Problems solved by technology

[0003] Although the prior art has been reported to be used in the outer sheath of wind energy cables, the basic materials such as polyethylene or polyurethane used in the prior art lead to poor softness, poor weather resistance, oil resistance and resistance to moisture at room temperature. Not very flammable

Embodiment 1

[0066] Preparation:

[0067] First take 200 grams of base rubber, knead on a small open mill, fully cover the rolls, add chlorosulfonated polyethylene rubber base rubber, acid acceptor, reinforcing agent, flame retardant, anti-aging agent, process operating agent, and some fillers As well as flame retardant plasticizers, cold-resistant plasticizers, etc. After basic molding, add the remaining fillers, flame-retardant plasticizers, and cold-resistant plasticizers, and then add vulcanizing agents, vulcanization aids, and vulcanization accelerators after molding. The distance between the rollers is reduced at the small start-up, and the rubber is punched into thin sheets, and the triangle bag is punched at least 3 times, and the thickness of the sheet is about 5mm, and then cooled for later use.

Embodiment 2

[0069] Put 40kg of the basic rubber that has been masticated into the internal mixer for 30 seconds to 1 minute, then add acid acceptor, flame retardant plasticizer, cold-resistant plasticizer, reinforcing agent, flame retardant, anti-aging agent, process Operating agents, fillers, flame retardant plasticizers, cold-resistant plasticizers, etc. excluding vulcanizing agents, vulcanization aids, and vulcanization accelerators, etc. 47.75 kg of compounding ingredients, after mixing for about 5 minutes, discharge the material, press the tablet and open the filter After the rubber is weighed, it is coiled and cooled, and each sulfur-free rubber roll is 21.94 kg. After parking for at least 2 hours, weigh 4 unvulcanized rubber rolls and put them into the internal mixer for about 3 minutes, then add 2.25 kg of vulcanizing agent, vulcanization assistant, and vulcanization accelerator for 30 seconds to 1 minute. Afterwards, the strips are turned and cooled, and the thickness of the stri...

Abstract

The invention discloses an external rubber sleeve material of a cable used for wind power generation, comprising the following components by weight parts: 100.00 parts of chlorosulfonated polyethylene rubber, 15.00-20.00 parts of vulcanizing agent epoxy resin, 5.00-10.00 parts of magnesium oxide acid acceptor, 1.00-1.50 parts of vulcanization aid, 0.20-1.50 parts of vulcanization accelerator, 10.00-15.00 parts of fire-retardant plasticizer, 5.00-10.00 parts of cold resistant plasticizer, 30.00-40.00 parts of reinforcing agent, 40.00-50.00 parts of filling agent, 0.50-2.00 parts of anti-ageing agent, 0.50-2.00 parts of process operation agent, and 10.00-15.00 parts of flame retardant. The external rubber sleeve material of the cable used for wind power generation has the greatest advantages of extremely high physical and mechanical performance, excellent oil resistance and climate resistance, extremely softness and flame retarding, and the like.

Description

technical field [0001] The invention relates to the technical field of cable material polymers, in particular to an outer rubber sheath material of a cable for wind power generation. Background technique [0002] At present, wind energy is the most energy-saving and environmentally friendly, and there are inexhaustible wind energy resources in nature, but the cable accessories for wind power generation cannot keep up with the requirements of wind power generation. At present, the wind energy cables used in the market are not effective. Too ideal, mainly because the sheath material of the wind energy cable is polyethylene or polyurethane and other polymer crystalline materials with plastic properties, which will cause the wind energy cable to crack in the natural low temperature environment when used outdoors, become brittle and cracked due to ultraviolet aging, and acid The physical and mechanical properties of the sheath after alkali corrosion are extremely poor; the specia...
