Anti-glare particle composition, coating, plate and preparation method thereof

The invention relates to the field of materials, in particular to an anti-glare particle composition, a coating, a plate and a preparation method of the anti-glare particle composition. Specifically, the anti-glare particle composition comprises the following components in parts by mass: 40-70 parts of polymethyl methacrylate particles with the particle size of 1-5 microns and 10-20 parts of silicon dioxide particles with the particle size of 1.5-5 microns. The proportion of the anti-glare particles with different density gradients in the composition is adjusted, and the particle size of the anti-glare particles is controlled within a certain range, so that the particle distribution condition in the curtain coating process is controlled, uniform curtain coating of substrates such as plates is realized, the haze difference caused by uneven distribution of anti-glare particles due to gravity at the upper end and the lower end is reduced, and the uniform haze distribution effect is achieved. The anti-glare parti
