Problems solved by technology

Filled anti-radiation materials contain toxic and harmful substances such as lead and its compounds, volatile organic compounds, and free formaldehyde that are restricted by national standards. In addition, filled anti-radiation materials are filled in the middle of the wall, destroying the complete structure of the wall. Potential safety hazards, such as cracks or holes in the filling during construction and use, can not be found by people, which is a potential hazard; the production process of composite protective panels is complicated, and the seams between panels are not easy to deal with; they are generally not used in civil buildings

Abstract

The invention discloses a radiation protection paper surface plasterboard and a method for manufacturing the same. The formula of the radiation protection paper surface plasterboard is as follows: radiation protection materials including 5 to 40 percent of barium sulphate, 10 to 20 percent of calcium carbonate, 5 to 10 percent of quartz powder and other additives are added in the formula of the plasterboard; the plasterboard is mainly applied to the non bearing wall system and the man-carrying or non man-carrying suspended ceiling system and can effectively avoid radiations such as X rays and Gmman rays etc., and has the advantages of non-toxicity, odorlessness, low price, convenient construction and good protective property; so that the plasterboard can be widely applied to the architectural decoration.

Description

technical field [0001] The invention relates to a radiation-proof paper-faced gypsum board and a preparation method thereof, a building decoration material capable of blocking X and Y rays, and is mainly used in non-load-bearing wall systems and ceiling systems. Background technique [0002] With the wide application of radiation in the fields of medical and health, national defense and military industry, scientific research, industry, agriculture, etc., especially X and Y rays have become the most widely used ionizing radiation; radiation technology has brought huge economic benefits to society, but another On the one hand, due to its high energy and strong penetrating power, it has different degrees of damage to human physiological functions; for example, people who have been exposed to X-rays for a long time will have skin burns, hair loss, cloudy eye lenses, leukopenia, and sexual dysfunction. Symptoms; severe cases lead to gene defects and induce cancer; in order to blo...
