Description
Technical field
The present invention relates to building material technical field, relate in particular to a kind of aldehydes removal except the preparation method of benzene radioprotective inner wall putty powder.
Background technology
Along with expanding economy, whether attractive in appearance people are more and more higher to indoor requirement, satisfy individual esthetic requirement by the decoration to indoor environment, and the caused environmental pollution of interior decoration is more and more serious.The formaldehyde that finishing material and coating discharge, volatile organic matter benzene and toluene, in addition, in interior decoration and the renovation process, also use a large amount of resol, the paint of floor furniture, wallpaper, the thinner of coating etc., this class material causes the airborne concentration of formaldehyde of family room can reach 0.05-2mg/m in case exposure just discharges formaldehyde
3Show according to health ministry, the Ministry of Construction and environmental administration's selective examination: the material that has at present toxic gas pollution accounts for 68%.It is reported, about 400 of the acute poisoning that China every year causes because of building coating, more than 1.5 ten thousand people poison, and dead about 350 people cause chronic poisoning to reach more than 100,000 person-times, and the crowd that China dies from room air pollution every year surpasses 110,000 people.In addition, the hertzian wave of the various different wave length frequencies that produce during the household electric appliance operations such as business automation equipment and microwave oven, receiving set, televisor, computer and mobile phone, these hertzian wave are full of the space, can penetrate the many materials that comprise human body, the radiation dose that people are exceeded standard.The serious harm that indoor environmental pollution brings is the challenge to HUMAN HEALTH and existence.
Putty is the supplementary material in the building coating coating process, and it is indispensable.Putty is under the coating, its major function is smooth metope and plays adhesive effect in metope basic unit and between filming, simultaneously can also prevent the metope peeling, be full of cracks, the phenomenon that comes off, only have good plasticity-and rheological, affine performance, compressive property, wear resisting property and good antiseep and heat preservation and insulation etc., guarantee construction quality.For example, Chinese invention patent application numbers 200610134425.7, the disadvantages such as common wall putty ftractures, comes off have been overcome, but for containing the organic solvents such as a large amount of formaldehyde, benzene in the colloid, do not overcome preferably, still exist the pungency peculiar smell large, the severe contamination room air produces the deficiencies such as greatly injury to human body.For example, Chinese invention patent publication number CN101215433A, it is natural that denomination of invention " multifunctional putty powder and method for making thereof " has been introduced a kind of raw material, prescription rationally, has the anti crack performance height, ultimate compression strength is high, water resistant abrasive proof, nonpoisonous and tasteless, the characteristics such as antibiotic, function is many, performance is strong, stable performance and easily construction, production technique is simple, as long as can be formulated through abundant mix and blend with various raw materials, and in process of production environment is had no adverse effects, its weak point is: only multifunctional putty powder itself has the anti crack performance height, ultimate compression strength is high, water resistant abrasive proof, nonpoisonous and tasteless, the characteristics of antibiotic grade, it can not effectively remove formaldehyde and electromagnetic radiation, indoor atmospheric pollution can not be removed again, mildew-resistant can not be played, the effect of anion releasing and anti-electromagnetic-radiation, and these atmospheric pollutions are very harmful to the mankind.
