Abstract

The invention discloses elastic crack-resistant insulation putty for an external thermal insulation system of a rockwool panel external wall. The putty is matched with enhanced leveling insulation mortar, thus a crack-resistant protective coating of the system can be eliminated. According to the putty, cement and re-dispersible polymer powder are used as film-forming materials, small vitrified balls and small hollow fly ash balls are used as insulation packing, silica powder is adopted as a reinforcing material, ferric trichloride, ferrous chloride and the like are used as reactive waterproof agents, bentonite is adopted as a thixotropic material, and methyl cellulose ether is adopted as a water-retaining material. The elastic crack-resistant insulation putty consists of the following components in percentage by mass: 28.0%-50.0% of the cement, 5.0%-15.0% of the re-dispersible polymer powder, 30.0%-60.0% of the small vitrified balls, 8.0%-16.0% of the small hollow fly ash balls, 2.0%-8.0% of the silica powder, 0.5%-2.0% of the ferric trichloride, 0.5%-1.5% of the ferrous chloride, 0.2%-1.0% of aluminum chloride, 4.0%-8.0% of the bentonite and 2.5%-7.0% of the high-viscosity methyl cellulose ether.

Description

A kind of elasticity cracking resistance heat preservation putty that is used to not have cracking resistance protective layer rock cotton board external thermal insulation system
Technical field:
Patent of the present invention belongs to a kind of supplementary material of External Thermal Insulation System, it specifically is a kind of elasticity cracking resistance heat preservation putty that is used for the rock cotton board external thermal insulation system, this putty and the supporting use of enhancement type levelling thermal insulation mortar, criticize the surface that is coated in enhancement type levelling thermal insulation mortar, can make the rock cotton board external thermal insulation system not need to be provided with again the cracking resistance protective layer.
Background technology:
In the structure of rock cotton board external thermal insulation system, if use general building heat-insulating mortar or adhesive powder-polystyrene granule thermal insulation mortar levelling, then in the system cracking resistance protective layer must be set, this can bring system's deadweight to increase, safety of structure and weather resistance are affected adversely, and adhesive powder-polystyrene granule thermal insulation mortar can make system produce problems such as fire safety.The elasticity cracking resistance heat preservation putty and the enhancement type levelling thermal insulation mortar of patent of the present invention are used, can eliminate these problems by the cracking resistance protective layer of cancellation system.But if use common heat preservation putty, then or can be because physical and mechanical properties such as the intensity of common heat preservation putty, splitting resistance, snappiness are poor, perhaps can be owing to the thermal and insulating performance of common heat preservation putty is bad, perhaps can be owing to reasons such as physical and mechanical property were both poor, thermal and insulating performance is also bad, make the performance of putty can not satisfy the requirement of cancellation system cracking resistance protective layer, must use the elasticity cracking resistance heat preservation putty of patent of the present invention.
The patent of invention content:
In order to overcome in the rock cotton board external thermal insulation system structure because of the problem that the cracking resistance protective layer is brought is set, patent of the present invention provides a kind of elasticity cracking resistance heat preservation putty, this putty has physical and mechanical property and thermal and insulating performances such as good intensity, splitting resistance, snappiness, when it and elasticity cracking resistance heat preservation putty are used, in the rock cotton board external thermal insulation system, just no longer need to use the cracking resistance protective layer.
Patent of the present invention solves its technical problem and adopts following technical scheme:
By cement and the compound filmogen of redispersible polymer toner (latex powder) as elasticity cracking resistance heat preservation putty; With glass bead and coal fly ash hollow micro bead is the light heat-insulating filler; With silica flour is that inorganic exciting strengthens the density material, and iron trichloride, iron protochloride and aluminum chloride are response type water-resisting agent material; With the wilkinite is that thixotropic materials, high viscosity methyl cellulose ether are water-keeping material.These material mixing evenly are mixed with elasticity cracking resistance heat preservation putty.
The prescription of described elasticity cracking resistance heat preservation putty is (quality %):
Cement 28.0~50.0; Latex powder 5.0~15.0; Glass bead 30.0~60.0; Coal fly ash hollow micro bead 8.0~16.0; Silica flour 2.0~8.0; Iron trichloride 0.5~2.0; Iron protochloride 0.5~1.5; Aluminum chloride 0.2~1.0; Wilkinite 4.0~8.0; High viscosity methyl cellulose ether 2.5~7.0.
Described cement is that strength grade is 42.5 grades and above building industry general cement commonly used; Described latex powder is that second-order transition temperature is-5 ℃ and following VAE and modification VAE class latex powder; Described glass bead is that performance meets the II series products among the building material industry standard .JC/T1042 " expanded and vitrified small ball "; Described coal fly ash hollow micro bead is the tiny balloon material of the surperficial vitreous of sorting from flyash; Described iron trichloride, iron protochloride and aluminum chloride are general industrial chemicals; Described wilkinite is the sodium bentonite commonly used that is used for the coating thixotropic thickening agent; Described high viscosity methyl cellulose ether is the high viscosity type product of viscosity in 150000cps~250000cps scope; Described silica flour is for producing the superfine powder of collecting the flue dust of silicon steel and ferrosilicon from steel mill and ferroalloy works.
Above formula materials is mixed, promptly become Elastic reactance and split heat preservation putty.
The beneficial effect of patent of the present invention is: two kinds of different light fillers of size of glass bead and coal fly ash hollow micro bead, in putty membrane, can form close-packed mutually, and make the compact structure of elasticity cracking resistance heat preservation putty film and have lower dry density; Iron trichloride and iron protochloride can generate ferric hydroxide colloid with the cement reaction, aluminum chloride can impel the gelinite in the hydrated cementitious product to increase, form fine and close cement stone, form interpenetrating(polymer)networks with the polymer resin components after the latex powder water-dispersion, parcel, bonding light filler improve the putty film strength and reduce water-intake rate; And the latex powder of higher dosage can improve the tensile bond strength of elasticity cracking resistance heat preservation putty, and gives the elasticity of putty membrane necessity; The strong thixotropy that wilkinite produces gives putty good batch being coated with property; The water retention that the high viscosity methyl cellulose ether provides then makes putty have the time of drying of satisfying construction requirement; Silica flour can improve elasticity cracking resistance heat preservation putty film strength and water permeability resistance; Below in conjunction with embodiment patent of the present invention is described further.
Embodiment, non-limiting examples is as described below:
