Problems solved by technology

The commonly used alumina coating method for chemical fiber webbing is to mix benzene organic solvents, pigments and alumina powder, and then heat to volatilize and dry the organic matter. The alumina coating produced in this way is also easy to fall off after friction, and Coating process causes environmental pollution
Since the alumina powder material as a coating is not easy to combine wit...

Embodiment Construction

[0012] specific implementation plan

[0013] (1) Open the gate valves 5 and 6 between each chamber, open the discharge door 4, put the raw material tape winding shaft 12 wrapped with chemical fiber webbing into the raw material chamber 2 and fix it, pull out the chemical fiber webbing 14 and pass through the deposition chamber 1 to receive the coating. On the coating tape winding shaft 13 of the layer chamber 3, the rotation of the coating tape winding shaft 13 can make the chemical fiber webbing 14 enter the coating chamber 3 through the deposition chamber 1. Close the switch 15 of the discharge door 4, the alkyl aluminum tank 9, the oxygen-enriched air input pipe, the alumina storage tank 11, and the reclaiming door 7.

[0014] (2) Start the vacuum pump 8 to evacuate the three connected chambers to reach 10 -3 Turn off the vacuum pump 8 after Pa.

[0015] (3) Open the alkylaluminum tank 9 and pass the alkylaluminum gas into the deposition chamber 1 to keep the volume conce...

Abstract

The invention discloses a method and device for attaching an inflaming retarding aluminum oxide coating to the surface layer of chemical fiber braid. The device is composed of a raw material chamber,a PECVD deposition chamber, a coating chamber and an appendant; the chambers can be separated and communicated through opening and closing of a gate valve. The chemical fiber braid is subject to aluminum alkyl PECVD gas phase deposition to generate an aluminum thin film on the surface layer, the coating chamber absorbs aluminum oxide powder for gathering wrapping, and oxygen-enriched air is inputto carry out deep oxidation to form an amorphous aluminum oxide thin film layer.

Description

technical field [0001] The invention provides a method and a device for coating the surface of a chemical fiber webbing with an aluminum oxide film layer, so as to play the roles of antistatic, improving strength, flame retardancy and easy coloring on the surface of the webbing, and belongs to the technical field of flame retardant material coating. Background technique [0002] The webbing for bundling goods is woven with modified chemical fibers such as polypropylene and polyester, which have quite strict anti-static, flame-retardant and coloring requirements. Alumina powder is an inorganic material with good insulation, flame retardant and heat insulation properties. It can be used on the surface of chemical fiber webbing to improve the strength and prevent splitting. It is also a coloring intermediate of environmentally friendly pigments. The commonly used alumina coating method for chemical fiber webbing is to mix benzene organic solvents, pigments and alumina powder, a...
