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.
