Problems solved by technology

A single anti-aging agent ODA has a good protective effect on heat, oxygen and flex fatigue aging, and it can also enhance its anti-ozone ability in chloroprene rubber, but a single anti-aging agent cannot completely achieve comprehensive protection in practice effect, while various anti-aging agents will produce additive and synergistic effects when mixed together, which can solve various aging protection problems, and can obtain synergistic effects when used properly

Embodiment 1

[0019] An anti-aging agent for static cables, comprising the following components in parts by weight: 40-50 parts by weight of anti-aging agent ODA, 10-15 parts by weight of anti-aging agent DFC-34, 15-20 parts by weight of anti-aging agent MB, rubber 0.1-0.3 parts by weight of accelerator, wherein the ratio of parts by weight between anti-aging agent ODA, anti-aging agent DFC-34 and anti-aging agent MB is 4-5:1-1.5:1.5-2; The weight ratio of different components has various ratios, as shown in the table below, the ratio with better practical effect is: the weight ratio of anti-aging agent ODA, anti-aging agent DFC-34 and anti-aging agent MB is 40 :10:18.

[0020]

[0021] The anti-aging agent ODA of the present invention is the reaction product of diphenylamine and diisobutylene, which has a good anti-atmospheric aging effect. The anti-aging agent DFC-34 is 34% styrenated diphenylamine condensate+66% Light calcium, with good thermal oxidation resistance and crack resistan...

Embodiment 2

[0023] The elastic carrier of the present invention is one or more mixtures of natural rubber, styrene-butadiene rubber, nitrile rubber, and chloroprene rubber. The preferred elastic carrier is 8-12 parts by weight. The elastic carrier is used to assist various The anti-aging agent is mixed and attached to form.

[0024] The dispersant of the present invention is one or two mixtures in liquid paraffin and microcrystalline wax, and the preferred dispersant is 1-5 parts by weight, and the dispersion effect of the elastic carrier and antiaging agent mixture is improved by the dispersant, because Static cables require greater strength, so stearic acid is not used as a dispersant.

[0025] The ratio of parts by weight of the elastic carrier of the present invention to the rubber accelerator is 10:0.2, and the rubber accelerator is used to improve the modulus stress of the carrier, which can ensure the molding effect of the fixed particles of the anti-aging agent, and the large cont...

Embodiment 3

[0027] A kind of preparation steps of antiaging agent of static cable:

[0028] 1) After mixing anti-aging agent ODA, anti-aging agent DFC-34 and anti-aging agent MB in sequence, heat, melt and stir under reduced pressure and low temperature, and the temperature does not exceed 50°C; since anti-aging agent DFC-34 is a solid mixture, it contains 33% light calcium is prone to side reactions under high temperature conditions, and it is melted by heating under reduced pressure.

[0029] 2) Heat and melt the elastic carrier at the same time, add heated rubber oil and rubber accelerator and stir for 30 minutes to react; this reaction is also carried out under the condition of vacuum and decompression.

[0030] 3) Add the mixed extended elastic carrier to the anti-aging agent mixture while it is hot, and add the dispersant while stirring, react for 1 hour, gradually reduce the reaction temperature, and cool to form a solid mixture.

[0031] 4) Stir the cooled mixture through a jet m...

Abstract

The invention discloses an anti-aging agent of a static cable and a preparation method thereof. The anti-aging agent comprises the following components in parts by weight: 40 to 50 parts of an anti-aging agent ODA, 10 to 15 parts of an anti-aging agent DFC-34, 15 to 20 parts of an anti-aging agent MB and 0.1 to 0.3 part of a rubber promoter, wherein the weight part ratio of the anti-aging agent ODA to the anti-aging agent DFC-34 to the anti-aging agent MB is (4-5): (1-1.5): (1.5-2). The anti-aging agent of the cable is prepared by mixing the different anti-aging agents, through the synergistic effect of the anti-aging agents, the thermal-oxidation resistance, the fracturing resistance, the atmospheric aging resistance and the ultraviolet resistance of the anti-aging agent of the cable are good, the blooming phenomenon is unlikely to happen when the anti-aging agent of the cable is fused into rubber, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of preparation of fine chemicals, in particular to a high-efficiency antioxidant for static rubber products and cables and a preparation method thereof. Background technique [0002] The aging of rubber can gradually reduce the performance of its products so that it completely loses its use value; for the service life of rubber belt products, it is necessary to add some substances that can inhibit the aging process in the rubber adhesive, thereby prolonging the storage period of rubber products and service life. [0003] The rubber layer of the static cable includes an insulating layer and a sheath. It is made of natural rubber, styrene-butadiene rubber, ethylene-propylene rubber, etc. In addition to meeting the insulation performance and physical and mechanical properties, it requires aging resistance and wear resistance. Some products require oil resistance and flame retardancy. . There are many types of...
