Abstract

The invention discloses a technology for processing special materials such as waste plastic and wood, belonging to utilization of waste. The adopted materials, such as waste plastic, nylon, rubber, chemical fiber, vegetable fiber, asbestos, waste and varied wood, bamboo, crop straw and the like, all belong to utilization of waste. To strengthen the physicochemical properties of the product, heat fusible plastic and the like are subject to heat fusing and processing, wood, bamboo, crop straw and the like are subject to pyrolysis and destructive distillation for removing other fraction or oil or non-fiber matters to change the molecular structure, the apertures among the fiber are enlarged, and comprehensive processing of enhancing the viscosity with heat fused plastic is carried out to obtain the matter; the matter is fully agitated with the heat fused plastic and rubber (under heat preservation for standby use), according to need, keel, namely, metal filaments or non-fusible fiber warp and weft filaments are added, non-fusible fiber filaments (short) are inlaid, and according to actual need, fire retardant, intensifier, foaming agent, pigment and the like can be added. The invention has scientific design and reasonable formula, can be directly poured into a die to be made into a product, and can be manufactured into various section bars of round, square, plate and tube shapes, can be manufactured by planning, sawing, riveting and the like as the same as the traditional modes, and also can be processed into slurry for standby use.

Description

Technology for processing special materials such as waste plastic and wood

Technical field:

The invention belongs to a kind of raw material, also is that further processing becomes section bars such as various circles, pipe, side, plate or directly inject mould to become a certain specific product specifically, intends or can be used as a kind of semifinished material, is processed into the product in adaptation field arbitrarily.

Background technology:

Existing product, or be plastic waste, waste rubber, scrap rubber film; Be that all sufficient basically conducts such as waste wood, useless bamboo, useless stalk have been fallen without any the waste treatment that is worth, even can be to polluting naturally.Can be for 200 years as materials such as plastic wastes at the underground landfill, also have cloth etc. can be on the landfill of underground century-old, and these materials also can decompose in the landfill process and discharge poisonous and hazardous material, make the soil of institute's landfill for good and all lose harm such as use value.The present invention makes full use of waste material, utilizes scientific methods to make refuse become the precious resources that can support utilization again.

Summary of the invention:

The object of the present invention is to provide a kind of method of processing waste of simple science, make this waste can produce useful benefit.

Purpose of the present invention is achieved by following technical proposals: see technical process Fig. 1 and shown in Figure 4 for details: waste and old weedtree, useless assorted bamboo wood, agricultural crop straw, pulverize through roughing, and remove cut oil and non-fibrous material by pyrolysis, destructive distillation.Its effect is to strengthen interfibrous aperture, changes the original physical structure, but adhesive tighten and improve, also can make the easier infiltration of solubility plastic cement therebetween; To give up mould, that soluble substance such as glue fuses into liquid by hot melting way is thick stand-by; The aforementioned material that both have handled well is fully mixed.Add keel according to the actual needs and be tinsel screen cloth or fiber wire screen cloth or be woven into hole pattern or warp and woof places above-mentioned mixing viscous paste; Also can add the usefulness of fire retardant again according to the difference of Application Areas in order to fire prevention.Add whipping agent, can play the effect of thermal insulation sound insulation light weight.Can add stiffeners in order to increase hardness.For snap cure, can add peptizer.In order to reach natural colored, can add relevant colorant etc.This invention technology can become the processing of treatment of wastes produced thing the liquid slurry at any time injection molding use of raw material as no form; Also can processing become section bar such as circle, side, plate, pipe and other heterotypic material; Can also directly inject in the mould and become product (finished product).As be processed into sheet material, square bar etc. and can go out actual needed material product referring to Fig. 2 and the section bar of finishing shown in Figure 3, wait to be reprocessed into other arbitrary products.

Embodiment:

Below in conjunction with description of drawings the specific embodiment of the present invention is further described.

Fig. 4 is that plastic waste is pulverized again behind pyrogenation and carbonization through roughing with useless weedtree bamboo stalk after roughing is pulverized for raw material, both enter hot melt digestor 58 through

funnelled pipe

57 or 54 and fully heat and make hot melt mould liquid to immerse in the Wood-bamboo straw fully joining respectively in

bucket

56 or 55, make the also complete infiltration of Wood-bamboo straw go into hot melt and mould in the liquid, and lump together fully.Enter agitator 52 through funnel 59 again, electric motor 51 high speed rotating make agitator 52 high-speed stirring, mix thing post 60 and make the mixing that enters mould wooden liquid to mix and produce a large amount of bubbles more fully thoroughly.Mix thing thoroughly again through containing mixture bucket 61 through mixture vomit pipe 62.Enter at last and be processed in the hot melt insulation jars 2,5,10,17,41,43,44,45,46 among Fig. 2 or Fig. 3, also can be processed into other section bars such as square bar, roundwood, tubing or other profiled materials etc. as Fig. 2, second splint material, three-ply wood material, four clamping plate materials and five-layer plywood material shown in Figure 3.Also can directly inject and become specific product in the mould.Also can keep and mould wooden mixed slurry and be processed into other products arbitrarily.Can in agitator 52, add according to actual needs actual required additive as: fire retardant, whipping agent, toughener, peptizer or colorant etc. are actual required to satisfy, promptly can add wherein one or more separately, also can add whole additives, change the physicochemical property of moulding wooden former material or product with this, further strengthen its function.

Of the present inventionly mould wooden special material, can greatly solve environmental pollution, turn waste into wealth, simultaneously can save a large amount of forest tree resources, main is will mould wooden special material greatly to develop its generation effect of diving, and it is raw material both, also can be semi-finished product, can also be specific finished product. Such as materials for wall, can directly be poured in the template can or the face of falling down to the ground be processed into the floor, method is directly to pour on the ground to flatten sanding and polishing and carry out stamp, or arbitrary mode such as flocking or pressure is processed, both both artistic and practical, again economical and practical, can repeatedly process the characteristics such as improvement, reprocessing. Its floor of being processed into, wallboard, door-plate do not encircle and do not stick up indeformablely, can dig and can bondingly be reinforced but can follow closely riveting. As be processed into table, chair, stool, drawer, door, window etc. and can directly inject one-shot forming in the mould, become an integral product. Processing and implementation simply firmly fast, at any time can be cut to change to cut out and reprocessed, and are not afraid of uselessly, carry out after the again melting again usefulness, the advantages such as Infinite Cyclic use even if given up.

The present invention is also required according to reality, can add permanent look, luminescent material, what color all can, namely can light as new as long as carry out sanding and polishing. The painted surface effect of also can again painting on article is equally splendid.
