Problems solved by technology

[0003] However, the production process in the prior art uses the existing base glue and surface glue, which itself has the defect of airtightness, and there are no measures to ensure air permeability in the design and molding process
When grinding, it is only at the edge bonding, which causes the existing adhesive tape to have the defect of airtightness. In view of this, the inventor proposes a breathable and waterproof composite adhesive tape and its preparation method

Abstract

The invention discloses a breathable waterproof composite adhesive tape and a preparation method thereof, and particularly relates to the field of adhesive products, wherein the breathable waterproof composite adhesive tape comprises a waterproof breathable layer; a self-adhesive layer is arranged below the waterproof breathable layer, a non-woven fabric layer, a bonding coating layer and a silica gel layer are sequentially stacked on the transparent adhesive layer, the bonding coating layer covers the surface of the waterproof breathable layer, and a non-woven fabric layer is impregnated in the bonding coating layer; and the self-adhesive layer is formed by coating conventional self-adhesive non-setting adhesive paste, the thickness of the bonding coating layer is 0.1-0.2 mm, and an accelerant TT can be equivalently replaced by any one of an accelerant CZ, an accelerant DOTGM and an accelerant DOTG. According to the breathable waterproof composite adhesive tape and the preparation method thereof, sisal hemp powder and straw powder are added, so that the composite adhesive can be fluffy and achieve breathable and waterproof effects; and meanwhile, the adhesive surface is completely polished, so that the adhesive tape is better in breathability and has excellent comprehensive performance, and the service life can be remarkably prolonged.

Description

technical field [0001] The invention relates to the field of adhesive products, in particular to a breathable and waterproof composite adhesive tape and a preparation method thereof. Background technique [0002] Adhesive tape, also known as adhesive tape, tape and tape paper, etc., is a strip-shaped sticky artifact that can be adhered to the surface of some items and can be used to connect two different items or to protect some kind of screen wall. The adhesive tape is composed of two parts, the substrate and the adhesive, and two or more unconnected objects are connected together by bonding. Its surface is coated with a layer of adhesives. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives, but in modern times various polymers are widely used. Adhesives can stick things because A bond is formed between the molecule itself and the molecule of the object to be connected. This bond can firmly bond the mo...
