Abstract

The invention provides a polyvinyl butyral resin based laser protective coating and a preparation method thereof, wherein the substrate of the coating is the polyvinyl butyral resin and filler is (Sn<1-x-y>SbxEry)O2, 0.1 <= x <= 0.2 and 0.01 <= y <= 0.02. Mass ratio of the filler to the substrate is 1.5-2. The coating has difunctional effect of absorption and up-conversion on infrared laser of 1.06 [mu]m and 1.54 [mu]m and shows strong absorption effect on infrared laser of 10.6 [mu]m, thus achieving the object of laser protection. The coating can bear temperature change from -40 DEG C to 350DEG C, wherein diffuse reflectivity is maintained to be lower than 0.5%; the coating allows room temperature curing, is low and uniform in thickness, has good surface status, is not less than 1-gradein adhesive force and is not less than 50 kg / cm in anti-impact strength. The coating can be applied to the field of laser protection as a high- and low-temperature resistant coating.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a polyvinyl butyral resin-based laser protective coating and a preparation method thereof. Background technique [0002] Laser has been widely used in industry, commerce, scientific research, medical treatment and military due to its characteristics of high brightness, good directionality, low interference and wide frequency band. However, due to the high energy density and concentrated energy of the laser, it may cause great damage to the irradiated parts of the human body. With the continuous improvement of laser energy, the continuous increase of laser varieties and the continuous expansion of laser application range, laser damage to personnel vision and equipment is becoming more and more serious, especially infrared lasers such as 1.06 μm, 1.54 μm and 10.6 μm. Damage protection research also needs to be carried out simultaneously. Due to the high energy of the laser, irradiat...
