High-self-adhesive waterproof roll material of SBS (Styrene-Butadiene-Styrene) modified asphalt and production process thereof
InactiveCN101967868ARoof covering using flexible materialsBuilding insulationsPolymer scienceUltimate tensile strength
The invention relates to a high-self-adhesive waterproof roll material of SBS (Styrene-Butadiene-Styrene) modified asphalt and a production process thereof. The waterproof roll material comprises tire fabric, an oil-lubricated coating layer, a separating layer and a filming layer, wherein the oil-lubricated coating layer is prepared from the following materials in percentage by weight: 35-40 percent of alkyl asphalt, 10-13 percent of SBS binder, 3-5 percent of naphthenic oil, 5-13 percent of coumarone resin, 10-30 percent of sub-spherical silica micro powder and 10-29 percent of loess powder, wherein the sub-spherical silica micro powder and the loess powder are together used as a compound filler, and the addition of the two materials is 39-42 percent of the total material weight of the oil-lubricated coating layer. By adopting the sub-spherical silica micro powder and the loess powder as the compound filler, the invention can obviously improve the tensile strength and the elongation of the roll material, not only takes the effect of improving the adhesion, but also plays a role of resisting corrosion and radiation.

Environment-friendly odorless prefabricated plastic runway coiled material and preparation method thereof
The invention discloses an environment-friendly odorless prefabricated plastic runway coiled material. The coiled material is composed of the following components in parts by weight: 5 to 20 parts ofthermoplastic polyurethane, 0 to 10 parts of ethylene-propylene-diene monomer, 5 to 20 parts of a styrene thermoplastic elastomer, 0 to 5 parts of polypropylene, 20 to 40 parts of calcium carbonate, 25 to 30 parts of naphthenic oil, 1 to 2 parts of an anti-aging agent, 1 to 2 parts of an antioxidant, 1 to 3 parts of an anti-ultraviolet absorbent and 4 to 7 parts of a pigment. The invention furtherdiscloses a preparation method of the environment-friendly odorless prefabricated plastic runway coiled material. Compared with the traditional prefabricated runway coiled material, the prefabricatedrunway coiled material has the advantages of being low in production investment cost, simple in process, free of vulcanization, environmentally friendly, odorless, excellent in physical and chemicalperformance and high in cost performance, and the performance meets the requirements of the new national standard GB36246-2018.
