Description
Technical field
The present invention relates to construction material preparing technical fields, more particularly to a kind of preparation side of bi-component vitrified brick gum
Method.
Background technology
Currently, home decoration, large-scale club, supermarket and building internal and external ornament used by high water absorbing capacity（5%~
10%）Pottery brick, intensity is low, style is single, specification is small, because due to be not suitable for high speed development market need.With this
Meanwhile vitrified tile has been widely used in building decoration because it has the advantages that low water suction, intensity high, specification and wide in variety
Market.
Vitrified tile is being commonly called as polished brick in porcelain character, and vitrified tile is fired according to a certain percentage by quartz sand, mud, then
Bright through polishing but need not polish, surface is smooth bright as glass-mirror, is one kind most hard in all ceramic tiles.Glass
It is a kind of good ornament materials to change brick, is used for interior decoration, has many decorative effects, such as shows noble, firm, beautiful
See and other effects.In current building decoration construction, generally use cement mortar or glue for tile are pasted.Due to vitrified tile
The water absorption rate of itself is less than 5 ‰ so that it is highly difficult when pasting to cement layer surface, and sticking effect is bad, leads to vitrified tile
Easily there is hollowing, obscission when after stickup by itself or outer force effect.Vitrified brick gum can effectively improve vitrified tile
The adhesion strength at the back side and cement layer surface is current most effective interfacial adhesion reinforcing material.
Currently, vitrified brick gum in the market is mainly made of pulvis and liquor two parts, pulvis is by cement, mineral
Gather materials, the pulverulent mixture of organic admixture composition, liquor is by lotion, preservative, antifoaming agent, water and other auxiliary agent groups
At when, use by pulvis and liquor mix according to a certain percentage, for paving in ornament materials such as ceramic tile, vitrified tile, floor tiles
The back side is widely used in the facing decoration places of the buildings such as inside and outside metope, ground, bathroom, kitchen, because it is with adhesion strength
The features such as high, water-fast, freeze-thawing resistant, ageing-resistant performance are good and easy for construction, and be widely used.
However, vitrified brick gum currently on the market after being bonded with vitrified tile, is easy out when by the etch of rainwater
The phenomenon that now falling off.The cold and hot variation of weather also can make cementitious material by the influence deformed, and lead to cementitious material and vitreous
There is parting in brick interface, so as to cause falling off for vitrified tile.
Therefore, developing a kind of vitrified brick gum that can solve above-mentioned performance issue is highly desirable.
Invention content
Present invention mainly solves the technical issues of, for since vitrified tile water absorption rate is low, surface is smooth, leads to vitreous at present
Brick gum pastes difficulty, when by vitrified brick gum and concrete binding, since concrete surface adheres to a large amount of dust, influences vitreous
