AI Technical Summary

Problems solved by technology

[0003] However, most of the temperature-indicating paints of the existing heat-shrinkable tubes use traditional manual techniques such as spraying, dusting, and shaking. Manual spraying is very easy to cause waste of temperature-indicating paints in production, pollute the workshop environment, spray spots of uneven size, and poor product appearance quality.

Embodiment 1

[0069] Example 1: Temperature-indicating fuel oil-resistant heat-shrinkable double-walled pipe, including an outer wall heat-shrinkable tube layer, an inner wall spiral hot-melt adhesive layer, the hot-melt adhesive is a modified oil-resistant hot-melt adhesive, and the outer wall surface is provided with a temperature indicating paint ;

[0070] The temperature-indicating paint contains 85 parts by weight of color-changing pigments; 130 parts by weight of polymer base materials; 180 parts by weight of phase stabilizers; 700 parts by weight of emulsifiers; 150 parts by weight of fillers; 4500 parts by weight of solvents .

[0071] The color changing pigment is selected from basic copper carbonate.

[0072] The polymer base material is selected from ethyl cellulose and polyvinyl acetate.

[0073] The phase stabilizer is selected from polyisobutylene with a molecular weight of 40,000-85,000 and is purchased from BASF.

[0074] The emulsifier is selected from sorbitan monooleate Span80. ...

Embodiment 2

[0099] Example 2: The difference from Example 1 is that the color-changing pigment of the temperature indicating paint is selected from copper sulfate pentahydrate.

Embodiment 3

[0100] Example 3: The difference from Example 1 is that the filler of the temperature indicating paint is selected from calcium carbonate.

Abstract

The invention discloses a temperature indicating type fuel oil thermal shrinkage resisting double-wall pipe for a protective thermal shrinkage sealing cap type optical cable connector box. The pipe structurally comprises outer wall surface temperature indicating paint, an outer wall heat shrinkable pipe layer, an inner wall spiral hot-melt glue layer and an outer wall pipe opening with one reserved end. The invention discloses the temperature indicating type fuel oil thermal shrinkage resisting double-wall pipe for the protective thermal shrinkage sealing cap type optical cable connector box,the pipe can be used for protecting the cap type optical cable connector box from passing through a cycle of -40 DEG C to 65 DEG C high and low temperature for 10 times, but also from passing through7-day sealing test for resisting diesel oil, kerosene, and 70% of gasoline + and 30% of xylol; due to superior sealing performance of the pipe, the cap type optical cable connector box can not be subjected to phenomena of looseness, shedding and air leakage when eroded by fuel oil, to finally ensure that the thermal shrinkage sealing cap type optical cable connector box can withstand severe climate changes and harsh working environments in overhead laying, pipeline laying, and direct burial laying.

Description

Technical field [0001] The invention relates to a temperature-indicating fuel oil-resistant heat-shrinkable double-wall pipe, a preparation method thereof, and a cap-type optical cable joint box in the form of protective heat-shrinkable sealing, belonging to the technical field of cap-type optical cable joint box protective sealing in the form of heat-shrinkable sealing . Background technique [0002] In the 1980s, China began to build optical fiber cable networks. With the construction of 4G mobile communication networks and optical fiber cables to the home, my country has built the world’s largest optical cable network as an optical cable connector box industry for the protection of splicing and divergent nodes in the optical cable network. Also from scratch. The optical cable connector box is mainly used for the splicing and divergence of optical cables in the optical cable network. It is suitable for the protection of various optical cable straight-through and branch joints. ...
