Phosphatized nano pdu wire harness sheath material and preparation method thereof

Abstract

The invention discloses a phosphatized nano pdu wire harness sheath material. The phosphatized nano pdu wire harness sheath material is prepared from the following raw materials in parts by weight: 35to 40 parts of methyl methacrylate, 25 to 31 parts of glycidol, 140 to 150 parts of polyvinyl chloride, 0.7 to 1 part of a silane coupling agent kh550, 10 to 12 parts of nano silicon dioxide, 3 to 4parts of alkanolamide, 1 to 2 parts of sodium diacetate, 0.8 to 1 part of an amine catalyst, 0.1 to 0.2 part of lithium methoxide, 7 to 9 parts of phosphorus trichloride, 10 to 14 parts of pentaerythritol, 0.8 to 1 part of sucrose acetate isobutyrate, 0.1 to 0.2 part of p-toluene sulfonic acid and 2 to 3 parts of barium stearate. According to the phosphatized nano pdu wire harness sheath material,phosphorus is doped and the material has a certain fireproof and flame-retarding effect, so that the comprehensive performance of a finished-product material is improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a phosphating nano-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 lacks sufficient p...

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.
