Fluorine changes polyurethane - acrylic ester latex considers to make progress (

As the accentuation of force of double weigh of environmental protection and the sources of energy, coating of ability in swimming is being produced with its, carry and the feebleminded bad news in construction process, low cost and low VOC discharge one of focal points that wait for a characteristic and make new-style coating progress. Polyurethane of ability in swimming (PU) coating has unique two-phase structure and have the good flexibility, adhesiveness to base material and fight cut sex and drawing sex exceedingly goodly, but be able to bear or endure the function such as the solid content that awaits gender, mechanical intensity, coating, luster that adds stiff sex and film oneself is not worth; and polypropylene acerbity ester (PA) latex is behaved in this respect just exceedingly good. Accordingly, polyurethane - acrylic ester (PUA) latex has both collective advantage and the inadequacy that made up for both sides, the synthetic method that domestic and international scholar had studied PUA latex in great quantities and latex function and film function [1-3] .


In the compound that contain fluorine, the C that forms between fluorine atom and carbolic atom, the key that F bolts electron cloud of atomic of can big, fluorine is right C, the screen action that C bolts is very strong. Contain fluorine compound to have exceedingly good low face from this can, be able to bear or endure sex of ability in swimming, oil resistant, lubricity, hear resistance, be able to bear or endure chemical sex and be able to bear or endure flyblow sex and good biology consistence. Accordingly, of fluorine introduce the exterior performance that can improve film substantially, thereby the quality that land of very old rate improved coating. Fluorine changes polyurethane - acrylic ester (FPUA) latex was gifted again on the foundation of the performance with its superior oneself be able to bear or endure distinctly sex of ability in swimming, oil resistant and be able to bear or endure flyblow sex, had become the development delegate of latex of new generation PUA.

The structure of 1FPUA latex feature
