Abstract

The invention discloses suede type styrene-butadiene segmented copolymer-based superfine fiber synthetic leather and a production method thereof, and relates to the technical field of superfine fibersynthetic leather. The preparation method comprises the following steps of infiltrating and compounding a styrene-butadiene segmented copolymer material and a sea-island fiber non-woven fabric base material in a curtain coating and extruding manner to obtain a composite material; treating the obtained composite material through a steam alkali deweighting technology to obtain a styrene-butadiene segmented copolymer / superfine fiber composite material; and carrying out an after-finishing process on the obtained styrene-butadiene segmented copolymer / superfine fiber composite material to obtain thesuede-type styrene-butadiene segmented copolymer-based superfine fiber synthetic leather. The production process is clean and environmentally friendly, the obtained product is soft and full in hand feeling, the atomization value is smaller than 4 mg, the smell is smaller than the third level, the product can be used as a vamp material and has good bonding strength with an SBS injection molding sole, and the product can be used for producing high-performance anti-skid sneakers and can also be used as an environment-friendly skin material of automobile seats.

Description

Technical field[0001]The present invention belongs to the field of ultrafine fiber synthesis leather, and it is related to a velvet type styrene-butadiene block copolymer microfiber synthesis and its production methods.Background technique[0002]Due to limited raw skin resources used to produce natural leather, and natural leather production is a high energy consumption, high pollution process will bring great pollution load to the environment. In recent years, people have also proposed new standards for the safety of natural leather itself, strictly restricting CR (VI), azo dyes, pentachlorophenol (PCP) and free formaldehyde in natural leather. Toxic chemicals. From the perspective of raw skin resources, environmental protection, product safety and market, natural leather production and use are facing great challenges.[0003]Based on the above reasons, all countries in the world are accelerating new materials replacing natural leather. Among them, the development of ultrafine fiber s...
