Description
Technical field
The invention belongs to chemical material field, particularly controlled PP film of the high temperature resistant ageing-resistant degraded of one and preparation method thereof.
Background technology
Polypropylene (PP) is the polymkeric substance of a kind of nontoxic, odorless, tasteless oyster white height crystallization, is one of kind the lightest in current all plastics.It is stable especially to water, and the water-intake rate in water is only 0.01%, and molecular weight is about 8-15 ten thousand.Good moldability, but because of shrinking percentage large (for 1%-2.5%), thick article easily caves in, and to the higher part of some dimensional precisioies, is difficult to reach requirement, product surface good luster, is easy to painted.
Polyacrylic degree of crystallinity is high, compound with regular structure, thus has excellent mechanical property.The absolute value of Mechanical Properties of PP higher than polyethylene, but still belongs to kind on the low side in a plastic material, and its tensile strength only can reach 30MPa or slightly high level.The polypropylene that isotactic index is larger has higher tensile strength, but with the raising of isotactic index, the shock strength of material declines to some extent, but no longer changes after dropping to a certain numerical value.Temperature and loading rate very large to polyacrylic Toughness.When temperature is higher than second-order transition temperature, impact fracture is ductile rupture, be brittle rupture, and impact value significantly declines lower than second-order transition temperature.Improve loading rate, the temperature that ductile rupture can be made to change to brittle rupture rises.Polypropylene has excellent flexural fatigue resistance, its goods bent 106 times and do not damage at normal temperatures.But under room temperature and low temperature, because the molecular structure regularity of itself is high, so resistance to impact shock is poor.The most outstanding performance of polypropylene is exactly flexural fatigue resistance, is commonly called as polypropylene (PP).Polypropylene has good thermotolerance, and goods temperature to carry out disinfection sterilizing more than 100 DEG C, and not by under the condition of external force, 150 DEG C also indeformable.
Polyacrylic chemical stability is fine, outside decapacitation is corroded by the vitriol oil, concentrated nitric acid, all more stable to other various chemical reagent, but low-molecular-weight aliphatic hydrocarbon, aromatic hydrocarbon and chlorinated hydrocarbon etc. can make polypropylene softening and swelling, simultaneously its chemical stability also increases with the increase of degree of crystallinity, so polypropylene is applicable to making various chemical pipeline and accessory, anticorrosion ability is good.
Due to the physical and chemical performance that polypropylene is good, it is applied in every field, PP film have also been obtained as a kind of membranous type material and applies widely, but because when PP film uses in the environment, degradability is poor, therefore the feature of environmental protection for life-time service brings impact, therefore needs the environmental problem that a kind of PP membranous type material that can degrade of exploitation comes to avoid it due to degradation property difference band.
Application number be 201210168707.4 Chinese patent disclose a kind of Thermal oxidative degradation polypropylene sheet, comprise the sheet material become by extrusion processing by mixing material, this Thermal oxidative degradation polypropylene sheet complete processing is simple, energy is degraded, cost is lower, and color and luster and feel better, not only inexpensive, and reach the object of environmental protection and energy saving.Application number is that the Chinese patent of 200410065645.X discloses a kind of nontoxic, fire-retardant, degradable PP decorative film and preparation method thereof, may be used for surface such as laminating metal sheet, plank etc. and plays decoration function.Although but disclose degradable PP film in above prior art, but its degradation property is general, its degradable condition used and time can not be controlled, bring inconvenience to actual use, its PP film does not carry out the further improvement of resistance to elevated temperatures yet simultaneously, therefore also has some limitations in application aspect.
