Description
Technical Field
The utility model relates to the field of waterproof building materials, in particular to an internally-compounded self-adhesive waterproof coiled material special for TPO/PVC maintenance.
Background
At present, two traditional methods for waterproof maintenance of metal roofs exist:
1. the modified asphalt self-adhesive waterproof coiled materials with the thickness of 1.2 mm-1.5 mm are adopted, and the heat-resistant temperature of the modified asphalt self-adhesive waterproof coiled materials can reach 70 ℃, so that the construction is convenient, but the modified asphalt self-adhesive waterproof coiled materials are not suitable for being exposed and used, and the effective service life of the waterproof function is only 3 years;
2. the modified asphalt waterproof coiled material with the thickness of 3-4 mm is adopted for hot-melting construction, the high temperature resistance can reach 90 degrees, but the hot-melting construction is easy to cause fire, on the other hand, the quality is heavy, the roof bearing pressure is high, the waterproof construction is also not suitable for being exposed, and the effective service life of the waterproof function is about 3-5 years;
3. polyvinyl chloride (PVC) L waterproof coiled materials with full-adhesion construction are adopted, the full-adhesion construction process is complex, and the adhesive is needed to be used for adhesion: the adhesive is coated on both sides of the coiled material and the base layer, and then the coiled material and the base layer are bonded after being cooled for 30 minutes, and the adhesive has the other disadvantage that the adhesive is not environment-friendly and has large smell, but can be used in an exposed way, and the effective service life of the waterproof function is more than 8 years.
In view of this, it is the subject of the present utility model to obtain a waterproof maintenance roll which can be exposed for use and is convenient for construction.
Disclosure of Invention
The utility model provides an internally-compounded self-adhesive waterproof coiled material special for TPO/PVC maintenance, which aims to solve the problems that the existing waterproof coiled material cannot be exposed for use and is inconvenient to construct.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an interior special self-adhesion waterproofing membrane of compound TPO PVC maintenance, its characterized in that:
the cross section of the glass fiber composite material is composed of a first polymer sheet layer, a glass fiber non-woven composite layer, a second polymer sheet layer, a PP+PET non-woven composite layer, a glue self-adhesive layer and an anti-sticking isolation layer in sequence from top to bottom;
the first polymer sheet layer is paved on the top of the glass fiber non-woven composite layer, the second polymer sheet layer is paved on the bottom of the glass fiber non-woven composite layer, the PP+PET non-woven composite layer is arranged on the bottom of the second polymer sheet layer, the adhesive self-adhesive layer is self-adhered on the bottom of the PP+PET non-woven composite layer, and an anti-adhesion isolation layer is arranged on the bottom of the adhesive self-adhesive layer;
the first polymer sheet layer and the second polymer sheet layer are both PVC materials or TPO materials, the glass fiber non-woven composite layer is made of glass fiber non-woven fabrics, the PP+PET non-woven composite layer is made of PP+PET non-woven fabrics, the adhesive self-adhesive layer is thick butyl adhesive, and the anti-adhesive isolation layer is an anti-adhesive isolation film.
Preferably, the thickness of the first polymer sheet layer and the second polymer sheet layer is 0.3-0.5 mm.
Preferably, the thickness of the adhesive self-adhesive layer is 0.2-0.4-mm.
Preferably, the PP+PET non-woven fabric is a non-woven fabric containing PP and PET, and is a finished product available in the market.
The inner composite in the title of the technical scheme refers to the simultaneous use of glass fiber mesh cloth and PP+PET non-woven fabric as an inner composite layer.
The utility model has the beneficial effects that:
polyvinyl chloride (PVC) waterproof coiled materials in the market cannot be directly made into self-adhesive coiled materials for self-adhesive construction because the plasticizer cannot be directly compounded with the self-adhesive materials for use, and the plasticizer is separated out to react with the self-adhesive layer; generally, L-shaped coiled materials with fiber liners are subjected to full-adhesion construction by using an adhesive, but the dimensional stability is poor, the product is easy to expand with heat and contract with cold, and the peripheral edges of the product are warped under the influence of stress, so that the coiled materials are not firmly adhered to a base layer; meanwhile, the existing TPO maintains the specialized self-adhesion waterproof coiled material, the structure is very simple: the butyl adhesive self-adhesive layer is only coated on the homogeneous TPO sheet, and the homogeneous TPO sheet has poor dimensional stability, and the product is also easy to expand with heat and contract with cold and is affected by stress, and the periphery is easy to warp, so that the coiled material and the base layer are not firmly bonded.
Compared with the PVC/TPO coiled material, the waterproof coiled material in the technical scheme has the advantages of good dimensional stability, convenient self-adhesion construction, smoother and smooth sticking after sticking, no edge warping around and improved tensile strength. Wherein, the glass fiber non-woven fabric enhances the dimensional stability of the coiled material, and the PP+PET non-woven fabric is used for improving the dimensional stability; when the polymer sheet layer is PVC, the PP+PET non-woven fabric is also used as an isolation layer of the PVC coiled material and the self-adhesive layer, so that the PVC coiled material and the self-adhesive layer cannot react, and meanwhile, the bonding performance between the self-adhesive layer and the coiled material is improved.
According to the technical scheme, PP+PET+glass fiber is adopted for compounding, so that the dimensional stability is better, the influence of expansion with heat and contraction with cold is small, the material and the base layer are more flatly adhered, and the edge warping is avoided; the material polyvinyl chloride (PVC)/material Thermoplastic Polyolefin (TPO) waterproof coiled material has good heat resistance, can resist high temperature of 115 ℃, and the self-adhesive layer is also self-adhesive by adopting butyl rubber with heat resistance of 110 ℃; the PVC/TPO coiled material has good low temperature resistance, the low temperature resistance can reach-40 ℃, and the self-adhesive layer has low temperature resistance of-25 ℃.
