Problems solved by technology

Because large-scale artificial landscaping is different from ordinary buildings, the current construction technology can no longer meet the needs of the construction period. At the same time, the existing mortar also has poor corrosion protection of steel structure, insufficient pumping, insufficient bonding strength, Insufficient crack resistance and other problems

Abstract

The invention provides a polymer spraying mortar and its preparation method. The polymer spraying mortar contains a premixed powder and water, wherein water accounts for 14-17% of the premixed powder. The premixed powder comprises the following ingredients, by weight, 15-25% of cement, 30-55% of coarse aggregate, 0.1-2% of rubber powder, 5-10% of fine aggregate, 1-5% of an active lightweight object and 1-3% of a premixed additive, wherein the premixed additive contains a corrosion inhibitor which enables the polymer spraying mortar to delay steel corrosion time; and by adding components such as flaky mica, powdered steatile and the like into the active lightweight object, the polymer spraying mortar has good shielding property and thixotropy.

Description

【Technical Field】 [0001] The invention relates to the field of artificial landscaping materials, in particular to a polymer spray mortar and a preparation method thereof. 【Background technique】 [0002] At present, most artificial landscaping and buildings in China are still carried out by artificial plastering. However, the artificial plastering construction method is often due to insufficient or uneven bonding force between the mortar and the wall, which often results in hollow or hollow walls. Falling off and other phenomena have caused great problems in the construction quality; at the same time, due to the great problems of labor, the construction method of plastering requires a lot of manpower input, resulting in an increase in engineering costs. Therefore, some people began to introduce foreign machinery in the construction field. Compared with manual plastering, mechanical spraying has the advantages of faster speed, better stability and reduced labor. However, due to var...
