Special nylon material for switch and preparation method of material

Abstract

The invention discloses a special nylon material for a switch. The special nylon material is prepared from, by weight, 75-80 parts of nylon resin, 5-10 parts of polyimide, 4-10 parts of nano-silica, 3-5 parts of silicate, 5-15 parts of phenolic resin, 3-10 parts of fiberglass, 3-10 parts of lubricant, 6-14 parts of auxiliaries. The materials above are mixed and heated, and then extruded, cooled and granulated through a twin-screw, a switch-specific nylon material can be obtained. The invention provides a switch-specific nylon material, which is superior to the existing products, whether in the level of stretch, compression degree, notched punch strength, heat distortion temperature, or friction coefficient, thermal conductivity and water absorption. The nylon material is applied to switch products and has the advantages of obvious flame retardant performance enhancement and excellent mechanical properties.

Description

technical field [0001] The invention relates to a manipulator, in particular to a special nylon material for switches and a preparation method thereof. Background technique [0002] The material selection of the switch is very critical, because when the temperature of the switch is too high due to a short circuit in the circuit or a large current, the switch will melt or even catch fire. On the market, nylon materials are often used to make the mold inside the switch. [0003] Nylon is one of the three major synthetic fibers and is widely used in manufacturing because of its good thermodynamic properties, light weight and corrosion resistance. However, in recent years, it has been proved that nylon materials also have disadvantages such as poor flame retardancy, low mechanical strength, low notched impact strength, and low heat distortion temperature. Therefore, more and more attention has been paid to improving nylon products. Contents of the invention [0004] The obje...
