Embodiment 1

[0045] Use the following weights of ingredients:

[0046]

[0047] Mix polyamide, reinforcing / filling components and processing aids evenly, and feed them into the twin-screw extruder from the main feed, and then mix the flame retardant, anti-copper pollution agent and anti-copper pollution synergist evenly, and feed them from the side Add the twin-screw extruder, and after extruding, drawing, cooling, pelletizing and drying, the nylon flame-retardant material that prevents copper pollution can be obtained. Among them, the aspect ratio of the twin-screw extruder is 36:1, and the temperature of each section of the screw is: the temperature of each working section from the first barrel to the eighth barrel is 265±5°C, 265±5°C, 265°C ±5℃, 265±5℃, 245±5℃, 245±5℃, 245±5℃, 225±5℃, the temperature of the head is 255±5℃.

Embodiment 2

[0049] Use the following weights of ingredients:

[0050]

[0051] The preparation method of the nylon flame-retardant material that prevents copper pollution is the same as in Example 1. The temperature of each section of the screw is: the temperature of each working section from the first barrel to the eighth barrel is 260±5°C, 260±5°C, 260±5°C, 250±5°C, 230±5°C, 230±5°C 5°C, 230±5°C, 230±5°C, the temperature of the machine head is 260±5°C.

Embodiment 3

[0053] Use the following weights of ingredients:

[0054]

[0055]

[0056] The preparation method of the nylon flame-retardant material that prevents copper pollution is the same as in Example 1. The temperature of each section of the screw is: the temperature of each working section from the first barrel to the eighth barrel is 240±5°C, 240±5°C, 240±5°C, 230±5°C, 230±5°C, 230±5°C 5°C, 230±5°C, 230±5°C, the temperature of the machine head is 230±5°C.

Abstract

The invention discloses an application of an anti-copper pollution synergist for improving the anti-copper pollution performance of a nylon flame-retardant material. The raw material composition of the nylon flame-retardant material includes polyamide, a flame retardant and an anti-copper pollution agent. The anti-copper pollution agent is selected from at least one of the anti-oxidation and anti-copper agent ST-697, the anti-oxidation and anti-copper agent 1024, and the raw material composition of the nylon flame retardant material also includes the described anti-copper pollution synergist; The anti-copper pollution synergist includes component A, and the component A is at least one selected from ethylenediaminetetraacetic acid and disodium ethylenediaminetetraacetic acid. In terms of weight percentage, the raw material composition of the nylon flame retardant material includes: 20% to 75% of polyamide, 0.5% to 5% of anti-copper pollution agent, 0.5% to 5% of anti-copper pollution synergist, 10% of flame retardant %~20%, reinforcement / filling component 10%~45%, processing aid 0.5%~5%.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the use of an anti-copper pollution synergist for improving the anti-copper pollution performance of nylon flame-retardant materials. Background technique [0002] Polyamide (commonly known as nylon) materials are widely used in all walks of life after flame retardant and enhanced modification, especially in industrial electrical appliances and household appliances, most of which contain copper-based components. [0003] Nylon materials are easy to absorb water, and some flame retardants, such as brominated flame retardants, red phosphorus flame retardants, organic phosphine flame After high and low temperature and high humidity, some acids will come into contact with copper and copper oxides, and copper ions will appear on the surface of copper metal or plastic. Copper ions are easy to form variegated substances with other substances, such as copper sulfide (black), A...
