4) glass fibre is joined step 3) form pulp in the slurry of gained;
5) by the wet strength agent dilute with water of formula ratio, stir, slowly join in pulp;
6) by the defoamer of formula ratio, dispersant, waterproofing agent, brightening agent joins step 5) pulp in, stir, obtain pulping, slurry concentration is 1.58 ~ 1.98%;
7) by step 6) pulping that obtains routinely condition online manufacture paper with pulp and squeeze and obtain body paper;
8) impregnating agent is configured, by the phenolic resins of formula ratio, benzene emulsion, n-hexane, methyl alcohol, N hydroxymethyl acrylamide, wetting agent, N, N'-piperazine four phenoxy urethane phosphate, TDE are put into reactor at the temperature of 70 ~ 90 DEG C and are stirred fully, mixing time is 2 ~ 6hr, then be cooled to room temperature, obtain impregnating agent by 50 ~ 100 order filtered through gauze;
9) by step 7) obtain body paper and be immersed in step 8) in impregnating agent in, adopt the print roll coating mode of intaglio plate reticulate patterned surface to flood, controlling spread is 20% ± 0.5%;
10) after dipping, pattern solidifies in 150 DEG C ~ 160 DEG C circulating airs.
The application of above-mentioned fire-retardant air paper in engine art.
Filter paper has has resistance to flowing, the characteristic that filter efficiency is high and dust capaciting ability is strong, these performances are all relevant with the distribution of porosity and pore size, and fibrous raw material directly can affect the aperture of filter paper, micron filter efficiency, the intensity of wet web when porosity and paper machine operation, so select which type of fibrous raw material, most important to the preparation of filter paper, the present invention adopts and selects glass fibre, all-glass paper is owing to having high filter efficiency, good stability and lower resistance and become the preferred material of efficient especially ultra high efficiency air filter, and its outer cotton pulp that adds selected extends cleaner life-span and pollutant energy to improve dust containing capacity, add synthetic fiber and add ultrasonic wave end socket needs in man-hour to improve filter paper deflection and to meet filter core, ensure that the stability of quality.
Beneficial effect of the present invention:
1. the present invention adopts the mixing of glass fibre, short fibered pulp and acid fiber by polylactic to join the high porosity and enough little aperture copying and ensure that filter paper, aperture is enough little can effectively tackle passing through of dust, wherein acid fiber by polylactic manufactured goods can be analyzed to carbon dioxide and water after discarding in soil, during burning, poison gas can not be distributed, can not pollute, be a kind of ecological fiber of sustainable development.
2. use PPE wet strength agent, obtained body paper wet strength is high, long service life, and PPE wet strength agent has the effect of retention, drainage in paper-making process simultaneously, promotes paper quality; Add waterproofing agent, the WATER RESISTANCE of filter paper can be increased; Add dispersant, synthetic fiber uniformity in the slurry can be improved; Add defoamer, the stability of filter paper quality can be ensured; Add brightening agent, increase the whiteness of filter paper.
3. adopt long fiber pulp, the short fibered pulp through special process process, the combination both ensureing can form aperture and the porosity of expection, also removes the impurity in fiber, guarantees the content of fiber, ensure the quality of filter paper.
4. adopt the print roll coating mode of special impregnating agent and intaglio plate reticulate patterned surface to rely on the natural absorbability of body paper, resin is adsorbed onto in body paper equably, and the evaporation of solvent or resin are reclaimed, reduce production cost and enhance productivity all being highly profitable.
5. two kinds of reactive flame retardant N introduced by chemical reaction method in impregnating agent, have been used, N'-piperazine four phenoxy urethane phosphate and TDE, TDE belongs to bromide fire retardant, poisonous many bromos dibenzodioxin alkane (D B D O) and PBDF (D B D F) is not produced when its thermal cracking or burning, the environmental requirement that fire-retardant material meets American-European countries is done with it, and its Heat stability is good, anti-ultraviolet property is good, exudative low compared with other fire retardants; N, N'-piperazine four phenoxy urethane phosphate is a kind of nitrogen phosphorus flame retardant, has significant flame retardant effect, both is combined, not only make flame retardant effect high, and flame retardant effect is lasting, does not have again great impact to the mechanical property of filter paper;
6. each cost of material of the present invention is reasonable, and production technology is simple, be convenient to control, and is beneficial to and promotes the use of.
