Abstract

The invention provides a viscous waterproof coiled material. The viscous waterproof coiled material comprises a mixed asphalt layer composed of asphalt and a blank base. Two sides of the mixed asphalt layer are respectively provided with an upper isolation layer and a lower isolation layer. An adhesive layer is arranged at a lower part of the lower isolation layer. The adhesive layer comprises hot melting parts producing viscosity at a high temperature and self-adhesion parts having inherent viscosity, wherein the hot melting parts and the self-adhesion parts are arranged alternately in the same plane. A protective film is coated on the surface of the adhesive layer. The viscous waterproof coiled material is convenient for construction and has a wide application range.

Description

A kind of viscosity waterproof roll

Technical field

The present invention relates to the building waterproof coil field, especially a kind of viscosity waterproof roll that comprises tire base and bituminous water-proof coating.

Background technology

Waterproof roll mainly is to locate for construction wall, roofing and tunnel, highway, refuse landfill etc., play a kind of flexible building material product that is curled into web-like of resisting extraneous rainwater, ground water seepage, being connected as ne-leakage between engineering foundation and the building, is the barrier of whole engineering waterproofing.

Present waterproof roll is mainly asphalt water-proof coiled material, mainly is made of bitumen layer, separation layer, and bitumen layer mainly is made of the pitch that is attached to basic tire both sides, and separation layer mainly is made of polyethylene film, fine sand or mineral pellet etc.

When traditional waterproof roll is laid, need to make its surface melting by baking, to be covered on engineering surface in engineering; Because this process comparatively bothers, therefore a kind of self-adhesive waterproof roll material has appearred at present, and the face that pastes of this coiled material itself has viscosity, and coated with protective film, when needs paste, only need throw off diaphragm, coiled material directly can be covered on engineering surface, need not baking and heat, very convenient; Yet the boundary of works area of this kind coiled material comparatively limits to, and is lower for surface flatness, under heavy contamination or humidity, the oil pollution environment, all is difficult to construction.

Summary of the invention

For the problems referred to above, the object of the present invention is to provide a kind of viscosity waterproof roll, this kind viscosity waterproof roll facility of not only constructing, and have comparatively wide range of application.

The technical solution adopted for the present invention to solve the technical problems is: this viscosity waterproof roll comprises by pitch and basic tire and consists of the mix asphalt layer, described mix asphalt layer both sides are respectively separation layer and lower separation layer, described lower separation layer below also is provided with one deck adhesion layer, and described adhesion layer is included in and alternatively distributedly in the same plane can at high temperature melts and produce the hot melt section of viscosity and the self-adhesive part with inherent viscosity; Described adhesion layer surface also pastes layer protecting film.

As preferably, described hot melt section and self-adhesive part all are strip, along laterally or vertically equidistantly being alternately distributed of described adhesion layer plane.

As preferably, described hot melt section is made of polyethylene film.

Beneficial effect of the present invention is: the lower surface of this viscosity waterproof roll is owing to have hot melt section and self-adhesive part, therefore, under adverse circumstances, can such as common waterproof roll, adopt roasting mode to be covered on engineering surface, under conventional environment, then can directly be covered on engineering surface by self-adhesive part, therefore, not only construction is convenient, and has more wide range of application.

Description of drawings

Fig. 1 is the schematic cross-section of an embodiment of intrinsic viscosity waterproof roll;

Fig. 2 is the lower surface view of Fig. 1 embodiment.

Among the figure 1, the mix asphalt layer; 2, upper separation layer; 3, lower separation layer; 4, adhesion layer; 41, hot melt section; 42, self-adhesive part.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples:

Fig. 1, embodiment illustrated in fig. 2 in, this viscosity waterproof roll comprises by pitch and basic tire and consists of mix asphalt layer 1, described mix asphalt layer 1 both sides are respectively separation layer 2 and lower separation layer 3, described lower separation layer 3 belows also are provided with one deck adhesion layer 4, described adhesion layer 4 is included in the alternatively distributed self-adhesive part 42 that can at high temperature melt and produce the hot melt section 41 of viscosity and have inherent viscosity in the same plane as shown in Figure 2; Described adhesion layer 4 surfaces also paste layer protecting film (not shown, as can to adopt oiliness paper).

As shown in Figure 2, described hot melt section 31 and self-adhesive part 42 all are strip, along laterally equidistantly being alternately distributed of described adhesion layer 4 planes.

The lower surface of above-mentioned viscosity waterproof roll is owing to have hot melt section 41 and self-adhesive part 42, therefore, under adverse circumstances, can be such as common waterproof roll, adopt roasting mode, be 41 fusings of hot melt section, and be covered on engineering surface, under conventional environment, then can directly be covered on engineering surface by self-adhesive part 42, therefore, not only construction is convenient, and has more wide range of application.

The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
