Description
Technical field
The invention belongs to modified plastics technical field, and in particular to a kind of ageing-resistant modified poly ethylene plastics.
Background technology
Polyethylene abbreviation PE, is one of five big synthetic resin, polyethylene is broadly divided into LLDPE, low-density
Polyethylene, high low density polyethylene (LDPE) three major types, polyethylene odorless are nontoxic, and feel ceraceous is minimum to make with excellent resistance to low temperature
- 70 DEG C are can reach with temperature, chemical stability is good, but polyethylene is very sensitive to environmental stress, and heat-resistant aging is poor.
The content of the invention
The purpose of the present invention is that there is provided a kind of ageing-resistant modified poly ethylene plastics the problem of being directed to existing.
The present invention is achieved by the following technical solutions：
A kind of ageing-resistant modified poly ethylene plastics, are made up of following component by weight：Polyvinyl resin 70-80, titanium dioxide
3-5, calcium carbonate 15-20, talcum powder 3-6, organic siliconresin 10-12, polyphenylene phosphonic acids diphenyl sulphone (DPS) ester 4-6, nanometer sericite 1-
3rd, rosin/butyl rubber crosslinked blends 8-10, plasticizer 1-3.
Further, the polyvinyl resin is LLDPE.
Further, the calcium carbonate is powdered whiting.
Further, the titanium white Powder Particle Size is 1250 mesh.
Further, the rosin/butyl rubber crosslinked blends preparation method is：Rosin, butyl rubber are passed through respectively
110 DEG C of dryings 2 hours, then by 5:2 mass ratios are uniformly mixed, then add the vinyl triethoxyl silicon of rosin quality 5%
The potassium peroxydisulfate of alkane, polyethylene quality 0.15%, then after 5min is blended under 3000r/min rotating speeds in high mixer, through double spiral shells
Bar extruder is granulated, and is produced.
Further, the plasticizer is epoxidized soybean oil.
Further, the organic siliconresin is dimethyldichlorosilane.
The ageing-resistant modified poly ethylene plastics preparation method is：By weight by each raw material in super mixer, its
Middle rosin/butyl rubber crosslinked blends are finally added, and then mix 10-15min, then be placed in double screw extruder through melting
Extrusion, cooling, pelletizing, packed products；Wherein, the area's temperature of double screw extruder one is 80 DEG C, and 2nd area are 150 DEG C, 3rd area
For 190 DEG C, 4th area are 200 DEG C；5th area are 200 DEG C, and the residence time is 3min, and pressure is 12Mpa.
The present invention has advantages below compared with prior art：The present invention, can by adding a certain amount of nanometer of sericite
The effective mechanical property for improving modified plastics, meanwhile, the function of its certain shielding ultraviolet rays having can effectively weaken
The degree of aging of nano composite material, meanwhile, the present invention by add prepare rosin/butyl rubber crosslinked blends, its
There is good dispersiveness in vinyon system, reunite less, it is possible to increase the combination property of vinyon, meanwhile,
A part of rosin/butyl rubber crosslinked blends are combined with nanometer sericite particle, can effectively improve a nanometer sericite
Ultraviolet shielding effect, so as to improve the ageing-resistant performance of polyethylene, most rosin/butyl rubber crosslinked blends are more
Many is combined with polyethylene molecule, forms stable three-dimensional network cross-linked network, can effectively play a part of crosslinking points,
The significant heat resistance for improving vinyon, and heat decomposition temperature, meanwhile, effectively raise between polyethylene molecule
Bond energy, higher external world effect can be resisted, the ageing-resistant performance of vinyon is improved so as to reach, together
When, rosin/butyl rubber crosslinked blends can be combined to form resistance to oil reservoir on vinyon top layer, can effectively reduce
The lipophile of vinyon.
