Abstract

The invention discloses a high-viscosity yellowing-resistant explosion-proof film adhesive. The explosion-proof film adhesive comprises the following components in parts by weight: 100 parts of acrylic acid adhesive, 5-10 parts of tackifying resin, 0.15-0.6 part of a curing agent and 50-90 parts of a solvent, wherein the acrylic acid adhesive is prepared by reacting the following components in parts by weight: 26-30 parts of isooctyl acrylate, 3-5 parts of acrylic acid, 0.5-1 part of hydroxyethyl acrylate, 5-10 parts of methyl acrylate, 53-65 parts of ethyl acetate and 0.5-1 part of azobisisobutyronitrile; the solvent is one or more selected from ethyl acetate, toluene and butanone; and the tackifying resin is hydrogenated resin. The invention also provides a high-viscosity yellowing-resistant adhesive tape prepared from the adhesive. The high-viscosity yellowing-resistant explosion-proof film adhesive has colorless transparent appearance, and can still ensure sufficient peeling forceaccording to different coating thicknesses. Under the condition of high-temperature aging, the explosion-proof film adhesive is not yellowing in appearance, and peeling force is basically not attenuated.

Description

technical field

[0001] The invention relates to the technical field of glue, in particular to a high-viscosity anti-yellowing explosion-proof film glue, an adhesive tape and a preparation method thereof. Background technique

[0002] With the development of technology, the scope and usage of display screens are increasing; because the outer glass of the display screen is prone to scratches after long-term use, and the glass is easily broken by external forces, which poses hidden dangers to the safety of users, so it is necessary to An explosion-proof film used for screen protection, and the acrylic resin used for bonding is an important part of the explosion-proof film. Generally, to achieve high viscosity, some resin will be added to the acrylic resin, so that the appearance is not colorless and transparent, and the yellowing effect of high temperature resistance is poor. Therefore, be badly in need of a kind of high-viscosity anti-yellowing anti-explosion membrane glue. ...
