Above examples of implementation can be according to practical situation, under the prerequisite that does not reduce the performance pointer, select for use 6000 order inorganic material powders of different additions to reach the purpose that reduces production costs, can save 5%～15% cost according to the different additions and the product comparison of corresponding common fillers.
The made product of embodiment is detected by Tianjin quality monitoring testing station the 5th station, reaches corresponding national standards fully.
Select for use 6000 order inorganic material powders with inorganic rigid particle strengthen, toughness reinforcing theory is as the research theory foundation.
In the physically modified of PVC, properties-correcting agent is distinguished flexible body and inelastic body two classes by amount of rigidity.Though can obtain comparatively ideal toughness with elastomeric method, increase the loading level of cheap properties-correcting agent, reduced intensity, rigidity, thermotolerance and the processing fluidity of material, be to be that cost reaches the purpose that reduces cost to sacrifice certain mechanical property.But not elastic body toughening then is a kind of newer method, especially developed recently " inorganic rigid particle strengthens, toughness reinforcing theory " that get up, not only can improve toughness, rigidity, the increase size stability of PVC, but also can make intensity, modulus, heat-drawn wire, processing fluidity obtain suitable improvement.
This theory general solution is interpreted as: inorganic particulate is dispersed in the matrix resin, and when being subjected to external impacts, because the existence of inorganic particulate has produced stress concentration effect, resin produces crack splitting around causing.Simultaneously, the matrix between the particle has also produced viscous deformation, absorbs striking energy, thereby reaches toughening effect; The existence of inorganic particulate is obstructed and passivation the matrix cracking expansion, finally stops the unlikely destructiveness cracking that develops into of tiny crack; Along with the particle fineness attenuates, the specific surface area of particle increases, and particle and matrix contact area increase, and material can produce more crack crackle and viscous deformation when being hit, thereby absorbs energy.Another kind of mechanism is thought two tensile stresss very that act on of matrix and particle, and the position is a stress under the line.Because the effect of power, effect can be stressed near the equator of particle, helping surrender occurs, in addition, because the two poles of the earth are subjected to action of pulling stress, when the interface cementability is more weak, the interface unsticking can at first take place at the two poles of the earth, form a hole around being equivalent to make particle, according to the stress distribution for the hole, the stress on the equatorial plane of hole is 3 times of this body stress.Therefore, when this body stress did not reach the matrix yielding stress as yet, partial points had begun to produce surrender, promptly equally also impelled the matrix surrender, and combined effect improves the toughness of superpolymer.
By to different-grain diameter CaCO
3With discovering of PVC compound system performance: under the situation that inorganic rigid particle is not reunited, the more little resulting composite property of particle diameter is good more, especially adds an amount of nanometer CaCO in the co-mixing system
3During particle, its shock strength, tensile strength and elongation at break all can be improved simultaneously.Chemical process modified Nano CaCO
3, its interaction between homodisperse and interface in the PVC matrix is strengthened, thereby cause its shock strength, elongation at break, tensile modulus all to increase considerably, and tensile strength almost remains unchanged; But, work as CaCO
3Consumption surpasses at 15% o'clock, nano level CaCO
3The matrix material of modification all is lower than by micron order CaCO on tensile strength and notched Izod impact strength
3The composite system of modification.By analysis, particle diameter is thin more, the phenomenon of powder generation secondary agglomeration is serious more, though the particle diameter of addition material is thin more in theory, add the enhancing that obtains in the polymkeric substance to, toughness reinforcing mechanical property is outstanding more, because the as easy as rolling off a log generation secondary agglomeration of nano-powder, the true particle diameter of nano-powder is often much larger than theoretical particle diameter during application but in fact.May command still under laboratory environment, in case be amplified to interim test, the quality of product not only can not improve and occurs the phenomenon that descends on the contrary.Therefore, the 6000 order inorganic material powders that the present invention uses, its particle diameter of 90%≤2 μ m (can be expressed as D
90≤ 2 μ m), both had the advantage of part nano-powder, solved the shortcoming of nano-powder " easily reunion, the difficult dispersion " again substantially.
