Description
Technical field
The present invention relates to reduce the finishing agent of seat harness friction, it not only can be applied to seat harness in the spinning stage uses on the silk, and can be applied on the seat harness braid over braid.More particularly, the present invention relates to a kind of antifriction finishing agent, the safety belt after using can stretch smoothly, durable, even and still can keep good nerve after the wearing and tearing.
Technical background
Seat harness braid over braid common way after being made into and dyeing is at its surface application resinous coat.Apply this resin-coated purpose and be and make seat harness can pull out smoothly and bounce back (but or improve its nerve).On the other hand, also the braiding seat harness is used various finishing agents with silk, for example use spin finish in spinning and stretching phase.
A known example that is used to improve the coating resin of seat harness ABRASION RESISTANCE is that main component is the resin of urethane prepolymer (block copolymer).(Japanese patent gazette 66948/1992) on paint seat harness braid over braid after, this coating resin is through heat-treated, so that take place crosslinked.Originally this crosslinked resin can provide good sliding capability, even and still can keep this performance to a certain extent after long-term the use.
Seat harness is that a kind of mixture of mainly being made up of branched-chain alcoho, high-grade aliphatic ester and non-ionic surface active agent (the oxygen-free propylene) for example is disclosed in the Japanese patent gazette 175966/1990 with a known example of the conventional process agent of silk.Preceding two kinds of compositions play smooth agent, and then a kind of product of then giving is with light resistance.
Unfortunately, this resinoid coating seat harness especially has been coated with the sort of of crosslinked resin, exists the long-term shortcoming of using its face coat hardening of back.Stiff face coat resin is because the safety belt guide that is supporting nylon scouring and coming off gradually repeatedly.The surface of belt in addition, of long duration can be dirty.Sending out the dirty in addition seat harness that just makes of deadlock can't pull out and bounce back smoothly.
Under the situation that seat harness employing spin dyeing silk is made, the staining procedure of seat harness braid over braid has just no longer needed.So, once attempted in many ways again finishing resin-coated (with antifriction) in the throwing stage, so that realize not only not needing to dye, and remove its resin-coated step to being made into later seat harness braid over braid.Yet the conventional coatings resin that is used for antifriction is thickness very, if so that silk has been used this kind resin, be difficult to its from the spinning cake package smoothly unwinding get off.In addition, the coating resin that is applied on the silk also can produce disintegrating slag in the ribbon stage.So above-mentioned various trials are not succeedd so far.
Can be with the seat harness that the resinous coat silk is made without follow-up resin-coated step directly for using.The sliding of such seat harness can not reduce rapidly because of resin wear.Yet it can't fully reduce fiber to the friction to metal of fiber or fiber.Therefore, its initial sliding and ABRASION RESISTANCE are too poor, so that do not obtain practical application as yet.
The present invention will solve above-mentioned variety of problems related in the conventional art.An object of the present invention is to provide and to be applied to the seat harness silk, also can be used for the antifriction finishing agent of seat harness braid over braid.This antifriction finishing agent can reduce the coefficient of friction of the silk that constitutes seat harness, and operational phase is just very smooth in the early stage thereby make this seat harness.Moreover, it can also keep its good sliding properties in long-term use.This antifriction finishing agent can make seat harness accomplish to keep its good nerve and ABRASION RESISTANCE in long-term the use.
Another object of the present invention provides seat harness antifriction finishing agent, and it is applicable to the situation of the not dyed and RESIN FINISH of seat harness braid over braid.
Summary of the invention
The present invention relates to a kind of finishing agent, it is administered on seat harness silk and/or the seat harness braid over braid, can reduce the friction of seat harness.This finishing agent is characterised in that, it contains the polyether polyester that mean molecule quantity is 2000～15000, is made by PTMEG and aliphatic carboxylic acid.
Owing to contain this specific polyether polyester, antifriction finishing agent of the present invention is easy to be penetrated into the inside of seat harness strand, and cover monofilament surface (when being applied to the seat harness silk) in every rhizoid bar equably, perhaps, not only cover the surface of each monofilament in the seat harness, and cover the surface (when being applied to the seat harness braid over braid) of seat harness equably.
Therefore, different with the traditional Chinese chair safety belt of surface coated resin, finishing agent of the present invention can not form the double-layer structural of being made up of band (fiber) layer and resin bed.In other words, even after being worn away because of long-term use rear surface fiber, the internal fiber surface is still keeping finishing agent, therefore makes seat harness still possess for reaching the necessary low frictional behavior of good nerve.In addition, treated seat harness can also keep good ABRASION RESISTANCE.
Implement optimal mode of the present invention
According to the present invention, necessary is, the polyether polyester that this finishing agent uses a kind of mean molecule quantity to be 2000～15000, to be made by PTMEG and aliphatic carboxylic acid.
This polyether polyester should possess the mean molecule quantity of stipulating above, so that make it to possess the ability of good sliding properties and infiltration strand and braid over braid inside.When mean molecule quantity less than 2000 the time, polyether polyester can not possess the sliding properties of expection because film-strength is not enough.When mean molecule quantity greater than 15000 the time, then because friction reducing effect is insufficient, it does not possess the sliding properties of expection yet.Preferred mean molecule quantity is between 3000～10000.
This polyether polyester preferably should be: the two ends of its molecule are by the unary fatty acid end-blocking, so a kind of compound of preparation for example: with the two ends esterification of a kind of polyethers (it is described to see below) with dicarboxylic acids, and then with unary fatty acid with the further esterification in its two ends.
As a kind of composition of this polyether polyester, the mean molecule quantity of above-mentioned polyethers preferably should be 600～6000.It comprises the polymer of ethylene oxide and/or propylene oxide and gathers 1, the 4-butanediol.The latter is preferred.If its mean molecule quantity is less than 600, the finishing agent that obtains is because film-strength deficiency and sliding properties is poor.If its mean molecule quantity is greater than 6000, sliding properties is also very poor because friction is excessive for the finishing agent that then obtains.Preferred mean molecule quantity is between 800～4000.
It is to be noted that in passing mean molecule quantity used in the present invention is meant the number-average molecular weight that records with gel permeation chromatography (GPC).
Carboxylic acid as the another kind of composition of this polyether polyester should be an aliphatic carboxylic acid.At binary acid and monoacid and be used as under the situation of this carboxylic acid, at least a in the two, perhaps preferably, the two is aliphatic carboxylic acid.Every carboxylic acid that contains circulus (for example aromatic ring) is undesirable, because the polyether polyester that is generated does not possess desired low frictional behavior.
Binary acid as a kind of composition of polyether polyester comprises maleic acid, adipic acid, sulfurous base dipropionic acid and decanedioic acid.Next 3 kinds is preferred.
Unary fatty acid comprises, for example sad, laurate, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, castor oil acid, linoleic acid and linolenic acid.In these examples, laurate, isostearic acid and oleic acid are preferred.
This polyether polyester preferably should be, (20～25 ℃) person that can remain liquid at normal temperatures, so that make the seat harness handled at normal temperatures, promptly under its serviceability temperature, unlikely becoming is clamminess, but demonstrates satisfied low friction performance.
Wish that above-mentioned polyether polyester accounts for 30～100% (weight) of finishing agent total amount.Can use more than one polyether polyester.When content is less than 30% (weight), this polyether polyester will can not brought into play its expected effect.Satisfied consumption is 40～100% (weight), even so that make seat harness possess good sliding capability and still can keep good sliding properties after wearing and tearing.
Antifriction finishing agent of the present invention preferably also should contain silicone compounds (B) and/or extreme pressure additive (D) except containing polyether polyester.And it also can contain lubricant (C) and surfactant (E) in addition.The total amount of these supplementary elements preferably should be less than 70% (weight).
Silicone compounds (B) comprises, for example dimethyl silicone polymer and PSI, and modified silicone (for example with amino, polyethers, carboxyl or alkyl-modified those), and the viscosity under its 25 ℃ all should be in 100～10000cSt scope.Preferred example is 25 ℃ of dimethyl silicone polymer and amino modified silicone that following viscosity is 200～7000cSt.
The content of silicone compounds (B) should be 2～50% (weight) of finishing agent, is preferably 5～35% (weight).When content is less than 2% (weight), can not give full play of the effect of silicone compounds, so that low temperature (for example-20 ℃ the severe winter) sliding capability and the nerve of the seat harness of handling are poor.When content is higher than 50% (weight), silicone compounds will hinder giving full play to of polyether polyester effect, the frictional behaviour that the result is low owing to film-strength and wearing and tearing back sliding properties difference can not get wishing.
Lubricant (C) comprises, for example mineral oil (as refining bobbin oil and liquid paraffin), vegetable oil (as coconut oil and castor oil), fatty acid ester (as laurate isooctadecane ester, oleyl oleate and adipic acid two greases), alkyl ether acetate (as the laurate of laruyl alcohol and ethylene oxide (2 moles) addition compound product and the laurate of tridecanol and ethylene oxide (3 moles) addition compound product) and wax.In these examples, fatty acid ester and alkyl ether acetate are preferred.
The consumption of lubricant (C) should be 5～30% (weight), is preferably 10～20% (weight).
Extreme pressure additive (D) can improve the film-strength of finishing agent.It comprises, for example fatty acid soaps (as oleate soap and erucic acid soap), organic phosphate (as lauryl potassium phosphate and oil base sodium phosphate) and organic sulfonate (as neopelex).
The consumption of extreme pressure additive (D) should be 0.02～10% (weight), is preferably 1～5% (weight).When consumption is less than 0.02% (weight), extreme pressure additive can not be given full play to its effect that improves film-strength.When consumption during, because viscosity increased and the sliding properties of finishing agent is had negative effect greater than 10% (weight).
Surfactant (E) comprises, the for example alkylene oxide addition compound product of higher alcohol (as the ethylene oxide-propylene addition compound product of octanol, the ethylene oxide-propylene addition compound product of octadecanol and the ethylene oxide addition compound product of oleyl alcohol), and the alkylene oxide addition compound product of polyol ester (as ethylene oxide (25 moles) addition compound product of hardened castor oil and ethylene oxide (20 moles) addition compound product of sorbitol olein).
The consumption of surfactant should be 5～20% (weight), is preferably 10～15% (weight).
Antifriction finishing agent of the present invention also can contain optional additive except that containing mentioned component, for example the alkylene oxide addition compound product of alkali metal, alkylamine (as the pH regulator agent), antioxidant, UV absorbers and fluorine compounds.
The consumption of pH regulator agent should be 0.02～10% (weight), is preferably 0.03～8% (weight).The total amount of other additives should be 0.02～10% (weight), is preferably 0.03～5% (weight).
When being used for seat harness silk and seat harness braid over braid, the type of service of antifriction finishing agent of the present invention preferably should be the aqueous emulsion of 1～20% (weight).The concentration of this emulsion can be higher than the scope of stipulating above, as long as this emulsion can be adhered to and infiltrate in strand and the braid over braid and be gone.This emulsion can directly be used or same as before with using behind the organic solvent diluting.The aqueous emulsion of preferred 2～10% (weight).
This 2～10% (weight) aqueous emulsion preferably surface tension under 25 ℃ is lower than 35 dynes per centimeter, and the canvas osmotic value under 25 ℃ is less than 15 seconds.These conditions are to guaranteeing emulsion and adhere to satisfactorily and infiltrating strand and braid over braid is necessary.When surface tension was higher than 35 dynes per centimeter, emulsion can not be satisfactorily attached on strand and the braid over braid.When the canvas osmotic value surpassed 15 seconds, emulsion was not easy to penetrate into strand and braid over braid inside, thereby but makes the seat harness that draws can not keep its nerve for a long time.
Antifriction finishing agent of the present invention can aqueous emulsion form in the throwing process on the paint seat harness silk, perhaps paint seat braid over braid gets on.
For example, can be in the throwing process after the heat treatment, (at this moment, spun synthetic fiber have stood orientation and heat treatment) is with on this antifriction finishing agent paint strand before the coiling.In this case, the antifriction finishing agent can be used as a kind of spinning oil and uses, as long as undrawn yarn can be with the requested number finish.Oiling of seat harness silk can (or before weaving) be carried out after reeling; Yet, oil before preferably in the throwing process, facing coiling.Oiling of strand can be finished by oiling roller or thread guide.
Applying finishing agent to braid over braid (being formed through weaving by the seat harness silk) can be by being immersed in braid over braid in the corresponding solution, or finishes at this solution of braid over braid surface spraying.Dyeing if desired, then this applies preferably and carries out after dyeing.
The applied amounts of finishing agent should be 0.05～5.0% (weight) (pressing the proportional meter of active component to silk).Preferred applied amounts is 0.2～2.0% (weight) under the situation that strand is applied, and next in the situation that braid over braid is applied be 0.1～1.5% (weight).
But on the antifriction finishing agent paint strand of the present invention or on the paint braid over braid, so that give the low frictional behavior of seat harness to require.Like this, just removed from as desired resin-coated necessity in the prior art.
Antifriction finishing agent of the present invention is far away from traditional resinous coat on length of penetration.Therefore, it can be penetrated into the inside of strand and braid over braid dearly, so that its surface that can either cover the seat harness braid over braid equably can cover the surface of the silk in the seat harness braid over braid again.In other words, be different from and only carry out resin-coated traditional Chinese chair safety belt on the belt surface, safety belt of the present invention can not form double-layer structural (being made up of belt (fiber) layer and resin bed).Even so just provide because of after the interior fiber of its belt superficial layer of use is ground off for a long time, inner layer is still keeping finishing agent, thereby can keep the superiority of its low frictional behavior.So this kind seat harness is always keeping good nerve and ABRASION RESISTANCE.
The seat harness silk and the braid over braid that have applied antifriction finishing agent of the present invention are to use the synthetic fiber such as polyester fiber to make.
This strand and braid over braid can be fibrous by spin dyeing.The spin dyeing fiber can adopt common mode, is made by the resin that has added such as pigment such as carbon black, phthalocyanine blue and oxidation be red.
Be why but antifriction finishing agent of the present invention can be provided at the possible cause that nerve (sliding capability) and ABRASION RESISTANCE after the long-term use all are better than the conventional security band to seat harness below.
The sliding capability of traditional Chinese chair safety belt is the resinous coat of being made up of urethanes block prepolymer by mainly improved (referring to Japanese patent gazette 66948/1992).The problem that this prior art exists is that the resin bed that is coating the belt surface after using repeatedly can peel off the extreme difference (as mentioned above) so the sliding capability of this seat harness just becomes.Even such a case can occur: the resin that peels off forms chip, and its sliding capability has further been worsened on the surface of the belt of making dirty.In order to address this problem, once carried out many new resins that are intended to develop excellent in abrasion resistance, and the trial of thickening resin coating.Yet, do not obtain satisfied result so far.
On the contrary, the starting point of the present invention is placed on the surface of desirable sliding capability being given each monofilament that constitutes safety belt, rather than by resinous coat.
Under the situation of traditional Chinese chair safety belt, resinous coat mainly is the surface attached to belt, and only has the sub-fraction resin to infiltrate its inside.In other words, coating resin can not reach and the monofilament surface of belt innermost layer.This point can be by disintegrating belt, and the material composition of analyzing its fiber surface then is confirmed.
The superficial layer that antifriction finishing agent of the present invention not only sees through belt infiltrates, and is deep into its innermost layer, thereby has covered the numerous monofilament surface that constitute the belt innermost layer.Just in this, the present invention is far different in prior art.
The viscosity of conventional coatings resin that is used for seat harness is too high, if so that in the process of throwing, its paint seat harness silk is got on, will make strand be difficult to from the spinning cake package unwinding and get off.In addition, the coating resin on the paint strand also can produce chip, and this will make troubles to the ribbon process.
On the contrary, finishing agent of the present invention thickness unlike traditional Chinese chair safety belt coating resin then; Therefore, it can significantly not change the surface characteristic of strand, winds up straight even be applied to the strand that also will handle on the strand in the throwing process.Consequently, strand is easy to unwinding from the spinning cake package, also can not give ribbon technology because of chip and make troubles, so the ribbon process can successfully be carried out.
Strand is applied this finishing agent can remove necessity that resin-coated operation is set from the manufacture process of seat harness, yet the seat harness such as superperformances such as nerve and durability but is provided.This method effect is especially remarkable under being used in by the situation of spin dyeing silk production seat harness (promptly not dyed).
It is to be noted that in passing the dyeing of seat harness braid over braid allows to dye the tone more shallow than spin dyeing silk, and in this case, preferably with on the braid over braid after this finishing agent paint dyeing.
The front is mentioned, and antifriction finishing agent of the present invention can be applicable to any one production stage from throwing to the ribbon.No matter in which stage use, it can both give seat harness with good performance, but for example good nerve and durability.
Embodiment
Among below the embodiment and Comparative Examples, estimate every performance according to following method.
Fiber is to fibre frictoin: adopt the laser type frictiograph that the coefficient of friction between the fiber of the seat harness silk that applied finishing agent is measured.Friction co-efficient value is low more, and the frictional force between the fiber is more little, and the seat harness of making is on sliding capability thereby just excellent more.
Fiber is to metal friction: be similar to top situation, adopt Dong Lishi high load capacity micrometer that the fiber of the seat harness strand that applied finishing agent is measured the coefficient of friction between the metal, fiber is supporting the metal surface scouring with the speed of 0.5 meter/minute or 300 meters/minute.Frictional force under 0.5 meter/minute scouring speed is represented film-strength, and the frictional force under 300 meters/minute scouring speed is represented flatness.This value is low more, and flatness is good more.
Treatment fluid surface tension (dynes per centimeter): adopt automatic surface tensiometer (model is CBVP-A3, is made by Kyowa Kaimen Kagaku company) to measure down at 25 ℃.
Treatment fluid canvas infiltration (second): the treatment fluid sample is placed 100 ml beakers, make it in 25 constant temperature bath, place 15 minutes.On the sample liquid level, put a slice felt (2 ' 2 ' 3mm are thick) gently, measure felt and sink the needed time (second).The result represents with the mean value of 5 mensuration.
Sliding friction (%) to guide: the end at sample adds 500 kilograms weight and adorns 10 kilograms of load sensors at the other end of sample.Sample is under the situation at 20 ° of angles by a guide bending in the middle, and load sensor is applied a power, and weight is upwards drawn.Note first power (F1) that weight is upwards drawn, and second power (F2) that in weight decline process, stops this weight, the square root of sliding friction (%) usefulness (F2/F1) is multiplied by 100 and represents.Sliding friction numerical value is big more, and frictional behavior is good more, but thereby nerve good more.
Sliding friction after the wearing and tearing (%): with a slice sand paper (No. 500) sanding block seat belt sample 500 times under 400 gram loadings.By measuring the sliding friction (%) of the sample that ground with top identical method.
Strength retention (%) after six rib rod millings are decreased: measure the intensity of seat harness sample after wearing and tearing (5000 circulations) according to JIS-4604 (abrasion test), wearing and tearing back intensity is strength retention to likening to of intensity before wearing and tearing.
