Abstract

The invention discloses wear-resistant antifouling high-physical-property polyurethane synthetic leather for consumer electronics and a preparation method of the wear-resistant antifouling high-physical-property polyurethane synthetic leather. The wear-resistant antifouling high-physical-property polyurethane synthetic leather for consumer electronics sequentially comprises an antifouling layer, asurface layer, a middle layer, a bonding layer and a base cloth layer from outside to inside, wherein the antifouling layer is made of water-based polyacrylic acid slurry, the surface layer is made of polycarbon type polyurethane slurry, the middle layer is made of polyether type polyurethane slurry, the bonding layer is made of double-component polyether type polyurethane slurry, and the base cloth is polyester knitted fabric. According to the wear-resistant antifouling high-physical-property polyurethane synthetic leather for consumer electronics, high-wear-resistant and high-hydrolysis-resistance polyurethane resin is adopted to be attached to the cloth base, then treatment is carried out through a water-based polycarbon type polyurethane antifouling treatment agent, the prepared high-physical-property synthetic leather for consumer electronics is full in hand feeling, fine and smooth in touch feeling and high in durability, and a new choice is provided for materials for consumer electronics.

Description

technical field [0001] The invention belongs to the field of polyurethane synthetic leather manufacturing, in particular to a polyurethane synthetic leather for consumer electronics with wear-resistant, antifouling and high physical properties and a preparation method thereof. Background technique [0002] At present, the use of consumer electronic products is increasing, and some of the packaging materials used in them are also increasing. For example, there are many choices of materials used for the back shell of the mobile phone and the keyboard of the tablet computer, such as plastic material, metal material, glass material, etc. Each material has certain disadvantages, such as low-grade plastic material and easy deformation of metal material , the glass material is fragile. In recent years, mobile phone back shells made of genuine leather have gradually become popular. This material feels full and delicate, has a high-grade sense, will not break, and is not easy to def...
