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
The invention belongs to the geomembrane technical field, particularly relate to a kind of acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane.
Background technology
Reclaim land from the sea and promptly on seabeach or shallow sea, build embankment isolating exterior seawater, and the water of discharging and draining in the embankment makes the engineering that becomes land.
At present, geomembrane common on the market destroys in engineering construction is used easily; Or destroyed by the puncture of stone or other cusped edge things, or owing to lack the constraint support, broken by drum when bearing water pressure and earth pressure; Or the jacking generation stress concentration that in the hydraulic reclamation process, receives lower floor's gas or liquid causes destroying; Factors such as simultaneous temperature, gravity, land movement and change of level also make geotechnological film produce easily and excessively stretch, tear or abrade, and these all can have influence on the result of use of geomembrane in various degree, reduce its work-ing life; And then improve the input cost again of enterprise, cause the certain economic loss.
Summary of the invention
The present invention provides a kind of acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide and a kind ofly have that toughness height, intensity are big, the polyvinyl chloride geomembrane of good airproof performance; Solve the geomembrane goods and be prone to the disruptive situation in use; Effectively improve the work-ing life of geomembrane; The saving fund helps a kind of acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane of characteristics such as environmental protection.
The present invention for solving the technical scheme that technical problem adopted that exists in the known technology is:
A kind of acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane is characterized in: the proportioning of geomembrane is formed, and is benchmark with PVC RESINS 100, contains following composition weight and does
DOP 20-50
Octyl adipate 2-10
Epoxy soybean oil 2-10
Thermo-stabilizer 2-5
Paracril 1-5
Lime carbonate 10-20
Triple Pressed Stearic Acid 0.1-0.5
WHITE CARBON BLACK 1-5
Talcum powder 1-6
The present invention can also take following technical scheme:
Described acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane is characterized in: the proportioning of geomembrane has colorant in forming.
Described acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane is characterized in: thermo-stabilizer is the stablizer that liquid stabilisers and metallic soap class stablizer are composited.
Described acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane is characterized in: metallic soap class stablizer is the stablizer that barium stearate and Zinic stearas are composited.
Our company adopts that the modification geomembrane of two-way stretch calendering technology production has that tensile strength is good, shock strength is high, good airproof performance, acid and alkali-resistance, characteristic such as heat-resisting, weather-proof, wear-resistant, in the hydraulic reclamation engineering is reclaimed fields from the sea in the manufacturing district, carries out widespread use.
The present invention substitutes the part DOP with Octyl adipate in plasticiser system.As plasticized modifier polyvinyl chloride geomembrane is carried out modification with paracril.
In the above-mentioned prescription: (1) substitutes the part DOP with low temperature resistant softening agent Octyl adipate, strengthens the resistance to low temperature of geomembrane.(2) as plasticized modifier polyvinyl chloride geomembrane is carried out modification with paracril.Because polyvinyl chloride resin has certain polarity, and contain a large amount of polar links in the paracril molecule, externally show extremely strong polarity,, and form a kind of special two phase structure so consistency is very good during with the PVC blend.In PVC/ paracril co-mixing system, globular paracril particle is dispersed in and is " island " structure in the PVC matrix, and the PVC matrix is external phase.Rubber particles can bring out crazing and shear zone when receiving impact, bending; Form crackle and absorb energy; And when crack propagation, the expansion that elastic deformation stops crackle can take place again in rubber particles, thereby makes that toughness, the intensity of the polyvinyl chloride geomembrane after the modification are greatly strengthened.
Advantage and positively effect that the present invention has are:
Acrylonitrile butadiene rubber modified polyvinyl chloride geomembrane is owing to adopted brand-new technology scheme of the present invention; Toughness is high, intensity is big, the polyvinyl chloride geomembrane of good airproof performance, solves the geomembrane goods and is prone to disruptive situation, the work-ing life of effectively improving geomembrane in use; The saving fund is beneficial to environmental protection.Product of the present invention has that tensile strength is good, shock strength is high, good airproof performance, acid and alkali-resistance, characteristic such as heat-resisting, weather-proof, wear-resistant, can in the hydraulic reclamation engineering of reclaiming fields from the sea, carry out widespread use.
The polyvinyl chloride geomembrane of the present invention after modification has the good hand touch of rubber, and toughness is big, intensity is high, and sealing property is superior, and the saving fund is beneficial to environmental protection, improved the work-ing life of polyvinyl chloride geomembrane.
