Problems solved by technology

In aerospace, transportation, medical and industrial equipment, automobile, home appliance, and electronic market industries, it can be used for bonding nameplates and labels; at present, in the industry, for the protection of external walls, kraft paper is often used as the outer layer Yes, the kraft paper has a protective effect on the EVA foam, but in the prior art, it is difficult to stick firmly between the kraft paper and the EVA foam, and it is easy to separate. For example, the patent CN105542062A discloses a new type of acrylate glue and its preparation method. The glue is reacted by adding acrylate monomer, acrylic acid and initiator into a low-temperature and normal-pressure reactor. Although the glue prepared by this method can be used to make foam tapes, it is not enough for kraft paper and EVA.

Abstract

The invention discloses a bonding agent of an adhesive tape for external wall protection and a processing process thereof. The bonding agent is prepared from the following raw materials in parts by weight: 0.5 to 0.85 part of initiators, 260 to 320 parts of mixing monomers, 220 to 260 parts of solvents, 90 to 105 parts of tackifiers and 3.5 to 5.5 parts of ethyl alcohol, wherein the mixing monomers are prepared from butyl acrylate, 2-ethylhexyl acrylate, acrylic acid, hydroxyethyl methylacrylate and vinyl acetate; the bonding agent is used between EVA foam cotton and kraft paper, so that the kraft paper and the EVA foam cotton are firmly pasted, so that the kraft paper and the EVA foam cotton are tightly attached without delamination; a good protection effect is achieved.
