Natural leather powder added high-breathability automotive interior decoration leather and preparation method thereof

Abstract

The invention discloses natural leather powder added high-breathability automotive interior decoration leather. The automotive interior decoration leather is characterized by being prepared from, by weight, 75-77 parts of polyamide-6, 25-26 parts of alkali-soluble polyester chips, appropriate amount of sodium hydroxide solution being 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 color paste, appropriate amount of water, 0.5-0.6 part of polyoxypropylene glycerol ether, 5-6 parts of natural leather powder, 2-3 parts of methacrylic acid, 0.8-1 part of casein liquor, 2-3 parts of glycerin, 0.8-1 part of tween 80, 0.5-0.7 part of an anti-aging agent RD and 0.7-0.9 part of sorbitan monooleate. By application of the natural leather powder to processing of the automotive interior decoration leather, moisture permeability, moisture absorbability, breathability and surface handfeel can be greatly improved, and the automotive interior decoration leather is higher in tear resistance as compared with natural leather and is environment friendly.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a high moisture-permeable automotive interior leather added with natural leather powder 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 automo...

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.
