The present invention relates to the technical field of glass. Disclosed is a composite strengthening method for improving the strength of ultrathin glass. The method specifically comprises: the following composite strengthening steps for an ultrathin glass cover plate: step 1. cleaning and drying the surfaces of an ultrathin glass cover plate prepared on a production line; and step 2. using ultrafast laser to perform full-surface heat accumulation treatment on the front and back surfaces of ultrathin glass, and naturally cooling the ultrathin glass to microcrystallize the upper and lower surfaces of the glass. By using these steps to strengthen the ultrathin glass cover plate and using laser to induce microcrystallization on the surfaces of the glass before chemical strengthening, the present invention solves inherent deformation and warpage problems caused by conventional physical tempering, and problems such as insufficient strength of the ultrathin glass caused by insufficient degree of ion exchange in single chemical strengthening, ensuring not only the appearance of the ultrathin glass but also the strength and bending performance of the glass.

This invention provides a high-strength, stable engineering stress-distribution glass, its preparation method, and apparatus. One side of a glass sample that has undergone a single ion exchange is cooled to a low temperature, while the other side is brought into contact with the molten salt surface. The ion exchange temperature cutoff depth inside the glass is determined by the molten salt temperature. A second ion exchange is then performed to obtain the high-strength, stable engineering stress-distribution glass. This invention simplifies and controls the secondary ion exchange process for glass, achieving both increased glass strength and improved glass stability.
