Description
Technical field
The invention belongs to technical field of composite materials, and in particular to a kind of bamboo fibre environment-friendly materials and its manufacture method.
Background technology
Working of plastics, which is widely used in, makes inner and outer decorative parts of automobile and commodity, and automobile decoration piece has the work of decoration and beauty automobile
With the quality of its decorative effect directly influences image inside and out automobile.Existing inner and outer decorative parts of automobile is mostly using modeling
Expect that particle (such as PP, PE, PET, PA, ABS) is completed in the form of Shooting Technique.Plastic pellet smell itself is dense, is pungent, and uses
During the peculiar smell that distributes at high temperature it is stronger.While making automobile consumer unable to endure any longer, but also what nothing is resistant to.In Chinese city
There are automobile factory and parts producer in place, improves always without more preferable material or technique.
Plastic pellet cost is average 10,000 yuan/ton, and working of plastics, because high temperature can be deformed, causes product size essence after depanning
Deviation is spent, frock need to be increased or post-processing just can guarantee that so that working of plastics cost is higher.For cost, all kinds of manufacturer poles
Power controls.To be cost-effective, after typically using a certain proportion of feed back, feed back to use repeatedly, product strength is had greatly
Influence, such as embrittlement, easy folding line.So that rapid wear, cause terminal client bear bigger consumptive power after stress in working of plastics
Meanwhile quality cannot ensure.
The content of the invention
The first object of the present invention is to solve the above problems, there is provided a kind of bamboo fibre for reducing manufacturing cost, improving peculiar smell
Environment-friendly materials.
Technical scheme is used by realize the first purpose：A kind of bamboo fibre environment-friendly materials, including bamboo fibre powder and modeling
Expect particle, bamboo fibre powder and plastic pellet press 1:4~8 weight is than proportioning.Bamboo fibre powder is made up of pure plant material, face
Color is its true qualities, i.e., faint yellow.
Preferably, the bamboo fibre environment-friendly materials also include Masterbatch, and bamboo fibre powder, plastic pellet and Masterbatch press 1:4
~8：0.01~0.02 weight is than proportioning.
Preferably, ash is less than 2% in the bamboo fibre powder, and water content is 8~12%.
Preferably, the grain diameter of the bamboo fibre powder is 20~60 mesh.
Preferably, the plastic pellet is by polyolefine material (PE PP PS), polyamide material (PA), polyphenylene oxide fat material
(PET PBT PC PPO), acrylate material (PMMA) or styrene-butadiene-acrylonitrile materials (ABS) are made.
The second object of the present invention is to provide a kind of manufacture method of bamboo fibre environment-friendly materials, and product strength is made more in it
Greatly, better quality.
Technical scheme is used by realize the second purpose：A kind of manufacture method of bamboo fibre environment-friendly materials, including with
Lower step：
S1, according to the weight ratio weigh bamboo fibre powder and plastic pellet；
S2, the material weighed is mixed to be formed to mix and just expected；
S3, by mixing, just material pours into barrel, and the uniformity of bamboo fibre powder and plastic pellet is observed by barrel observation window,
It is not stratified with two kinds of materials；
S4, it is molded by Shooting Technique.
Preferably, also include weighing Masterbatch in the step S1, bamboo fibre powder, plastic pellet and Masterbatch press 1:4~
8：0.01~0.02 weight weighs than proportioning.
Preferably, barrel design temperature is higher than 5~30 DEG C of the fusing point of plastic pellet in the injection moulding process.Slightly higher temperature
Increase the mobility after plastic pellet fusing, bamboo fibre powder is preferably uniformly distributed in plastics water.Temperature setting should basis
Product area changes with grammes per square metre size variation, and product area is bigger, and temperature is higher, and product grammes per square metre is bigger, and temperature is higher.
Preferably, the weight ratio proportioning of the bamboo fibre powder and plastic pellet is 1:6.Under matching herein, the rigidity of product
And toughness is optimal, weight also hardly increases.
The beneficial effects of the invention are as follows：
1st, a kind of bamboo fibre environment-friendly materials provided by the present invention, it is 1 by weight ratio:4~8 bamboo fibre powder and plastic pellet
Son is molded after being mixed evenly, and due to adding bamboo fibre powder, obtained product peculiar smell is obviously improved, and has ecosystem
Bamboo fragrance.The unit cost of bamboo fibre powder is less than plastic pellet, therefore the holistic cost of product can reduce about 10%.
2nd, the manufacture method of a kind of bamboo fibre environment-friendly materials provided by the present invention, it is not necessary to additionally increase equipment, raw material
Weigh and be molded after stirring by Shooting Technique.Its obtained product parts intensity is bigger, repeated disassembled and assembled intensity
It is unattenuated, it is hardly damaged, product quality is more preferable, has the market competitiveness.
