The present invention is a waterproof material (sealing material, sealing material)
Extremely durable (high strength)
waterproof cover with elasticity (sealing covering material,
sealing covering). The present invention also relates to a waterproof cover obtained by this manufacturing method. Currently, some types of waterproof covers known in the art have a skeleton (reinforcing material,
reinforcement and a layer of regular bitumen with added fillers. Furthermore, covers are known which are obtained using modified bitumens having elasticity and conventional frameworks made of glass fabrics or glass structures, which modified bitumens are particularly of the polystyrene-polybutadiene-polystyrene-block copolymer type. Contains high molecular weight polymers. However, these known covers have relatively low strength (resistance), elongation at break (elongation at break), and elasticity. 〓〓〓〓〓
The present invention aims to eliminate these drawbacks. The present invention relates to a method for manufacturing a high-strength elastic waterproof cover, which essentially involves impregnating a skeleton made of nonwoven polyester fibers with molten bitumen, and applying bitumen to the surface of the impregnated skeleton.
It consists of applying a mixture of styrene-butadiene-styrene block copolymer (SBS) and resin and finishing the cover. The impregnation of the framework is carried out in a molten bitumen bath, which has a softening point (ring and ball method) of 40-50 °C, a penetration of 80-100 at 25 °C and a oozing phenomenon ( The results of the Oriensistest (exudation phenomena)
It shows less than 0.3mm. The temperature of the impregnation bath is 160~
Maintained at 180° C., the non-woven polyester fiber framework is left in contact with the bitumen for only the amount of time necessary to achieve total saturation. The applicator roller is just coated with a thin film of bitumen. The impregnation rate after dehydration without heating the skeleton is 230-270%. Preparation of bityumen-SBS-resin mixture
A bitumen with a ring and ball softening point of ~50°C and a penetration of 80-100 is stirred with a stirrer (anchor
agitator). The mixing operation must be effective but not too drastic to avoid occlusion of gas or air within the liquid mass, and the temperature must be between 180 and 200°C. The SBS polymer is then introduced in fine powder form into the mixer. The particle size of the powder is 200-800μ, and the mixing ratio is 3-15% by weight, preferably 6-9% by weight, based on the bitumen. This bitumen and polymer are mixed for at least 45 minutes.
Preferably it is carried out for 1 hour. The SBS polymer used in the present invention has good compatibility with bitumen, and as a result, the two can be mixed in a short time by stirring with a weak shear force, resulting in a shortened mixing time. In addition, strong stirring can prevent gas or air from being occluded in the mixture, and it can have a remarkable effect in terms of the product, in that it can improve the strength of the resulting product. . During the mixing operation, a polydiene hydrocarbon resin having a ring and ball softening point of e.g. 70-125°C, preferably 110-120°C and an average molecular weight of 1000-1300,
or polycyclic thermoplastic hydrocarbons based on reactive polydienes with a ring and ball softening point of 80-115°C, preferably 100-110°C and a molecular weight of 600-700 and mean insaturation. Add system resin. The amount of resin added is 2 to 5% by weight, preferably 3% by weight, based on the bitumen. To the bitumen-SBS-resin mixture thus obtained, customary fillers such as limestone, flyash, slate powder or other mineral powders having a particle size of less than 80μ can then be added. The amount of filler is 10 to 50% of the total amount of the mixture.
It varies by weight%, preferably about 40% by weight. The bityumen-SBS-resin mixture is then poured into one or two surfacing containers.
The impregnated scaffold is passed over a roller that is immersed within the bitumen and impregnated on the underside of the skeleton, thereby loading the bitumen onto the underside of the skeleton. At the same time, the upper surface of the skeleton is poured with bitumen, thereby loading the upper surface of the skeleton with bitumen as well. By adjusting these two operations, the thickness of the bitumen on both sides can be made different or the same as desired. The overall thickness of the cover is adjusted by passing the cover between fixed or movable calender rolls. The spacing between the rolls is adjusted depending on the desired thickness. The cover is then subjected to an anti-adhesion protection treatment such as sanding or talc coating, or in the case of an auto-protection cover, a self-protection treatment with colored particles, (granular charcoal), mineral flakes, metal foil, synthetic material flakes, etc. Or for normal finishing operations such as cooling, winding, packaging, etc. The present invention also aims at a waterproof cover having high strength and elasticity as a new industrial product obtained by applying the above-mentioned method. The cover consists essentially of a skeleton made of nonwoven polyester fibers, an elastic bitumen, and a finishing layer. The strength of frameworks made of non-woven polyester fibers is due in particular to the physical bonding forces that exist between the fibers.
and the amount of adhesive etc. for adhesion is:
Relatively small amounts of less than 10% are sufficient. This skeleton made of non-woven polyester fibers is
It has the following properties: Weight: 125-500g, preferably 350g; Temperature resistance: softening point 230-250°C, melting point 255°C; resistance to rotting; aging resistance; corrosion resistance; dimensional stability. ; Minimum water absorption (less than 0.4%); Mechanical bonding between fibers requires only 7% acrylic binder; High breaking strength: fiber length, planting (lashing) and binder; The table below shows the results of various tests;

This bitumen exhibits, for example, the following properties: Ring and ball softening point: higher than 100°C; Penetration at 25°C: 2.5-3.5 mm; No cracking occurs even when bent at low temperatures down to -10°C. No; Elastic modulus with 100% elastic return: Exceeds 2000%. The final composition of such a bitumen is, for example, as follows: 80/100 bitumen: 50% Filler (limestone): 40% SBS block copolymer: 7% Resin: 3% The finishing layer is sand , an anti-adhesive protective layer such as talc or other fine mineral substances, or slate flakes,
It consists of a self-protective layer made of colored particles, metal foil, etc. Thanks to the invention, a waterproof cover can be realized which has particularly significant high strength and elongation at break and has an elasticity which has not yet been achieved with known bitumen covers. As an example, a common waterproof cover obtained by applying the method according to the invention has the following composition: Non-woven polyester fiber framework: 0.350 Kg/ m2 Impregnated bitumen: 0.875 Kg/ m2 Filler content Elastic bitumen: 3.575 Kg/m 2 Surface finish (sand): 0.200 Kg/m 2 Overall weight: 5 Kg/m 2 The strength and elasticity of a waterproof cover having this composition were tested and studied. Tensile test Using a 5cm x 20cm cover specimen, French standard
The tensile strength was measured according to G07-001 and a stress-elongation curve was created. The average tensile strength is
It was 300N/cm and 160N/cm in the transverse direction. The elongation at break was 30-80. The fact that a linear portion was observed in the stress-elongation curve indicates that these specimens have elasticity. The elastic limit is considered to be 6-10%. No such straight sections (ie, elastic phase) were observed in the non-woven polyester cover. Elasticity Test To confirm the elastic limit estimated from the stress-elongation curve of the tensile test, the cover sample was stretched and
The stress was removed and the elastic recovery was measured as a function of time (i.e., elongation-time curve). The maximum elongation, that is, the elastic limit, was approximately 6% when the elongation returned within this range with an error of 0.5%. In a variant, with a slate self-protection layer 〓〓〓〓〓
A cover obtained by the same method has the following composition. Non-woven polyester fiber framework: 0.35Kg/m 2 Impregnated bitumen: 0.875Kg/m 2 Filler-containing elastic bitumen: 3.575Kg/m 2 Sand: 0.100Kg/m 2 Slate flakes: 0.800Kg/m 2 Overall weight: 5.700Kg/m 2 The waterproof cover based on the present invention is suitable for waterproofing (sealing) construction works such as terrace roofs, garages coated with bittyumen, civil engineering foundation work, board work, tunnels, water reservoirs, and dam embankments. used. Furthermore, by mixing a fungicide with the bitiumen, the cover can be used as a waterproof cover for gardens and terrace roofs to prevent root invasion. Of course, the invention is not limited to the embodiments described above, but may include many modifications and variations without departing from the scope of its gist. 〓〓〓〓〓
