Embodiment Construction

[0024] see figure 2 As shown in the process flow chart of the anti-mite PE light-duty conveyor belt of the present invention, a method for manufacturing an anti-mite polyethylene light-duty conveyor belt, wherein the light-duty conveyor belt is made of anti-mite treated polyester fabric and anti-mite modified It is made of composite polyethylene material, and the manufacturing method includes the following steps:

[0025] The first step: the anti-mite agent (the active ingredient is isothiazolinone compounds, that is, 5-chloro-2-methyl-4-isothiazolin-3-one / 2-methyl-4-isothiazoline- 3-ketone, RHZL-03 provided by Shanghai Runhe Nano Technology Co., Ltd.) Add water to make an anti-mite treatment solution with a concentration of 50-100g / L;

[0026] Step 2: Immerse the polyester fabric in the anti-mite treatment liquid in the first step, the impregnation amount is 150-200g / m 2 , drying and characterization by far-infrared heating, the drying temperature is 80-90 ° C, and the ant...

Abstract

The invention relates to a manufacturing method for a mite-proof polyethylene light conveyer belt. The method sequentially comprises the following steps of: adding water into a mite-proof agent to prepare mite-proof treatment solution; soaking a polyester fabric into the mite-proof treatment solution, drying and determining the nature to prepare a mite-proof treated polyester fabric; crushing polyethylene granules, sieving, mixing the powder and the mite-proof agent, and blending and granulating the mixture through a double-screw extruder to prepare mite-proof modified polyethylene (PE) granules, wherein the mass content of the mite-proof agent is 2 to 5 percent; and compounding the mite-proof modified PE material and the mite-proof treated polyester fabric by using an extrusion calendering process, keeping the extrusion temperature at 130 to 150 DEG C, and keeping the surface temperature of the mite-proof treated polyester fabric at 120 to 150 DEG C; and cooling the conveyer belt to room temperature. The invention has the advantages that: the mite-proof agent can kill mites and inhibit reproduction of the mites, has no harm to the human body, and has high chemical stability and thermal stability; the mite-proof agent has good compatibility with PE, and does not influence the machining property and other mechanical properties of the PE light conveyer belt; and the method totally accords with the food hygienic standard of American FDA and the laws and regulations of European Union REACH.

Description

technical field [0001] The invention relates to the field of manufacturing light-duty conveyor belts, in particular to a method for manufacturing a mite-proof polyethylene light-duty conveyor belt. Background technique [0002] PE light-duty conveyor belts generally use polyester fabric as the skeleton material, and are mainly used to transport light and medium-quality items. PE light conveyor belt is widely used in food processing, tobacco and other industries due to its advantages of light weight, long life, convenient installation, and less friction. However, mites are prone to be produced during the processing of tobacco products, and the surface of the PE light conveyor belt is contaminated with mites, which will multiply and expand rapidly, bringing harm to the quality of tobacco products and people's health. [0003] Therefore, on the basis of satisfying the physical and mechanical properties of PE light-duty conveyor belts, endowing PE light-duty conveyor belts with...
