Description
Technical field
The present invention relates to organosilicon material field, specially a kind of preparation of two component clear LED organosilicon coating glue.
Background technique
Light-emitting diode display integrates microelectric technique, computer technology, information processing, dynamic model bright in luster with its
Enclose that wide, brightness is high, clarity is high, operating voltage is low, small power consumption, service life length, impact resistance, beautiful in colour and stable and reliable in work etc.
Advantage becomes a new generation's display media of most advantage.Light-emitting diode display is widely used to large-scale square, commercial advertisement, sport
The various places such as venue, information propagation, news briefing, securities trading.Wherein, LED display mould group be composition LED display at
One of main component of product is mainly made of LED light, PCB circuit board, driving IC, resistance, capacitor and plastics external member.According to making
With the difference of LED packaging, LED display mould splits are as follows: straight cutting lamp LED display mould group, indoor lattice LED display screen mould
Group, surface mounted LED display screen mould group.For better conform to the indoor and outdoor use environment of various differences and extend product use the longevity
Life, LED display mould group needs to protect its LED light, PCB circuit board when preparing, and epoxy pouring sealant, organosilicon encapsulating
Glue is then most common two kinds of protected modes.
Epoxy resin embedding adhesive is long there are curing time, hardness is high, temperature tolerance and moisture-proof are poor, high-low temperature resistant alternating
Variation performance is poor and a series of deficiencies such as reprocess inconvenience, and therefore, LED display mould group usually all selects organosilicon encapsulating
Glue protects LED light and PCB circuit board.Organic silicon potting adhesive is typically all soft elastomeric, have excellent insulating properties,
Weatherability, optical property, waterproofness and resistant of high or low temperature have a wide range of applications in Electronic Packaging field.
It is applied to the organic silicon potting adhesive of LED display mould group protection currently on the market with bicomponent black condensed type LED
Organic silicon potting adhesive is in the majority, but organic silicon potting adhesive dosage required for the program is bigger is unfavorable for save the cost, and
Part silicone casting glue product deposit at high or low temperatures can bleed, pollute external member, or even to plastics external member have corrosion etc.
Many deficiencies.With the needs of the upgrading of LED display mould set product and cost control, surface mounted LED display screen mould group is just
The straight cutting lamp LED display mould group of mainstream is accounted for before gradually replacing, what is changed correspondingly is glue-applying technique also just from filling before
Envelope glue-applying technique is gradually converted into spraying applications technique.Surface Mount technique saved the manufacturing cost of LED display mould group while
Saved protective glue usage amount, saved the product cost of LED display mould group to greatest extent, improve product cost and
Market competition advantage.With the rise of surface mounted LED display screen mould group, conventional bicomponent black condensation type LED organic silicon potting adhesive
It will gradually be substituted by transparent coating glue, and there are viscosity for the popular more two component clear organic silicon potting adhesive in market at present
It is higher to be unable to satisfy some shortcomingss such as spraying applications technique and cementability and yellowing resistance deficiency, meanwhile, current is double
Component organic silicon potting adhesive crosslinking curing requires organotin as crosslinking catalyst, and organotin belongs to heavy metal, is unfavorable for
Environmental protection, the present invention are prepared for a kind of compound tackifier and have both catalytic crosslinking and promote the function of bonding, can be effectively reduced
The dosage of machine tin catalyst also can achieve the effect of crosslinking curing even without catalyst.Therefore, meaning of the present invention is
Develop that a kind of low viscosity, the transparency is good, elasticity is good, cementability is good, yellowing resistance is good, good weatherability, non-corrosive, environment friend
It is good, and can satisfy the new LED display mould group protective glue of spraying applications technique.
