Problems solved by technology

[0005] For automotive interior leather made of TPU, the temperature inside the car is a factor that has a huge impact on the performance of TPU synthetic leather. Under the conditions of summer exposure, the temperature inside the car can easily exceed 70 degrees Celsius, and the temperature inside the car will drop at night, and When the driver drives the car and turns on the air conditioner, the temperature inside the car also changes greatly, which seriously affects the service life of the TPU interior leather

Abstract

The invention discloses weather-resistant automotive interior leather. The automotive interior leather comprises a foaming base layer, a bonding layer, a thermoplastic polyurethane elastomer layer anda water-based polyurethane decorative layer from the bottom to the top; and the foaming base layer, the bonding layer and the thermoplastic polyurethane elastomer layer are bonded through hot pressing, the water-based polyurethane layer coats the thermoplastic polyurethane elastomer layer, the bonding layer is a TPU hot melt adhesive film, and especially a thermoplastic polyurethane elastomer isstructurally modified through aramid chopped fibers. According to the automotive interior leather provided by the invention, the purpose of performing modification through structural design and formulation to enhance the weather resistance of the automotive interior leather is realized.

Description

technical field [0001] The invention relates to the field of automotive interior leather, in particular to a weather-resistant automotive interior leather. Background technique [0002] Polyurethane Synthetic Leather belongs to the category of polyurethane elastomers. It has soft luster, natural, soft touch, and strong leather-like appearance. It has excellent adhesion to the substrate, wear resistance, flex resistance, and aging resistance. Excellent mechanical properties, but also has the advantages of good cold resistance, breathable, washable, convenient processing, low price, etc., is the most ideal substitute for natural leather. [0003] TPU is widely used in many fields such as synthetic leather, automobile manufacturing, shoe materials, films, fabrics, medicine, and military affairs. It has physical properties unmatched by other plastic materials. Good toughness, abrasion resistance, cold resistance, oil resistance, water resistance and aging resistance. High wat...
