The a lot of regional day and night temperature of China is large, larger day and night temperature can cause highway pavement to occur crack because expanding with heat and contract with cold, generally ambient air temperature change greatly, day and night temperature is larger, cement concrete shrinks will be more serious, and cement concrete contraction can produce great tensile stress, when the tension stress of cement concrete is once exceed cement concrete ultimate tensile strength at that time, plate just produces transverse breakage behind crack, causes very large damage to highway pavement.If concrete moisture-keeping functions in highway cement concrete, the heat energy that the moisture Absorbable rod part daylight wherein contained produces also regulates nocturnal temperature, make road surface day and night temperature reduction of maintaining public highway, thus effectively reduce the problem because the temperature difference causes greatly cement concrete to shrink.
Current highway maintenance geotextiles only has waterproof and insulation effect, does not possess moisture-keeping functions, therefore market is badly in need of a kind of highway maintenance Geotextile Products with moisture-keeping functions.
Summary of the invention
The invention provides a kind of production technology of highway maintenance moisturizing geotextiles, to solve the problem that existing highway maintenance geotextiles does not possess moisture-keeping functions.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of production technology of highway maintenance moisturizing geotextiles, take polyester staple fiber as raw material, after opening or cleaning, combing and lapping, on the fiber web formed, humectant is spread at stand, then form through pre-needling, drawing-off, main acupuncture, main acupuncture and trimming, concrete technology step is as follows:
(1) opening or cleaning: polyester staple fiber is carried out shredding, removal of impurities and mixing, then delivers to storage bin;
(2) combing: polyester staple fiber clump, is loosened as single state to carding machine by skewed slot feeding by the polyester staple fiber in storage bin, makes fiber alignment just tool direction, removing impurity and fault, and makes ribbon;
(3) lapping: ribbon is formed more uniform fiber web through lapping machine laying together;
(4) humectant is added: humectant is spread at stand on the fiber web formed, and it is 50-400 gram/m that density is spread at the stand of humectant;
(5) pre-needling: needing machine stings in advance to fiber web, to reduce fibroreticulate volume, then carries out drawing-off to fiber web;
(6) main acupuncture: by pricker to fibroreticulate reversal puncture, brings the fiber at the fiber web back side into fibre web inside, adds the entanglement of fiber, and the fibre web brute force through pre-needling is improved;
(7) main acupuncture: the fiber web tentatively tangled through pre-needling and main acupuncture is tangled by the further acupuncture of main needing machine, reaches entanglement effect and the needling density of the requirement of moisturizing Geotextile Products, then trimming is carried out to moisturizing geotextiles;
(8) put in storage: the moisturizing geotextiles after trimming carries out measurement deciding grade and level through inspection, then metering packing, warehouse-in.
The humectant that present invention process uses is polyacrylamide humectant, its main component is acrylamide, potassium acrylate, water and crosslinking agent, wherein the mass content of acrylamide is 65% ~ 66%, the mass content of potassium acrylate is 23% ~ 24%, quality content is 8% ~ 10%, and crosslinking agent mass content is 0.5% ~ 1.0%.
In the moisturizing geotextiles that present invention process is made, humectant can absorb suitable own wt and becomes the water of hundred times. and water retention agent can effectively suppress moisture to evaporate. after infiltrating water retention agent in soil, moisture is inhibit to evaporate to a great extent, improve the moisture of appended object, thus slow down the speed of release water, reduce infiltration and the loss of moisture, reach the object of water conservation.The moisture that geotextiles contains can the heat energy that produces of retaining part daylight regulate nocturnal temperature, and the road surface day and night temperature that makes to maintain public highway reduces, and solves highway pavement because of the temperature difference to cause greatly cement concrete to shrink the problem causing fracture
