Method for detecting volatile components in water-based glue for cigarette

Abstract

The invention provides a method for detecting volatile components in a water-based glue for cigarette. The method concretely comprises the following steps: weighing M1 g of a water-based glue sample,performing membrane filtration on the water-based glue by an ultrafilter membrane, cleaning the ultrafilter membrane with M2 g of anhydrous ethanol or DMF, collecting the obtained filtrate and cleaning solution to obtain a solution to be detected, taking and injecting 1 mL of the solution to be detected into a chromatographic bottle, analyzing the solution to be detected through a gas chromatograph-mass spectrometer to obtain data of various detected components in the sample to be detected, calculating the content W2 of all the detected components in the sample to be detected according to a standard curve, and multiplying the content W2 by a corresponding dilution ratio (M1 + M2) / M1 to obtain the content W1 of all the detected components in the original water-based glue sample, wherein 3M1< M2 < 5M1. The method can be used for detecting various volatile substances in the water-based glue, can provide the quantification information of volatile chemical components affecting the sensoryquality of the cigarette in the water-based glue sample, and has good practical values.

Description

technical field [0001] The invention relates to a chromatographic detection method through the separation and quantitative analysis of the volatile components of the water-based glue of the cigarette tipping paper ink raw material, including headspace-mass chromatography and ion chromatography. Background technique [0002] Adhesives are additives made of film-forming materials that can be dispersed or dissolved in water. Film-forming materials are generally organic polymers, animal glue, starch, dextrin, serum albumin, albumin, methylcellulose and polyvinyl alcohol are all such adhesives, and there are some soluble intermediates of phenolic and urea-formaldehyde resins. bodies also fall into this category. Some adhesive film-forming materials can be dissolved or dispersed in water by means of alkaline solution. Examples of this type include casein, rosin, shellac, carboxyl-containing vinyl acetate or acrylate copolymers (such as crotonic acid, methyl acrylic acid or malei...

AI Technical Summary

Problems solved by technology

The main disadvantages include: curing requires an oven (or possible renovation of existing ovens), takes up more plant space, and may increase plant energy consumption; more wastewater and sludge are generated; more stringent production and operation requirements ; It is still difficult for water-based adhesives to completely replace solvent-based adhesives

In addition, in order to improve the applicability and other properties of water-based adhesives, a variety of additives will be added, which are not covered by conventional testing methods and product standards
