Description
Technical Field
The utility model relates to a waterproof engineering technical field specifically is a plane waterproof construction.
Background
At present, waterproof coating materials are mainly applied to sealing and waterproofing treatment of large-area and detail nodes of buildings, the main construction application modes mainly comprise two types of mechanical spraying and manual coating, a base surface is treated before construction, a scraper knife and a steel wire brush are used for carrying out laitance and loose and soft base layer cleaning on the base surface, the waterproof coating materials can be coated or sprayed after being wetted by water once after the cleaning is finished, the waterproof coating materials with different times are coated or sprayed according to the characteristics of different materials, and the non-woven fabric is basically not used for reinforcement treatment during large-area construction application. When the waterproof construction of large tracts of land was used, waterproof coating film layer was easily torn by foreign matter such as sharp ware fish tail or by nails, leads to the waterproof layer very easily to be torn, leads to the waterproof layer damage from some to become the face, causes to leak and scurries water. Therefore, it is urgent to find a plane waterproof structure which has strong tearing resistance and is not easy to cause large-area waterproof failure due to point-to-surface damage of the waterproof layer.
Disclosure of Invention
In order to solve the above technical problem that exists among the prior art, the utility model provides a waterproof structure of plane can be realized through following scheme:
a plane waterproof structure comprises at least one layer of waterproof coating and at least one layer of tire body, wherein at least one layer of tire body is a sheath-core composite long fiber tear-resistant cloth.
The tyre body also comprises non-woven fabrics and/or mesh fabrics. The grid cloth has excellent physical and mechanical tensile properties and construction conforming application performance; the non-woven fabric has excellent ductility and permeability, and can improve the tensile property of the waterproof coating and improve the surface flatness of sealant construction when being used with the waterproof coating in a compounding way.
The sheath-core composite long fiber tear-resistant cloth is composed of sheath-core composite long fibers.

As shown in fig. 4, 5 and 6, the sheath-core composite long fiber is provided with an inner layer 10 and an outer layer 9, the outer layer 9 is wrapped on the periphery of the inner layer 10, so that the inner layer 10 and the outer layer 9 are not easy to separate, and meanwhile, when the sheath-core composite long fiber anti-tear cloth is manufactured, only the outer layer 9 is subjected to hot melt bonding, the effect of mutual hot melt bonding of the same material is better than that of hot melt bonding between two different materials, so that the connection strength between fibers of the sheath-core composite long fiber anti-tear cloth is improved, and the anti-tear strength is improved.
The cross section of the sheath-core composite long fiber is concentric circle, eccentric circle or special-shaped cross section.
The cross section of the sheath-core composite long fiber is concentric and circular.
As shown in fig. 4, the cross section of the sheath-core composite long fiber is preferably concentric, the inner layer 10 and the outer layer 9 are concentric, so that the thickness of the outer layer 9 is uniform, and when the sheath-core composite long fiber tear-resistant cloth is manufactured, the fusion depth between the outer layers 9 can be conveniently controlled by controlling the temperature, pressure and time process parameters, so as to improve the tensile strength of the sheath-core composite long fiber tear-resistant cloth.
The inner layer is made of polyester materials, and the outer layer is made of one of polyamide, polyethylene, polypropylene or modified polyester materials.
The polyester has the characteristics of high modulus and high-temperature dimensional stability, the tensile strength and the high-temperature dimensional stability of the sheath-core composite long fiber can be improved by using the polyester as the inner layer of the sheath-core composite long fiber, the melting point of the polyamide, the polyethylene, the polypropylene or the modified polyester used for the outer layer 9 is lower than that of the polyester used for the inner layer 10, when the sheath-core composite long fiber is used for manufacturing the sheath-core composite long fiber anti-tear cloth, the hot melting temperature is controlled between the melting points of the materials of the inner layer and the outer layer, the outer layer 9 can be melted, the inner layer 10 can be kept in a solid state, the whole fiber is prevented from being fused, and the hot melting bonding strength and the anti-tear strength of the sheath-tear cloth of the.
The weight of the sheath-core composite long fiber tear-resistant cloth per square meter is 20-200 g. When the weight of each square meter of the skin-core type composite long fiber anti-tearing cloth is more than 200 grams, the internal pores are less, the combination with the waterproof coating is not facilitated, the elongation of the skin-core type composite long fiber anti-tearing cloth is reduced when the gram weight of the skin-core type composite long fiber anti-tearing cloth is increased, the elongation is reduced, and when the weight of each square meter of the skin-core type composite long fiber anti-tearing cloth is less than 20 grams, the strength of the skin-core type composite long fiber anti-tearing cloth is lower.
Preferably, still set up the protective layer in the outermost surface layer outside, can also set up the protective layer in the outermost surface layer outside to protection rubber state waterproof coating and matrix avoid it to receive the destruction of external ultraviolet ray, sharp object fish tail, influence water-proof effects. The protective layer may be a cement mortar or uv resistant coating. The hardness of the cement mortar is higher after solidification, the rubber-state waterproof coating can be effectively protected from being damaged by scratches and the like, the ultraviolet-resistant coating can prevent the waterproof coating from being aged due to ultraviolet irradiation, the anti-aging capacity of the waterproof layer is enhanced, and the service life of the waterproof layer is prolonged.
The anti-tearing cloth made of the skin-core composite long fiber has the characteristics of high modulus, good elasticity, high bonding strength between fibers, good tear resistance, high thermal stability and the like, and a plane waterproof structure formed by compounding and matching the anti-tearing cloth with waterproof paint not only has high physical and mechanical properties, but also can still keep high mechanical strength through the characteristics of the skin-core composite long fiber after being punctured by foreign matters such as nails and the like, and prevents the puncture hole from being further enlarged. The skin-core type composite long fiber tear-resistant cloth has a high specific surface area, is good in binding property with waterproof coating, can be better integrated, and improves the integrity of the whole structure.
Compared with the prior art, the utility model discloses the technological effect of creation is embodied in:
the utility model discloses a plane waterproof construction, through adopting the anti cloth of tearing of the compound long fiber of skin-core type and compound collocation with water proof coating, full play the anti cloth's of tearing of the compound long fiber of skin-core type modulus height, elasticity is good, the fibre is bonding strength high each other, tear resistance is good, thermal stability is high, with characteristics such as water proof coating associativity is good, the plane waterproof construction who obtains not only has higher physical mechanical properties and good wholeness, can also be after being stabbed by foreign matters such as nail, still can keep higher mechanical strength, and prevent to stab the hole and further enlarge, thereby avoid causing large tracts of land waterproof failure by some to the face waterproof layer damage.
