Leather preparation method and application

Abstract

The invention relates to a leather preparation method. The method comprises the following steps: S101, dissolving graphene in an acid solution; and heating for 3-5h under the temperature of 110-130 DEG C; S102, adding a polyethylene acrylate and tourmaline powder to the product obtained in S101; uniformly stirring, and regulating the pH of the product to be 5.8-6.3; S103, adding polyurethane resin and polyvinyl alcohol to the product obtained in S102; uniformly stirring; S104, coating a base leather with the product obtained in S103, so as to obtain the leather. According to the method, the graphene is used as the additive to be applied to the leather preparation process, so that the obtained leather product, in particular a leather bad mat, is outstanding in abrasion and scratching resisting functions, antistatic function, wave absorbing function, bacteria resisting function, mould preventing performance, UV ageing resisting performance, flame resisting and smoke inhibiting performance, electromagnetic shielding function, infrared healthcare function and other function. Therefore, the level of the leather can be comprehensively increased; the comfort, the durability, the mould resistance and the bacteria resistance of national cattlehide bed mats can be improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a preparation method and application of leather. Background technique [0002] As we all know, graphene is a two-dimensional material formed by carbon atoms arranged in sp2 bonds and a honeycomb lattice. It can extend infinitely in two-dimensional space, and is considered to be the thinnest material in the universe and the strongest s material. Graphene has impenetrability, excellent mechanical properties, transparency, and electrical conductivity, and is considered an ideal material for separation applications. It has become a research hotspot in the fields of physics, chemistry, biology, and materials science. [0003] my country is a big producer of artificial leather and synthetic leather. In recent years, the leather industry has developed rapidly, and leather products are more and more widely used in people's daily life, such as sofas, clothes, and mats and cushi...

AI Technical Summary

Problems solved by technology

(3) Linen mat: moisture-absorbing, breathable, antibacterial, but not cool enough, and too soft, poor flatness

Good toughness, not easy to break, soft and wear-resistant, good elasticity, foldable, long service life, comfortable, cool heat dissipation, sweat-absorbing and non-sticky, not moth-eaten, but the price is higher

(5) Cowhide mat: large heat capacity, good heat dissipation, excellent moisture-proof function, the disadvantage is that the skin feels sticky when sweating, and the price is high

Although the traditional leather mat made of natural leather has the advantages of smoothness, coolness, good water vapor permeability, many appearance changes and durability, it also has disadvantages such as not suitable for washing, easy to decolorize, and troublesome storage and maintenance.

The main hazards of non-compliance with rubbing color fastness: light ones are likely to cause pollution of light-colored clothing, and severe ones are likely to cause the components in the surface coating layer to be absorbed by the human body after contact, thereby affecting human health, and may also directly affect the quality of the product. service life
