Abstract

The invention discloses a flame-retardant reinforced PBT material used for a wiring terminal insulation base with high drawing force and a preparation method thereof. The flame-retardant reinforced PBT material is composed of the following raw materials in percentages by mass: 40 to 60% of PBT resin, 10 to 20% of a flame-retardant auxiliary agent, 20 to 35% of a reinforcing material, 2 to 5% of aflexibilizer, 0.2 to 1% of a lubricant and 0.2 to 1% of an anti-oxidation auxiliary agent. The invention also discloses a preparation method for the flame-retardant reinforced PBT material used for the wiring terminal insulation base with high drawing force at the same time. The flame-retardant reinforced PBT material used for the wiring terminal insulation base with high drawing force provided bythe invention has excellent mechanical properties; and the wiring terminal insulation base prepared from the flame-retardant reinforced PBT material provided by the invention has high drawing force and is not prone to shedding in the assembling, transportation and application processes of a wiring terminal, so potential safety hazards are eliminated. The preparation method for the PBT material provided by the invention has the advantages of simple process, less investment, low energy consumption, high efficiency and significant economic and social benefits.

Description

technical field [0001] The invention relates to a flame-retardant reinforced PBT material for an insulating base of a terminal with high pull-out force and a preparation method thereof. Background technique [0002] The terminal block is used to facilitate the connection of wires. It is a cylindrical metal insert sealed in an insulating plastic base. There are holes at both ends for inserting wires. There are screws for fastening or loosening, such as two Wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time without having to weld or twist them together, which is convenient and quick to use. [0003] As an indispensable electrical connector in the electrification process, terminal blocks are widely used, and the materials for making their insulating bases are also very particular. Among them, increasing the pull-out force between the metal insert and the inner wall o...
