Problems solved by technology

In actual use, these two kinds of synthetic leather are not resistant to aging, have a short service life, and are not easy to recycle
[0004] The Chinese patent with the publication number CN1702234A discloses a breathable silicone synthetic leather and its production method. The silicone rubber described in the patent is a liquid silicone rubber. Since the liquid silicone rubber is a viscous liquid with certain fluidity, Therefore, it applies glue through the gluing process of the coating mechanism, which has the disadvantages of "easy to generate air bubbles, uneven coating, and glue penetration through the substrate".
The invention patent of CN101280521A discloses a liquid silicone rubber for artificial leather. The invention uses a solvent to dilute the liquid silicone rubber, and adopts a method of dip coating to make artificial leather. This method can easily make the base cloth see through, and it is not easy to scrape and emboss the pattern. Production The solvent used in the process is prone to danger, and the solvent volatilizes after baking, which is uneconomical and environmentally friendly

Abstract

The invention relates to environmental-friendly synthetic organosilicon leather and a method for producing the same. The synthetic organosilicon leather comprises vinyl polysiloxane gum, white carbon black, a structured treatment agent, a plastifying agent, an inhibitor, hydrogen containing silicone oil, a platinum catalyst and silicone rubber masterbatch. The method for producing the synthetic organosilicon leather comprises the following steps: mixing the raw materials to obtain solid mixed silicone rubber through vulcanization via addition, rolling the solid mixed silicone rubber by a multi-roll rolling machine to fit textile-based fabric, heating and vulcanizing to form the synthetic organosilicon leather. The environmental-friendly synthetic organosilicon leather is efficiently produced with a simple process and can be produced on a large scale. The produced synthetic organosilicon leather has good mechanical properties and excellent characteristics of being resistant to high andlow temperature, weathering aging and physical inertia, is easy to cut and sew and is waterproof and breathable. The combustion and decomposition product of the synthetic organosilicon leather contains no harmful substance, can be recycled and accords with environmental protection requirements.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, and in particular relates to an environment-friendly organic silicon synthetic leather and a preparation method thereof. Background technique [0002] Silicone materials have excellent high and low temperature resistance, weather resistance, water resistance, electrical insulation and physiological inertia, etc., and are widely used in aerospace, electrical and electronic, construction, automotive machinery and other industries, as well as medical and health, and various fields of daily life. Silicone rubber is one of the silicone materials. [0003] At present, most artificial synthetic leathers on the market are mainly polyvinyl chloride (PVC) and polyurethane (PU) synthetic leathers, which are used to manufacture consumer goods and decorative materials such as shoes, clothing, boxes, bags, and chairs. Vinyl chloride, the raw material for producing polyvinyl chloride, and isocyanate,...
