Description
Technical field
The present invention relates to thermal insulation material technical fields, and in particular to a kind of winter road construction maintenance heat preservation felt rug.
Background technology
The construction process of road has strict demand, different environment temperatures that can influence the condensation effect of base-material temperature
In fruit, such as highway bridge and culvert engineering construction construction criteria, the out-of-machine temperature of concrete is required to cannot be below 10 DEG C, enters mould temperature
Degree cannot be below 5 DEG C, if temperature cannot reach standard, may result in the reduction of roadbed quality, and insufficient strength is easily broken,
Acceptance criteria is not achieved.
Therefore, more urgent to construction period at some, the road construction project constructed under microthermal climate in winter is needed,
Roadbed must carry out isothermal holding after being laid with.Generally use nose bag or cotton-wadded quilt etc. carry out isothermal holding during road construction,
The cost of nose bag is relatively low but heat insulation effect is relatively poor；Cotton-wadded quilt it is of high cost, heat insulation effect is good, be easy to fold recycling, but
It is that cotton-wadded quilt fireproof flame-retardant effect is poor, is difficult to put out a fire to save life and property in time if being ignited in dry winter；In addition, cotton-wadded quilt is used for multiple times
Afterwards, the fabric meeting aging on surface layer is damaged, cannot be used continuously, the recycling rate of waterused of material is relatively low.
Invention content
For problems of the prior art, is conserved the present invention provides a kind of winter road construction and uses heat preservation felt rug,
The heat-insulating property of the heat preservation felt rug protrudes, good flame retardation effect；The flexibility of material is preferable, is easy to fold or wind, and has
Good weatherability can repeatedly use, will not be damaged.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of winter road construction maintenance heat preservation felt rug, according to mass fraction, the component for keeping the temperature felt rug includes：Modified cotton fiber
60-80 parts, 10-15 parts of polypropylene fiber, 7-13 parts of polypropylene fibre；
Modified cotton fiber, polypropylene fiber and polypropylene fibre use preceding carry out flame retardant treatment, the fiber after flame retardant treatment, by pre-
Felt rug is kept the temperature needed for being obtained after shredding, essence shredding, combing, lapping, pre- thorn, multiple thorn, whole boiling hot and cutting packing processing.
Preferably, according to mass fraction, the component for keeping the temperature felt rug includes：65-70 parts of modified cotton fiber, polypropylene fiber 13-
15 parts, 8-10 parts of polypropylene fibre.
Preferably, the preparation method of modified cotton fiber is：Cotton fiber is added in the sodium hydroxide solution of 15-20wt%,
Impregnate 30-40min with 35-45 DEG C of temperature, after the completion of dipping centrifugal dehydration rinsed again to neutrality；Rinsing is immersed in absolute ethyl alcohol
With acetone etc. in quality ratio mixed solution, 10-15min is cleaned with 40-60 DEG C of temperature ultrasonic vibration, is centrifuged after the completion of processing
Dehydration；Then by upper step treated cotton fiber impregnation 40-60min in modifying agent, centrifugal dehydration after the completion of dipping；?
To required modified cotton fiber.
Preferably, the preparation method of modifying agent is：According to mass fraction, by 15-20 parts of titanium sulfate, 3-7 parts of urea, metatitanic acid
1-3 parts of butyl ester, 3-5 parts of hydroxymethyl acrylamide sodium, 4-5 parts of chitosan are uniformly mixed, and are dissolved in the deionization of 6-10 times of volume
In water, high-speed stirred obtains modifying agent.
In the present invention, the flame-proof treatment method of modified cotton fiber, polypropylene fiber and polypropylene fibre is as follows：It will modified cotton fibre
Dimension, polypropylene fiber and polypropylene fibre are mixed according to quality parts ratio, are added in flame retardant treatment tank, flame retardant treatment tank is evacuated to
Vacuum state, vacuum degree 30-40kPa keep vacuum state 20-30min, fire-retardant treatment liquid are then added to flame retardant treatment
In tank, fire-retardant treatment liquid addition is subject to floods composite fibre completely, then the air pressure in process tank is added to 0.8-1.5MPa,
After keeping pressure 2-3h, processing pressure tank is released, composite fibre is taken out, after drip water purification point, spontaneously dried under ventilated environment,
Complete flame retardant treatment process；Include following component according to mass fraction in fire-retardant treatment liquid：15-20 parts of melamine, ten bromines two
3-10 parts of phenylate, 15-20 parts of silicon dioxide gel, 30-40 parts of phosphorous flame-retardant object, 180-210 parts of water；Phosphorous flame-retardant object selects phosphorus
One kind in sour ammonium, tricresyl phosphate and ammonium polyphosphate.
Preferably, in flame retardant treatment process, the temperature in flame retardant treatment tank is 60-70 DEG C.
Preferably, the thickness for keeping the temperature felt rug is 20-25mm.
The present invention has following advantageous effect：
The type keeps the temperature felt rug using modified cotton fiber as main fibre materials'use, and coordinates and be added to a small amount of polypropylene fiber
And polypropylene fibre, it both ensure that the heat-insulating property of material, and also improved the intensity and weather resistance of material, to improve heat preservation
The service life of felt rug.The fiber of remodeling heat preservation felt rug is after modified and flame retardant treatment, and intensity improves, and with good
Flame retardant property can reduce the risk that heat preservation felt rug is ignited in dry winter.
Specific implementation mode
The specific implementation mode of the present invention is further described with reference to embodiment, following embodiment is only used for more
Technical scheme of the present invention is clearly demonstrated, and not intended to limit the protection scope of the present invention.
