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.

Embodiment 1

[0026] Under normal temperature and pressure, put 12 parts by weight of methyl ethyl ketone, 7 parts by weight of toluene, 4 parts by weight of silica matting powder, and 55 parts by weight of modified yellowing-resistant polyurethane resin into a 1L reactor, and fully stir at least at room temperature. After 30 minutes of grinding, filter and discard the filter residue; add 1 part by weight of polyether modified silicone oil and 1 part by weight of alkyl sulfonate to the resulting mixture, and stir uniformly at room temperature; then add the remaining modified yellowing resistant polyurethane After 20 parts by weight of the resin is uniformly stirred at room temperature for at least 30 minutes until the viscosity is stable, the finished product of the anti-yellowing type matte wet waxy feeling treatment agent for synthetic leather without precipitation and colorless viscous liquid is obtained. The performance indexes of the obtained anti-yellowing type matte wet waxy feeling tr...

Embodiment 2

[0029] Under normal temperature and pressure, put 15 parts by weight of methyl ethyl ketone, 10 parts by weight of toluene, 4 parts by weight of silica matting powder, and 50 parts by weight of modified yellowing-resistant polyurethane resin into a 1L reactor, and fully stir at least at room temperature. After 30 minutes of grinding, filter and discard the filter residue; add 0.5 parts by weight of polyether modified silicone oil and 0.5 parts by weight of alkyl sulfonate to the resulting mixture, and stir uniformly at room temperature; then add the remaining modified yellowing resistant polyurethane After 20 parts by weight of the resin is uniformly stirred at room temperature for at least 30 minutes until the viscosity is stable, the finished product of the anti-yellowing type matte wet waxy feeling treatment agent for synthetic leather without precipitation and colorless viscous liquid is obtained. The performance indexes of the obtained anti-yellowing type matte wet waxy fee...

Embodiment 3

[0032] Under normal temperature and pressure, put 14 parts by weight of methyl ethyl ketone, 8 parts by weight of toluene, 4.5 parts by weight of silica matting powder, and 50 parts by weight of modified yellowing-resistant polyurethane resin into a 1L reactor, and fully stir at least at room temperature. After 30 minutes of grinding, filter and discard the filter residue; add 0.8 parts by weight of polyether modified silicone oil and 0.7 parts by weight of alkyl sulfonate to the resulting mixture, and stir uniformly at room temperature; then add the remaining modified yellowing resistant polyurethane After 22 parts by weight of resin, uniformly stirred at room temperature for at least 30 minutes until the viscosity is stable, the finished product of anti-yellowing type matte wet waxy feeling treatment agent for synthetic leather without precipitation and colorless viscous liquid is obtained. The performance indexes of the obtained anti-yellowing type matte wet waxy feeling trea...

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 ...
