Abstract
The present invention belongs to strippability, rust-preventing characteristic, insulativity sealing material.The present invention mixes at normal temperatures by a certain percentage with supervinyi chloride resin, white carbon black, Resins, epoxy, dibutyl phthalate, dodecenylsuccinic acid, acetone, dimethylbenzene.Characteristics such as the present invention has that performance is good, applied range, manufacture craft are simple.
Description
The present invention belongs to strippability, rust-preventing characteristic, insulativity sealing material.
The end of various mechanical means parts becomes, the thread connection place, because the material quality, the restriction of conditions such as working accuracy, installation and maintenance level exists leakage problems always.Traditional sealed solid material as metal, rubber, asbestos, plastics etc., exists the defective that solid materials such as compression set, internal stress, elastic fatigue are difficult to overcome, and can't satisfy more and more higher seal request.In recent years.Though occurred various Fluid Sealgums on the market, in use ubiquity easily embrittlement, difficulty is peeled off, and the disadvantage of secondary maintenance difficult in use is restricted.
Purpose of the present invention is exactly at the problems referred to above, provides a kind of strippable, makes things convenient for the secondary maintenance, and has rustless property, the sealing agent of insulating property.
The object of the present invention is achieved like this, in conjunction with China's national situation, adopts domestic raw material, mainly is that supervinyi chloride resin, white carbon black and corresponding solvent thereof, additive are formulated in proportion.
Novel strippability sealing agent of the present invention is a kind of colloid.When being coated in trim, after the solvent evaporates, on trim, form a kind of certain elasticity that has, the Hookean body film of higher-strength, this film strength makes its characteristics with strippability greater than its cohesive force, has rustless property and electrical insulation capability simultaneously.
Main materials proportioning of the present invention (weight) is as follows:
The weight percent of supervinyi chloride resin, white carbon black (white carbon black that vapor phase process is produced for No. 1), Resins, epoxy (E44-6101), dibutyl phthalate, dodecenylsuccinic acid (T746), acetone, dimethylbenzene is 20-27: 5-5.4: 0.02-0.12: 0.02-0.12: 0.02-0.5: 40.5-50: 24.94-26.36.
Basic material selects for use chlorinated polyvinyl chloride (CPVC) with acetone solution (perhaps using other ketones solvents), and solvent ratio is between 1.5-2.5.Supervinyi chloride resin is a kind of good filmogen, but insufficient strength packing technique conditional request after the film forming is broken when peeling off easily.For this reason, add a kind of strengthening agent-white carbon black (vapor phase process production), add-on is 0.15-0.25 a times of chlorinated polyvinyl chloride, makees wetting agent with suitable aromatic hydrocarbon solvent again and calls in the chlorinated polyvinyl chloride base-material.In order to increase rustless property, add dodecenylsuccinic acid (T746), add-on is the 0.02-0.5% of output, and adds suitable tackifier, softening agent.The present invention keeps its strippability, has rust-preventing characteristic simultaneously, and electrical insulating property possesses the bounding force that is not less than 0.4MPa again.
Major advantage of the present invention:
1, performance is good:
Salient features data through Dalian sealing agent of the present invention that materialization detects are as follows:
1) total solids is no less than 40%
2) cohesive strength is not less than 0.4Mpa
3) anti-sulfuric acid (65 ± 4 ℃) did not have corrosion in 4 hours
4) alkaline-resisting (65 ± 4 ℃) did not have corrosion in 4 hours
5) anti-solvent oil (65 ± 4 ℃) did not have corrosion in 4 hours
6) has strippability
7) the breakdown voltage resistant 80KW/mm that is not less than
8) the withstand voltage 7Mpa that is not less than of stopping property.
2, applied range
This product is a viscous liquid, and the every CM of velocity of flow is 7-8S.Employing lead pipe packing.
Its characteristics of this product have strippability, are convenient to the secondary maintenance of various mechanical means.The melts combine face there is rust-preventing characteristic.Electrical equipment is provided with good insulativity, is applicable to following occasion:
1) the casing bonding surface of the fuel tank of mechanical means, wheel casing, water tank;
Joint flange end face, screw thread in the pipeline of chemical mediums such as 2) various oil transportations, water delivery, defeated vapour and acid, alkali;
3) hydraulic efficiency system;
4) cylinder body and cylinder caps such as the engine of carrier vehicle, aircraft, boats and ships, air compressor;
5) transformer, motor, conditioner, refrigerator and refrigerator equipment such as (fluorine Lyons delivery systems);
6) valve.
3, manufacture craft is simple, concocts under normal temperature, normal pressure, need not heating installation, does not have the three-waste pollution problem.
