Abstract

A liquid-absorbing material comprises a hardened urea formaldehyde foam comminuted into porous pieces. The surface of the pieces of hardened urea formaldehyde foam and/or the particles of the friction increasing particulate substance is sticky to maintain particulate substance adhered to the surface of said pieces. In a method for manufacturing the liquid-absorbing material pieces of hardened urea formaldehyde foam and/or the particles of the friction increasing particulate substance are sprayed with a heated oil to make the surface of the pieces or the particles, respectively, sticky after the oil having cooled on said surface. The pieces of hardened urea formaldehyde foam and the friction increasing particulate substance are tumbled together to make this substance adhere to the surface of the pieces.

Föreliggande problem Vid utövning av uppfinningen enligt WO-A-80/02846 har man funnit, att det friktionsökande materialet, exempelvis sand, som är inblandat i ureaformaldehydskummet, till följd av skummets skörhet skiljes från skummet och samlas på bottnen av den behållare, i vilken sorbenten lagras och le- vereras, och inte sprides tillsamman med det vätskeabsorbe- rande materialet på den yta, från vilken en kontaminerande vätska skall absorberas medelst det vätskeabsorberande ma- terialet.Present Problems In the practice of the invention according to WO-A-80/02846 it has been found that the friction-increasing material, for example sand, which is mixed into the urea formaldehyde foam, is separated from the foam due to the fragility of the foam and accumulates on the bottom of the container in which the sorbent is stored and delivered, and is not spread together with the liquid-absorbent material on the surface from which a contaminating liquid is to be absorbed by means of the liquid-absorbent material.

Sammanfattning av uppfinningen För lösning av det relaterade problemet avser uppfin- ningen ett vätskeabsorberande material, som innefattar ett härdat ureaformaldehydskum, vilket sönderdelats i porösa stycken, och ett friktionsökande partikulärt ämne, och som kännetecknas av att ytan på styckena av härdat ureaformald- hydskum är klibbig för att hålla kvar det friktionsökande partikulära ämnet på ytan.SUMMARY OF THE INVENTION To solve the related problem, the invention relates to a liquid-absorbent material, which comprises a cured urea formaldehyde foam, which has decomposed into porous pieces, and a friction-increasing particulate matter, and which is characterized in that the surface of the pieces of cured urea formaldehyde foam is to retain the friction-increasing particulate matter on the surface.

Uppfinningen avser också ett förfarande vid fram- ställning av det vätskeabsorberande materialet, vilket kän- netecknas av att styckena av härdat ureaformaldehydskum sprayas med uppvärmd olja för att göra styckena klibbiga efter det att oljan har kallnat på den nämnda ytan, och att styckena med den klibbiga ytan tumlas tillsamman med det friktionsökande partikulära ämnet för att bringa detta att häfta vid den klibbiga ytan på styckena.The invention also relates to a process for producing the liquid-absorbent material, which is characterized in that the pieces of hardened urea formaldehyde foam are sprayed with heated oil to make the pieces sticky after the oil has cooled on said surface, and that the pieces with the sticky the surface is tumbled together with the friction-increasing particulate matter to cause it to adhere to the sticky surface of the pieces.

Ytterligare särdrag hos uppfinningen är definierade i de osjälvständiga patentkraven.Additional features of the invention are defined in the dependent claims.

Detaljerad beskrivning av uppfinningen En sorbent enligt uppfinningen innefattar stycken av härdat ureaformaldehydskum, vilka framställes på det sätt som framgår av WO-A-80/02846 och överdrages med en surfak- tant, såsom såpvatten, för ökning av sorbentens absorp- 10 15 20 524 295 . . . . . . . ososm Ms Gflnozas Sami As\p\o1a Liquid absorbing mazensxwozasools osoeitd sïeïæxïlveziacininåfdåc 31 1 ' _- _; " . _ a 0 n nu en nu o. 3 tionsförmågä. Styckena tumlas sedan, och uppvärmd olja sprayas på styckena under tumlingen. Vilket slags olja som helst kan användas, men företrädesvis är oljan en biolo- giskt sönderdelbar olja, såsom en vegetabilisk olja. Linol- ja bör emellertid undvikas med hänsyn till risken för självtändning. Enligt uppfinningen är det att föredraga att använda rapsolja. Då oljan kallnar på ytan av styckena kvarstår en klibbig yta på styckena.Detailed Description of the Invention A sorbent of the invention comprises pieces of cured urea formaldehyde foam, which are prepared in the manner set forth in WO-A-80/02846 and coated with a surfactant, such as soapy water, to increase the sorbent's absorption. 295. . . . . . . ososm Ms G fl nozas Sami As \ p \ o1a Liquid absorbing mazensxwozasools osoeitd sïeïæxïlveziacininåfdåc 31 1 '_- _; The pieces are then tumbled, and heated oil is sprayed on the pieces during tumbling. Any kind of oil can be used, but preferably the oil is a biodegradable oil, such as a vegetable oil. However, linseed oil should be avoided in view of the risk of self-ignition.According to the invention, it is preferable to use rapeseed oil.When the oil cools on the surface of the pieces, a sticky surface remains on the pieces.

Därefter tumlas de klibbiga styckena av formaldehyd- skum tillsamman med ett partikulärt friktionsökande ämne, såsom sand, aska, torr lera eller något liknande partiku- lärt ämne, vilket häftar vid den klibbiga ytan på styckena.Then the sticky pieces of formaldehyde foam are tumbled together with a particulate friction-increasing substance, such as sand, ash, dry clay or some similar particulate matter, which adheres to the sticky surface of the pieces.

Den sålunda preparerade sorbenten packas därefter i behål- lare under hermetisk förslutning.The sorbent thus prepared is then packed in containers under hermetic closure.

Då en yta har kontaminerats genom råolja, dieselolja, eller någon annan fet vätska, som gör ytan hal, sprides sorbenten över den kontaminerade ytan och absorberar ome- delbart vätskan och ökar samtidigt friktionen hos ytan till följd av förekomsten av sand eller något liknande partiku- lärt ämne i ändamål att undvika risk för att personer hal- kar, då de gár pà ytan, eller risk för att fordon sladdar på en kontaminerad vägyta. n annou-When a surface has been contaminated by crude oil, diesel oil, or any other greasy liquid that makes the surface slippery, the sorbent spreads over the contaminated surface and immediately absorbs the liquid while increasing the friction of the surface due to the presence of sand or similar particles. learned substance for the purpose of avoiding the risk of people slipping when walking on the surface, or the risk of vehicles skidding on a contaminated road surface. n annou-
