Definitions
- Embodiments of the present application relate to an olefin resin for an optoelectronic device encapsulant, a resin composition comprising the same, an encapsulant film, a method for producing the optoelectronic device encapsulant, and an optoelectronic device.
- Optoelectronic devices such as photovoltaic cells, light emitting diodes (LEDs), or organic LEDs, are encapsulating materials that encapsulate the light emitting or photosensitive sites of the device ( Encapsulant).
- a lamination method in which a transparent front substrate, an encapsulant, a photovoltaic element, an encapsulant, and a back sheet, which are typically light-receiving substrates, are laminated, and then heat-compressed while vacuum-stacking the laminate. It can be prepared by.
- Embodiments of the present application provide an olefin resin for optoelectronic device encapsulant having a novel physical property, a resin composition comprising the same, an encapsulant film, a method for producing the optoelectronic device encapsulant and an optoelectronic device.
- One embodiment of the present application provides a polyolefin resin having two crystallization temperatures (Tc).
- the polyolefin resin having the two crystallization temperatures may have excellent light transmittance, and may be applied to various photovoltaic devices that require excellent light transmittance, for example, an encapsulant for encapsulating a device of a solar cell. .
- olefin resin means a resin including a polymer or copolymer derived from an olefinic monomer, and does not include a resin blend.
- polymer derived from a monomer means a derivative of a monomer, for example, a polymer including the polymerized unit of the monomer.
- crystallization temperature means the temperature at which crystallization occurs in which the irregular structure of the structure changes regularly due to molecular / atomic attraction, and for example, differential scanning calorimetry (Differential Scanning Calorimetry, DSC).
- the crystallization temperature is about 0.5 mg to 10 mg of the sample in the measuring vessel, the nitrogen gas flow rate to 20 ml / min, in order to equalize the thermal history of the polyolefin resin, 20 ° C / min After heating up from 0 degreeC to 200 degreeC at a temperature increase rate, it is hold
- peak means a vertex or a vertex of the cooling curve or the heating curve to be described later, and for example, indicates a point where the slope of the tangent line is zero.
- the point where the sign value of the slope of the tangent line does not change that is, the inflection point, is excluded based on the point where the tangent slope is 0 among the points where the tangent line has a zero slope.
- the polyolefin resin according to one embodiment of the present application has two crystallization temperatures, for example, a first crystallization temperature of 20 ° C to 35 ° C and a second crystallization temperature higher than the first crystallization temperature.
- the polyolefin resin the cooling curve peak of the heat flow measured by DSC while cooling at a rate of 10 °C / min from 200 °C to -150 °C temperature 20 °C to 35 °C and 35 °C to 75 °C
- the peaks appearing at 20 ° C. to 35 ° C. are the first crystallization temperature
- the peaks appearing at 35 ° C. to 75 ° C. are the second crystallization temperature.
- the first crystallization temperature of the polyolefin resin may be 24 °C to 33 °C
- the second crystallization temperature may be 40 °C to 70 °C.
- the difference between the first crystallization temperature and the second crystallization temperature may be 10 ° C or more, for example, 15 ° C or more. If the difference between the first crystallization temperature and the second crystallization temperature is too small, the light transmittance of the polyolefin resin may decrease, and the upper limit of the difference between the first crystallization temperature and the second crystallization temperature is not particularly limited. For example, it may be 50 °C.
- the polyolefin resin of the present application the density is 0.850 g / cm 3 to 0.880 g / cm 3 , for example, 0.855 g / cm 3 to 0.870 g / cm 3 , 0.859 g / cm 3 to 0.880 g / cm 3 Or 0.855 g / cm 3 to 0.877 g / cm 3 .
- the density of the polyolefin resin can be adjusted within the above range.
- the crystallization temperature as the density of the polyolefin resin increases, the polyolefin resin may have a high crystallization temperature.
- the first crystallization temperature of the polyolefin resin is 23 °C to 28 °C
- the second crystallization temperature is from 40 °C to Respectively, or when the density of the polyolefin resin is about 0.875 g / cm 3 to 0.880 g / cm 3 , the first crystallization temperature of the polyolefin resin is 30 ° C. to 35 ° C .
- the two crystallization temperatures may be present at temperatures of 50 ° C. to 67 ° C. respectively.
- the “melting temperature” is a temperature at which the polymer resin changes from a solid state to a liquid state having fluidity, and means a temperature at which the flow of the crystal part of the resin starts, and can be analyzed through the above-described DSC.
