Abstract
The invention relates to the macromolecule material and chemical technical field, in particular to a preparation method of an improved polyurethane glue. The preparation method is characterized in that: an organic solvent A is heated to 35DEG C to 60DEG C, stirred at 600revolution/min to 1000revolution/min and added with polyurethane grains B gradually simultaneously; the addition of the added polyurethane grains B is 20 percent to 60 percent of the weight of the organic solvent, and then reaction is carried out for 5h to 10h; after the dissolution of the grains, an anti-freezing modifier C is added, stirred and mixed; according to needs, other auxiliary agents D are added, stirred and mixed fully, and the temperature is lowered to 20 DEG C to 35 DEG C; and the macromolecule material is obtained by filtering and packaging. The addition of the anti-freezing modifier accounts for 0.01 percent to 10 percent of a finished improved polyurethane glue system according to weight percentage. The beneficial results of the preparation method includes: the improved polyurethane glue can be utilized at 15 DEG C below zero to 5 DEG C, the temperature required in storage and utilization of a crystalline polyurethane glue is reduced, thereby being widely applicable to the industries of clothes, automobiles and furnitures, and bringing fortune to a broad range of users of a similar glue in freezing regions.
Description
[technical field]
The present invention relates to macromolecular material and chemical technology field, is a kind of preparation method of modified polyurethane glue specifically.
[background technology]
Polyurethane adhesive with highly crystalline performance has fast doing and the good advantage of cohesive strength, but because frozen glue problem, temperature severe cold zone particularly in the winter time, have a strong impact on and use and deposit, during tradition is used, manufacturing enterprise and user have to build that insulated building is deposited or adopted various heating measures before using, to recover the use properties of glue.
[summary of the invention]
The objective of the invention is to make polyurethane glue under-15 ℃ of conditions, to deposit and to use with highly crystalline structure.
For achieving the above object, design a kind of preparation method of modified polyurethane glue, it forms part: organic solvent A, be warming up to 35～60 ℃, with rotating speed is that 600～1000 commentaries on classics/min progressively add polyurethane particles B when stirring, add-on is 20～60% of an organic solvent weight, reaction 5～10h, treat that particle dissolves the back fully and adds freeze proof properties-correcting agent C, fully mix 30～90min, add as required or do not add other auxiliary agents D and fully mix 30～90min, be cooled to 20～35 ℃ then, filter and package, get product, the add-on of described freeze proof properties-correcting agent is by weight percentage than accounting for 0.01%～10% of finished product modified polyurethane glue system.
Described mixed organic solvents A is one or more a mixture in acetone, butanone, pimelinketone, vinyl acetic monomer, N-BUTYL ACETATE, toluene, tetrahydrofuran (THF), N ' the N-dimethylformamide, wherein with acetone, one or both mixture effect the bests of butanone.
Described polyurethane particles B can be one or more the mixture in commercially available any crystalline TPU particle, when multiple mix particles is used, can adopt any blending ratio as required, but total amount is no more than 60% of weight of solvent.
The compound that described freeze proof properties-correcting agent C is ethene acetate polymer and high boiling solvent is as one or more the mixture in the diesel pour inhibitor.
Described other auxiliary agent D is one or more mixtures in oxidation inhibitor, uv-absorbing agent, the photostabilizer, and this auxiliary agent D not necessarily can add as required.
Beneficial effect of the present invention: adopt the polyurethane glue of the technology of the present invention preparation under-15 ℃～5 ℃ cold condition, to use, filled up the prior art blank, the storage and the use temperature of crystallinity polyurethane glue have been reduced, can be widely used in clothes, automobile and furniture industry, similar glue user brings glad tidings for vast severe cold area.
