Description
Technical field
The present invention relates to polyurethane, polyureas technical fields, and in particular to a kind of light polyurethane-polyureas casting glue and its system
Preparation Method.
Background technology
With new energy revolution, chemical energy source will slowly be eliminated, before and after many countries have announced the year two thousand thirty in the world
Stop the production and sales of fuel oil automobile.The energy carrier that dynamic lithium battery will rapidly become automobile, and dynamic lithium battery
There is the active demand constantly promoted than energy, how safely and effectively to promote the energy density of lithium battery, be lithium battery production enterprise
The industry task of top priority.
There is a different explorations in present each enterprise of lithium battery group process, but with regard to current technology development path from the point of view of,
Soft-package battery is gradually favored because its is light-weight, energy density is high, improved safety by most enterprise, how into one
The safety that step improves battery is more and more important.
But gap of the current soft-package battery in assembling between the fixation of battery pack and battery pack, mostly using stent
Screw is added to fix, then is filled with expanded material.This structure still remains larger security risk, specially：Stent adds screw
Larger pressure can be caused to battery pack fixed position, and corresponding position cannot be generated in battery pack thermal expansion when fixed
It moves, while battery pack is required to have very high mechanical property in bracket fixture portions position, otherwise will be difficult to reach good fixed effect.
The fixed another method of battery pack is solved at present completes sky simultaneously for traditional organic silicon potting adhesive embedding fixation
Gap is filled, and this technique has good fixed effect, but traditional organic silicon potting adhesive is because of big (the generally 1.2-2.0g/ of density
cm3Left and right), it can cause battery weight that energy density decline is significantly increased in this way.Therefore, traditional organosilicon embedding how is solved
Glue causes battery weight to be significantly increased as a urgent problem to be solved.
Invention content
It is an object of the invention to be directed to problems of the prior art, a kind of light polyurethane-polyureas embedding is provided
Glue, it has lighting (≤1.0g/cm3), excellent chemical resistance, thermal conductivity or thermal insulation, anti-flammability and lighting
Etc. comprehensive performances, for the present invention using light filler, filler inherently has higher compression strength, therefore can effectively reduce
Set deformation volume caused by expanded material.
Another object of the present invention is to provide a kind of preparation method of light polyurethane-polyureas casting glue.
The purpose of the present invention is achieved through the following technical solutions：
A kind of light polyurethane-polyureas casting glue, is mixed with by the component of following parts by weight：
As preference, the sizing includes polyether polyol, polyester polyol, aspartate, isocyanic acid
It is arbitrary in ester, polyol isocyanate prepolymer, polyester isocyanate prepolymer, aspartate isocyanate prepolymer
One or more kinds of mixtures.
Wherein, the light filler is less than 1.0g/cm for density3Light material.
As preference, the light filler is micro- including glass hollow micro mist, aluminium oxide hollow powder, silicon dioxide hollow
Powder, any one in cinder micro mist or two or more mixtures.
As preference, the heat filling includes appointing in silica, aluminium oxide, silicon nitride, aluminium nitride, beryllium nitride
The mixture for one or more of anticipating, applied to insulating products.
As another preferred, the heat filling includes silicon carbide or metal fine powder, applied to nonisulated product.
As preference, the thermal insulating filling includes diatomite, precipitated calcium carbonate, talcum powder, mica powder, epoxy resin
Powder, plastics micro mist, expanded material micro mist in any one or two or more mixtures.
As preference, the fire retardant include aluminium hydroxide, magnesium hydroxide, melamine, ammonium polyphosphate, phosphate,
Any one in decabromodiphenylethane, antimony oxide or two or more mixtures.
As preference, the auxiliary agent includes any one in coupling agent, catalyst, antifoaming agent, levelling agent, plasticizer
Or two or more mixture.
A kind of preparation method of light polyurethane-polyureas casting glue, step are as follows：
1) 20-80 parts of aspartates, 10-60 parts of decabromodiphenylethane, 3-20 parts of antimony oxides are milled to
Fineness is spare as flame retardant intermediate less than 5um；
2) 20-70 parts of aspartates, 1-20 parts of silane coupling agents, 5-60 parts of aluminium nitride are placed in kneader,
Mediated at 120 DEG C it is agglomerating after, vacuum kneading 2 hours is down to room temperature naturally in sealing, spare as heat conduction intermediate；
3) by 10-60 parts of aspartates, 0.1-10 parts of plasticizer, 0.01-2 parts of defoaming levelling agents, 10-40 parts of resistances
Combustion intermediate, stirs evenly at 10-40 parts of heat conduction intermediates, lower that 5-30 parts of glass hollow micro mists are in batches slow mixing slowly
It adds in and stirs evenly, component A is made after vacuum defoamation；
4) B component will be made after 100 parts of hexamethylene diisocyanate polyether polyol prepolymer vacuum defoamations；
5) by the component A prepared and B component by weight 3：1 is uniformly mixed, and can be perfused after vacuum defoamation.
Relative to the prior art, beneficial effects of the present invention are：
Light polyurethane-polyureas casting glue of the present invention, it has lighting (≤1.0g/cm3), excellent chemically-resistant medicine
The comprehensive performances such as moral character, thermal conductivity or thermal insulation, anti-flammability and lighting, the present invention are inherently had using light filler, filler
There is higher compression strength, therefore the set deformation volume caused by expanded material can be effectively reduced.
