Description
Technical field
The present invention relates to a kind of preparation method of nano-titanium dioxide modified engineering plastics, belong to modified engineered plastic technology
Field.
Background technology
Engineering plastics refer to tensile strength in more than 50MPa, bending modulus in more than 2GPa, impact strength 60J/m with
On, long-term use temperature more than 100 degrees Celsius, for the plastics of the industries such as automobile, machinery, electronic apparatus.
Modified engineered plastic, refers on the basis of general-purpose plastics and engineering plastics, by sides such as filling, blending, enhancings
Method is processed, and improves the plastic products of the performance of the aspects such as anti-flammability, intensity, impact resistance, toughness.Common plastics are often
The characteristic and defect of its own are had, modified plastics is exactly to change property to plastics, and basic technology includes：1st, strengthen：
By glass fibre etc. and plastic blend increasing the mechanical strength of plastics.2nd, fill：By the fillers such as mineral and plastic blend, make
The properties such as shrinkage factor, hardness, the intensity of plastics are changed.3rd, toughness reinforcing：Toughener is added to be blended to carry by common plasticses
The toughness of plastics high, the product after toughening modifying：Rail pad.4th, it is fire-retardant：Common plasticses resin the inside addition fire retardant is given, i.e.,
Plastics can be made has flame-retarding characteristic, and fire retardant can be the compound system of a kind of or several fire retardants, such as bromine+antimony system, phosphorus
System, nitrogen system, silicon systems, and other inorganic fire-retarded systems.5th, resist cold：Increase plastics intensity and toughness at low temperature, general modeling
Material black brittleness intrinsic at low temperature so that change, it is necessary to add some low temperature resistant toughener using limited in low temperature environment
Become the plastics such as plastics fragility at low temperature, such as bumper, it is general to require to resist cold.
Engineering plastics are sometimes also required to antibacterial functions using in extensive range.
The content of the invention
The purpose of the present invention is to make up the deficiencies in the prior art part, there is provided a kind of nano-titanium dioxide modified engineering plastics
Preparation method.
The preparation method of nano-titanium dioxide modified engineering plastics of the invention, with nano titanium oxide, polypropylene, crosslinking
Agent, toughener, filler, reinforcing agent, age resister, dispersant and stabilizer are raw material, are comprised the following steps：
1）Proportionally weigh appropriate raw material；
2）By nano titanium oxide, polypropylene, crosslinking agent, toughener, filler, reinforcing agent, age resister, dispersant and stabilization
Agent is kneaded in mill, obtains nano-titanium dioxide modified engineering plastics.
Preferably,
Described step 2）In, in mixing process, it is additionally added accelerator and age resistor.
Described step 2）Afterwards, also including slitting or granulation step.
The present invention has the following technical effect that：Nano-titanium dioxide modified engineering plastics prepared by the present invention, with preferable
Anti-microbial property.
