Abstract
The invention discloses a rubber gasket containing nano mica powder. The rubber gasket is prepared from the following raw materials in parts by weight: 80-120 parts of methyl vinyl silicone rubber, 20-30 parts of ethylene-propylene-diene monomer, 2.2-2.5 parts of hexafluorobisphenol A, 1.5-1.8 parts of benzyltriphenylphosphonium chloride, 7-9 parts of toluene diisocyanate, 6-8 parts of dicumyl peroxide, 8-10 parts of nano mica powder, 5-8 parts of nano bentonite, 8-12 parts of polyamide wax micropowder, 12-15 parts of fast extruding furnace black N660, 3-5 parts of paraffin oil, 2.2-2.4 parts of sulfur, 6-8 parts of zinc oxide, 3-4 parts of stearic acid, 1.5-2.5 parts of siloxane and 5-7 parts of modified tree ash. The rubber gasket has excellent overall performances such as wear resistance, high-temperature resistance, acid-base resistance, corrosion resistance, radiation resistance and the like, simultaneously has self-lubricating performance and impermeability, excellent insulating performance, good impact elasticity and long service life and is widely applied to various electronic and electrical devices.
Description
Technical field
The present invention relates to gasket materials field, relate in particular to a kind of rubber sheet gasket that contains nano mica powder.
Background technology
Pad is two mechanical seals between object, because machining surface can not be perfect, uses packing ring can fill up irregularity.Pad is normally made by flaky material, as rubber, metal, cork, felt, glass fibre or plastic polymer etc.Along with scientific and technological development, pad is more and more extensive, meanwhile, also more and more higher to the performance requriements of pad for the application on electron device, such as shockproof, waterproof, ventilative, corrosion-resistant, weather-resistant, resistance to elevated temperatures.But use at present the over-all propertieies such as work-ing life of pad prepared by single-material and durability, high thermal resistance, weatherability to be difficult to reach requirement, some pads need often to change and detect, and to production, have brought inconvenience.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rubber sheet gasket that contains nano mica powder is provided, material prescription is reasonable, there is the over-all propertieies such as excellent wear resistance, high temperature resistant, acid and alkali-resistance, corrosion-resistant, radiation hardness, insulating property are good, and shock elasticity is good, long service life.
The present invention adopts following technical scheme to achieve these goals:
A kind of rubber sheet gasket that contains nano mica powder, it is to be made by the raw material of following weight parts: methyl vinyl silicone rubber 80-120 part, terpolymer EP rubber 20-30 part, hexafluoro bisphenol-a 2.2-2.5 part, BPP 1.5-1.8 part, toluene di-iso-cyanide ester 7-9 part, oxidation diisopropylbenzene(DIPB) 6-8 part, nano mica powder 8-10 part, nano-bentonite 5-8 part, polyamide wax micropowder 8-12 part, fast extrusion carbon black N66012-15 part, paraffin oil 3-5 part, sulphur 2.2-2.4 part, zinc oxide 6-8 part, stearic acid 3-4 part, siloxanes 1.5-2.5 part, modification trees ashes 5-7 part.
Described modification trees ashes are prepared by following methods: the hydrochloric acid soln that is first 8-10% by trees ashes by concentration soaked after 5 hours, with deionized water wash, to neutral, dry; Then in the trees ashes of drying, add be equivalent to its weight 5-6% nano-sized carbon, 2-3% 2,4, the aluminium hydroxide of the tributyl citrate of 6-trisphenol, 1-2%, the ferrocene of 1-2%, 3-5%, under 5300-5500 rev/min, stir after 40 minutes, after ovendry power is broken into and crosses 100 mesh sieves after powder and get final product.
The described rubber sheet gasket that contains nano mica powder, preparation method is: Fluoride for Raw Material rubber and polyvinyl chloride, curing Dibenzo thiazole, bismaleimides, two Lauryl Alcohol ester are mixed, add melting 1-2 hour in smelting furnace, temperature is controlled at 180-220 ℃, add again surplus stock mix and blend, mixing 2-3 hour at 120-150 ℃, last compression moulding, is cut into finished product.
Compared with the prior art, beneficial effect of the present invention is as follows:
Rubber sheet gasket of the present invention is by adding nano mica powder and modification trees ashes, elasticity and toughness, heat resistance, acid-proof alkaline and the corrosion resistance nature of material have effectively been increased, material prescription of the present invention is reasonable, there is the over-all propertieies such as excellent wear resistance, high temperature resistant, acid and alkali-resistance, corrosion-resistant, radiation hardness, have self lubricity and gas tightness, insulating property are good simultaneously, and shock elasticity is good, long service life, can be widely used in various electronic electric equipments.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
