Description
Technical field
The present invention relates to a kind of tackiness agent, particularly a kind of neutral mosaic tackiness agent, belong to the matrix material technical field in building trade.
Background technology
Mosaic has another name called mosaic tile, is a kind of building decoration material that can be spliced into various patterns of sheet, is widely used in house ornamentation toilet metope, ground, the positions such as swimming pool, and the mosaic exquisiteness is small and exquisite, and pattern is changeable, and the multiple combination mode is arranged, personalized pure.The production of mosaic normally a piece is processed the mosaic material paste on base material, become one finished product, 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 materials emerges in an endless stream, and applied environment is also more and more extensive.Glass Mosaic is the mosaic of current usage quantity maximum.
The mosaic mosaic tile adopts the notched scraper of 3mm*3mm or 4mm*4mm specification will add tackiness agent that water is stirred and criticizes and scrape on basal plane when paving, be carded to again dentate stripe, mosaic is rubbed and is pressed on tackiness agent, after solidifying, select suitable spackling to carry out the joint filling processing.The paving of traditional glass Mosaic is generally to 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 of it, without crossing high-temperature fusion, between the color layers of mosaic material and glass coating, by glue, connect mutually, once run into the easy oxidation blackening of acid and alkali substance, thus decorative effect lost.Therefore, while using the tackiness agent paving glass Mosaic of cement or cement based, the highly basic material 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 of usually making with the gelling material of common white cement is not high, therefore, while adopting this type of tackiness agent to paste bottoming, can't set off out the beautiful color of glass Mosaic and moulding.
