Abstract
The invention relates to a heat conducting and flame retardant pouring sealant, which includes a component A and a component B in a ratio of 1:1. Every 100 parts by weight of the component A comprises: 30-80 parts of alumina, 0.5-1 part of a curing agent, and the balance silicone rubber; and every 100 parts by weight of the component B comprises 50-70 parts of aluminum hydroxide, 5-10 parts of a crosslinking agent, 0.2-0.6 part of a delay agent, and the balance silicone rubber. According to the invention, alumina is utilized to improve the heat conductivity coefficient of the pouring sealant, aluminum hydroxide improves the flame retardant grade, and the curing agent improves the resistance to poisoning. With weak settleability, the heat conducting and flame retardant pouring sealant is applicable to packaging of a driving power supply in LED bubble lamps.
Description
Technical field
The present invention relates to LED joint sealant technical field, the heat conductive flame-retarding joint sealant that particularly good, the anti-toxic of a kind of heat conductive flame-retarding is good, settleability is weak.
Background technology
LED is the abbreviation of photodiode, has energy-saving and environmental protection, without the advantage such as stroboscopic, long service life for light fixture.LEDbulb lamp is the LED of conventional spherical form, and what its internal light source was selected is LED lamp bead.What the cost of ball bubble was the highest can be described as driving power, and do not have this to drive, lamp pearl can not be bright.Bulb lamp operationally, usually can cause fault because driving power is overheated.At present, although there is various solution on the market, effect is all undesirable.Such as: use the whole power supply of heat-shrink tube package, although certain insulating effect can be played, do not play certain radiating effect; Use common joint sealant, although the effect be adhesively fixed can be played, run into high temperature and just can melt, easily come off, even burn.
Therefore need to provide a kind of new heat conductive flame-retarding joint sealant to solve above problem.
Summary of the invention
Main purpose of the present invention is to provide the heat conductive flame-retarding joint sealant that good, the anti-toxic of a kind of heat conductive flame-retarding is good, settleability is weak.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of heat conductive flame-retarding joint sealant, comprises component A and the B component of 1:1:
Every 100 weight part component A proportionings are aluminum oxide 30-80 part, solidifying agent 0.5-1 part, and all the other are silicon rubber;
Every 100 weight part B component proportionings are aluminium hydroxide 50-70 part, linking agent 5-10 part, and delayed-action activator 0.2-0.6 part, all the other are silicon rubber.
Concrete, described silicon rubber is room temperature vulcanized sili cone rubber.
Further, described silicon rubber is vinylsiloxane rubber.
Concrete, described aluminum oxide is AR-10 type aluminum oxide.
Concrete, described solidifying agent is platinum complex.
Concrete, described linking agent is CG03 type linking agent.
Concrete, described delayed-action activator is D4 type delayed-action activator.
