Abstract

The invention discloses a low-foam neutral water-based chain plate lubricant and a preparation method thereof. The low-foam neutral water-based chain plate lubricant is composed of the following raw materials in percentage by mass: 0-5% of fatty acids; 0.5-5% of fatty alcohol ether, 1-10% of fatty alcohol polyoxyethylene ether, 0.5-5% of organic phosphonate, 0.1-0.5% of defoaming agent, 0.1-1% offungicide, and the balance of water. The invention also discloses a preparation method of the low-foam neutral water-based chain plate lubricant. The lubricant of the invention takes the mixture obtained by mixing fatty acids, fatty alcohol ethers and fatty alcohol polyoxyethylene ethers as lubricating components, and the mixture has the characteristics of good lubricating effect and low foamability. The water-based chain plate lubricant of the invention does not generate a large amount of foam in use, does not cause corrosion to the production equipment, and has high hard water resistance andexcellent bacteriostasis ability, and can effectively reduce the bottle falling-down rate of the conveying facilities, reduce the occurrence of the springboard phenomenon, thereby achieving the purpose of improving the production efficiency of the workshop.

Description

technical field

[0001] The invention relates to a lubricant, in particular to a low-foaming neutral water-based chain plate lubricant and a preparation method thereof. Background technique

[0002] Water-based chain plate lubricant is an environmentally friendly lubricant for lubricating and cleaning automatic conveyor belts in beverage production, filling and sealing processes. In the process of product conveying, if the sliding friction coefficient of the contact surface between the conveying chain plate and the packaging container is too large, the packaging containers will be squeezed against each other, resulting in blockage, bottle inversion, etc., as a result, the efficiency of the conveying device is reduced, and production personnel are required. Problems can be solved manually and normal production can be resumed. The sliding friction coefficient of the contact surface between the conveyor chain and the packaging container will continue to increase with the accumu...

Examples

Embodiment 1

[0043] 1. Preparation of water-based chain plate lubricant

[0044] (1) Take 10g of cis-9-octadecenoic acid, 50g of isodecacarbonyl alcohol polyoxyethylene ether, 10g of dipropylene glycol methyl ether, 30g of ethylenediaminetetramethylenephosphonate sodium, respectively, and 200g of pure water will The above substances are evenly dispersed;

[0045] (2) add 5g bactericide and 3g defoamer wherein, stir;
