Abstract
Through the steps of cleaning, tumble drying, punching, molding, rolling and coating with film, the waste plastics is produced into densified plate. According to different requirement, the present invention may be further produced into waterproof and moistureproof packaging case or farm tools, such as basket. The present invention makes it possible to reduce the environmental pollution caused by waste plastics while saving other material.
Description
The invention belongs to the recovery and the utilization of waste or used plastics, be specifically related to a kind of sheet material and processing method thereof of utilizing waste or used plastics processing.
As long as we pay close attention to a little, no matter be city or rural area, waste or used plastics is seen everywhere.Disposable plastic bag, disposable tableware, varieties of food items packaging bag, topotype or the like, because these waste plastics need the very long time to decompose voluntarily at nature, some makes new plastic products, a kind of effective way that economizes on resources, reduces pollution of can yet be regarded as through reclaiming back reprocessing at present.But in the face of pile up like a mountain, huge day by day waste plastic must be sought the approach that more utilizes again.In recent years, China's Forest Resources is day by day deficient, paper price one rises and rises again, if a large amount of waste or used plastics process recovery can be processed into agricultural tools such as all kinds of packing cases and basket, dustpan, basket, both can save a large amount of forest reserves, reduce and pollute, open up a new way for reclaiming and utilizing waste plastics again.
Provided by the present invention is exactly a kind of sheet material and method for processing thereof of utilizing waste or used plastics processing.
The sheet material that the present invention processed is primary raw material with the waste or used plastics.
Above-mentioned waste plastics is meant the waste plastics articles for use of the following thickness of 1MM.
Processing method of the present invention comprises the steps that mainly (1) is with waste or used plastics cleaning, broken, drying; (2) punching, mold pressing; (3) roller pressure, overlay film.
Punching, mold pressing in the described step (2), be meant with broken plastics as required the machining sheet specification place certain thickness and enter in the mould, the cope match-plate pattern drift is heated to 250 ℃, lower bolster is heated to 100 ℃ and is made its deliquescing, die pressure is 5-15T, and when the drift of high temperature slowly penetrates plastic layer, the punching periphery plastifies rapidly, solidifies, the bed of material also becomes knot, hardening with die pressure after softened by lower bolster and drift waste heat, becomes strong close hole shape sheet material;
Above-mentioned close hole shape sheet material carries out overlay film after the roller press-stretched is flat, or on the direct overlay film with pattern, color reentrant sheet material.Can make various packing cases (box) according to market demand.
The experiment proved that: the made packing case (box) of the present invention is 10 times of packing case (box) service life, the tension anti-impact force is strong, and alternative Wooden packing container and injection molding material packing case were not only wear-resisting but also have a certain toughness, real and heavy, folding and is constantly pressed and not broken; Waterproof and dampproof function admirable if mix the use of foam, is desirable wrapping tool to metal species and glass, porcelain.During regeneration, only need remove overlay film, overlay film once gets final product again again.Simultaneously, this sheet material also can be made various agricultural tools, and is durable in use as basket, dustpan, basket etc., can save a large amount of forest resourceies.
Embodiments of the invention are described in detail in detail below.
Embodiment 1, with the waste plastics bag that reclaims, disposable tableware, topotype etc., after cleaning, use crusher in crushing, enters the automatic transport band after the drier drying, and the automatic transport band is sent into particle and sprawled into the width of 300MM according to required absolute altitude automatically.After entering forcing press, the cope match-plate pattern drift is heated to 250 ℃, and lower bolster is heated to 100 ℃, middle template does not heat, and drift slowly penetrates the particle layer, and pressure is 5T, step back soon, hauled out by the batch (-type) hauling machine, the plastics of visible drift periphery are cured, plastic layer becomes knot, hardening after softened by lower bolster and drift waste heat under the effect of pressure, become strong close hole shape sheet material, press through roller again, remove the overlap of hole periphery,, utilize the disposable packing case of preparing of template again with propylene film overlay film.
Embodiment 2, prepare the sheet material that width is 500MM as embodiment 1, and operating pressure is 10T, utilize the template cutting to go out basket, basket, dustpan again.
Embodiment 3, prepare the sheet material that width is 800MM as embodiment 1, and operating pressure is 15T, utilize template to prepare packing case again.
Embodiment 4, prepare the sheet material that width is 1.2M as embodiment 1, utilize template to prepare packing case again.
