- the desired heat-shielding performance can be achieved by adding as little ITO fine particles as possible. Preferred to realize.
- the haze of the intermediate film increases in proportion to the blending amount of the ITO fine particles. Therefore, it is desirable to reduce the blending amount of the ITO fine particles in order to keep the haze of the intermediate film small.
- the amount of the ITO fine particles added is 0.4 g / m 2 or more and 0.8 g / m 2 or less. Is preferred. If it is less than 0.4 gZm 2, the heat shielding effect due to infrared shielding may be difficult to obtain, and if it exceeds 0.8 gZm 2 , the price of laminated glass products will increase. Thus, since a desired infrared shielding performance can be obtained with a relatively small amount of ITO fine particles, the price of the laminated glass product and the haze of the intermediate film can be reduced.
- the interlayer film As a method for measuring the amount of ITO fine particles contained in the interlayer film (0.4 gZm 2 or more and 0.8 gZm 2 or less), the interlayer film is cut into approximately 1 cm ⁇ 6 cm, decomposed with acid, and decomposed. Sn and In in the solution were quantified by plasma emission spectrometry.
- An intermediate film containing ITO fine particles of 0.4 g / m 2 or more and 0.8 g / m 2 or less can be produced as follows.
- ITO fine particles dispersed in a plasticizer are kneaded and mixed with PVB resin using a roll mixer.
- the obtained resin material is melted and molded with an extruder to obtain a sheet-like intermediate film.
- Such ITO fine particles may be dispersed in a plasticizer and added to the vinyl resin in order to improve the dispersion in the vinyl resin.
- a plasticizer those generally used for interlayer films can be used, and they may be used alone or in combination of two or more. Specifically, for example, triethylene glycol diol 2-ethyl hexanoate (3GO), triethylene glycol diol 2-ethyl butylate (3GH), dihexyl didipate (DHA), tetraethylene dallicol oxyheptanoate ( 4G7), tetraethylene glycol oxy 2-ethylhexanoate (4GO), triethylene glycol oxyheptanoate (3G7) and the like are preferably used.
- the amount of the plasticizer added is preferably 30 to 60 parts by weight with respect to 100 parts by weight of the bull resin.
- additives may be added to the bull-based resin.
- additives include various pigments, ultraviolet absorbers, light stabilizers, and the like.
- the ultraviolet absorber is not particularly limited, but for example, a benzotriazole type is preferably used.
- the light stabilizer is not particularly limited, but for example, a hindered amine type is preferably used.
- ADK STAB LA-57 manufactured by Asahi Denki Kogyo Co., Ltd. is used.
- a known method is used as a method for forming an interlayer film according to the present invention, and for example, a calender roll method, an extrusion method, a casting method, an inflation method and the like can be used.
- ITO fine particles are added to the bull resin and kneaded to uniformly disperse the particles.
- the vinyl resin composition prepared in this way can be formed into a sheet.
- a heat stabilizer, an antioxidant, etc. are blended as necessary, and an adhesive strength adjusting agent (for example, a metal salt) is added to enhance the sheet penetration. ).
- UV-cut green glass containing iron in order to keep the blending amount of the ITO fine particles small as described above.
- the UV cut green glass for example, the glass composition (mass 0/0, 2. Omm thick equivalent), SiO:
- FeO ratio is 23.5%.
- the UV cut green glass has optical properties (2. Omm thickness conversion), visible light transmittance (YA) 80-86%, solar transmittance (TG) 55-76%, UV transmittance (Tuv) 10 is preferably 25%.
- the conditions for producing such UV-cut green glass are the same as the conditions for producing ordinary float glass. For example, when the prepared glass raw material is melted to about 1500 ° C to obtain a homogeneous glass, it is cast into a float bath, formed, slowly cooled, and cut into a predetermined width.
- composition analysis is performed with fluorescent X-rays, and FeO is a value calculated from the absorbance of glass and the extinction coefficient of FeO.
- the UV-cut green glass containing iron may be at least one of a plurality of glass plates constituting the laminated glass.
- a preferred UV-cut green glass contains 0.66-1.2% Fe 2 O expressed in weight% and converted to Fe 2 O.
- FeO is 15-40% of the total iron. Particularly preferably, it contains 0.7 to 0.88% of all iron converted to Fe O expressed in weight%, and FeO converted to Fe O is 25-30% of all iron.
- the total iron content and the FeO ratio are set in this way.
- the total iron and FeO ratio is small, the solar radiation shielding characteristics deteriorate, and when the total iron and FeO ratio is high, the visible light transmittance decreases.
- the FeO ratio is low, if the total iron is high, the transmitted color becomes yellowish, and if the FeO ratio is high, melting is difficult.
- the thickness of the UV cut green glass is preferably in the range of 1.4 mm-2.5 mm. This is because if the thickness is less than 1.4 mm, the glass strength is lowered, and the perspective distortion of the glass base plate is not good. On the other hand, if it exceeds 2.5 mm, the visible light transmittance decreases, and the necessary visible light transmittance cannot be secured. More preferably, as the laminated glass, the visible light transmittance must be 70% or more. Therefore, the total thickness of the glass plates constituting the laminated glass should not exceed a maximum of 4.3 mm. The thickness of the plate should be determined as appropriate. An example of the glass plate thickness dimension is a combination of 2.5 mm and 1.8 mm.
- a plasticizer (3GH: triethylene glycol-ethyl propyl propylate) containing 0.21% by weight of ITO fine particles is added to 100 parts by weight of PVB resin and added to the roll mixer together with other UV absorbers. And kneaded and mixed at about 80 ° C for 30 minutes. The resin raw material thus obtained was melted at about 200 ° C. and formed into a film having a thickness of 0.76 mm by an extruder.
- a 50 mm opening was cut from the intermediate film obtained in Step 1, dissolved in an appropriate solvent, and quantitative analysis of In and Sn was performed by ICP, and as a result, the content of ITO fine particles was measured. More specifically, the cut interlayer film was decomposed with acid, and Sn and In in the decomposed solution were quantified by plasma emission analysis.
- Example 2 was obtained by changing the amount of ITO to 0.5 gZm 2 in Example 1.
- a plasticizer (3GH: triethylene glycol-ethyl butyrate) containing 0.15% by weight of ITO fine particles is added to 100 parts by weight of PVB resin. It was added and kneaded for 30 minutes at about 80 ° C with a roll mixer together with other UV absorbers. The raw material for the obtained resin was melted at about 200 ° C. and formed into a film having a thickness of 0.76 mm by an extruder. Step 2 and subsequent steps are the same as in Example 1.
- Example 2 As a comparative example, the laminated glass of the comparative example under the same conditions as in Example 1 except that the ITO fine particles contained in the plasticizer are 0.36% by weight and the glass is green glass manufactured by Nippon Sheet Glass Co., Ltd. And measured.
- the measurement results of Examples and Comparative Examples are shown in Table 1, and the spectral transmittance is shown in FIG.
- the haze of laminated glass is 0.4% or less, and the transmittance at 1500 nm. Can be reduced to 20% or less, and the visible light transmittance to the standard light source A can be increased to 70% or more. Therefore, the laminated glass of the present invention can increase the visible light transmittance, reduce the solar transmittance and the 1500 nm transmittance, and reduce the size / J by using the ITO fine particles having a small dispersion blending ratio.
- the three-layer sound insulation interlayer is known to have a three-layer structure of PVB resin layer Z sound insulation layer Z PVB resin layer, but one side or both sides of such a three-layer intermediate film are known. It dispersed 0. 8GZm 2 following ITO fine particles in total on the PVB ⁇ obtain an intermediate film having a three-layer structure, that this obtain a laminated glass was sandwiched by two sheets of UV cut green glass as described above it can.
