The invention discloses a kind of non-solvent single-component polyurethane casting resins, raw materials used include: 100 parts of polyether polyol, 3.0 ~ 10.0 parts of toluene di-isocyanate(TDI), 15.0 ~ 30.0 parts of 4,4`- methyl diphenylene diisocyanate, 1.8 ~ 9.0 parts of chain extender, 4.0 ~ 6.0 parts of sealer, 0.4 ~ 0.6 part of levelling agent, 0.1 ~ 0.2 part of antioxidant by weight.Resin material of the present invention is raw materials used to be easy to get, and synthetic method is succinctly efficient, at low cost and easily operated, it is easy to carry out industrialized production, it and due to the addition of toluene di-isocyanate(TDI), can make gained resin material that there is good adhesion strength, and can be used for the continuous-upper injection of sole.
Description
Technical field
The invention belongs to field of material preparation, and in particular to a kind of non-solvent single-component polyurethane casting resin.
Background technique
The volatilization of solvent gradually can be avoided with solventfree resin substitution solvent resinoid and resulted in waste of resources, reduction pair
The pollution of environment keeps downstream shoes synthetic leather and its product more environmentally-friendly；Synthetic leather manufacturing enterprise does not need dirt without technique waste water
Water processing establishment；Without industrial residue, solve the problems, such as the solid slag and dangerous Solid state fermentation in solvent resin manufacturing processes；It is comprehensive
Low energy consumption, does not need three-protection design, reduces the consumption of water, electricity and gas and human resources in removal process；There is no organic solvent
It is also of great advantage using the physical and mental health to worker.
Summary of the invention
It is strong with bonds well the purpose of the present invention is to provide a kind of non-solvent single-component polyurethane casting resin
Degree, the use of the solvent type polyurethane resin of alternative high pollution.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of non-solvent single-component polyurethane casting resin, raw materials used include: 100 parts of polyether polyol, first by weight
3.0 ~ 10.0 parts of phenylene diisocyanate, 15.0 ~ 30.0 parts of 4,4`- methyl diphenylene diisocyanate, 1.8 ~ 9.0 parts of chain extender,
4.0 ~ 6.0 parts of sealer, 0.4 ~ 0.6 part of levelling agent, 0.1 ~ 0.2 part of antioxidant.
Wherein, the polyether polyol is the polyether polyol of 2 degrees of functionality.The chain extender is ethylene glycol, 1,4- fourth two
One or more of alcohol, diethylene glycol etc..The sealer is methylation amino resins.The levelling agent is polyether-modified poly-
Siloxanes levelling agent.The antioxidant is suffocated amine antioxidant.
The non-solvent single-component polyurethane casting resin the preparation method comprises the following steps: by polyether polyol, chain extender dehydration after
It is reacted 2 hours under the conditions of 90 DEG C with toluene di-isocyanate(TDI), is then cooled to 70-80 DEG C, 4,4`- diphenyl methane two is added
Isocyanates stirs 2 hours, adds sealer, levelling agent and antioxidant and stirs evenly to obtain the final product.
The non-solvent single-component polyurethane casting resin can be applied to the continuous-upper injection of sole, application method are as follows:
During preparation injection molding leather, the non-solvent single-component polyurethane casting resin is coated uniformly in release paper, 120 DEG C of bakings
After dry, after being bonded release paper with cloth, it is anti-to place progress open loop in 1.5 ~ 2.0 minutes in 150 DEG C of baking ovens for spot printing thermosol
It answers.
Remarkable advantage of the invention is:
(1) use for passing through structural asymmetry toluene di-isocyanate(TDI) in the present invention can be such that gained resin material has good
Adhesion strength, therefore can greatly improve the bonding intensity of sole and upper of a shoe (injection molding is removed from office) during sole continuous-upper injection.
(2) the raw materials used in the present invention is easy to get, and synthetic method is succinctly efficient, at low cost and easily operated, is easy to carry out industry
Metaplasia produces.
(3) present invention gained non-solvent single-component polyurethane casting resin can be used for substituting the solvent borne polyurethane of high pollution
Resin.
