Abstract

The invention discloses a titanium sol modified flame-retardant optical cable material, which is prepared from the following raw materials in parts by weight: 10 to 13 parts of talcum powder, 1 to 2 parts of calcium aluminate, 4 to 5 parts of polytetrafluoroethylene wax, 0.4 to 1 part of potassium perfluorobutanesulfonate, 2 to 3 parts of epoxidized soybean oil, 100 to 130 parts of polyvinyl chloride, 20 to 27 parts of polystyrene, 3 to 4 parts of sodium hypophosphite hydrate, 2 to 3 parts of paraformaldehyde, 0.2 to 0.3 part of 35-37-percent hydrochloric acid, 4 to 6 parts of dichloropentate, 5 to 7 parts of aluminum chloride hexahydrate, 0.1 to 0.2 part of triethylamine, 2 to 3 parts of tetrabutyl titanate, 0.1 to 0.4 part of polyglycerol fatty acid ester, 1 to 2 parts of magnesium sulfate, 0.8 to 1 part of hydroxyethyl cellulose, 2 to 3 parts of calcium lactobionate and 1 to 2 parts of acetic acid. The titanium sol modified flame-retardant optical cable material has the advantages that the effects of diluting flame and reducing temperature in a burning region can be achieved; in addition, free radicals generated during polystyrene chain segment cracking can be captured through some phosphorous oxide free radials and the like generated during the cracking; the thermal stability of the material is improved; the heat release value of the material is reduced.

Description

technical field [0001] The invention relates to the technical field of optical cable materials, in particular to a titanium sol modified flame-retardant optical cable material and a preparation method thereof. Background technique [0002] In recent years, nanotechnology has attracted widespread attention in the field of flame retardancy. Studies have shown that nanomaterials only need a small amount of addition (generally less than 5%) to achieve a more obvious flame retardancy effect. Therefore, the preparation of flame-retardant nanocomposites is an important component in the field of flame-retardant technology, and is highly regarded by researchers. Layered inorganic nanomaterials are one of the most effective filler materials in flame-retardant nanocomposites. When layered inorganic nanomaterials are dispersed in the polymer matrix at the nanoscale, they can significantly improve the mechanical properties of nanocomposites. , thermal stability and flame retardant prope...
