Abstract
Antibacterial ABS resin includes, by weight, 100 parts of ABS and 0.2-0.4 parts of a composite antibacterial agent which is composed of the following components: zeolite powder, nano titanium dioxide, nano silver oxide and polyhexamethylene guanidine phosphate. The antibacterial ABS resin has the following advantages: 1) 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; and 2) 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.
Description
Technical field
The present invention relates to a kind of antibacterial ABS 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.
The ABS plastic material of existing employing inorganic antiseptic, often adopts single antibacterial, or adopts photocatalyst, or adopt silver ion for sterilization, and bactericidal effect is poor.
Summary of the invention
In order to overcome the deficiency of existing Antibacterial ABS plastic bactericidal effect difference, the present invention provides the antibacterial ABS resin of a kind of composite bactericidal.
This invention address that the technical scheme of its technical problem is: a kind of antibacterial ABS resin, including the component of following weight parts: ABS100 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 13 parts, nano titanium oxide 10 parts, nano phase ag_2 o 10 parts, polyhexamethylene guanidine phosphate 15 parts.
Also including dispersant 0.6 part, described dispersant is ethylene bis stearamide.
The preparation method of a kind of above-mentioned antibacterial ABS 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, adding blender through the zeolite powder of a step, nano titanium oxide compound and ABS, and nano phase ag_2 o, polyhexamethylene guanidine phosphate be added in blender simultaneously, the lower 60 revs/min of stirring mixing of blender room temperature make ultimate compound in 20 minutes.
C, b step is stirred after ultimate compound add in double screw extruder, the processing temperature of double screw extruder is 200 degree, and engine speed is 320 turns/min, and check rod after extrusion, antibacterial ABS resin is made in air-dry pelletizing.
Increase a diffusant, described b step is also placed with in blender ethylene bis stearamide.
The present invention is consistent with ABS plastic in use, does not repeat them here.
The beneficial effects of the present invention is: 1, 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, with zeolite powder as carrier, the compositions such as titanium dioxide are carried so that titanium dioxide will not harden and reduce photocatalysis effect together.
