Description
Technical field
The invention belongs to adhesive technical field, and in particular to a kind of electrical apparatus insulation fluid sealant.
Background technology
In order to ensure the reliable and stable of motor, electric elements electrical property and mechanical strength, it is necessary between the conductors, gap with
And carry out insulated enclosure between outlet lead, various structural adhering and sealing of the electronic apparatus fluid sealant suitable for industrial production,
Such as：The structural bond of automobile bodies light plate, CRT kinescopes, wiring board, automobile headlamp washer sealing etc., but electronics at present
Electrical equipment caulking gum can discharge small molecule in the curing process, have minimal irritation to act on skin and eyes.
Meanwhile, existing fluid sealant is used primarily in electronic component, and electronic component is often in the work shape of high temperature
State, when the heat dispersion of fluid sealant is not good, can cause electronic component to be failed because local heating is too high, damaged, and existing
Fluid sealant in technology often only serve sealing and fixation, not only can not heat conduction well, also because of its thermal insulation more not
Beneficial to radiating；Therefore, existing fluid sealant how is improved, preferable heat dispersion is reached, is this area urgent need to resolve
Technical barrier.
The content of the invention
1. the invention technical problem to be solved
In view of the shortcomings of the prior art, the present invention provides a kind of electrical apparatus insulation fluid sealant, the cold-and-heat resistent alternation performance with brilliance,
Ageing-resistant performance and electrical insulation capability, can not produce pollution to electronic component sealing bonding effect and to surrounding enviroment.
2. technical scheme
The technical scheme is that：A kind of electrical apparatus insulation fluid sealant, is made up of the raw material of following parts by weight：Bisphenol-A epoxy
Resin 50-60 parts, water soluble phenol resin 30-35 parts, natural rubber 30-35 parts, methyl trichlorosilane 5-8 parts, diformazan
3-8 parts of base dichlorosilane, dioctyl phthalate 1-3 parts, pentalyn 5-10 parts, vinyl acetate 3-6 parts,
Silica flour 5-9 parts, calcium carbonate 4-8 parts, silica 2-5 parts, manganese dioxide 5-10 parts, carbon black 12-13 parts.
Further, also including following component：The mixture of sodium bicarbonate particle and carbon dust, and the particle diameter of the mixture is small
In 0.1mm.
Further, when the fluid sealant is just packed into position to be sealed, the hot blast blown out by hair-dryer is by fluid sealant
More than 50 DEG C are heated to, heating is stopped after continuing 30S.
3. beneficial effect
Compared with prior art, the invention has the advantages that：With remarkable cold-and-heat resistent alternation performance, ageing-resistant performance and electric insulation
Performance, can not produce pollution to electronic component sealing bonding effect and to surrounding enviroment.
Specific embodiment
The present invention is described in further detail with reference to specific embodiment.
Embodiment 1
A kind of electrical apparatus insulation fluid sealant, is made up of the raw material of following parts by weight：50 parts of bisphenol-A epoxy resin, water-soluble phenolic
30 parts of urea formaldehyde, 30 parts of natural rubber, 5 parts of methyl trichlorosilane, 3 parts of dimethyldichlorosilane, phthalic acid two are pungent
1 part of ester, 5 parts of pentalyn, 3 parts of vinyl acetate, 5 parts of silica flour, 4 parts of calcium carbonate, 2 parts of silica, dioxy
Change 5 parts of manganese, 12 parts of carbon black.
Embodiment 2
A kind of electrical apparatus insulation fluid sealant, is made up of the raw material of following parts by weight：55 parts of bisphenol-A epoxy resin, water-soluble phenolic
32 parts of urea formaldehyde, 32 parts of natural rubber, 6 parts of methyl trichlorosilane, 5 parts of dimethyldichlorosilane, phthalic acid two are pungent
2 parts of ester, 8 parts of pentalyn, 5 parts of vinyl acetate, 6 parts of silica flour, 5 parts of calcium carbonate, 4 parts of silica, dioxy
Change 8 parts of manganese, 12.5 parts of carbon black.
Embodiment 3
A kind of electrical apparatus insulation fluid sealant, is made up of the raw material of following parts by weight：60 parts of bisphenol-A epoxy resin, water-soluble phenolic
35 parts of urea formaldehyde, 35 parts of natural rubber, 8 parts of methyl trichlorosilane, 8 parts of dimethyldichlorosilane, phthalic acid two are pungent
3 parts of ester, 10 parts of pentalyn, 6 parts of vinyl acetate, 9 parts of silica flour, 8 parts of calcium carbonate, 5 parts of silica, two
10 parts of manganese oxide, 13 parts of carbon black.
Meanwhile, in the present embodiment, also including following component：The mixture of sodium bicarbonate particle and carbon dust, and the mixture
Particle diameter be less than 0.1mm.When the fluid sealant is just packed into position to be sealed, the hot blast blown out by hair-dryer is added fluid sealant
Heat stops heating to more than 50 DEG C after continuing 30S.Because solid sodium bicarbonate starts gradually to decompose generation dioxy more than 50 DEG C
Change carbon, generation of the carbon dioxide inside fluid sealant causes that fluid sealant is internally formed porous small ventilating structure, be conducive to close
The heat convection of sealing（Because above-mentioned ventilating structure is small, considerable influence can't be formed to the watertightness performance of fluid sealant）；Together
When, while fluid sealant internal porous ventilating structure is formed, a part of carbon dust can automatically be packed into the hole inside fluid sealant
In, toner passage is formed, so as to be internally formed the heat conduction via based on toner passage in fluid sealant, be conducive to fluid sealant
Heat transfer.By the addition of sodium bicarbonate particle above and toner mixture, the radiating mould inside fluid sealant can be effectively improved
Formula, significantly improves the radiating effect of fluid sealant, so as to provide a kind of novel seal gum for possessing good heat radiating function.（The present invention
It is directed to Application No.：The patent of CN 201510993324.4 is further improved）
The present invention is described by way of example above, but the invention is not restricted to above-mentioned specific embodiment, it is all based on this hair
Bright done any change or modification belong to the scope of protection of present invention.
