Problems solved by technology

[0003] The mobile power jacket is used as the protection mechanism of the mobile power supply. The existing jacket structure is mostly made of silicone rubber. The existing silicone rubber jacket has poor antistatic effect, easy to absorb dust, tensile strength, tear strength and wear resistance. The performance is poor, and the physical and mechanical properties change greatly after long-term use, so it is not suitable for promotion and use

Abstract

The invention discloses a formula of antistatic silicon rubber. The antistatic silicon rubber is prepared from the following raw materials in parts by weight: 40-50 parts of silicon rubber, 5-7 partsof vinylsiloxane rubber, 3-5 parts of stearic acid, 5-10 parts of fluorosilicone rubber, 1-3 parts of vulcanizer, 7-10 parts of reinforcing filler, 3-5 parts of weak reinforcing filler, 3-5 prats of additive, and 3-5 parts of coloring agent. The reinforcing filler is prepared from acetylene carbon black, conductive furnace black and conductive channel black materials, so that the antistatic silicon rubber has good conductive performance and good antistatic performance; the weak reinforcing filler is prepared from a mixture of diatomite, titanium dioxide and quartz powder, which is used as an antistatic filler; the raw materials are all from minerals, are low-cost and can be widely used, the production cost is low; the vinylsiloxane rubber is used as the main raw material, thereby improvingthe tensile strength and tear strength of the prepared silicon rubber; and the additive is a mixed solution of polyvinyl alcohol coating liquid and hardening liquid, thereby improving the wear resistance of the product remarkably, and prolonging the service life of the product, therefore, the antistatic silicon rubber can be widely promoted.

Description

technical field [0001] The invention relates to the technical field of production of mobile power supply jackets, in particular to a formula for antistatic silicone rubber, and also relates to a preparation method for antistatic silicone rubber. Background technique [0002] Mobile power is also called power bank, travel charger, etc. It is a portable charger that integrates power supply and charging functions, and can charge digital devices such as mobile phones and tablet computers anytime, anywhere. Generally, lithium batteries (or dry batteries, less common) are used as power storage units, which are convenient and quick to use. [0003] The mobile power jacket is used as the protection mechanism of the mobile power supply. The existing jacket structure is mostly made of silicone rubber. The existing silicone rubber jacket has poor antistatic effect, easy to absorb dust, tensile strength, tear strength and wear resistance. The performance is poor, and the physical and m...
