Description

TECHNICAL FIELD

[0001] The utility model relates to composite back adhesive technical field, concretely relates to a composite back adhesive structure with environmental protection. BACKGROUND

[0002] The back adhesive is a thin film with viscosity, which is generally used after being adhered to a Mylar sheet in the use of electronic products.

[0003] For example, the Chinese patent with publication number CN219603507U proposes a composite back adhesive structure with anti-wrinkle structure. The assembly first supports high-viscosity back adhesive one and high-viscosity back adhesive two with rubber fixing belt one and rubber fixing belt two, respectively, so that the high-viscosity back adhesive one and high-viscosity back adhesive two are not prone to longitudinal overlap after being supported. Then, the high-viscosity back adhesive one and high-viscosity back adhesive two are supported with rubber support belt one and rubber support belt two, respectively, to further improve their lateral stability during use. Finally, the high-viscosity back adhesive one and high-viscosity back adhesive two are supported with a PET film layer, so that they are not prone to wrinkling after overlapping. Thus, the composite back adhesive has the advantage of preventing wrinkles during adhesion, and the anti-wrinkle effect of the composite back adhesive and Mylar sheet adhesion is improved. By setting the number of rubber support belts one to several, the stability of the rubber fixing belt one can be further increased after uniform distribution of the several rubber support belts one, and the high-viscosity back adhesive one can be supported to prevent deformation.
