Embodiment 1

[0028] Embodiment 1: The ingredient composition and weight of a kind of exterior wall color facing mortar with inorganic characteristics and excellent pan-alkaline resistance are as shown in the table:

[0029]

[0030] Note: The seasoning ratio of facing mortar is: water: component A: component B = 1:1:10

[0031] Mix the components of the above-mentioned facing mortar formula evenly, stir evenly with a mixer, and use it after aging for a period of time. It can be evenly coated on the cement substrate (similar to the surface of the outer wall) with a spatula to make figure 1 (ratio 1), figure 2 (ratio 2), image 3 (proportion 3) and Figure 4 (Proportion 4) shows the sample coating; respectively standard test conditions temperature (23 ± 2) ℃, relative humidity (50 ± 5)% under the condition of curing, and then according to the standard JC / T 1024-2007 wall finish The test method of mortar is to carry out pan-alkaline resistance test. Observed: ratio 1( figure 1 ) unde...

Abstract

The invention provides exterior wall facing mortar with an inorganic characteristic and excellent crystalline bloom resistant performance. The facing mortar comprises double components, wherein a component A is an acrylic emulsion, and a component B mainly comprises 5 to 15 percent of high alumina cement, 0 to 2 percent of gypsum, 70 to 75 percent of quartz sand, 0 to 12 percent of ultrafine calcium carbonate and 0.1 to 1 percent of additive. The exterior wall facing mortar provided by the invention has the advantages that through using the acrylic emulsion, a continuous film layer is formed after the mortar is solidified, so that the mortar is guaranteed to have high bonding strength and good anti-aging performance; the migration of salt can also be effectively prevented or reduced, so that crystalline bloom is controlled; and besides, the selection of the ratio of the high alumina cement to portland cement can also achieve a control effect on crystalline bloom. A template coating obtained through the mortar is detected according to a JC/T1024-2007 wall body facing mortar standard, and all performance indexes meet the requirements, so that the exterior wall facing mortar can be widely applied to the decoration of building wall bodies.

Description

technical field [0001] The present invention relates to a kind of mortar, especially relates to a kind of facing mortar which can decorate the exterior wall of buildings, and more particularly relates to a kind of mortar which has no efflorescence phenomenon during use, and has high strength, stain resistance and resistance Exterior wall finish mortar with inorganic characteristics such as aging. Background technique [0002] Finishing mortar is composed of inorganic cementitious materials (such as Portland cement and aluminate cement, etc.), mineral admixtures, additives and aggregates, and has good properties, such as air permeability, high impact resistance, Durability and stain resistance, etc., and the material properties are similar to the plastering mortar in the external thermal insulation system, and its elastic modulus, thermal expansion coefficient and other thermodynamic properties are similar to the plastering mortar, so it has better matching and compatibility ...
