The neutral mosaic adhesive is high in adhesive strength, prevents the hollowing and falling phenomena, and is suitable for sticking tiles and the mosaics, and particularly suitable for sticking the glass mosaics indoors.
Description
Technical field
The present invention relates to a kind of tackiness agent, particularly a kind of Neutral mosaic adhesive, belong to the matrix material technical field in building trade.
Background technology
Mosaic has another name called mosaic tile, and be a kind of building decoration material that can be spliced into various pattern of sheet, be widely used in house ornamentation toilet metope, ground, the positions such as swimming pool, mosaic exquisiteness is small and exquisite, and pattern is changeable, has multiple combination mode, personalized pure.The production of mosaic normally one piece of block is processed mosaic material paste on base material, become the finished product of, the existing material be applied on mosaic mainly contains pottery, stone material, glass (comprising hot melt glass and crystal glass), metal, timber, shell, corium, resin etc., flourish along with mosaic in recent years, the mosaic product of various material emerges in an endless stream, and applied environment is also more and more extensive.Glass Mosaic is the maximum mosaic of current usage quantity.
The tackiness agent that mosaic mosaic tile adopts the notched scraper of 3mm*3mm or 4mm*4mm specification to be stirred adding water when paving is criticized and is scraped on basal plane, be carded to dentate stripe again, being rubbed by mosaic is pressed on tackiness agent, after solidification, selects suitable spackling to carry out joint filling process.The paving of traditional glass Mosaic is generally adopt cement or cement-based adhesive, and cement can produce calcium hydroxide in hydration process, and hydrated product is strong basicity.For the glass Mosaic of goldleaf, minute surface, plating, cold spray one class, because it is without high-temperature fusion, be linked by glue between the color layers of mosaic material and glass coating, once run into acid and alkali substance be easily oxidized blackening, thus lose decorative effect.Therefore, when using the tackiness agent paving glass Mosaic of cement or cement based, the strong base substance that hydrated cementitious produces acts on glass Mosaic, not only can affect decorative effect, also can affect the glass Mosaic life-span.
The whiteness of the tackiness agent usually made with the gelling material of common white cement is not high, therefore, when adopting this type of tackiness agent to paste bottoming, cannot set off out the beautiful color of glass Mosaic and moulding.
