Description
Den foreliggende oppfinnelse vedrører en elastisk, myk skumplast med et basismateriale som består av oppskummet syntetisk eller naturlig latex eller blandinger av disse, og en armering av cellemateriale. The present invention relates to an elastic, soft foam plastic with a base material consisting of foamed synthetic or natural latex or mixtures thereof, and a reinforcement of cellular material.
Den vedrører også en fremgangsmåte til fremstilling av It also relates to a method for the production of
den elastiske, myke celleplast. the elastic, soft cellular plastic.
Det er kjent å fremstille elastiske, myke skumstoffer It is known to produce elastic, soft foams
ved blanding av et fyllstoff, som består av krystallinsk kal-sitt eller dolomitt i basismaterialet, hvoretter blandingen ekspanderes, dvs. vispes eller eses, inntil det er oppnådd ønsket densitet. Med økende fyllstoffinnhold og økende ekspan-sjon kan produktets pris senkes, men samtidig blir dets trykkfasthetsegenskaper dårligere, slik at kvalitetskravene begren-ser disse forholdsregler. by mixing a filler, which consists of crystalline calcite or dolomite in the base material, after which the mixture is expanded, i.e. whisked or kneaded, until the desired density is achieved. With increasing filler content and increasing expansion, the product's price can be lowered, but at the same time its compressive strength properties become worse, so that the quality requirements limit these precautions.
I noen år har det funnes på markedet små, gassfylte, For some years there have been on the market small, gas-filled,
hule kuler av aluminiumsilikat, såkalte mikrokuler, som utgjør en bestanddel av såkalt flygeaske, som fåes fra visse kullfyrte kraftverk. Disse mikrokuler forekommer i størrelsene ca. 2 00-, 300 y med en veggtykkelse på mellom 3 og 5 y og en volumvekt på 0,3-0,7 g/cm . Mikrokulene er blitt anvendt som vektsenkende middel i herdbare plastmasser, betong etc. hollow spheres of aluminum silicate, so-called microspheres, which form a component of so-called fly ash, which is obtained from certain coal-fired power plants. These microspheres occur in sizes approx. 2 00-, 300 y with a wall thickness of between 3 and 5 y and a volume weight of 0.3-0.7 g/cm . The microspheres have been used as a weight-reducing agent in hardenable plastics, concrete etc.
Formålet med den foreliggende oppfinnelse er å bedre de innledningsvis kjente typer av elastiske, myke skumplaster ved hjelp av nevnte mikrokuler. The purpose of the present invention is to improve the initially known types of elastic, soft foam plastics by means of said microspheres.
Skumplasten ifølge oppfinnelsen er kjennetegnet ved at cellene består av gassfylte, hule mikrokuler av aluminiumsilikat med diameter 200-300 y og er jevnt fordelt i basismaterialet. The foam according to the invention is characterized by the fact that the cells consist of gas-filled, hollow microspheres of aluminum silicate with a diameter of 200-300 y and are evenly distributed in the base material.
Fremgangsmåten kjennetegnes ved at gassfylte, hule mikrokuler av aluminiumsilikat med diameter 200-300 u blandes jevnt i basismaterialet, og at blandingen vispes eller eses til ønsket densitet og deretter vulkaniseres. The method is characterized by the fact that gas-filled, hollow microspheres of aluminum silicate with a diameter of 200-300 u are evenly mixed in the base material, and that the mixture is whisked or kneaded to the desired density and then vulcanized.
Cellene danner en uelastisk forbindelse med den omgivende plast- eller elastomermasse og er stort sett bestemmende for skumplastens trykkfasthetsegenskaper. Det nye stoff utmerkes av at det er betydelig lettere enn kjente .stoffer av til-svarende type og har bedre trykkfasthetsegenskaper, særlig høyere delamineringstrykkfasthet. The cells form an inelastic connection with the surrounding plastic or elastomer mass and are largely decisive for the foam plastic's compressive strength properties. The new fabric is distinguished by the fact that it is significantly lighter than known fabrics of a similar type and has better compressive strength properties, in particular higher delamination compressive strength.
Oppfinnelsen vil i det etterfølgende bli nærmere beskrevet ved hjelp av et utførelseseksempel som dels vedrører fremstilling av en latexblanding ifølge kjente og den nye fremgangsmåte. The invention will subsequently be described in more detail with the help of an embodiment which partly relates to the production of a latex mixture according to known and the new method.
Eksempel 1 ■■ .: ■ Example 1 ■■ .: ■
Fremstilling av latexblanding ifølge en: kjent fremgangsmåte (resept A) og den nye fremgangsmåte (resept B). Preparation of latex mixture according to a: known method (recipe A) and the new method (recipe B).
Blandingen.ble matet kontinuerlig: til en.skumningsmaskin av typen Eur-0,-Matic. hvor luft ble innvispet mekanisk. Resept -B som inneholdt kuler^med en densitet .på ca. 0,4 g/on , ga etter innvisping.av samme luf.tmengde som -i resept A et skum som var ca.. 150 g lettere pr. liter.. The mixture was fed continuously to a Eur-0,-Matic foaming machine. where air was whisked in mechanically. Recipe -B which contained spheres with a density of approx. 0.4 g/on, after whipping in the same amount of air as - in recipe A, gave a foam that was approx. 150 g lighter per liter..
Skummet ble matet videre =til en belegningsmaski-n hvor skummet ved hjelp av valse eller skrape ble strøket på.en bane, f.eks. en tekstilmatte. Banen med skummet- ble for -yulkanisering matet gjennom ovner, med en temperatur, på ca. 150°C. The foam was fed further = to a coating machine where the foam was applied by means of a roller or scraper onto a web, e.g. a textile mat. The web with the foam for -ulcanization was fed through ovens, with a temperature of approx. 150°C.
Den således fremstilte skumplast viste seg ved prøver- The foam plastic produced in this way proved to be
å ha klart- bedre mekaniske egenskaper, f.eks.- høyere de-lamineringsstyrke.. to have clearly better mechanical properties, e.g. higher delamination strength..
Tilsetningsmengden mikrokuler kan variere og utgjør mak-simalt, .60 -vektsprosent...;The amount of added microspheres can vary and amounts to a maximum of .60% by weight...;
