Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0024] figure 1 It is a structural schematic diagram of an explosion-proof lamp in the present invention, figure 2 yes figure 1 A partial enlargement of the . like figure 1 and figure 2 As shown, the explosion-proof lamp of the present invention includes a housing 101 on which a cable access hole 102 is arranged. The cable access hole 102 includes two parts with different diameters: a large diameter part 105 and a small diameter part 106, thereby forming a stepped surface 104 therebetween. The cable 103 enters the small-diameter part 106 after passing through the large-diameter part 105 , a...

Abstract
The invention relates to a sealing stuffing and preparation method thereof, as well as explosion-proof light with fire-retardant property. The explosion-proof light comprises a shell, wherein the shell is provided with a cable inlet / outlet hole. The cable inlet / outlet is provided therein with the sealing stuffing of a hollow circular cylinder shape. The sealing stuffing is composed of (by weight percentage) 80.5-89.5 neoprene, 3-5 flame retardant synergist, 2-3 lower extraction plasticizer, 2-3 curing agent , 1-2 accelerator, 1-1.5 anti-aging agent, 0.5-1 reinforcing agent, and 2-4 color agent. The inventive sealing stuffing uses a unique formula, and has excellent flame retardant properties, and relatively stable anti-aging performance. The explosion proof light still has a good protection level and fireproof performance even after it is used for a long time while maintaining good sealing performance.
Description
technical field [0001] The invention relates to a lamp, more specifically to a sealing stuffing box, a preparation method thereof, and an explosion-proof lamp with flame-retardant performance. Background technique [0002] When the cable is led into or out of the lamp, a sealing stuffing box is usually installed in the cable access hole of the explosion-proof lamp housing for sealing. The sealing stuffing box is mostly made of rubber, and it is directly in close contact with the shell. However, light fixtures often dissipate significant amounts of heat through their housings. The heat generated by the light source in the lamp and related electrical components is transferred to the lamp housing through heat conduction, so that the temperature of the housing rises significantly. This will keep the stuffing box at high temperature for a long time. However, the sealing stuffing boxes used for lamps currently on the market do not have flame-retardant properties, and there are ...
