Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-aging and hydrolysis-resistant PU synthetic leather fabric and its preparation method, which has the advantage of good hydrolysis resistance and solves the problem of poor hydrolysis resistance of the current PU synthetic leather. It means that the anti-aging ability of leather is not good, so the range of use of leather has been greatly affected, and the application of PU synthetic leather products is limited.

Embodiment 1

[0032] See figure 1 The anti-aging and hydrolysis-resistant PU synthetic leather fabric provided by the embodiments of the present invention includes a base fabric layer 1, a wet polyurethane layer 2, a dry polyurethane layer 3, and an antibacterial layer 4. The wet polyurethane layer 2 is coated on the base fabric layer On the top of 1, the dry polyurethane layer 3 is coated on the top of the wet polyurethane layer 2, the antibacterial layer 4 is coated on the top of the dry polyurethane layer 3, the surface of the antibacterial layer 4 is provided with vents, and the vents penetrate the dry polyurethane Layer 3, wet-process polyurethane layer 2 and base fabric layer 1. Base fabric layer 1 is a micro-fleece with a thickness of 0.8mm, the back of base fabric layer 1 is smooth, and antibacterial layer 4 is leather antibacterial and antifungal agent, and leather is antibacterial and antifungal The agent is formed by chemical reaction of antibacterial macromolecular organic biguan...

Embodiment 2

[0042] The anti-aging and hydrolysis-resistant PU synthetic leather fabric and the preparation method thereof provided by the embodiment of the present invention are basically the same as that of Embodiment 1, and the difference lies in:

[0043] The preparation method of the anti-aging and hydrolysis resistant PU synthetic leather fabric includes the following steps: step one, mixing liquid preparation; step two, preparing wet polyurethane layer emulsion; step three, wet bass production; step four, back treatment; step Five, dry polyurethane layer mixture ingredients; step six, dry veneer treatment; step seven, inspection; among them:

[0044] In step 1, 1.1 parts of 1,4-butenediol, 1 part of heptamethyltrisiloxane and 0.05 parts of catalyst metal platinum were added to the reaction flask, and then 400 parts of toluene were added and nitrogen protection was applied. While stirring, the temperature was raised to 110°C, and the reaction was stirred for 6 hours. After the reaction, t...

Embodiment 3

[0052] The anti-aging and hydrolysis-resistant PU synthetic leather fabric and the preparation method thereof provided by the embodiment of the present invention are basically the same as that of Embodiment 1, and the difference lies in:

[0053] A preparation method of anti-aging and hydrolysis resistant PU synthetic leather fabric, comprising the following steps: step one, mixing liquid preparation; step two, preparing wet polyurethane layer emulsion; step three, wet bass production; step four, back treatment; step Five, dry polyurethane layer mixture ingredients; step six, dry veneer treatment; step seven, inspection; among them:

[0054] In step 1, 1.2 parts of 1,4-butenediol, 1.2 parts of heptamethyltrisiloxane and 0.07 parts of catalyst metal platinum were added to the reaction flask, and then 500 parts of toluene were added and nitrogen protection was introduced. While stirring, the temperature was raised to 120°C, and the reaction was stirred for 7 hours. After the reaction...

Abstract

The invention discloses an anti-aging hydrolysis-resistant PU synthetic leather fabric, which comprises a base cloth layer, a wet polyurethane layer, a dry polyurethane layer and an antibacterial layer, wherein the wet polyurethane layer is coated on the top of the base cloth layer, the dry polyurethane layer is coated on the top of the wet polyurethane layer, the antibacterial layer is coated onthe top of the dry polyurethane layer, and air holes are formed in a surface of the antibacterial layer. The invention also discloses a preparation method of the anti-aging hydrolysis-resistant PU synthetic leather fabric. The synthetic leather produced by the process method has the advantages of being resistant in wear and cold, hard to crack, resistant in solvent, heat and tearing, soft, bright,comfortable in hand feeling and the like, the synthetic leather is good in stability, more environment-friendly, low in cost and high in physical property, and the anti-aging performance of the PU synthetic leather is improved when the super-strong hydrolysis resistance is provided, so that the PU synthetic leather fabric is durable.

Description

Technical field [0001] The invention relates to the technical field of PU synthetic leather, in particular to an anti-aging and hydrolysis-resistant PU synthetic leather fabric and a preparation method thereof. Background technique [0002] PU synthetic leather is a polyurethane elastomer, similar in structure to natural leather, and has the advantages of good appearance and texture, strong mechanical properties, low price, and convenient processing. It has a wide range of applications and a large number of varieties. It is an ideal material to replace natural leather. At present, natural leather with insufficient resources has been replaced in large quantities. However, some of the properties of PU synthetic leather are far inferior to natural leather. For example, natural leather has good water absorption and air permeability, and the nature of PU synthetic leather makes it easy to form a dense film. Water absorption and air permeability are limited, and it is difficult to impr...
