Abstract
The invention discloses a waterborne polyurethane adhesive. The adhesive comprises the following components in part by mass: 350 to 450 parts of polyether glycol with a hydroxyl value of between 400 and 1,000, 70 to 100 parts of dimethylolpropionic acid, 300 to 400 parts of xylyl diisocyanate, 40 to 60 parts of triethylamine and 50 to 80 parts of butanediol. The waterborne polyurethane adhesive has the advantages of no toxicity, environmental friendliness, safety, noncombustibility and small odor due to that water is used as a basic medium.
Description
Technical field
The present invention relates to a kind of sizing agent, is a kind of aqueous polyurethane sizing agent specifically.
Background technology
At present adhesive for polyurethane type, kind are a lot, but most of adhesive for polyurethane adopt organic solvents, and its shortcoming is that organic solvent is inflammable and explosive, volatile, smell big, also can causes atmospheric pollution when using, but also has some toxicity.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of aqueous polyurethane sizing agent and preparation method thereof in order to overcome the deficiencies in the prior art, and this sizing agent is nontoxic, environmental protection, safety, and the preparation method of this sizing agent is simple, can reduce production costs.
Technical scheme: in order to solve the problems of the technologies described above, a kind of aqueous polyurethane sizing agent of the present invention, its component comprise that hydroxyl value is 400～1000 polyether glycol 350～450 mass parts, dimethylol propionic acid 70～100 mass parts, xylylene diisocyanate 300～400 mass parts, triethylamine 40～60 mass parts, butyleneglycol 50～80 mass parts.
In order to increase cohesiveness of the present invention, it also comprises the polyacrylic thickening material of 5～10 mass parts.
The present invention can make by the following method: with 350～450 mass parts polyether glycols and, 70～100 mass parts dimethylol propionic acids and 50～80 mass parts butyleneglycols mix, be heated to 130 ℃ and make the dimethylol propionic acid dissolving; Be cooled to 60 ℃, add 300～400 mass parts xylylene diisocyanates in batches; Stirring reaction in the time of 70 ℃ obtains performed polymer; 40～60 mass parts triethylamines are dissolved in solution in the frozen water; Performed polymer added in the described solution in stirring condition obtain emulsion; It is to stir in 25% ammoniacal liquor, water and the polyacrylic thickening material promptly to get described aqueous polyurethane sizing agent that emulsion is added mass content.
Beneficial effect: compared with prior art, the present invention is owing to be basic medium with water, therefore has nontoxic, environmental protection, safety, do not fire and advantage that smell is little; Because its viscosity is lower, and available water-soluble thickener and water regulates, and easy to operate, cull is easy to cleaning.
