Brief introduction to MeiBang new MB-Ionic glass interlayer

MB-Ionic glass interlayer is the interlayer glass ionic polymer interlayer film. The MB-Ionic glass interlayer ionic polymer interlayer film produced by Shanghai Meibang has excellent properties, its tear strength is 5 times as high as that of PVB film, and its hardness is 30-l00 times that of PVB film. At low deformation rate, MB-Ionic glass interlayer laminated glass exhibits elastic-plastic properties, while PVB exhibits super-elastic-plastic properties. At the high deformation rate, PVB hardens and exhibits the properties of elastoplastic,MB-Ionic glass interlayer exhibits a high rigidity in the whole range. MB-Ionic glass interlayer laminated glass has same bending strength as single piece glass on same thickness. Compared with the other interlayer film laminated glass, MB-Ionic glass interlayer laminated glass has higher strength and rigidity, and it can effectively reduce the thickness of glass, especially is beneficial to point-supported glass. MB-Ionic glass interlayer laminated glass has better security performance, can be used in staircase, floor, lighting roof, curtain wall glass, and also can be used to prevent from hurricane, bullet impact, theft etc., thanks to the excellent performance of the strong impact resistance.

建筑幕墙、门窗主要用干法夹层玻璃，符合上述要术有机胶合层材料主要为 PVB 胶片，EVA 胶片用得很少。近年来美邦开发的离子性玻璃中间膜，性能优良，在玻璃采光顶和玻璃外窗、幕墙应用前景广阔、良好。

The building curtain wall, windows and doors are mainly adopted with dry laminated glass. In line with the above requirement, organic laminating layer material are mainly of PVB film and EVA film is rarely used. In recent years, the new developed MB-Ionic glass interlayer has excellent performance in the field of glass lighting roof, glass window and the curtain wall. It has a good broad application prospect.

美邦离子性玻璃中间膜的特性

Characteristics of MB-Ionic glass interlayer

美邦离子性玻璃中间膜是乙烯与甲基丙烯酸酯的共聚物 , 它是一种离子聚合物型中间膜。PVB 膜与玻璃的粘结主要源于聚乙烯醇缩丁醛分子链中酯基与;si—oH 基团中羟基形成的氢键作用。而美邦离子性玻璃中间膜中由于含有1% 左右的金属钠离子,因此膜与玻璃的粘结力主要是离子键作用的结果粘结强度比 PVB 与玻璃间的粘结强度高很多 ( 如果以锤敲试验等级比较,相差 3~4 个级别 )。当然, 美邦离子性玻璃中间膜和PV夹层玻璃都是在140℃、1.2MPa 的高温高压状态下压合而成, 因此,界面分子间经过数十分钟的浸润过程形成的物理吸附也对膜与玻璃的粘结发挥作用。

美邦离子性玻璃中间膜是专门为满足当今建筑业的需要所设计的。它和 PVB具有相同的破碎安全性和碎片保持能力，但能大大地提高安全玻璃的抗冲撞性能，防盗防暴性能及抗灾害性能；要想使玻璃在框架中保持完整，可用更硬，更结实的美邦离子性玻璃中间膜；它适合于天棚玻璃，因其在使用中及破碎后安全性方面有更苛刻的强度和挠度要求。当夹层玻璃温度升高后，它具有更稳定、更长的使用寿命，同时具有优异的耐侯性和边部稳定性。

(MB-Ionic glass interlayer ) is a copolymer of ethylene and methacrylate and it is an ionic polymer intermediate film. The bonding between PVB film and the glass is mainly due to the hydrogen bond between the ester group and the hydroxyl group in the Si-OH group in the polyvinyl butyral molecular chain. However, MB-Ionic glass interlayer contains about 1% sodium metal ions, so the bonding force between the film and glass is mainly the result of ionic bond, and the bond strength is much higher than that PVB (The difference is 3 ~ 4 grades if tested by hammer impact). Certainly, MB-Ionic glass interlayer and PVB laminated glass are all pressed at 140℃,1.2MPa by a high temperature and a high pressure. Therefore, the physical adsorption formed by the infiltration process between the interface molecules will also play a role in the bonding between the film and the glass.

MB-Ionic glass interlayer is designed to meet the needs of todays construction industry. It has the same crushing safety and fragment retention capacity as PVB, but it can greatly improve the anti-impact, anti-theft, anti-riot and anti-disaster perfor-mance of safety glass. To keep the glass intact in the frame, a stiffer and stronger MB-Ionic glass interlayer interlayer film is a better choice. It is suitable for ceiling glass and has more stringent strength and deflection requirements for its safety in use and after breakage. When the temperature of laminated glass increases, it has more stability, longer service life, excellent tolerance and edge stability.
