Abstract

The invention provides an ultraviolet light curing non-woven adhesive tape and a preparation method thereof. The ultraviolet light curing non-woven adhesive tape is prepared from ultraviolet curing type polyacrylate coating liquid, and the ultraviolet curing type polyacrylate coating liquid is prepared from the following components in parts by weight: 60-120 parts of acrylate oligomers, 0.1-1 partof a cross-linking agent, 0-40 parts of tackifying resin and 0.05-0.5 part of a photoinitiator, wherein the ultraviolet curing type polyacrylate coating liquid does not contain a solvent. The ultraviolet light curing non-woven adhesive tape is coated through a one-step method and prepared by ultraviolet curing, post curing is not required, and production hours are more saved; and the prepared ultraviolet light curing non-woven adhesive tape has a transparent appearance, does not contain the solvent, and is environmentally-friendlier, interlayer damage is not prone to being produced, cohesiveness is good, and viscosity is lasting.

Description

technical field [0001] The invention belongs to the technical field of non-woven tapes, and relates to a non-woven tape and a preparation method thereof, in particular to an ultraviolet-cured non-woven tape and a preparation method thereof. Background technique [0002] Non-woven tapes used in the electronics industry are usually based on non-woven fabrics, coated with solvent-based (or hot-melt) pressure-sensitive adhesives on both sides and attached with release paper or film on one side. There is a layer of non-woven fabric substrate, which has better die-cutting and better strength than ordinary non-substrate pressure-sensitive tapes, and better compliance than double-sided tapes of other substrates (such as PET) Therefore, it is widely used in the bonding and fixing of electronic components, flexible circuit boards FPC, mobile phone accessories, metal nameplates, etc. [0003] In the prior art, the preparation method of solvent-based non-woven double-sided adhesive tap...
