Abstract
The invention relates to a super-hydrophobic and self-cleaning surface modification method for paper. The modified method comprises the steps: a layer of uniformly arranged surface layer is assembled on the surface of the general paper by utilizing nano silica spherical particles or a polytetrafluoroethylene powder, silica gel and soluble polytetrafluoroethylene, and the surface modified paper having the color, the luster and the strength similar to those of the original paper and having the surface with super-hydrophobic and self-cleaning characteristics is obtained. A hydrophobic contact angle of the super-hydrophobic and self-cleaning surface modified paper can maximally reach 160 DEG. The super-hydrophobic and self-cleaning surface modification method is simple; the modified paper not only keeps the original performance of the general paper, but also has moisture-proof and self-cleaning functions, and has soft optical properties suitable for human eye observation; and the expansion and contraction rate of the paper is decreased by about one third.

Background technology
Along with the high speed development of World Economics and information, people not only increase considerably the demand of paper, and also more and more higher to the quality requirement of paper.Particularly publish, print, the paper of the class such as office, there is printable, duplicating, printing, writing quality, but the WATER RESISTANCE on plain paper surface is lower, rear intensity and the deflection of making moist reduces greatly, simultaneously along with time growth, the easy yellowing of paper, roughness descent.
To the surface treatment of plain paper, more report as existing as organosilicon, fluorine compounds etc.It can play paper adhesion in process of production, do not tear, thereby reduction in the numbers of seconds is accelerated paper production speeds, improves quality; Reduce friction and wear simultaneously, make printing evenly, thereby improve print speed printing speed and print quality.Patent of invention 02147804.X has reported employing silica gel and ethyl acetate, n-butyl acetate or banana oil prepare hydrophobic nano structural table facial tissue.But, so far also there is not yet the relevant nano silicon spheric granules, polytetrafluoroethylene (PTFE) of adopting at the even superficial layer of row section of plain paper surface-assembled one deck, obtain a kind of color and luster, intensity and printable, duplicating, printing, writing quality are the same with former paper, and that surface has is super-hydrophobic, the report of the surface modification paper of automatically cleaning characteristic.
Summary of the invention
The objective of the invention is to utilize nano silicon spheric granules or polytetrafluoroethylene powder, silica gel and soluble poly tetrafluoroethylene at the even superficial layer of row section of plain paper surface-assembled one deck, obtain a kind of surface and there is surface modification paper super-hydrophobic, the automatically cleaning characteristic.
A kind of paper is super-hydrophobic, the self-cleaning surface method of modifying, described paper is super-hydrophobic, the self-cleaning surface method of modifying is on the plain paper surface, utilize nano silicon spheric granules (particle diameter is 20-150nm) or polytetrafluoroethylene powder, silica gel (south famous 703, 704 or 705 silica gel), soluble poly tetrafluoroethylene and organic solvent (ethyl acetate, butyl acetate, pentyl acetate, isoamyl acetate etc.), even row section hydrophobic of plain paper assembling one deck, the self-cleaning surface layer, printing, duplicate, printing, in the constant situation of writing quality, the hydrophobic contact angle of paper surface can reach 160 °, there is protection against the tide, self-cleaning function.
Super-hydrophobic, self-cleaning surface method of modifying of the present invention comprises the following steps:
(1). nano silicon spheric granules or polytetrafluoroethylene powder, silica gel, soluble poly tetrafluoroethylene are mixed with certain proportion, and making its percentage by weight is 1-1.5: 1-3: 1
(2). the mixture of (1) is dissolved or is dispersed in organic solvent, its mixture: the percentage by weight of organic solvent is: 1: 150-250.
(3). the ultrasonic dispersion of the suspension 5min by (2) preparation makes it dispersed.
(4). at room temperature, plain paper is soaked in the suspension of (3) gained, after taking out, natural airing or oven dry under 50 ℃, obtain super-hydrophobic, self-cleaning surface modified paper.
The present invention adopts at the even superficial layer of row section of plain paper surface-assembled one deck, obtains a kind of surface and has surface modification paper super-hydrophobic, the automatically cleaning characteristic.It has not only kept original performance of plain paper, and after modification, paper has protection against the tide, durable, feel is fine and smooth, the soft optical property of practical human eye observation, and there is the functional characteristic of self-cleaning surface.
A kind of paper of the present invention is super-hydrophobic, the self-cleaning surface method of modifying is simple, simple operation, and cost is low, and the hydrophobic contact angle of paper reaches as high as 160 °, and paper formation degree, intensity and Ting Du improve, and expansion and contraction significantly falls.
