Description
Technical field
The invention belongs to cable connector insulated enclosure field, more particularly to a kind of electric power sealing waterproof insulation rubber cement and its
Preparation method.
Background technology
With the increase of urban planning and construction, urban power distribution network transformation, aerial insulated wire is widely used, buried cable
Laying high-volume increases.Dug in electric power enterprise construction or cable in the accident maintenance such as disconnected, underground electric line joint often occur,
Present power circuit typically all carries insulated hull, occurs after power circuit joint, junction is exposed outside, or is twined using adhesive plaster
Around, oxidation is easily produced, occurs leaky, line security is influenceed, or cause contact resistance excessive, cause power circuit to use
The lost of life.
The content of the invention
, should the technical problem to be solved in the present invention is to provide a kind of electric power sealing waterproof insulation rubber cement and preparation method thereof
Rubber cement can be sealed effectively and insulation processing power circuit contact, the effect with air-isolation, isolation moisture and insulation, protection
The exposed line contacts in air or underground, to avoid line contacts oxidation electric leakage, contact resistance excessive, it is ensured that power circuit makes
Use the life-span.
The present invention technical solution be：
A kind of electric power seals waterproof insulation rubber cement, in parts by weight, is made up of following raw material：
100 parts of natural rubber；
30 parts of liquid polyisobutene；
10 parts of α pinene resin；
6 parts~6.5 parts of zinc oxide；
3 parts~3.5 parts of sulphur；
3.5 parts~4 parts of stearic acid；
0.4 part~0.6 part of altax；
1.3 parts~1.5 parts of Vulcanization accelerator TMTD；
58 parts~60 parts of channel black；
0.8 part~1 part of rubber antiager RD；
10 parts~10.5 parts of rosin.
A kind of electric power seals waterproof insulation rubber cement, and it is comprised the following steps that：
In parts by weight, by 100 parts of natural rubber particles and 58 parts~60 parts channel black uniform stirrings, then successively
Add 6 parts~6.5 parts zinc oxide, 3 parts~3.5 parts sulphur, 3.5 parts~4 parts stearic acid, 0.4 part~0.6 part altax and
1.3 parts~1.5 parts Vulcanization accelerator TMTDs stir, and finally sequentially add 30 parts of liquid polyisobutene, 0.8 part~1 part rubber and prevent
Old agent RD, 10 parts~10.5 parts rosin and 10 parts of α pinene resins stir, be then heated to 100 DEG C keep 40min~
60min, is cooled to room temperature, packs.
Zinc oxide, the vulcanizing activator and reinforcing agent of rubber cement synthesis, can promote vulcanization, improve rubber cement crosslinking close
Degree, can preferably improve tack of materials, improve the adhesive force and ageing-resistant performance of rubber cement.
Sulphur, in rubber cement building-up process, forms disulfide bond between the rubber molecule of chain, makes rubber molecule structure
More stablize.
Stearic acid, rubber cement synthesis vulcanizing activator, plasticizer and softening agent, stearic acid and zinc oxide compound use have
Synergy, plays excellent vulcanization promotion and activation.
Rubber accelerator DM, chemical name：2nd, 2'- dithio-bis-benzothiazoles, rubber cement synthesis accelerant, in sizing material
Easily disperse, do not pollute, in the presence of active dose of zinc oxide and stearic acid, when vulcanizing together with sulphur, decomposite
Biradical active sulfur or many base active sulfurs, can be crosslinked rubber molecule.
Vulcanization accelerator TMTD, rubber cement synthesis delayed action accelerator, is used in combination with zinc oxide, promotes with excellent vulcanization
Effect.
Channel black, rubber cement synthesis reinforcing agent, can increase the tensile strength and elongation of rubber cement, tear-proof and anti-
Cutting performance.
Liquid polyisobutene, with permanent adhesive, fabulous compatibility and resistance to ag(e)ing, can increase the low temperature of rubber cement
Flexibility and tack, extend storage period.
Rubber antiager RD, belongs to ketone amines antioxidants, and the protection to thermo-oxidative ageing is highly effective, the catalysis to metal
Oxidation also has extremely strong inhibitory action.
Rosin, rubber cement softening agent can increase rubber cement elasticity.
α pinene resin, with preferable heat endurance and electrical insulating property.
Beneficial effects of the present invention：
Preparation method is simple, easy to use；Rubber cement have to irregular surface it is good from shape, with various cable phases
Capacitive is good, has splendid adhesive property to copper, aluminium and cable sheath material, and temperature in use scope is wide -40 DEG C~+80 DEG C, no
It can be hardened, tear-resistant, water resistance is good, low-down water absorption rate；It can effectively seal and insulation processing power circuit contact, have
The effect of air-isolation, isolation moisture and insulation, protects the exposed line contacts in air or underground, is prevented effectively from line contacts
Oxidation electric leakage, contact resistance are excessive, it is ensured that power circuit service life, and reach insulation effect well.
