Abstract

Building materials such as blocks, building elements, panels, pipes and paving slabs are made by (1) heating a granular mineral material such as sand to a temp. above the m.pt. of a thermoplastic (I) comprising scrap material derived from waste material produced during machining or processing of the (I) or used packaging material; (2) adding the (I) to the heated mineral and mixing to form a pasty material; (3) shaping the paste into the desired form and (4) cooling th eshaped parts to harden the mouldings. Pref. (I) is a hydrocarbon material such as polystyrene foam, polyethylene or polypropylene. The finished prods. contain 1-5 wt%, esp. 1.5-3 wt% of the (I). Process gives useful building prods. from plastics scrap which is usually incinerated causing atmospheric pollution and loss of useful material. The prods. have good mechanical properties, esp. compressive strength comparable with that of concrete.

BOUWMATERIAAL UIT KUNSTSTOFAFVALBUILDING MATERIAL FROM PLASTIC WASTE

De verwerking van grote hoeveelheden afval van thermoplastische kunststoffen geeft steeds" toenemende problemen. Men kan deze stoffen uiteraard in een vuilverbrandingsinstallatie verbranden, doch de warmteopbrengst hiervan is bescheiden, 5 terwijl men geen gebruik maakt van de gunstige materiaaleigenschappen van de thermoplastische kunststoffen.The processing of large amounts of waste from thermoplastic plastics always presents increasing problems. These substances can of course be burned in a waste incineration plant, but the heat yield thereof is modest, while the favorable material properties of the thermoplastic plastics are not used.

Gevonden werd nu, dat de bedoelde af vallen zeer gunstig ge- [' bruikt kunnen worden voor het vervaardigen van bouwmateria- \ len in de vorm van gevormde voorwerpen zoals bouwstenen, 10 bouwelementen, bouwplaten en buizen of van wegdekken, indien men een korrelvormige minerale stof verhit tot een temperatuur boven het smeltpunt van de thermoplastische kunststof, vervolgens in een menginrichting het afval daarmede vermengt tot een homogene stortbare brei verkregen is, deze brei in 15 de gewenste vorm brengt en vervolgens door afkoeling laat vast worden.It has now been found that the said wastes can be used very advantageously for the manufacture of building materials in the form of shaped objects such as building blocks, building elements, building plates and pipes or of road surfaces, if one uses a granular mineral the material is heated to a temperature above the melting point of the thermoplastic plastic material, then the waste is mixed therewith in a mixing device until a homogeneous bulkable knit is obtained, this knit is brought into the desired shape and subsequently allowed to solidify by cooling.

Het op deze wijze verkregen materiaal heeft gunstige mechanische eigenschappen, in het bijzonder een hoge druksterkte en kan worden toegepast op dezelfde wijze als beton.The material obtained in this way has favorable mechanical properties, in particular a high compressive strength, and can be used in the same way as concrete.

20 De korrelvormige minerale stof is bij voorkeur: zand, dat goedkoop en in grote hoeveelheden beschikbaar is. Aangezien κ de werkwijze volgens de uitvinding niet zeer gevoelig is voor de kwaliteit van het zand, kan men van alle mögelijke soorten zand gebruik maken. Dit is met name van belang als 25 men de werkwijze volgens de uitvinding gebruikt voor het aanbrengen van wegdekken. Men kan dan veelal gebruik maken van ter plaatse aanwezig zand, zodat transport over grotere afstanden vermeden wordt. Mocht men gebruik maken van zeezand, dan is voorafgaande ontzilting niet noodzakelijk. Men 30 kan ook gebruik maken van andere minerale materialen, zoals tgemal’en baksteen of- h-oogo-venslakken , “ 8200730 * r - 2 -The granular mineral substance is preferably: sand, which is cheap and available in large quantities. Since the method according to the invention is not very sensitive to the quality of the sand, all kinds of sand can be used. This is particularly important when the method according to the invention is used for applying road surfaces. It is then often possible to use sand present on site, so that transport over greater distances is avoided. If one uses sea sand, prior desalination is not necessary. Other mineral materials can also be used, such as tgemaleen brick or h-eye ooze slag, “8200730 * r - 2 -

Het thermoplastische kunststofafval , dat in de werkwijze volgens de uitvinding wordt toegepast, bestaat bij voorkeur uit een thermoplastisch koolwaterstofpolymeer. zoals polyethyleen, polypropyleen of polystyreen. Bij voorkeur maakt 5 men gebruik van afval,· verkregen bij de mechanische bewerking of verwerking van deze materialen.The thermoplastic plastic waste used in the method according to the invention preferably consists of a thermoplastic hydrocarbon polymer. such as polyethylene, polypropylene or polystyrene. Preferably, use is made of waste obtained from the mechanical processing or processing of these materials.

Men kan echter ook gebruik maken van gebruikte verpakkingsmaterialen zoals bij voorbeeld het .polystyreenschuim,, gebruikt voor het vastzetten van elektrische huishoudelijke 10 apparatuur in de voor de verpakking gebruikte doos of krat.However, it is also possible to use used packaging materials such as, for example, the polystyrene foam, used for securing electrical household equipment in the box or crate used for the packaging.

Afval van isolatieplaten van polystyreen, bekend onder de naam "Tempex" is eveneens zeer geschikt. Tenslotte kan men ook gebruik maken van thermoplastisch foliemateriaa-1, gewonnen door middel van een scheidingsinstallatie voor huisvuil.Waste from polystyrene insulation boards, known under the name "Tempex", is also very suitable. Finally, one can also use thermoplastic film material-1, obtained by means of a household waste separation plant.

15 Bij voorkeur maakt men van een zodanige verhouding van de beide componenten gebruik, dat het gerede materiaal 1-5 gew. %, in het bij zonder · 1,5 tot. 3 gew. % van het thermoplastische materiaal bevat.Preferably, such a ratio of the two components is used that the finished material is 1 to 5 wt. %, in particular · 1.5 to. 3 wt. % of the thermoplastic material.

De temperatuur waarbij de menging van de componenten plaats-20 vindt is- afhankelijk van het smeltpunt van het gebruikte afval. Essentieel is alleen, dat bij de menging een homogene, gemakkelijk verwerkbare en stortbare brei verkregen wordt.The temperature at which the components are mixed depends on the melting point of the waste used. The only essential thing is that a homogeneous, easy to process and pourable knit is obtained during the mixing.

Gewoonlijk zijn temperaturen van 125° tot 250°C. daarvoor . · ' toereikend.Usually temperatures are from 125 ° to 250 ° C. therefor . · 'Adequate.

25 VOORBEELD „ j25 EXAMPLE “j

Zeezand wordt in een menginrichting verhit tot een temperatuur van ca 150°C. Vervolgens wordt per kubieke meter zand 25 kg. afval van polystyreenschuim (isolatieplaten, bekend onder de naam "Tempex") toegevoegd. Het mengen wordt voort-30 gezet tot een goed stortbare brei verkregen is. Deze brei wordt uitgestort en vlak uitgestreken teneinde het wegdek te vormen. Na één uur afkoelen was het wegdek verhard. Na 2 24 uur had het wegdek een druksterkte van 355,5 kg/cm ©(gemiddelde van 4 monsters) verkregen.Sea sand is heated in a mixing device to a temperature of approx. 150 ° C. Then 25 kg per cubic meter of sand. polystyrene foam waste (insulation boards, known as "Tempex") added. Mixing is continued until a good bulkable knit is obtained. This knit is poured out and smoothed out to form the road surface. After one hour of cooling, the road surface was paved. After 24 hours, the road surface had obtained a compressive strength of 355.5 kg / cm @ (average of 4 samples).
