Abstract
Sterilizing polyester resin includes the following components, by weight, 95 parts of PBT, 5 parts of PET and 0.2-0.4 parts of a composite antibacterial agent which is composed of zeolite powder, nano titanium dioxide, nano silver oxide and polyhexamethylene guanidine phosphate. The antibacterial ABS resin has the following advantages: 1) with the zeolite powder as the carrier for supporting the nano titanium dioxide and the like, the nano titanium dioxide is free of caking, which reduces the effect of photocatalysis; and 2) a titanium dioxide photocatalysis technology and silver ion sterilization are combined for inorganic sterilization, and as well as the polyhexamethylene guanidine phosphate which has strong sterilization effect, so that the sterilization effect is greatly improved due to combination of both inorganic and organic sterilization.
Description
Technical field
The present invention relates to a kind of sterilization polyester resin.
Background technology
In our life, some noxious bacteria is to exist on the top layer of plastic resin goods and breed, the position frequently contacted with human body, object in household electrical appliance, if refrigerator rack, plastic cup cover, door handle, mouse, keyboard, phone housing etc. surface is vegetative place.
The hands of human body contacts with plastic and is infected with germs, and then causes various disease. Along with the user continuous enhancing to health perception, to the demand contacting household electrical appliance plastic components frequently in daily life and proposing " antibacterial, sterilization ".
The development and research of antibiotic plastic started from for the 1980's, makes great progress with Japan, western developed country technology and is widely used in household electric appliances. The development and research of the antibacterial household electrical appliances plastics of China just grew up in recent years, and starting point is low, and achievement is bigger with world standard gap. Household electrical appliances antibiotic plastic has a good application prospect, along with the formal appearance of relative national standards GB21551.2-2010 " particular/special requirement of antibacterial, degerming, the purification function anti-biotic material of domestic and similar applications electrical equipment ", the antibiotic plastic prospect in household electrical appliance market also will be broader.
The core ingredient of antibiotic plastic is antibacterial, and plastic antimicrobial agent is a class novel plastic additive, is broadly divided into inorganic, organic and natural three big series. Organic antibacterial due in safety, thermostability, Durability of antimicrobial effect and broad-spectrum antibacterial property etc. Shortcomings and limit its application; Natural antimicrobial agent toxicity is low, uses safety, but there is poor heat resistance, the shortcomings such as range of application is narrow, Durability of antimicrobial effect is poor.
PBT polyester resin is especially suitable for the manufacture part such as keyboard and mouse, the PBT polyester resin of existing employing inorganic antiseptic, often adopts single antibacterial, or adopts photocatalyst, or adopts silver ion for sterilization, and bactericidal effect is poor.
Summary of the invention
In order to overcome the deficiency of existing PBT polyester resin bactericidal effect difference, the present invention provides the sterilization polyester resin of a kind of composite bactericidal.
This invention address that the technical scheme of its technical problem is: a kind of sterilization polyester resin, including the component of following weight parts: PBT95 part, PET5 part, complex antimicrobials 0.2-0.4 part; Described complex antimicrobials is made up of following component: zeolite powder, nano titanium oxide, nano phase ag_2 o, polyhexamethylene guanidine phosphate.
Described complex antimicrobials, is made up of by weight following component: zeolite powder 21 parts, nano titanium oxide 10 parts, nano phase ag_2 o 15 parts, polyhexamethylene guanidine phosphate 15 parts.
Increasing the performance of polyester resin further, described sterilization polyester resin also includes dispersant 0.3 part, compatilizer 3 parts, and described dispersant is ethylene bis stearamide, and described compatilizer is polypropylene grafted maleic anhydride.
The preparation method of a kind of above-mentioned sterilization polyester resin, comprises the following steps:
A, by zeolite powder, nano titanium oxide mix and blend, under room temperature 90-140 rev/min stirring mixing 3-5 minute, dry.
B, by PBT, PET mix and blend, at 150 DEG C 60-80 rev/min stirring mixing 10 minutes;
C, will through the zeolite powder of a step, nano titanium oxide compound and through b step PBT, PET compound add blender, adding in blender by nano phase ag_2 o, polyhexamethylene guanidine phosphate, the lower 60 revs/min of stirring mixing of blender room temperature make ultimate compound in 20 minutes simultaneously.
D, step c is stirred after ultimate compound add in double screw extruder, the processing temperature of double screw extruder is 290 degree, and engine speed is 320 turns/min, and check rod after extrusion, sterilization polyester resin is made in air-dry pelletizing.
Described step c is also placed with in blender ethylene bis stearamide, polypropylene grafted maleic anhydride.
The present invention is consistent compared with the sterilization polyester resin of technology in use, does not repeat them here.
The beneficial effects of the present invention is: 1, with zeolite powder as carrier, carry the compositions such as titanium dioxide so that titanium dioxide will not harden and reduce photocatalysis effect together. Inorganic sterilization adopts optically catalytic TiO 2 technology and silver ion for sterilization to combine, and also adopts the polyhexamethylene guanidine phosphate of strong bactericidal, and inorganic sterilization and organic bactericide combine, and substantially increase bactericidal effect. 2, polypropylene grafted maleic anhydride is as compatilizer, be not only PET and PBT compatible better, and the zeolite powder being loaded with titanium dioxide can be distributed uniformly be combined in PET and PBT polyester resin, add the comprehensive of sterilization and extend bactericidal effect.
