Embodiment 1

[0020] A wear-resistant and scratch-resistant modification method of leather for bags, the specific production process is as follows:

[0021] Step 1: Disperse 5 parts of white carbon black and 1 part of microsilica in 60 parts of ethanol medium, ultrasonicate at 40°C for 2 hours, stir in a water bath at 60°C for 3 hours, then perform suction filtration, vacuum at 60°C Drying to obtain wear-resistant hybrid fillers; after wet blending and modification treatment, the silica particles partially cover the surface of the micro-silica fume and connect the micro-silica particles together, filling the wet-blended silica-micro Silica fume hybrid filler exhibits excellent dispersion and wear resistance in the coating;

[0022] The second step: using hydrochloric acid as the doping acid, using an in-situ polymerization method, using aniline and graphene as raw materials, and ammonium persulfate as an oxidant, to prepare polyaniline-graphene composite anti-scratch fillers with uniform te...

Embodiment 2

[0030] A wear-resistant and scratch-resistant modification method of leather for bags, the specific production process is as follows:

[0031] The first step: wet blending to prepare wear-resistant hybrid fillers:

[0032] Disperse 10 parts of white carbon black and 2 parts of microsilica in 120 parts of ethanol medium, ultrasonicate at 45°C for 1 hour, stir in a water bath at 65°C for 2 hours, then perform suction filtration, and vacuum dry at 65°C to obtain Grinding hybrid filler;

[0033] Step 2: Preparation of anti-scratch filler:

[0034] Add 2 parts of graphene into hydrochloric acid and ultrasonically mix for 2 hours, then add 2 parts of aniline monomer and continue ultrasonication for 40 minutes, add 126 parts of absolute ethanol and 100 parts of water and stir for 25 minutes, slowly drop in 12 parts of ammonium persulfate aqueous solution, at 0 ℃ Stir in an ice-water bath for 6 hours, after standing still, wash with water and suction filter until the filtrate is color...

Abstract

The invention discloses a wear-resistant and scratch-resistant modification method of leather for bags and suitcases. The production process comprises the following steps: (1) dispersing white carbonblack and silicon micro powder in an ethanol medium, carrying out ultrasonic treatment, stirring in a water bath, carrying out suction filtration, and carrying out vacuum drying to obtain a wear-resistant hybrid filler; (2) adding graphene into hydrochloric acid, carrying out ultrasonic mixing, then adding an aniline monomer, continuously carrying out ultrasonic treatment, adding absolute ethyl alcohol and water, stirring, slowly adding an ammonium persulfate aqueous solution in a dropwise manner, stirring in an ice-water bath, standing, washing with water, carrying out suction filtration until filtrate is colorless, and drying to obtain a scratch-resistant filler; and (3) dissolving bisphenol A aniline benzoxazine and an alicyclic epoxy resin in acetone, carrying out ultrasonic oscillation to completely dissolve, adding the wear-resistant hybrid filler and the scratch-resistant filler, carrying out ultrasonic uniform mixing, pouring the obtained mixture into a cleaned spray gun, uniformly spraying the mixture on the surface of cleaned leather at room temperature, and curing to prepare the wear-resistant scratch-resistant coating.

Description

technical field [0001] The invention belongs to the technical field of leather bags, and in particular relates to a method for modifying wear-resistant and scratch-resistant leather for bags. Background technique [0002] Luggage is a general term for bags, and it is a general term for various bags used to hold things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, satchels, waist bags and various trolley cases, etc. . Fabric is the main material of luggage products. Fabric not only directly affects the appearance of the product, but also affects the market price of the product, so it must be given great attention when designing and selecting. There are many kinds of materials that can be used for the fabric of luggage products, and the products are also classified according to different fabrics. [0003] Among them, artificial leather and synthetic leather are the most used. The appearance of artificial leather is similar to natura...
