Abstract

The invention relates to a polyvinyl chloride geomembrane modified by nitrile-butadiene rubber, belonging to the technical field of the geomembrane. The polyvinyl chloride geomembrane modified by the nitrile-butadiene rubber is characterized in that the mixture ratio composition of the geomembrane takes polyvinyl chloride resin 100 as reference, and the geomembrane comprises the components based on parts by weight: 20-50 dioctyl phthalate, 2-10 dioctyl adipate, 2-10 epoxidized soybean oil, 2-5 heat stabilizer, 1-5 nitrile-butadiene rubber, 10-20 calcium carbonate, 0.1-0.5 stearic acid, 1-5 white carbon black and 1-6 talcum powder. The modified polyvinyl chloride geomembrane has the advantages of good hand feeling of rubber, high toughness and strength, excellent sealing performance, saving cost, being beneficial to environmental protection, being long in service life, and the like.

Description

technical field

[0001] The invention belongs to the technical field of geomembranes, in particular to a polyvinyl chloride geomembrane modified by nitrile rubber. Background technique

[0002] Sea reclamation refers to building dikes on beaches or shallow seas to isolate external seawater, and draining and draining the water in the dikes to make them land projects.

[0003] At present, the common geomembranes on the market are prone to damage during engineering construction, or are punctured and damaged by stones or other sharp objects, or are bulged when they are subjected to water pressure and earth pressure due to lack of restraint support. , or the stress concentration caused by the jacking of the lower gas or liquid during the filling process leads to damage. At the same time, factors such as temperature, gravity, soil displacement and water level changes are also likely to cause excessive stretching, tearing or abrasion of the geomembrane. , These will affect the use ...
