Abstract

The invention discloses durable modified PA12 rubber being composed of PA12 plastic, a filling agent, a photo stabilizer, a heat stabilizer, a coupling agent and a nucleating agent. The filling agent is glass fiber; the photo stabilizer is titanium oxide; the heat stabilizer is zinc laurate; the coupling agent is titanium triisostearoylisopropoxide; and the nucleating agent is butadiene rubber. The PA12 rubber particularly includes, by weight, 90-98 parts of the PA12 plastic, 31-36 parts of the glass fiber, 4-9 parts of the titanium oxide, 6-10 parts of the zinc laurate, 8-13 parts of the titanium triisostearoylisopropoxide, and 17-22 parts of the butadiene rubber. The PA12 rubber is low in water absorption rate and good in anti-aging property, is convenient to process, and has good thermo-stability and high strength.

Description

technical field [0001] The invention relates to the field of rubber and plastics, in particular to a durable modified PA12 rubber. Background technique [0002] The scientific name of PA12 is polylaurolactam, also known as nylon 12. The basic raw material for its polymerization is butadiene, which can rely on petrochemicals. It is a semi-crystalline-crystalline thermoplastic material with good electrical insulation, good impact resistance and chemical stability. However, it has the characteristics of easy water absorption and poor light resistance, and its own strength is easily reduced during the modification process. Contents of the invention [0003] The purpose of the present invention is to provide a durable modified PA12 rubber with the characteristics of low water absorption, good aging resistance, convenient processing, good thermal stability and high strength. [0004] The technical solution of the present invention is that a durable modified PA12 rubber is com...
