Problems solved by technology
However, when heat-shrinkable tubes are used for anti-corrosion or insulation purposes, it will be found that it is not that the radiation quality of the heat-shrinkable tubes is not good or the specifications used are wrong, but that the adhesion of the heat-shrinkable tubes is not enough to affect the sealing. Accidents due to poor sealing effect of heat shrinkable tubes

Embodiment Construction
[0008] The technical scheme of the preparation method of the inner wall glued heat-shrinkable tube is: transform the structure of the heat-shrinkable tube into the splitter cone part, in the original process structure, add a separate adhesive to the process hole 7 and the adhesive delivery channel 6, so that the forming The outlet of the splitter cone directly follows the heat-shrinkable tube to produce a layer of annular adhesive film 10 attached to the inner wall of the heat-shrinkable tube.
[0009] According to the arrow, the raw material of the heat-shrinkable tube enters the raw material channel 4 of the heat-shrinkable tube through the raw material inlet 8 of the heat-shrinkable tube. Heat-shrinkable tube semi-finished product 1; the adhesive raw material is sent to the adhesive adding process hole 7 as indicated by the arrow, and passes through the adhesive conveying channel 6, the raw material distribution seat 5, the distribution cone core 13, the adhesive distributio...

Abstract
The invention relates to a method for preparing a heat shrinkable tube having the inner wall coated with glue, which is to coat a layer of glue film on the inner wall of the heat shrinkable tube. By modifying the structure of a molded spure spreader part in heat shrinkable tube production equipment and by adding an adhesive filling hole and a special delivery channel, a layer of annular glue film adhered to the inner wall of the heat shrinkable tube is generated at the outlet of the molded spure spreader part directly along with the heat shrinkable tube. The method has the advantages that: when the heat shrinkable tube having the inner wall coated with the glue is used in an environment for anticorrosion or insulation, due to the layer of annular glue film adhered to the inner wall of the heat shrinkable tube, the defects of poor adhesion and sealing of the heat shrinkable tube are overcome, the anticorrosion or insulation grade of the heat shrinkable tube is improved, and the application field of the heat shrinkable tube product is widened.
Description
【Technical field】 [0001] The patent of the present invention relates to a preparation method for coating a layer of adhesive film on the inner wall of a heat-shrinkable tube, which belongs to the field of processing and preparation of radiation cross-linked polyethylene and similar materials. 【Background technique】 [0002] The use of heat shrinkable tubes has been widely used in various products through the effective development of human beings. For example, applying heat shrinkable tubes to wire joints can ensure the insulation of the handle, heat shrinkable tubes for handles of sports equipment can improve the feel and non-slip, and bright heat shrinkable tubes can increase everyone's attention and ease of use in more eye-catching places. The heat-shrinkable tube on the outer wall of the tube and rod material of the corroded object can achieve the purpose of anti-corrosion and other advantages. However, when heat-shrinkable tubes are used for anti-corrosion or insulation...
