Problems solved by technology

The main reason is that fluorescent tubes generate heat for a long time, and ordinary heat-shrinkable tubes are difficult to meet the requirements of high temperature resistance and excellent transparency.
In addition, the luminous powder has a relatively large proportion. If it is processed with plastics, if it is excessively cut, it will cause the luminous powder to become dark and black, which will seriously affect the luminous effect; at the same time, the light transmittance of the transparent heat shrinkable tube will also be affected.
Therefore, the amount of luminous powder added to some existing self-luminous heat-shrinkable tubes is small, because once a large amount of luminous powder is added to the formula, there will be serious problems in the manufacturing process of the heat-shrinkable tube, such as granulation and extrusion. Excessive shearing effect, but the amount of luminous powder added is small, and the luminous effect cannot reach the basic lighting effect when the power is off

Abstract

The invention discloses a long-afterglow photo-induced light-storing heat-shrink tube and a preparation method thereof. According to the invention, surlyn resin, an aluminate-type light-storing luminescent pigment, a silicone masterbatch, an antioxidant, a light stabilizer, a lubricant, and the like are adopted as raw materials. Through the processes of mixing, granulating, extrusion molding, radiation cross-linking, expansion shaping, and the like, the heat-shrink tube is prepared. The long-afterglow photo-induced light-storing heat-shrink tube provided by the invention is mainly used for shrinking outside a fluorescent lamp tube. For example, a fluorescent lamp with the long-afterglow photo-induced light-storing heat-shrink tube is arranged after every 3 to 5 fluorescent lamps. When power failure occurs, in every 8 to 10 meters, one long-luminescence fluorescent lamp which can continue providing light is arranged, such that personnel in a working site can evacuate safely and orderly.

Description

technical field [0001] The invention relates to a thermoplastic tube material, in particular to a long-afterglow light-induced light-storage type heat-shrinkable tube and a preparation method thereof. Background technique [0002] Since the 1960s, various heat-shrinkable tubes have been developed at home and abroad. The production process generally includes mixing, extrusion, radiation cross-linking and expansion. The heat-shrinkable tube has excellent mechanical properties, insulation properties, and It is heat-resistant, corrosion-resistant and easy to use, and is widely used in the connection protection of wires and cables, and the corrosion protection of pipe welds. In recent years, with the vigorous development of the heat-shrinkable material industry, heat-shrinkable products have also been given a new market position. It has been reported that heat-shrinkable materials are added with luminous materials, and attempts are made to make self-luminous heat-shrinkable tubes...
