Reason is analyzed, and the present invention is used by first preparing paper tire, then the maceration extract of preparation is coated with using coating method, can With the fiber that effectively prevent in filter process and other components, there is a phenomenon where movements, under differential pressure, the more difficult hair of the structure of filter core Change shape, is not susceptible to collapsing phenomenon, and is able to maintain filter paper pre-existent pore to keep good strainability, simultaneously The present invention is also creative in the preparation of maceration extract to have used polyvinyl acetate, N- octyl (methyl) acrylamide, uncle Raw material based on carboxylic acid vinyl ester and a variety of chemical substances of polyether polyol, auxiliary mixing tapioca, quaternary ammonium starch ethers, β- The mixing paste that cyclodextrine and alkyl glycosides, tricresyl phosphate are constituted, the maceration extract modest viscosity of formation can be effective The tensile strength of filter paper is improved, the synergistic effect of a variety of chemical substances effectively improves the mechanical property of paper, enhances its draftability Can, the introducing of starch improves the peel strength of maceration extract, its antioxygenic property can be improved in cycloheptaamylose, thus maceration extract It is not easy to foaming, while stability is also greatly improved, period of storage also greatly improves, the side that the maceration extract of configuration passes through coating Formula can effectively control the amount of coating, can reduce production cost and improve production efficiency, additionally it is possible to can effectively improve filter paper Physical performance index, predominantly tensile strength, bursting strength and stiffness can make to form discrete face between paper tire fiber It connects, slight crosslinking occurs between fiber, so that the mechanical strength of paper increases, moreover it is possible to realize the protrusion technology effect of barrier performance Fruit reduces paper to the wet performance of water, has reached preferable water resistance.

The present invention mixes wood pulp cellulose and straw pulp fiber with the secondary stock slurry in viscose rayon and waste paper, eliminates Original microdefect of single fiber raw material, the fiber synergistic effect that a variety of thicknesses are different, toughness is different, while using Four acicular type zinc oxide crystal whisker increased fiber interacts area and interface binding power so that filter paper have preferable mechanical strength and Endurance, while forming preliminary paper tire after squeezing by wet-laying web-forming equipment so that paper structure is stablized, between fiber between Gap rate is ideal, and air penetrability is preferable, while that adds is made of shell powder, bentonite, mica stone powder and attapulgite On the one hand mixed-powder promotes paper molding, improves the intensity of paper, on the other hand also improve the filterability of filter paper Can, mixed-powder has preferable absorption property, there can be preferable suction-operated for dust, the pollution gas in air, Furthermore there are also preferable bactericidal effects for shell powder, while the titanium dioxide added can be improved the ageing-resistant line of filter paper, addition Zinc oxide can be improved the bactericidal property of filter paper.

The plant sterilization flavouring extracting solution added in maceration extract in the preferred embodiment of the present invention simultaneously, on the one hand can allow The filter paper paper prepared has certain sterilization, on the other hand expelling parasite killing ability makes it have certain plant fragrance of a flower, effectively Improve indoor air, while vegetalitas sterilizes non-toxic to humans, safety and environmental protection, special standby suitable this kind of confined space of vehicle It uses.

The mixed rare earth chlorides of its weight 5% also are accounted in mixture addition in the preferred embodiment of the present invention, cooperate starch The phenomenon that using, the paper in later period can effectively be avoided to turn to be yellow, the chitosan of addition, which to mix, more uniform is distributed in fiber Plain surface and there are apparent retention, filtrating aid function preparing paper tire process.

The glass fibre added in mixed serum in the preferred embodiment of the present invention can effectively improve the porosity of paper tire, 4% selection is that inventor's repetition test can reach effect without making the quantitative criterion of filter paper hairiness thorn stick.

Medium consistency refining mode is used in the preferred embodiment of the present invention, so that the length of fiber, rugosity, kink and crimp index Achieve the effect that best, this is that inventor is serendipitous in repetition test during invention.

The index effect of comprehensive upper table simultaneously, the indices of embodiment 1-3 are although better than comparative example, embodiment Also difference between 1-3, it is seen that the selection of the content and preparation method parameter of component also have to final performance it is most important, therefore And the innovative content selection aspect for being also embodied in each component simultaneously of the invention, certain remaining component selection of the present invention and content Selection is obviously also non-obvious, and those skilled in the art combine the prior art that can readily occur in absolutely not.

The filter paper air permeability that the method for the environmentally protective manufacture high-quality air filter paper of one kind provided by the invention is prepared compared with Good, lower to gas-flow resistance, filter efficiency is excellent, and filter paper has the function of the plant fragrance of a flower, antimycotic antiseptic, effective mosquito expelling, Resistance to deformation, resistance to compression difference ability and the bursting strength of filter paper have preferable performance simultaneously, furthermore use a large amount of wastes, reduce Cost, protects environment, has saved resource, practical value with higher and good application prospect.

It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims Variation is included within the present invention.
