, people's demand for leather products is gradually increasing. However, due to the small quantity and high price of genuine leather products, it cannot meet the increasing needs of people. At present, artificial leather products include luggage, clothing, shoes, etc., and their surface There are various shapes, and the effect styles are varied: high-gloss and high-solid, oily skin style, polished style, crazy horse discoloration, yangbuck, etc. Whether it is in surface effect, feel, or physical quality of the product, it is still Constant pursuit of imitation leather effect. [0003] Yangbuck resin has occupied a large proportion in the leather market in recent years. It uses high temperature ex...
