Abstract
The utility model relates to a tensile flexible felt, which belongs to the field of the waterproof and moisture-proof building materials. The tensile flexible felt consists of a paper base layer, a bitumen mixing layer, a tensile layer and a fastening antisticking layer and the tensile layer is a grid glass fiber cloth layer. The fastening antisticking layer is a plastic film layer and the bitumen mixing layer is an SBS bitumen mixing layer or rubber powder bitumen mixing layer. The bitumen mixing layer and the tensile layer are coated on one or two surfaces of the paper base layer so as to solve the problems that the felt is easily cracked and can not resist tension in the process of construction and the plastic film layer is adopted on the surface to solve the problem the antisticking is applied to the surface after the felt is rolled. The tensile flexible felt has flexibility and also tensile capacity, and has good waterproof and moisture-proof performances, has long service life and has simple production process, and is suitable for waterproof and moisture insulation of the foundations, floors and roofs of various buildings.
Description
Technical field:
The utility model relates to a kind of flexible malthoid of not easy fracture, relates in particular to the flexible malthoid of a kind of tension, belongs to the building material field of waterproof, damp proof insulation.
Background technology:
The ground protection against the tide of existing building engineering, the used constructional materials of roof waterproof, general still the employing by paper tire and the surperficial malthoid that is coated with one deck pitch and makes.Though this malthoid is easy to manufacture, low price, but the greatest problem that this malthoid exists is when natural temperature is low, because the fragility of pitch, be easy to generate the phenomenon of crack or fracture during construction, and make malthoid not have the effect of waterproof, damp proof insulation, the effect of waterproof, damp proof insulation is had a greatly reduced quality.In order to address this problem, have now a kind of flexibility preferably malthoid can prevent to produce the phenomenon of crack or fracture at low temperatures, but the pull resistance of this malthoid is very poor, often occurs tearing phenomenon during use.
Summary of the invention:
The purpose of this utility model is: provides to be difficult for crack or fracture under a kind of low-temperature condition, has flexibility, and the strong flexible malthoid of tension of resistance to tension.
The utility model is to solve the problems referred to above by following technical solution:
The flexible malthoid of this tension is by paper tyre layer, pitch mixed layer, tensile layer and tighten up adherent layer and constitute, it is characterized in that: the one or both sides of paper tyre layer are shaped on the pitch mixed layer, on one deck or layers of asphalt mixed layer, be shaped on tensile layer, be shaped on above the tensile layer and tighten up adherent layer.Described tensile layer is a grid glass layer of cloth.The described adherent layer that tightens up is a plastic film layers.Described pitch mixed layer is SBS pitch mixed layer or rubber powder and asphalt mixed layer.
The utility model compared with prior art has following beneficial effect:
1, brittle failure or phenomenon of rupture do not take place during low-temperature construction, both had flexibility, tensile property is good again.
2, waterproof, damp proof insulation performance are good, long service life.
3, simple in structure, cost of production is low, and production technology is simple.
4, at high temperature surperficial adhesion after the finished product rolling.
Description of drawings:
Fig. 1 simultaneously has pitch mixed layer structural representation again for the paper tire of the flexible malthoid of tension;
Fig. 2 has pitch mixed layer structural representation again for the paper tire two sides of the flexible malthoid of tension;
Among the figure: 1, tighten up adherent layer, 2, tensile layer, 3, the pitch mixed layer, 4, paper tyre layer.
The specific embodiment:
The flexible malthoid of this tension is by paper tyre layer 4, and pitch mixed layer 3 tightens up adherent layer 1 and tensile layer 2 constitutes.Pitch mixed layer 3 by designing requirement can be again at the one or both sides of paper tyre layer 4, pitch mixed layer 3 is mixed and made into by SBS powder or rubber powder and pitch.Have one deck to increase the tensile layer 2 of tensile strength above the pitch mixed layer 3 again, tensile layer 2 is made by glass fiber reticular cloth.The top of tensile layer 2 has one deck to tighten up adherent layer 1 more again, plays fixedly tensile layer 2 and prevents the layer adhesion of rolling rear surface, tightens up adherent layer 1 and made by plastic sheeting.During making, earlier pitch is dissolved, again SBS powder or rubber powder are mixed, make behind the asphalt mixture coated to the one or both sides of paper tyre layer 4, adhesion stress by pitch mixed layer 3 goes up tensile layer 2 again again, tighten up adherent layer 1 and promptly become product answering on the tensile layer 2 again, then rolling finished product.
