Abstract

The invention discloses a novel environmentally-friendly cable splice closure sealant and a preparation method thereof, and belongs to the technical field of preparation of sealants. The sealant comprises silicone rubber, a flame retardant, butyl rubber, medium molecular weight polyisobutylene, low molecular weight polyisobutylene and an antioxidant. The preparation method comprises the followingsteps: S1, weighing: weighing the raw materials for later use; S2, kneading: adding and kneading the raw materials; S3, blending: blending the obtained kneaded rubber compound; and S4, extruding: extruding the blended rubber compound, and cooling and cutting the extruded rubber compound to obtain the novel environmentally-friendly sealant. The sealant of the invention has excellent adhesion, flameretardancy, filling property, sealing property, water resistance, high and low temperature resistance, acid resistance, alkali resistance, salt resistance and dielectric property; preparation materials of the sealant do not contain solvents or halogens, so the sealant is environmentally friendly; and the preparation method has the characteristics of simple production process, time saving and energy saving, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of sealant preparation, and in particular relates to a novel environmental-friendly sealant for optical cable joint boxes and a preparation method thereof. Background technique [0002] With the rapid development of my country's industrialization in recent years, the business demand for communication systems, monitoring, and control has increased rapidly, and the use of optical fiber cables instead of copper cables as a means of information transmission has gradually shown huge technical potential. But at the same time, with the frequent occurrence of various accidents and disasters, optical cables and cables often play the role of fuse, causing the fire to spread rapidly and damage valuable electronic instruments and equipment, affecting the normal operation of the entire line or even paralyzing. Thereby expanding the loss of the disaster. [0003] In communication cable and optical cable joint equipment, ...
