Carry out direct tensile test.The result shows that：Mortar specimen uniaxial tensile strength average value is 3.9MPa, and ultimate tensile strength can reach
1.4%, bearing capacity is held essentially constant test specimen cracking later, has good tensile toughness, occurs in destructive process less than 10
Crack.
It is required according to the standard of the mortar of JC/T1024-2007, outdoor test is carried out 6 months to above-mentioned crack resist at mortar, nothing
Thus it is clear that the accumulation of salt in the surface soil, without picking, it can be seen that, the addition of modified zeolite and methacrylate, which has alkali burnout resistance and adhesion strength, to be changed
It is kind.
Reference examples are set up, preparation method is removed with specific embodiment described in embodiment 1 and do not add in tetrapropylene benzene sulphur
Outside sour sodium and coconut oil diethanol amine, remaining step and reagent all same, according to JC/T1024-2007 wall facing mortars
Standard requirement is tested, and the water absorption situation obtained by 1 gained mortar of embodiment and reference examples in mortar 30min is respectively 0.4g
And the water absorption situation of 1.9g, 240min are respectively 0.6g, 2.5g, are met the technical requirements；According to GB/T 13891-
2008《Test methods of specular gloss for decorative building materials》Standard requirement tested, 1 gained mortar of embodiment and control
60 o glossiness of example gained mortar are respectively 14.5,7.2.
Toughness is preferable when crack resist at mortar compression, tension knowable to above-mentioned experiment, is not susceptible to brittle break, intensity
Well, effect of prestressed is good, ductility is good, alkalescence is weak, can effectively protect vacuum heat-insulating plate and mitigate the corrosion journey to glass fiber mesh
Degree.Pass through the addition of dispersant, surfactant tetrapropylene benzene sodium sulfonate and coconut oil diethanol amine so that be infiltrated on boiling
Oleic acid inside stone gap is dispersed in during agitating and heating in mortar, is effectively improved the surface gloss of mortar,
The aesthetic measure and decoration function of mortar are improved, and due to employing tetrapropylene benzene sulfonic acid in the mortar of the utility model
Sodium and coconut oil diethanol amine can effectively uniformly disperse a small amount of oleic acid that zeolite pores adsorb for oil droplet little particle so that nothing
Oleic acid or oleate need to be added in, and only needs to reach in a manner that oleic acid infiltrates and adds in what a large amount of oleic acid can be only achieved
Brightness, glossiness and water resistance reduce the dosage of oleic acid or oleate, reduce cost；Acetic acid inside zeolite pores
It is released in whipping process in mortar, effectively improves the basicity of mortar.
