The preparation method comprises the following steps of: adopting methyl methacrylate (MMA), ethyl acrylate (EA) and acrylic acid-2-ethylhexyl acrylate (2-EHA) as raw materials to prepare prepolymer, adding an acrylic acid diluent for diluting, using nitrile butadiene rubber (NBR) to carry out modification, adding lauryl mercaptan (NDM) and preparing the nitrile butadiene rubber-acrylate UV (Ultraviolet) curing pressure-sensitive adhesive. The pressure-sensitive adhesive disclosed by the invention has excellent caking property and environmental protection property.
Description
Technical field
The present invention relates to the preparation method of a kind of paracril-acrylate UV solidified pressure-sensitive, belong to chemical field.
Technical background
The UV photocuring is that light trigger resolves into free radical and causes unsaturated organic monomers generation polymerization, grafting, the reaction such as crosslinked under the UV radiation, realizes fast a kind of technology of solidifying at matrix surface.UV solidified pressure-sensitive system does not generally contain volatile organic solvent, need not drying and processing, can form cross-linked network during curing, has high resistance toheat.In addition, compare with traditional thermofixation technology, UV curing also has the advantage that curing speed is fast, energy consumption is low.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of paracril-acrylate UV solidified pressure-sensitive, the pressure sensitive adhesive that obtains has excellent cohesiveness and the feature of environmental protection.
For realizing above purpose, the preparation method of a kind of paracril of the present invention-acrylate UV solidified pressure-sensitive, its step is specially:
In the time of (1) 65 ℃, start stirring, rotating speed is 600r/min, take methyl methacrylate (MMA), ethyl propenoate (EA), acrylic acid-2-ethyl ethyl ester (2-EHA) as raw material prepares performed polymer, reacts 2h;
(2) add diluting monomer vinylformic acid (AA) to performed polymer dilution 30min;
(3) add paracril (NBR) carry out cross-linking modified, reaction 1.5h;
(4) add sodium laurylsulfonate (NDM), stirring reaction 30min, rotating speed is 1000r/min, makes paracril-acrylate UV solidified pressure-sensitive.
Wherein the consumption of MMA is 10 parts, and the consumption of EA is 15 parts, and the consumption of 2-EHA is 17 parts, and the consumption of AA is 5 parts, and the consumption of NBR is 10-15 part, and the consumption of NDM is 2 parts.
The beneficial effect that the present invention produces is, this patent prepares performed polymer take methyl methacrylate (MMA), ethyl propenoate (EA), acrylic acid-2-ethyl ethyl ester (2-EHA) as raw material, (NBR) carries out modification with paracril, finally makes paracril-acrylate UV solidified pressure-sensitive.Bulk polymerization between acrylate monomer has generated linear propylene's acid ester polymer, after introducing the NBR modification, so that the unsaturated carbon-carbon double bond generation graft reaction among acrylate monomer and the NBR, thereby make the solidified pressure-sensitive that makes form crosslinking structure, so that the cohesiveness of product is good.In addition, because the product of preparation does not contain solvent, so paracril-acrylate UV solidified pressure-sensitive has the very strong feature of environmental protection.
