Problems solved by technology

Although fluorine materials (FKM, PVDF materials) have excellent oil resistance, solvent resistance, and high temperature resistance, they are expensive, low temperature resistance, and poor material flexibility, which greatly limit their wide application.
Although the polyester heat shrinkable sleeve has excellent oil resistance and flexibility, the defect of easy hydrolysis of the polyester group also limits the wide range of applications.

Abstract

The invention discloses a polyether block amide thermal shrinkable sleeve pipe. The polyether block amide thermal shrinkable sleeve pipe is composed of, by weight, 70 to 90 parts of a polyether blockamide elastomer, 10 to 30 parts of a polyether block polyester elastomer, 20 to 50 parts of a fire retardant, 10 to 25 parts of a flame resistance synergistic agent, 1 to 4 parts of a lubricant, 1 to4 parts of an anti-oxidant, 5 to 10 parts of a color master batch, and 1 to 2 parts of an antiseptic; the polyether block amide elastomer is one, or a mixture of two or more ingredients obtained via block polymerization of polyamide block dodecanol lactam or caprolactam, or polyether block polyethylene glycol (PEG); the polyether block polyester elastomer is one, or a mixture of two or more ingredients obtained via block polymerization of polyester block polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyether block polyethylene glycol (PEG), polypropylene glycol (PPG),and polytetramethylene glycol (PTMG). The polyether block amide thermal shrinkable sleeve pipe possesses following advantages: wear resistance, oil resistance, low temperature resistance, and antistatic performance are excellent, and the application range is wide.

Description

technical field [0001] The invention relates to a polyether block amide heat-shrinkable sleeve, which has excellent oil resistance and friction resistance compared with traditional polyolefin heat-shrinkable sleeves, and compared with expensive oil-resistant, high-temperature-resistant fluorine-like material heat-shrinkable sleeves It has excellent low temperature resistance, soft performance and cost advantages. Background technique [0002] With the development of heat-shrinkable technology, the heat-shrinkable materials used in the fields of ships, locomotives, and aviation are mainly polyolefins and fluorine materials. Between polyolefins and fluorine materials, polyolefins do not have advantages in oil resistance, high temperature resistance, and mechanical friction resistance. Although fluorine materials (FKM, PVDF materials) have excellent oil resistance, solvent resistance, and high temperature resistance, they are expensive, low temperature resistance, and poor mat...
