Anti-abrasion micro-fiber polyurethane artificial leather suitable for producing automobile-seat fabric and preparing method of anti-abrasion micro-fiber polyurethane artificial leather

Abstract

The invention discloses an anti-abrasion micro-fiber polyurethane artificial leather suitable for producing automobile-seat fabric. The anti-abrasion micro-fiber polyurethane artificial leather is prepared from, by weight, 75-77 parts of polyamide-6, 25-26 parts of alkali-soluble polyester chips, a proper quantity of sodium hydroxide solution with the concentration of 20%, 50-53 parts of waterborne polyurethane, 5-6 parts of nano-magnesium hydroxide, 3-4 parts of ammonium polyphosphate, 5-6 parts of sodium dodecyl benzene sulfonate, 3-4 parts of rutile titanium white paste, a proper amount of water, 0.8-1 part of ethoxylated lauryl alcohol sulfate, 2-3 parts of carbon nano tubes, 3-4 parts of graphite, 4-5 parts of polytetrafluoroethylene latex, 0.8-1 part of silane coupling agent kh550 and a proper amount of ethyl alcohol of 75%. According to the anti-abrasion micro-fiber polyurethane artificial leather, the carbon nano tubes, the graphite and the polytetrafluoroethylene latex are added into the waterborne polyurethane slurry, the synergistic effect is achieved, the strength and the abrasive resistance of the product are enhanced, the product is not prone to abrasion in the using process, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a wear-resistant superfiber polyurethane artificial leather suitable for producing automobile seat fabrics and a preparation method thereof. Background technique [0002] With the rapid development of the economy, people's living standards are getting higher and higher, and the requirements for the quality of life are gradually increasing. The demand for leather products is increasing, and the grade is getting higher and higher. Our country has a large population and few resources, and the source of leather is limited, so it is difficult to meet people's needs. Nowadays, automotive interior leather has been widely used in the interior parts of passenger cars and transport vehicles. With the improvement of living standards, people have higher and higher requirements for the quality, environmental protection and comfort of automotive interior leather. The bes...

Problems solved by technology

Ordinary PVC artificial leather has defects such as hard hand feeling, poor comfort, poor aging resistance, heavy odor, and easy migration and precipitation of plasticizers. Therefore, ordinary PVC artificial leather in automotive interiors has gradually been replaced by polyurethane (PU) synthetic leather. replaced by

The production of polyurethane synthetic leather adopts a solvent-based production system. The use of a large amount of organic solvents not only pollutes the environment, but also seriously damages people's health.
