As the acrylate oligomer, various types of acrylate oligomers such as urethane acrylate oligomers, polyester acrylate oligomers, and epoxy acrylate oligomers may be used.

Here, the amount of the acrylate oligomer used is preferably 10 to 50 parts by weight based on the total weight of the acrylate mixture, and when less than 10 parts by weight is used, the viscosity is low, so it is difficult to control the coating thickness, and when used in excess of 50 parts by weight, the viscosity becomes too high There is a disadvantage in that the adhesive strength is lowered.

The UV-curable organic-inorganic hybrid compound may be a compound including nano silica and an acryl group.

Here, it is preferable to use 1 to 10 parts by weight of the UV-curable organic-inorganic (silica-acrylic) hybrid compound with respect to 100 parts by weight of the acrylate mixture. When it exceeds, heat resistance and re-peelability are excellent, but the adhesive strength is deteriorated.

The photoinitiator is preferably used in an amount of 0.1 to 3 parts by weight based on 100 parts by weight of the acrylate compound, and when the content is less than 0.1 parts by weight, the polymerization rate is slow and the conversion rate is low, and when used in excess of 3 parts by weight, the reaction rate is Although it is fast, there are many oligomers of low molecular weight, and the physical properties of the adhesive are deteriorated.

Here, the types of photoinitiators include benzophenone, benzion, benzionmethyl ether, benzion-n-butyl ether, benzion-iso-butyl ether, 1-hydroxycyclohexyl phenyl ketone, 2,2-diethoxyacetophenone. , acetophenone, methylphenyl glyoxylate, ethylphenylphylloxylate, and the like, and can be used alone or in combination of two or more.

The heat conduction filler is mixed with a polymer so that when it is attached to the connection part of the LED substrate and the electric wire or the fire extinguishing sheet, heat is transferred from the connection part of the LED substrate and the electric wire to the fire extinguishing sheet. a first filler having a second average particle diameter, a second filler having a second average particle diameter, and a third filler having a third average particle diameter, wherein the first average particle diameter is 10 to 30 μm, which is larger than the other average particle diameters, and the second average A value obtained by dividing a particle size value by the first average particle size value is 0.17 to 0.26, and a value obtained by dividing the third average particle size value by the first average particle size value is 0.09 to 0.11, and the first filler, the second filler, and the third filler The volume resistance is 10 ⁴ Ωcm or more, the first filler, the second filler, and the third filler have an average value of minor/major axis of 0.6 to 0.8, and the percentage of the sum of the masses of the second fillers/sum of the mass of the first filler is 11 to 16 or the percentage of the sum of the masses of the third fillers/the sum of the masses of the primary fillers is 4.2 to 5.2.

The primary, secondary and tertiary fillers are alumina (Al2O3), boron nitride (BN), aluminum nitride (AlN), silicon nitride (Si3N4), magnesia (MgO), beryllia (BeO), zinc oxide (ZnO) ), silicon carbide (SiC), zirconia (ZrO2), and mixtures thereof.

Here, the first filler, as the largest filler among the fillers, has an average particle diameter in the range of 10 to 30 μm. If it is out of the above range, it cannot maintain an appropriate viscosity range when mixed with the polymer, so the surface of the fire extinguishing sheet Since it cannot be kept smooth, it is good to have the above critical significance.

In addition, the second filler fills the space between the polymer and the first filler, and the value obtained by dividing the second average particle diameter by the first average particle diameter has an average particle diameter corresponding to 0.17 to 0.26. If it does not have a particle size, it is not possible to contact the first filler and is spaced apart, so that heat dissipation characteristics may be deteriorated, so it is preferable to have the critical significance as described above.

In addition, the third filler fills the space between the first filler and the second filler, and a value obtained by dividing the third average particle diameter by the first average particle diameter has an average particle diameter corresponding to 0.09 to 0.11, If it does not have the same average particle diameter as the above, it is preferable to have the critical significance as described above because the heat dissipation characteristic may be deteriorated due to the separation without contact with the first filler.

In addition, the volume resistance of the first filler, the second filler and the third filler is preferably 10 ⁴ Ωcm or more, and if the volume resistance is less than 10 ⁴ Ωcm, a short circuit occurs when a current is applied to the surface of the fire extinguishing sheet Since there is a problem, it is good to have the critical significance as described above.

In addition, the first filler, the second filler, and the third filler preferably have an average value of the minor axis/long diameter of 0.6 to 0.8. Since heat dissipation characteristics may be deteriorated because

In addition, it is preferable that the percentage of the sum of the masses of the second fillers/the sum of the masses of the first fillers is 11 to 16, or the percentage of the sum of the masses of the third fillers/the sum of the masses of the first fillers is 4.2 to 5.2, and the mass ratio as above If not, the small filler is not added only enough to fill the space formed by the large filler, but a large amount or a small amount is added so that the large fillers are spaced apart and the heat dissipation characteristics may be deteriorated, so it is good to have the above critical significance.

Here, 60 to 80 parts by weight of the filler for heat conduction is added and mixed with respect to 100 parts by weight of the polymer. When it is less than 60 parts by weight, the rate of absorbing heat becomes slow, and when it exceeds 80 parts by weight, the polymer and Since the stirrability of the sintering property is greatly reduced, the workability is lowered, and the surface finish is lowered, it is good to have the critical significance as described above.

The flame retardant suppresses combustion of the first heat dissipating adhesive or the second heat dissipating adhesive due to high temperature heat and thermal conductivity when attached to the connection portion of the LED substrate and the electric wire, and may include methyl iodide and the like.

Here, 20 to 40 parts by weight of the flame retardant is added and mixed with respect to 100 parts by weight of the polymer, but when it is less than 20 parts by weight, moisture retention, moisture permeability and thermal conductivity are lowered to lower the flame retardant function, and when it exceeds 40 parts by weight, Since a floating shape is generated and moisture permeability is rather reduced, it is good to have the critical significance as described above.

In the first heat-dissipating adhesive layer, the first heat-dissipating adhesive is an adhesive means to adhere to an LED substrate or the like together with a heat-dissipating agent or to be easily peeled off from the LED substrate, etc. 0.2 to 0.3 parts by weight of a curing agent.

The rubber-type adhesive has a predetermined elasticity and provides an adsorption and adhesion function, and when mixed with a heat curing agent and a room temperature curing agent, it is stably attached to the adherend surface, and a second heat dissipation adhesive layer described later so that no residue is left when peeled from the adherend surface and make it adhere with stronger adhesive force.

Here, since the rubber-type pressure-sensitive adhesive preferably contains 38% of solid content and may have a known composition, a detailed description thereof will be omitted.

Heat curing agent is a hardening member that reacts with rubber-type pressure-sensitive adhesives or room-temperature curing agents when mixed with them to improve overall physical properties such as improved impact resistance and heat resistance, moisture resistance and mechanical properties. to 1.3 parts by weight are added, and if it exceeds 1.3 parts by weight, the curing time is too fast and the application to the second heat dissipation adhesive layer is inconvenient, and if it is less than 1.1 parts by weight, the curing time is too slow and the adhesive feet become longer after a long time. Since there is a problem that is, it is preferable to have the critical significance as described above.

Here, since the heat curing agent may have a known composition, a detailed description thereof will be omitted.

The room temperature curing agent reacts with the rubber-type adhesive or heat curing agent when mixed with them so that the mixture is cured at room temperature to prevent the rubber-type adhesive and heat curing agent from spreading to the outside of the adhesive surface. As a transfer preventing member, a rubber-type adhesive 0.2 to 0.4 parts by weight of a heat dissipating adhesive is added to 100 parts by weight, and when it exceeds 0.4 parts by weight, the curing time at room temperature proceeds quickly, and the usable time of the product is greatly shortened. Since there is a problem in that the type pressure-sensitive adhesive and the heat curing agent are spread, it is preferable to have the critical significance as described above.

On the other hand, in the first heat dissipation adhesive layer of the present invention, the heat dissipation agent and the first heat dissipation adhesive having the above configuration are mixed in a volume ratio of 2:1 to 3:1. Difficulty in controlling post-curing time and weight average molecular weight occurs, and cracks occur due to poor curing, lifting, and deterioration of physical properties. good to have

Therefore, according to the first heat dissipation adhesive layer, when it is attached to the surface of the LED substrate, the heat of the LED substrate, etc. can be quickly transferred to the fire extinguishing sheet for heat dissipation. 2 Because it has a strong adhesion to the heat dissipation adhesive layer, it can be peeled off without leaving any residue on the LED substrate, etc., so that it can be attached to the new LED substrate as it is.

In the second heat-dissipating adhesive layer, the second heat-dissipating adhesive is applied to the fire-fighting sheet together with the heat-dissipating agent or when peeled from the LED substrate, etc. As an adhesive means that provides strong adhesive strength so that the first heat-dissipating adhesive layer is easily peeled from the LED substrate, etc., To 100 parts by weight of the composite in which PVC resin, polyoxyethylene alkyl ether and methyl oleate are mixed, 100 parts by weight of the composite is 60 to 80 parts by weight of the heat dissipating adhesive N-2,4-dinitrophenylserine, 50 parts by weight of benzylchloroformate to 70 parts by weight, 40 to 60 parts by weight of an aqueous polyurethane thickener, 30 to 50 parts by weight of dicyclohexylurea, 20 to 40 parts by weight of 1,1,2,2-tetrabromoethane, 10 to 30 parts by weight of dioctylphthalate and 5 to 15 parts by weight of dibutylphthalate.

Tensile strength and weather resistance are properly maintained, polyoxyethylene alkyl ether functions as a diluent to maintain a gel state after mixing the compositions, and methyl oleate functions as a plasticizer.

N-2,4-dinitrophenylserine provides water resistance and abrasion resistance to the radiator by dissolving the compositions of the second heat dissipating adhesive to have a high bonding force with each other.

Here, in N-2,4-dinitrophenylserine, 60 to 80 parts by weight of the heat dissipating adhesive is mixed with 100 parts by weight of the composite. It is lowered, and when it is less than the above weight part, there is a problem that the reaction rate of the compositions becomes too slow and the stirring time increases, so it is good to have the critical significance as described above.

Benzylchloroformate is mixed with the compositions to control the reactivity of the compositions.

Here, benzylchloroformate is mixed in 50 to 70 parts by weight based on 100 parts by weight of the composite. When it exceeds the above weight, it has a rapid reactivity and cannot be mixed at normal room temperature, so many restrictions are generated in the coating operation. , when the amount is less than the above weight part, since the reactivity is rapidly reduced and a lot of time is required for the stirring operation, it is good to have the critical significance as described above.

The water-based polyurethane thickener provides a thickening function so that the heat dissipating agent particles are well present by making the dispersion process of the compositions good when mixed with the heat dissipating agent.

Here, 40 to 60 parts by weight of the aqueous polyurethane thickener are mixed based on 100 parts by weight of the composite, and when it exceeds the above parts by weight, the heat dissipating agent composition and stirring efficiency are reduced, and when it is less than the above weight parts, the heat dissipating agent composition Since there is a problem in that the particles do not have a good state and adhesion is deteriorated, it is good to have the critical significance as described above.

Dicyclohexylurea is mixed with the above compositions to provide a coating layer.

Here, the dicyclohexyl urea is mixed in 30 to 50 parts by weight based on 100 parts by weight of the composite. When the amount exceeds the weight part, the viscosity becomes too large to decrease the adhesiveness, and when it is less than the weight part, the adhesiveness is reduced. Since there is a problem in that the strength is lowered and the adhesive performance with the fire extinguishing sheet is lowered, it is good to have the critical significance as described above.

1,1,2,2-Tetrabromoethane, when mixed with the compositions, determines the reaction time of the compositions and provides an adsorption function.

Here, 1,1,2,2-tetrabromoethane is mixed in 20 to 40 parts by weight based on 100 parts by weight of the composite. And at the same time as the adhesion is lowered, the reaction termination of the compositions is rapid, so that the adsorption and adhesion function with the first heat-dissipating adhesive layer is lowered. Since there is a problem in that the adhesion function is also deteriorated, it is good to have the critical significance as described above.

Dioctyl phthalate provides improved tensile strength and elongation through a plasticizer function when mixed with the above compositions.

Here, 10 to 30 parts by weight of dioctyl phthalate is mixed based on 100 parts by weight of the composite. When it exceeds the above weight part, tensile strength and elongation are rather reduced, and when it is less than the above weight part, the plasticity performance is lowered and Since there is a problem of lowering the adhesive strength, it is preferable to have a limited weight part as described above.

Dibutyl phthalate provides a plasticizer function together with the dioctyl phthalate.

Here, dibutyl phthalate is mixed in 5 to 15 parts by weight based on 100 parts by weight of the composite. When it exceeds the above parts by weight, tensile strength and elongation are rather reduced, and when it is less than the above parts by weight, the plasticity performance is lowered, and Since there is a problem of delay in curing time and deterioration in adhesive strength, it is preferable to have the limited parts by weight as described above.

On the other hand, in the second heat dissipation adhesive layer of the present invention, the heat dissipation agent and the second heat dissipation adhesive of the above configuration are mixed in a volume ratio of 1:1 to 2:1. Since it is difficult to control the post-curing time and control the weight average molecular weight, cracks occur due to poor curing, lifting, and deterioration of physical properties, thereby reducing thermal conductivity, so it is good to have the above critical significance.

Therefore, according to the second heat dissipation adhesive layer, when applied and attached to the surface of the fire extinguishing sheet, the heat transferred from the first heat dissipating adhesive layer can be quickly radiated into the air, and the fire extinguishing sheet is removed from the LED substrate for maintenance. In this case, the first heat dissipation adhesive layer is peeled off without leaving any residue on the LED substrate as it is adhered to the fire extinguishing sheet while having a stronger adhesive force than the first heat dissipation adhesive layer, so that it is attached to the new LED substrate as it is, and reusability can be improved.

As the molecular weight modifier, a compound containing a thiol (-SH) group is used, and ethyl mercaptan, butyl mercaptan, hexyl mercaptan, dodecyl mercaptan, phenyl mercaptan, benzyl mercaptan, etc. are 0.01 parts by weight based on 100 parts by weight of the acrylate compound. It is preferable to use from 1 part by weight to, when the content is less than 0.01 part by weight, it is difficult to control the molecular weight, and when it exceeds 1 part by weight, the molecular weight is too low to deteriorate the final physical properties.

The filler for heat conduction is mixed with a polymer so that the heat transferred from the second heat dissipation adhesive layer is quickly diffused into the air when applied or coated on the fire extinguishing sheet. including a second filler having a The divided value is 0.17 to 0.26, the third average particle diameter value divided by the first average particle diameter value is 0.09 to 0.11, and the volume resistance of the first filler, the second filler and the third filler is 10 ⁴ Ωcm or more, the first filler, the second filler and the third filler have an average value of minor axis/major axis of 0.6 to 0.8, and the percentage of the sum of the masses of the secondary fillers/the sum of the masses of the first fillers is 11 to 16 or the sum of the masses of the third fillers The percentage of the sum of the masses of /first fillers is between 4.2 and 5.2.

The primary, secondary and tertiary fillers are alumina (Al2O3), boron nitride (BN), aluminum nitride (AlN), silicon nitride (Si3N4), magnesia (MgO), beryllia (BeO), zinc oxide (ZnO) ), silicon carbide (SiC), zirconia (ZrO2), and mixtures thereof.

Here, the first filler, as the largest filler among the fillers, has an average particle diameter in the range of 10 to 30 μm. If it is out of the above range, it cannot maintain an appropriate viscosity range when mixed with the polymer, so the surface of the fire extinguishing sheet Since it cannot be kept smooth, it is good to have the above critical significance.

In addition, the second filler fills the space between the polymer and the first filler, and the value obtained by dividing the second average particle diameter by the first average particle diameter has an average particle diameter corresponding to 0.17 to 0.26. If it does not have a particle size, it is not possible to contact the first filler and is spaced apart, so that heat dissipation characteristics may be deteriorated, so it is preferable to have the critical significance as described above.

In addition, the third filler fills the space between the first filler and the second filler, and a value obtained by dividing the third average particle diameter by the first average particle diameter has an average particle diameter corresponding to 0.09 to 0.11, If it does not have the same average particle diameter as the above, it is preferable to have the critical significance as described above because the heat dissipation characteristic may be deteriorated due to the separation without contact with the first filler.

In addition, the volume resistance of the first filler, the second filler and the third filler is preferably 10 ⁴ Ωcm or more, and if the volume resistance is less than 10 ⁴ Ωcm, a short circuit occurs when a current is applied to the fire extinguishing sheet. Therefore, it is good to have the critical significance as described above.

In addition, the first filler, the second filler, and the third filler preferably have an average value of the minor axis/long diameter of 0.6 to 0.8. Since heat dissipation characteristics may be deteriorated because

In addition, it is preferable that the percentage of the sum of the masses of the second fillers/the sum of the masses of the first fillers is 11 to 16, or the percentage of the sum of the masses of the third fillers/the sum of the masses of the first fillers is 4.2 to 5.2, and the mass ratio as above If not, the small filler is not added only enough to fill the space formed by the large filler, but a large amount or a small amount is added so that the large fillers are spaced apart and the heat dissipation characteristics may be deteriorated, so it is good to have the above critical significance.

Here, 60 to 80 parts by weight of the filler for heat conduction is added and mixed with respect to 100 parts by weight of the polymer. When it is less than 60 parts by weight, the rate of absorbing the heat transferred to the fire extinguishing sheet becomes slow, and 80 parts by weight When it exceeds, the stirrability with the polymer is greatly reduced, workability is lowered, and the surface finish is lowered, so it is good to have the critical significance as described above.

The flame retardant suppresses combustion of the heat dissipation coating agent due to high temperature heat and thermal conductivity during application and coating on the fire extinguishing sheet, and may include methyl iodide and the like.

Here, 20 to 40 parts by weight of the flame retardant is added and mixed with respect to 100 parts by weight of the polymer, but when it is less than 20 parts by weight, moisture retention, moisture permeability and thermal conductivity are lowered to lower the flame retardant function, and when it exceeds 40 parts by weight, Since a floating shape is generated and moisture permeability is rather reduced, it is good to have the critical significance as described above.

It is good to have the same critical significance.

Strong base is a member that suppresses corrosion by making it easy to remove stains or dust adsorbed on the fire extinguishing sheet when the fire extinguishing sheet is applied and coated when it comes into contact with a brush in the maintenance process. To 5 parts by weight is added, and when it is less than 2 parts by weight, the function of preventing adsorption of dust is lowered, and when it exceeds 5 parts by weight, the possibility of corrosion by adsorption increases by modifying the protein of the adsorbed foreign substances. Therefore, it is good to have the critical significance as described above.

On the other hand, the second coating agent of the present invention, more preferably, 50 parts by weight of any one of alkali metal silicates, 5 parts by weight of phosphoric acid, and 7 parts by weight of a strong base to 100 parts by weight of the inorganic binder, through which, the fire extinguishing sheet By maximizing the prevention of contamination of the fire extinguishing sheet and suppressing corrosion or deterioration caused by foreign substances, the lifespan of the fire extinguishing sheet can be improved.

Therefore, according to the second coating agent, the fire extinguishing sheet can suppress the occurrence of contamination and corrosion due to the adsorption of foreign substances due to external conditions, and even if contamination occurs, it can be easily removed through high-pressure air to improve the lifespan of the fire extinguishing sheet. can

On the other hand, in the heat dissipation coating agent of the present invention, the first coating agent and the second coating agent having the above configuration are mixed in a volume ratio of 2:1 to 4:1, and the mixing volume ratio of the first coating agent and the second coating agent is the If it is out of the range, it is difficult to control the curing time and control the weight average molecular weight after it is applied to the fire extinguishing sheet, and cracks occur due to poor curing, lifting, and deterioration of physical properties. Since the function is also deteriorated, there are problems such as a decrease in heat dissipation performance and a shortened lifespan, it is good to have the critical significance as described above.

On the other hand, the fire extinguishing capsule may be configured in an adhesive state to the lower surface of the fire extinguishing sheet through the second heat dissipation adhesive layer, and may have a known configuration, and may include, for example, a polymer shell and core active fire extinguishing particles.

Here, the polymer shell mixes and dissolves a composition containing a perfluorinated compound, gelatin, and silicon dioxide in a basic solvent, and while heating the mixed solution, the capsule composition is mechanically dispersed in the basic solvent and stirred to obtain a uniform emulsion. It can be obtained by forming the outer wall of the capsule.

In addition, the core active fire extinguishing particles are inserted by applying a technology of inserting gas, liquid and solid into a polymer shell corresponding to a microcapsule of a powder material having a diameter of 3 to 5 micrometers, and hydrofluoric acid prepared from a halogen compound Fires can be extinguished by suppressive cooling using carbon.

Therefore, according to the fire extinguishing sheet, when heat below the critical temperature set for the fire extinguishing function of the fire extinguishing capsule is transferred from the second heat dissipating adhesive layer, a heat dissipation function is provided so that it is released to the outside, and the fire extinguishing capsule is extinguished from the second heat dissipating adhesive layer When heat is transferred in excess of the critical temperature set for the function, the polymer shell ruptures and fire extinguishing function can be provided by the core active fire extinguishing particles.
