Description

A kind of water-fast crack resistence wall putty
Technical field
The invention belongs to the development technique fields of putty for building, and in particular to a kind of water-fast crack resistence wall putty.
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 coating painting A kind of preceding essential product.Painting is imposed on priming paint or is directly applied and imposes on object, to remove height on coated article surface Uneven defect.It is formulated using a small amount of paint base, auxiliary agent, mass filler and suitable coloring pigment, pigment used is mainly Iron oxide red, carbon black, chrome yellow etc..Filler is mainly calcium bicarbonate, talcum powder etc..Part, which can be filled up, the working surface of recess, also may be used It is struck off in all surfaces, typically after prime coat parches, is applied over primer coat surface.It is required that adhesion is good, in baking process It does not crack.
Building coating has been widely used in the beautification and protection of building.But in practice, it has been found that even if the property of coating Can be excellent again, elasticity is good again, if the putty performance between wall and coating is bad, if itself cracking or dusting, then table The coating of layer cannot prevent this inherent cracking and dusting, therefore, often can see the blistering of coating, dusting, fall off, Phenomena such as infiltration, cracking, the aesthetics and quality of wall is seriously affected.Especially in moist basement, bathroom, such case It is more serious.These defects are caused by some are putty poor quality in fact.
