Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
Referring to fig. 1 to 3, the main components of the safety mirror of the present application are a peripheral support frame 1, an adhesive layer 2, and a
The peripheral supporting frame 1 only needs to be a peripheral frame and a hollow structure in the middle. In the embodiment, the peripheral supporting frame 1 cuts an aluminum alloy section (or other sections) into 4 sections with 2 lengths and 2 widths according to the required size requirement, bevels the two ends of each section of the aluminum alloy section by 45 degrees, and then assembles the 4 sections of the aluminum alloy section to obtain an aluminum alloy frame finished product.
Of course, the peripheral support frame 1 is not limited to the structure given in the present embodiment, and may have other structures such as a triangle, a polygon, a circle, and the like. The beveling of the end portions of two adjacent edges of the peripheral support frame 1 by an angle of 45 ° enables the frame to be more flat and attractive. When the length or width of the side length of the peripheral supporting frame 1 is greater than 50CM, a supporting rod/surface can be added at the middle position of the peripheral supporting frame 1 for fixing, so as to enhance the overall firmness and flatness of the peripheral supporting frame 1.
The PC film is an amorphous, odorless, nontoxic and highly transparent colorless or yellowish thermoplastic engineering plastic, has excellent physical and mechanical properties, particularly excellent impact resistance, high tensile strength, bending strength and compressive strength, good heat resistance and low temperature resistance, stable mechanical property, dimensional stability, electrical property and flame retardance in a wider temperature range, can be used for a long time at minus 60-120 ℃, is in a molten state at 220-230 ℃, and has no obvious melting point.
In the present application, the optimal thickness of the transparent PC film substrate 31 is selected to be 0.25-1.50 mm. The finished PC mirror film mirror surface is not easy to bend and wrinkle, the light reflectivity of the mirror surface is higher, and the imaging effect is better.
After the transparent PC film base layer 31 is vacuum plated with aluminum, it needs to be stretched to make the mirror surface flat and the light reflectivity better. The tensile force of the stretching is controlled to be 10-20N. The periphery of the
The synthetic transparent resin layer is arranged on the front surface of the PC film base layer 31, and the synthetic transparent resin layer forms a protective layer on the front surface of the PC film base layer 31 after being cured, so that the mirror film has the performances of scratch resistance and friction resistance, and the light reflection effect of the mirror surface cannot be reduced due to daily wiping.
The invention changes the traditional mirror mode which takes glass as material, adopts the vacuum plating aluminized PC film with high light reflectivity as the mirror surface, and has the weight of the peripheral supporting frame only, and the weight of the vacuum plating aluminized PC film is light and almost negligible, so the weight is greatly reduced and is about 15 percent of that of the common glass mirror with the same area.
