Fig. 1 is a process flow diagram of the present invention
The specific embodiment
The anti-near infrared ray dacron tarpaulin of ventilating, antiflame, oilproof, waterproof, acidproof acid-proof is a kind of multifunctional protection fabric of regulation fibrous material.The safeguard function of its core is anti-flammability and grease-proof and waterproof acid-proof performance, and fire-retardant processing is that Fen Erdao carries out (coating behind the first base cloth).The fire-retardant phosphorus halogenated flame retardant that all uses of the durable flame-retardant finishing of base cloth and coating, fluorochemical is used in the anti-acid treatment of grease-proof and waterproof, and the phosphorus halogen fire retardant just has similar synergistic effect with fluorine-containing antacid like this.The solution of saturating vapour (wetting) is modification and the single face coating that refers to by PU coating tree, anti-near infrared ray is to add suitable dyestuff in PU coating slurry, and, make it both reach anti-infrared requirement to the reasonably adjustment of prescription do that flame retardant coating is starched, do not reduce the anti-flammability of product again.
1, the durable flame-retardant finishing of polyester canvas: the classical way of polyster fibre and fabrics flame resistance processing is to add fire retardant (copoly type and addition type), elder generation's production flame-resistant terylene resin, respin a silk acquisition fire resistance fibre and a flame-retardant textile in terylene macromolecule resin polymerization process; Also can when the polyester resin spinning, add the fire retardant master batch in addition and produce fire resistance fibre and flame-retardant textile.The great advantage of this method is that the durability of fire-retardant (washability) of fiber and fabric is good.Be convenient to large-scale production, cost is lower; But this method also has its defective: the one, and the anti-flammability of fiber and fabric is not too high, and general LOI is 27-28, if the fire retardant consumption is excessive, then has influence on the proper property (brute force, elongation, hot property etc.) of spinning moulding and polyster fibre; The 2nd, this method is difficult to adapt to the commodity production of many kinds small number.
With annular phosphate dacron is carried out durable flame-retardant finishing.With the annular phosphate of ground productions such as Shanghai, Zhejiang, Shandong, Taiwan with roll roasting technology and high-temperature pressure dyeing with two kinds of methods of bath process to pure terylene woven fabric (250g/m
2) carried out the flame-proof treatment test, the results are shown in Table 1.
The pure dacron main performance of table 1 annular phosphate arrangement
| Technology type | Fabric weightening finish % | The anti-flammability measured value | The GB8965-1998 regulation | |||||
| Do not wash | 50 ℃ of hot water wash 10 minutes | Afterflame s | S glows | Decrease long mm | Afterflame s | S glows | Decrease long mm | |
| Pad and bake | 15.9 | 1.59 | 9.23 | 0.42 | 90 | ≤5 | ≤5 | ≤150 |
| High-temperature pressure dyeing is with bathing | 30.5 | 1.34 | 13.07 | 0 | 90 | |||
Annotate: fabric is 250g/m
2Pure terylene woven fabric; After the anti-flammability measured value is the sample washing.
As can be seen from Table 1: the weightening finish before two kinds of flame-retardant textiles are not washed is respectively 15.99% and 30.58%, and hot water wash increases weight after 10 minutes and reduces to 1.59% and 1.34% respectively, and explanation is not laundry-resistant.The after flame time of washing back sample also was respectively 9.23 seconds and 13.07 seconds, did not all reach the regulation of national standard≤5 second.
The durable flame-retardant arrangement bromine Sb system fire retardant commonly used of dacron, when the fabric high-temperature pressure dyeing, bathe flame-proof treatment together, the flame-resistant terylene fabric washability that this method is produced is good, anti-flammability can be according to customer requirements levelling height, fabrics feel soft, and production technology is easy, but the greatest problem of this method is that bath raio is too big in the production process, the continuous cylinder of fire retardant is added with certain limit, and the serialization degree is low, and production cost is higher.
The present invention adopts the bromine Sb system fire retardant, to roll the roasting continuous processing polyester canvas is carried out durable flame-retardant finishing, has obtained good result.
(1) fire retardant concentration is to the influence of fabric weightening finish and anti-flammability.
The consumption of fire retardant directly has influence on the weightening finish and the anti-flammability of fabric.Table 2 provides the variation with the fire retardant working concentration of fabric weightening finish and anti-flammability.
The relation of the performance of table 2 finish fabric and fire retardant consumption
Annotate: fabric specification is 20S/2*20S/2 60*36
As can be seen from Table 2: along with the increase that fire retardant uses, the weightening finish of finish fabric raises, and char length reduces, and anti-flammability increases; Table 2 data declaration: just along with the increase of fire retardant consumption, eluting rate reduces, and the application efficiency of fire retardant improves.In the fire retardant working concentration scope of being tested (60-90%), the char length of finish fabric is all less than 100mm, and after flame time is all less than 3 seconds, and the time of glowing all meets the technical requirements all less than 5 seconds.Because the difference of fusion drip phenomenon, its anti-flammability was difficult to estimate when pure dacron was met fire burns, but after fire retardant canvas applied coating, the molten drop phenomenon disappeared substantially, the difference of base cloth anti-flammability is just fairly obvious.Fire-retardant and fire-retardant uniformity and the synergistic of coating in order to ensure base cloth, comparatively desirable during fire retardant concentration 60-90%.
(2) washability of crosslinked resin and flame-retardant textile
The chemical constitution of ring-type bromide fire retardant is very similar to the phenyl ring in the terylene macromolecule, when reaching the second order transition temperature of polyester resin, (be deformed to the viscous state distortion) by elastomeric state, the circulus of bromide fire retardant can embed in the middle of the phenyl ring long-chain of polyester macromolecule, and form an integral body, this is the high temperature set principle of ring-type bromide fire retardant to pure dacron arrangement, it also is the major technique approach that improves the flame-retardant textile washability, yet evidence: an amount of cross linking agent not only can improve the smooth property of flame-retardant textile feel, also can improve the washability of flame-retardant textile.Table 3 has provided crosslinked resin to the feel of finish fabric and the influence of eluting rate,
Table 3 crosslinked resin is to the influence of finish fabric feel and eluting rate
Annotate: the working concentration of fire retardant is X%; Fabric construction is 20S/2*20S/2 60*36.Relation between the working concentration of crosslinked resin and finish fabric weightening finish and the washability.
As can be seen from Table 3: in fire retardant concentration one regularly, the washability of finish fabric is along with the working concentration of crosslinking agent increases obviously raising; The weightening finish of finish fabric is also significantly risen with the working concentration of crosslinking agent.When not using crosslinking agent, fabric feeling is coarse, and working concentration is when higher (12% and 20% weight ratio), and fabric feeling is more stiffening; The dependency of the anti-flammability of finish fabric (char length) and crosslinking agent working concentration is not fairly obvious, and this mainly is fire-retardant pure dacron fusion drippage when running into flame, and makes flame stop institute extremely, and fire resistance in fact at this moment has certain illusion.The characteristics of the every index of comprehensive improvement fabric, the working concentration of crosslinking agent is more reasonable at 4-8%.
(3) bake and set
Because the ring-type bromide fire retardant is put in order pure dacron, its set principle mainly is to reach by the phase embedding effect of similar chemical constitution under the high temperature, so there are bigger influence baking temperature and time to the set degree of depth.(less than 170 ℃) substantially can not set when temperature was low, and when temperature too high (more than 200 ℃) and overlong time (more than 5 minutes), though anchor effect is fine, but fabric feeling hardening, its colour changed into yellow, the baking temperature of selecting for use in the practical application are 170-200 ℃, and the time of baking is 1-5 minute; Higher baking temperature and the long time that bakes also are favourable to the chemical interlinkage that the interlinkage tree refers to.
2, the performance of fire-retardant PU coating adhesive and coated fabric
Current coating material commonly used both at home and abroad mainly contains polyurethane (PU), polyacrylic acid resinoid (PA) and Corvic (PVC) etc.The PU coating resin is soft, any surface finish is smooth, and high and low temperature resistance is good, and the environmental factor in the production process makes use PU coating resin in the research again.
(1) four kind of PU coating adhesive fire resistance relatively
It is all far apart that the fire-retardant PU coating resin of selling on common PU coating resin and the domestic market will reach the fire-retardant index request of this project.The performance of glowing that table 4 has provided four kinds of PU coating resins compares.
Four kinds of PU coating resins of table 4 fire resistance relatively
Annotate: used fabric is the polyester canvas through durable flame-retardant finishing; Specification is 20S/2*20S/2.
As can be seen from Table 4: three kinds of coating adhesives selling on the market all do not reach requirement, have only the composite № of our company 4 flame-retardant coatings glues just can meet the fire-retardant index request of project.
(2) two kinds of fire retardants are to the coated fabric Effect on Performance
Table 5 has provided phosphorus halogenated flame retardant (№ 4) to coated fabric Effect on Performance (comprising the influence to fabric after flame time and char length).
Table 5 phosphorus halogenated flame retardant (№ 4) is to the coated fabric performance impact
Annotate: 1. fabric is the polyester canvas of durable flame-retardant finishing; Fabric specification is 20S/2*20S/2.
2. the use amount of bromide fire retardant (DS-110) is 9.0%.
Table 6 bromide fire retardant (DS-110) is to the coated fabric Effect on Performance
Annotate: 1. fabric is the polyester canvas through durable flame-retardant finishing, and specification is 20S/2*20S/2.
2. the consumption of phosphorus halogenated flame retardant is 40%.
As can be seen from Table 5: along with the increase of phosphorus halogenated flame retardant (№ 4) working concentration, char length and after flame time all reduce, reach at 45% o'clock in fire retardant concentration, char length is 60mm, after flame time 4.8s, substantially, can reach technical requirement, the concentration of fire retardant in the practicality (№ 4) is comparatively reasonable between 30-50%.
Provided at table 6: the working concentration of bromide fire retardant (DS-110) is bigger to the influence of coated fabric after flame time, reach 10% when above in concentration, after flame time all can meet index request (≤5 seconds), when but DS-110 concentration is too high (20-25%), the coating adhesive flowability is relatively poor, coating construction is difficulty, and is comparatively suitable during the concentration 9-15% of DS-110 in the practical application.
(3) the hydrostatic pressure resistant power and the anti-flammability of coating layer thickness and coated fabric
Coating layer thickness (spread) directly has influence on resistance to hydrostatic pressure power, anti-flammability, feel and other presentation quality (seeing Table 7) of coated fabric.
Table 7 spread and coated fabric performance
Annotate: fabric is the polyester canvas through durable flame-retardant finishing, and specification is 20S/2*20S/2.
As can be seen from Table 7: spread is at 54.2g/m
2When above, hydrostatic pressing, anti-flammability can both reach project indicator requirement, but its presentation quality is only at spread 76.0g/m
2Just meet the requirements when above, the too high cost that can make again of spread increases, so use 80-110g/m in the research
2Coating layer thickness.Above-mentioned coated fabric has the ability of suitable waterproof (drenching with rain), especially adopts water-based PU to have the ability of vapour.
3, grease-proof and waterproof acid-proof processing
The kind of fluorine-containing antacid and working concentration have determined the waterproof (drenching with rain) of coated fabric to a great extent, grease proofing and acid-proof performance (seeing Table 8), though fluorine-containing antacid DS-107 also has certain adhesiveness to polyster fibre, but for the attachment fastness of raising antacid on dacron by a relatively large margin, it is shared with antacid DS-107 that the present invention's use has highly active crosslinked resin (DS-202), and be equipped with appropriate catalyst, the pH value conditioning agent, bake when crosslinked at high temperature, by means of antacid, macromolecular chemical bond of crosslinking agent and polyster fibre and physical absorption can improve the fastness of grease-proof and waterproof acid-proof fabric greatly.
Table 8 antacid consumption is to the finish fabric Effect on Performance
Annotate: finish fabric is a 20S/2*20S/2 flame retardant coating polyester canvas.
Can see from table 8: antacid DS-107 working concentration was at 9% o'clock, 4 grades of waterproof (drenching with rain), grease proofing 120 minutes, sulfuric acid time of penetration 〉=30 minute, all reached project indicator requirement, though the working concentration of antacid DS-107 (202) is high more, the waterproof of finish fabric, grease proofing acid-proof performance are good more, and its processing cost is also just high more.The concentration of selecting antacid DS-107 in the research for use is in the scope of 9%-11%.
4, near infrared protection
(1) selection of infrared ray camouflage dye
The infrared ray camouflage dye is with usually dyestuff is the same, and the infrared ray absorbing dyestuff also has the electron conjugated system of specific л, be not both them first excite band be lower, absorption be not visible light, but the infrared light of longer (can reach 1500nm) of wavelength.
Dyestuff like infrared ray camouflage dye (or pigment) some infrared ray absorbing features and the spontaneous combustion environment facies of referring to.It can make painted object identical or close with environment (the present invention refers to the jungle environment) to ultrared absorption, the profile of object is disappeared or fuzzy, and difficult quilt is detected device discovery, reaches stealthy purpose.
The dyestuff that the present invention selects for use is: A, 8204 golden yellow B, 8505 black
C, 8601 green D, 8206 orange
(2) application of infrared camouflage dyestuff in fire-retardant PU coating adhesive
Four kinds of dyestuffs add in the № 4 fire-retardant PU coating adhesives of this project development with suitable amount according to a certain percentage, stir to expect directly to be coated with evenly and behind the froth breaking and invest on the fabric, drying (less than 110 ℃) and high temperature can obtain good anti-infrared effect after baking (170-200 ℃) again: the reflectivity of 700nm wave band is 33.13%, the reflectivity of 1400nm wave band is 77.82%, all meets project indicator requirement.The adding of four kinds of anti-infrared dyestuffs has certain influence to the anti-flammability of PU glue, and we can obtain the satisfactory anti-infrared coated fabric of fire resistance after the complex process of № 4 fire-retardant PU coating adhesives is adjusted slightly.
5, batch industrial production: entrust textile mills to produce more than 1000 meter of polyester canvas on request as a trial earlier, and carry out pre-treatment.Carry out the polyester canvas durable flame-retardant finishing then, do fire-retardant anti-infrared PU coating processing again, do the batch industrial production of the anti-acid treatment of grease-proof and waterproof at last, yield rate reaches more than 90%, and product colour is that national defence is green.

The main performance index of the anti-near infrared ray polyester canvas of ventilating, antiflame, oilproof, waterproof, acidproof acid-proof is listed in table 9.
The main performance of saturating vapour (wetting) the property five anti-dacron tarpaulins of table 9
Annotate: fabric is a polyester canvas: 20S/2 * 20S/2 60*36.
Data by table 9 can be seen: by the selection of technology path, the research of complex function compatible technique, the durable flame-retardant finishing of polyester canvas, coating fire-retardant, anti-near infrared prescription and engineer testing, industrial production and Performance Detection prove in batches: the research that the ventilating, antiflame, oilproof, waterproof, acidproof acid-proof is put near infrared ray terylene paulin and manufacture method thereof has reached the requirement of project technical indicator.
6, with the comparison of similar products at home and abroad:
From the document that we have found, the report of domestic and international same or similar product seldom.There is one piece of similar report 2002 the 5th phases of " printing and dyeing " magazine, though it is very big with the technology used in the present invention route and envelop of function difference, but the key technical indexes are done one relatively.
Two kinds of multifunctional terylene paulins of table 10 major function relatively
As can be seen from Table 10: (1) except that fire-retardant, waterproof, saturating vapour (wetting) index, grease proofing, acid-proof, anti-infrared also be main contents of the present invention, and the multifunctional terylene paulin of Tianjin does not possess this three kinds of functions.(2) duration of fire resistance of Tianjin product is 7.8 seconds, has exceeded the regulation of multiple index, also exceed this project specifies＜=5 seconds, undesirable.(3) ultimate strength of Tianjin product is higher, and this mainly is that the yarn count and the density of two kinds of base cloths that product uses is different.(4) technology path of Tianjin production is that base cloth is done non-washable fire-retardant processing earlier, and both sides are coated with not fire-retardant PA coating again, and its shortcoming is: if the both sides coating is discontinuous, fire retardant can moltenly drift out after meeting water, influences the anti-flammability of paulin; If the both sides coating is thicker, make the paulin anti-flammability not reach requirement again, this product epithelium fastness of reflection is poor in the use, and the friction decortication is exactly its reason easily.
Can see in sum: the anti-infrared dacron tarpaulin of ventilating, antiflame, oilproof, waterproof, acidproof acid-proof of the present invention not only has five kinds of safeguard functions, and performance is the best, and has reached industrial production and practical requirement.
