The invention discloses a silicone rubber and terpolymer EP rubber blend and preparation method thereof. The blend comprises the following components by weight: 70-80 parts of silicone rubber, 25-35 parts of terpolymer EP rubber, 3-5 parts of gas phase white carbon black, 10-12 parts of white carbon black, 2-4 parts of talc powder, 6-10 parts of organic montmorillonite, 0.5-2 parts of silane coupling agents, 4-7 parts of foaming agents, 0.2-0.3 parts of dimethicone, 1-5 parts of sulphur, 10-15 parts of rice husk ash, and 1-3 parts of anti-oxidant. According to the invention, white carbon black is replaced by gas phase white carbon black, and rice husk ash which is a by-product wasted in cereal processing is used as a cheap filling material, and the wasted rice husk ash can reduce production cost and minimize environment pollution.
Description
Technical field
The invention belongs to rubber technology field, specifically a kind of silicon rubber and terpolymer EP rubber blend and preparation method thereof.
Background technology
Silicon rubber alternately forms its main chain by siloxane bond (Si-O), and organic group (as methyl, ethyl, vinyl, phenyl, trifluoro propyl etc.) forms a kind of line style organopolysiloxane of its side group.Owing to introducing a small amount of vinyl in silicon rubber macromolecular structure, can greatly improve sulfuration and the processing characteristics of silicon rubber, so in the silicon rubber of application at present, mostly contain vinyl.Singularity due to structure, silicon rubber have many other materials the excellent properties that can not simultaneously possess, as the high temperature resistant and lower temperature resistance of brilliance, excellent oil resistant, resistance to solvent, resistance to ultraviolet, radiation resistance, good ageing resistance, good electrical insulating property and chemical stability and physiology inertia.Silicon rubber foam material is the porous macromolecular material of silicon rubber preparation after foaming, is called again sponge silicon rubber, microporous silicon rubber.According to foam structure, can be divided into closed pore, perforate and mix aperture foam silicone rubber.
Rice hull ash (RHA) is in processing rice process, the residuum after combusting rice hull, and the outer higher black rice hull ash (BRHA) of charring layer content that generates, its major ingredient is SiO2.
But because silicon rubber is expensive, cause its production cost to increase.Itself and terpolymer EP rubber are mixed with to the blend composition obtaining jointly and in prior art, possess some special knowledge yet, application is not also very extensive at present.
