Description
(1) technical field
The present invention relates to a kind of long-acting broad-spectrum antibiotic polypropylene plastic and preparation method thereof.
(2) background technology
At present, plastics occupy crucial status in daily life and industrial and agricultural production.But the change of Along with people's concept of health recognizes that gradually surface of plastic products can grow all kinds of to the deleterious bacterium of curing the disease of HUMAN HEALTH in a large number.People are for effectively to prevent and kill off and to kill the bacterium that frosting is grown nonparasitically upon another plant, and are employed in usually to add sterilant in the plastics and process antibiotic plastic.Described in Chinese patent 12907719A and the 1687200A etc., nearly all utilize inorganic nanometer powder to carry all kinds of metallicss, as: Ag
+, Cu
2+, Zn
2+But, utilize inorganic antiseptic all need solve the compatibility problem of inorganic nano-particle and plastics, although have much about the nano particle surface modifying method at present, can solve the consistency of inorganic nano-particle and plastics to a certain extent.But in fact the surface treatment of inorganic nano-particle need take a long time and fund, and is difficult to carry out scale operation.And at present general organic antibacterial agent is low owing to decomposition temperature, and the decomposition possibility is big in the course of processing, possibly pollute environment.
(3) summary of the invention:
The objective of the invention is to overcome at present the existing problem of antibiotic plastic in the preparation, invented and utilized a kind of novel preparation of antimicrobial plastics, make plastics have the antibacterial effect of long-acting, broad-spectrum.
To achieve these goals, the present invention adopts following technical scheme:
A kind of long-acting broad-spectrum antibiotic polypropylene plastic, form by the component of following mass parts:
100 parts of Vestolen PP 7052
0.5～5 part of ZPT
0.5～2 part in oxidation inhibitor
1～2 part of dispersion agent.
It is antiseptic-germicide that the present invention adopts ZPT, and being shaped as of described ZPT is granular, and particle diameter is 50nm～2um.
The preferred antioxidant 1010 of described oxidation inhibitor.
Described dispersion agent preferred liquid paraffin.
Comparatively preferred, recommend described antibiotic polypropylene plastic to form by the component of following mass parts:
100 parts of Vestolen PP 7052
1 part of ZPT
1 part of antioxidant 1010
1 part of whiteruss.
The preparation method of long-acting broad-spectrum antibiotic polypropylene plastic of the present invention comprises the steps:
A. the ZPT of 0.5～5 mass parts and the oxidation inhibitor of 0.5～2 mass parts are carried out pre-mixing, obtain the premix material;
B. the premix that step a is obtained mixes with the Vestolen PP 7052 of 100 mass parts, adds the dispersion agent of 1～2 mass parts simultaneously, and fully mixing obtains compound;
C. with the granulation under 180～200 ℃ of temperature condition of the resulting compound of step b, oven dry obtains long-acting broad-spectrum antibiotic polypropylene plastic.
It is that impeller about 3000r/min mixes that said step b adopts rotating speed usually.
Said step c adopts one of following equipment granulation: 1. 2. 3. 4. single screw extrusion machine of Planetary Screw Extruder of parallel double-screw extruder of conical double screw extruder, preferred parallel twin screw extruder.Said prilling temperature is 180～200 ℃, and screw speed is 400r/min.
It is 80～100 ℃ that said step c recommends bake out temperature, and drying time was recommended 12 hours.
Comparatively concrete, recommend the preparation method of long-acting broad-spectrum antibiotic polypropylene plastic according to the invention to carry out according to following steps:
A. the ZPT of 0.5～5 mass parts and the oxidation inhibitor of 0.5～2 mass parts are carried out pre-mixing, obtain the premix material;
B. the premix that step a is obtained mixes with the Vestolen PP 7052 of 100 mass parts, adds the dispersion agent of 1～2 mass parts simultaneously, is abundant mixing in the impeller about 3000r/min at rotating speed, obtains compound;
C. with the resulting compound of step b under 180～200 ℃ of temperature condition, use the parallel double-screw extruder granulation, screw speed is 400r/min, then under 80～100 ℃ of temperature the oven dry 12 hours, obtain long-acting broad-spectrum antibiotic polypropylene plastic.
The polypropylene antibacterial plastics of antibacterial agent ZPT (ZPT) preparation that the present invention adopts are compared with existing antibiotic plastic, have following technique effect:
1, high temperature resistant: because the decomposition temperature of the antiseptic-germicide that adopts greater than 250 ℃, therefore can not decomposed in the course of processing.
2, bacterinertness: all effective under the normal temperature to intestinal bacteria, gold staphylococcus, streptococcus pneumoniae and fungi, have good sterilization and fungistatic effect, and sterilizing rate can reach more than 99%.
3, surface property: smooth finish is good, and surfacing is smooth.
4, mechanical property: mechanical property has a large amount of raisings with respect to pure Vestolen PP 7052.
5, resistance to deterioration: the color and the mechanical property of aging 21 days antibiotic plastics do not descend under ultraviolet light conditions.
6, security: nontoxic, tasteless, as to meet relative national standards and European Union ROSH instruction.
7, simple to operation, less demanding to mechanical means is suitable for large, medium and small various enterprise.
8, with low cost, have good economic benefit.
