Problems solved by technology

Although paper garbage bags and paper-plastic composite bags are environmentally friendly due to their materials, they are far inferior to plastic garbage bags in terms of mechanical strength and durability.
However, the airtightness of the material that plastic waste is easy to cause will easily lead to the growth of bacteria

preparation example Construction

[0010] The invention provides a kind of preparation method of high-strength antibacterial garbage bag, comprising:

[0011] First polycarbonate resin, phenolic resin, aluminum stearate, kaolin, calcium silicate, attapulgite, chitin fiber, turpentine, vinyl trimethoxysilane, dioctyl phthalate and brand KH560 The silane coupling agent is mixed and rubberized to obtain a rubber compound; then, the rubber compound is added to an extruder for extrusion molding and processing to obtain a high-strength antibacterial garbage bag;

[0012] Wherein, the extruder includes a feeding section, a middle section and an extruder head connected in sequence, and the working temperature of the extruder is: feeding section 90-100°C, middle section 110-125°C, extruder head 150°C -195°C.

[0013] In the above technical solution, the conditions of the rubber mix can be selected in a wide range, but in order to further improve the tensile strength and tensile properties of the garbage bag made, prefe...

Abstract

The invention discloses a high-strength antibacterial garbage bag and a manufacture method thereof. The manufacture method comprises the steps of firstly carrying out mixing and rubber mixing on polycarbonate resin, phenolic resin, aluminum stearate, kaolin, calcium silicate, attapulgite, chitosan fiber, turpentine, vinyl trimethoxy silane, dioctyl phthalate and a silane coupling agent of which the mark is KH560 to prepare a sizing material; adding the sizing material to an extruder for extrusion molding and processing to prepare the high-strength antibacterial garbage bag, wherein the extruder comprises a feeding section, a medium section and an extrusion head which are sequentially connected; and the operating temperatures of the extruder are as follows: the operating temperature of the feeding section is 90-100 DEG C, the operating temperature of the medium section is 110-125 DEG C and the operating temperature of the extrusion head is 150-195 DEG C. The high-strength antibacterial garbage bag has excellent mechanical properties, such as high tensile strength and good tensile property, and also has excellent antibacterial property.

Description

technical field [0001] The invention relates to the field of garbage bags, in particular to a high-strength antibacterial garbage bag and a preparation method thereof. Background technique [0002] Garbage bags, as the name suggests, are bags for garbage. A small bag brings great convenience to thousands of households, and it also provides an important guarantee for environmental protection, and is even conducive to garbage recycling and classification. According to the classification of materials, garbage bags can be divided into plastic garbage bags, paper garbage bags and paper-plastic composite bags. Although paper garbage bags and paper-plastic composite bags are environmentally friendly due to their materials, they are far inferior to plastic garbage bags in terms of mechanical strength and durability. However, the airtightness of the material that plastic waste is easy to cause will easily lead to the growth of bacteria. Contents of the invention [0003] The purp...
