Problems solved by technology

[0003] At present, anti-UV low-smoke, halogen-free and flame-retardant polyolefin sheath materials are widely used in China. The mechanical properties are low, and the surface of the sheath is prone to scratches. Special requirements for sheath wear resistance, oil resistance, and UV-induced sheath degradation when used in harsh environments: In the design of optical cables, it is particularly important to consider the protection of optical fibers under all conditions of use to avoid Additional loss and excessive strain, as well as geometrical changes that affect fiber performance are considered in cable construction

Embodiment 1

[0016] Example 1: A thermoplastic 105°C flame-retardant PVC anti-UV sheath material, prepared from the following raw materials in parts by weight: 45-57 parts of polyvinyl chloride, 2.5-3.5 parts of stabilizer, and 22-28 parts of plasticizer , 2-5 parts of filler, 5-7 parts of flame retardant, 10-15 parts of modifier, 0.7-0.8 part of lubricant, 0.1-0.3 part of antioxidant, 0.4-0.8 part of processing aid, anti-ultraviolet absorption Agent 0.1-0.2 parts, light stabilizer 0.1-0.2 parts.

[0017] The preparation method is as follows: 1) High-mixing kneading: Add polyvinyl chloride, stabilizer, plasticizer, filler, lubricant, processing aid and flame retardant into the high-speed kneader in sequence for adjustment and kneading. When the temperature of the raw materials reaches 110 Add anti-ultraviolet absorber, light stabilizer and modifier at ℃ and stir at high speed, and when the temperature reaches 115℃, discharge to the cold mixer for cooling;

[0018] 2) Extrusion feeding: Wh...

Embodiment 2

[0020] Example 2: A thermoplastic 105°C flame-retardant PVC anti-UV sheath material for optical cables, prepared from the following preferred raw materials in parts by weight: 50 parts of polyvinyl chloride, 2.6 parts of stabilizer, 25 parts of plasticizer, filled 5 parts of additives, 5 parts of flame retardants, 12 parts of modifiers, 0.7 parts of lubricants, 0.1 parts of antioxidants, 0.5 parts of processing aids, 0.1 parts of anti-ultraviolet absorbers, and 0.1 parts of light stabilizers.

[0021] Among them, the stabilizer is calcium zinc stabilizer, the plasticizer is trioctyl trimellitate, the filler is nano-active light calcium carbonate, the flame retardant is antimony trioxide; the modifier is thermoplastic polyurethane. Polyethylene wax is used as the agent, N,N'-1,6-hexylidene-bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamide] is used as the antioxidant, and processing aids Acrylic polymers are selected, 2-(2'-hydroxy-5'-tert-octylphenyl) benzotriazole is selec...

Embodiment 3

[0027] Example 3: A thermoplastic 105°C flame-retardant PVC anti-UV sheath material, prepared from the following preferred raw materials by weight: 55 parts of polyvinyl chloride, 3 parts of stabilizer, 23 parts of plasticizer, and 3 parts of filler 6 parts, 6 parts of flame retardant, 10 parts of modifier, 0.8 part of lubricant, 0.2 part of antioxidant, 0.7 part of processing aid, 0.2 part of anti-ultraviolet absorber, and 0.2 part of light stabilizer.

[0028] Among them, the stabilizer is calcium zinc stabilizer, the plasticizer is trioctyl trimellitate, the filler is nano-active light calcium carbonate, the flame retardant is antimony trioxide; the modifier is thermoplastic polyurethane. Oxidized polyethylene wax was used as the agent, N,N'-1,6-hexylidene-bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamide] was used as the antioxidant, and the processing aid Acrylic polymer is used as the agent, 2-(2'-hydroxy-5'-tert-octylphenyl) benzotriazole is used as the anti-ultravi...

Abstract

A thermoplastic 105°C flame-retardant PVC anti-UV sheath material, prepared from the following raw materials in parts by weight: 45-57 parts of polyvinyl chloride, 2.5-3.5 parts of stabilizer, 22-28 parts of plasticizer, and 2 parts of filler -5 parts, 5-7 parts of flame retardant, 10-15 parts of modifier, 0.7-0.8 part of lubricant, 0.1-0.3 part of antioxidant, 0.4-0.8 part of processing aid, 0.1-0.2 part of anti-ultraviolet absorber parts, light stabilizer 0.1-0.2 parts. The present invention makes the polyvinyl chloride provided by the invention by adding stabilizers, plasticizers, fillers, lubricants, processing aids, flame retardants, antioxidants, anti-ultraviolet absorbers, and light stabilizers to polyvinyl chloride. Light specific gravity, good physical and mechanical properties, excellent UV resistance and mechanical balance; it can meet the working requirements of long-term exposure to ultraviolet rays, and realize environmental protection and flame retardancy; this product has more superior comprehensive properties.

Description

technical field [0001] The invention belongs to the technical field of chemical products, and in particular relates to a thermoplastic 105°C flame-retardant PVC anti-ultraviolet sheath material for optical cables and a preparation method thereof. Background technique [0002] The most commonly used sheath materials in flame-retardant cable sheaths are polyvinyl chloride (PVC, Polyvinyl chloride) and polyolefin (generally PE, polyethylene Polyethylene); however, with the manufacture, installation and To maintain the stability of transmission performance and mechanical strength performance during use, the optical cable sheath may be exposed to imaginable adverse natural or artificial conditions, so the optical cable sheath must be able to adapt to any possible environmental conditions. The flame-retardant cable sheath must have sufficient mechanical strength properties and chemical resistance, and its structure must adapt to the requirements of external conditions. [0003] A...
