[0020] This utility model embodiment provides a flame-retardant synthetic leather for automotive interiors, such as... Figure 1-3 As shown, the flame-retardant synthetic leather for automotive interiors includes: a synthetic leather body for automotive interiors composed of an abrasion-resistant base layer 1, a first latex layer 2, an intermediate layer 3, a flame retardant 4, a second latex layer 5, a flame-retardant layer 6, and a tear-resistant layer 7. The first latex layer 2 is disposed on top of the abrasion-resistant base layer 1, the intermediate layer 3 is disposed on top of the first latex layer 2, the flame retardant 4 is disposed between the intermediate layer 3 and the first latex layer 2, the second latex layer 5 is disposed on top of the intermediate layer 3, the flame-retardant layer 6 is disposed on top of the second latex layer 5, and the tear-resistant layer 7 is disposed on top of the flame-retardant layer 6.
[0021] In this embodiment, the synthetic leather body for automotive interiors, composed of a wear-resistant base layer 1, a first latex layer 2, an intermediate layer 3, a flame retardant 4, a second latex layer 5, a flame retardant layer 6, and a tear-resistant layer 7, can be bonded together using environmentally friendly adhesive, sewing, or other methods. The wear-resistant base layer 1 is in direct contact with external objects, and its wear-resistant properties effectively resist friction and reduce wear on the synthetic leather body. The first latex layer 2 and the second latex layer 5 provide a certain cushioning effect, enhancing the overall elasticity and softness, making the synthetic leather body more comfortable to use. The flame retardant 4 is placed between the intermediate layer 3 and the first latex layer 2; when exposed to a fire source, the flame retardant 4 will... The flame retardant layer 6 has a certain flame retardant property and works synergistically with the flame retardant agent 4 to further enhance the flame retardant effect of the synthetic leather body. In the event of a fire, it can effectively slow down the burning speed and buy passengers more time to escape. With the use of the tear-resistant layer 7, when the synthetic leather body is subjected to external force, the tear-resistant layer 7 can resist the tearing force due to its high strength, preventing the synthetic leather body from tearing and extending the service life of the synthetic leather. The various layers work together to form a synthetic leather for automotive interiors with good flame retardant, wear resistance and tear resistance.
[0022] In a further preferred embodiment of the present invention, the tear-resistant layer 7 is woven from a first reinforcing thread 701, a second reinforcing thread 702 and a third reinforcing thread 703, wherein the first reinforcing thread 701 and the second reinforcing thread 702 are both made of nylon and the third reinforcing thread 703 is made of polyester fiber.
[0023] In this embodiment, the first reinforcing thread 701 and the second reinforcing thread 702 are interwoven sequentially, and the third reinforcing thread 703 is interwoven between the first reinforcing thread 701 and the second reinforcing thread 702. This weaving structure makes the tear-resistant layer 7 have a tighter and more stable structure. The interwoven first reinforcing thread 701 and the second reinforcing thread 702 provide a basic tear-resistant framework for the synthetic leather body, and the interweaving of the third reinforcing thread 703 further enhances the connection strength, so that the synthetic leather body can more effectively disperse stress when subjected to external force, reduce the risk of tearing, and extend the service life of the synthetic leather body. The nylon material has the characteristics of high strength and good wear resistance, so that the first reinforcing thread 701 and the second reinforcing thread 702 can effectively improve the tear resistance of the synthetic leather body. The polyester fiber material has good wrinkle resistance and shape retention. The addition of the third reinforcing thread 703 not only further enhances the structural stability of the synthetic leather body, but also makes the synthetic leather body better able to recover its original shape when subjected to external force.
[0024] In a further preferred embodiment of this utility model, the flame-retardant layer 6 is woven from flame-retardant fibers.
[0025] In this embodiment, the flame-retardant layer 6 is woven from flame-retardant fibers. Flame-retardant fibers have the characteristics of being difficult to burn when exposed to fire and extinguishing immediately upon removal of the fire source. The flame-retardant layer 6 woven from these fibers provides effective fire protection for the synthetic leather body.
[0026] In a further preferred embodiment of the present invention, ventilation holes are provided on the wear-resistant base layer 1, the first latex layer 2, the intermediate layer 3, the flame retardant 4, the second latex layer 5, the flame retardant layer 6, and the tear-resistant layer 7.
[0027] In this embodiment, the use of vents can improve the breathability of the leather body, making it more comfortable for people to use.
[0028] In a further preferred embodiment of this utility model, the intermediate layer 3 is a bio-based microfiber synthetic leather layer.
[0029] In this embodiment, the middle layer 3 is a bio-based microfiber synthetic leather layer. This unique material has many advantages, with an extremely fine fiber structure that makes the synthetic leather softer and greatly improves the comfort of riding.
[0030] In a further preferred embodiment of the present invention, the wear-resistant base layer 1 is a polyurethane layer, and the thickness of the wear-resistant base layer 1 is 0.8 mm.
[0031] In this embodiment, the 0.8mm thick polyurethane wear-resistant base layer 1, as the layer that is in direct contact with the outside world, plays an irreplaceable and important role. The polyurethane material itself has the characteristics of high strength and high elasticity, which enables the wear-resistant base layer 1 to effectively resist various frictions and scratches generated in daily use.
[0032] In summary, compared with related technologies, this solution, through the wear-resistant base layer 1, effectively resists friction and reduces wear on the synthetic leather body when in contact with external objects. The use of the first latex layer 2 and the second latex layer 5 provides a certain buffering effect, enhancing the elasticity and softness of the synthetic leather body, making it more comfortable to use. The addition of flame retardant 4 effectively reduces the spread and burning speed of flames when exposed to fire sources, thereby improving the flame retardant performance of the synthetic leather body. The use of flame retardant layer 6 further enhances the flame retardant effect of the synthetic leather body, effectively slowing down the burning speed in the event of a fire, providing passengers with more escape time. The use of tear-resistant layer 7 effectively resists tearing forces when the synthetic leather body is subjected to external pulling, preventing tearing and extending the service life of the synthetic leather body.
