Embodiment Construction

[0045] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0046] Such as Figure 1-3 As shown, the present invention provides a kind of technical scheme: a kind of production process of modified flame-retardant antibacterial PU synthetic leather, comprises the following steps:

[0047] S1. Acid treatment and alkali treatment: immerse the polyester base fabric in the acid treatment solution at a temperature of 70-80°C for 15-20 minutes, then dry it in vacuum at 90-95°C, and then immerse the treated polyester base fabric in In the alkali treatment solution, the temperature is 75-85°C, and the treatment time is 30-40 minutes. After treatment, it is washed with water and dried to constant weight.

[0048] S2. Modified flame retardant: immerse the polyester base fabric treated in S1 in the flame retardant solution at a temperature of 25-35°C, and a treatment time of 80-100min. After treatment, dry it, and the...

Abstract

The invention discloses a modified flame-retardant antibacterial PU synthetic leather production technology and a modified flame-retardant antibacterial PU synthetic leather manufacturing facility, and belongs to the technical field of synthetic leather. A flame retardant is added to PU synthetic leather, halogen series flame retardants which are harmful to a human body and the atmosphere are abandoned, and therefore the purposes that no harmful smoke is generated, and the pollution to the environment is reduced are achieved. Meanwhile, three groups which are in good combination with leather collagen exist in the flame retardant, and therefore the combination between the flame retardant and leather fibers can be firm and reliable, and the stability and the durability of the flame retardingeffect are enhanced. When the PU synthetic leather is coated, an antibacterial agent is added, and therefore the antibacterial agent can act on the PU synthetic leather for a long time through the slow release effect of a microcapsule, an antibacterial protection layer is formed on the surface of the PU synthetic leather, non-toxic and harmless raw materials are adopted by the antibacterial agent, the harm of the antibacterial agent to the human body is reduced under the condition that the antibacterial effect is guaranteed. In this way, the PU synthetic leather can have the flame-retardant and antibacterial effects and is convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, in particular to a modified flame-retardant and antibacterial PU synthetic leather production process and preparation equipment thereof. Background technique [0002] As a type of polyurethane elastomer, PU synthetic leather has the appearance, feel and mechanical properties similar to natural leather. It is currently the most popular and mainstream product in synthetic leather. Fiber components and synthetic leather additives such as protein binders, lignocellulose fillers, etc. provide maple nutrients for the growth of microorganisms, making polyurethane synthetic leather extremely vulnerable to microbial erosion and deterioration, greatly shortening the service life. At the same time, the growth and reproduction of pathogenic microorganisms on the surface will seriously threaten the health and safety of users. In order to increase the service life and safety of polyurethane syntheti...
