Description
Technical field
The invention belongs to wood plastic composite field, it is related to a kind of wood powder-tea stalk powder blending type thermoplastic wood and plastic composite
Material and preparation technology.
Background technology
Wood plastic composite is to enter the material such as the materials such as polyethylene, polypropylene, polyvinyl chloride and wood powder, rice husk, stalk
Row is mixed into new wood materials, then through plastic processings such as extruding, molding, injection mouldings, produces sheet material or section bar, wood
Plastic composite materials have the double grading of timber and plastics, and not only dimensional stability is good, and can make full use of discarded fibre
Dimension, plant and waste plastic, save the energy and reduce environmental pollution, are widely used in interior decoration and outdoor field.
With the improvement of living standards, a kind of approach as people's leisure health of drinking tea, but drink tea when drinking tea
Leaf, does not drink the custom of tea stalk, although nutritional ingredient is limited in tea stalk, but still contains a considerable amount of fragrance in tea stalk
Composition, the recycling for discarding tea stalk is that green energy resource one of is utilized.
Wood plastic composite is different as needed, and the color of material is also different, for the shallower material of color, passes through
The easy aging of long-term use, oxidation jaundice, influence attractive in appearance, and due to containing wood materials in composite so in humidity
In the environment of easily go mouldy breed bacteria, and then influence the weight of indoor environment and air.
The content of the invention
It is an object of the invention to provide a kind of wood powder-tea stalk powder blending type thermoplastic wood plastic composite and preparation work
Skill, the present invention by will wood powder and tea stalk powder mix after with plastics prepare wood plastic composite, it is fragrant that the material of preparation contains tea stalk
Taste and performance, can remove the formaldehyde and peculiar smell in air, can improve air quality, while realizing the reasonable of discarded tea stalk
Utilize, environmental protection.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of wood powder-tea stalk powder blending type thermoplastic wood plastic composite, is prepared by the raw material of following mass fraction：Wood powder

One or more in alkane, maleic anhydride grafting pitch, maleic anhydride grafted polyethylene, maleic anhydride inoculated polypropylene；
The compounded lubricant be stearic acid, fatty glyceride, atoleine, Tissuemat E, glyceryl monostearate,
A variety of mixing in the double oleamides of fatty acid bis-amides, ethylene；
A kind of preparation technology of wood powder-tea stalk powder blending type thermoplastic wood plastic composite, preparation process is as follows：
(1) mix：By in wood powder, tea stalk powder input high-speed mixer, stirring adds composite lubricated when being warming up to 80-90 DEG C
Agent carries out mixed at high speed, it is well mixed after be warming up to 105-115 DEG C, add high density polyethylene (HDPE), talcum powder, antioxidant, ultraviolet
Light absorbers, antimildew and antibacterial agent and grafting compatilizer, continue mixed at high speed to 120-130 DEG C at present to cold mixer cooling；
(2) granulate：By the material after combination cooling by special comminutor in 160-190 DEG C of preplasticizing, by parallel
Twin-screw plasticizing is squeezed into lumps, then is broken into a certain size particle by broken blower fan；
(3) extrusion molding：By the particle made by special extrusion equipment under 150-180 DEG C of moulding process, warp
The mould molding for crossing specific end face is the section bar of certain section.
Wood powder and tea stalk the powder preparation process is：Tea stalk, thick leaf etc. are first passed through into drying, moisture is less than 10%, so
It is milled afterwards, fineness is 60-200 mesh.
Beneficial effects of the present invention：
The present invention prepares wood plastic composite by the use of discarded tea stalk and thick leaf as fibrous raw material, not only realizes the energy
Recycling, and environmental protection, simultaneously because contain a considerable amount of aroma substances in tea stalk, and tea stalk can absorb
Finishing formaldehyde and peculiar smell in air, can improve the quality of room air.
The present invention adds ultra-violet absorber during wood plastic composite is prepared, and can improve the anti-ageing of Wood-plastic material
Change ability, and be used in mixed way with antioxidant can be with long-acting anti-oxidant, anti-yellowing, for the longer light wood moulding of use time
Material does not influence its outward appearance.
The present invention adds antimildew and antibacterial agent during wood plastic composite is prepared, and can prevent because ambient humidity is larger
The growth gone mouldy with bacterium of caused composite, the pollution of air can be prevented for moist environment.
In the Wood-plastic material preparation process of the present invention by the particle made after extrusion equipment is extruded, directly in particular end
The mould in face is molded next time, for Wood-plastic profiles not in specie, it is only necessary to adjust the end face of mould can prepare it is different
Section bar.
