Flame-retardant impact-resistant ultrafine fiber polyurethane synthetic leather for automobile interior trim and preparation method of synthetic leather

Abstract

The invention discloses flame-retardant impact-resistant ultrafine fiber polyurethane synthetic leather for automobile interior trim. The flame-retardant impact-resistant ultrafine fiber polyurethane synthetic leather is characterized by being 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 paste, an appropriate amount of water, 0.7-0.8 part of cocoanut fatty acid diethanolamide, 5-6 parts of expanded graphite, 2-3 parts of trichloroethyl phosphate, 1-1.2 parts of castor oil, 2-3 parts of phenolic resin emulsion, 0.8-1 part of cardanol and 2-3 parts of plastic clay. The prepared synthetic leather has the advantages that the touch sense is soft and comfortable, the impact resistance is achieved, postprocessing is easy, environment-friendly raw materials are adopted in the whole technological process, no harm is generated to the environment and human bodies, and the requirements of customers for the leather for automobile interior parts are met.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to a flame-retardant and impact-resistant microfiber polyurethane synthetic leather 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....

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.
