preparation example Construction

[0032] The preparation method of the transparent plate sheet is:

[0033] (1) According to the formula ratio, add the raw materials into the kneader and mix evenly, and knead at a temperature of 95-120°C for 8-20 minutes;

[0034] (2) Then discharge the kneaded mixture, stir and cool to 35-40°C;

[0035] (3) adding the material into the granulator for twin-screw extrusion and granulation, the temperature of the screw extruder is 120-180°C;

[0036] (4) Then add the extruder to extrude the sheet. The barrel temperature of the extruder is 150-190°C, and then enter the pressure roller to extrude the material. The temperature of the pressure roller is controlled at 50-80°C. Cool and form to obtain a sheet of a light-transmitting plate.

[0037] The end surface 3 is a semi-arc convex surface, and the light-transmitting plate 2 is provided with a semi-arc concave surface matched with the semi-arc convex surface.

[0038] The outer surface is provided with an annular stepped surfa...

Embodiment 1

[0042] Light-transmitting plate material composition: 100 parts of polyvinyl chloride resin (YH-2500 polyvinyl chloride resin: S-700 polyvinyl chloride resin = 8:1), 2 parts of stabilizer (CZ-001 stabilizer), lubricant (GH -104) 0.5 parts, coloring agent (ultramarine powder) 0.001 parts, impact modifier (MBS) 3 parts, dioctyl phthalate 3 parts.

[0043] The preparation method of the above-mentioned light-transmitting plate sheet of the present invention is:

[0044] 1 According to the proportion of the formula, add the raw materials into the kneader and mix evenly, and knead for 8-20min at a temperature of 95-120°C;

[0045]2 Then discharge the kneaded mixture, stir and cool to 35-40°C;

[0046] 3. Put the material into the granulator for twin-screw extrusion and granulation. The temperature of the screw extruder is 120-180°C;

[0047] 4 Then add the extruder to extrude the sheet. The barrel temperature of the extruder is 150-190°C, and then enter the pressure roller to extr...

Abstract

The invention discloses an LED lamp used for a distribution box. When a transparent board is struck, the transparent board has a buffering effect, so that the probability of damage to the transparent board is reduced, and no gap is formed when a lamp body is connected with the transparent board. The LED lamp comprises the lamp body (1) and further comprises the elastic transparent board (2), wherein the outer annular side face of the end of the lamp body (1) is covered with the inner annular side face of the transparent board (2), and the end face (3) of the end of the lamp body (1) is attached to the inner bottom surface of the transparent board (2). The transparent board (2) is composed of, by weight, 100 parts of pvc resins, 2-3 parts of stabilizing agents, 0.5-1 part of a lubricating agent, 0.001-0.0015 part of a coloring agent, 1-4 parts of impact modifiers and 2-5 parts of dioctyl phthalate.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp for a distribution box. Background technique [0002] Lighting is required in the distribution box, and LED lights are a better choice, such as "a distribution box for automatic lighting" with the publication number CN 103500943 A, but the connection between the lamp body of the LED light and the light-transmitting board is basically It is a tight connection. When workers operate in the distribution box, it often happens that the light-transmitting board is accidentally hit by a human body or a tool. Not only is the light-transmitting board easily damaged, but also the connection between the lamp body and the light-transmitting board will vibrate. , There will be a gap at the joint between the lamp body and the light-transmitting plate, thereby destroying the seal between the lamp body and the light-transmitting plate. The above situation makes the service life of t...
