Description
Technical Field
The utility model belongs to the technical field of rubber products, and relates to a corrosion-resistant pre-vulcanized rubber plate.
Background
The presulfiding is also called semi-vulcanization, and is an alkalizing process of adhering a rubber plate which is vulcanized by heating in advance to a liner pipe or a pipe fitting by using an adhesive, in general, the presulfided rubber plate is in a single-layer structure, and is cut into a whole piece which is matched with the area of the liner surface during adhering, the flexible deformation of the material is utilized to be adhered to the liner surface, and when the inner wall of a pipeline with a larger inner diameter is constructed, the whole piece construction can cause irregular edge trimming due to the flexibility of the material or wrinkles due to uneven tension of the whole piece material, so that the rubber plate is required to be cut into pieces during large-area construction or irregular area construction, and then the liner is spliced to form the liner, but the mode can cause insufficient corrosion resistance strength at a spliced seam, and the liner surface is difficult to form complete protection.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provide a corrosion-resistant pre-vulcanized rubber plate, and the technical problem to be solved by the utility model is how to improve the corrosion resistance of a lining surface.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a corrosion-resistant rubber slab that pre-vulcanizes, its characterized in that includes rubber backing plate, rubber face welt and curtain line net layer, rubber backing plate and rubber face welt are the rectangular plate, and the polylith rubber backing plate splice into the backing layer with attached face adaptation, the polylith rubber face welt splice into the surface lining layer with backing layer surface adaptation, curtain line net layer is located between backing layer and the surface lining layer.
Further, the rubber bottom lining plate and the rubber surface lining plate are distributed in a staggered mode.
Further, the rubber bottom lining plate and the rubber surface lining plate are both butyl rubber plates.
Further, the thickness of the rubber bottom lining plate is larger than that of the rubber surface lining plate.
When the pre-vulcanized lining of the inner wall of the different-property irregular or large-inner-diameter pipeline is constructed, the whole piece of construction is easy to cause the conditions of wrinkling, irregular butt joint, local packing and the like, therefore, the scheme adopts a double-layer structure, and a cord wire mesh is used as a connecting layer between the rubber bottom lining plate and the rubber surface lining plate, so that the peeling strength between the double layers is increased, the exposure of a splicing gap is reduced, the corrosion probability of a corroded object of a lining surface is greatly reduced, and the corrosion resistance is improved.

Fig. 1 is a schematic diagram of a staggered splicing state of a rubber bottom lining plate and a rubber surface lining plate.
Fig. 2 is a schematic view of the layered structure of the liner after the pre-cure construction.
In the figure, 1, a rubber bottom lining plate; 2. a rubber surface lining board; 3. curtain wire mesh layer.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
The corrosion-resistant pre-vulcanized rubber plate shown in fig. 1 and 2 comprises a rubber bottom lining plate 1, a rubber surface lining plate 2 and a curtain wire net layer 3, wherein the rubber bottom lining plate 1 and the rubber surface lining plate 2 are rectangular plates, a plurality of rubber bottom lining plates 1 are spliced into a bottom lining layer matched with an attaching surface, a plurality of rubber surface lining plates 2 are spliced into a surface lining layer matched with the surface of the bottom lining layer, and the curtain wire net layer 3 is positioned between the bottom lining layer and the surface lining layer.
The rubber bottom lining board 1 and the rubber surface lining board 2 are distributed in a dislocation way. The rubber bottom lining plate 1 and the rubber surface lining plate 2 are both butyl rubber plates, and the thickness of the rubber bottom lining plate 1 is larger than that of the rubber surface lining plate 2.
During construction, firstly, the rubber bottom lining plate 1 is paved, the rubber bottom lining plate 1 is heated, glue is coated on the surface to be adhered, after the rubber bottom lining plate 1 is paved, the curtain wire net layer 3 is paved on the surface of the rubber bottom lining plate, after the curtain wire net layer 3 is paved, the surface of the rubber bottom lining plate 1 is heated, finally, the rubber surface lining plate 2 is paved in a staggered mode, and interlayer bonding strength is enhanced by adopting a presulfiding mode.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
