Description
Technical field
The present invention relates to the peripheral product of LEDbulb lamp, and in particular to the bulb lamp organosilicon that a kind of no spray is formed
It is bonded glue composition.
Background technology
With the development in pluralism of LEDbulb lamp, use range is more and more extensive, and use environment is also more and more diversified,
To waterproof, protection against the tide, dust-proof requirement also more and more higher under many environment, needed under many outdoor or adverse circumstances to LED ball
Steep lamp and carry out hermetically sealed protection.Organosilicon material has high-low temperature resistant, weather-resistant, electric insulation, resistance to ozone, hydrophobic, difficulty
Many excellent properties such as combustion, nontoxic, are widely used in LED adhering and sealing industries.Organosilicon for LEDbulb lamp sealing glues
Connecing glue mainly has de- ethanol system organosilicon sealant, de- oxime system organosilicon sealant, separating methanol system organosilicon sealant.
This three kinds of organosilicon sealants need to add more crosslinking agent, and ethanol system can release ethanol small molecule in solidification process, take off oxime
System can release ketoxime small molecule, and methanol system can release methanol small molecule, and these small molecules are under closed environment easily in ball
Bubble lampshade inwall is gathered into droplet, final products outward appearance and illumination effect is influenceed, so as to limit making for organosilicon sealant
With.
The content of the invention
The present invention assembles drop to solve the problems, such as that existing LEDbulb lamp seals small molecular, there is provided a kind of newly fogless
The bulb lamp organosilicon bonding glue composition that shape thing is formed.
The bulb lamp organosilicon bonding glue composition that a kind of no spray is formed, containing (A), (B) two components, (A),

0.05%~0.7%wt., and dimethyl siloxane ring body D3~D10 contents are less than 300ppm.
Drop is formed to the bulb lamp cover inwall of sealing in order to lower dimethyl siloxane ring body small molecule in 107 glue materials
Contribution, employ 107 silicon rubber of 1500~10000mpa.s range of viscosities, 107 silicon rubber of this range of viscosities can be with
This target is realized well.But even compared with low viscosity α, the dimethyl siloxane ring of alpha, omega-dihydroxy polydimethyl siloxane
Body D3~D10 contents are controlled within 300ppm, and traditional polycondensation type organosilicon systems, which need to add more crosslinking agent, to be solidified,
Also more small molecule can be released in solidification process, small molecule is in sealed states and then aggregation forms droplet, therefore, the present invention
Effectively introduce methyl hydrogen siloxane and make crosslinking agent, trace hydrogen is released in solidification process, but trace hydrogen moves to bulb lamp cover
Inwall will not be agglomerated into liquid spray, and methyl hydrogen siloxane its range of viscosities that the present invention selects is 110~120mpa.s, its
Hydrogen content is 0.05%~0.7%wt., and dimethyl siloxane ring body D3~D10 contents are less than 300ppm.Thus effectively keep away
The problem of being focused into drop with small molecule of hazing is exempted from.
Another preferred scheme is that the particle size range of the precipitated calcium carbonate of the surface treatment is 0.06~0.09 μm.
Another preferred scheme is the surface hydrophobicity fumed silica, and its surface hydrophobicity inorganic agent is hexamethyl two
One or more in silazane, vinyltrimethoxy silane, stearic acid.
Another preferred scheme is, the viscosity of the dimethyl polysiloxane is 10~20mpa.s, and dimethyl siloxane ring

Another preferred scheme is that described tin catalyst is dibutyl tin laurate.
Tackifier are N, and N- dimethyl-APTES, such tackifier are tertiary amine, are catalyzed with tin class
Agent, which can stablize, to be coexisted, while plays a part of increasing bonding force and catalytic promoter.
The present invention, which provides one kind and is different from conventional condensation type organosilicon sealant, to be had in the curing process without can be gathered into
The bulb lamp bonded adhesives that liquid small molecule is released.In use, A, B component are most preferably with 10：1 mass ratio is well mixed, Ran Houyong
Spot gluing equipment is played glue in bulb lamp seat groove, then lampshade is enclosed in lamp socket groove, and room temperature steeps ball after placing two hours
Lamp lights aging twenty four hours, and gained sealing elastomer tool good airproof performance, toughness is high, waterproof and dampproof excellent performance, and ball steeps
Lamp inwall is formed without vaporific droplet.
