Abstract
The invention relates to plastic wood taking recycled plastics and walnut shells as base materials, and a processing method of the plastic wood. The processing method comprises the steps of: 1) preparing a raw material, and the like, wherein the raw material of the plastic wood comprises the following components in parts by weight: 60-80 parts of recycled plastics, 120-200 parts of walnut shells, 2-8 parts of coupling agent, 1-2 parts of lubricant, 10-15 parts of calcium carbonate, 1-1.5 parts of antioxygen, and 5-10 parts of polyvinyl alcohol fiber. Compared with the prior art, the plastic wood and the processing method have the beneficial effects that wastes are recycled; the recycled plastics and the walnut shells are converted into serviceable materials; the plastic wood is long in service life and can be used repeatedly; the service time of the plastic wood is above 5 times longer than that of wood; and the manufacturing cost of the plastic wood is one third of that of the pure wood.
Description
Technical field
The present invention relates to a kind of plastic-wood material technical field, especially belong to a kind of and make the plastic-wood material technical field based on kitchen-can bag and the remaining pine sawdust of manufacturing rosin.
Background technology
Moulding wood is a kind of material of construction of very environmental protection, can successfully waste resource be utilized again.Plastic-wood floor has also become building materials industry to develop the waterproof and dampproof high environmental protection of new direction, plastic wood sheet, combine the plurality of advantages of vegetable fibre and plastics macromolecular material, can substitute timber in a large number, can effectively alleviate China's Forest Resources poorness, wood supply contradiction in short supply, be a kind of low-carbon (LC), green, renewable ecological plastic-wood material capable of circulation that has development prospect.
Old plastics, it is white pollution, it is the environmental pollution that global urban all has, can both see a large amount of depleted plastics everywhere in various public places, they come from nature, make by the mankind, but be difficult for when finally ascribing the Nature to being dissolved, thereby influenced the ecotope of the Nature by nature.From the angle that economizes on resources because the plastics main source is to face exhausted petroleum resources, should reclaim as far as possible, but since present stage the production cost that reclaims again far above direct production cost, under existing condition of market economy, be difficult to accomplish.
Nut-shell, because its surperficial many micropores, adsorption effect are better, some factories can carry out filtrate and polish abrasive with it, become a kind of natural tumbling material then.But in vast Rural areas, nut-shell all is to abandon or fill up processing as rubbish.How with old plastics and nut-shell after the proportioning combination of science, in addition routine is moulded wooden processing and manufacturing technology again, can become a kind of novel plastic-wood material.
Summary of the invention
The present invention has solved the problems referred to above just, provides a kind of and moulds wooden material based on kitchen-can bag and the remaining pine sawdust manufacturing of manufacturing rosin.
The present invention is by realizing to foretell technical scheme.
A kind of with old plastics, nut-shell be base-material mould wood and working method thereof, step of the present invention is,
1) raw material is prepared: the weight of this plastic-wood material consists of: old plastics 60-80 part of recovery; Nut-shell: 120-200 part; Coupling agent: 2-8 part; Lubricant: 1-2 part; Lime carbonate: 10-15 part; Oxidation inhibitor: 1-1.5 part; Polyvinyl alcohol fiber: 5 ~ 10 parts; Wherein said nut-shell is at first pulverized, and its fineness is for being no more than 120 orders; Dry then, make its water ratio for being no more than 5%; It is fire-retardant, heat insulation, heat-resisting, intensity, protection against corrosion in order to increase this plastic-wood material that the present invention uses polyvinyl alcohol fiber.
2) carry out auxilliary heating of electricity and high-speed mixing after the old plastics that reclaim in the above-mentioned raw materials and nut-shell proportioning are finished: the temperature of the auxilliary heating of electricity is controlled at 80 ℃ ~ 90 ℃; High-speed mixing is carried out in homogenizer, and rotating speed is 2000 ~ 2200 rev/mins; It is in order to increase the degrees of fusion of this plastic-wood material that the present invention adopts 80 ℃ ~ 90 ℃ Heating temperature and 2000 ~ 2200 rev/mins high-speed mixing technology.
3) dehumidifying: the humidity of mixture is controlled at 5 ~ 10 %; Adopting the humidity control technique of 5 ~ 10 % is in order to increase the conjugation of raw material in this plastic-wood material;
4) cooling: the mixture after will dehumidifying is positioned in the refrigerating chamber and cools off, and is cooled to 1 ℃ ~ 5 ℃, packs standby then; Adopting 1 ℃ ~ 5 ℃ cooling technology, is intensity and the toughness in order to increase this plastic-wood material.
5) compound is transported to conical double-screw granulating equipment and add coupling agent, lubricant, lime carbonate, oxidation inhibitor, under 170 ℃ ~ 180 ℃, carries out mixing extruding then, form the work in-process of moulding woodwork by prescription; Adopt 170 ℃ ~ 180 ℃ extrusion temperature, just be fit to the mixing of old plastics and nut-shell and other components thereof, and it is rotten to be unlikely to produce the material that molecular shape change causes.
6) reprocessing: the work in-process that will mould woodwork promptly become qualified finished product through after sanding-wire drawing-embossing-fixed length cutting operation.
Nut-shell of the present invention is the nut-shell that originates from Yangbi county, Yunnan Province.Adopt the Wood products of moulding of Yangbi county, Yunnan Province making, its hardness is higher, and color is darker, liked by the human consumer.
The present invention compared with prior art, beneficial effect is: utilization of waste material changes into spendable material with old plastics and these two kinds of rubbish of nut-shell; Long service life, repeatedly reusable, average specific timber is long more than five times duration of service; Low cost of manufacture is 1/3 of pure timber manufacturing cost.
The product that the plastic-wood material of this component is made can reach the lumber yard industry standard of moulding.
Below in conjunction with embodiment the present invention is done further explanation.
