防尘材料及其制备方法、激光投影设备
摘要：
本发明公开了一种防尘材料及其制备方法、激光投影设备，属于散热技术领域。该防尘材料包括：用于与基底接触的底涂层以及形成于所述底涂层上的防尘涂层；所述底涂层由以(甲基)丙烯酸和/或(甲基)丙烯酸酯为单体聚合得到的丙烯酸酯胶黏剂形成；所述防尘涂层由防尘涂料形成，所述防尘涂料包括以下重量份数的组分：100重量份的含氟丙烯酸酯树脂和0.5～2重量份的平均粒径为2μm以下的聚四氟乙烯微球。该防尘材料能够有效防止灰尘积聚，从而克服由于灰尘积聚而导致的散热性能差的问题，并且该防尘材料还具有良好的与基底的结合能力以及良好的耐热性能。
摘要（英）：

The invention discloses a dustproof material, a preparation method thereof and laser projection equipment, and belongs to the technical field of heat dissipation. The dustproof material comprises a priming coating layer in contact with a substrate and a dustproof coating layer formed on the priming coating layer, wherein the priming coating layer is formed by an acrylate adhesive obtained by polymerizing (meth) acrylic acid and/or (meth) acrylate as monomers; the dustproof coating layer is formed by dustproof coating; the dustproof coating comprises the following components in parts by weight: 100 parts of fluorinated acrylate resin and 0.5-2 parts of polytetrafluoroethylene microspheres with the average particle diameter being smaller than 2 microns. The dustproof material can effectively prevent dust accumulation, so that the problem of poor heat dissipation caused by the dust accumulation is solved; the dustproof material also has good substrate bonding capability and good heat resistance.
