Glazed microfiber silicone rubber synthetic leather and manufacturing technology thereof

Abstract

The invention discloses a glazed microfiber silicone rubber synthetic leather, which is prepared by laminating a super bright glazed layer, a liquid silicone rubber layer, and a microfiber fabric in sequence. The liquid silicone rubber layer is composed of following raw materials in parts by weight: 50 to 80 parts of basic rubber of silicone rubber, 3 to 5 parts of silane coupling agent, 5 to 10 parts of hydrogen containing silicone oil, 0.1 to 0.5 part of platinum catalyst, 5 to 20 parts of color paste pigment, and 0.02 to 0.1 part of inhibitor. The invention also discloses a manufacturing technology of the glazed microfiber silicone rubber synthetic leather. Liquid silicone rubber with high hardness and elongation rate is taken as the basic material to prepare the silicone rubber synthetic leather; in order to guarantee the mechanical performance of the silicone rubber synthetic leather, hydrogen containing silicone oil with a high hydrogen content is taken as the crosslinking agent,and the obtained glazed microfiber silicone rubber synthetic leather has an excellent bending resistant performance. A layer of colored silicone rubber is painted on the microfiber surface so as to fully fill the gaps in the microfiber surface, then the microfiber and transparent silica gel are adhered together, and the mirror effect is very obvious.

Description

technical field [0001] The invention relates to silicone rubber synthetic leather, in particular to a mirror-surface superfiber silicone rubber synthetic leather and a manufacturing technology of the mirror-surface superfiber silicone rubber synthetic leather. Background technique [0002] Microfiber synthetic leather is a kind of high-grade artificial leather composed of fiber base material, adhesive material and surface layer resin, which is similar to genuine leather. The development of microfiber industry has a history of 30 to 40 years. Whether it is technology or industrial scale, Japan has been leading the way. [0003] After entering the new century, my country's synthetic leather technology has been continuously invested in research and development, and has continued to innovate. There has been a great leap in technology and created a technological breakthrough. The common leathers on the market are observed under a microscope, with obvious concave and convex waves...

AI Technical Summary

Problems solved by technology

The common leather on the market is observed under a microscope. The unevenness is very obvious, the flatness is poor, the smoothness is relatively low, and the reflective performance is poor. The products made of traditional synthetic leather look dull and old.

[0004] Although PU mirror synthetic leather can solve the above problems, there are still deficiencies, mainly in that PU synthetic leather products will leave obvious creases or wrinkles on the surface after bending or deformation, and when the external force is removed Can not be completely restored to the original state, thus affecting the appearance of the product
