A kind of exterior wall spraying putty and preparation method thereof

Abstract

The invention discloses putty for external wall spraying and a preparation method of putty. The putty contains the following raw materials in parts by weight: 260-320 parts of ash concrete, 250-300 parts of coarse whiting, 320-370 parts of snowflake white, 100-150 parts of talcum powder, 1-3 parts of lignocelluloses, 3-6 parts of cellulose ether, 6-10 parts of rubber powder, 2-4 parts of a water reducer, 2-4 parts of attapulgite and 2-4 parts of starch ether. The putty is prepared from multiple materials such as the rubber powder, the cement, a filler and an additive through compounding, is high in bonding strength and good flexibility and thixotropy, can adequately play roles of external wall leveling and decoration, has good thixotropy and flow resistance and does not flow, and the spraying construction can be realized.

Description

technical field

[0001] The invention belongs to the technical field of building materials, and relates to rough wall leveling materials, specifically inventing an exterior wall putty, which is combined with a spraying machine for mechanized construction, improves construction efficiency, reduces labor costs, and shortens the engineering period. Background technique

[0002] The traditional batch scraping putty has low construction efficiency, high labor cost and long construction period. To this end, a high-performance exterior wall putty is developed, combined with a spraying machine for mechanized construction, which reduces project cost and improves construction efficiency.

[0003] In the existing invention patent application CN 103342506 A, the cost of the formula system is too high, the sandability is poor, the fine powder is too much, and it is easy to crack; it brings certain difficulties to the mechanized construction of putty spraying on the exterior wall.

Examples

Embodiment 1

[0028] The formula of the external wall spray putty is calculated by mass: 265 parts of 325# gray cement, 290 parts of 325 mesh heavy calcium, 310 parts of 80-120 mesh snowflake white, 110 parts of 400 mesh talcum powder, 1 part of lignocellulose, fiber 6 parts of plain ether, 8 parts of rubber powder, 4 parts of F10 superplasticizer, 2 parts of 601 attapulgite and 4 parts of FP6 starch ether.

Embodiment 2

[0030] The formula of this external wall spraying putty is calculated by mass: 280 parts of gray cement, 279 parts of heavy calcium, 40 parts of 40-80 mesh snowflake white sand, 279 parts of 80-120 mesh snowflake white sand, 100 parts of talcum powder, 2 parts of lignocellulose 4 parts, 4 parts of cellulose ether, 6 parts of rubber powder, 4 parts of water reducer, 4 parts of attapulgite and 2 parts of starch ether.

Embodiment 3

[0032] The formula of the external wall spray putty is calculated by mass: 310 parts of 325# gray cement, 250 parts of 325 mesh heavy calcium, 50 parts of 40-80 mesh snowflake white sand, 260 parts of 80-120 mesh snowflake white sand, 106 parts of 400 mesh talcum powder 3 parts, 3 parts of lignocellulose, 3 parts of cellulose ether, 10 parts of rubber powder, 2 parts of water reducing agent, 3 parts of attapulgite and 3 parts of starch ether.

[0033] When the above-mentioned exterior wall spray putty is prepared, gray cement, heavy calcium and talcum powder are put into a mixer in turn for mixing, and then lignocellulose, cellulose ether, rubber powder, water reducer, attapulgite and starch ether are put in and mixed in turn, Finally, add snowflake white and mix evenly to obtain putty for exterior wall spraying.
