Abstract

The invention relates to the technical field of multifunctional sealants, in particular to preparation of a multifunctional sealant for optical bonding. The multifunctional sealant comprises alkoxy-terminated polyether, a plasticizer, a filler, modified white carbon black, a coloring agent and a catalyst, and in the preparation of the multifunctional sealant for optical lamination, alkoxy-terminated polyether adhesive which is high in thixotropy, low in hardness, adjustable in curing rate and high in strength is used as the multifunctional sealant for optical lamination box dam-sealing, and different performances of the sealant can be further improved; Addition of the colorant facilitates the color modulation of the sealant, effectively improves the tensile strength, elongation, shear strength, hardness and droop resistance of the sealant, improves the appearance performances, and allows fumed silica to have good reinforcing property, thixotropy and thickening property, so the fumed silica has good adhesion to the sealant along with increase of the use amount of the fumed silica, and the sealant has increased viscosity and excellent thixotropy.

Description

technical field [0001] The invention relates to the technical field of multifunctional sealants, in particular to the preparation of a multifunctional sealant for optical bonding. Background technique [0002] Water glue can be used in different fields according to different thicknesses, and its main uses are: electronic paper, transparent device bonding, projection screen assembly, aerospace or military optical device assembly, display assembly, lens assembly, resistive touch screen, capacitive touch screen , panel, ICON and plastic materials such as glass and polycarbonate; [0003] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the configuration gap and play a sealing role. heat insulation, etc.; [0004] The water glue is in a liquid state and requires dam glue enclosure and height limit. The strength of the water glue is weak and needs to...
