Odor-adsorption automotive interior imitation leather material and preparing method thereof

Abstract

The invention discloses an odor-adsorption automotive interior imitation leather material which is prepared from raw materials: by weight, 75-77 parts of polyamide-6, 25-26 parts of alkali-soluble polyester chips, an appropriate amount of sodium hydroxide solution 20% in concentration, 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 dioxide mill base, an appropriate amount of water, 0.7-0.8 part of ammonium stearate, 3-4 parts of nano-zinc oxide, 2-3 parts of sodium silicoaluminate, 3-4 parts of Binchotan, 1-1.2 parts of polyvinyl pyrrolidone, and 0.3-0.5 part of N,N'-Methylene-bis(acrylamide). As Binchotan, nano-zinc oxide and the like are added into waterborne polyurethane, a slurry prepared by foaming technique is of micropores and micro-holes, and the product has touch as leather, has excellent absorption capacity and is capable of adsorbing odor in cars to purify air in the cars.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a self-adsorbing odor-absorbing imitation leather material for automobile interior decoration 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 best choice for ...

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 Therefore, ordinary PVC artificial leather in automotive interiors has gradually been replaced by polyurethane (PU) synthetic leather.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.
