Technical field
The invention belongs to chemical pump airtight and watertight padding field, and in particular to one kind is without asbestos chemical pump airtight and watertight padding.
Background technology
Packing seal is also known as gland packing sealing, also referred to as packing_seal.Packing seal has relatively simple for structure, cost
The features such as low, plant maintenance facilitates, thus be widely used.When conveying slurry, a large amount of pump apparatus need to be used, this kind equipment is carried out
Dynamic sealing and Fillers selection work, packing seal can be made to play maximum effect, so as to ensure to produce stable operation.Filler is close
Envelope is general to use oil immersion asbestos packing or oil immersion cotton yarn filler.But recently as the raising of environmental requirement, because asbestos are filled out
Material can produce very big pollution during production and use, and harm can be produced to the health of human body, therefore be badly in need of a kind of
More environmentally-friendly, significant sealing affection without asbestos chemical pump airtight and watertight padding.
The content of the invention
In order to solve the above problems, the present invention provides one kind without asbestos chemical pump airtight and watertight padding.
The present invention is achieved by the following technical solutions.
One kind is made up without asbestos chemical pump airtight and watertight padding of the component of following parts by weight：45-50 parts of carbon fiber, acetic acid are fine
Tie up 15-20 parts of element, 5-8 parts of 1,8- pungent two mercaptan, 3-6 parts of perfluorinated biphenyl, 11-15 parts of polymethyl methacrylate, xanthans 10-
13 parts, 1-3 parts of behenyl acid amides, 2-5 parts of calcium carbonate, 0.9-1.2 parts of aluminum oxide, 0.8-1.2 parts of magnesia, 22-26 parts of lubricating oil,
Preparation method includes following operating procedure：（1）Carbon fiber and surface of cellulose acetate are uniformly sprinkled with a small amount of volume fraction
For 3% hydrochloric acid solution, after 3-5min, the hydrochloric acid solution on net surface is cleaned using clear water；（2）Step will be passed through（1）The carbon of processing
Fiber is put into cellulose acetate in the diethyl ether solution that volume fraction is 50%, dibenzoyl peroxide is then added thereto, instead
Answer after 20-25min, take out modified carbon fiber and cellulose acetate, dry；（3）By obtained modified carbon fiber and acetic acid
Cellulose and pungent two mercaptan of 1,8-, perfluorinated biphenyl, polymethyl methacrylate, xanthans, behenyl acid amides, calcium carbonate, aluminum oxide,
Magnesia is added in mixer together, after middling speed is mixed 2-3 hours, is put into 45-50 DEG C of baking oven and is dried after 70-100min,
Lubricating oil, finished product are added thereto.
Specifically, the Average Particle Diameters of above-mentioned xanthans are 70 mesh, and the active constituent content of above-mentioned behenyl acid amides is
98.5%。
Specifically, above-mentioned steps（2）The solid-to-liquid ratio of middle carbon fiber and cellulose acetate and diethyl ether solution is 1:5, peroxidating
The addition of dibenzoyl is carbon fiber and 0.03 times of weight of cellulose acetate gross weight.
Technical scheme more than, the beneficial effects of the invention are as follows：
The present invention provide without asbestos chemical pump airtight and watertight padding, will not be to environment and operator during production and use
The health of member, which is produced, to endanger, the airtight and watertight padding that the present invention is provided, and significantly, chemical stability is good, and pump shaft is caused for heat-transfer effect
Damage it is smaller, can effectively extend the service life of pump shaft.Wherein, carbon fiber passes through modification with cellulose acetate
Afterwards, the good modified fibre of loose soft flexible is formd, after being used as filler, elasticity is good, has 75% time in its thickness direction
Elasticity, the lubricating oil that can be effectively protected in axle sleeve, and filler is easy to form non-breakable, equal in filler and boss surfaces
The oil film of even distribution, can effectively prevent the dry friction of axle；Pungent two mercaptan of 1,8-, perfluorinated biphenyl, polymethyl methacrylate association
It after same-action, can enable filler that there is great surface, can effectively prevent the infiltration of porous medium, and then improve filler
Sealing effectiveness；After xanthans, behenyl acid amides, calcium carbonate, aluminum oxide, magnesia synergy, filler is greatly improved
Heat transfer property and heat endurance, and the ability of the anti-chemical corrosion of filler is improved, it is effectively prevented filler relaxation powder
Change, ask that gap expansion and seal pressure decline the generation of phenomenon, extend the service life of filler.
