3O
2 -Negative ion can also killing pathogenic bacteria, purify air.Generally speaking, the people needs about 13,000,000,000 negative ions every day, and our room, office, environment such as public place of entertainment can only provide hundred million of about 1-20.Huge contrast between this supply and demand often causes pneumonia, the respiratory disease of trachitis easily.The air-conditioning system of central heating and air-cooling system, negative ion often is purged.Existing inner wall decoration mortar does not discharge the function of negative ion.Existing inner wall decoration mortar adopts quartz sand as aggregate mostly, it must just can meet service requirements through a series of processing treatment, comprises screening, oven dry, requires the expenditure of energy when broken, and can produce a large amount of byproduct contaminate environment, processing cost is higher.
Summary of the invention
The invention provides a kind of drift-sand that adopts as aggregate, match volume are outstanding, resistance to cleavage is good and have the ecological, environmental protective inner wall of building decoration mortar of negative ion-releasing function.Simultaneously, the present invention also provides the constructional method of this mortar.
For solving the problems of the technologies described above, the invention provides a kind of inner wall decoration mortar, it is characterized in that, mix by the component of following parts by weight:
Ordinary Portland cement 8-15
White lime 3-4
Light-weight aggregate 3-5
Negative-ion auxiliary agent 4-6
Heavy aggregate 70-80
Composite assistant 1.0;
Described light-weight aggregate is that fineness is lower than the inorganic vitreous hollow microporous material of 100 purposes;
Described heavy aggregate is a drift-sand.
Described negative-ion auxiliary agent be tourmalinite.
Described tourmalinite fineness is more than 180 orders.
The fineness of described inorganic vitreous hollow microporous material is the 80-100 order.
In the described drift-sand, fineness be 50-70 purpose drift-sand weight percentage greater than 90%, the fineness of all the other drift-sands is greater than 100 orders.
Be made up of water-holding agent, air entrapment agent, redispersable latex powder and lignocellulose in the described C type composite assistant, the parts by weight proportioning is a wood fiber element 0.15: water-holding agent 0.2: air entrapment agent 0.3: redispersable latex powder 0.35.
The fineness of described white lime is more than 300 orders; The fineness of described ordinary Portland cement is more than 185 orders.
Described ordinary Portland cement is a white cement.
Described inner wall decoration mortar, preferably the component by following parts by weight mixes:
