Double-sided adhesive tape

Abstract

The invention provides a double-sided adhesive tape, and solves the problem of infirm connection of existing double-sided adhesive tapes and a surface layer. The double-sided adhesive tape comprises a long strip base layer, the upper side and lower side of the base layer are respectively adhered with an adhesive coated layer 1 and an adhesive coated layer 2, a long strip surface layer is adhered to the adhesive coated layer 1 and is arranged along the length direction of the base layer, the upper side face of the surface layer is equipped with several through-holes that are evenly distributed along the length direction of the surface layer, each through-hole is internally inserted with cylindrical colloidal particles, the upper end faces of the colloidal particles are flush with the upper side wall of the surface layer, and the lower ends of the colloidal particles have butt parts adhering to the adhesive coated layer 1, the upper side of the surface layer is provided with a long strip seal layer, the seal layer is arranged along the length direction of the surface layer, and has a cross sectional area equal to that of the surface layer, the upper end faces of the colloidal particles are adhered to the lower side face of the seal layer, and the viscosity of the colloidal particles is smaller than that of the adhesive coated layer 1. The double-sided adhesive tape has the advantage of firm connection with the surface layer.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a double-sided adhesive tape. Background technique [0002] At present, in the field of construction and decoration, more and more double-sided tapes are used for the pasting of facing materials, and compared with the traditional all-purpose glue spraying or brushing, it makes the construction process cleaner and faster. However, there is also a problem in the construction process of double-sided adhesive tape, which is mainly manifested in the instant bonding performance of double-sided adhesive tape. If you do not pay attention, the pasting position of the decorative material will be inaccurate, and it will be difficult to move. Repeated pasting will damage the finish. layer surface structure. [0003] For the above-mentioned problems, people have realized the deficiencies and made improvements, such as a double-sided adhesive tape [application number: 201410379596.0; application publicatio...

AI Technical Summary

Problems solved by technology

But there is a problem in this double-sided adhesive tape: when the surface layer is adhered to the first glued layer, the surface layer is always subjected to the active force exerted by the protrusion, and this force makes the surface layer have the ability to separate from the first glued layer. trend, thus reducing the reliability of the adhesion between the first glue layer and the surface layer
