Description
Technical Field
The utility model belongs to the technical field of waterproofing membrane, more specifically relates to an anti-yellowing antiskid self-adhesion pitch waterproofing membrane.
Background
The technical specification GB/T50693-2012 proposes that a waterproof cushion layer should be selected for the tile roof, and simultaneously proposes that the surface of the waterproof cushion layer should have anti-skid performance or take anti-skid measures. However, china still does not make clear requirements on the anti-skid performance of the anti-skid coiled material. The antiskid coiled material on the market adopts various antiskid forms, such as arranging raised antiskid on a polyethylene cross film, adopting non-woven fabric antiskid, adopting rubber and raised antiskid thereof and the like. However, the existing anti-slip forms have some problems, such as:
the polyethylene cross film is provided with bulges for skid resistance. The anti-skid film has good anti-skid property, but the polyethylene cross film has poor dimensional stability and low tensile strength, is easy to be eroded by oil in asphalt to cause yellowing, and the problems cause poor waterproof property and unattractive appearance of the coiled material.
Non-woven fabrics are adopted for skid prevention. The non-woven fabric is not a compact waterproof layer, liquid water enters pores of the non-woven fabric after the non-woven fabric meets water, and the non-woven fabric is in a humid water environment for a long time and is prone to mildew, rot and the like. In addition, asphalt oil easily seeps out of pores of the non-woven fabric, and aging of the waterproof roll is accelerated.
Adopts rubber and the bulges thereof to prevent slipping. This form also provides good slip resistance but the rubber becomes large and tends to shrink after application, particularly where shrinkage at the overlap will cause water seepage. In addition, the mechanical strength of the rubber is low, and the tensile strength of the coiled material is low.
Based on the above, a new self-adhesive asphalt waterproof coiled material with yellowing resistance, excellent tensile strength and slip resistance is urgently needed to be provided.
