The process has the advantages that the product can absorb oil which exceeds 10-20 times that of deadweight of the product.

Description

The manufacturing process of powerful anti-stab oil suction carpet

Technical field

The present invention relates to a kind of nonwoven carpet that adsorbs oils.

Background technology

Adsorption cotton is that oil product and chemical leakage spill and leakage spatter after leakage, dispose the most frequently used article that arrive of leakage, but, the marine pollution causing for all kinds of acidity (comprising hydrofluoric acid), alkaline hazardous chemical, non-corrosive liquid and marine extensive oil spill accident, does not still have effective, succinct removing way.

Summary of the invention

For solving foregoing problems, the invention provides the manufacturing process of the anti-stab oil suction carpet of a kind of brute force, the manufacturing process of the anti-stab oil suction carpet of this brute force is:

(1) polypropylene is made melt spraying non-woven fabrics by melt-blown process;

(2) polypropylene, by spunbond process, is made spun-bonded non-woven fabrics;

(3) melt spraying non-woven fabrics and spun-bonded non-woven fabrics are superimposed as to the layer structure of three layers, three-decker is: 35 grams of/square of nonwoven sticky clothes for A layer above, and intermediate layer is 200 grams of/square of melt spraying non-woven fabrics for B layer, 15 grams of/square of nonwoven sticky clothes for lower surface layer C layer; The ratio of melt spraying non-woven fabrics and spunbond nonwoven sticky cloth is 80%:20%;

(4) three layers of nonwoven are combined with each other by high-frequency ultrasonic welding procedure;

(5), by three layers of nonwoven C layer nonwoven surface that are combined with each other, by extruding casting technique, spray thin film with polyethylene;

(6) use computer quilting technique, by three layers of nonwoven loop bonding that are combined with each other;

(7) spray at three layers of nonwoven the one side that has film layer, with full-automatic glue spraying machine, spraying one deck viscose glue, forms powerful anti-perverse asphalt felt.

Advantage of the present invention is that product of the present invention is placed on the busy passage in the ground that is stained with greasy dirt, the particularly volume of traffic, can adsorb all kinds of acidity (comprising hydrofluoric acid), alkaline hazardous chemical, makes ground passage keep clean and dry and comfortable.Can also absorb some and concentrate at ground lighter greasy dirt fog, product of the present invention on the water surface time because of not absorbing water, after absorption grease is saturated, then swim in waterborne, the adsorbable oil that exceedes dead weight 10-20 times.Can be used for the processing of mechanical greasy dirt, gutter greasy dirt, warehouse harbour greasy dirt and river greasy dirt etc., keep working environment cleaning, stop oil gas volatilization and cause an explosion accident positive effect.

The specific embodiment

Fusion-jetting polypropylene nonwoven manufacturing process is:

The manufacturing process of polypropylene (PP) adsorption cotton is first to obtain fusion-jetting polypropylene.The technical process of polypropylene melt-blown fabric nonwoven cloth is: polypropylene particles feeds → melt extrudes → fiber formation → fiber is cooling → in spinning plate, become net → reinforce into fusion-jetting polypropylene nonwoven.

Melt-blown process is:

Polypropylene 100%; Polypropylene particles feeding is squeezed molten machine thawing and is extruded, high velocity, hot air carries out drawing-off to die head spinneret orifice polypropylene fluid, form ultra-fine chemical fibre and condense upon nonwoven accepting device fiber cold-adhesion and be molded in spinning plate and become net, the non-woven nonwoven of polypropylene moulding becomes melt spraying non-woven fabrics; Parameter is as list:

Spun-bonded non-woven fabrics manufacturing process is:

Polypropylene 100% polymer adds filling container---to be extruded high-temperature fusant thing by screw extruder to the large spiral shell stalk of PP high-temperature fusion and---repeats to filter through melt pipe filter and---enter flow measurement pump and quantitatively carry PP melt thing that---suction makes PP melt become fibrous to air drawing equipment to spinning entrance up-down stretch---sub-wire lapping evenly fiber is divided to be paved into network structure cooling---by upper lower compression roller pre-reinforcement---processes and reinforce formation spun-bonded non-woven fabrics to the hot-rolling mill pressurization blanching of heating.Technological parameter is as following table.

High-frequency ultrasonic welding procedure is, adopts high-frequency ultrasonic compounding machine, is delivered to two material surfaces that nonwoven is to be welded with dither ripple, the in the situation that of pressurization, makes the mutual friction of material surface phase and forms molecular layer and fuse.Design parameter is as shown in list:

Polyethylene (PE) film manufacture craft is:

Use 100% polythene material, curtain coating compounding machine plastic pellet is extruded in employing, after spiro rod plasticizing, become line style to extrude by flat-mould head die orifice, after stretching, be attached to nonwoven flexible parent metal surface, after cooling and shaping is pressed into, have barrier and the heat sealability of plastic film layers concurrently, and the composite of the toughness characteristic of base material.

On nonwoven, make after this film, make nonwoven there is superior uniform gas permeability, effectively isolate moisture, discharge hot gas and moisture.Meanwhile, also there is flexibility, have fabulous feel, make product more soft comfortable.In addition, there is outstanding tension and the mechanical performance of extension.And not perishable, printing is simple, sun-proof high temperature.

Film technological parameter is as list:

Computer quilting technique is:

With dacron thread 100% quilting.Computer quilting function is ideally processed and on whole coordinate system, is worked out upper and lower outer spunbond cloth and fusion spray cloth with wave decorative pattern patterned ground loop bonding above straight line below side by side.

Quilter is identical with quilter principle.It is all the system with the motion of XY-Z-type.The motion of XY axle control head, the quilting of Z axis control head.

(1) Z-direction motion---the motion that quilting pin is upper and lower.

(2) X-direction motion---the head side-to-side movement of quilter.

(3) Y direction motion---the head of quilter seesaws.

Viscose glue spraying coating process:

Adopt the solvent borne of the re-posted repeatedly glue that composition is SR106.

Glue is being fallen apart and penetrated with full-automatic glue spraying machine, and making it to be attached to according to certain rules PE surface.Spraying face larger, the viscosity duration is long; Adherend can be taken off easily, and glue spraying particle is thin clean transparent, can maculose to most of materials, shrink infiltration.Powerful anti-stab oil absorbent material can be finely fixed on any condition ground, prevent that oil absorbent material is at taxiing.

Concrete technology parameter is as list:
