Abstract

The invention discloses an anti-radiation function board and a preparation method of the anti-radiation function board. The anti-radiation function board comprises a first anti-radiation layer and a second anti-radiation layer, a first gridding cloth layer is further arranged between the first anti-radiation layer and the second anti-radiation layer, both the first anti-radiation layer and the second anti-radiation layer comprise sulphate aluminium cement, barite sand, a barite powder, barium sulfate, quartz sand and an impurity, and the first gridding cloth layer is a fiberglass mesh. Compared with the prior art, the fiberglass mesh is taken as a toughening material, so that the impact resistance and the bending strength of the anti-radiation function board are improved; a prefabricated panel is rapidly formed by means of hot press molding; the characteristic of high density of the panel is realized under high pressure; besides, the panel achieves a decorative effect by means of a hotpress molding process, and the forming time is obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a radiation-proof functional board and a preparation method thereof. Background technique [0002] With the development of modern society, an invisible and intangible source of pollution has attracted increasing attention from all walks of life, which is electromagnetic radiation known as the "invisible killer". For the human body, a good conductor, electromagnetic waves will inevitably pose a certain degree of harm. Generally speaking, radar systems, television and radio transmission systems, radio frequency and microwaves, medical equipment, communication transmission stations and ultra-high voltage transmission lines, and most household appliances can generate electromagnetic waves of various forms, different frequencies, and different intensities. source of radiation. The anti-radiation plates provided in the prior art are mostly lead plates, which are single in var...
