Anti-freezing and heat-insulation PDU (power distribution unit) wire bundle sheath material and preparation method thereof

Abstract

The invention discloses an anti-freezing and heat-insulation PDU (power distribution unit) wire bundle sheath material. The anti-freezing and heat-insulation PDU wire bundle sheath material is prepared from the following raw materials in parts by weight: 5 to 7 parts of rosin, 3 to 5 parts of tris nonyl phosphite phenyl ester, 40 to 50 parts of butyl methacrylate, 20 to 30 parts of methyl acrylate, 4 to 6 parts of sodium peroxide, 3 to 5 parts of palm wax, 0.7 to 1 part of benzotriazole, 3 to 5 parts of ricinoleic acid, 0.6 to 1 part of zinc dialkyl dithiophosphate, 10 to 14 parts of carbon fiber, 3 to 4 parts of hollow glass microsphere, 0.1 to 0.2 part of sp-80, 2 to 3 parts of hydroxyethyl cellulose, and 140 to 170 parts of polyvinyl chloride. The anti-freezing and heat-insulation PDU wire bundle sheath material has the advantages that the added hollow glass microsphere is coated, so that the easiness in cracking is avoided; the anti-freezing and heat-insulation effects are good; the anti-freezing and heat-insulation PDU wire bundle sheath material is suitable for cold areas, the service life is long, and the comprehensive property is excellent.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a frost-resistant and heat-preserving PDU wire harness sheath material and a preparation method thereof. Background technique [0002] PDU is also what we often call the power distribution socket for cabinets. PDU is a product designed to provide power distribution for cabinet-mounted electrical equipment. With the development of computer network technology, the demand for key equipment such as servers, switches, and various electronic equipment It is also increasing day by day, the business it undertakes is becoming more and more critical, and the requirements for the environment where the equipment is located (such as computer room, cabinet, etc.) are also higher. All facilities involved in the operation of key equipment must have high reliability and availability. For the power socket, it is the last pass for all equipment to use electricity. If it is not stable enough and...

Problems solved by technology

For the power socket, it is the last pass for all equipment to use electricity. If it is not stable enough and lacks sufficient protection functions, it may cause expensive equipment to be destroyed or even the entire system to collapse; therefore, if the use of PDU itself is improved Safety performance is also the focus of current research, and the wire harness sheath of the PDU has a good protective effect, and it is particularly necessary to further improve the safety of the wire harness sheath material

At the same time, in order to improve the mechanical strength of the sheath material, various inorganic fillers are often added to it, but the compatibility between the inorganic filler and the polymer matrix is ​​poor, and it is easy to form agglomerates, so the stability of the material cannot be guaranteed.

At present, a large number of sheath materials are used in low temperature and cold regions. These sheath materials are subjected to low temperature for a long time, and they are prone to frost cracking, which affects the safety performance of use.
