Problems solved by technology

[0006] Although the above-mentioned synthetic leather bases have improved the breathable and moisture-permeable properties of polyurethane to a certain extent, with the advancement of science and technology, people's requirements for synthetic leather bases are gradually increasing, and their performance is still not ideal.
And it uses ordinary materials as the base cloth, and there is still a price difference in the strength, modulus, chemical resistance, weather resistance, wear resistance, and puncture resistance of the base cloth. The friction coefficient is large, resulting in short service life and unable to meet some Performance requirements for high-quality products

Abstract

The invention relates to the field of leather making, and discloses a preparation method of a high-strength anti-puncture synthesized leather bass by performing impregnation treatment on UHMWPE fiber three-dimensional compound nonwoven cloth through water-base resin. The preparation method comprises the following steps: preparation of the UHMWPE fiber three-dimensional compound nonwoven cloth, pre-impregnation, primary microwave drying, ironing, main impregnation, secondary microwave drying, washing, microwave drying for the third time and leather grinding, wherein the UHMWPE fiber three-dimensional compound nonwoven cloth is formed by weaving coarse denier UHMWPE fiber yarns, fine denier UHMWPE short fibers and water-soluble short fibers which serve as raw materials; in the main impregnation process, main impregnation liquid contains graphene-modified aqueous polyurethane resin. The synthesized leather bass disclosed by the invention is higher in strength, modulus, specific strength and specific modulus, high in weather resistance, high temperature resistance, chemical resistance and wear resistance, and extremely high in impact strength, can absorb shock impact and prevent noise, is low in friction coefficient, and is high in moisture permeability and breathability, green, environment-friendly, comfortable and low in cost.

Description

technical field [0001] The invention relates to the field of tanning, in particular to a method for preparing a high-strength stab-resistant synthetic leather base made of UHMWPE fiber three-dimensional composite non-woven fabric impregnated with water-based resin. Background technique [0002] Synthetic leather has been widely used in various fields. Synthetic leather base is a semi-finished product of synthetic leather, which is generally formed by wet impregnation of base cloth. Synthetic leather basses can be used to make finished products. Depending on the process, it can be made of suede leather, ordinary synthetic leather, superfiber and so on. [0003] Among them, polyurethane synthetic leather is currently the most widely used synthetic leather. The film-forming material of polyurethane synthetic leather is polyurethane resin. The coating formed by polyurethane resin has the disadvantages of poor moisture permeability and air permeability, and not comfortable enou...
