Description

Technical Field

[0001] The utility model relates to the technical field of synthetic leather, in particular to a high-toughness, wear-resistant and non-slip synthetic leather. Background Art

[0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute material. Among them, polyurethane synthetic leather has the advantages of high strength, wear resistance, cold resistance, breathability, aging resistance, solvent resistance, soft texture, beautiful appearance, etc. It also has good processing performance. It is an ideal imitation leather product to replace natural leather, and its performance is better than PVC leather. Polyurethane synthetic leather is widely used in clothing, footwear, luggage, furniture and other industries.

[0003] Polyurethane synthetic leather is usually made of impregnated non-woven fabric as the base fabric layer and microporous polyurethane as the grain layer. A foaming layer is set between the base fabric layer and the polyurethane layer in the polyurethane synthetic leather to further improve the softness of the synthetic leather. The foaming layer and the polyurethane layer are only bonded by an adhesive, so the connection strength between the foaming layer and the surface of the polyurethane layer is limited, which makes it easy for the edges of the synthetic leather to delaminate when in use. Utility Model Content

[0004] The utility model aims to provide a high-toughness wear-resistant and non-slip synthetic leather, which can improve the non-slip effect of the synthetic leather surface, and utilize protrusions to improve the adhesion in the synthetic leather, avoid delamination at the edge of the synthetic leather, thereby increasing the service life of the synthetic leather.

[0005] To achieve the above object, a high-toughness wear-resistant and anti-skid synthetic leather is provided, comprising: a base fabric layer, a foaming layer and a polyurethane layer, wherein the foaming layer is arranged on the base fabric layer and the polyurethane layer, the surface of the polyurethane layer is provided with an anti-skid groove, the surface of the polyurethane layer is provided with a wear-resistant coating, the bottom of the polyurethane layer is provided with a convex block, and the convex block extends into the foaming layer, an adhesive is arranged between the base fabric layer, the foaming layer and the polyurethane layer, and the base fabric layer, the foaming layer and the polyurethane layer are fixedly connected by the adhesive. The anti-skid effect of the surface of the synthetic leather can be improved, and the convex block is used to improve the adhesion of the synthetic leather, so as to avoid delamination at the edge of the synthetic leather, thereby improving the service life of the synthetic leather.

[0006] According to the high-toughness wear-resistant and non-slip synthetic leather, the wear-resistant coating is an organic silicon wear-resistant coating, which further improves the wear resistance of the surface of the synthetic leather and prolongs the service life of the synthetic leather.

[0007] According to the high-toughness wear-resistant and non-slip synthetic leather, the surface of the convex block is provided with tiny holes to increase the contact surface with the adhesive and improve the connection strength between the foaming agent and the polyurethane layer.

[0008] The above scheme has the beneficial effects of improving the anti-skid effect of the surface of the synthetic leather by the anti-skid groove, and using the protrusions to extend into the foaming layer to fix the polyurethane layer, while increasing the contact surface between the polyurethane layer and the adhesive, and improving the connection strength between the foaming layer and the polyurethane layer, avoiding delamination at the edge of the synthetic leather, thereby increasing the service life of the synthetic leather.
