Embodiment 1

[0012] Component A is 30 kg of 250 mesh heavy calcium carbonate, 5 kg of 500 mesh talc powder, 35 kg of 100 mesh quartz sand, 28.48 kg of Portland 42.5 cement, 1 kg of redispersible latex powder, 0.5 kg of hydroxyethyl methyl Base cellulose ether, 0.02 kilogram of modified starch ether;

[0013] Component B is 12 kg of acrylic emulsion;

[0014] Combining components A and B into a set makes a two-component exterior wall putty.

Embodiment 2

[0016] Component A is 31.7 kg of 500 mesh heavy calcium carbonate, 15 kg of 250 mesh talcum powder, 25 kg of 150 mesh quartz sand, 25 kg of Portland 42.5 cement, 3 kg of redispersible latex powder, 0.2 kg of hydroxyethyl methyl Cellulose ether, 0.1 kilogram of modified starch ether;

[0017] Component B is 5 kg of acrylic emulsion;

[0018] Combining components A and B into a set makes a two-component exterior wall putty.

[0019] The usage method of the present invention:

[0020] 1. Preparation before use:

[0021] Spray water to remove all loose, easy-to-fall, and stained materials, and construction can only be carried out after the surface layer is dry; other tools such as hammers can also be used to hammer the loose materials into pieces and remove them, so as to provide a clean place for putty construction. surface.

[0022] 2. Mixing procedure:

[0023] Pour 20-30kg of water into 5-12kg of component B, then add 100kg of component A and keep stirring to prevent comp...

Abstract

The invention relates to external wall putty, which comprises two components of A and B according to following weight percentage: component A comprises 30-40 percent of heavy calcium carbonate, 5-15 percent of talcum powder, 25-35 percent of quartz sand, 25-30 percent of Portland, 42.5 of cement, 1-3 percent of subdividable latex powder, 0.2-0.5 percent of ethoxyl methyl cellulose ether, and 0.02-0.1 percent of modified starch ether; component B is 5-12 percent of crylic acid latex; assorting ratio of component A and B is 100:5-12. The external wall putty has the advantages that cracks and pores can be padded; after hard drying, the product is characterized by strong adhesion force, good water resistance and corrosion resistance, smooth surface layer, crack control, and good impact resistance; after tested, 0.8 MPa is reached under a standard state in terms of bond strength; after five times of freeze-thaw cycles, bond strength of the putty reaches 1.03 MPa; the putty can be extensively applied to alteration and face lifting of external walls, which provides smooth underside base material for applying dope.

Description

technical field [0001] The invention belongs to the field of building materials and relates to a two-component exterior wall putty. Background technique [0002] At present, there are many kinds of putty for exterior walls, which are mainly used for cement walls and concrete walls, with different strengths. When the exterior wall putty is used to renovate some tile walls and mosaic walls, the putty has defects such as weak adhesion and poor water resistance. Contents of the invention [0003] The purpose of the present invention is to provide a kind of putty with strong adhesion, excellent water resistance and suitable for external walls. [0004] The present invention can be realized in the following manner: the exterior wall putty is composed of two components A and B calculated according to the following weight percentages: component A is 30-40% ground calcium carbonate, 5-15% talcum powder, 25% ~35% quartz sand, 25~30% Portland 42.5 cement, 1~3% redispersible latex p...
