preparation example Construction

[0033] Preparation of modified solution: Add 200mL of 5% silver nitrate solution into a beaker, then slowly add excess 1% sodium hydroxide aqueous solution, and keep stirring for 10min to react. Take out the precipitate and put it in a clean beaker, slowly add 80ml of 3% ammonia water dropwise to dissolve the precipitate;

[0034] Modification of glass fiber: put the treated glass fiber into 80ml of modification solution, put no more than 50g of glass fiber into it, ultrasonically disperse while stirring constantly to suspend the glass fiber fully in the solution, then slowly add in drops 80ml of 10% glucose aqueous solution is reacted in a hot water bath at 65° C. for more than 10 minutes, washed with water and filtered to obtain a modified glass fiber coated with silver on the surface.

Embodiment 1

[0036] (1) Prepare materials according to the following components and parts by weight:

[0037]

[0038] Among them, the matrix resin is PA6 CM1017 of Toray Corporation of Japan;

[0039] Wear-resisting agent is polytetrafluoroethylene PTFE, micron grade, commercially available;

[0040] The antioxidant is Irganox B900;

[0041] The lubricant is polyethylene wax;

[0042] (2) Mix the above-mentioned raw materials except glass fiber into the high-speed mixer according to the above ratio and stir. After mixing evenly, feed it into the twin-screw extruder through the metering device. The glass fiber is processed by side feeding, and the barrel temperature is set. The temperature is 200°C-240°C, through shearing and plasticizing, mixing the materials evenly, and then granulating to obtain the desired wear-resistant conductive polyamide composition.

Abstract

The invention discloses a wear-resistant conductive polyamide composite material and a preparation method thereof. The material comprises the following components in parts by weight: 35-92 parts of matrix polyamide resin, 3-15 parts of an anti-wear agent, 5-50 parts of modified chopped glass fibers, 0.1-1 part of an antioxidant and 0.5-2 parts of a lubricant. The modified chopped glass fibers aremodified chopped glass fibers with the surfaces coated with silver. According to the invention, the surface of the glass fibers is coated with metal silver, so that the modified glass fibers with conductivity are obtained; meanwhile, the wear-resistant agent is added to prolong the service life of the polyamide material; the prepared composition has relatively high degree of freedom of color matching.

Description

technical field [0001] The invention relates to a polyamide composite material and a preparation method thereof, in particular to a wear-resistant conductive polyamide composite material and a preparation method thereof; in particular to a wear-resistant conductive polyamide material with high color matching freedom, excellent electrical conductivity and service life Polyamide composite material and method for its preparation. Background technique [0002] At present, the oil resources on the earth are getting less and less, and all walks of life are actively contributing to energy conservation and emission reduction. It is becoming increasingly important to use plastic instead of steel to reduce the weight of automobiles, machinery, and household appliances. Polyamide materials play a very important role in our lives, such as daily necessities such as clothes, electrical appliances, toys, industrial supplies such as gears, bearings, and auto parts, and are even widely used ...
