Problems solved by technology

At the same time, since the driving information is projected onto the front windshield, the displayed background is the external environment. Due to changes in temperature, it is very easy to fog. At present, air conditioning, electric heating, etc. can be used to prevent fog, but this method must rely on the outside world. Conditions, currently there is no HUD film with anti-fog effect

Abstract

The invention provides a preparation method of an anti-fog HUD (Head Up Display) film. The preparation method comprises the following steps: primarily cleaning a polycarbonate substrate; performing plasma treatment; opening a radio frequency ion source to start film formation, namely (1) depositing a Ti3O5 film and (2) depositing a SiO2 film; uniformly spin-coating the prepared interlayer sol on the surface of the polished clean glass substrate, curing, taking out and cooling to room temperature to obtain an interlayer film; spin-coating the prepared anti-fogging layer sol on the surface coated with the middle layer film, and curing to obtain an anti-fogging layer film; and cooling to room temperature to obtain the anti-fog HUD film. The invention provides the preparation method of the anti-fog HUD film aiming at the condition that most of current HUD films do not have an anti-fog function, and the prepared HUD film has the advantages of excellent basic performances (salt fog resistance, cold and hot impact resistance, low temperature resistance, high temperature resistance, ultraviolet aging resistance and friction resistance) and good anti-fog performance, and does not change after being subjected to a steam exposure resistance test at 80 DEG C for 80 hours.

Description

technical field [0001] The invention relates to the field of head-up display film materials, in particular to a preparation method of an anti-fog HUD film. Background technique [0002] The HUD (head up display) head-up display was first used as an auxiliary instrument on the aircraft. Through the centralized transmission of parameters, the driver can grasp most of the driving information of the vehicle without looking down at the instrument. At present, this technology is also used by The introduction of automobiles has been relatively slow in the past period of time, but overcoming obstacles such as cost and scale, HUD has returned to people's field of vision. With the emergence of AR technology, the advantages of HUD are becoming more and more obvious. The working principle of the HUD is projection - projecting the road information of the car to the front of the driver, so that there is no need to look down at the instrument panel frequently, which improves the safety and...
