Description

TECHNICAL FIELD

[0001] The application relates to the technical field of double-sided adhesive tape equipment, in particular to an anti-weathering type foam double-sided adhesive tape. BACKGROUND

[0002] The adhesive tape is composed of a base material and an adhesive, and is used to connect two or more objects together through adhesion, and is one of the indispensable tools in our daily life. According to different use environments, the adhesive tape is divided into insulating adhesive tape, tensile adhesive tape, medical adhesive tape, waterproof adhesive tape and foam double-sided adhesive tape.

[0003] The existing foam double-sided adhesive tape generally has a foam base layer, and adhesive layers are arranged on the two sides of the foam base layer, and release paper is arranged on the adhesive layers. The two sides of the foam layer in the width direction are in a bare state, especially the foam double-sided adhesive tape is relatively thick, and the two sides of the foam layer in the width direction have a large bare area. When the double-sided adhesive tape is wound on a winding drum for storage, the foam on the two sides is directly exposed to the outside, the foam is a porous material and is easily eroded by external substances, so that the foam is easily weathered, the anti-aging effect is poor, the adhesion strength of the adhesive layer is affected, and the service life is reduced. Therefore, the application provides an anti-weathering type foam double-sided adhesive tape. CONTENT OF THE UTILITY MODEL

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0022] As Figures 1-4As shown, the anti-weathering type foam double-sided tape provided by one embodiment of the present application comprises: a foam strip 1, the outer surface of which is sleeved with a protective sleeve 2, the longitudinal section of the foam strip 1 and the protective sleeve 2 are both configured as a rectangle, recesses 3 are formed on the upper and lower sides of the protective sleeve 2, a plurality of through grooves 4 are formed in the inner wall of the recess 3, and adhesive layers 5 are arranged in the two recesses 3 and bonded with the foam strip 1. By forming the recesses 3 on the upper and lower sides of the protective sleeve 2 and forming the through grooves 4 in the inner wall of the recess 3, when the adhesive layers 5 are coated in the recesses 3, a complete adhesive tape can be formed, and the adhesive layers 5 are also bonded with the foam strip 1. The side of the two adhesive layers 5 away from the foam strip 1 is provided with release paper 6, which can cover the two adhesive layers 5 and the upper and lower sides of the foam strip 1. The protective sleeve 2 covers the left and right sides of the foam strip 1, so that the foam strip 1 is not directly exposed to the outside, reducing the erosion of external substances, thereby improving the anti-weathering and anti-aging performance and prolonging the service life.

[0023] As shown in Figure 3 and Figure 4 In some embodiments, a plurality of embedding grooves 7 are formed on the upper and lower sides of the foam strip 1, and a plurality of embedding blocks 8 are configured on the inner wall of the upper and lower sides of the protective sleeve 2. The embedding blocks 8 on the two sides are respectively embedded and matched with the embedding grooves 7 on the two sides. By embedding and matching the embedding grooves 7 and the embedding blocks 8, the connection strength of the protective sleeve 2 and the foam strip 1 is improved, so that the foam strip 1 is not easy to be pulled out of the protective sleeve 2, thereby prolonging the service life.

[0024] As shown in Figure 4 In some embodiments, the foam strip 1 is made of glass wool. The glass wool is a material formed by fiberizing molten glass into a cotton-like material. It is corrosion-resistant, chemically stable, and has good fireproof effect, thereby prolonging the service life of the double-sided tape.

[0025] As shown in Figure 4 In some embodiments, a plurality of positioning convex strips 9 are arranged on the side of the adhesive layer 5 close to the release paper 6. Preferably, the positioning convex strips 9 are made of silicone material. When the double-sided tape is pasted, the release paper 6 is first torn off, and the adhesive tape is placed on the bonding surface. The positioning convex strips 9 first come into contact with the surface, at which time the adhesive layer 5 has not yet been bonded with the surface. At this time, the position of the adhesive tape can be adjusted appropriately. After the position of the adhesive tape is adjusted, the adhesive tape is pressed again. The material of the positioning convex strips 9 can be deformed, so that the adhesive layer 5 is bonded with the surface. This avoids the need to tear and reapply the adhesive tape due to placement errors during the pasting process, thereby ensuring the bonding strength of the adhesive tape and avoiding waste of the adhesive tape, thereby improving the practicality.

[0026] As shown in Figure 1As shown in the drawings, in some embodiments, the width of the release paper 6 is wider than the adhesive layer 5 and flush with the width of the protective sleeve 2. When the release paper 6 is not torn, the release paper 6 can cover the gap between the adhesive layer 5 and the groove 3. When the adhesive tape is wound on the reel as a whole, the layers of the adhesive tape are pressed against each other, so that the release paper 6 effectively seals the gap between the adhesive layer 5 and the groove 3, thereby effectively preventing external substances from eroding and ensuring the adhesion of the adhesive layer 5, thereby prolonging the service life.

[0027] As shown in the drawings, Figure 1 and Figure 4 As shown in the drawings, in some embodiments, the side of the release paper 6 away from the adhesive layer 5 is arrayed with a plurality of anti-slip ridges 10. By arraying the anti-slip ridges 10 on the surface of the release paper 6, the frictional resistance of the fingers against the surface of the release paper 6 is increased, and the anti-slip ridges 10 can also be used as a leverage point for tearing the release paper 6, making it more convenient and fast to tear the release paper 6.

[0028] As shown in the drawings, Figure 3 In some embodiments, the protective sleeve 2 is made of polyurethane. Polyurethane, the full name of which is polyurethane, is a high polymer material formed by polyol and polyisocyanate through condensation polymerization and has excellent mechanical properties. This material not only effectively prevents moisture from penetrating and avoids the erosion and damage of the foam strip 1 by water, but also has good elasticity, which facilitates elastic deformation and adhesion with the foam strip 1. In addition, the material has good acid and alkali resistance and is not eroded by pollutants, thereby improving the weather resistance and anti-aging performance of the adhesive tape and prolonging its service life.

[0029] As shown in the drawings, Figure 4 In some embodiments, the adhesive layer 5 is made of acrylic pressure-sensitive adhesive. Acrylic pressure-sensitive adhesive is a self-adhesive substance that can form a relatively firm adhesive force under a small force. It is a kind of adhesive that can be tightly bonded to the adherend by applying light pressure without the aid of solvents, heat or other means, thereby improving the adhesive strength of the adhesive tape.

[0030] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
