Description

Moisture-proof mould decorative mortar of one kind and preparation method thereof
Technical field
The present invention relates to construction material and its technical field of construction, more particularly, to a kind of moisture-proof mould decorative mortar and its system Preparation Method.
Background technique
Decorative mortar is building masonry wall surface construction indispensable material.Construction wall is generally wanted after the completion of masonry Carry out sand finish construction, so that each masonry block (such as brick) is connected and composed an entirety, increase intensity, cram masonry block it Between gap, while levelling masonry panel surface in order to decorate (wallpaper, tiling scrape great Bai, swabbing) construction.Mesh Before, common decorative mortar adds water mixing to be made by cement, sand mostly, according further to needing to add some additives such as 107 glue, antifreeze, water-reducing agent, swelling agent etc. substantially can satisfy the plastering requirement of interior ground routine building surface of wall. But in coastal area, especially Northern Coastal Provinces, due to special climatic factor, difference variation is big, wind is big and it is changeable, There was dampness in the air (potassium, sodium, chlorine ion concentration are high in sea wind and seawater), after the construction of conventional decorative mortar, the guarantor of surface of wall Water poor air permeability, metope is easy to crack, easy peeling, and wall-body energy saving is caused the mould phenomenon of tide occur, not only pollutes environment, the harm person Health reduces strength of wall body, and influences indoor beauty, brings great worry to people's life.
Summary of the invention
To overcome prior art defect, the technical problem to be solved by the present invention is to provide a kind of moisture-proof mould decorative mortar and its systems Preparation Method, the mortar workability, water conservation good permeability, metope is not easy to crack, is not easy to peel off, and can effectively overcome Northern Coastal Provinces Special climatic factor (potassium, sodium, chlorine ion concentration in humid air are high, sea wind is big, the temperature difference is big) influences, and reduces construction wall The probability that goes mouldy easily occurs for inner wall surface.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of moisture-proof mould decorative mortar, which is characterized in that the raw material components including following parts by weight: cement 100-120, build Build sand 550-660, lime paste 50-60, flyash 25-30, diatomite 50-60,107 glue 5-7, additive 17.5-27.
The cement is preferably portland slag cement, ordinary portland cement or Portland fly ash cement, intensity etc. Grade is 32.5.
The building sand average grain diameter is 0.35-4.5mm, and clay content is less than 1.0%.
The additive is to be made of raw material from the following weight to be made: ST2000 type starch ether 1-3, EP-13 epoxy resin 1.5-2.5, methyl cellulose ether 2-3, polycarboxylic acids pulvis water-reducing agent 3-4, alkyl silicate waterproofing agent of organosilicon 3-4, C12H25N (EO)7(PO)5H organosilicon reinforcing agent 2.5-3.5, styrene 1-1.5, calcium silicates 2.5-3.5, sodium nitrite and carbonate mixing Type antifreezing agent 1-2.
A kind of preparation method of moisture-proof mould decorative mortar, which comprises the following steps:
1) by building sand it is dry to moisture content 0.5% hereinafter, being sieved and rejecting clay, grass roots, leaf and other organic Object harmful substance, the particle greater than 4.5mm are sent into crusher, and blender is sent into remaining weighing；
2) it is admitted to building sand of the crusher greater than 4.5mm to be crushed again, repeats step 1)；
3) diatomite is put into baking oven and carries out drying and processing, oven temperature is more than or equal to 300 DEG C；
4) diatomite after drying and processing being ground, is sieved, the particle greater than 200 mesh continues to re-grind, Blender is sent into remaining weighing；
5) it drenches lime paste processed: aperture being arranged in sedimentation basin no more than 3mmx3mm square hole screen, is drenched with lump lime System, room temperature lower curing time are 15-30 days；
6) lime paste, flyash, 107 glue that cement, leaching make are weighed respectively and is sent into blender, be stirred 1.5- 2.5min；
7) by ST2000 type starch ether, EP-13 epoxy resin, methyl cellulose ether, polycarboxylic acids pulvis water-reducing agent, alkyl silicon Hydrochlorate waterproofing agent of organosilicon, C12H25N(EO)7(PO)5H organosilicon reinforcing agent, styrene, calcium silicates, sodium nitrite and carbonate Mixed type antifreezing agent, which weighs to premix respectively, is made additive, is sent into blender and is stirred 10-15min up to dry-mixed mortar；
8) it at the construction field (site), adds water and stirs and is mixed up to decorative mortar in 15-20% ratio, can be used for construction wall plastering Construction.
Compared with prior art, the beneficial effects of the present invention are:
1) have the characteristics that good workability, water conservation gas permeability and crack resistance according to decorative mortar prepared by the present invention, (potassium, sodium, chlorine ion concentration height, the sea wind in humid air are big, warm for the climatic factor that can effectively overcome Northern Coastal Provinces special It is poor big) it influences, it reduces internal wall surface of building wall body and the probability that goes mouldy easily occurs；
2) poisonous and harmful substance is free of according to the diatomite that decorative mortar prepared by the present invention contains, it is wear-resisting to be not pulverized easily, Air can be purified, it is environmentally protective；
3) preparation method is simple, and cost is relatively low, easy to spread.
