Method for sticking three-dimensional (3D) glass with decorative film assembly, and 3D laminated glass

Abstract

The invention discloses a method for sticking three-dimensional (3D) glass with a decorative film assembly, and the 3D glass. The method for sticking the 3D glass with the decorative film assembly comprises the following steps: heating and pressurizing the decorative film assembly, wherein the heating temperature is 90-110 DEG C, the pressurizing pressure is 0.4-0.6MPa, and the time is 50-70S; positioning the heated and pressurized decorative film assembly and the 3D glass to form a positioned intermediate; transferring the positioned intermediate onto a silica gel mould for shaping so as to form a shaped intermediate; tearing off release film on the shaped intermediate to form a film-free intermediate; sticking the film-free intermediate under the vacuum condition to form a stuck intermediate; defoaming the stuck intermediate under the condition of high pressure to obtain the 3D laminated glass. The method for sticking the 3D glass with the decorative film assembly is high in yield and low in cost.

Description

technical field [0001] The invention relates to a bonding method of 3D glass and a decorative film component and 3D bonding glass. Background technique [0002] The application of 3D glass on the cover of mobile phones has become the first choice of many brand mobile phone manufacturers. The application of 3D glass on the front cover of mobile phones replaces the original 2D and 2.5D covers, and the appearance is more novel and beautiful. 3D glass is applied to the back cover of the mobile phone instead of the metal cover, which also has the advantage of enhancing the receiving function. But at present, during the UV film setting process of 3D glass, the four-sided curved product is prone to wrinkles, resulting in low product yield, and the product shape design is greatly restricted. In the process of bonding, the UV film only plays the role of tensioning and setting, but its material cost accounts for 20% of the total cost, so it also causes high cost. Contents of the in...
