Embodiment 1

[0032] The proportion of the colorless film mixed slurry by weight is:

[0033] KT254W thermoplastic polyurethane TPU resin 100

[0034] Anti-sticking agent amino-modified polysiloxane of grade T257 0.5

[0035] Dimethylformamide DMF 30

[0036] The viscosity of the prepared mixed slurry is 1800cps / 25℃

[0037] The coating thickness of the colorless film mixed slurry is 15 filaments, and the mixed slurry forms a transparent protective film with a thickness of 5 filaments on the surface of the metal film. The wear resistance is good, but the cost is relatively high. Product wear resistance test results: H18 grinding head 225 revolutions, Martindale grinding 11000 times, the same metal film synthetic leather has not been surface treated by the method of the present invention, and its wear resistance: H18 grinding head 35 revolutions, Martindale Grind 2600 times.

Embodiment 2

[0039] The proportion of the colorless film mixed slurry by weight is:

[0040] KT254W thermoplastic polyurethane TPU resin 100

[0041] Anti-sticking agent amino-modified polysiloxane of grade T257 0.5

[0042] Dimethylformamide DMF 38

[0043] The viscosity of the prepared mixed slurry is 1500cps / 25℃

[0044] The coating thickness of the colorless film mixed slurry is 14 filaments. The mixed slurry can form a protective film with a thickness of 4 filaments on the surface of the metal film, with good wear resistance and moderate cost. Product wear resistance test results: H18 grinding head 180 revolutions, Martindale grinding 90000 times, the same metal film synthetic leather has not been surface treated by the method of the present invention, and its wear resistance: H18 grinding head 35 revolutions, Martindale Grind 2600 times.

Embodiment 3

[0046] The proportion of the colorless film mixed slurry by weight is:

[0047] KT254W thermoplastic polyurethane TPU resin 100

[0048] Anti-sticking agent amino-modified polysiloxane of grade T257 0.5

[0049] Dimethylformamide DMF 45

[0050] The viscosity of the prepared mixed slurry is 1200cps / 25℃

[0051] The coating thickness of the colorless film mixed slurry is 13 filaments. The mixed slurry can form a protective film with a thickness of 2 filaments on the surface of the metal film. The wear resistance is slightly worse than the ratio 1 and the ratio 2, and the cost is low. Product wear resistance test results: H18 grinding head 120 revolutions, Martindale grinding 50,000 times, the same metal film synthetic leather has not been surface treated by the method of the present invention, and its wear resistance: H18 grinding head 35 revolutions, Martindale Grind 2600 times.

Abstract

The invention relates to a superficial treatment process of a high abrasion resistance metallic film synthetic leather, which is characterized that the superficial treatment process comprises the following steps: coating a colorless film on the metallic film surface of the metallic film of the metallic film synthetic leather; thermally sealing a colorless film release paper and the metallic film synthetic leather by using the colorless film and the metallic film; stripping the separated paper after being cooled; and then completing the preparation of the high abrasion resistance metallic film synthetic leather. The invention can not only effectively avoid stripping and surface decoloring, but also improve the product quality.

Description

Technical field [0001] The invention relates to a synthetic leather surface treatment process, more specifically a metal film synthetic leather surface treatment process Background technique [0002] With the development of social economy, people's quality of life is improving day by day. The requirements for the grade and quality of daily necessities are also getting higher and higher. Metal film is used on shoe leather and luggage fabrics, with bright color and strong metallic texture, which is deeply loved by consumers. However, the existing metal film products have poor surface wear resistance, easy peeling, and surface discoloration, which reduces the performance of the product and seriously affects the quality of the product. Summary of the invention [0003] In order to avoid the above-mentioned shortcomings of the prior art, the present invention provides a surface treatment process for high wear-resistant metal film synthetic leather, and provides a manufacturing proces...
