Abstract
The invention belongs to the technical field of polyurethane synthetic leather and in particular relates to spandex ultra-soft protein leather for an earphone case and a preparation method thereof. The ultra-soft protein leather comprises wet-process bass and a dry-process veneer stuck on the wet-process bass, wherein the wet-process bass is prepared by coating a base fabric with wet-process paste; the wet-process paste is prepared from the following raw materials: N,N-dimethylformamide, color paste, a foam adjusting auxiliary agent, filler, a waterproof auxiliary agent and wet-process ultra-soft polyurethane resin. The dry-process veneer is prepared by coating release paper with a dry-process paste surface material and a dry-process paste bottom material, wherein the dry-process paste comprises the surface material and the bottom material; the surface material is prepared from a solvent, a color sheet and dry-process veneer polyurethane resin; the bottom material is prepared from thesolvent, the color sheet and the dry-process veneer polyurethane resin. The wet-process bass prepared by the invention has relatively large and uniform pore density, a stronger sponge feeling and goodair permeability; a spandex bottom fabric is compounded so that a prepared product has good wear-resisting and mildewing-resisting performance; when the product is processed into the earphone case, the touch feeling is comfortable.
Description
technical field [0001] The invention belongs to the technical field of polyurethane synthetic leather, and in particular relates to a four-sided elastic supersoft protein leather for earphone sleeves and a preparation method thereof. Background technique [0002] Polyurethane is a new type of synthetic material. Due to its special molecular structure, it has both the high elasticity of rubber and the high strength of plastics. Therefore, it has developed rapidly in recent decades in terms of both the scope of application and the number of applications. Ultra-soft polyurethane resin refers to 100% modulus less than 30kgf / cm 2 of polyurethane resin. Ultra-soft polyurethane has excellent elasticity and good hand feel, but generally its weather resistance, mildew resistance, corrosion resistance and air permeability are difficult to meet the requirements of practical applications. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a four-si...
