Problems solved by technology

One is to use the coating method to make anti-infrared lenses. The method of coating the coating is complicated, the production is troublesome, and the cost is high. Moreover, the color of the coated coating is unstable and uneven. After a period of use, the coating still exists. The situation of damage or even peeling will lead to the loss of anti-infrared function and poor product quality
The other is to use ordinary masterbatches to add injection molding to make anti-infrared lenses. During the mixed injection molding process of these ordinary masterbatches with PC / PA plastic rice, it is easy to cause carbonization because they are not resistant to high temperatures, making black spots and impurity spots appear on the lenses. , which directly affects product quality

Embodiment 20

[0071] Example 20 is to use the masterbatch of Example 10 in Table 1 and the PC material to mix and stir at a ratio of 1:4, and inject molding. As shown in Table 6 and Figure 4 , the results show that the infrared transmittance (780nm-2000nm) is 6.38%, the visible light transmittance is 76.96%, the haze is 2%, the surface quality is good, there are no black spots and impurities, and it has passed the American standard, European standard and Australian standard. Compared with the best example 18, the anti-infrared effect of example 20 is better, but the haze value is relatively higher, and the visible light transmittance is also lower.

Embodiment 18

[0089] Example 18 After the lens is irradiated by infrared rays, the temperature difference between the environment below the lens and the lens above is the smallest, and the heat insulation effect is the best.

Abstract

The invention discloses a manufacturing method of an anti-infrared high-energy heat-insulation goggles lens. The manufacturing method comprises the following steps: firstly, drying PC or PA; uniformly mixing 8-15 kg of PC or PA with 8-13 g of nano-scale metal oxide and 2-7 g of a dispersing agent; forming a strip-shaped material from the mixed material; forming a cylindrical anti-infrared master batch from the strip-shaped material; drying PC or PA plastic grains; matching the prepared anti-infrared master batch and dried PC or PA plastic grains according to the proportion that 0.1-0.5 kg of master batch corresponds to 1 kg of plastic grains, and uniformly stirring; and forming the anti-infrared high-energy heat-insulation goggle lens from the stirred mixed material. According to the invention, the manufacturing method is simple, the cost is lower, the color is more stable and uniform, and the product quality is improved; and detection results show that the light transmittance of a 780-2000 nm infrared region reaches 8.69%, namely, the blocking rate is 91.31%, the visible light perspective rate reaches 78.43%, the haze reaches 0.8%, and the product has the advantages of preventing near infrared rays from irradiating eyes, insulating heat, protecting the skin around the eyes, slowing down aging and reducing the occurrence probability of cataract.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of sun lenses, in particular to a method for manufacturing an anti-infrared high-energy heat-insulating goggle lens. Background technique [0002] Light is divided into wavelengths, including ultraviolet, visible light and infrared. Visible light (red, orange, yellow, green, blue, blue, and purple) refers to the light that people can perceive visually, ultraviolet light is light outside the purple light in the spectrum, and infrared light is light outside the red light in the spectrum. Infrared rays are a kind of thermal radiation with strong penetrating power. They can directly reach the fundus and be absorbed by the retina, causing acute eye damage, and long-term exposure even induces cataracts. Therefore, under special circumstances, it is necessary to wear eye protection to prevent damage to the eyes by infrared rays, and glasses products with anti-infrared functions have a...
