Abstract
The invention relates to a polyvinyl chloride salt film modified by butadiene nitrile rubber. The invention belongs to the technical field of polyvinyl chloride films. A polyvinyl chloride salt film modified by butadiene nitrile rubber is characterized in that the polyvinyl chloride salt film comprises the following components by weight: 100 parts of polyvinyl chloride resin, 10-40 parts of dioctyl phthalate, 2-10 parts of epoxy soybean oil, 2-12 parts of dioctyl adipate, 2-5 parts of heat stabilizers, 1-4 parts of carbon black, 0.1-0.8 parts of 4,4-isopropylidene diphenol, and 1-10 parts of butadiene nitrile rubber. The invention has the advantages of large strength, high toughness, excellent sealing performance, rubber handle, benefit to environmental protection, and long service life.
Description
Technical field
The invention belongs to the polychloroethylene film technical field, particularly relate to a kind of acrylonitrile butadiene rubber modified polyvinyl chloride salt film.
Background technology
At present, the polyvinyl chloride salt film of known technology mainly is to be increased auxiliary agents such as softening agent, stablizer, carbon black by PVC RESINS, through the polyvinyl chloride film that mixes, plastifies, makes after the processes such as calendering.Wherein, softening agent is main with DOP, and Octyl adipate is auxilliary as the low temperature softening agent, the plasticity of reinforced polyvinyl chloride resin.But salt film with this understanding, intensity and poor toughness, and feel is bad, exists to be prone in the use break, thus make and technical problem such as significantly reduce in work-ing life of salt film.
Summary of the invention
The present invention provides a kind of acrylonitrile butadiene rubber modified polyvinyl chloride salt film for solving the problem that prior art exists.
The object of the invention provides a kind ofly to be had that intensity is big, toughness is high, sealing property is superior, the feel of rubber, helps the acrylonitrile butadiene rubber modified polyvinyl chloride salt film of characteristics such as environmental protection, long service life.
The present invention carries out modification as plasticized modifier to polyvinyl chloride salt film 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 salt film after the modification are greatly strengthened.
The acrylonitrile butadiene rubber modified polyvinyl chloride salt film of the present invention adopts following technical scheme:
A kind of acrylonitrile butadiene rubber modified polyvinyl chloride salt film is characterized in: the weight proportion of each component of polyvinyl chloride salt film is:
PVC RESINS 100;
DOP 10-40;
Epoxy soybean oil 2-10;
Octyl adipate 2-12;
Thermo-stabilizer 2-5;
Carbon black 1-4;
UV-531 or 2-hydroxy-4-methyl UVNUL MS-40 0.1-0.6;
4,4-isopropylidene bis-phenol 0.1-0.8;
Paracril 1-10.
The acrylonitrile butadiene rubber modified polyvinyl chloride salt film of the present invention can also adopt following technical measures:
Described acrylonitrile butadiene rubber modified polyvinyl chloride salt film is characterized in: polyvinyl chloride salt film comprises UV-531 or 2-hydroxy-4-methyl UVNUL MS-40, and its parts by weight are 0.1-0.6.
Described acrylonitrile butadiene rubber modified polyvinyl chloride salt film is characterized in: thermo-stabilizer is that liquid stabilisers and metallic soap class stablizer are composited.
Described acrylonitrile butadiene rubber modified polyvinyl chloride salt film is characterized in: metallic soap class stablizer barium stearate and Zinic stearas are composited.
Described acrylonitrile butadiene rubber modified polyvinyl chloride salt film is characterized in: liquid stabilisers is a barium cadmium zinc composite stabilizer.
Advantage that the present invention has and positively effect:
Acrylonitrile butadiene rubber modified polyvinyl chloride salt film, owing to adopted brand-new technology scheme of the present invention, compared with prior art, the present invention is with acrylonitrile butadiene rubber modified polyvinyl chloride salt film, consistency is very good during with the PVC blend, and forms a kind of special two phase structure.It is superior that the present invention increases salt film strength, good toughness, sealing property, makes the salt film have the feel of rubber.Acrylonitrile butadiene rubber modified polyvinyl chloride salt film solves the salt membrane product and is prone to the disruptive situation in use, helps environmental protection the work-ing life of effectively improving the salt film, and the good social economic benefit is arranged.
