Abstract
The utility model discloses an anti-dazzle plate, belonging to the technical field of material engineering. The anti-dazzle plate comprises a transparent substrate, and also comprises a connecting layer covering the transparent substrate and a scattering layer covering the connecting layer. The connecting layer is made of silicon dioxide. The scattering layer is a composite coating made of silicon dioxide and zinc oxide. The anti-dazzle plate uses nanometer silicon dioxide as the connecting layer, and has excellent high temperature resistance and adhesion of the scattering layer is reinforced. Zinc oxide particles and silicon dioxide added in the scattering layer have different refractive indexes, enabling the light to be dispersed uniformly in the scattering layer and reaching soft light effect, hence anti-dazzle effect is increased. Meanwhile, the zinc oxide particles are transparent, therefore light scattering effect is increased and higher light passing rate is ensured.

Fig. 2 is the track schematic diagram of the light that provides of the utility model embodiment in scattering layer.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
Referring to Fig. 1, the utility model embodiment provides a kind of anti-dazzle tabula rasa, anti-dazzle tabula rasa comprises transparency carrier 1, anti-dazzle tabula rasa also comprises the articulamentum 2 covering on transparency carrier 1 and covers the scattering layer 3 on articulamentum 2, articulamentum 2 is silicon dioxide layer, and scattering layer 3 is silicon dioxide and zinc paste composite coating.Silicon dioxide (SiO
2) there is extremely strong uv absorption and infrared external reflection characteristic, make articulamentum 2 and scattering layer 3 there is excellent heat-proof quality, improved the resistance to elevated temperatures of anti-dazzle tabula rasa; While SiO
2articulamentum 2 has also been strengthened the adhesion of scattering layer 3.Scattering layer 3 mainly plays homogenize and transmitted ray.
Further, silicon dioxide and zinc paste composite coating comprise silicon dioxide layer and are dispersed in the Zinc oxide particles (ZnO) 4 in silicon dioxide layer.Preferably, the size diameter of Zinc oxide particles 4 is 15-150 nanometer.SiO
2refractive index be 1.45-1.55, the refractive index of ZnO is 1.9-2.0, during light incident ZnO particle, can when incident and outgoing, reflect respectively, and emergent ray can deflect with respect to incident ray; Make like this light in the interior meeting of scattering layer 3 through repeatedly such light refraction, then disperse uniformly, make pointolite become area source, the light soft effect that reaches anti-dazzle that becomes.ZnO particle is transparent material simultaneously, so can also guarantee high light percent of pass when increasing scattering of light.
As shown in Figure 2, be the track schematic diagram of light in scattering layer in the anti-dazzle tabula rasa of the utility model embodiment.In figure, the direction of arrow is the direction of light incident in scattering layer, refraction, outgoing ZnO particle.Wherein, incident angle when α angle is light process ZnO particle, β angle is emergence angle, deflection angle is 2 (alpha-betas).Due to the refractive index of scattering layer 3 refractive index higher than articulamentum 2 and air, so more easily there is total reflection at two interfaces of scattering layer 3 in light, thereby increase reflection and the refraction number of times of light in scattering layer 3, further strengthened the homogenising that luminous energy angulation distributes, thereby raising mist degree, has reached the object of anti-dazzle from visual angle.
