Abstract
The application discloses a kind of interlayer laminated glass and preparation method thereof, it is related to the technical field of special glass.A kind of interlayer laminated glass, including first glass, second glass and interlayer, wherein the interlayer is by modified PVB adhesive film and aliphatic TPU adhesive film sequentially laminated and laid and is composed, and the outermost layer of interlayer both sides is modified PVB adhesive film, and modified PVB adhesive film is made of PVB resin, modified silica gel powder, polyvinylpyrrolidone, composite plasticizer, weathering aid and silane coupling agent.By the present application scheme, not only can effectively reduce the initial yellow index of interlayer laminated glass, but also can greatly improve the cohesive strength and bonding strength of interlayer under the premise of only sacrificing a small amount of light transmittance, while improving the ultraviolet resistance and water resistance of interlayer, to effectively solve the problems such as traditional PVB interlayer laminated glass yellowing, insufficient light transmittance, poor ultraviolet resistance and water resistance.
