Description

technical field [0001] The invention relates to the technical field of anti-glare films, in particular to an anti-glare film with high wear resistance and low flash point and a preparation method thereof. Background technique [0002] With the rapid development of the electronic information industry, various portable electronic terminals and electronic products, such as mobile phones, computers, conference electronic tablets, etc., have become extremely popular, bringing great convenience to people's work and life. But in the process of actually using electronic products, people are often affected by "glare". "Glare" refers to the visual condition that causes visual discomfort and reduces the visibility of objects due to unsuitable brightness distribution or extreme brightness contrast in space or time in the field of vision. Strong glare can also cause problems such as vision loss, depression, and irritability. "Anti-glare" means that when light passes through the screen ...
