Abstract
Fabric (10) with HDPE shrinkable fibres (12) in wraparound direction laminated to LDPE film (14) on outside and coated with adhesive (16) on inside curls around small diameter object such as wire splice to resist unwrapping during heat shrinking and thus provides side-entry splice (SES) especially suitable for automotive wiring assembly.
Description
The invention relates to heat-shrinkable article, above-mentioned heat-shrinkable article is used to hold diameter and reaches 25 millimeters article.Above-mentioned object for, such as, among automative wiring harness, prevent that the pollution of environment butted line joint is particularly useful.
The heat-shrink tube of being made by plastic material was used to such purpose existing many years, and the shortcoming that such pipe has is that they must be put from a free end of electric wire, and this may be inconvenient in practice sometimes.Since tighten up around the edge of the thermal contractible plastic thin slice of waiting to hold article former be difficult, so in the past with such thin slice hold minor diameter article trial commercial be infeasible.The sort of pincers clamp device that is widely known by the people that is used for the formula that the holds closure of big cable is unpractical at undersized wiring joint.The trial of using bonding agent to tighten up above-mentioned thin slice also is easy to failure, because in the thermal contraction process, above-mentioned thin slice is easy to unclamp from its article that hold.
The approach that the invention provides cleverly a kind of and low relatively expense is to alleviate these problems.
The invention provides a heat-shrinkable article, be used to hold a diameter and reach 25 millimeters article, above-mentioned object comprises:
(i) fabric, the pyrocondensation fiber that it contains hold direction at it and extend,
(ii) a flexible layer is made by crosslinked plastic material, and a main surface that is in turn laminated to above-mentioned fabrics upward also outwards deviates from the above-mentioned article that it holds.
(iii) hot activation bonding agent, another the main surface that is coated in fabric is with inwardly towards above-mentioned article.Above-mentioned object is so to construct, so that the recovery of the heat of the above-mentioned fabrics in using makes above-mentioned object hold above-mentioned article, and curls towards the surface with above-mentioned bonding agent, and activates above-mentioned bonding agent.
Fabric or with other intermediary layer that fabric directly contacts, can directly have (preferably being stained with) flexible layer (ii) with bonding agent (iii).
When being set, the pyrocondensation fabric make it become (in the use) internal layer of repeatedly pressing two composition thin slices of forming with crosslinked plastic material, the present invention thereby utilized the asymmetric convergent force that in thin slice, produces, asymmetric convergent force holds the direction contraction by pyrocondensation fiber edge and produces, with the above-mentioned object that in contraction, curls, the curling of this mode strengthened the effect of holding, and unclamps the trend that holds thereby offset in thermal contraction.A wonderful discovery is, connect after holding initially the tightening up an of object in the overlapping of responsive bonding agent according to object of the present invention by working pressure, object according to the present invention withstands heat and recovers test, the slip that connects that overlaps do not produce any unacceptable opening, although may surpass 50% of its initial overlapping width in such contraction.
Preferably, the pyrocondensation fiber of fabric only holds the direction extension along it basically.The dimensional stability to heating in house of above-mentioned object, promptly along the length that holds direction before pyrocondensation and the ratio of pyrocondensation after finishing, preferably within 1.10: 1 to 5: 1 scope, more preferably within 1.3: 1 to 3: 1, especially within 1.5: 1 to 2: 1.Above-mentioned object can be arranged to band or winding easily, promptly can be to be any form of 1 to 1000 meter holding length on the direction.Will be appreciated that on the basis that produces coiling, such winding or band can advantageously be supplied with the automation erection unit, or other are suitable for sealing the suitable equipment of less article such as wiring joint.As substituting, can be according to object of the present invention by form setting with pre-cut band or thin slice, above-mentioned band or thin slice have pressure sensitive adhesive at the one end regions at least, and pressure sensitive adhesive can tighten up the object that is holding article in the above-mentioned use before the thermal contraction of object.
Contain the various forms of fabrics of pyrocondensation fiber can be selected the pyrocondensation fiber is formed by high density polyethylene (HDPE) in a preferred form of the present invention to satisfy final instructions for use, preferably, polyethylene is crosslinked by shining.Be used to make the above-mentioned suitable material that repeatedly is pressed onto the plastic coat on the fabric and also can select by test, a kind of preferable material is a low density polyethylene (LDPE), and is preferably crosslinked by irradiation after being pressed towards fabric formation thin slice.Fabric can be before it repeatedly be pressed onto on the ductile bed exposure, but preferably after repeatedly pressing, apply before the bonding agent with the plastic tab exposure.
Any hot activation bonding agent all can be coated on the surface that deviates from sheets of plastic material of fabric, and preferred bonding agent is that heat is melted or heat cured bonding agent.Selected bonding agent all should satisfy the final instructions for use of above-mentioned object naturally.The material of above-mentioned object, size and structure all are carried out to be selected and contrast, to satisfy the final instructions for use of being discussed, for example, for the automative wiring joint, material, size and the selected so that above-mentioned object of structure are within 30 seconds, preferably within 20 seconds, more preferably within 10 to 15 seconds, the outer surface that acts on above-mentioned object by hot-air or infrared heating shrinks, and the temperature of above-mentioned outer surface is preferably between 250 ℃ to 270 ℃.The example of adhesion agent that may be suitable for above purpose is at WO-A-8707755 (RK310), GB-A2104800 (RK149), among EP-A-0157478 (RK232) and the common unsettled International Application PCT/GB95/00731 (B247) description is arranged all, all these are described all as with reference to being incorporated among this literary composition.
For being familiar with the personage of this area, make the method for fabric, preferably make, and the method for using sheets of plastic material and applied adhesives is known by weaving.
The above-mentioned fabrics part can be made as the fiber described in the GB-A-2134334 substantially by pyrocondensation fiber and other, but preferably omitted wherein second plastic tab and spraying plating Mylor lamella that metal is arranged.For example, above-mentioned fabrics can be used a plain cloth of being made up of pyrocondensation warp thread and weft yarn (last, down).Warp thread is crosslinked high density polyethylene (HDPE), diameter 0.2～0.3mm, 35.4 every centimetre (90 of per inch); Weft yarn is a glass fibre, 3 * 68g/km, or the PET ultimate fibre of 0.1mm (PET monofilament) (2 every latitudes), every centimetre of 3.9 latitude (10 latitude per inch).Weft yarn is by separated from one another, so that its unlikely big unacceptable degree that arrives of influence that warp thread is shunk.
Alternative Fabric Design is as shown in the table:
The structure of fabric
| Warp thread root/centimetre (root/inch) | Warp diameter or linear density and material | Weft yarn latitude/centimetre (latitude/inch) | Diameter of the weft yarn or linear density and material | The braiding scheme | |
