Abstract
The utility model provides a double-polyester (PE) waterproof roll which is characterized by comprising a main waterproof layer made from linear low-density polyethylene; the upper surface and the lower surface of the main waterproof layer are respectively provided with a polypropylene non-woven fabric layer; and a strengthening layer is arranged in the middle of the main waterproof layer. The polypropylene non-woven fabric layers are arranged on the surfaces of the main waterproof layer, so that the double-PE waterproof roll has cement adhesive property, the cement can be directly used for bonding, the waterproof roll is not influenced by the water content of a base layer in a construction process, and construction can be carried out as long as no water is available; and the waterproof roll has rough surfaces and high friction coefficient, thus being directly buried into sand when being applied to water conservancy project, and having good stability.
Description
Technical field
The utility model relates to a kind of waterproof roll, particularly relates to a kind of double focusing ester PE waterproof roll.
Background technology
Waterproof roll is a kind of construction material commonly used in construction, and in the construction of building, many local paved waterproof rolls in advance that need are as roof, toilet, basement etc.At first common waterproof roll need to do base treatment when construction, require basic unit solid, smooth, and without ponding, the moisture content of basic unit must be lower, perhaps the brushing base treatment agent.The construction method of the most often using is hot melt, large of waterproof roll need to be adopted lower surface and the substrate surface of the special-purpose hot-melting tool baking such as hot melt spray gun or hot-melt asphalt car waterproof roll during operation, make the pitch of coiled material surface shinny during to molten condition, use the pressure roller roll extrusion, make itself and basic unit or coiled material bonding firmly.This method for paving complex procedures, speed of application is slow, and waterproof roll can not be well bonding with the top layer cement of basic unit and waterproof roll surface coverage, affects long-term waterproof effect.
The utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provide a kind of and can mat formation when basic unit's moisture content is higher, with cement layer bonds, speed of application is fast double focusing ester PE waterproof roll.
The purpose of this utility model reaches by following technical measures:
Double focusing ester PE waterproof roll is characterized in that: comprise the main water barrier that LLDPE forms, the upper and lower surface of main water barrier is respectively equipped with the nonwoven polypropylene fabric layer.LLDPE is LLDPE, and its extensibility, impermeability, flexibility, puncture resistance, resistance to low temperature are better.And the nonwoven polypropylene fabric rough surface, non-woven fabrics fiber is random chi structure, forms three-dimensional mesh, be fit to multiple material bonding, especially directly bonding in process of setting with cement material, as long as just can construct without open fire, combination property is good, and tensile strength is high, and impermeability is strong, low temperature flexibility is good, the coefficient of expansion is little, easily bonds, and the coefficient of friction I directly is located in sand and is used, stable and reliable for performance, be a kind of nontoxic, free of contamination Green Product.
As a kind of improvement, be provided with strengthening layer in the middle of main water barrier.
As a kind of concrete preferred version, strengthening layer is long filament polyester carpet veneer or fiberglass gridding cloth layer.Long filament polyester carpet veneer or fiberglass gridding cloth layer can obviously strengthen the intensity of waterproof roll as strengthening layer, improve particle-resistant and pierce through performance, reach high-tensile, the lancinating requirement of high resistance.
Owing to having adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) the utility model belongs to polymer membranes, by its surface, the nonwoven polypropylene fabric layer being set makes it have cementitious performance, can be directly bonding with cement, therefore be not subjected to the impact of basic unit's moisture content in work progress, as long as can construct without open fire.
(2) coiled material surface that provides of the utility model is coarse, coefficient of friction is large, when hydraulic engineering is used, can directly be embedded in sand, has good stability.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model double focusing ester PE waterproof roll embodiment 1;
Accompanying drawing 2 is structural representations of the utility model double focusing ester PE waterproof roll embodiment 2.
The specific embodiment
Embodiment 1: as shown in Figure 1, double focusing ester PE waterproof roll comprises the main water barrier 2 that LLDPE forms, and the upper and lower surface of main water barrier 2 is respectively equipped with nonwoven polypropylene fabric layer 1.LLDPE is LLDPE, and its extensibility, impermeability, flexibility, puncture resistance, resistance to low temperature are better.And the nonwoven polypropylene fabric rough surface, non-woven fabrics fiber is random chi structure, forms three-dimensional mesh, be fit to multiple material bonding, especially directly bonding in process of setting with cement material, as long as just can construct without open fire, combination property is good, and tensile strength is high, and impermeability is strong, low temperature flexibility is good, the coefficient of expansion is little, easily bonds, and the coefficient of friction I directly is located in sand and is used, stable and reliable for performance, be a kind of nontoxic, free of contamination Green Product.
Embodiment 2: as shown in Figure 2, double focusing ester PE waterproof roll comprises the main water barrier 2 that LLDPE forms, and the upper and lower surface of main water barrier 2 is respectively equipped with nonwoven polypropylene fabric layer 1.LLDPE is LLDPE, and its extensibility, impermeability, flexibility, puncture resistance, resistance to low temperature are better.And the nonwoven polypropylene fabric rough surface, non-woven fabrics fiber is random chi structure, forms three-dimensional mesh, be fit to multiple material bonding, especially directly bonding in process of setting with cement material, as long as just can construct without open fire, combination property is good, and tensile strength is high, and impermeability is strong, low temperature flexibility is good, the coefficient of expansion is little, easily bonds, and the coefficient of friction I directly is located in sand and is used, stable and reliable for performance, be a kind of nontoxic, free of contamination Green Product.
In the present embodiment, be provided with strengthening layer 3 in the middle of main water barrier 2.Strengthening layer 3 is long filament polyester carpet veneer.Certainly, also can adopt fiberglass gridding cloth to make strengthening layer 3.Strengthening layer 3 can obviously strengthen the intensity of waterproof roll, improves particle-resistant and pierces through performance, reaches high-tensile, the lancinating requirement of high resistance.
Claims (3)
