Embodiment 1

[0036] Put 40 parts by weight of petroleum asphalt with a penetration of 120 in the reaction tank, add 5 parts by weight of plasticizer naphthenic oil, and then add 10 parts by weight of polymer modifier linear SBS (styrene-butadiene-styrene , styrene-butadiene-styrene block thermoplastic elastomer) and 10 parts by weight of SBR styrene-butadiene rubber, after mixing evenly, the temperature of the material was raised to 200°C, stirred and sheared for 2 hours until the polymeric agent was completely dispersed in In the asphalt, the temperature of the material is lowered to 185°C, and 10 parts by weight of boron ore, the basic material of radon radiation, barite, and 10 parts of barite, the basic material of radon radiation, are added. Iron ore powder and 5 parts by weight of rutile-type titanium dioxide were stirred and mixed for 1 hour to a uniform state, and a radon-proof radiation-modified asphalt compound was prepared. Then, the modified asphalt is dip-coated on the polyest...

Embodiment 2

[0039]Put 55 parts by weight of petroleum asphalt with a penetration of 70 in the reaction tank, add 15 parts by weight of plasticizer aromatic oil, and then add 5 parts of polymer modifier linear SBS (styrene-butadiene-styrene , styrene-butadiene-styrene block thermoplastic elastomer), after mixing evenly, raise the temperature of the material to 195°C, stir and shear and grind for 1.5h until the polymer modifier SBS is completely dispersed in the asphalt, and the material The temperature drops to 180°C, add 15 parts by weight of radon-proof radiation basic material graphite, 5 parts by weight of radon-proof radiation basic material clay and 5 weight parts of radon-proof radiation basic material magnetite powder, stir and mix 1h to a uniform state, the anti-radon radiation modified asphalt compound is prepared. Then, the modified asphalt is scraped on the PET polymer carcass to prepare the finished product through processes such as thickness control and shaping, film coating ...

Embodiment 3

[0042] 20 parts by weight of natural asphalt with a penetration of 120 is placed in the reaction tank, 20 parts by weight of plasticizer naphthenic oil is added, and 5 parts by weight of polymer modifier SBS (styrene-butadiene-styrene, benzene Ethylene-butadiene-styrene block thermoplastic elastomer), 5 parts by weight of IIR butyl rubber, 5 parts of BR butadiene rubber and 10 parts of hot melt adhesive, after mixing evenly, raise the temperature of the material to 180 °C , stirring, shearing, and grinding for 2 hours until the modified polymeric agent is completely dispersed in the asphalt, the temperature of the material is lowered to 180 ° C, and 5 parts by weight of diatomite and 10 parts by weight of anti-radon radiation element material are added. The volcanic rock powder, 10 parts by weight of zinc ore powder, the basic element material for preventing radon radiation, and 10 parts of mica, the basic material for preventing radon radiation, were stirred and mixed for 1.5 ...

Abstract

The invention relates to radon-resisting waterproofing roll roofing. The radon-resisting waterproofing roll roofing is prepared by carrying out roll coating / blade coating / dip coating on a radon radiation resisting modified asphalt compound on a matrix / an isolating membrane, controlling the thickness and setting, laminating, rolling and the like. The radon radiation resisting modified asphalt compound is prepared from 20 to 90 percent of matrix asphalt, 0.1 to 30 percent of polymer modifier, 1 to 50 percent of radon radiation resisting elementary material and 0.1 to 20 percent of additive. The invention also provides a preparation method of the radon-resisting waterproofing roll roofing. The radon-resisting waterproofing roll roofing disclosed by the invention has excellent water-proof property, and the functions of radon radiation resistance, air purification and the like.

Description

technical field [0001] The invention relates to the technical field of building materials and environment-friendly building materials, in particular to a radon-proof waterproof coiled material and a preparation method thereof. Background technique [0002] Radon is a colorless, odorless, radioactive inert gas that is the decay product of radioactive elements such as uranium, radium, and thorium. In 1988, the International Agency for Research on Cancer listed radon as a human carcinogen, and the World Health Organization (WHO) announced that radon is one of the 19 important human carcinogens, and it is also the second largest cause of human lung cancer after cigarettes. [0003] Radon is distributed throughout the earth's crust. In the indoor environment where humans work and live, radon mainly comes from the underlying soil of buildings, indoor building decoration materials, outdoor atmosphere, domestic water and household fuel. The average concentration of radon in the hou...
