Description
Technical field
The invention belongs to chemical field, relate to a kind of making method of high-temperature resistant rubber.
Background technology
Rubber is a kind of resilient polymkeric substance.Rubber can be obtained from the myron of some plants, can be also artificial, both considerable application and products, and such as tire, packing ring etc., becomes Important Economic crop then.The plantation of rubber mainly concentrates on south east asia ，Ru Thailand, Malaysia, Indonesia.
Rubber is divided into natural rubber and synthetic rubber by raw material.By form, be divided into block rubber, latex, fluid rubber and powdered rubber.Latex is the colloidal water dispersion of rubber; Fluid rubber is the oligopolymer of rubber, before sulfuration, is not generally the liquid of thickness; Powdered rubber be latex is processed into Powdered, in order to batching and processing and fabricating.The thermoplastic elastomer of the exploitation sixties in 20th century, without chemicure, and adopts the working method of thermoplastics to be shaped.Rubber is divided into again universal and extraordinary type two classes by using.Be isolator, be not easy conduction, if but get wet or different temperature, conductor likely become.Conduction is the easy situation of conduction about the electronics of material interior molecules or ion.
Room temperature vulcanized silicone rubber, owing to having good heat-resisting, cold tolerance and good electrical insulation capability, particularly at room temperature need not heat, pressurize and can solidify on the spot, and it is extremely convenient to use.Single-component ketoxime removing type silicon rubber in silicon rubber is because use temperature scope is wide, have that as large in volume resistance, the resistance to disruptive strength of excellent electrical insulation properties is high and corona-resistance property good, with good adhesive property, there is the performances such as good water-fast, corrosion-resistant, radiation hardness, resistance to atmospheric aging simultaneously, location, bonding, sealing and the cementation of fissures etc. that are widely used in components and parts in electronic product, electric installation, play insulation, dustproof, moistureproof, protection against corrosion and the effect such as shockproof.And silicon rubber is a kind of poor conductor of heat, under high temperature, silicon rubber is inner can put aside heat, causes its internal temperature higher, has virtually increased the actual temperature of bearing of silicon rubber, cause silicon rubber internal temperature to surpass envrionment temperature, thereby accelerate the aging speed of rubber inside.Existing basic employing be that filler metal oxide compound improves the thermal conductivity of polymer materials as silicon nitride, boron nitride as magnesium oxide, aluminum oxide and metal nitride in base polymer matrix, but have that loading level is large, glue storage is unstable, solidify after the easy shortcoming of aging yellowing.
Summary of the invention
Technical problem to be solved by this invention is to provide that raw material is cheap, the simple high-temperature resistant rubber preparation method of preparation method.
For solving above technical problem, the making method of a kind of high-temperature resistant rubber of the present invention, it comprises the steps:

(2) mixing raw material: the pottery by step (1) Suo Shu, be placed in stirrer, stir into ceramic powder, described terpolymer EP rubber, carbon black, ceramic powder, caking agent, vulcanizing agent, anti-aging agent are mixed;
(3) mixing: step (2) gained mixture to be carried out mixing, obtain mixing of rubber;
(4) extrusion molding: the mixing of rubber of step (3) gained is placed on to extrusion molding in pressure die-casting machine, becomes work in-process, described pressure is 600MPa-700MPa;
(5) sulfidizing: the work in-process normal temperature of step (4) gained is placed down in vulcanizing press and carries out sulfidizing, obtain high-temperature resistant rubber.
The anti-aging agent of above-mentioned steps (1) is NBC anti-aging agent.
