Abstract
The invention discloses a plastering mortar used for heat preservation for an outer wall. The plastering mortar includes the following components, by weight: 1-2 parts of glazed hollow beads, 5-10 parts of sepiolite, 20-25 parts of expanded perlite, 80-100 parts of cement, 1-2 parts of steel fibers, 20-30 parts of steel slag sand and 1-3 parts of re-dispersible latex powder. The plastering mortar has damp-proof, heat-preservative and anti-cracking effects.
Description
Technical field
The present invention relates to a kind of plastering mortar, be specifically related to a kind of plastering mortar for exterior-wall heat insulation.
Background technology
All mortars spreading upon buildings or building slab surface, are referred to as plastering mortar.According to the difference of plastering mortar function, plastering mortar can be divided into common plastering mortar, decoration mortar and there is the plastering mortar (as waterproof mortar, adiabatic mortar, sound-absorbing mortar and acid resisting mortar etc.) of some specific function.Plastering mortar is required to have good workability, easily smears uniformly smooth thin layer, constructability.Also should have higher cohesive force, screed should be able to cohere firmly with bottom surface, long-term unlikely cracking or come off.Be in wet environment or be subject to External Force Acting position (as ground and dado etc.), also should have higher water tolerance and intensity.
Summary of the invention
The object of the invention is the plastering mortar in order to provide a kind of protection against the tide, insulation, cracking resistance.
In order to achieve the above object; the invention provides a kind of plastering mortar for exterior-wall heat insulation; comprise the component of following weight proportion: glass bead 1-2 part; sepiolite 5-10 part; pearlstone 20-25 part, cement 80-100 part, steel fiber 1-2 part; Steel-slag Sand 20-30 part, redispersable latex powder 1-3 part.
Wherein, Steel-slag Sand answers ageing more than 1 year, and free calcium oxide content is less than 3%, and metal Ferrum content is less than 1%, obtained after broken, screening, oven dry, magnetic separation; The size of described Steel-slag Sand is 0.6mm-1.2mm.
Cement adopts ordinary Portland cement.
Length of steel fiber is 1-3mm.
The weight proportion of plastering mortar preferred ingredient of the present invention is: glass bead 2 parts, sepiolite 8 parts, pearlstone 20 parts, cement 100 parts, steel fiber 2 parts, Steel-slag Sand 20 parts, redispersable latex powder 1 part.
The present invention has the following advantages compared to existing technology: the present invention utilizes sepiolite and pearlstone to the absorption property of water vapor in air; adjusting air humidity; moistureproof; simultaneously with the use of glass bead; regulate the expansion bubbling because sepiolite and the excessive adsorb water vapor of pearlstone cause and cracking on the one hand; ensure the planarization of wiping one's face, jointly play heat insulation effect with pearlstone on the other hand.The present invention utilizes steel fiber and Steel-slag Sand to improve the resistance to cleavage of mortar simultaneously, and the plastering mortar tensile bond strength prepared is greater than 0.2MPa, and thermal conductivity is less than 1.2W/ (m.k), and leakless, efflorescence, peels off.
