Technical field
The present invention relates to highway maintenance material production technical fields, and in particular to a kind of highway maintenance moisturizing geotextiles Production technology.
Background technique
Highway maintenance geotextiles are water penetration geosynthetics made of being pierced or woven by needle as synthetic fibers, extensively It is general to be applied to bituminous pavement, the enhancing of cement concrete pavement and roadbed, no matter rigid road surface and flexible pavement it is all applicable, with Conventional pav ratio can reduce cost, prolong the service life, and prevent road suface crack, easily in conjunction with bituminous pavement, with sticking layer oil In conjunction with rear formation separation layer, there is waterproof and insulation effect.
Much regional day and night temperature is big in China, and biggish day and night temperature will cause highway pavement and split because expanding with heat and contract with cold Seam, greatly, day and night temperature is bigger for ambient air temperature variation under normal circumstances, and cement concrete contraction will be more serious, cement concrete Contraction can generate great tensile stress, when the tension stress of cement concrete is once more than that the limit of cement concrete at that time is anti- When tensile strength, plate just generates transverse breakage behind crack, and very big damage is caused to highway pavement.If highway cement coagulation Specific moisture-keeping functions in soil make wherein the moisture contained can absorb the thermal energy that part daylight generates and adjusts nocturnal temperature The road surface day and night temperature that must maintain public highway reduce, thus be effectively reduced because the temperature difference greatly caused by cement concrete shrink the problem of.
Current highway maintenance geotextiles only have waterproof and insulation effect, do not have moisture-keeping functions, therefore anxious in the market Need a kind of highway maintenance Geotextile Products with moisture-keeping functions.
Summary of the invention
The present invention provides a kind of highway maintenance production technologies of moisturizing geotextiles, to solve existing highway maintenance geotechnique Cloth does not have the problem of moisture-keeping functions.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of production technology of highway maintenance moisturizing geotextiles, using polyester staple fiber as raw material, through opening or cleaning, combing and paving After net, on the web of formation booth spread moisturizer, then by pre-needling, drawing-off, main needle thorn, main needle pierce and trimming and At, the specific process steps are as follows:
(1) opening or cleaning: polyester staple fiber is subjected to shredding, removal of impurities and mixing, is then sent to storage bin；
(2) comb: polyester staple fiber in storage bin by skewed slot feeding to carding machine, by polyester staple fiber clump loosen for Single state makes fiber alignment just have direction, remove impurity and fault, and ribbon is made；
(3) ribbon lapping: is formed into relatively uniform web through lapping machine laying together；
(4) add moisturizer: moisturizer is spread at booth on the web of formation, the booth of moisturizer spread density be 50-400 grams/ Square metre；
(5) pre-needling: needing machine pierces web in advance, to reduce the volume of web, then carries out to web Drawing-off；
(6) the main needle that falls pierces: the reversal puncture by pricker to web brings the fiber at the web back side in fibre web into Portion increases the entanglement of fiber, improves the fibre web strength by pre-needling；
(7) web tentatively to tangle by pre-needling and main needle thorn main needle thorn: is passed through into the further needle of main needing machine Thorn tangles, and reaches the entanglement effect and needling density of moisturizing Geotextile Products requirement, then carries out trimming to moisturizing geotextiles；
(8) be put in storage: the moisturizing geotextiles after trimming measure deciding grade and level by inspection, then metering packing, storage.
The moisturizer that present invention process uses is polyacrylamide moisturizer, and main component is acrylamide, propylene Sour potassium, water and crosslinking agent, wherein the mass content of acrylamide is 65% ~ 66%, and the mass content of potassium acrylate is 23% ~ 24%, Water quality content is 8% ~ 10%, and crosslinking agent quality content is 0.5% ~ 1.0%.
Moisturizer can absorb suitable own wt into hundred times of water water-retaining agent in moisturizing geotextiles made of present invention process It can be effectively suppressed after penetrating into water-retaining agent in moisture evaporation soil, largely moisture inhibited to evaporate, improve appended object Water content, thus slow down release water speed, reduce the infiltration and loss of moisture, achieve the purpose that water conservation.Geotextiles contain Some moisture can holding part daylight generate thermal energy and adjust nocturnal temperature so that road surface day and night temperature of maintaining public highway subtracts It is small, solve the problems, such as highway pavement because the temperature difference greatly caused by cement concrete contraction cause fracture
Acrylic amide moisturizer is creatively added in the web of polyester staple fiber formation by present invention process, real Showed the performance of keeping humidity of highway maintenance geotextiles, easily in conjunction with bituminous pavement, in conjunction with sticking layer oil after form separation layer, can It is widely used in bituminous pavement, the enhancing protection and maintenance of cement concrete pavement and roadbed.
