Description
Technical field
The present invention relates to fluid sealant field, and in particular to a kind of polyurethane sealant.
Background technology
Silylated polyurethane has the advantage of polyurethane and organosilicon material concurrently, with wet-heat resisting, oil resistant, chemicals-resistant, resistance to
Performance and good storage stability are ground, is with a wide range of applications in automobile, building and electronic applications.But due to silanization
Polyurethane self-strength is not high, if for preparing fluid sealant, it is necessary to add reinforced filling.Addition filler can improve fluid sealant
Physical property, have great importance while reducing cost.Because nano material has unique quantum size effect, surface
With interfacial effect and small-size effect, therefore with the physics characteristic not available for many macroscopic materials.
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 because local heating is too high and fails, damage, 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
Present invention aims at high, good sealing effect, the low fluid sealant of cost there is provided a kind of intensity.
2. technical scheme
A kind of polyurethane sealant, it is characterised in that mixed by weight percentage by following components：
30-50 parts of silylated polyurethane
35-55 parts of filler
5-15 parts of plasticizer
.5 parts of 1 .5-3 of catalyst
.5 parts of 1 .5-3 of deicer.
Further, described filler is nano-calcium carbonate.
Further, described plasticizer is diisooctyl phthalate.
Further, described catalyst is dibutyl tin laurate.
Further, in addition to 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, continues to stop heating after 30S.
3. beneficial effect
The present invention is relative to the beneficial effect of prior art：The polyurethane sealant of the present invention, has used silylated polyurethane,
It has the advantage of polyurethane and organosilicon material concurrently, with wet-heat resisting, oil resistant, chemicals-resistant, anti-wear performance and good storage
Stability.Nano-calcium carbonate is with the addition of in component simultaneously, it has good reinforcing effect to silylated polyurethane, of the invention is poly-
Urethane fluid sealant items good combination property, cost is low, with good economic and social benefit.
Embodiment
The technique effect of design and the generation of the present invention is clearly and completely described below with reference to embodiment, with
It is completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is the part implementation of the present invention
Example, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not before creative work is paid
Obtained other embodiment is put, the scope of protection of the invention is belonged to.
Embodiment 1：
A kind of polyurethane sealant, is mixed by weight percentage by following components：
40 parts of silylated polyurethane
45 parts of filler
10 parts of plasticizer
.5 parts of catalyst 2
.5 parts of deicer 2.
Embodiment 2：
A kind of polyurethane sealant, is mixed by weight percentage by following components：
40 parts of silylated polyurethane
47 parts of nano-calcium carbonate
8 parts of diisooctyl phthalate
2 parts of dibutyl tin laurate
3 parts of deicer.
Meanwhile, in the present embodiment, in addition to 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 adds fluid sealant
Heat continues to stop heating after 30S to more than 50 DEG C.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 fluid sealant to be 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 be packed into the hole inside fluid sealant automatically
In, toner passage is formed, so as to be internally formed the heat conduction via based on toner passage in fluid sealant, is 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 to be directed to Application No.：CN201610187244.4 patent is further improved）
The better embodiment to the present invention is illustrated above, but the invention is not limited to the embodiment,
Those skilled in the art can also make a variety of equivalent modifications or replacement on the premise of without prejudice to spirit of the invention, this
Equivalent modification or replacement are all contained in the application claim limited range a bit.
