Abstract

The invention discloses a nano material modified acrylate pressure-sensitive adhesive which is composed of the following components by the weight percentage: 45 to 52% of a soft monomer, 3 to 6% of ahard monomer, 5 to 10% of a functional monomer, 1.5 to 4.5% of an emulsifier, 0.1 to 0.3% of an initiator, 0.15 to 0.25% of an oxidant, 0.5 to 1% of ammonia water and the balance being deionized water. According to the modified acrylate pressure-sensitive adhesive, titanium dioxide and graphene oxide are added into the functional monomer to be mixed to modify the functional monomer; the surface electrical resistivity of the pressure-sensitive adhesive can reach 1*10<5> ohm or above, the aging resistance and 70 DEG C yellowing resistance of the pressure-sensitive adhesive can be remarkably improved, and the pressure-sensitive adhesive is a novel transparent and beautiful pressure-sensitive adhesive material.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to a nano-material modified acrylate pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is an adhesive that is sensitive to pressure during the bonding process. Under the action of small pressure, a large bond can be formed. Acrylic pressure-sensitive adhesives are widely used in many fields because of their good light resistance, aging resistance and water resistance, and good pressure sensitivity, adhesion and stability. [0003] However, traditional pressure-sensitive adhesives have poor performance in terms of electromagnetic shielding, high temperature resistance, and yellowing resistance, so it is necessary to modify the raw materials and methods of preparation. Therefore, the present invention provides a nano-material modified acrylate pressure-sensitive adhesive and a preparation metho...
