Description
Technical field
The invention belongs to natural-fiber composite material and wood plastic composite technical field, refer to that specifically a kind of plastics strengthen with flaxen fiber and preparation method thereof
Background technology
In recent years, the research of natural plant fibre matrix material and wood plastic composite aspect was in the ascendant.On the one hand because the wide material sources of natural plant fibre are cheap; Aspect of performance natural plant fibre reinforced plastics has greatly the trend that replaces mineral fibre reinforced plastics on the other hand.
Most natural plant fibres are with the macrofiber shape or hot-forming with thermosetting resin again after being compiled into fibrefelt, can not directly join to be used for injection moulding in the thermoplastics as glass; Natural plant fibre is on the one hand because the rich surface hydroxyl shows strong polarity and wetting ability, with the Compatibility in Plastics extreme difference of nonpolar or low-pole, the poor performance of the matrix material of preparation simultaneously; Because the vegetable fibre volume is large, loading level is large, the friction between fiber and plastics, fiber and equipment and the fiber is large so that vegetable fibre reinforced plastics is difficult to processing, especially for injection molding on the other hand.In order to solve the compatible problem of vegetable fibre and plastic interface, main solution is added interfacial compatibilizer exactly at present, one class is the coupling agent class, such as silane coupling agent, titanate coupling agent, aluminate coupling agent, rare-earth coupling agent, isocyanate coupler etc., another kind of is maleic anhydride and polyolefinic grafting or multipolymer.The coupling agent class is most few and be not easy to evenly spread in the vegetable fibre for volume, affects its coupling effect, and industrial application needs special equipment to process; Maleic anhydride and polyolefinic grafting or multipolymer majority are that particulate state is distributed in plastics and the vegetable fibre easily, are difficult to improve interfacial adhesion but its percentage of grafting is low.However, fill a large amount of vegetable fibres and the mixture of plastics and also bring difficulty to processing, be difficult to extrude or injection molding.In order to solve the processing problems of vegetable fibre and plastics composite, various processing aids appear, and such as alkene wax, amide waxe, stearic acid, Zinic stearas, calcium stearate etc., but the adding of too much processing aid also can be so that the degradation of matrix material.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, primary and foremost purpose of the present invention is to provide a kind of plastics to strengthen and uses flaxen fiber.
Another object of the present invention is to provide above-mentioned plastics to strengthen the preparation method who uses flaxen fiber.
For achieving the above object, the invention provides following technical scheme: a kind of plastics strengthen uses flaxen fiber, and this plastics enhancing is comprised of following component by weight with flaxen fiber:
Described chopped ramie fiber is more than one in ramee, flax fiber, sisal fibers, jute fibre and the burnt flaxen fiber.
Described flaxen fiber treatment agent is urea-formaldehyde resin performed polymer, trimethylol melamine resin or hexamethylol melamine resin.
Described Functional Polyolefine is more than one in metallocene polyethylene wax, metallocene polypropylene, metallocene-polyolefin, oxidation metallocene-polyolefin waxes and the metallocene-polyolefin waxes-maleic anhydride grafts.
Described coupling agent is more than one in silane coupling agent, titanate coupling agent, aluminate coupling agent, isocyanate coupler and the rare-earth coupling agent.
Described oxidation inhibitor is antioxidant 1010 and irgasfos 168, and both mass ratioes are 2: 1.
Above-mentioned a kind of plastics strengthen the preparation method with flaxen fiber, comprise following operation steps:
(1) flaxen fiber is cut to 1～20mm, obtains chopped ramie fiber; After placing aqueous sodium hydroxide solution to soak the chopped ramie fiber and stirring 1～20min, clean with flushing with clean water, dry after drying moisture content, be immersed in again temperature and be 5min～30min in 80～90 ℃ the flaxen fiber treatment agent aqueous solution, after flaxen fiber exhausts the flaxen fiber treatment agent aqueous solution, oven dry obtains surface treated chopped ramie fiber;
(2) surface treated chopped ramie fiber, coupling agent, Functional Polyolefine and oxidation inhibitor are joined in the kneader that is preheated to 70～80 ℃ successively, stir, obtain plastics enhancing flaxen fiber.
The mass percent concentration of the described aqueous sodium hydroxide solution of step (1) is 1%～10%; The mass percent concentration of the described flaxen fiber treatment agent aqueous solution is 10%～50%; Described drying moisture content is to adopt centrifugation to dry moisture; Described dry be dry in the air to the quality water ratio be 8～15% (normal moisture contents of flaxen fiber).
The described oven dry of step (1) is to adopt vacuum-drying to dry, and bake out temperature is 90～150 ℃, dries quality water ratio to flaxen fiber less than 1%; Described with flushing with clean water for washing to pH 7.0～9.0.
The time of the described stirring of step (2) is 5～10min; The speed of described stirring is that per minute 50～300 turns.
Principle of the present invention is: the present invention is by the impurity of sig water flush away fiber surface, process with the aqueous solution of the treatment agents such as urea-formaldehyde resin performed polymer, trimethylol melamine resin or hexamethylol melamine resin again, the hydroxyl of fiber surface and the methylol for the treatment of agent react, coat last layer urea-formaldehyde resin or melamine resin at fiber surface, reduced the surface polarity of flaxen fiber, lower the water-intake rate of flaxen fiber, improved simultaneously rigidity and the thermotolerance of flaxen fiber; Improve again the consistency of flaxen fiber and plastics by coupling agent, and improve oilness and the dispersiveness of fibrous inside by Functional Polyolefine.
Compared with prior art, the present invention has following beneficial effect: the chopped ramie fiber color and luster of the present invention's preparation is good, rigidity and good heat resistance, can equally join in the plastic substrate by the direct image short glass fiber, good with the consistency of plastics, can be used for preparing high performance cast tow fiber plastics composite, and in plastic substrate, play the effect of enhancing.
