Abstract

The invention provides an organic silicon resin-based laser protection coating and a preparation method. A substrate of the coating is provided with high-temperature-resistant self-dry organic siliconresin, a filler of the coating is (Sm1-x-yErxMny) BO3, wherein 0.005<=x<=0.02, and 0.1<=y<=0.2. The weight ratio of the filler to the substrate is 0.75-1. The coating has absorption and up-conversioneffects on 1.06-micrometer and 1.5-micrometer infrared lasers and absorption effects on 10.6-micrometer infrared lasers, and laser protection can be achieved. The coating can bear temperature changewithin the range of 40 DEG C below zero and 350 DEG C, the diffuse reflectance of the coating is kept by 1% or less, and the coating can be cured at the room temperature and has the advantages that thickness is thin and uniform, surface states are good, adhesive force is larger than or equal to 1, impact-resistant strength is larger than or equal to 50kg*cm. The coating can simultaneously serve asa high-temperature-resistant and low-temperature-resistant coat to be used for the field of laser protection.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an organic silicon resin-based laser protective coating and a preparation method. 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, irradiation on th...
