Hardened cement among the present invention (comprising the gentle hardened cement of water hardening gelling material) has coating curing function and attachment function, and its principle of solidification is as follows:
1, building material product of the present invention (is promptly smeared and is formed coating) after Jia Shui stirs construction, large quantity of moisture in the coating outwards evaporates or (this basic unit refers to be coated with basic unit by basic unit, as metope etc.) absorb, the hole net that coating is formed communicate with each other in a large number, owing to stay surface tension in intrapore free water, produce capillary pressure, make coating particle more closely obtain intensity.
2, coating camber dispersive colloidal particle is separated by interparticle diffusion water layer, and when moisture reduces gradually, during diffusion water layer attenuate, colloidal particle bonding mutually under the effect of molecular force is condensed into reticulated structure and obtains intensity.
3, coating absorbing carbon dioxide gas from air solidifies and acquisition intensity.
4, in the coating because constantly the carrying out of hydration reaction, liquid phase constantly reduces, solid phase constantly increases and makes coating lose plasticity-gradually and obtain intensity.
Rewetting rubber powder among the present invention (comprising latex powder, polyvinyl alcohol powder and modified natural plant gum powder), these powder can be dissolved into colloidal fast and be produced cohesive force in cold water, under the condition of alkalescence, produce crosslinking reaction with gelling material, formed water-fast resin structure after the coating drying.Simultaneously, this rewetting rubber powder has improved snappiness, water-repellancy, sticking power and the application property of coating greatly in formula system of the present invention.
Mierocrystalline cellulose among the present invention, auxiliary agents such as dispersion agent, defoamer and mould inhibitor, and cement additive, anti-crack fiber and pigment powder be raw material, is used for improving the color of structural, water-repellancy, mildew resistance, splitting resistance and the coating of thickening water-retentivity, application property, the coating of system respectively.
Building material product of the present invention is Powdered, and environment-protecting asepsis directly adds and can use after water stirs.Have that cohesive force is strong, snappiness reaches the smooth characteristics of construction well, coating is water-fast (waterproof), fire-retardant, alkali resistant, anti-mildew and ageing-resistant, it can reach national JG/T3049-1998 and JG/T157-2004 standard index fully.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
