Problems solved by technology

[0007] However, the above application text does not disclose the artificial leather material which has infrared reflection function and is used in summer after perforation and also has cool and breathable effect.
Especially in the hot summer, the surface temperature of the existing leather, artificial leather and other materials is obvious after a period of sunlight exposure.
In summer, when the vehicle is parked outdoors and exposed to the sun for a period of time, the temperature inside the car can reach almost 65°C, and the leather material on the seat can also reach the same temperature. To ensure driving comfort, it is often necessary to open the door and turn on the air conditioner to cool down for a period of time, which causes waste of energy and time

Abstract

The invention discloses an artificial leather with cold air permeability, and a preparation method and an application thereof, belonging to the technical field of automotive interior materials. The artificial leather comprises a base fabric layer, a PVC cementation layer, a PVC dense layer and a surface layer, which are orderly arranged from bottom to top, wherein the PVC dense layer comprises thefollowing raw materials in parts by mass: 100 parts of polyvinyl chloride, 50-70 parts of plasticizer, 4-14 parts of infrared reflection assistant, 1-7 parts of stabilizer and 2-8 parts of color paste. Such artificial leather material not only can provide enough drilling degree of freedom and guarantee relatively higher strength after drilling, but also has an infrared reflection function, is used in an automotive interior product, and cannot make a surface of the automotive interior product have quick temperature rise when being used in summer.

Description

technical field [0001] The invention relates to an artificial leather, which belongs to the technical field of automotive interior materials, in particular to an artificial leather with cool air permeability and a preparation method and application thereof. Background technique [0002] At present, with the development of the economy, the demand for automobiles has further expanded, and at the same time, most consumers have further improved requirements for automobile quality and cost performance. Therefore, the competition among major OEMs is becoming more and more fierce, and the pressure to reduce costs is increasing. It has become a trend to use high-performance PVC leather to replace genuine leather on the A side of the seat, and to use microfiber materials to reduce costs. As an important visual part of the car, the car seat covered with PVC artificial leather is widely concerned by consumers for its mechanical properties, environmental protection performance and durab...
