Abstract
The invention provides a kind of waterborne polyurethane resin for film printing varnish and preparation method thereof.This waterborne polyurethane resin comprises each composition of following parts by weight: polymer polyatomic alcohol 90-110 part, dimethylol propionic acid 6-8 part, TriMethylolPropane(TMP) 0-0.5 part, isophorone diisocyanate 30-40 part, triethylamine 0.4-0.6 part, water 300-350 part.Its preparation method is reacted at polymer polyatomic alcohol, dimethylol propionic acid and TriMethylolPropane(TMP) and isophorone diisocyanate, and add the waterborne polyurethane resin that triethylamine and water-dispersion obtain.Prepared urethane resin and PE, PET film has similar snappiness, and coating has higher sticking power simultaneously.

Urethane (PU) refers to the abbreviation of the superpolymer polyurethane(s) (Polyurethane) containing a large amount of carbamate groups (-NHCOO-) on main chain.By feed change kind and composition, product form and performance thereof can be changed significantly, obtain from softness to hard the finished product.Line style and build two kinds can be divided into by its molecular structure.Because cross-linking density is different in three dimensional structure, hard, soft or Jie's performance between the two can be presented, there is the features such as high strength, high abrasion and solvent resistant.
Urethane resin is mainly divided into oiliness urethane resin and waterborne polyurethane resin.Oiliness urethane resin is that superpolymer polyurethane(s) is dissolved in dimethylformamide (DMF), organic solvents such as toluene and obtaining.Superpolymer polyurethane(s) is scattered in water by waterborne polyurethane resin to be made.In current leather-making enterprises, more than 90% still uses oiliness urethane resin, is only using waterborne polyurethane resin less than the enterprise of 10%.
Oiliness urethane resin contains a large amount of dimethylformamides (DMF), the organic solvents such as toluene, causes very major injury in the fabrication process to surrounding environment and the healthy of site operation personnel.Because chemical solvents is most of inflammable and explosive, hold fire hazardous, therefore oleoresin becomes the No.1 threat of leather industry " three is high ".In addition, the product that oiliness urethane resin makes, when not adding fire retardant, does not have fire-retardant performance yet.
Aqueous polyurethane is the new polyurethane system using water to replace organic solvent as dispersion medium, also claims water dispersible polyurethane, aqueous polyurethane or waterbased urethane.Aqueous polyurethane take water as solvent, have pollution-free, safe and reliable, good mechanical performance, consistency are good, be easy to the advantages such as modification, are widely used in coating, tackiness agent, fabric coating and finishing composition, hide finishes, sheet surface treating agent and Fiber strength agent.
The adhesion layer be currently used on metallized film mainly uses solvent-based varnishes, can cause a large amount of VOC discharges in production and application.And the sticking power of existing water varnish in PET film is poor, being difficult to especially on PE film adheres to.And use a large amount of auxiliary agents that the compactness of coating can be made to decline to increase sticking power, easily punctured by aluminium atom in follow-up vacuum plating operation and cause the glossiness of aluminium coated to decline, becoming mute, affect sticking power, affect the decorative effect of coating.
