The safe operation of train.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of polyisocyanate nylon is provided
Co-catalyst, including recipe ingredient and mass parts are as follows: 25 ~ 30 parts of diformazan phenylene diisocyanate, Toluene-2,4-diisocyanate, 4- diisocyanate
8 ~ 15 parts of ester, 50 ~ 60 parts of ethyl acetate solvent.
In a preferred embodiment of the present invention, recipe ingredient and mass parts are as follows: diformazan phenylene diisocyanate 53 ~ 60
Part, Toluene-2,4-diisocyanate, 15 ~ 20 parts of 4- diisocyanate, 30 ~ 37 parts of dichloromethane solvent.
In a preferred embodiment of the present invention, recipe ingredient and mass parts are as follows: 40 parts of diformazan phenylene diisocyanate, first
3 parts of benzene -2,4- diisocyanate, 45 parts of ethyl acetate solvent.
The beneficial effects of the present invention are: a kind of polyisocyanate nylon co-catalyst provided by the invention, can make nylon system
Tensile strength and bending strength of the product under high and low temperature environment are significantly reinforced, and excellent toughness of material is kept.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
The embodiment of the present invention includes:

Wherein, recipe ingredient and mass parts are as follows: 53 ~ 60 parts of diformazan phenylene diisocyanate, Toluene-2,4-diisocyanate, 4- diisocyanate
15 ~ 20 parts, 30 ~ 37 parts of dichloromethane solvent.By the above-mentioned means, can make the co-catalyst obtained to the synthesis of nylon have compared with
High catalytic efficiency.
Further, recipe ingredient and mass parts are as follows: 40 parts of diformazan phenylene diisocyanate, Toluene-2,4-diisocyanate, 4- diisocyanate
3 parts of ester, 45 parts of ethyl acetate solvent.By the above-mentioned means, it is lower that the co-catalyst obtained can be made to have the synthesis of nylon
Preparation cost.
In conclusion nylon products can be made in high/low temperature the present invention provides a kind of polyisocyanate nylon co-catalyst
Tensile strength and bending strength under environment are significantly reinforced, and excellent toughness of material is kept, and especially ensure that the peace of railroad train
Row for the national games.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
