Abstract

The invention relates to the technical field of high-polymer materials, in particular to a flame-retardant PA (Polyamide)/PE (Poly Ethylene) alloy material for an electric switch. The flame-retardant PA/PE alloy material for the electric switch is prepared from PA resin, PE resin, a main flame retardant, an auxiliary flame retardant, a compatilizer, a coupling agent and a lubricating agent by high-speed mixing, double-screw extrusion, water cooling, granulation, forced air drying and other procedures. The flame-retardant PA/PE alloy material for the electric switch has the advantages of favorable mobility and stability, wide suitability for injection molding processing of complicated workpieces in various shapes, strong market adaptability, safety and environmental protection, accordance wtih the 'RoHs Instruction', low cost strong international competitiveness, less flame retardant addition, good flame retardance and lower influence on other properties of products.

Description

A kind of electric switch is with fire-retardant PA/PE alloy material
Technical field the present invention relates to technical field of polymer materials, and especially electric switch is with fire-retardant PA/PE alloy material.
The electric switch of background technology herbal has also been cast the protection barrier of safety together for multifarious human consumer when the function service is provided for household electrical appliance.General electric switch materials also must have certain flame retardant properties concurrently except that need satisfying its necessary mechanical property, insulating property and certain resistance toheat.
The acquisition of plastics flame retardant properties depends on the adding of fire retardant, becomes the flame-retardant modified main means of plastics and " addition type " is fire-retardant because of having advantages such as the fire retardant interpolation is convenient, technology is simple, with low cost.Additive flame retardant commonly used is based on halogen system, phosphorus system, nitrogen system, silicon system and metal hydroxides, and to have an addition few and halogenated flame retardant is because of it, and flame retardant effect is obvious, and characteristics such as other performance impacts of goods are little have been obtained using the most widely.Novel halogenated flame retardant not only has the advantage of traditional halogenated flame retardant, and in thermostability, light stability, aspects such as anti-transport property are also very outstanding, makes it become the Polybrominated biphenyl that bans use of in " RoHS instruction " and the ideal substitute of Poly Brominated Diphenyl Ethers.
Electric switch of the present invention is to be that matrix resin forms through modification with PA with fire-retardant PA/PE alloy material, its products machinery performance, wear resistance, insulating property, thermotolerance and flame retardant properties are good, are that a kind of technology is simple, less investment, cost are low, the alloy material of excellent combination property.
Summary of the invention the objective of the invention is to overcome the deficiencies in the prior art, preparation with the electric switch of good mechanical property, insulating property, resistance toheat and flame retardant properties with fire-retardant PA/PE alloy material.
The present invention is achieved through the following technical solutions:
Electric switch of the present invention comprises: PA resin, PE resin, main flame retardant, auxiliary flame retardant, compatilizer, coupling agent, lubricant with fire-retardant PA/PE alloy material.It is characterized in that the mass fraction proportioning of alloy material is:
