The specific embodiment
Embodiment 1
Shown in Fig. 1 and Fig. 2 a to Fig. 2 d, the utilization of preferred embodiment 1 of the present invention is recycled the waste and is the method for manufacturing elastic foam of material, its first step is for reclaiming 100: be the discarded object that will comprise materials such as rubber, plastic cement, fiber and metal is reclaimed, and footwear such as sport footwear for example.
Second step of the present invention is for pulverizing 110: utilize a known shredding machine 10 that discarded object (sport footwear) is ground into chip.After the discarded object that reclaims is chopped into chip, though still having impurity can't completely separate, but the chip that heterogeneity constitutes can be for making an addition in the expanded material and as inferior raw material, wherein, can be used as the elasticity adjustment material of foaming raw material based on the discarded object chip of elastomeric material, then can be used as the hardness adjustment material of foaming raw material based on the discarded object chip of plastic material, and can be used as the bridging agent or the reinforcing agent of foaming raw material based on the discarded object chip of fibrous material, the abrasion performance and the weight that can be used as foaming raw material based on the discarded object chip of metal material are adjusted material, use and need not be cleaned or separate as there being the grease composition also can be used as softening agent in the salvage material.
Third step of the present invention is that layering separates 120: be to utilize a container 14 of putting on the conveyer belt 12 of a conveying equipment to accept, hold the discarded object chip that pulverized by shredding machine, can utilize the vibrations that process was produced of these conveyer belt 12 transport boxs 14, the discarded object chip that makes heterogeneity forms the state that layerings separate in container 12 automatically according to the difference of proportion.Certainly, also can utilize magnetic force absorption, magnetic field and mode such as sieve that the discarded object chip of heterogeneity is separated according to the difference AUTOMATIC ZONING of proportion.
The 4th step of the present invention is that raw material mixes 130: the discarded object chip of choosing predetermined composition makes an addition in the raw materials such as elastomeric material, blowing agent and utilizes a known mixer 22 to be stirred, mix appropriate time.To make elastic foams such as shoe-pad, sports pad and yoga mat is example, this elastomeric material can be natural rubber (NR), synthetic rubber (PU), poly-ammonia ethene (PVC), polyethylene (PE) or styrene butadiene ribber (SBR) elastomeric material, this blowing agent can be organic foaming agent, can select different proportion discarded object chip based on materials such as rubber, plastic cement, fiber or metals according to the setting of elastic foam physical property as for the discarded object chip.
The 5th step of the present invention is a compressing tablet 140: utilize a known signature sheet machine (not shown) that mixed raw material is pressed into sheet foaming material 16.
Final step of the present invention is a foaming 150: utilize a known sulphur foam box 18 that adds sheet to be foamed material 16 is added sulphur, foaming is elastic foam 20.
Secondly, for avoiding the discarded object chip to contain the hygienic issues that bacterium causes elastic foam to use, this layering separates 120 and mixes with raw material and more to include a sterilisation step 121 between 130 steps, be to utilize high temperature that the discarded object chip is given sterilization processing, or the interpolation bactericide give sterilization processing with the discarded object chip in raw material.
Utilization of the present invention is recycled the waste and is the method for manufacturing elastic foam of material, its gas pressure that is produced in the time of can utilizing blowing agent to play chemical change bonds together discarded object chip and elastomeric material, with use, the more environmental protection that can omit sticker, and, discarded object chip after the recycling does not need to be separated into fully single material, can make an addition in the expanded material raw material as elastic foam, can be fully with the discarded object recycling, to reduce quantity of refuse and effectively to reduce the recycling cost.
Moreover, the present invention more can add with rubber according to the setting of elastic foam physical property, plastic cement, material such as fiber or metal is main different proportion discarded object chip, for example, desire to make this elastic foam more flexible, can improve discarded object chip addition based on elastomeric material, and if desire improves the hardness of this elastic foam, can increase discarded object chip consumption based on plastic material, and if desire to make more abrasion performance or adjust its weight of this elastic foam, can improve discarded object chip addition based on metal material, use and need not be cleaned or separate if there is in the salvage material grease composition also can be used as softening agent, can use the discarded object chip as expanded material and adjust the usefulness of elastic foam rerum natura.
Embodiment 2
As shown in Figure 3, recycle the waste for the utilization of preferred embodiment 2 of the present invention and to be the method for manufacturing elastic foam of material, according to method for making of the present invention also can be made into possess different rerum naturas, the multilayer pad of soft durometer characteristic, the difference of itself and above-mentioned method for making mainly is to implement between compressing tablet and the foaming step following steps:
Softening handle 160: the sheet material surface of foaming is imposed heat treated, and heating-up temperature is 150 ℃ to 250 ℃, or sheet foaming material surface is coated in the surface softening agent is imposed softening the processing.
Surperficial material after will fitting again and sheet foaming material are sent into and are added foaming in the sulphur foam box, and this surface material and sheet foaming material can combine by the gas pressure that blowing agent produced.
As from the foregoing, generally comprise the discarded object (is example with the sport footwear) of materials such as rubber, plastic cement, fiber and metal, because of its material in conjunction with tight, be difficult for separating, if it is split, then various because of sport footwear kind, model with machine, be difficult for automation and handle, artificial treatment then must expend suitable manpower and time, therefore, even the sport footwear raw material is callable material, all very few in the past the recovery very be unfortunately, and the present invention can pulverize it, layering separates, can reclaim use fully, to make elastic foam.Certainly, based on the discarded object chip of fibrous material except the bridging agent that can be used as foaming raw material, more but decrement is used the bridging agent that known expanded material adopts, secondly, discarded object chip based on plastic material is adjusted the material except the hardness that can be used as foaming raw material, more can make an addition in the plastic cement flowerpot raw material and use, and can make an addition to the usefulness of automobile-used rubber slab or PU runway raw material based on the discarded object chip of elastomeric material.
In sum, utilization provided by the present invention is recycled the waste and is the method for manufacturing elastic foam of material, it can make the discarded object chip after the recycling not need to be separated into fully single material, can make an addition in the expanded material raw material as elastic foam, can be fully with the discarded object recycling, to reduce quantity of refuse and effectively to reduce the recycling cost, and, its gas pressure that is produced when utilizing blowing agent to play chemical change can bond together discarded object chip and elastomeric material, can omit the use of sticker, more environmental protection.
