This is equivalent to that, the substrate double-sided adhesive is prepared by coating glue on both sides of a substrate, so that the fluidity of the glue is weak, and thus if the substrate double-sided adhesive is placed for a long time in the manufacturing process, the viscosity of the double-sided adhesive is reduced, and finally the product is degummed and fried, and in order to thoroughly solve the problems, the inventor proposes the following specific scheme:
the utility model provides a prevent blown-out's sponge rubber for parcel wire rod, this sponge rubber is including the release film, no substrate double faced adhesive tape and the PU sponge of laminating in proper order.
Furthermore, the sponge glue also comprises a first glue area and a second glue area which are separately arranged.
Further, the width a of the first glue area is 1.5-2.5 times of the diameter d of the wire.
Furthermore, the width b of the second glue area is 5-10 times of the diameter d of the wire.
Further, first gluey district and second glue and be equipped with middle gluey district between the district, should glue the district and only include no substrate double faced adhesive tape and PU sponge in the middle of, when the parcel wire rod, should glue the district and the wire rod laminating in the middle.
Further, the width c of the middle glue area is 1-1.5 times of the diameter d of the wire.
Further, first gluey district one side still be equipped with the first handle district that conveniently tears, this first handle district only includes from the type membrane.
In the present invention, the first glue area is identified as the area that does not contain the first handle area.
Further, the length E of the first handle area is 5-15% of the length A of the first glue area.
Further, the second glue district one side still be equipped with the second handle district that conveniently tears, this second handle district only includes from the type membrane.
In the present invention, the second glue region is identified as the region that does not contain the second handle region.
Further, the length F of the second handle area is 5-15% of the length B of the second glue area.
Furthermore, the double-sided adhesive tape without the base material only comprises two parts, namely an adhesive and release paper.
In the invention, the double-sided adhesive tape without base material is a roll-shaped or sheet-shaped adhesive tape prepared by coating an adhesive such as an elastomer pressure-sensitive adhesive, a resin pressure-sensitive adhesive or an acrylic pressure-sensitive adhesive on a release paper material. The non-substrate double-sided adhesive is formed by coating glue on release type isolation paper, so that the glue is high in flowability, the pasting area of the non-substrate double-sided adhesive is larger than that of the substrate double-sided adhesive, and the glue can be better pasted on PU sponge when the non-substrate double-sided adhesive is pasted.
A method for manufacturing the cotton-wrapped wire by using the sponge rubber comprises the following steps:
(1) Placing the wire on the middle glue area;
(2) Tearing off the release films on the first handle area and the first glue area, and wrapping the first glue area outside the wire rod;
(3) And tearing off the release films on the second handle area and the second adhesive area, and wrapping the second adhesive area to obtain the cotton-wrapped wire.
Compared with the prior art, the invention has the following advantages:
(1) In the invention, through a plurality of tests and repeated research and thinking, the root cause of the cotton soaking and frying in the prior art is mastered, and a solid foundation is laid for later-stage improvement;
(2) The invention changes the bad condition of cotton soaking and opening, thereby improving the product quantity and reducing the cost of manual later repair
