Artificial leather for carbon nano tube reinforced adsorption type environment-friendly automotive upholstery and preparation method thereof

Abstract

The invention discloses artificial leather for carbon nano tube reinforced adsorption type environment-friendly automotive upholstery. The artificial leather is prepared from, by weight, 75-77 parts of polyamide-6, 25-26 parts of alkali-soluble polyester chips, an appropriate amount of a 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 color paste, an appropriate amount of water, 0.7-0.8 part of pregelatinized starch, 2-3 parts of liquid silica gel, 0.7-0.8 part of beta-cyclodextrin, 4-5 parts of carbon nano tubes, 4-5 parts of concentrated sulfuric acid, 0.8-1 part of cocoanut fatty acid diethanolamide and 1-1.2 parts of lignin. The artificial leather utilizes strong acid to conduct surface oxidation on the carbon nano tubes, can strengthen the interface combination effect and compatibility of the carbon nano tubes and polyurethane and improve the strength of a produced product, also has a good adsorption effect and can improve an automotive interior environment after being made into the automotive upholstery.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a carbon nanotube-enhanced adsorption type artificial leather for environment-friendly automotive interior parts 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. T...

AI Technical Summary

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.
