The hard PVC plastic comprises the following components in parts by weight: 30-80 parts of PVC, 3-6 parts of plasticizer, 10-20 parts of thermal stabilizer, 3-20 parts of antioxidant, 1-10 parts of rutile type titanium dioxide, 1-2 parts of lubricating agent, 10-20 parts of filler and 1-20 parts of foaming agent. The hard PVC plastic is high in plasticization speed, high in mechanical strength, difficult to change colour, deform or crack, better in electrical insulation property, high in light fastness and heat resistance and good in stability performance.
Description
Technical field
The present invention relates to the plastic cement field, relate in particular to a kind of hard PVC.
Background technology
Igelite is as main raw material take polyvinyl chloride resin, be aided with the additives such as stablizer, softening agent, lubricant, weighting agent, combine through scientific formula, molded under certain temperature and pressure, cooling curing becomes specified shape PVC plastics.Difference soft, hard that the PVC goods have.Generally speaking, the consumption of softening agent represents the mass fraction of the required formulation material of per 100 mass parts resins at 10PHR(PerHundredResin in the prescription) following PVC goods are called hard product; The consumption of softening agent is called the semi-rigid goods at the PVC of 10～40PHR goods; The PVC goods that the consumption of softening agent surpasses 40PHR are called flexible article.In order to improve the melt-processible of PVC, PVC prescription melt-moldable processibility should be added processing aid in the PVC prescription.Facts have proved, for the hard PVC goods, do not have processing aid can not melt molding processing, and for flexible PVC matter product, do not have or be short of processing aid, also be very difficult moulding.The processing aid of PVC mainly is the acrylate resin (ACR) that excellent compatibility is arranged with PVC, and chlorinatedpolyethylene (CPE), chlorosulfonated polyethylene, vinyl toluene polymkeric substance, MBS, ABS etc.Rigid plastics is used very extensive, can be used for tubing, toy etc.
Summary of the invention
The invention provides a kind of hard PVC, physical strength is high, toxicity is low.
The present invention is by the following technical solutions:
A kind of hard PVC comprises the component of following weight part meter:
Polyvinyl chloride 30-80 part,
Softening agent 3-6 part,
Thermo-stabilizer 10-20 part,
3～20 parts of antioxidants,
1～10 part of Rutile type Titanium Dioxide,
1～2 part of lubricant,
10～20 parts of stopping composition,
1～20 part of whipping agent,
1～2 part on mica,
0.3～0.8 part of sodium dodecyl,
10～15 parts of stearic acid,
3～4 parts of vinyltriethoxysilanes,
N, 8～20 parts of N-ethyl perfluor dodecanoyl amido propylene diamine.
Polyvinyl chloride is the loose type resin, its tissue looseness, and surface shape is irregular, and section is loose porous to be netted, therefore, can absorb fast softening agent, and plasticizing rate is fast.
The purpose that adds softening agent is that the macromolecular chain mobility is increased, and makes molecular assembly generation crystallite effect, improves the physical strength of hard PVC.In order to make physical strength reach the highest, produce the antiplasticization phenomenon, the deal of adding is selected 3-6 part.
The preferred straight chain ester plasticizer of softening agent or epoxy plasticiser or the mixing of the two.The preferred 1:1 of the weight ratio of straight chain ester plasticizer and epoxy plasticiser.As a kind of preferred, the straight chain ester plasticizer is the DOS(2-ethylhexyl), bad with the PVC consistency because it belongs to cold resistant plasticizer, so deal is selected the 3-4 weight part.
PVC at high temperature processes, and very easily emits HCL, forms unsettled polyene structure, and simultaneously, HCL has self-catalysis, and PVC is further degraded.Various bad phenomenon will appear in plastics, and such as variable color, distortion, be full of cracks, physical strength decline, electrical insulation capability decline, embrittlement etc., adding thermo-stabilizer can solve the problems of the technologies described above.
The characteristics such as prior art adopts lead salt stabilizer usually, and it has, and thermo-stabilizer is good, electrical property is excellent, and is inexpensive, but its toxicity is larger, easily pollutes goods.Be organic tin thermo-stabilizer and the epoxies stablizer of 3:1 in order to reduce or to make nontoxicity, thermo-stabilizer preferably select weight ratio.Organic tin thermo-stabilizer better performances adds the epoxies stablizer therein as auxiliary stabilizer, and the time spent can be improved the stability of light and heat.The effect that adds antioxidant be for make the PVC goods in the processing use procedure, avoid because of be heated, ultraviolet effect generation oxidation.The preferred dihydroxyphenyl propane of antioxidant, it is combined with radical, forms stable compound, and chain reaction is stopped.
The purpose that adds Rutile type Titanium Dioxide is in order to improve the weathering resistance of hard PVC.
The excessive meeting of lubricant causes the hard PVC strength decreased, also affects technological operation, and 1～2 part the most suitable.The preferred stearic acid of lubricant and paraffin.The two weight ratio is 1:1.
As preferably, stopping composition is calcium carbonate or barium sulfate.
As preferably, whipping agent is a kind of in ADC whipping agent or Diisopropyl azodicarboxylate or lead salt or the cadmium salt.
The preparation method of above-mentioned hard PVC: polyvinyl chloride (PVC) RESINS and other each components are mixed first, after the preheating, place in the open die cavity again, impose behind the mold closing heat and pressure (Heating temperature is 200-300 ℃., pressure is 20-30Mjpa), until till the hardened material.
Hard PVC apparent density of the present invention is 0.53-0.55g/ml, about viscosity number 85ml/g, volatile matter (comprising water) content is lower than 0.4%, volatile content well below national Specification, residual vinyl chloride content is below 1.5ppm, and toxicity is low, physical strength is high, be difficult for color-changeable shape-changeable or be full of cracks, fast light good heat resistance, stability are good.
