Description

PVC pre-paved anti-sticking waterproof coiled material

Technical Field

The utility model relates to a waterproof building materials field, in particular to PVC pre-paving anti-sticking waterproofing membrane.

Background

The waterproof roll is mainly used for building walls, roofs, tunnels, highways, refuse landfills and the like, can be curled into a roll-shaped flexible building material product for resisting external rainwater and underground water leakage, is used as a leakage-free connection between an engineering foundation and a building, is a waterproof first barrier of the whole engineering, and plays a vital role in the whole engineering.

The pre-paved waterproof coiled material is suitable for the basement bottom plate and the ground, and refers to the waterproof coiled material paved before the structural construction. Structural concrete is directly poured and tamped on waterproofing membrane, and the self-adhesive layer forms the waterproof layer after concreting with liquid concrete thick liquids reaction and combines with the concrete zero clearance, prevents to scurry water between the layer, improves water-proof effects reliability. However, the pre-laid waterproof roll material on the market at present has some problems, for example, the fusion effect of the self-adhesive layer and the concrete needs to be further enhanced, the waterproof roll material is easy to be damaged when the electric spark for binding the steel bar falls, and the existing method for lap joint construction between the pre-laid waterproof roll materials is to directly bond the two waterproof roll materials by the glue, and the lap joint is very unreliable.

Disclosure of Invention

The utility model provides a PVC spreads waterproofing membrane of anti-sticking in advance, its purpose be solved present spread waterproofing membrane self-adhesive layer in advance and concrete merge the insecure problem of overlap joint between poor, the construction inconvenience, the coiled material.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a PVC pre-paved anti-sticking waterproof roll which characterized in that: seen from the cross section, the anti-sticking;

the anti-sticking isolation sand layer is protection sand with the particle size of 30-60 meshes; the self-adhesive layer is a butyl rubber layer or a hot-melt pressure-sensitive adhesive layer; the fluorocarbon film protective layer is fluorocarbon paint; the polyvinyl chloride base material layer is polyvinyl chloride;

the anti-sticking isolation sand layer is laid on the top of the self-adhesive layer, the fluorocarbon film protective layer is attached to the bottom of the self-adhesive layer, and the polyvinyl chloride base material layer is attached to the bottom of the fluorocarbon film protective layer;

PVC spreads anti-each layer parallel and level of gluing waterproofing membrane in advance on its width direction, and antiseized isolation sand layer of opposite side, self-adhesive layer, fluorine carbon film inoxidizing coating three-layer parallel and level, the terminal surface of its parallel and level is first flush face, polyvinyl chloride base material layer uses first flush face to outwards extend as the benchmark and forms polyvinyl chloride overlap edge.

Preferably, the width of the polyvinyl chloride overlapping edge is 7-9 cm.

Preferably, the thickness of the self-adhesive layer is 0.3-0.5 cm.

The utility model discloses beneficial effect:

1. the utility model discloses increased the fluorocarbon film inoxidizing coating, effectively prevented that the plasticizer in the PVC substrate from migrating the back and taking place chemical reaction with the self-adhesive layer and what lead to comes unstuck.

2. The utility model discloses last self-adhesive layer effect prevents to scurry water with the concrete effective fusion.

3. The utility model discloses it has the antiseized isolation sand bed of one deck to cover on the self-adhesive layer, can play certain anti ultraviolet, ageing-resistant effect, prevents that the workman from gluing the foot when the construction, has further strengthened the fusion effect with the concrete, prevents to prick the electric spark of reinforcing bar and drops to damage waterproofing membrane on the waterproofing membrane, plays the isolation protection effect to the coiled material.

4. The utility model discloses used polyvinyl chloride to replace traditional high density polyethylene, comparatively speaking, polyvinyl chloride's texture is softer, seam that can be inseparabler.

5. The utility model discloses special overlap edge structure overlap joint is more reliable convenient when the construction, and water-proof effects is good, during the overlap joint construction, only needs to set up second waterproofing membrane at first waterproofing membrane's overlap joint edge, welds the heat-seal again and just can reach the lapped purpose.
