Be modified plant powder the powder mix of Plant Powder and PVC powder, softening agent, silicone powder and stablizer is mixed into the Plant Powder be mixed in the step of compound.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Wood fiber composite board of the present invention and manufacture method thereof, wood fiber powder is combined with plastics, there is the texture of natural timber, and physical and mechanical properties is better than timber, in use, can carry out holing, cut, dig milling and finishing, be widely used in material of construction, railroad tie, Hua Lan, outdoor tables and chairs etc.Wood fiber composite board of the present invention has great importance to the substitute of seeking timber, is also one of effective way of recycled plastic regeneration.
Accompanying drawing explanation
Fig. 1 is the schema of the manufacture method of the Wood fiber composite board that the embodiment of the present invention provides.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the present invention is described in more detail.Should be appreciated that, these describe just exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
The embodiment of the present invention provides a kind of Wood fiber composite board, Wood fiber composite board is processed into by rolling process by the component of following weight part: 100 parts, polyvinyl chloride powder, 8 ~ 9 parts, softening agent, silicone powder 5 ~ 6 parts, wood fiber powder 300 ~ 350 parts, stablizer 1 ~ 10 part.
In the present embodiment, the particle diameter of wood fiber powder is such as 700 orders.
Further, the material of Wood fiber composite board also comprises coupling agent, and the parts by weight of coupling agent are 13 ~ 18 parts.
Concrete, when Wood fiber composite board, such as get the PVC powder of 100 parts, the softening agent of 8 ~ 9 parts can be got accordingly, the silicone powder of 5 ~ 6 parts, the wood fiber powder of 300 ~ 350 parts, the coupling agent of 13 ~ 18 parts, the stablizer of 1 ~ 10 part, then above-mentioned materials is mixed in a certain order, concrete, wood fiber powder first mixes with coupling agent, PVC powder elder generation and softening agent, silicone powder and stablizer mixing, and then by the mixture of wood fiber powder and coupling agent and PVC powder, softening agent, silicone powder mixes mutually with the mixture of stablizer, then through mixing, calendering and cooling forming, finally form Wood fiber composite board according to certain specification cutting.
It should be noted that, in the present embodiment, coupling agent is that special coupling agent moulded by wood, be such as a kind of in silane coupling agent, titante coupling agent, aluminate coupling agent or their composite coupler, coupling agent is used for anticipating the surface of wood fiber powder, to improve the interface avidity between PVC powder and wood fiber powder, strengthen consistency between the two.Silicone powder is for improving tensile strength, oil-proofness, the wear resistance of Wood fiber composite board.
Refer to Fig. 1, present invention also offers a kind of manufacture method of Wood fiber composite board, it comprises the following steps:
Step S1: add coupling agent in wood fiber powder, makes modification wood fiber powder, and then improves the consistency of wood fiber powder and PVC powder.Concrete, one or more mixtures in wood powder, bamboo powder, chaff powder and straw powder are dry at certain temperature (such as 105-110 DEG C), until moisture content≤3%, then wood fiber powder be placed in high mixer and add coupling agent, mix and blend certain hour (such as 15 ~ 25min), for subsequent use to obtain modification wood fiber powder.More specifically, in the present embodiment, calculate according to parts by weight, the parts by weight of coupling agent and wood fiber powder are respectively: 13 ~ 18 parts, 300 ~ 350 parts.
