Частиците от твърдо вещество, по-специално от корунд, са подходящи предимно за оцветяващи, намаляващи износването и/или намаляващи изплъзването добавки за керамични глазури, например за керамични подо ви плочки.Particles of solid, in particular corundum, are particularly suitable for coloring, wear-reducing and / or slip-reducing additives for ceramic glazes, for example for ceramic floor tiles.
Description
Покрити с керамична цветни тела частици· от твърдо вещество на оксидна база,метод за тяхното получаване и тяхното приложение предлаганото, изобретение се отнася до· частици от твърдо вещество на оксидна основа,по-специално от корунд,които са покрити с керамични цветни тел а,както и до метод за тяхното получаване.изобретението се отнася освен това до използването на тези частици като оцветяващи,намаляващи износването и награпяваши компоненти,по-специал но в керамични глазури,емайл,лакобояджийски вещества и състави за получаване на покрития.Ceramic colored bodies oxide-based solid particles, process for their preparation and application thereof, the invention relates to oxide-based solid particles, in particular corundum, which are coated with ceramic colored bodies. The invention also relates to the use of these particles as colorants, abrasion reducing agents and build-up components, in particular in ceramic glazes, enamel, paint and coatings. those.
оа подобряването на механичните свойства,по-специално на устойчивостта на износване и на сигурността срещу изплъзване,във силн натоварени повърхности се въвеждат често частици от твърдо вещество. Примери за такива повърхнини са между другото керамични подови настил ки,респективно техните глазури,по-специално за подове в мокри помещения,като обществени или частни бани,или на открито,или подови настилк от други материали,като пластмаси, или изкуствени камъни,които са изложени на същите натоварвания Жато частици от твърдо, вещества за тази цел се използват преди всичко всички фракции от корунд,които за разлика от неоксидните твърди вещества,като твърди метали или силициев карбид могат да се въвеждат в глазури и емайл,оез опасност от протича на смущаващи химични реакции; и при благоприятни цени притежават задовoa the improvement of mechanical properties, in particular wear resistance and slip safety, often entrained solid particles in heavily loaded surfaces. Examples of such surfaces are, inter alia, ceramic flooring, respectively, their glazes, in particular for floors in wet rooms, such as public or private bathrooms, or outdoors, or flooring made of other materials such as plastics or artificial stones, which are exposed to the same loads Jat particles of solid, substances for this purpose are used above all all corundum fractions, which, unlike non-oxide solids, such as solids or silicon carbide, can be introduced into glazes and enamel, the danger of interfering chemical reactions; and at bargain prices they have a behind
лителна твърдост и устойчивост на износване.tensile strength and abrasion resistance.
Недостатък на обичайните търговски фракции, от корунд е,че е тях. са възможни само ограничени оцветявания и соедства за получаван на повърхностни аректи,което води до ограничения при тяхното използване в жилищното строителство,както и в строежа на обществени сгради. Причината за. това се крие в свойствата на тези фракции от корунд, които са оцветени от бяло до кафяво или от сиво до синьо,респективно при специални, видове корунд от розово до рубин и могат да се променял при използването в керамични глазури по време на процеса на изпичане, задоволителни резултати могат да се постигнат следователно само тогава,когато глазурата притежава приблизително същия цвят,с което се стеснява значително цветовата палета и разбира се,изключват се всичка интензивни цветови тонове.Повишаване на количеството на цветните телг в глазурата над обичайната стойност не води до отстраняване на този недостатък,тъй като частиците от корунд в съответствие с тяхната цел трябва да се намират по повърхността на глазурата,а от друга стоана това води до съществено оскъпяване.Също така,силно ограничена е възможността за използване евентуално на средства за образуване на повъ? ностни ещекти,като например напръсквания с различни цветове между гл; зурата и твърдото вещество.The disadvantage of the usual factions of corundum is that it is them. only limited colorings and joints are possible to obtain surface surfaces, which results in restrictions on their use in residential construction and in the construction of public buildings. The reason for. this is due to the properties of those corundum fractions, which are colored white to brown or gray to blue, respectively for special types of corundum from pink to ruby and may change when used in ceramic glazes during the baking process , satisfactory results can therefore only be achieved when the glaze has approximately the same color, which significantly narrows the color palette and, of course, excludes all intense color tones. above normal value does not eliminate this disadvantage, since the corundum particles according to their purpose must be located on the surface of the glaze, and on the other hand, this leads to a significant increase in cost. possibly the means of forming a water pole? nectar, such as sprays of different colors between gl; zuras and solids.
задача на предлаганото изобретение следователно е да се предоставят на разположение частици от оксидно твърдо вешество,които могат да се въвеждат във всякакви оцветени глазури и други повърхности, без да влошават цветовото въздействие и които позволяват разширяване на цветовата палета за получаване на равномерни оцветявания и специални средства за образуване на повърхностни ефекти,като наприме напръсквания,матиране,меланжиране,придаване на мраморен етсект,както и други образци.it is therefore an object of the present invention to make available oxide solid particles which can be introduced into any colored glazes and other surfaces without impairing the color effect and which allow the color palette to be expanded to obtain uniform colors and special means for surface effects such as spraying, matting, melting, marbling, and other specimens.
Тази задача се решава съгласно изобретението чрез покрити с керамични цветни тела частици от твърдо вещество на окси^на база, съдържащи най-малко керамично цветно тяло и най-малко едно средство за свързване.This object is accomplished according to the invention by using oxy-based solid particles coated with ceramic colored bodies containing at least a ceramic colored body and at least one bonding agent.
£еше намерено,че е възможно,частици от твърдо вещество на оксидна база да се получат с покритие от едно или по-вече керамични цветни тела и средство за свързване.It has been found that oxide-based solids may be coated with one or more ceramic colored bodies and a bonding agent.
но този начин могат да се използват добрите механични свойства на частиците от твърдо вещество,без при това да съществуват ограничения в оцветяването или да се намали, броя на възможните средства за получаване на ефекти при тези обекти,в които частиците намират приложение.but in this way the good mechanical properties of the solid particles can be utilized, without, however, being limited in coloring or reducing the number of possible means of obtaining effects in those objects in which the particles find application.
Под керамични цветни тела тук трябва да се разбират получени от /неорганични/ оксиди по време на процеса на изпичане,неорганични съединения /например рутили,шпинели,хромити,алуминати,ферити и. др. подобни/,които се използват като оцветяваща компонента в керамичните глазури и се характеризират с това,че не се разтварят или само слабо се разтварят в керамичните глазури.Ceramic colored bodies are to be understood here as derived from (inorganic) oxides during the firing process, inorganic compounds / eg rutile, spinel, chromite, aluminates, ferrites, etc. similar /, which are used as a coloring component in ceramic glazes and characterized in that they do not dissolve or only slightly dissolve in ceramic glazes.
наред с това,в зависимост от специфичните за прилагането изисквания е възможно използването също и на неорганични пигменти, като например еднофазни или многофазни метални комплекси, метал ни прахове и др.,както и на оцветяващи трити.in addition, depending on the application-specific requirements, it is also possible to use inorganic pigments such as single-phase or multiphase metal complexes, metal powders, etc., as well as staining trites.

Общоизвестно е,че за повърхности,които не са изложени на температури над 300°C,като например боядисани с бои или лакове, повърхнини на пластмаси и бетон,могат да се използват безпроблемно всички керамични цветни тела в смисъла на горната дефиниция три използването на цветни стъкла специално в глазури за плочки се осъществява смесване на стопилка от цветното стъкло с глазурата около ядрото на твърдата частица,което може да доведе отчасти до желан ефект на меланжиране.It is common knowledge that surfaces that are not exposed to temperatures above 300 ° C, such as paints or varnishes, surfaces of plastics and concrete, can be used seamlessly with all ceramic colored bodies within the meaning of the above definition. Glasses specifically in tile glazes mix melted colored glass with the glaze around the core of the solid, which can lead in part to a desired melting effect.
При използването на неорганични пигменти в глазурите,при всеки отделен случай трябва да се опитва доколко е налице неутрално поведение на неорганичните пигменти при изпичане на глазурата.When using inorganic pigments in glazes, in each case, it must be attempted to determine whether there is a neutral behavior of inorganic pigments in the glaze firing.
Като основен материал съгласно изобретението за покритите частици от твърдо вещество на оксидна база се използват поеди всичко алуминиев оксид,циркониев оксид,силициев оксид,шпинели или смеси от тях,в даден случай заедно с обичайните онечиствания и/или добавки като например стабилизатори или помощни средства за синтероване.As the base material of the invention for the coated solid particles on an oxide base, aluminum oxide, zirconium oxide, silica, spinels or mixtures thereof, optionally together with conventional impurities and / or additives such as stabilizers or auxiliaries, are used for sintering.
Особено предпочитан материал е корунд,в частност стопен или синтерован корунд.Particularly preferred material is corundum, in particular fused or sintered corundum.
Големината на частиците на покритите съгласно изобретението частици от твърдо вещество възлиза на 0,03 до· 3 мм,за предпочитане обаче 0,06'до 0,5 мм.исобено предпочитани са тесни ленти с фракции, така както те са описани в FEPA-стандарт 42-D -1984,респективно в 43-D -1984.The particle size of the solids coated according to the invention ranges from 0.03 to · 3 mm, but preferably 0.06 'to 0.5 mm. Particularly preferred are narrow strips of fractions as described in FEPA- standard 42-D -1984, respectively, in 43-D -1984.
поради тяхната големина,покритите частици от твърдото вещест во могат много добре да се преработват,тъй като те са сипливи и не съдържат прах,и поради тази причина не агломерират.because of their size, the coated solids particles can be very well processed as they are loose and free of dust and therefore do not agglomerate.
Те са приложими следователно както при метода на сухо глазиране,така също и по метода обичайното мокро глазиране и могат да се пренасят добре и да се дозират чрез автоматични съоръжения.They are therefore applicable both to the dry glazing method and to the conventional wet glazing method and can be well tolerated and dispensed by automatic means.
Керамичното цветно тяло се използва в количество от 2 до 20 тегловни за предпочитане от 5 до 10 тегловни отнесени към количеството на частиците преди тяхното покриване.Количеството с което следва да се покрият зависи от големината на зърното на цветното тяло,желаната интензивност на оцветяването,дълбочината на оцветяването,както и размера на частиците на твърдото тяло.The ceramic colored body is used in an amount of 2 to 20% by weight, preferably from 5 to 10% by weight, relative to the amount of particles before coating. The amount to be coated depends on the grain size of the colored body, the desired color intensity, the depth of staining as well as the particle size of the solid.
при използването на финни гранулометрични фракции / например Р 220 съгласно FEPA/,кеоамичните глазури могат така да се оцветят,when using fine particle size fractions (for example P 220 according to FEPA), the keoamic glazes can thus be colored,
че да с.е получи впечатление за хомогенно визуално оцветяване.такова каквото се получава при обичайното; оцветявана; на глазура чеез диюектн добавяне на оцветени тела.to give the impression of a homogeneous visual coloration. as is usual; colored; of icing through the addition of colored bodies.
Оказа се обаче,че при използване на покритите съгласно изобретението частици от твърдо вещество е достатъчно значително по-малк количество от цветни тела,за да се постигне същото насищане на цвета . както при обичайното оцветяване на глазурата.! ак а например чоез добавка на 7 тегловни цветни покрити, частици от корунд със съдържание на цветни тела максимално 10 тегловни ^,т.е. максимално 0,7 тегловни % цветни тела,отнесени спрямо общата суха глазурна смес,се постига същото насищане на цвета,както при директна добавка на 5 тегловни % цветни тела към същата глазура.However, when using the coated solids particles, a substantially smaller amount of colored bodies is sufficient to achieve the same color saturation. as with the usual glaze coloring. such as, for example, a chase additive of 7 weighted colored coats, particles of corundum having a colored body content of up to 10 weight%, i.e. a maximum of 0.7% by weight of colored bodies, relative to the total dry glaze mixture, achieves the same color saturation as with the direct addition of 5% by weight of colored bodies to the same glaze.
но този начин става възможно да се намали драстично частта на тежките метали в глазурата,без за това да бъде необходимо да се променят други компоненти на цветното тяло.but this makes it possible to drastically reduce the proportion of heavy metals in the glaze without having to change other components of the colored body.
Като свързващо средство за покриването е подходящо по принцип всяко свързващо средство,което умокря в достатъчна степен,както твърдото вещество,така също и цветното тяло,образува достатъчно здгаво прилепващ слой и не оказва пречещо действие при предвижданото използване на покритите частици,например при изпичане глазурата на плочки.As a coating binder, it is generally suitable for any binder that sufficiently moistens both the solid and the colored body to form a sufficiently rigid adhesive layer and not interfere with the intended use of the coated particles, for example, when baking glazes. on tiles.
предпочитани свързващи средства са силициеви киселини,соли на силициеви киселини,съответно с или без прибавяне на оезцветни глазурни гррити,алуминиев монсиросфат или смеси от тези вещества.особено предпочитани са алкални силикати. / водно стъкло/,като напюимер натриево водно стъкло.preferred binders are silicic acids, salts of silicic acids, respectively, with or without the addition of discolored glazes, aluminum monsyrosphate or mixtures of these substances. Alkali silicates are particularly preferred. (water glass), such as sodium hydroxide glass.

The amount required depends on the specific surface, resp. tively the size of the particles and the viscosity of the solution, respectively of the suspension and the colored bodies.

After applying the colored body, the particles first dry. Further thermal treatment depends very strongly of the desired application and covers a temperature range of
