Abstract
The invention relates to a wood plastic injection molding material and a preparation method thereof. The plastic injection material comprises 40 to 80 weight percent of wood particle material and 20 to 60 weight percent of polypropene (PP) plastic. The preparation method comprises: crushing and drying one or more than two wood waste materials to form a wood particle material; and fully mixing the wood particle material and the PP plastic according to the composition of the wood plastic injection molding material to obtain a target product. The wood plastic injection molding material, which can be recycled, is environmentally-friendly and safe to human bodies; the raw materials of the wood plastic injection molding material (such as trees, tree leaves, saw dust, and leftovers of industrial plates) are readily available, the consumption of plastic can be reduced greatly, the singleness of plastic injection molding material is changed, and the prepared product is very stable, free from contraction deformation and can be recycled; and the operation process is simple, easy to operate and low in cost. The wood plastic injection molding material can be widely used for making plastic products with wood appearance and has very breathable plant cultivating vessels, food and health-care package boxes and the like.
Description
Technical field
The present invention relates to a kind of injectable plastic material and preparation technology thereof, relate in particular to a kind of injectable plastic material that mainly forms and preparation method thereof, this wood materials environmental protection, safety, and recyclable regenerative with wood materials.
Background technology
A lot of injecting products in the market mainly are to form with injectable plastic materials such as vinylbenzene, polycarbonate and polystyrene, these materials contain many harmful chemical components on the one hand, can damage HUMAN HEALTH, cost is higher on the other hand, can not recycle, and be difficult to degraded after discarded, can cause serious environmental to pollute.
Summary of the invention
One of purpose of the present invention is to propose a kind of wooden injectable plastic material, this wooden injectable plastic material is main raw material with the wooden waste, have environmental protection, human body had characteristics such as any injury and recyclable regenerative, and with low cost, thus overcome deficiency of the prior art.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of wooden injectable plastic material is characterized in that, described injectable plastic material comprises following component: wood substance grain material 40wt%-80wt% and PP plastics 20wt%-60wt%.
Say that further described wood substance grain material is that raw material makes after pulverization process with one or more wooden wastes, described wooden waste comprises leaf, wood chip, timber scrap stock and trees.
Another object of the present invention is to propose the preparation method of wooden injectable plastic material as mentioned above, this method flow is succinct, and easy handling is with low cost; This method is:
The wooden waste of getting one or more forms the wood substance grain material after pulverizing, drying treatment, get wood substance grain material and PP plastics thorough mixing according to the composition of described wooden injectable plastic material again, forms target product.
Further say, this method is specially: after the wooden waste of getting one or more is processed into particles, carry out drying treatment again, then pulverize and form the wood substance grain material, get wood substance grain material and PP plastics thorough mixing, granulation according to the composition of described wooden injectable plastic material again, form target product.
Described drying treatment is meant wooden waste air-dry or oven dry in the environment more than 40 ℃.
Preferably, also can comprise the steps: the needs according to practical application in this method, screening meets the particle with predetermined dimension from pulverize the wood substance grain material that forms, then with the particle and the PP plastics thorough mixing that filter out.
Described wooden waste comprises leaf, wood chip, timber scrap stock and trees.
Compared with prior art, the invention has the advantages that:
The present invention adopts recyclable regenerative, environmental protection, and the novel wooden injectable plastic material that human body does not have any injury has been substituted the injectable plastic material of tradition based on plastics, its raw material cheap and easy to get (as, can be trees, leaf, wood chip, the scrap stock of industry sheet material etc.), can significantly reduce the unicity of using and change the injection moulding material of plastics, the product stability of making simultaneously is strong, no shrinkage strain, also can reclaim use repeatedly, in addition, its preparation technology is simple to operation, and is with low cost.Wooden injectable plastic material of the present invention can be widely used in making the injecting products with wood appearance, the plant growing vessel with good ventilation property and food, healthcare products packing box etc.
Description of drawings
Fig. 1 is preparation technology's schema of wooden injectable plastic material of the present invention and injecting products thereof.
Embodiment
Below in conjunction with accompanying drawing and some preferred embodiments technical scheme of the present invention is further described.
Embodiment 1 this wooden injectable plastic material comprises following component: wood substance grain material 40wt% and PP plastics 60wt%.
Embodiment 2 these wooden injectable plastic materials comprise following component: wood substance grain material 80wt% and PP plastics 20wt%.
Embodiment 3 these wooden injectable plastic materials are granular product, and it comprises following component: wood substance grain material 50wt% and PP plastics 50wt%.
The wooden injectable plastic material of the foregoing description 1, embodiment 2 and embodiment 3 can adopt following prepared: the wooden waste of getting one or more forms the wood substance grain material after pulverizing, drying treatment, get wood substance grain material and PP plastics thorough mixing according to the composition of described wooden injectable plastic material again, form target product.
In preceding method, before wooden waste is pulverized, can earlier it be processed into particles (obviously by modes such as cutting, roll, for Powdered or clastic wooden waste, can not comprise this and handle step), then carry out drying treatment, carry out pulverization process thereafter again.This drying treatment process can adopt the particles natural air drying, mode such as dry, but preferred mode is, with particles air-dry or oven dry in the environment more than 40 ℃, to quicken its drying process.
After pulverization process, also can comprise the steps in this method, promptly, according to the needs of practical application (such as, character such as the outward appearance of pre-formation product, intensity), meet the have predetermined dimension particle of (granularity) with screening from pulverize the wood substance grain material that forms such as filter screen, then with the particle and the PP plastics thorough mixing that filter out.
Certainly, the preparation technology of this wooden injectable plastic material also can be included in wood substance grain material and PP plastics thorough mixing, and carry out granulation again and handle, thus the process of formation the finished product.
Aforesaid wooden waste comprises leaf, wood chip, timber scrap stock and trees etc.
The technical process of preparation wooden injectable plastic material of the present invention and injecting products thereof can be consulted shown in Figure 1.
Above preferred embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique under the situation that does not break away from the spirit and scope of the present invention, has been done various conversion or modification, all belongs to category of the present invention.
