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

A kind of radiation protection gypsum lath and preparation method thereof

Technical field

The present invention relates to a kind of radiation protection gypsum lath and preparation method thereof, a kind of building and ornament materials that stop X, gamma ray are mainly used in non-load bearing wall system and ceiling system.

Background technology

Along with radioactive rays at field widespread use, particularly X, gamma rays such as health care, defence and military, scientific research, industry, agriculturals, become people to use maximum ionizing rayss; Radiotechnology has been brought huge economic benefit to society, and but then, because its energy height, penetration power is strong, and human physiological functions is had in various degree detrimental effect; Symptoms such as skin burn, trichomadesis, lens opacity of eye, leukopenia, sexual hypofunction can appear in the people as long-term contact x-ray bombardment; Weight person causes genetic flaw and brings out cancer; For stopping the radiation of gamma ray, early stage people adopt the stereotype protection, and well-known, plumbous matter is soft and poisonous, long easy creep of time, and construction of prevention work program complexity costs an arm and a leg; X, gamma ray all have stronger penetration power, and it can pass general thickness building masonry wall, ceiling, though yield of radiation weakens to some extent, but still HUMAN HEALTH is constituted certain threat, block ray for making body of wall, usually with its thickening, this method is not only wasted material of construction, also useful spaces that accounted for more;

At present, the x ray is adopted stereotype, composite protective plate more both at home and abroad.The filling anti-radiation material all contains hazardous and noxious substances lead and compound, volatile organic compounds and the free formaldehyde of national standard restriction, filling anti-radiation material in addition, be to be filled in the middle of the body of wall, destroyed the body of wall complete structure, there is building safety hidden danger, in construction and use, crack or hole occur, can't be it is found that to have potential hazard as charges; Composite protective board production technology complexity, the seam thread cast-off also is difficult for handling between plate; They generally can't use at covil construction.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, seek that production technique is simple, easy construction, the occupation of land space is little, raw material sources abundant, cheap and not leaded and hazardous and noxious substances such as compound, volatility toxic pollutant, stop X, gamma ray anti-radiation building material effective, that can be widely used in covil construction.

Technical scheme of the present invention is:

A kind of radiation protection gypsum lath its preparation method comprises that step is as follows:

Step 1, to plasterboard batching, mainly form by terra alba, whipping agent, starch, mask paper, its proportioning for its weight percent is: barium sulfate: 5-40%, lime carbonate: 10-20%, quartz: 5-10%, red iron oxide: 1-5%, yellow soda ash: 1-3%, white glue with vinyl: 2-5%;

Step 2, by above-mentioned weight percent batching; Technology adds water and mixes routinely;

Step 3, moulding;

Step 4, oven dry;

Step 5, finished product.

A kind of radiation protection gypsum lath has added radiation resistance materials such as barium sulfate, lime carbonate, quartz and other additives in the prescription of Thistle board, its weight percent is:

Barium sulfate: 5-40%, lime carbonate: 10-20%, quartz: 5-10%, red iron oxide: 1-5%, yellow soda ash: 1-3%, white glue with vinyl: 2-5%.

The present invention goes for the use range of all Thistle boards, can make non-load bearing wall system and ceiling system, has radioprotective effect preferably.Be mainly used in non-load bearing wall system and manned or non-manned ceiling system, can stop the radiation of X, gamma ray etc. effectively, have that nontoxic, odorlessness, price are low, an easy construction, advantage that barrier propterty is good, can be in building decoration and fitment wide popularization and application.

The invention has the beneficial effects as follows:

1, the present invention has good shielding property.

2, poisonous, nuisance such as not leaded and compound etc. in the component can not pollute the working space, and waste material can not cause secondary pollution.

3, easy construction, good with the protection body adhesiveproperties, do not chap, do not come off, no matter teacher's new building still is original radiation working space all can be adopted.

4, the radiation shielding coating raw material sources are abundant, and cheap, production technique is simple and reliable, and it is low to consume energy, and product performance are stable, transport easily and store.

5, can adopt different ratios according to different occasions.
