Abstract

The invention relates to an environment-friendly nano high-flame-retardant polyester film tape and a manufacturing process thereof. The environment-friendly nano high-flame-retardant polyester film tape comprises a polyester film and nano phosphorus-nitrogen fire retardant attached on the upper surface and the lower surface of the polyester film. The manufacturing process comprises the following steps of: (1) dissolving solid nano phosphorus-nitrogen powder in water to prepare the liquid nano phosphorus-nitrogen fire retardant, and then uniformly spraying the liquid nano phosphorus-nitrogen fire retardant on both sides of the polyster film with a high-pressure spray gun system, (2) allowing the nano phosphorus-nitrogen fire retardant to be tightly attached to the surfaces of the film at high temperature and high pressure, (3) drying in a high temperature oven at 130 DEG C - 170 DEG C and 1-2 negative atmosphere, (4) solidifying and storing the above product at 60 - 70 DEG C for no less than 36 hours, and (5) slitting the product to form a finished product. The environment-friendly nano high-flame-retardant polyester film tape is good in flame resistance, light in gram weight and relatively small in thickness.

Description

Technical field [0001] The invention relates to an environmentally-friendly nano high flame-retardant polyester film tape and its manufacturing process. It is mainly used for bundling and wrapping in the manufacturing process of flame-retardant cables such as flame-retardant mine cables, marine cables, flame-retardant control cables, etc. The role of insulation and flame retardant. Background technique [0002] The flame-retardant layer of the existing polyester film tape is generally thick, and the flame-retardant performance needs to be further improved. After a period of use, the flame-retardant layer attached to the polyester film is also easy to fall off, which makes the polyester film tape resistant. The combustion performance is poor and needs further improvement. Summary of the invention [0003] In view of the above-mentioned defects, the present invention aims to provide an environmentally-friendly nano high flame-retardant polyester film tape with good flame-retard...
