Description

A kind of damage resistant enhancing PP plastics and preparation method thereof
Technical field
The present invention relates to a kind of plastics and preparation method thereof, more particularly to a kind of damage resistant enhancing PP plastics and its preparation side Method.
Background technology
Polypropylene (Poyropylene, PP) has been widely used in the packaging such as industry, agricultural, medical treatment, health and daily In the every field of life, be that consumption is maximum in current world's high polymer material, a growth rate most fast class product, mainly Because its raw material sources is more, price is low, material property is excellent, electrical insulating property and chemical stability are good, it is easy to add while have again The advantage of work shaping.Although PP advantages are more, also have its not enough, be mainly shown as toughness, low temperature resistant, ageing-resistant performance compared with Difference, and molding shrinkage is big, easy firing, simultaneously because its nonpolar feature, makes itself and other polar polymers, inorganic filler Compatibility it is poor, so as to limit the raw material as products such as injection, fiber, films or the application of PP Pipe Compound.Therefore, in order to Expand PP application field, it is necessary to PP is modified, its performance is improved.
Whether chemically reacted by modification, polyacrylic method of modifying can be divided into physical modification and chemistry changes Property;It can be divided into Blending Toughening Modification, filling enhancing modified, functional modification and flame-retardant modified by using function.Polyacrylic thing Reason is modified main by adding other polymer, filler and compatilizer, and reaching improves the purpose of material property, including blending changes Property, inorganic particulate activeness and quietness is modified and flame-retardant modified etc..Polyolefin blends are studied and application has obtained academia and work The extensive concern of industry and develop rapidly.
The simplest method of polymer modification is the filling-modified of inorganic particulate.By size, inorganic particulate can divide For micro particles, nano-particle and the class of whisker particle three.The filling-modified method of inorganic particulate can not only improve the firm of polymer Degree, hardness, modulus, impact flexibility and heat distortion temperature, moreover it is possible to reduce cost.Due to the intensity and toughness of polymer composites Mainly influenceed, therefore increased using interface with interparticle interface binding intensity by the particle diameter of filler grain, shape and matrix Tough dose or elastomer etc. and the common activeness and quietness PP of inorganic rigid particle, can effectively improve toughness of material, while making material also have There is higher intensity, finally realize PP enhancings and toughness reinforcing.From there through by the fine of inorganic particulate, nanosizing and function of surface Change, filler is changed into functional stuffing, cooperate with the strength and toughness of increase polymer to be filled out as polymer/inorganic with elastomer Expect the study hotspot of composite.
Micro inorganic rigid particles improve PP toughness, can be while its tensile strength and rigidity is not reduced, moreover it is possible to Improve material erosion-resisting characteristics and heat distortion temperature.Nanometer material and technology rises since 1990s, gradually makes inorganic Filler grain develops to nanosizing and functionalization direction.Nano-particles filled polymer must realize that nano-particle exists with polymer It is dispersed on nanoscale, it can be only achieved preferably enhancing, toughening effect.Therefore, using nanometer particle-modified polymer, Appropriate surface treatment should be carried out, the surface energy of particle is reduced, and increases the interface in plasticizing process between particle and matrix Interaction, improves mechanical shear stress, is finally reached the dispersed effect of nano-particle.
Strengthen PP plastics the invention provides a kind of damage resistant, intensity is high, and with excellent scratch resistant performance.
