Description
Technical field
The present invention relates to rubber composite manufacture field, particularly special paracril gasket of a kind of electrical condenser and preparation method thereof.
Background technology
Electrical condenser is conventionally referred to as electric capacity, is one of a large amount of electronic components that use in electronics, be widely used in circuit every aspects such as straight-through friendship, coupling, bypass, filtering, resonant tank, energy transformation, controls.Electrical condenser is made up of housing, capacitor core, end cap and connection terminal, steeping medium is housed in capacitor casing, steeping medium is generally vegetables oil or mineral oil, the sealing position of electrical condenser is equipped with gasket or sealing-ring, because the Working environment of electrical condenser varies, some electrical condensers need to be worked under rugged environment, and electrical condenser gasket needs high temperature resistant, cold-resistant, acid and alkali-resistance, salt spray resistance etc. to have different requirements.
Summary of the invention
The object of this invention is to provide special paracril gasket of a kind of electrical condenser and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
The special paracril gasket of a kind of electrical condenser, is made up of the raw material of following weight part: paracril 55-60, zinc oxide 3-4, sulphur 1-2, stearic acid 2-3, antioxidant MB 1-2, Trisodium Citrate 1-3, methyl acrylate 4-5, methyl phenyl silicone oil 2-3, the two amine hydroxybenzene 0.5-1 of ethylene, trees ashes 10-13, barium sulfate 3-5, carbon black 10-12, attapulgite modified 12-15;
The described attapulgite modified raw material by following weight part is made: attapulgite 30-34, diphenylmethanediisocyanate 3-4, tri (propylene glycol) diacrylate 3-4, tripoly phosphate sodium STPP 5-6, jade 4-5, silane resin acceptor kh-550 1-2, silicon carbide 4-5,2,6 ditertiary butyl p cresol 1-2, morpholine 1-2, thiol-butyl tin 1-2, Radix Angelicae Sinensis oil 1-2; Preparation method puts attapulgite, jade to be mixed in calcining furnace to calcine 3-4 hour at 700-720 DEG C, cooling, put into 10-12% hydrochloric acid soln and soak 1-2 hour, filter and take out, clean and dry with clear water, be ground into 200-300 order powder, mix with other remaining component, grinding distribution 1-2 hour, to obtain final product.
The special paracril gasket of electrical condenser of the present invention, is made up of following concrete steps: paracril, zinc oxide, methyl acrylate, methyl phenyl silicone oil are added in Banbury mixer, be heated to 80-85 DEG C, mixing 3-5min; Then be warming up to 110-130 DEG C, then add sulphur, stearic acid, antioxidant MB, Trisodium Citrate, mixing 6-8min, then add the two amine hydroxybenzenes of ethylene, barium sulfate, carbon black to continue mixing 4-6min; Add the mixing 5-6min of all the other remaining components, obtain rubber mass of the present invention.
Excellent effect of the present invention is: the present invention adds attapulgite modified, has improved the processing performance of sizing material, uses environment-friendly type Synergist S-421 95, reduces its toxic side effect and the pollution to environment; The present invention fills a prescription rationally, and technique is simple, with short production cycle, and efficiency is high, and the gasket of its production has good oil-proofness, and long service life, and cost is low.
