Title of Invention\n\nBituminous Waterproof Material  \n# 2.   Claim\n\nIn the case of nonwoven cloth made of continuous filament yarn of thermo-plastic synthetic fiber,a bituminous waterproof base material characterizedby impregnating a nonwoven cloth having anisotropy(tensile strength ratio ofvertical/lateral direction)in the range of 1.3 -2.5,mixed high and lowdensity regions,unit weight in the range of 50-300g/m²and tensilestrength in the vertical direction in the range of 10-70g/cm/m²with abituminous composition.  \n# 3.  Detailed Description of the Invention\n\nThis invention pertains to a bituminous waterproof base material for theproduction of waterproof construction reinforcing material impregnated withbituminous substances such as asphalt,etc.  \nFor the previously used waterproof construction material impregnated withbituminous substances and used mainly on the rooftop of buildings,jutefabric,cotton fabric,paper,glass fiber mat,etc.,have been used.Thesebase materials have advantages and disadvantages in the characteristics,andthey are not necessarily satisfactory waterproof construction materials.Inorder to eliminate those shortcomings,a nonwoven cloth comprising a PVA typesynthetic fiber has been proposed,and consequently,the shortcomings havebeen eliminated to some extent,but the base cloth has the following  \nshortcomings since it is allowed to hold the nonwoven cloth state by using abinder(synthetic resin emulsion and natural polymeric glue).  \n(1)The portion with a large amount of binder adhered prevents asphaltfrom penetrating allowing water to penetrate through causing a leak at thetime of rain.Still,there is a worse problem that the amount of binderadhering is difficult to adjust causing uneven binder adhesion,and  \nconsequently,the portion with a small amount of binder is impregnated with alarge amount of asphalt,whereas in the portion with a large amount of binder,the amount of asphalt is small promoting not only a leak but also uneventensile or tearing strength.  \n(2)As a waterproof construction reinforcing material,variouscharacteristics are required.Especially in the case of mechanical  \ncharacteristics,the tensile strength is certainly important,and at the sametime,the tearing resistant force is important with respect to the preventionof crack formation of buildings.With respect to this point,it is difficultto obtain a desirable base cloth if the binder described above is used.Aswell-known,it is extremely difficult to obtain satisfactory tensile strengthand tearing strength at the same time by this previously known method.  \nSpecifically,if the amount of binder is increased to obtain a satisfactorytensile strength,the tearing strength is reduced.  \n(3)The base cloth is glued along the whole surface,as a result,eachlayer starts to be peeled off gradually at weak bonding points if tensileforce is applied on the base cloth,and consequently,it causes elongation andloosening which is a specific problem of nonwoven cloth.This problemapparentiy means that it lacks the force to hold sufficiently against theforce generated by cracks on the cei","cbCaicvmU5VPnY3h","https://ap.wps.com/l/cbCaicvmU5VPnY3h","pdf",1002539,"English","# Title of Invention\n# Claim\n## Nonwoven anisotropy and mechanical requirements\n## Bituminous impregnation composition\n# Detailed Description of the Invention\n## Background and limitations of prior base materials\n## Problems with binder distribution\n## Tensile-tear strength tradeoff\n## Peeling/elongation under tensile load\n## Core gist of the invention\n## Discovery of improved properties after impregnation","[{\"question\":\"What is the main purpose of the claimed bituminous waterproof base material?\",\"answer\":\"To serve as a waterproof base material for producing waterproof construction reinforcing material impregnated with bituminous substances such as asphalt.\"},{\"question\":\"How does the invention define the required nonwoven cloth structure?\",\"answer\":\"The nonwoven base cloth uses continuous filament thermoplastic synthetic fiber with anisotropy (vertical/lateral tensile strength ratio 1.3–2.5), mixed high/low density regions, and specified unit weight and vertical tensile strength ranges.\"},{\"question\":\"Which problems with prior binder-based nonwoven approaches does the invention aim to solve?\",\"answer\":\"It targets uneven impregnation caused by binder distribution, the difficulty of achieving both satisfactory tensile and tearing strengths simultaneously, and peeling/elongation at weak bonding points under tensile force.\"}]","Bituminous Waterproof Material | PDF",1789966418]
