Problems solved by technology

At present, the flame retardants commonly used in nylon will greatly affect the transparency of nylon when used, and cannot meet the application requirements
Moreover, when the UL94 1.6mm V0 flame retardant requirements are met, the addition of a large amount of flame retardants will cause a serious decrease in the toughness of nylon, which will bring obvious side effects
At the same time, the material has to withstand extreme environments such as mountains, plateaus, and deserts. This requires transparent flame-retardant nylon materials to withstand the test of ultra-high temperature (over 85°C for a long time) and ultra-low temperature (minus 50°C or below for a long time) in the application environment. , but also have low moisture absorption and high dimensional stability, which have not yet been effectively realized

Embodiment Construction

[0026] Below in conjunction with embodiment the present invention is described in further detail.

[0027] A preparation method of a transparent flame-retardant nylon material, comprising the following steps:

[0028] (1) 75-95 parts of nylon, 0.5-5 parts of transparency improver, 0.5-5 parts of compatibilizer, 5-15 parts of flame retardant, 1-6 parts of flame retardant synergist, and 0.3-5 parts of other additives 1 part, mixed according to parts by weight to form a mixture, put into a high-speed mixer and mix for 1-3min to obtain a mixture;

[0029] (2) Add the mixture obtained in step (1) into the twin-screw extruder through the hopper, and at the same time, add 1-10 parts of glass fiber through the side feeding port, and at 210-300 ° C, undergo extrusion, Stranding, traction, and granulation are prepared into transparent flame-retardant nylon materials.

[0030] The nylon material is one or a mixture of nylon 12, nylon 6, nylon 66, nylon 6I, nylon 6T, nylon 9T, and nylon...

Abstract

The invention relates to a nylon material and a preparation method thereof, in particular to a transparent flame-retardant nylon material and a preparation method thereof. The material of the present invention comprises the following components in parts by weight: 75-95 parts of nylon, 1-10 parts of glass fiber, 0.5-5 parts of transparency improver, 5-15 parts of flame retardant, and 1-15 parts of flame retardant synergist 6 parts, 0.5-5 parts of compatibilizer, 0.3-1 part of other additives. The flame retardant grade of the transparent flame retardant nylon material of the present invention reaches UL 94 1.6mm V0 level, the transparency exceeds 90%, low water absorption, excellent mechanical and heat resistance properties, good oil resistance, good high and low temperature resistance performance, and high dimensional stability , The appearance is flat and smooth, and it can be recycled. It is used to prepare high-end applications such as high-end mobile communication device casings, automotive oil cups, aerospace instruments, and high-end electronic appliances that require high fire protection and transparency. In addition, the product process is easy for industrial production.

Description

technical field [0001] The invention relates to a nylon material and a preparation method thereof, in particular to a transparent flame-retardant nylon material and a preparation method thereof, belonging to the field of material technology. Background technique [0002] With the increasing development of transportation and electronic communication industries, there are clear requirements for the flame retardant grade of nylon parts, and the materials are required to maintain good light transmission and oil resistance, such as automotive oil cups and aviation instruments. This requires flame retardant modification of nylon while achieving higher transparency. At present, the flame retardants commonly used in nylon will greatly affect the transparency of nylon when used, and cannot meet the application requirements. Moreover, when the UL94 1.6mm V0 flame retardant requirements are met, the addition of a large amount of flame retardants will cause a serious decrease in the to...
