Description
Technical field
The present invention relates to a kind of polyamide resin, be specifically related to a kind of environment-friendly type high rigidity alcohol-soluble polyamide resin and application thereof.
Background technology
Polyamide resin, is the broad-spectrum industrial chemicals of excellent property, has good over-all properties, comprise mechanical property, thermotolerance, wearability, chemical proofing and self lubricity, and frictional coefficient is low, have certain flame retardant resistance.Polyamide resin is widely used in ink area because of its characteristic property, and existing Polyamide Resins for Printing Ink is in alcoholic solvent, and solubleness is poor, so also need to add a certain amount of as the aromatic solvent such as benzene, toluene.Along with the reinforcement of environmental consciousness, numerous and confused requirement has the polyamide resin of complete alcohol dissolubility, although current domestic more existing reports about alcohol-soluble polyamide resin, but ubiquity color is darker, poor transparency, gel tendency is serious, the problems such as the restorative difference of gel.CN103554486A discloses a kind of preparation method of alcohol dissolubility dimer acid type polyamide resin, and it mainly through adding properties-correcting agent to change the solvability of polyamide resin, but makees ink, after film forming hardness and anti-reflective viscosity poor.
In view of this, need to invent a kind of environment-friendly type high rigidity alcohol-soluble polyamide resin, to make up the deficiencies in the prior art.
Summary of the invention
The object of the invention is to the defect overcoming prior art, a kind of environment-friendly type high rigidity alcohol-soluble polyamide resin is provided, and its purposes is provided simultaneously.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of environment-friendly type high rigidity alcohol-soluble polyamide resin, its key technical feature is, is made up of following massfraction raw material:
