[0044] refer to Figure 1-3 , a method for preparing artificial synthetic leather containing nitrogenous titanium dioxide, comprising the following steps:

[0045] S1. Unloading: After the base material passes the inspection, it is put on the machine for pre-production preparation.

[0046] S101. Preparation of raw materials;

[0047] S102. Raw material inspection, checking whether the physical parameters of raw materials meet the design requirements;

[0048] S103, mixing ingredients, batching according to the formula, and compounding the fabric layer and the intermediate material respectively;

[0049] S104, filtering, filtering the prepared materials;

[0050] S105, film bubbles, fabric defoaming;

[0051] S106. Coating production, one coating and one drying, four coatings;

[0052] S107. Prepare the surface treatment agent, add 25-30% nitrogen-containing titanium dioxide liquid to the water-based surface treatment agent, and stir the prepared surface treatment agent b...

Embodiment 2

[0067] refer to Figure 1-3 , a method for preparing artificial synthetic leather containing nitrogenous titanium dioxide, comprising the following steps:

[0068] S1. Unloading: After the base material passes the inspection, it is put on the machine for pre-production preparation.

[0069] S101. Preparation of raw materials. The raw materials include PU resin, stabilizer, crosslinking agent, other additives, color paste and nitrogen-containing titanium dioxide. The nitrogen-containing titanium dioxide is one of powder and liquid;

Abstract

The invention belongs to the technical field of artificial synthetic leather, particularly relates to a preparation method of nitrogen-containing titanium dioxide artificial synthetic leather, and provides the following scheme aiming at the problems that existing silver ions cannot be used for people allergic to silver, cannot be metered too much and are harmful to human bodies, the aging time is only 90 days, and the protection time is short, the method comprises the following steps: S1, discharging: after a base material is qualified by inspection, carrying out preparation before production on the base material on a machine; S101, preparing raw materials; and S102, inspection of raw materials. The method can be applied to automobile interior seats and door plates and can also be applied to public fitness equipment back cushions, seat coating leather, public bike cushions, public seats and large traffic and transportation tool seats, auxiliary work is carried out when part of epidemic prevention disinfection work has careless omissions, meanwhile, the disinfection procedure is simplified, and the influence on environment and human health caused by overuse of disinfection liquid medicine is reduced.

Description

technical field [0001] The invention relates to the technical field of artificial synthetic leather, in particular to a method for preparing artificial synthetic leather containing titanium dioxide nitrogen. Background technique [0002] Silver ions are positively charged cations that are formed by electron transfer through chemical reactions and usually exist in aqueous solution. Its solution is colorless and transparent without any solid particles. Silver is one of the trace elements in human tissues. Trace amounts of silver are harmless to the human body. According to the fourth edition of the "World Health Organization Guidelines for Drinking Water Quality" recently released by WHO, drinking water with a concentration of silver ions lower than 0.1ppm is not safe. It will cause adverse effects on the human body (ppm is an expression of the solute mass fraction of a solution, and there is 1 mg of solute in 1 liter of aqueous solution, g / m3 or mg / L). [0003] It has been ...
