Described ptfe emulsion solid content is 30-45%；Polyacrylate dispersion solid content is 30-50%；Dilute sulfuric acid concentration For 30-50%；Colophonium alcoholic solution solid content is 50-70%；The wollastonite of raphioid fiber crystal structure selected by wollastonite.
Mineral fibres filling-foam stone corrugating media of described a kind of cracking resistance and preparation method thereof, by following steps Make:
A. kieselguhr is added stirring acidifying 2-3h in dilute sulfuric acid, then filters, after drying, by the kieselguhr obtained, silicon ash Stone, calcium carbonate and Colophonium alcoholic solution send into fluidized-bed reactor, set fluidized-bed reactor temperature as 40-70 DEG C, by sky Wollastonite, calcium carbonate, kieselguhr are suspended among the fluid of motion by gas, so that acicular wollastonite is interspersed in diatomaceous micro- Hole, its gap calcium carbonate-filled, make three be formed by the effect of Colophonium and there is the compound particles of fibrous-network structure, and Colophonium is had to wrap up；
B., at 80-140 DEG C, azodicarbonamide, dodecyl sodium sulfate are joined in polyethylene, adds polyoxygenated Ethylene, stirs in blender, is subsequently adding step a gained compound particles and nylon fiber, proceeds to after mix homogeneously Single screw extrusion machine, extrudes prefoam paper membrane, by controlling carry-over pinch rolls, prefoam paper membrane carries out the longitudinal stretching of about 2 times, Foamed by pre-hot-rolling and hot-pressing roller, thus obtain microcellular foam material；
C. by Mg (OH)2Join in ethanol, after ultrasonic disperse system high speed dispersion 50-100 min, regulate ultrasonic temperature Degree, for 40-70 DEG C, adds polyacrylate dispersion, high speed dispersion 70-130 min, obtains Mg (OH)2Suspension, through sucking filtration, baking Dry, pulverizing obtains the modified Mg (OH) of powder2；
D. by powdered modified for step c gained Mg (OH)2Join in ptfe emulsion, add paraffin, stir, Make fireproof coating and be applied to step b gained microcellular foam material surface, be then processed to form the foaming of waveform by corrugated roller Stone corrugating media.
Mineral fibres filling-foam stone corrugating media of described a kind of cracking resistance and preparation method thereof, its feature exists In, extruder temperature controls at 150-180 DEG C, and the temperature of pre-hot-rolling controls at 130-160 DEG C, and the temperature of hot-pressing roller controls 160-220℃。
The invention has the beneficial effects as follows: interspersed being connected with diatomaceous by acicular wollastonite, calcium carbonate fills up its space, Ensure that the space structure of fiber, the kieselguhr of almost spherical has elastic buffer, makes stone corrugating media have fibrous web-like Supportive and condrapable nature, be simultaneously introduced Colophonium, is possible not only to promote that acicular wollastonite, kieselguhr are netted with what calcium carbonate was formed The holding of space structure, and be conducive to its dispersion in polyethylene and fusion；Add azodicarbonamide foaming agent and ten Dialkyl sulfonates so as to get stone corrugating media have that pore is the finest and closely woven, the feature of light weight, facilitate the fortune after packaging Defeated, save the energy；Use polyacrylate dispersion modified magnesium hydroxide, improve its dispersibility in ptfe emulsion and Stability, is coated stone corrugating media by this emulsion, improves its water proof fire retardant, moisture-proof, antibiotic so that it is can be more Good is applied to packaging field；By the addition of polyethylene glycol oxide, improve the performance of corrugating media cracking resistance.
