Problems solved by technology

Although these flame retardants have been industrialized, there are still problems such as large amount of flame retardant and smoke suppressant, high production cost, low product recycling rate and poor environmental health effects of products, especially the extremely high content of PVC itself. The insurmountable defects in the amount of chlorine and the structure of PVC have made the research and development of new high-efficiency flame retardant and smoke suppressants a difficult point for PVC researchers.

Embodiment 1

[0024] The preparation of embodiment 1 flame retardant coating composition

[0025] The basic formulation of the flame retardant coating composition is shown in the following table:

[0026]

[0027] After mixing the above-mentioned components evenly, melt and blend them on a twin-roller machine at a temperature of 160-170°C for 10 minutes; then hot-press the prepared flame-retardant coating material on a flat vulcanizer at 165-170°C become l0X10X3(mm 3 ), l0X 0l0X2 (mm 3 ), l0mmx l0X1(mm 3 ) flat plate, or use a slicer to cut into shape according to the standard and then use it for various tests.

Embodiment 2

[0029] The flame retardant coating composition 2 was prepared according to the same method as above, wherein no flame retardant and smoke suppressant was added.

[0030] Limiting Oxygen Index (LOI) Test

[0031] HC-2 oxygen index measuring instrument, Jiangning Analytical Instrument Factory. Process the sample into 100mmx6.5mmx3.0mm 3 For the sample, the oxygen index of the sample is measured according to GB / T2406-96 (Test method for combustion performance of plastics - oxygen index method).

[0032] The LOI of the flame retardant coating composition of Example 1 is 38.6, and the LOI of the flame retardant coating composition of Example 2 is 13.1.

Abstract

The invention provides a flame retardant coating composition for cables. The composition comprises basic resin and a flame retardant smoke inhibitor. The chemical structure of the flame retardant smoke inhibitor is represented in the description. For 100 parts by weight of basic resin, there is 5 to 30 parts by weight of flame retardant smoke inhibitor. The provided coating composition has an excellent flame retardant performance, an excellent mechanical property, and an excellent high temperature resistant performance.

Description

technical field [0001] The invention relates to the field of cables, more specifically to a flame-retardant coating composition for cables. Background technique [0002] In order to reduce the occurrence and development of fire, people have conducted various discussions on the flame retardant and low smoke of wire and cable. The best way to achieve flame retardancy, low smoke, and heat resistance of cable materials is to choose polymer materials that have these characteristics. PVC resin is currently the most used because of its extremely high electrical insulation (such as electrical breakdown resistance, which can be used for 10,000 volt low-voltage cables), relatively aging resistance, chemical stability, wear resistance and low price. Raw materials for cable materials. About 20% of the PVC resin produced in my country every year is used for cable materials. However, when PVC resin burns, it releases toxic and harmful gases such as hydrogen chloride, carbon monoxide, c...
