Problems solved by technology

The other type is dedicated to the flame retardant of the cable itself, so as to manufacture various cables that can flame-retardant flame spread when a fire burns. The conventional flame-retardant cables use inorganic flame-retardant fillers such as aluminum hydroxide or magnesium hydroxide. , which greatly increases the density of the cable material, increases the self-weight, and improves the processing requirements of the product, because aluminum hydroxide is easy to tap under the processing temperature, and the flame retardancy of the product will be great. Reduced to a certain extent

Embodiment 1

[0021] The weight formula composition of cable flame retardant material:

[0022]

[0023]

[0024] Stir and mix the basic resin ethylene-vinyl acetate copolymer (EVA) and white oil evenly, and then mix this material with microencapsulated red phosphorus and other flame retardants, antioxidants, dispersants, coupling agents, etc. at a low speed ( 100-200r / min) to stir and mix evenly, and then use a twin-screw extruder to extrude and granulate to obtain a blend. Then put the blend in a 1mm-thick mold frame, preheat it on a molding machine (upper and lower mold temperature 180°C) for 6 minutes, heat press it at a pressure of 5.0 MPa for 4 minutes, and then cold press it at 10.0 MPa to room temperature. Obtained dry.

Embodiment 2

[0026] The weight formula composition of cable flame retardant material:

[0027]

Embodiment 3

[0029] The weight formula composition of cable flame retardant material:

[0030]

[0031] The performance detection of the special material for flame-retardant cables made by the above embodiments is as follows:

[0032]

[0033] It can be seen from the above table that the flame-retardant cable special material prepared by the present invention has high tensile strength and good flame-retardant performance.

Abstract

The invention belongs to the technical field of flame-retardant cable materials, and specifically, relates to a cable special-purpose material with a flame retardation effect and a preparation method thereof. The cable special-purpose material with a flame retardation effect comprises: be weight, 40 to 60 parts of a base resin, 20 to 30 parts of a fire retardant, 0.1 to 0.5 parts of at least one anti-oxidant, 5 to 10 parts of at least one dispersant, 0.5 to 5 parts of at least one coupling agent and 0.1 to 0.5 parts of a lubricating agent. The fire retardant is a mixture of microencapsulated red phosphorus, aluminum hydroxide and magnesium hydroxide, wherein particle sizes of aluminum hydroxide and magnesium hydroxide are above -10000 meshes. The cable special-purpose material with a flame retardation effect has good flame-retardant effects and excellent processing performances and mechanical performances.

Description

Technical field: [0001] The invention belongs to the technical field of flame retardant cable materials, and in particular relates to a cable flame retardant material for preventing cable flame delay. Background technique: [0002] The flame retardancy of wires and cables has always been a common concern in various countries. Cables are generally installed and laid in bundles or in multiples, and the insulation and sheath of cables are mostly composed of flammable polymers. Therefore, once it burns, due to the interaction between the cables, the flame will spread and the fire will expand rapidly, causing huge losses to people's lives and property. [0003] The current cable waterproof technology can be roughly divided into two categories. One is to take fire prevention measures for ordinary cables, for example, apply waterproof coating to ordinary cables, and fill fireproof materials in the through holes of cable ducts. The other type is dedicated to the flame retardant of...
