Abstract

The invention discloses a waterproof PVC coating having ageing resistance. Raw materials of the waterproof PVC coating comprise, by weight, 80-100 parts of PVC resin, 20-35 parts of alicyclic epoxy resin, 10-25 parts of di-n-octyl o-phthalate, 15-30 parts of calcium carbonate, 10-20 parts of chlorinated polyethylene, 8-15 parts of zinc borate, 5-15 parts of magnesium stearate and 15-25 parts of phosphite. The PVC waterproof coating obtained by optimizing the above component formula is only applied to form a thickness of 0.1-0.3 mm when used, and has the advantages of good waterproof performance, good ultraviolet aging resistance, no shedding after being heat-aged at 120 DEG C for 240 h, good adhesion and long service life.

Description

Technical field [0001] The invention relates to a PVC waterproof material, in particular to a PVC waterproof coating with anti-aging effect. Background technique [0002] Polyvinyl chloride (PVC) is one of the most important and most commonly used man-made polymers, mainly because it has great variability. In the process of manufacturing PVC products, it can be used for different purposes and needs. Plasticizers and additives to change its physical and chemical properties. The biggest feature of PVC is that after adding liquid plasticizer, the glass transition temperature will begin to drop. Because of plasticization, semi-rigid to soft materials with a wide range of elasticity can be prepared, which is practical for soft PVC the reason. Existing PVC waterproof inflatable fabrics are widely used in inflatable life jackets, chemical protective clothing, oxygen bags, inflatable cushions, air beds, inflatable tents, airbags, hovercraft, and waterproof and moisture-permeable high-e...
