Problems solved by technology

The sheath materials using EVA (ethylene-vinyl acetate copolymer) as the base material are now radiation cross-linked. Due to factors such as cross-linking degree and VA (vinyl acetate) content, their oil resistance cannot meet the mud-resistant cable standard. The requirements of the sheath material in NEK606, now the new Evapine (EVM) rubber produced by Lanxess Chemical in Germany has high VA content, good oil resistance, can be made into vulcanized rubber, achieves a high degree of cross-linking and can meet NEK606 Medium oil resistance performance requirements, but the problem is that when the rubber material is used on the cable, it must meet the basic mechanical performance requirements of the cable to the sheath material. The performance here is particularly prominent in the low elongation and poor tear resistance.
At present, the elongation of rubber made of EVM is difficult to exceed 200%, and the tear strength is 3.0-5.0n / mm, which is difficult to be used for drilling platforms.

preparation example Construction

[0017] A preparation method of a mud resistant cable sheath rubber material, comprising the following steps:

[0018] (1) Raw rubber: take the Yihuaping rubber of the formula quantity and add it to the internal mixer or open mill for mastication, and add the release agent of the formula quantity during mastication to obtain the raw rubber;

[0019] (2) Mixing: After the plasticized raw rubber is pressed down for 30 seconds with the top bolt in the internal mixer, the formula amount of flame retardant Al(OH) 3 , stearic acid, anti-aging agent, plasticizer, reinforcing filler and half the weight of flame retardant Mg(OH) 2 Put it into the internal mixer and drop the top pin to mix for 30S, then lift up the top pin and add the remaining flame retardant Mg(OH) 2 , and press down the top bolt for 40 seconds, lift up the top bolt to clean the pressure hammer, then press down the top bolt until the temperature reaches 125°C to obtain a mixture;

[0020] (3) Put the mixed material p...

Abstract

The invention relates to the technical field of novel materials, in particular to a mud-resistant cable sheath rubber material. The mud-resistant cable sheath rubber material is prepared from, by weight, 100 parts of levapren rubber, 2.5-6.5 parts of vulcanizing agents, 0.5-1.5 parts of accelerant, 90-145 parts of fire retardant, 1.0-2.0 parts of release agents, 1.0-2.0 parts of stearic acid, 0.5-1.0 part of anti-aging agents, 1.5-2.0 parts of coupling agents, 1.5-13.5 parts of plasticizer and 5.0-10.0 parts of reinforcing filler. The prepared mud-resistant cable sheath rubber material has excellent rubber elasticity and good crack resistance and is applicable to drilling platforms.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a mud-resistant cable sheath rubber material and a preparation method thereof. Background technique [0002] Mud-resistant cables used on drilling platforms are required to be low-smoke, halogen-free, flame-retardant, and oil-resistant. The sheath materials using EVA (ethylene-vinyl acetate copolymer) as the base material are now radiation cross-linked. Due to factors such as cross-linking degree and VA (vinyl acetate) content, their oil resistance cannot meet the mud-resistant cable standard. The requirements of the sheath material in NEK606, now the new Evapine (EVM) rubber produced by Lanxess Chemical in Germany has high VA content, good oil resistance, can be made into vulcanized rubber, achieves a high degree of cross-linking and can meet NEK606 Medium oil resistance performance requirements, but the existing problem is that when the rubber material is use...
