Embodiment Construction

[0006] The invention adds nano-scale inorganic antibacterial agent to polyethylene terephthalate (PET). Inorganic nano antibacterial agent is the method of physical adsorption and ion exchange, which will have antibacterial Ag + 、cu 2+ 、zn 2+ Plasma and its compounds are obtained by adsorbing in loose and porous carrier materials such as zeolite, silica gel, and bentonite. It has the advantages of high temperature resistance, not easy to decompose, safe and hygienic, and long-lasting functions.

[0007] At present, the most commonly used method for manufacturing inorganic nano-antibacterial agents is to use hydrated silicates of alkali metals or alkaline earth metals as carriers. It is a structure in which silicon, aluminum, and oxygen tetrahedrons connected by oxygen bridges are arranged infinitely in the form of a skeleton in a three-dimensional space. In a 4-hedron. The 1 negative valence to which the aluminum is attached is balanced by an exchangeable cation. The oxy...

Abstract

The present invention discloses a method for making antibacterial drinking water urn. Said method includes the following steps: firstly, making high-concentrated antibacterial PET mother granules: uniformly mixing PET, nano-grade inorganic antibacterial agent and adjuvant in high-speed mixing machine; then placing the above-mentioned mixture into twin screw extruder machine, in the temperature range of 250-280deg.C melting and making high-concentrated antibacterial PET mother granules; then mixing the obtained high-concentrated antibacterial PET mother granules and PET raw material according to a certain ratio, drying for 4hr. at 150deg.C in air blast drying machine, adding the above-mentioned material into injection-moulding machine and forming to obtain drinking water urn bottle blank, then placing said drinking water urn bottle blank into bottle-blowing machine to make blowing so as to obtain the invented antibacterial drinking water urn.

Description

Technical field: [0001] The invention relates to a drinking water bucket, in particular to a method for manufacturing a drinking water bucket with antibacterial function. Background technique: [0002] In recent years, with the continuous improvement of people's living standards, water dispensers have become popular. After the water dispenser has been used for a period of time, it is inevitable that bacteria in the air and bacteria brought by the user will be mixed into the bucket, and the water in the drinking bucket will pass through the water dispenser. The bacteria in the outflow water seriously exceed the standard, forming the problem of secondary pollution of the water dispenser. At present, drinking water barrels are generally ordinary plastic products without antibacterial function. Invention content: [0003] Aiming at the shortcomings of the prior art, the present invention provides a nano antibacterial drinking bucket, which can effectively inhibit common bacte...
