Antistatic imitation leather material for automobile interior decoration and production method thereof

Abstract

The invention discloses an antistatic imitation leather material for automobile interior decoration, made from the following materials according to parts by weight: 67-77 parts of polyamide, 25-26 parts of alkali-soluble polyester chips, suitable sodium hydroxide solution 20% in concentration, 50-53 parts of waterborne polyurethane, suitable water, 0.6-0.8 part of sodium alpha-olefin sulfonate, 4-5 parts of polyethylene glycol 400, 4-5 parts of nano ATO powder, 0.8-1 part of glycerol monostearate, 2-3 parts of oxalic acid, 0.8-1 part of propylene glycol monoethyl ether, and 3-4 parts of methyl methacrylate. By adding the glycerol monostearate modified nano ATO powder, the problem that powder aggregates easily can be solved, and the powder can be dispersed evenly; in cooperation with polyethylene glycol 400 and oxalic acid, antistatic property of a finished product is further enhanced, and the toughness and strength of the finished product are improved.

Description

technical field [0001] The invention relates to the technical field of synthetic leather materials, in particular to an antistatic leather-like 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 automotive interior lea...

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 Therefore, ordinary PVC artificial leather in automotive interiors has gradually been replaced by polyurethane (PU) synthetic leather.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