Description
Technical field:
The present invention relates to the papermaking material preparing technical field, particularly a kind of preparation method of super-hydrophobic, self-cleaning papermaking coating.
Background technology:
Along with the needs of market development, people more and more pay attention to the pursuit to quality of finished paper, performance and taste, have promoted the development of painting processing paper and coated board in the paper industry.Generally, not surface treated plain paper all has stronger hydrophily, once contact with water, water meeting rapid osmotic, to paper inside, causes the paper mechanical properties decrease, finally loses use value.Painting processing paper is mainly to spread pigment, sizing material and the special coating of various performances on the surface of paper, has the requirement (as surface strength, appearance colour, wear-resisting, waterproof and environmental-protecting performance etc.) of property to adapt to paper.The paper prepared through common coating process, its surface all is less than 120 ° with the contact angle of water usually, does not possess ultra-hydrophobicity, let alone automatic cleaning action.
The super-hydrophobicity of the surface of solids (contact angle is greater than 150 °, and roll angle is less than 10 °) is the important physical characteristic of material surface, and biomaterial surface has been given us many important inspirations, and lotus leaf surface is exactly a most typical class.Find through long-term observation, exist very complicated micron and nano level binary composite construction on lotus leaf surface.Under scanning electronic microscope, can clearly see, lotus leaf surface has many small mastoid processes, and the protruding top of " small hill " shape of many diameters 200 nanometer left and right is arranged again on the surface of each mastoid process.Sunk part between mastoid process and " small hill " is air abrim.After rainwater drops on blade face, can only be with the protruding top forming portion branch contact of " small hill " on blade face.Research shows, this micro--nanometer diadactic structure pattern do not exist only in lotus leaf surface, in the fur of other plant surface and some animals, also exist this micro--nanometer binary rough surface structure.
In general, can prepare by two kinds of approach by super hydrophobic surface: a kind of is roughness and configuration of surface at hydrophobic material surface modification material surface; Another kind is the material of modifying low-surface-energy on the surface of certain roughness having.At present, many methods that prepare rough surface have been reported, for example, when polytetrafluoroethylene (PTFE) exists polyacrylic plasma polymerization or etching, phase separation method and template etc.Simultaneously, in order to obtain super hydrophobic surface, it is also necessary with low-surface-energy organic resin (as fluorine silicon resin), product surface being modified.As U.S. Patent No. 6,800,354 are coated in by the coating that will have nanometer oxide particle the self-cleaning surface that substrate surface forms.It has formed nanoscale structures on the micron order structure, micro particles in coating is uniformly distributed in coating, or first the ground floor coating of micro-size particles is coated to substrate, the second layer coating that will have again nanometer particle is coated on ground floor, and coating is mainly to adopt material (for example organosilan) processing of hydrophobization to make hydrophobic surface.Chinese patent (application number is 200810031648.X) " containing the super-hydrophobic water-based fluorine silicon-acrylic coatings of nano particle " and for example, disclosed coating is that the component mixed preparing by following mass fraction forms: water 30%～65%, Silicone acrylic emulsion 10%～40%, water-based fluororesin emulsion 10%～40%, nanometer oxide particle 1%～10%, inorganic drilling compound 1%～15%, also have a small amount of inorganic acid for regulating pH value; This invention also discloses super-hydrophobic water-based fluorine silicon the third coating that this coating preparation of a kind of use obtains, and the water static contact angle of this coating is more than 150 degree, and roll angle is below 5 degree; Utilize coating that the coating preparation of this invention obtains to combine the advantages such as super-hydrophobicity, excellent mechanical property and workability, possess the self-cleaning property function as lotus leaf.Also has Chinese patent (application number is 02147804.X) " super-hydrophobic, self-cleaning nano structural table facial tissue ", this paper is on the plain paper surface, application silica gel (703,704,705), ethyl acetate, n-butyl acetate and banana oil, prepare that one deck is super-hydrophobic, self-cleaning nano structural table surface layer; Form one deck air film between nano structure superficial layer and the globule, super-hydrophobic angle is greater than 150 degree, and sewage splashes surface and can automatically tumble, and does not stay any vestige, reaches the purpose of self-cleaning.
But the current this rough surface structure of first constructing, there is a more difficult problem in the two-step mode technique that carries out again the silicon fluoride finishing, face need special sophisticated equipment (as plasma apparatus) or use expensive macromolecular material (as surface can be extremely low silicon fluoride) dilemma, but also need pay very large environmental protection cost, this all is unfavorable for that it realizes large-scale industrialization application.
Summary of the invention:
For the existing deficiency of prior art, the object of the present invention is to provide a kind of preparation method of coating, the method has that operating procedure is simple, cost is low, and is easy to the characteristics such as suitability for industrialized production; Super-hydrophobic, self-cleaning function that its product has, can be used for papermaking.
