Abstract
A thermal shrinkable tube which is coated with adhesive at the inner side is prepared with the following mode: using extruding machine to extrude the thermal shrinkable tube component; using irradiation machine to crosslink the tube component; expanding the crosslinked tube component to a preset diameter; and coating adhesive on the inner surface of the expanded tube component with a spiral mode. The tube component reduces the loss generated by the dual extrusion or the possibility of eccentric irradiation or eccentric expansion in the irradiation or expansion period thereby preventing the quality degradation. Besides, the adhesive can be coated at anytime when the thermal shrinkable tube is expanded. Therefore the species or thickness of the adhesive can be easily changed.

Description
Technical field
The present invention relates to a kind of adhesive coating device, and the method for the heat-shrinkable pipe of a kind of manufacturing of using this equipment.
Background technology
By utilizing the memory effect of cross-linked polymer, under the situation to heat-shrinkable pipe heating, heat-shrinkable pipe can be contracted to the diameter before expanding.The heat-shrinkable pipe of this class is generally used for protecting the coupling part of cable, and heat-shrinkable pipe more is widely used for various industries at present, especially in the boats and ships industry.
The heat-shrinkable pipe that boats and ships are used is used to transmit the coupling part of the cable of a large amount of electricity, as panel or busbar (bus bar).Especially, because the specific environment of boats and ships is coated with adhesive in the heat-shrinkable pipe that boats and ships are used.So that be coated with the heat-shrinkable pipe of adhesive when shrinking, coated adhesive at high temperature melts and around cable seal (seal) when heating.Because the cable that boats and ships are used at sea uses, so the protection cable segment connector is not subjected to the influence of environment, particularly seawater extremely important.Therefore, in the heat-shrinkable pipe that boats and ships are used, adhesive is extremely important.
In heat-shrinkable pipe traditional, that boats and ships are used, use by extruder and two complex extruders (duplex extruder) of forming as the adhesive extruder of secondary extruder and come extruding pipe.According to the method, produce the pipe component that the inboard scribbles adhesive, and this pipe fitting is passed cooling bay to be cooled to room temperature, then pipe component is furled around spool.
Hereinafter, detailed description is used to make the method for traditional, heat-shrinkable pipe.
Fig. 1 a is the schematic diagram that extruder used in traditional heat-shrinkable pipe manufacturer process is shown, and Fig. 1 b is the cutaway view that the two-tube member (duplex tube) that utilizes this method to extrude is shown.
Referring to Fig. 1 a and Fig. 1 b, traditional extruder comprises pipe extruder 11 and is positioned at the adhesive extruder 12 at extrusion machine head 13 places.Polyethylene and adhesive are supplied to pipe extruder 11 and adhesive extruder 12 respectively, and dual the extruding by extrusion machine head 13 forms two-tube member 100 subsequently.Two-tube member 100 passes cooling bay 14 and is cooled, and is furled around spool 15 then.At this, two-tube member 100 is arranged in its inboard application of adhesive 102.
Make the two-tube member that furls around spool advance to irradiation process, utilization makes pipe and adhesive crosslinked by the electron beam of the electron-beam accelerator generation of irradiator.
In irradiation process, shine β (beta) ray so that pipe component is crosslinked to two-tube member.At this moment, because the thickness of pipe component is less, the β ray can pass pipe better.Yet the β ray may not can pass the two-tube member that is coated with adhesive, even and the β ray pass pipe component, but because the thickness of this pipe is bigger, the β ray can't shine equably.Especially, adhesive shows the twice that absorptivity is a pipe, therefore compares with the single tube member that does not have any adhesive, and it has difficulties aspect uniform irradiation.If two-tube member can not be shone equably in irradiation process, then the degree of cross linking radially will change, thereby two-tube member just can not expand with homogeneous thickness during expansion process.
That is to say, irregular when crosslinked when in irradiation process, causing owing to irradiation is inhomogeneous, when heat that pipe is accepted to be used to expand during expansion process, the part that the degree of cross linking is low expands earlier and quickens sometimes and expands, and causes pipe itself to tear or serious eccentric and cause with low quality thus.
The cross section of crosslinked two-tube member is identical with the cross sectional shape of the two-tube member of extruding, but its chemical constitution changes owing to electron beam irradiation, thereby makes this cross section become the adhesive crosslinked with cross-linking tube.Crosslinked two-tube member is furled around spool, is used for expansion process subsequently.
Carry out two-tube member expansion process, crosslinked and be heated to temperature enough, that be used to expand, thus the two-tube member that is made into to expand.The two-tube member of this expansion becomes a kind of so heat-shrinkable pipe, promptly the thickness of this heat-shrinkable pipe for the thickness of the inner crosslinked dual pipe that is coated with adhesive half or 1/3.
Simultaneously, use, importantly make heat-shrinkable tube swelling to certain thickness for convenient.For this purpose, it is highly important that the pipe of extruding the thickness that radially has rule.If Guan Wei is extruded into constant thickness, just can not guarantees uniform irradiation in irradiation process, thereby cause eccentric expansion.
Therefore, during extrusion, the workman should make pipe have homogeneous thickness, produces waste material simultaneously within a certain period of time.In the prior art, utilize dual extruding to extrude two layers that are made of pipe and adhesive, the workman should be fixed as homogeneous thickness with exterior tube (be preferably by polyethylene or EVA and make), and the adhesive with inside is a homogeneous thickness then.In this course, and a layer is fixed as uniform thickness compares, produce the waste material of twice, therefore cause very big cost allowance.
In addition, because the thickness of fixing two layers than the thickness difficulty of fixing a layer, is extruded so off-centre can take place during extrusion.This off-centre is extruded and is caused eccentric expansion, thereby makes quality degradation.
In addition, the thickness of two-tube member that has adhesive is big greater than the thickness of the single tube member that does not have adhesive, and therefore two-tube member can produce more substandard products (inferiority).This is because bigger thickness has increased the possibility of differential expansion, rather than evenly expands.This type of differential expansion causes tearing of pipe, produces substandard products thus.
