Abstract
The invention discloses a preparation method of a modified bamboo fiber/polypropylene composite material. The preparation method comprises the following steps of pretreating bamboo fibers with an alkaline solution or a silane coupling agent; drying the treated bamboo fibers and polypropylene at 40-50 DEG C for 20-30h; starting an internal mixer, feeding the materials at 170180 DEG C and mixing for 10-20min under the condition that the rotor speed is 40-60r/min; and after mixing is finished, crushing the sample and molding in an injection molding machine under the condition that the injection temperature is 200-220 DEG C. According to the preparation method of the modified bamboo fiber/polypropylene composite material, since the bamboo fibers are pretreated with the alkaline solution or the silane coupling agent, the interfacial compatibility is improved when the bamboo fibers and polypropylene are compounded; and the interfacial compatibility of the polar group bamboo fibers and the nonpolar polypropylene in the prepared modified bamboo fiber/polypropylene composite material is excellent so that the prepared modified bamboo fiber/polypropylene composite material can be widely used.
Description
Technical field
The invention belongs to pin textile technology field, relate to a kind of preparation method of bamboo fiber composite material, be specifically related to a kind of preparation method of modified bamboo fiber polypropylene matrix material.
Background technology
Bamboo fiber is a kind of brand-new natural fiber, and be the natural bamboo fibres that the method adopting physics, chemofacies to combine is produced, natural bamboo fiber and bamboo pulp fiber are essentially different, and bamboo fiber belongs to natural fiber, and bamboo pulp fiber belongs to man-made fiber.Bamboo fiber succeed in developing the birth indicating another natural fiber, it meets national industry development policies.
The longitudinal smooth surface of bamboo fibers, homogeneous, there is the groove that many are more shallow; Cross section is close to oval, and edge is irregular.This surface tissue makes bamboo fibers have certain cohesive force, is conducive to the resultant yarn of fiber.
Its cross section is the special construction of height hollow, can attract large quantity of moisture instantaneously and through a large amount of gas, and longitudinally straight, the hole that surface grooves is formed can produce stronger capillary effect, makes bamboo fibers have good humidity absorption and release performance.
Natural antibacterial ingredient in bamboo, can be combined on cellulose macromolecule all the time.So bamboo fiber also can not lose the anti-microbial property of its uniqueness through repetitive scrubbing, Exposure to Sunlight.
Bamboo fibers contains chlorophyll copper sodium, makes its textiles have good deodorization, and chlorophyll copper sodium or safety, excellent UV light absorber, can to a certain degree reduce the injury of ultraviolet to human body.Having experiment to show: the ultraviolet penetration coefficient of bamboo fibers is 0.6%, is cotton 41.6 times.Bamboo fibers can 100% degraded, be Green Product.
Bamboo fibers and cotton fibre blending, can improve the performances such as the spinning property of bamboo fibers, pilling resistance, dimensional stability and sense of fullness, and give the silk quality sense of product uniqueness, ventilation property, drape, flexibility, comfortableness.
Bamboo fibers and wool blendedly can produce frivolous dry-touch type fabric, product has that feel is smooth, elegant, the comfortable feature such as nice and cool of dangling, and be suitable for taking summer, what breach wool fabric takes limitation, enrich wool spinning fabric kind, improve fabric class and added value.
Therefore bamboo fiber products can be widely used in underwear underclothes, shirt, sportswear and infant-wear, especially summer various fashionable dress and the desirable fabric of the home textile product such as sheet, bed clothes, towel, bath towel.
Widely using of plastics, carrying capacity of environment is increased sharply, and natural composite material is subject to extensive concern.Bamboo-plastic composite material has the advantage of bamboo wood and plastics concurrently.The development & application of polypropylene (PP)/bamboo fiber composite material, can reach conservation resource, the object of protection of the environment, but there is the bamboo fibers of polar group and nonpolar PP interface compatibility poor, its matrix material is applied and is limited to.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of preparation method of modified bamboo fiber polypropylene matrix material, prepare the bamboo fibers of polar group and the matrix material of nonpolar polypropylene good interface compatibility.
For achieving the above object, the invention provides following technical scheme:
A preparation method for modified bamboo fiber polypropylene matrix material, comprises the steps:
First with basic solution or silane coupling agent, pre-treatment is carried out to bamboo fibers, dry 20 ~ 30h at 40 ~ 50 DEG C by the bamboo fibers after process and polypropylene, start Banbury mixer 170 ~ 180 DEG C to feed in raw material, rotor speed 40 ~ 60r/min, banburying 10 ~ 20min, by sample comminution after banburying terminates, shaping in injector, injection temperature is 200 ~ 220 DEG C.
Preferably, described bamboo fibers fineness is 100 ~ 300 orders.
Preferably, described bamboo fibers and polyacrylic blending ratio are (3 ~ 4): (7 ~ 6).
Preferably, by the bamboo fibers after process and polypropylene dry 24h at 45 DEG C.
Preferably, start Banbury mixer 175 DEG C to feed in raw material.
Preferably, rotor speed 50r/min, banburying 15min.
Preferably, injection temperature is 205 DEG C.
The preparation method of modified bamboo fiber polypropylene matrix material of the present invention, with basic solution or silane coupler solution pre-treatment bamboo fibers, improve interface compatibility when itself and polypropylene composite materials, the bamboo fibers of the matrix material polar group prepared and nonpolar polypropylene good interface compatibility, make bamboo fibers polypropylene composite material be more widely used.
