AI Technical Summary
The surface of existing automobile glass is smooth, resulting in a long retention time of water droplets, affecting the efficiency of rainwater flow.
Add another pressing process before the glass tempering process, and press small columns covered with matrix on the smooth surface of the glossy glass to form a diamond, square or circular cylinder matrix with a spacing between 0.5MM and 2MM.
Through the small cylinder structure, raindrops are easier to spread on the glass, forming a water film quickly, and water droplets quickly fuse when they fall into contact. The water film is thin and transparent, without affecting the transparency of the glass, significantly improving the water droplet retention time.

Abstract
Description
[0001] Technical field: The present invention relates to the technical field of automobile glass products, and in particular to a new type of automobile glass with improved water droplet retention time.
[0002] Background technology: Nowadays, automobile glass is all made of smooth glass, and water droplets stay for a long time. In nature, the size of raindrops is usually between 0.5 mm and 6 mm. When raindrops fall on the smooth glass, they form large and small water droplets due to the effect of surface tension. When the water droplets are small, the surface tension dominates, making the water droplets remain spherical or approximately spherical. Raindrops continue to fall from the sky, or water droplets merge with water droplets. When the water droplets gradually grow on the glass, their own gravity begins to dominate until the balance between the surface tension and gravity of the water droplets is broken, causing the water droplets to begin to flow.
[0003] Invention content: The technical problem to be solved by the present invention is to provide a glass having a smooth surface on the side inside the car cab and a changed surface structure on the side outside the car cab. An additional pressing process is added before the glass tempering process to press out a matrix of small columns on the smooth glass surface with small intervals, so that a water film is easily formed when it rains, thereby improving the retention time of water droplets.
[0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: before the glass tempering process, an additional pressing process is added, and a matrix of small columns is pressed out on the smooth glass surface. Of course, it is determined whether the matrix small columns are pressed out on the entire glass or partially according to the needs. When raindrops fall on the glass surface treated with the matrix small columns, the small columns make it easier for the raindrops to spread on the glass and quickly form a water film. Since the main component of glass is silicon dioxide (SiO2), this material has a strong hydrophilicity. A water circle is adsorbed around each small column. The shape of the small column is usually made into a diamond column, a square column, or a round column. The spacing of the small column matrix is between 0.5MM and 2MM. As the raindrops continue to increase, a thin water film is quickly formed where the glass has a small column matrix. This water film enables the raindrops to quickly merge when they fall and touch. The water droplets will spread on the surface and be quickly absorbed, and flow to the lower part of the slope in the form of a water film. Because the top of the small column is flat and smooth and the small column is short, the water film is very thin and will not affect the transparency of the glass. Description of the drawings:

Claims
1. A new type of automobile glass with improved water drop retention time, characterized in that: The glass surface is covered or partially covered with small columns, which are usually in the shape of diamond columns, square columns, or round columns. The glass surface is characterized in that the glass is composed of a matrix of small columns, which are usually in the shape of diamond columns, square columns, or round columns.
2. A novel automobile glass with improved water drop retention time according to claim 1, characterized in that: The glass surface is covered with or partially covered with a matrix of small columns. When raindrops hit the glass whose surface is covered with or partially covered with a matrix of diamond columns, square columns, or circular columns, the raindrops will spread more easily on the glass. Because a water circle is adsorbed on the roots of the diamond columns, square columns, or circular columns, and the distance between each column is small, a large thin water film is quickly formed on the glass surface. This layer of water film allows the raindrops to quickly merge and be absorbed when they fall and touch the glass.
