Abstract
The invention discloses a preparing method of a bamboo powder reinforced high density polyethylene material. The preparing method comprises a bamboo powder coupling step and a composite material preparing step. The interaction between bamboo powder obtained after treatment of an aluminate coupling agent and HDPE is enhanced, bamboo powder is evenly dispersed, and impact performance and tensile performance are obviously improved. The section of the composite material is more flat, fine and smooth, and the flowing rate of polymeric material melt is reduced.
Description
Technical field
The present invention relates to plastic applications, be specifically related to a kind of bamboo powder and strengthen high-density polyethylene material
Preparation method.
Background technology
Along with becoming increasingly conspicuous of environmental problem, the composite with Environmental compatibility is increasingly subject to
Favor to market.In recent years, natural plant material because of aboundresources, cheap, density is low,
And its modulus and hot strength close with inorfil, the most also have can reprocessabilty, be difficult to
Water suction is made moist, the feature such as biodegradable, is increasingly subject to people's attention as reinforcing material.
China's bamboo resource enriches, and have bamboo kingdom " title, and bamboo fibre is as Plant fiber's
One class, has antibacterial, deodorant performance and excellent coloring, wearability, and the cost of uniqueness
Relatively low, plasticity is good.Bamboo powder is that of bamboo utilization now is important as plastic reinforcement
Developing direction, high density polyethylene (HDPE) (HDPE)/bamboo powder composite material has plastics and bamboo wood simultaneously
Premium properties, and recoverable, production cost is low, in the premise improving resource utilization
Under, the protection to environment also functions to remarkable effect.Bamboo-plastic composite material is with bamboo powder for strengthening material
Material, resin is matrix material, and reinforcement is main stress composition, and reinforcement is cohered into by resin
Entirety, can make reinforcement entirety stress, can protect the fibers from again mechanical damage or chemistry is rotten
Erosion.But the compatibility is poor between polarity bamboo powder surface and nonpolar substrates, also make whole compound
Material mobility in the course of processing is poor.
Summary of the invention
It is an object of the invention to overcome defect present in prior art, it is provided that a kind of mechanical property
The preparation method of bamboo powder enhancing high-density polyethylene material that can be good.
For realizing above-mentioned technique effect, the technical scheme is that a kind of bamboo powder strengthens highly dense
The preparation method of degree polythene material, it is characterised in that said method comprising the steps of:
S1: bamboo powder coupling, is equipped with bamboo powder in the reactor of ethanol, by reactor
Add aluminate coupling agent, sonic oscillation 30～50 minutes, 80 DEG C of drying baker be dried 24h,
Obtain the bamboo powder of coupling processing；
S2: the bamboo powder of dry high density polyethylene (HDPE) and S1 gained coupling processing is mixed, adds
Enter ultra-high molecular weight polyethylene, mix homogeneously in high-speed mixer, join in mill and open
Refining, broken pelletize, obtain bamboo powder and strengthen high density polyethylene (HDPE)；
The weight ratio of the bamboo powder of described high density polyethylene (HDPE) and coupling processing is 5: (1～2).
Wherein, described mill fabrication process condition is: preliminary roller 160 DEG C, back roller 150 DEG C, note
Penetrate machine injection temperature 160～170 DEG C, injection pressure 50～60MPa.
Wherein, the granularity of described bamboo powder is 150～250 mesh.
Wherein, the addition of described ultra-high molecular weight polyethylene account for described bamboo powder strengthen high density gather
The 6～9% of ethylene total amount.
Advantages of the present invention and having the beneficial effects that:
The Interaction enhanced between bamboo powder and HDPE after aluminate coupling agent processes, bamboo
Powder is uniformly dispersed, and impact property and tensile property significantly improve, and composite section is more smooth,
Moist, polymeric material melt flow rate (MFR) reduces.
