Abstract

The invention discloses a cement mortar. The cement mortar comprises, by mass, 50 to 80% of an electromagnetic wave shielding material, 15 to 45% of cement, 1 to 4% of a filling material, 0 to 0.5% of fiber and 0.1 to 2% of an organic additive. The cement mortar has an electromagnetic wave shielding function and exerts high shielding effect on electromagnetic waves with a frequency of 10 KHz to 18 GHz. The cement mortar provided by the invention has building performance parameters similar to the building performance parameters of common plastering mortar, can be applied to manufacturing of floated coats of interior and exterior walls of a variety of buildings and be smeared by using common construction means, and is convenient to apply and reliable in performance.

Description

technical field [0001] The invention relates to the technical field of cement mortar, in particular to a cement mortar with electromagnetic wave shielding function. Background technique [0002] Due to the rapid development of science and technology, a large number of electronic devices are used in daily life, but what follows is complex electromagnetic wave environmental pollution. Constructing a functional layer with electromagnetic wave shielding or absorption on the building wall is a common method of shielding electromagnetic waves. In the existing solutions, the shielding effect of the shielding material is poor, and the content is low, so the shielding effect on electromagnetic waves is poor. In addition, the existing shielding structure is relatively complicated, the shielding band is generally limited to high frequencies, and the strength is low. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencie...
