Description
Technical field
This application involves a kind of interfacial agents composition and its applications, and in particular, to a kind of interfacial agents composition and its
Improve the application in the adhesion strength between cement base adhesive mortar and decorative mortar and rock wool.
Background technique
Rock wool is a kind of by the raw material such as the igneous rock such as basalt, slag, lime stone, dolomite, silica, bauxite process
It melts, be blown into fiber, fiber becomes cotton piece by collection cotton, and cotton piece is through techniques such as pendulum, discounting pressurization, baking and curing, cuttings
The product being process.In the stage that blowing forms fiber, also curing agent and the waterproofing agent sent out with blowing wind, it
Be coated on the surface of every fiber.Curing agent fixes numerous fiber crosslinkings in the baking and curing stage, and being formed has intensity
Product.Waterproofing agent makes fiber surface have hydrophobic character.For entire product, with hydrophobic character, droplet is in its table
Face will form " lotus leaf effect ", require product in standard " external wall external thermal insulation with asbestos product GB/T25975-2010 "
Hydrophobic rate cannot be less than 98%.The purpose of rock wool hydrophobic is to prevent moisture from entering in asbestos product.
External insulating system for thinly plastered external wall is the common system of building exterior wall heat preserving (as shown in Figure 1), and way is to use
Thermal insulation material is pasted on exterior wall by cement-based mortar (mortar is known as adhesive mortar or binder, adhesive), is aided with anchor
Bolt is fixed, and the cement-based mortar (the mortar referred to as plastering sand of one layer of 3-5mm thickness is then smeared in the heat insulation material surface pasted
Slurry or finishing mucilage), enhance in layer of glass screen cloth built in the centre of decorative mortar.Due to this heat-insulation system structure
Make a list face coat of plaster it is very thin, this system is referred to as external insulating system for thinly plastered external wall in engineering.In thin plastering exterior wall external thermal insulation
The performance slight difference of two kinds of mortars used in system, but belong to cement-based mortar, hereinafter referred to as cement-based mortar.It is aobvious
So, cement-based mortar should have enough adhesion strengths with thermal insulation material in entire heat-insulation system, otherwise, in the effect of negative wind pressure
Under, can make float coat fall off (when decorative mortar and thermal insulation material bonding insufficient) or thermal insulation material fall off from adhesive layer (when
When adhesive mortar and insufficient thermal insulation material bonding).
When the thermal insulation material in external insulating system for thinly plastered external wall uses rock wool, which just becomes protects outside rock wool outer wall
Warm system or rock wool external insulating system for thinly plastered external wall.This sticking strength is also known as tensile bond strength, about its test
Method has detailed regulation in standard " molding exterior insulation system for polyphenyl plate thin plastering exterior wall material GB/T 29906-2013 ".
Improving the intensity between two interfaces using interfacial agents is more common method, and in the field of construction frequently with poly-
Object is closed as interfacial agents.
However, there are still right since existing interfacial agents can not be well into the gap between rock wool fibers
Further increase the needs of the interfacial agents composition of the adhesion strength between cement base adhesive mortar and decorative mortar and rock wool.
Summary of the invention
