Embodiment 1

[0077] Embodiment 1: In this embodiment, the high thermal conductivity nanometer rapid vulcanization composite EPDM rubber, the content ratio of each raw material component is as follows in parts by weight:

[0078] EPDM rubber 150-200 parts,

[0079] Anti-aging agent 1-4 parts,

[0080] 40-80 parts of carbon black,

[0081] 1-3 parts of sulfur,

[0082] Accelerator 1-3 parts,

[0083] 6-10 parts of plasticizer,

[0084] 40-80 parts of paraffin oil,

[0085] Organic active agent PEG4000, 3-8 parts

[0086] 6-12 parts of inorganic active agent,

[0087] 1-4 parts of dispersant,

[0088] And it is prepared by the following steps:

[0089] The first step, synthetic rubber: the above raw materials are synthesized into rubber through an internal mixer;

[0090] The second step, molding: the synthetic rubber is molded by an open mill;

[0091] The third step, vulcanization: Put the formed rubber into the mold in the vulcanizer, and the pressure range is 150-210kgf / ㎝ 2 , h...

Embodiment 2

[0092] Embodiment 2: The rubber dispersant is a reagent that promotes the uniform dispersion of material particles in the rubber medium to form a stable suspension. The rubber dispersant used in the embodiments of the present invention is one or more of the following reagents: triethylhexyl phosphoric acid, sodium lauryl sulfate, methyl amyl alcohol, cellulose derivatives, polyacrylamide, ancient Er gum, fatty acid polyethylene glycol ester.

Embodiment 3

[0094] The anti-aging agent used in one embodiment of the present invention is: 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline. Its trade name is antiaging agent AW. Antiaging agent AW is a brown viscous liquid, and the pure product is a light brown viscous liquid. Non-toxic, the specific gravity is 1.029~1.030 (25°C), and the boiling point is 169°C. Soluble in benzene, acetone, dioxyethane, carbon tetrachloride, solvent gasoline and ethanol; insoluble in water. Stable in storage. It is a special anti-ozone anti-aging agent, and it also has a protective effect on flex cracking and thermal oxygen aging. Especially suitable for products used under dynamic conditions. No frost, polluting, not suitable for light-colored products. When the dosage is 1 to 2 parts, it has little effect on vulcanization, and when it is increased to 3 parts, it will significantly promote vulcanization, and the amount of promotion should be appropriately reduced during use.

Abstract

The invention discloses a heat-conductive rubber light-emitting diode (LED) lamp; and a spinning socket is fixedly connected with a spinning groove which is arranged on a lamp holder through a spinning device on the spinning socket. A radiator comprises radiating fins. The radiating fins are of arc-shaped structures and are distributed uniformly. A protective hood is of a structure which is made of a light-transmitting material. The protective hood is in a semi-spherical shape. An installation method of an LED bulb comprises the following steps that an LED lamp bead is arranged on a copper substrate through an automatic installation method; the copper substrate which is provided with the LED lamp bead is respectively connected with the protective hood and the radiator through the automatic installation method; and the lamp holder is connected and installed with the radiator by manual assembly through the spinning socket. The product assembly method is more simplified, the production efficiency and the production cost are greatly improved, the service life is greatly prolonged, the raw material mixing is reasonable and the process is simple.

Description

technical field [0001] The invention relates to the technical field of lighting mechanical devices, in particular to a novel heat-conducting rubber LED lamp and a manufacturing method. Background technique [0002] The current LED lighting mostly adopts the method of filament connection, which has the problems of cumbersome production steps, long processing time for production parts, and high production cost. In addition, it also has poor thermal conductivity of materials, unsatisfactory stability, and molding, The problem of poor flame retardancy and insulation performance. Therefore, a LED lighting lamp that can solve the above problems is needed. The material can have good thermal conductivity and stability, and can well solve the problem of molding, flame retardancy and insulation Performance problems, while simplifying the assembly method, improving production efficiency, increasing production costs and service life, so as to meet the needs of actual conditions.
