Abstract
The present invention relates to a method for manufacturing building sections from two kinds of waste, namely terylene waste and shopping vest bags as basic materials and glass fibres as reinforcing materials. Door and window frames made from the sections are as regular as doors and windows made from aluminium alloys. The sections which can be combined by bonding without welding have the advantages of excellent corrosion resistance, low manufacture cost and good price competitive edge.
Description
The present invention relates to a kind of polymer garbage reclamation and utilize method.Its product is used to build worker's material.
Alumium alloy door and window are extensively favored because of its outward appearance is regular and durable.Be difficult to popularize but cost an arm and a leg.Moreover, if use this door and window at large, in large quantities, certainly will bring again and can't bear burden ground energy consumption.
With the compound plastic door-window of PVC/ steel, because welding inconvenience, the processing that need be prefabricated in the factory of a lot of parts does not have any advantage again on price.Thereby occupation rate of market is more low always.
The present invention adopts and reclaims terylene (PET) rubbish is primary raw material, and the door window frame of manufacturing is, remunerative price low except that cost competed, also because PET has a lot of good performances.At first, its hardness is the hat of thermoplastic, and its fiber reinforced material performance is bordering on thermosetting plastics.And good creep resistant, fatigue durability and be better than the resistance to ag(e)ing of glass fiber reinforced plastic, all be a kind of very good worker's material of building.But, we can not directly make door window frame with the commodity REINFORCED PET, because it is too expensive.
Adopt the PET waste recovery to utilize method, can the workout cost problem.But because the PET after the fusion, as stretching without directed rubbish, cooling back embrittlement does not have value.So, abroad the PET refuse except that those than can be used as the fiberfill fibers of the wire drawing again (this silk can not remake fabric) that is easier to separate to purify, major part is still burnt by Buddhist.Therefore, recycle this material, the problem that at first faces is exactly a toughening modifying, overcomes its fragility.Did a little researchs abroad in this respect.Its typical case's report is found in Eng, Plastic 1991 (1).
The current means toughness reinforcing to PET, more feasible is to add second kind of polymer, and this base polymer can be an elastic body, can be polyolefin also, makes its alloying, and Drink bottle holder is exactly with the toughness reinforcing example of HDPE.But, because HDPE and PET compatibility are poor, so before blend, need chemical modification in advance.On the other hand, according to reports, a lot of blending and modifyings need carry out under protective gas or vacuum condition.
The objective of the invention is to find a kind of method, is practicable under most of medium-sized and small enterprises existing equipments and technical condition, and simultaneously with low cost, product is competitive.
The object of the present invention is achieved like this: at first selecting for use with HDPE is the shopping plastic bag discarded object of main material (remainder is a spot of LLDPE and PP), and this material source is wide and cheap.On the other hand, the calendering process that adopts the present invention to propose.Adopt this technology, HDPE does not need chemical modification, and all calendering process can carry out in traditional common mixing facilities.
The technology that the present invention proposes is characterized in that: add PET and other component again after only needing earlier HDPE and glass fiber fully mixed, just can solve the problem that HDPE separates with PET.
Produce test piece with two kinds of methods, first method is HDPE to be mixed the back add glass with PET, and second kind is the method that proposes with the present invention.Preceding a kind of bad mechanical property, this can see from the tomography with two kinds of test pieces: the former HDPE is distributed in the PET continuous phase with island, and latter HDPE is netted.
Embodiment 1, is the material with the method blend of the present invention's proposition, the test piece of suppressing with 5Mpa pressure on hydraulic press.The test piece smooth in appearance, springiness.
From test the effect that this method is toughness reinforcing can be described, but can not represent the performance of actual product, because a lot of conditions more help crystallization in the extrusion.Figure (1) is the typical section structure of this section bar, and factory can make the different cross section section bar according to demand certainly.
This section bar has following visible advantage at least:
One, regular as the aluminium alloys.
Two, because good cohesive is arranged, as epoxy resin structural adhesive, need not special surfacing, there is very high intensity the junction, thus easy to make self-evident, in case be damaged, repair also very convenient.
Three, unlike aluminium alloys, be subject to the corrosion of acid medium.As steam of acid rain, sulfur-bearing acids etc.
Fig. 2 is the fine method technological process of production of a kind of length.
With the glass of crossing through coupling agent treatment 1,, that HDPE is coated on it by extruder 2.When fiber bundle passed through extruder 3, the PET blend was coated at skin.Extruder 3 is to reclaim out machine and dispensing functional filler such as antimony oxide by PET, and the spiral of molybdenum bisuphide class inorganic powder supplies with blended material for extension set 5 simultaneously.Granulation in pelleter 6 at last.Pellet mixes in extruder 7 and is extruded into section bar.During by tractor 8, the while customized cut-off.Among the figure 9, be a kind of cross section of section bar.
Embodiment 1 prescription: component title weight percentages of components specification
Terylene refuse 56 contains cotton 33%
HDPE plastic bag refuse 14
20 40/ yarns of glass fiber
Coarse whiting 10 400 orders
This test piece hot strength 35.2Mpa, bending modulus 870Mpa.
Claims (3)
1, a kind of door window frame section bar that is used for, the raw material of this section bar comprise reclaim the terylene refuse, be the shopping plastic bag of main material and the glass fiber of humidification with HDPE.
2, according to the section bar of claim 1, recovery terylene refuse wherein can be pure dacron or the blend fabric that contains other fibers, also can be the PET packaging waste, as PET beverage bottle after using and bottle holder.
3, according to the section bar of claim 1, wherein the shopping plastic bag based on HDPE can contain a spot of LLDPE and PP.
