A kind of preparation method of high-intensity wall putty
Technical field
The invention belongs to the development technique field of putty for building, and in particular to a kind of preparation side of high-intensity wall putty
Method.
Background technology
Putty (fillering) is a kind of decoration type material of smooth surface of wall, is a kind of thick slurry coating material, is that coating paints
A kind of preceding essential product.Painting is imposed on priming paint or directly applied and imposes on object, to remove height on coated article surface
The defects of uneven.It is formulated using a small amount of paint base, auxiliary agent, mass filler and appropriate coloring pigment, pigment used is mainly
Iron oxide red, carbon black, chrome yellow etc..Filler is mainly calcium bicarbonate, talcum powder etc..The local working surface for having depression can be filled up, also may be used
Struck off in all surfaces, typically after prime coat parches, be applied over primer coat surface.It is required that tack is good, in baking process
Do not crack.
The filler of putty mainly has silica flour, quartz sand, dry powder etc., and base-material is typically all cement, and cement is with cement in putty
The effect of the cement of mortar or cement concrete is the same, all plays a part of cohesive aggregate, for cement as base-material, coagulability is good, close
Degree is big, but its constructional difficulties, is not easy to renovate, and preceding processing cost is higher, once cracked, reparation difficulty is big, mechanical property
Decline fast.
The content of the invention
