Description
A találmány hidrofil, porszerű ataktikus polipropilén készítmény előállítására vonatkozik.The present invention relates to a hydrophilic powdery atactic polypropylene composition.
Ismeretes az. hogy a polipropilén-gyártás mellékterméke az ataktikus vagy amorf polipropilén, amelynek részaránya a polipropilénre számítva általában 5-14%. Az ataktikus polipropilén a nem vulkanizált kaucsukhoz hasonló, nem kristályos anyag, molekulasúlya 25.000-60.000 között változik. Az ataktikus polipropilén számos termékkel összefér. ! így többek között ásványi olajokkal, poliizobutilén nel. butilkaucsukkal. nyers bitumennel. Számos kísérlet történt a számottevő mennyiségben képződő ataktikus polipropilén hasznosítására. Az egyik hasznosítási lehetőség a bitumen- és olajipar, ahol fuga- 1 kitöltő és tapasztó masszák, bitumenes lakkok, kittek, kenőanyagok és olajok módosítására szolgál, a másik fontos alkalmazási terület az építőipar, ahol ásványi töltőanyagokkal elkeverve hangszigetelő, vízelzáró, tömítőanyag, homlokzatvédő bevonatok 2 komponense, egyéb kötőanyagként szolgálhat.It is known. the by-product of polypropylene production is atactic or amorphous polypropylene, which generally has a proportion of 5 to 14% by weight of polypropylene. Atactic polypropylene is a non-crystalline material similar to non-vulcanized rubber and has a molecular weight ranging from 25,000 to 60,000. Atactic polypropylene is compatible with many products. ! For example, with mineral oils such as polyisobutylene. butyl rubber. with raw bitumen. Many attempts have been made to utilize atactic polypropylene in significant quantities. One of the applications is the bitumen and oil industry, where joints are used for modifying filler and adhesive masses, bituminous varnishes, putty, lubricants and oils, the other important application is the construction industry, where mixed with mineral fillers, soundproofing, 2 components, can serve as other binders.
Az ataktikus polipropilén ipari felhasználásának jelentős akadálya, hogy nagy tömbökben kapható, mechanikai darabolása, beolvasztása viszonylag nagy energia ráfordítást igényel. Emiatt a műanyagiparban sok esetben nem hasznosítható melléktermékként kezelik, amelynek megsemmisítése külön problémát okoz. A javasolt alkalmazás területek ellenére az ataktiKUs polipropilén rendszeres hasznosításának technológiája nincs kidolgozva.A major obstacle to the industrial use of atactic polypropylene is that it is available in large blocks and requires relatively large amounts of energy to mechanically cut and melt. As a result, in the plastics industry, it is often treated as a by-product which cannot be utilized, and its disposal poses a particular problem. Despite the proposed areas of application, the technology for the regular utilization of ataktiKUs polypropylene is not developed.
A találmány egyik célkitűzése az ataktikus polipropilén porszerű alakban történő' előállítása, másik fontos célkitűzés a termék hidrofil tulajdonságainak kialakítása, amellyel lehetővé válik az alkalmazás5 területek bővítése főként az építőiparbanIt is an object of the present invention to provide atactic polypropylene in powder form, and another important object is to provide hydrophilic properties of the product which enable the application areas to be expanded, particularly in the construction industry.
A találmány tehát olyan hidrofil, porszerű ataktikus polipropilén készítmény előállítására vonatkozik. amely fő tömegében 25 000—60 000 molekulasúlyú polipropilént tartalmaz.The invention thus relates to the preparation of a hydrophilic powdery atactic polypropylene composition. Containing, by weight, 25,000 to 60,000 molecular weight polypropylene.
Azt találtuk, hogy ha az ataktikus polipropilén olvadékban in situ dikalcium-szilikátot állítunk elő. akkor a két anyag fizikai keverékéből önporló tulajdonságú új készítmény képződik, amely hidrofil és porszerű állapotú. A polipropilén dikalcium-szilikát5 -monohidrát tartalma következtében porszerű állapotát megtartja, állás közben sem agregálódik. homogén marad, víztartalmú rendszerekkel összefér és azokba könnyen bedolgozható.It has been found that dicalcium silicate is produced in situ in atactic polypropylene melt. then the physical mixture of the two materials forms a new composition with a self-pollinating property which is hydrophilic and powdery. Due to its content of dicalcium silicate5 monohydrate, polypropylene retains its powdery state and does not aggregate on standing. it remains homogeneous, compatible with water-based systems and easy to incorporate into them.
A találmány szerint előállított új készítmény 0 tehát 40-60 tömegszázalék 25 000-60 000 molekuiasúlyú ataktikus polipropilént. 15—25 tömegszázalék dikalcium-szilikát-monohidrátot. 2-5 tömegszázalék sztearinsav, olajsav, palmitinsav. ipari minőségű vegyes zsírsav alkálifémsóját. 20-40 tö5 megszázalék vizet és adott esetben 4-8 tömegszázalék alkáliférn-hidroxidot. előnyösen nátrium-hidroxidot tartalmaz. Az ipari minőségű vegyes zsírsav növényi olajok vagy állati zsírok bontásával, adott esetben desztillálással készített zsírsavak keverékéből 0 áll.Thus, the novel composition of the present invention is 40 to 60% by weight of atactic polypropylene having a molecular weight of 25,000 to 60,000. 15 to 25% by weight of dicalcium silicate monohydrate. 2-5% by weight of stearic acid, oleic acid, palmitic acid. industrial grade mixed alkali metal salt of fatty acids. 20-40% by weight of water and optionally 4-8% by weight of alkali metal hydroxide. preferably containing sodium hydroxide. Industrial grade mixed fatty acids consist of a mixture of fatty acids produced by the decomposition of vegetable oils or animal fats, optionally by distillation.

A találmány szerinti eljárás hidrofil, porszerű ataktikus polipropilén készítmény előállítására abban foglalható össze, hogy 15-25 tömegszázalék nátrium- vagy kálium-szilikát előmelegített vizes oldatához keverés közben 40-60 tömegszázalék, 5 25 000-60 000 molekulasúlyú ataktikus polipropilén olyan olvadékát adjuk hozzá, amelyhez adagolás előtt 2-5 tömegszázalék sztearinsav, olajsav, palmitinsav, ipari minőségű vegyes zsírsav alkálifémsóját adagoltuk. A keverékhez a keverhető konzisztenst 10 fenntartására kívánt mennyiségű vizet és a nátriumvagy kálium-szilikátra számítva 1,1-1,2 sztöchiometrikus arányban mészhidrát vagy oltottmész alakjában kalciumhidroxidot adagolunk majd az elegyet lehűlni hagyjuk. 15The process of the present invention for the preparation of a hydrophilic powdery atactic polypropylene composition comprises adding to a preheated aqueous solution of 15-25% by weight of sodium or potassium silicate, 40-60% by weight of a melt of atactic polypropylene having a molecular weight of 25,000-60,000. to which is added 2-5% by weight of alkali metal salt of stearic acid, oleic acid, palmitic acid, industrial grade mixed fatty acid. The mixture may be mixed with the desired amount of water to maintain a consistent 10 and sodium or potassium silicate, calculated and then allowed to cool hydrated lime or slaked lime in the form of calcium hydroxide is added in a stoichiometric ratio from 1.1 to 1.2. 15
A találmány szerinti készítmény por alakú, emiatt olvadék halmazállapotú rendszerekhez (aszfalt. bitumenes kittek, bevonó bitumenek) való hozzáadása nem teszi szükségessé a helyszínen 20 történő felolvasztást, mivel a porszerű készítményt keverés közben lehet meleg olvadékba beadagolni és a keverést a homogenizálásig folytatni. Ez rendkívül leegyszerűsíti a nehezen kezelhető, tömb alakban rendelkezésre álló ataktikus polipropilén felhaszná- 2’5 lását. A készítmény hidrofil tulajdonsága számottevő előny, cementtel a készítmény jól összefér, a készítmény cementhabarcsba, betonba, mészhabarcsba, vízüveges habarcsokba könnyen bekeverhető.The composition of the invention is in powder form, therefore, the addition of molten systems (asphalt, bituminous putty, coating bitumens) does not require on-site thawing as the powdered composition can be added to the hot melt with mixing and continued until homogenized. This greatly simplifies the use of hard-to-handle, atactic polypropylene in block form. The hydrophilic property of the composition is a significant advantage, it is well compatible with cement and can be easily mixed into cement mortar, concrete, lime mortar and water glass mortar.
A készítmény előállítását az alábbi kiviteli példákban szemléltetjük:The preparation of the composition is illustrated in the following embodiments:
A 70%-nyi száraz termék anyagösszetétele a következő:The composition of the 70% dry product is as follows:
ataktikus polipropilén: 69,5% kalciumszilikát: 24,3% nátriumsztearát: 2,0% nátriumhidroxid: „ 4.2%atactic polypropylene: 69.5% calcium silicate: 24.3% sodium stearate: 2.0% sodium hydroxide: “4.2%
A készítmény nagy kalciumszilikát-tartalma miatt nem gyullad meg, önkioltó tulajdonságú. Nyílt láng hatására a termék összeolvad és elfolyósodik. A készítmény a cementhez és a gipszhez hasonlóan szállítható és tárolható.Due to its high calcium silicate content, the product is non-flammable and self-extinguishing. The product will merge and liquefy when exposed to an open flame. The product can be transported and stored like cement and gypsum.
2. példaExample 2
Mindenben az 1. példa szerint járunk el, azonban sztearinsav helyett olajsavat vagy palmitinsavat adagolunk és a beadagolt anyagok mennyiségét úgy választjuk meg, hogy a 70%-nyi száraz termék összetétele a következő:All were carried out in the same manner as in Example 1, except that oleic acid or palmitic acid was added instead of stearic acid and the amount of added materials was chosen so that 70% of the dry product had the following composition:
ataktikus polipropilén: 80% kalciumszilikát: 16% nátriumsztearát: 1% nátriumhidroxid: 3%atactic polypropylene: 80% calcium silicate: 16% sodium stearate: 1% sodium hydroxide: 3%

Fűthető Z-karú gyúrógépben 90 kg 36 Be°-os normál vizüveg oldatot 80-90 °C-ra felmelegítünk. A párolgási veszteséget vízzel pótoljuk. A berendezés felett elhelyezett fűthető és keverővei ellátott tartályban az ataktikus polipropilént (gyűrűs- golyós lágyuláspontja: 150°C) megolvasztjuk és 145 kg polipropilénhez 5 kg 70 °C olvadáspontú sztearinsavat adagolunk.In a heated Z-arm kneading machine, 90 kg of 36 ° C standard water glass solution is heated to 80-90 ° C. The evaporation loss is replaced by water. In a heated and agitated container above the apparatus, atactic polypropylene (annular ball softening point: 150 ° C) is melted and 5 kg of stearic acid, m.p. 70 ° C, are added to 145 kg of polypropylene.
A polipropilén olvadékot állandó keverés közben az előmelegített vízüvegoldathoz adagoljuk, olyan ütemben, hogy a keverék hőmérséklete a 100°C-t gyorsan elérje. Ehhez kb. 1 liter/másodperc adagolási sebesség szükséges. A polipropilén adagolása után a keveréket homogenizáljuk, az elpárolgó víztartalmat pótoljuk. A vízadagoláskor a keverék hőmérséklete rendszerint csökken. A homogén elegyhez állandó keverés közben 30 kg mészhidrátport adagolunk, amikor megkezdődik a kalciumszilikát képződése, mely jelentős térfogatnövekedéssel és vízfelvétellel jár. A reakció eredményeként képződött laza térfogatú, lehűlés után porszerűen széteső termék összetétele a következő:The polypropylene melt is added to the preheated water glass solution with constant stirring so that the temperature of the mixture reaches 100 ° C rapidly. Approx. A feed rate of 1 liter / second is required. After the addition of the polypropylene, the mixture is homogenized and the evaporated water content is replenished. The temperature of the mixture usually decreases with the addition of water. To the homogeneous mixture is added 30 kg of lime hydrate powder with constant stirring, when the formation of calcium silicate begins, which results in significant volume increase and water uptake. The reaction product formed as a result of the reaction, having a loose volume and disintegrating in powder form upon cooling, has the following composition:
3. példaExample 3
Mindenben az 1. példa szerint járunk el. azonban sztearinsav helyett ipari minőségű vegyes zsírsavat adagolunk, amelyet növényi olajok bontásával, majd a kapott termék desztillációjával állítunk elő. A 40 reakció eredményeként képződő termék laza térfogatú és lehűlés után porszerűen széteső anyag.In each case, the procedure of Example 1 was followed. however, instead of stearic acid, an industrial grade mixed fatty acid is added, which is obtained by breaking down vegetable oils and then distilling the resulting product. The product formed as a result of reaction 40 has a loose volume and is a powdery decomposition material upon cooling.
