Technical Field
The invention relates to the technical field of ignition rod preparation, in particular to an ignition rod for a smoking agent and a manufacturing method thereof.
Background
The smoke pesticide is also called fumigant and smoke agent, and is a pesticide formulation which is widely popularized and used in vegetable production areas. The smoke pesticide is prepared with pesticide, heat generating agent, combustion promoter, dispersant and other components and through special technological process. The smoke pesticide has two preparations of powder and pastille. It acts on the affected plants by burning to produce smoke. The ignition wire is an important tool for igniting the smoke agent, and the traditional process determined after years of practice is to use the ignition wire for igniting the smoke agent. Among the technical requirements for use approved by the original Ministry of agriculture, there is a clear description of "after ignition of a powder twist (ignition wire), insertion of the powder, ignition of the powder, and then sealing of the housing". The national regulations on the safety management of fireworks and crackers stipulate that black powder, pyrotechnic powder and firing cable cannot be sold to any unit or individual who does not obtain the safety production license of fireworks and crackers. As the use of the smoke agent firing cable by pesticide production enterprises is not suitable for managing fireworks and crackers, the safe production license of the fireworks and crackers cannot be obtained, and the purchase and use of the firing cable are in the grey zone for a long time. In addition, in the storage process of the ignition wire, due to environmental factors, the ignition is difficult due to the fact that the ignition wire is often affected with damp, and therefore, the preparation of the safe and efficient ignition substance becomes a hotspot of research of people.

And (4) relevant performance test:
1. hydrophilicity and hydrophobicity test
Deionized water was used as a test medium, contact angles between the igniter stick samples prepared in examples 1 to 3 and comparative examples 1 to 2 and the deionized water were measured by a liquid drop method, and three parallel samples were selected for each group of samples to reduce experimental errors, and the results are shown in table 1.
TABLE 1
Example 1 Example 2 Example 3 Comparative example 1 Comparative example 2
Contact angle 130° 125° 122° 65° 85°
As can be seen from Table 1, the ignition stick prepared in the example 1-3 has good hydrophobic property, the hydrophobic property of the comparative example 2 is poorer than that of the example 1-3, and the comparative example 1 has certain hydrophilicity, so that when the environment is humid, the ignition stick prepared in the comparative example 1 easily absorbs the moisture in the environment, and the ignition effect is influenced.
2. Moisture resistance test
Sample treatment: the samples prepared in examples 1 to 3 and comparative examples 1 to 2 were placed in a closed container having an air humidity of 85% and left at room temperature for 30 days.
The samples prepared in each example and comparative example were taken, 20 samples each without and with the above treatment were subjected to the ignition test, and the test data are shown in table 2.
TABLE 2
Object Untreated samples Treated samples Strength of treated sample
Example 1 Ignition at 100% Ignition at 100% No abnormality
Example 2 Ignition at 100% Ignition at 100% No abnormality
Example 3 Ignition at 100% Ignition at 100% No abnormality
Comparative example 1 Ignition at 100% Can not be ignited Is easy to break
Comparative example 2 Ignition at 100% 60% ignition Is easy to break
From the analysis of experimental data, in examples 1-3 and comparative examples 1-2, the ignition rate of the ignition rod prepared in each example and each comparative example without being subjected to humid environment treatment reaches 100%, but the ignition rate of the ignition rod prepared in each example 1-3 still reaches 100% after being subjected to humid environment treatment, but the ignition rod prepared in comparative example 1 cannot ignite after being subjected to humid environment treatment, while the ignition rod prepared in comparative example 2 can ignite a part of the ignition rod after being subjected to humid environment treatment, and the ignition rate is 60%; and the strength of the ignition stick prepared in the comparative example 1 and the ignition stick prepared in the comparative example 2 are small and easy to crack after being treated in a humid environment, which is consistent with the hydrophilic and hydrophobic performance test result of the materials in the table 1. Comparative example 1 compared with example 1, in comparative example 1, during the preparation process of the ignition bar, no binder is added to the components, and the rest conditions are unchanged; comparative example 2 in the manufacturing method of the ignition bar, the outer surface of the manufactured ignition bar was not coated with the adhesive, and comparative analysis revealed that the addition of the adhesive can enhance the moisture resistance of the ignition bar, and in particular, when the outer surfaces of the ignition bar were all coated with the adhesive, the moisture resistance of the ignition bar was further increased, and when the outer surfaces of the ignition bar were coated with the adhesive, the ignition bar had a higher strength and was prevented from being chipped even though it was subjected to a humid environment treatment.
In the invention, a binder is introduced in the process of preparing the ignition rod, during the preparation process of the binder, urea and formaldehyde solution are used as raw materials, hydroxymethyl urea is generated by adjusting the pH value of the solution to be alkalescent, and products mainly comprising hydroxymethyl urea and dimethylol urea are obtained by controlling the proportion of formaldehyde and urea; further adding a proper amount of acid to adjust the pH of the solution to be acidic, and under the acidic condition, condensing between free hydroxymethyl and hydroxymethyl or reacting with-NH 2 NH reaction to form linear or branched polymer emulsion, adding tetrafluorobenzoic acid, and esterifying to modify the hydroxyl radical of the polymer with tetrafluorobenzoic acid monomer to introduce great amount of fluorocarbon radical; due to the presence of a large number of fluorocarbon groups and benzene rings,the chain segment movement is hindered, the crystallinity of the polymer is reduced, so that the prepared adhesive has better toughness and ductility, and the melting point of the polymer is reduced, thereby facilitating ignition; on the other hand, because fluorine is the element with the largest electronegativity, the bond energy of the C-F bond is large, the combination of the fluorine atom and the carbon atom is firmer, the binding effect of the fluorine atom on the electron cloud outside the core and the bonding electron cloud of the fluorine atom is stronger, the polarizability between the C-F bonds is low, the intermolecular force of the polymer containing the C-F bonds is lower, and the polymer has excellent water resistance and oil resistance, therefore, the prepared adhesive containing a large number of fluorocarbon groups is coated on the surface of the ignition rod to show good moisture resistance.
In the preparation process of the ignition rod, the adhesive and the components are fully mixed and then are pressed in a fragrance making machine, after molding and drying, a layer of adhesive is coated on the surface of the sample, and after the sample is dried in the sun, the sample is put into a model again. Because the adhesive coated on the outer surface of the ignition rod is consistent with the adhesive added in the preparation process, when the ignition rod is extruded again, the polymer molecular chains of the adhesive positioned on the surface of the ignition rod and the molecular weight of the adhesive polymer contained in the ignition rod are mutually entangled to form a cross-linked reticular structure, so that the two are combined more tightly, and the strength of the prepared ignition rod is ensured.
