Abstract
The invention discloses an expansion-controllable fire-resistant sleeve and a production method thereof and belongs to the technical field of composite materials and preparation thereof. The preparation method of the expansion-controllable fire-resistant sleeve includes: preparing an adhesive layer on a bearing layer, and adhering expansion fire-resistant particles to the surface of the adhesive layer to obtain a single-layer or double-layer expansion-controllable fire-resistant belt; using an accessory structure to fix the single-layer or double-layer expansion-controllable fire-resistant belt to the outside of a rubber tube to obtain the single-layer or double-layer expansion-controllable fire-resistant sleeve. In a high-temperature environment, the expansion fire-resistant particles expand to bring a flame retardance and thermal insulation effect into play. The adhesive layer is mainly used for adhering in a normal-temperature or low-temperature environment and is softened and degraded in the high-temperature environment. The bearing layer is mainly used for bearing the expansion and fire-resistant particles in the normal-temperature or low-temperature environment and is degraded and carbonized in the high-temperature environment. The expansion-controllable fire-resistant sleeve has the advantages that the sleeve is applicable to high-pressure rubber tubes to greatly increase the thermal resistance of the rubber tubes and greatly prolong the service life of the rubber tubes, and the sleeve is good in reliability and well applicable to various high-temperature environments.
