Abstract

The invention discloses a waterproof acrylic acid adhesive tape and a preparation method thereof. The waterproof acrylic acid adhesive tape comprises a substrate layer, waterproof acrylic acid adhesive is applied to the substrate layer to form an adhesive layer, and the other surface of the adhesive layer is adhered to a release material layer. The waterproof acrylic acid adhesive tape is prepared from components A in parts by weight, and the components A comprises paraffin, a silane coupling agent, methyl ethyl ketone, isocyanate, methyl methacrylate, ethyl acrylate and dimethyldiethoxylsilane. Due to the formation of a network structure, the distance among latex particles can be shortened greatly, the gaps among latex particles can be narrowed, water molecules can be hereby prevented from entering the acrylic acid adhesive, and the purposes of improving the cohesion and the water resistance of an adhesive film can be achieved. In addition, because paraffin is mixed into a solution by stirring, and paraffin molecules fill in the gaps among latex particles, water molecules can be prevented from entering the acrylic acid adhesive. Moreover, paraffin can form a waterproof protective film on the surface, thus water is prevented from entering the acrylic acid adhesive.

Description

technical field [0001] The invention relates to the technical field of acrylic tapes, in particular to a waterproof acrylic tape and a manufacturing process thereof. Background technique [0002] Acrylates are widely used as adhesives because of the strong hydrogen bonding of the ester group, and its types include cyanoacrylate adhesives and reactive acrylic adhesives. Adhesives that use polyacrylate as a single-component or main component are thermoplastic and thermosetting. The single-component adhesive has no solvent, can be cured at room temperature, and has certain transparency. There are mainly a-cyanoacrylate adhesives and acrylic adhesives. Acrylic adhesives are used to stick one object to another. People pay more attention to the visual requirements of various furniture or electronic products such as styles and colors, so the appearance of electronic products is particularly important. This requires higher and higher requirements for adhesive tapes, which often re...
