Problems solved by technology

However, the existing binding machine motor mounts are all made of aluminum alloy. The aluminum alloy motor mount has good mechanical properties, but its processing requirements are high, the production cost is high, the efficiency is low, the production cycle is long, and the product yield is low. , and in the long-term operation process, the wear rate is high, the corrosion resistance is poor, and the insulation treatment needs to be improved; on the other hand, the production of aluminum alloy belongs to the field of severe pollution, which has adverse effects on the environment and people's health, and subsequent pollutant treatment Difficult and costly

Abstract

The invention relates to the technical field of engineering plastic, in particular to bookbinding machine motor installation base PBT engineering plastic and a motor installation base. The motor installation base PBT engineering plastic is prepared from the following raw materials in parts by weight: 50 to 70 parts of PBT, 5 to 60 parts of glass fiber, 6 to 12 parts of composite toughening agent, 0.5 to 1 part of lubricant, 20 to 30 parts of composite flame retardant, 1 to 2 parts of weather-proof agent, 1 to 2 parts of antioxidant and 4 to 8 parts of inorganic filler. The bookbinding machine motor installation base PBT engineering plastic prepared in the invention has excellent comprehensive mechanical property and processing property, further has lower dielectric constant and good fire resistance and insulation, can reduce the weight of the motor base when being applied to manufacturing the bookbinding machine motor installation base, improves safety performance, shortens a production and manufacturing period, improves product yield, reduces abrasion and has long service life and excellent comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a PBT engineering plastic for a binding machine motor mounting seat and a drilling motor mounting seat. Background technique [0002] Binding machines are widely used in the binding of paper documents such as bills and archives in various industries, and play an important role in people's daily life and work. When the binding machine is in use, the motor shaft used for drilling is in a state of high-speed rotation, and the motor mount needs to withstand relatively large impacts, so the motor mount has high requirements. However, the existing binding machine motor mounts are all made of aluminum alloy. The aluminum alloy motor mount has good mechanical properties, but its processing requirements are high, the production cost is high, the efficiency is low, the production cycle is long, and the product yield is low. , and in the long-term operation process, the wear r...
