Problems solved by technology

Otherwise, it will cause a great waste of social resources and pollute the environment at the same time.
At present, the method of recycling vulcanized silicone rubber is to adopt high temperature cracking to produce raw materials D 4 That is, octamethylcyclotetrasiloxane, but this process has the disadvantages of high cost and complicated process

Embodiment Construction

[0028] Such as image 3 Shown, it is the reclaiming of silicone rubber of the present invention and its application process flow chart, it is characterized in that: it is to process and reuse waste silicone rubber as filler, and this process flow comprises three operations:

[0029] 1) Crushing of rubber

[0030] Such as figure 1 As shown, it is a flow chart of the crushing process of the sizing material of the present invention. After the silicone rubber is formed, it has different physical shapes, such as color, hardness, etc. Therefore, before recycling, the rubber materials to be recycled must be classified according to color or hardness, and then added with antistatic agent and crushed with a pulverizer. The glass transition temperature Tg is -189°C. When crushed mechanically, it will stick together, so an antistatic agent should be added when crushing. Wherein the antistatic agent component is 0.1%-0.15% quaternary ammonium salt aqueous solution, and in the crushing p...

Abstract

The present invention is recovery process and application of silicone rubber and the recovered silicone rubber is reused as stuffing. The recovery process includes three steps: the crushing of waste silicone rubber, the pugging of waste silicone rubber, and throwing the recovered silicone rubber in the forming of silicone rubber product. The surface of the product with recovered silicone rubber particles has different elasticity, hardness and elongation, and thus special anti-sliding, anti-stick and other effects. The recovery process may be used in manufacturing bathing cap, carpet, foot padin automobile, swimming fins, etc.

Description

technical field [0001] The invention relates to a recovery process of silicon rubber and its application. Background technique [0002] Because of its excellent high temperature resistance, low temperature resistance, corrosion resistance, electrical insulation, non-toxic, flame retardant, and stable chemical properties (can be used for a long time at -50°C-250°C), silicone rubber is used in all walks of life in society ZOZEN is being used more and more widely. However, the finished product of silicone rubber must be vulcanized under high temperature and high pressure in the production process to form a product. The vulcanization of silicone rubber is an irreversible chemical reaction. Therefore, the recycling and reuse of scraps of vulcanized silicone rubber products (including accessories in production) and discarded silicone rubber products has become the current focus of the silicone rubber industry. a problem. Otherwise, it will cause a great waste of social resource...
