Abstract

The invention discloses a wear-resistant and waterpoof silicon rubber-TPU (Thermoplastic Polyurethane) composite fabric applied on shoes. The wear-resistant and waterpoof silicon rubber-TPU compositefabric comprises a silicon rubber layer, wherein a surface layer is coated on one surface of the silicon rubber layer, and a TPU thin film and a bottom-layer fabric for the shoes are stacked on the other surface of the silicon rubber layer; the silicon rubber layer comprises the following materials in parts by weight: 100 parts of base rubber of vinyl silicon rubber, 10-20 parts of vinyl silicon oil, 3-5 parts of high-viscosity raw rubber, 5-10 parts of high vinyl silicon oil, 5-10 parts of hydrogen-containing silicon oil and 1-3 parts of silane coupling agent. The invention also discloses a manufacturing technology of the wear-resistant and waterpoof silicon rubber-TPU composite fabric applied on shoes. The wear-resistant and waterpoof silicon rubber-TPU composite fabric and the manufacturing technology disclosed by the invention have the beneficial effects that the process is simple, and the implementation is easy; a layer of silicon rubber is coated on the TPU surface, so that the defects of the existing TPU composite fabric are overcome, and the TPU composite fabric can be applied on shoe products without the phenomena of difficult cleaning, yellowing, mildewing and decaying and the like.

Description

technical field [0001] The invention relates to the field of silicone rubber manufacturing, in particular to a wear-resistant and waterproof silicone rubber-TPU composite fabric applied to footwear and its manufacturing technology. Background technique [0002] Composite fabric is a composite fabric with high windproof, waterproof, aging resistance and thermal insulation functions. It has the comprehensive properties of various materials, so it has been widely used. Among them, TPU composite fabrics are widely used, mainly due to the wide range of hardness, wear resistance, oil resistance, transparency, and good elasticity of TPU materials. They are widely used in daily necessities, sporting goods, toys, decorative materials and other fields. However, TPU composite fabrics are rarely used in footwear products. The main reason is that TPU materials have disadvantages such as poor weather resistance, easy yellowing, poor hydrolysis resistance, and poor self-cleaning performanc...
