Description
Technical field
The present invention relates to textile material technology, a kind of low formaldehyde flaxen fiber and the preparation method of low VOC composite thereof.
Background technology
Ecological deterioration, resource shortage and energy crisis make human knowledge arrive protection environment and efficent use of resources to realizing society and the importance of sustained economic development and urgency; it is the abundantest that people the most increasingly pay attention to using renewable biological source to manufacture the hemp resource of new material China, is one of fiber crops distribution is the widest, yield is most in the world country.Flaxen fiber, due to natural bacteria resistance, high-strength, light weight, excellent humidity absorption and release function, has been widely used in the every field such as clothing, article of everyday use, home decoration, automotive trim.
Shenzhen Academy of Metrology & Quality Inspection has inspected the new car using not enough half a year the most at random by random samples, and the concentration of the vapour harmful gas in vehicle of 70% is above standard the limit value of regulation as a result, and the highest exceeding standard reaches more than 10 times.In automotive trim field, main source of effumability small organic molecule (VOC) is textile and interior material in car, when it exposes in atmosphere for a long time, will volatilize these organic volatile matters.Owing to flaxen fiber and composite product thereof are during processing or using, harmful VOC class material can be volatilized, constrain the application in automotive trim field of flaxen fiber and composite product thereof to a certain extent.Chinese patent (CN102030945A) uses the compound system of zinc ricinate, metal-oxide (magnesium oxide, zinc oxide, aluminium oxide etc.) and clay mineral system (kieselguhr, Silicon stone) as odor suppressing agents at present, although this technique has reached the effect de-tasted to a certain extent, but substance is many, add production cost, and technics comparing is loaded down with trivial details.Therefore processing technique being presently required simple, with low cost, the low formaldehyde flaxen fiber and the composite material and preparation method thereof thereof that are suitable for production in enormous quantities solve this problem.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of low formaldehyde flaxen fiber and the preparation method of low VOC composite thereof；What the present invention intended to solve technical problem is that, a kind of low formaldehyde flaxen fiber and the preparation method of low VOC composite thereof are provided, aiming to solve the problem that flaxen fiber and composite harmful substance volatile quantity thereof exceed standard serious problem, this preparation method has that technique is simple, with low cost, the feature of clean environment firendly.
Technical scheme is as follows:
A kind of low formaldehyde flaxen fiber and the preparation method of low VOC composite thereof, it is characterised in that described processing method for carrying out heat treated to flaxen fiber, and after using heat treated, composite made by flaxen fiber and polypropylene.
Described a kind of low formaldehyde flaxen fiber flaxen fiber and the preparation method of low VOC composite thereof, concretely comprising the following steps can be that flaxen fiber at high temperature carries out heat treatment, or flaxen fiber carries out heat treatment at low temperatures, also or both are used in combination.Wherein, high-temperature heat treatment temperature is 90 DEG C～150 DEG C, and the high-temperature process time is 10min～50min, and K cryogenic treatment temperature is 50 DEG C～70 DEG C, and the K cryogenic treatment time is 10min～30min.
Described a kind of low formaldehyde flaxen fiber flaxen fiber and the preparation method of low VOC composite thereof, it is characterised in that described flaxen fiber with polyacrylic mass ratio is: flaxen fiber 40～60%, polypropylene 40～60%.
Described a kind of low formaldehyde flaxen fiber flaxen fiber and the preparation method of low VOC composite thereof, it is characterised in that flaxen fiber and polypropylene fibre make composite through shredding, combing, acupuncture, hot pressing.
Compared with prior art, the preparation method of a kind of low formaldehyde flaxen fiber of the present invention and low VOC composite thereof provides the benefit that: with mode of heating to reduce the burst size of methanal of flaxen fiber, the pyrolysis that VOC release main source is pectin, waxiness, lignin in Plant fiber, by heating, a part of harmful substance can be made to volatilize, thus reach to reduce the purpose of burst size of methanal before preparatory phase；Additionally, the VOC in natural-fiber composite material discharges essentially from the pyrolysis of Plant fiber in preparation process；By heating, the harmful substance in Plant fiber volatilizes a part, thus reduces its release of harmful substance in preparation process；Heating simultaneously makes the hydroxyl quantity in Plant fiber reduce, polarity reduces, the compatibility between itself and non-polar resin can be increased, so that both interfaces form higher cohering, promote composite heat stability and hinder harmful species inside to volatilize thus reduce the purpose of composite VOC.Low formaldehyde flaxen fiber and the preparation method of low VOC composite thereof that the present invention provides are simple to operate with existing production technology phase ratio method, and technological process is short, and Expenses Cost is low, and without any substance, clean environment firendly.
Detailed description of the invention:
The present invention is further illustrated below in conjunction with embodiment.
Embodiment 1
Take and carry out formaldehyde examination without the china-hemp fibers of any process.The detection of formaldehyde result shows that untreated china-hemp fibers content of formaldehyde is 16.45mg/kg.
Embodiment 2
By china-hemp fibers heat treatment 10min at 150 DEG C, dry in the air to room temperature after taking-up；Placing into heat treatment 20min in the baking oven of 70 DEG C, dry in the air to room temperature and carry out formaldehyde test, after detection processes, content of formaldehyde is 13.85mg/kg.
Embodiment 3
By china-hemp fibers heat treatment 50min at 90 DEG C, drying in the air to room temperature and carry out formaldehyde test after taking-up, after detection processes, content of formaldehyde is 11.82mg/kg.
Embodiment 4
By china-hemp fibers heat treatment 50min at 150 DEG C, drying in the air to room temperature and carry out formaldehyde test after taking-up, after detection processes, content of formaldehyde is 14.31mg/kg.
Embodiment 5
Take that 50g china-hemp fibers mixes with 50g polypropylene fibre, composite is made in shredding, combing, acupuncture hot pressing.
Embodiment 6
