Abstract
The invention relates to an interface agent composition, which comprises, by weight, 65-80 parts of water, 0.05-0.5 part of a surfactant, and 20-35 parts of a polymer emulsion dry substance or redispersible polymer latex powder. Compared with the interface agent composition in the prior art, the interface agent composition of the present invention has the advantage of significant improvement of bond strength between the cement-based adhesion mortar and the rock wool and the bond strength between the surface mortar and the rock wool.
Description
Technical field
The application relates to a kind of interfacial agents composition and application thereof, particularly, relates to a kind of interfacial agents composition and is improving the application in cement based adhesive mortar and the cohesive strength between plastering mortar and rock wool.
Background technology
Rock wool is that one is passed through fusing by starting material such as the volcanic rock such as basalt, slag, Wingdale, rhombspar, silica, bauxitic clays, jetted into fiber, fiber becomes cotton piece through collection cotton, and cotton piece is through the goods of the processes such as pendulum, folded pressurization, baking and curing, cutting.Formed in the stage of fiber in winding-up, that sends with winding-up wind also has solidifying agent and water-resisting agent, and they are coated on the surface of every root fiber.Solidifying agent makes numerous fiber crosslinked fixing in the baking and curing stage, forms the goods with intensity.Water-resisting agent makes fiber surface have hydrophobic character.For whole goods, it has hydrophobic character, and the globule can be formed " lotus leaf effect " on its surface, in standard " external wall Surgery therapy asbestos product GB/T25975-2010 ", require that the hydrophobic rate of goods must not be less than 98%.The object of rock wool hydrophobic prevents moisture from entering in asbestos product.
External insulating system for thinly plastered external wall is the system (as shown in Figure 1) that building exterior wall heat preserving is conventional, its way adopts cement-based mortar (this mortar is called adhesive mortar or binding agent, tackiness agent) to be pasted onto on exterior wall by lagging material, be aided with crab-bolt to fix, then (this mortar is called plastering mortar to smear the thick cement-based mortar of one deck 3-5mm at the heat insulation material surface pasted, or finishing mucilage), in the centre of plastering mortar, built-in layer of glass screen cloth strengthens.Because the coat of plaster of this heat-insulation system structured surface is very thin, engineering claim this system be external insulating system for thinly plastered external wall.The performance slightly difference of the two kinds of mortars used in external insulating system for thinly plastered external wall, but all belong to cement-based mortar, hereinafter referred to as cement-based mortar.Obviously, in whole heat-insulation system, cement-based mortar should have enough cohesive strengths with lagging material, otherwise, under the effect of negative blast, float coat can be made to come off (when plastering mortar and lagging material bond deficiency), or lagging material come off (when adhesive mortar and lagging material bond deficiency) from adhesive linkage.
When the lagging material in external insulating system for thinly plastered external wall adopts rock wool, this system just becomes rock wool outer wall outer heat preservation system, or rock wool external insulating system for thinly plastered external wall.This sticking strength is also called tensile bond strength, has detailed regulation about its testing method in standard " molding exterior insulation system for polyphenyl plate thin plastering exterior wall material GB/T29906-2013 ".
Adopt the interfacial agents intensity improved between two interfaces to be the method comparatively commonly used, and in building field, often adopt polymkeric substance as interfacial agents.
But, because existing interfacial agents can not fully enter in the space between rock wool fibers, therefore still there are the needs to the interfacial agents composition improving cement based adhesive mortar and the cohesive strength between plastering mortar and rock wool further.
