Description
Technical field
The present invention relates to the macromolecular organic field that learns a skill, be specifically related to a kind of polyurethane resin composition that can be used for printing ink/coating preparation, single component, self-drying type and preparation method thereof.
Background technology
In the prior art, urethane resin is because of having excellent abrasion resistance, scuff resistance, weather resistance, solvent resistance, adhesiveproperties and good low-temperature performance, elasticity, sticking power, insulativity, gloss, gloss retention, and its adjustability is good, can satisfy various application requiring, be widely used.At present, urethane resin is the important source material of preparation printing ink, leather surface treatment agent, coating, especially urethane resin is that the coating of filmogen is that polyurethane coating (also being polyurethane paint) at first begins suitability for industrialized production by Germany the forties in 20th century, put into production in succession in various countries after the sixties in 20th century, and developed the kind of a lot of polyurethane coatings.Polyurethane coating has been widely used in applications such as footwear material, leather, fabric, chemical industry equipment, marine ship, electromechanical equipment, timber, cement, plays important effect in modern society.
If divide from component, polyurethane coating then has the branch of single component and two-pack; Two-pack is meant that polyurethane coating is divided into first, second two components, the first component contains isocyanate group, second component hydroxyl, need before the use at the construction field (site) two components to be mixed with composition according to a certain percentage, just can cover with paint, lacquer, colour wash, etc. after the two reaction, being easy to influences construction quality because of the metering mistake, complicated operation, to be subjected to the time during use, restrictions such as envrionment conditions, for example China's invention 85104908, China's invention 86101515, China's invention 87105713, China invention 90105044.X, China's invention 92113828.8, China invention 95195489.X, China's invention 00116520.8, China's invention 02111494.3, China's invention 03140686, U.S.'s invention 5260358, U.S.'s invention 4341689, U.S.'s invention 4983671, U.S.'s invention 5154950, U.S.'s invention 5502148, U.S.'s invention 6160075, U.S.'s invention 6169141, U.S.'s invention 6423816,6458898 disclosed technical schemes are invented by the U.S., all are to prepare the bicomponent polyurethane coating aspect; And one-can urethane coating is easy to use, and not needing to resemble needs user's allotment voluntarily at the scene the two-pack, coatings formulated surplus, out of date phenomenon also can not occur.
In existing various one-can urethane coatings, can be divided into moisture-curable, dead front type, self-drying type etc. again according to different curing modes.The rate of drying of moisture-curable polyurethane coating is subjected to the influence of humidity in the air, need under the bigger environment of moisture, place for a long time, curing molding gradually, in the winter time under the situation that temperature and humidity is all low, be difficult to solidify, and storage time is short, be easy to when storage, just solidify automatically because of airborne moisture, lose the value of use, for example China's invention 200310119059.4, China invention 200310119058.X, China's invention 200310119060.7,5138017 disclosed technical schemes are invented all about preparation moisture-curable polyurethane coating aspect by the U.S.; Though and blocked polyurethane paint has good storage stability because sealed isocyanic ester temporarily, need to open the isocyanate reacting group that is closed by improving temperature, thereby further reaction realizes curing molding, the temperature of heating sometimes will reach 150 ℃ even higher, this just need use in special occasion, also need to consume a large amount of heat energy, for example China's invention 95100827.7, U.S.'s invention 4005041, U.S.'s invention 4474937, U.S.'s invention 4478894, U.S.'s invention 5202406, U.S.'s invention 5541279, U.S.'s invention 5646228, U.S.'s invention 5728795, disclosed technical scheme all are about the preparation blocked polyurethane paint; The self-drying type polyurethane coating does not promptly need long-time placement the under the bigger environment of moisture, need not realize solidifying at a large amount of heat energy of special occasion consumption yet, it can be at any environment following within a short period of time of free curing molding, the while storage-stable, and still find no the technical scheme that disclosed comparatively complete, safe preparation single component self-drying type polyurethane coating is correlated with urethane resin product and method both at home and abroad.
The polyurethane coating of single component self-drying type also contains more free isocyanate usually with resin; this have certain toxic free isocyanate; when its content is higher; not only paint film property there is negative influence; also can environmental pollution; influence the healthy of workmen; therefore when the preparation polyurethane coating; all require the free isocyanate in the finished product is reacted; do not influencing under the product quality premise; it is safe low-level that the content of free isocyanate in the product is dropped to; and China's invention 99119948.0; China's invention 02109937.5; China's invention 01817800.6; China's invention 02804593.9; in China's invention 03118882.6, all unexposed this kind treatment process.
