Embodiment

[0035] Two groups of formulas in Table 1 are prepared according to parts by weight. Add the flame retardant, smoke suppressant, ceramic powder A, ceramic powder B, adhesive, lubricant, coupling agent, antistatic agent, release agent, and thickener into the high-mixer in sequence, and the high-mixer 10-15 minutes. The mixture is then extruded in a single-screw granulator.

[0036] The main performance test of the embodiment formula is shown in Table 2.

Abstract

The invention relates to a preparation method of a high-temperature-resistant ablation-resistant ceramic mineral filled oxygen-isolating material for a cable, wherein the high-temperature-resistant ablation-resistant ceramic mineral filled oxygen-isolating material for the cable comprises a flame retardant, a smoke suppressant, ceramic powder A, ceramic powder B, a binder, a coupling agent, a lubricant, an antistatic agent, a demolding agent and a thickener. According to the invention, the preparation process is simple and easy to operate, wherein the raw materials are highly and uniformly mixed, the binder is added according to a certain proportion, mixing is performed, and surface extrusion is performed by using a single-screw extrusion process; and the high-temperature-resistant ablation-resistant ceramic mineral filled oxygen-isolating material is mainly used for a medium-low voltage cable filling layer, is excellent in flame-retardant effect, low in smoke density and high in curing strength, can form a compact ceramic product in a high-temperature environment, and can effectively protect the internal structure of a cable.

Description

technical field [0001] The invention relates to a high-temperature-resistant and ablation-resistant ceramic mineral-filled oxygen barrier material for cables and a preparation method thereof. Background technique [0002] In recent years, several domestic large-scale public entertainment venues, chemical industry, coal mines, and commercial building fires have caused heavy losses of people's lives and property, and people have a deeper understanding of fire protection and fire safety. At present, the fire prevention and fire resistance measures required by my country's wire and cable design regulations are only passive fire protection after the wire and cable catch fire. To prevent wire and cable fires, we must start from the control of risk factors, and use relevant standards to take corresponding fire prevention measures. There are more and more reports about ceramic fire-proof and refractory polyolefin and silicone rubber, but it has higher requirements for equipment and...
