Anti-yellowing type matte wetting and unsmoothing waxy-feel treatment agent for synthetic leather and preparation method thereof

Abstract

The invention relates to an anti-yellowing type matte wetting and unsmoothing waxy-feel treatment agent for synthetic leather. The anti-yellowing type matte wetting and unsmoothing waxy-feel treatment agent is composed of the following components: modified anti-yellowing type polyurethane resin, butanone, toluene, silica extinction powder, polyether modified silicone oil and alkyl sulfonic acid. The invention further relates to a preparation method of the anti-yellowing type matte wetting and unsmoothing waxy-feel treatment agent for the synthetic leather. Compared with the traditional common treatment agent for the synthetic agent, the anti-yellowing type matte wetting and unsmoothing waxy-feel treatment agent for the synthetic leather has a good color development property and a good levelling property, is used to process the surface of the synthetic leather to ensure that the surface of the synthetic leather achieves good matte degree, natural gloss, unique wet / unsmooth hand-feel, delicate and full waxy feel and better anti-yellowing property, and the synthetic leather prepared by using the treatment agent is unique and comfortable in touch feel, good in anti-yellowing effect and excellent in comprehensive effect.

Description

Technical field [0001] The invention relates to a yellowing-resistant matte wet and astringent waxy feel treatment agent for synthetic leather and a preparation method thereof, in particular to a yellowing-resistant matte wet and astringent waxy feel treatment agent for synthetic leather used in the back-end process of synthetic leather And its preparation method. Background technique [0002] At present, synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. Synthetic leather has the characteristics of good physical properties, resistance to tortuosity, flexibility, high tensile strength, and breathability. Therefore, synthetic leather is widely used in footwear fabrics or the weight-bearing parts of luggage. The surface of synthetic leather often needs some surface treatment agents to obtain leather with different performance characteristics. In recent years, as consumers have increasingly higher requirements for the color ...

AI Technical Summary

Problems solved by technology

In recent years, as consumers have higher and higher requirements for the color and feel of the leather surface, for example, the coating layer is required not only to have a good feel, to be comfortable to use, but also to have a smooth feeling, etc., especially to overcome the synthetic The yellowing of leather products under sunlight and air for a long time will seriously affect the beauty of synthetic leather.

[0003] Therefore, the original mature common synthetic leather surface treatment agent can no longer meet the increasing requirements of consumers for aesthetic feeling and hand feeling, and the anti-yellowing type matte wet astringent waxy feeling treatment agent for synthetic leather has not been reported yet.
