Abstract

The invention discloses a cement-based coating which is prepared from the following components in percentage by mass: 5-10% of deionized water, 0.1-0.15% of a preservative, 0.3% of an instant-type anti-settling agent, 1-1.5% of a dispersant, 0.1% of a wetting agent, 8-12% of heavy calcium carbonate, 15-20% of quartz powder, 5-10% of wollastonite, 45-50% of Portland cement, 0.3-0.5% of a surface modifying agent, 5-7% of superfine quartz powder, 0.3-0.5% of a rheology modifier, and 0.3-0.5% of carboxymethyl cellulose. The cement-based coating provided by the invention can effectively prevent the coating surface from damages caused by the external environment and surface cracking, is high in corrosion resistance capability and surface strength, is good in toughness and effect of water proof and mould proof, and is safe and environment-friendly.

Description

A kind of cement based coating

Technical field

A kind of cement based coating of the present invention has the feature of waterproof crack resistence.The invention belongs to the category of chemistry painting industry.

Background technology

Traditional cement based paint adhesion intensity is lower, is easy to easily ftracture between this concrete basic unit and waterproof layer, reduces the work-ing life of coating, and inventing a kind of cement based coating can effectively prevent coatingsurface from ftractureing, and waterproof effect is better.

Summary of the invention

Material name	Mass percent
		Deionized water	10
Sanitas	0.1
		Silica powder	20
Silicate cement	50
		Wollastonite	9
Carboxymethyl cellulose	0.3
		Surface-modifying agent	0.3
Rheology modifier	0.3

embodimenta kind of concrete component of cement based coating, the mass ratio of each component and concrete production technique are as follows:

Add the water of 10%, add the carboxymethyl cellulose of 0.3%, add sanitas, 0.3% surface-modifying agent, 0.3% rheology modifier, add the silicate cement of 50%, the wollastonite of 9%, the silica powder of 20% fully stirs, qualified rear packaging to be tested is dispatched from the factory.

Claims

1. a cement based coating, component and mass ratio are: the deionized water of 5%-10%; The sanitas of 0.1%-0.15%; The anti-settling agent of the Instant of 0.3%; The dispersion agent of 1%-1.5%; 0.1% wetting agent; 8%-12% water-ground limestone; 15%-20% silica powder; The wollastonite of 5%-10%; The silicate cement of 45%-50%; The surface-modifying agent of 0.3%-0.5%; The ultrafine quartz powder of 5%-7%; The rheology modifier of 0.3%-0.5%, 0.3%-0.5% carboxymethyl cellulose.

2. according to claim 1, a kind of cement based coating, it is characterized in that, the anti-settling agent that a kind of cement based coating is used is sodium base, in the coating taking water as carrier, dissolution rate is fast, more stable in coating, do not react with other material, anti-degraded, the ability of antisolvent precipitation is strong, effect is lasting, and not to environment, can reach international environmental requirement.
