Description

Technical Field

[0001] The invention relates to a pyrotechnic agent for fireworks and firecrackers. Background Art

[0002] Fireworks and firecrackers are an excellent traditional cultural industry in China. Now the requirements for the safety and environmental protection of fireworks and firecrackers are getting higher and higher. Therefore, it is necessary to develop a combustible with a high ignition point, low friction and impact sensitivity, good chemical stability, and effective reduction of combustion smoke.

[0003] Natural plant fibers are the most abundant renewable resources in nature, and are biodegradable and environmentally friendly. Their main components, cellulose, hemicellulose, and lignin, have functional groups in their macromolecular structures that can participate in chemical reactions, and can be used to prepare functional materials for a variety of purposes. Moreover, the raw materials are widely available and inexpensive. Summary of the invention

[0004] The purpose of the present invention is to provide a combustible with high ignition point, low friction impact sensitivity, good chemical stability and effective reduction of combustion smoke. The technical scheme adopted by the present invention is a micro-smoke plant fiber powder for improving the safety of pyrotechnics, which is composed of the following raw material components in weight ratio: 30-60 parts of bamboo powder, 15-60 parts of cotton powder, 15-60 parts of corn starch, 15-25 parts of terpene resin, 5-15 parts of fir charcoal powder, and 10-25 parts of chlorinated paraffin; the above raw materials are crushed to 120-140 meshes respectively and then mixed according to the general method, and the mixture is ball-milled to 160-200 meshes to obtain.

[0005] Preferably, the weight ratio of each raw material component is: 45-55 parts of bamboo powder, 25-35 parts of cotton powder, 35-50 parts of corn starch, 20-22 parts of terpene resin, 8-10 parts of fir charcoal powder, and 15-20 parts of chlorinated paraffin.

[0006] Preferably, the weight ratio of each raw material component is: 50 parts of bamboo powder, 30 parts of cotton powder, 45 parts of corn starch, 21 parts of terpene resin, 9 parts of fir charcoal powder, and 18 parts of chlorinated paraffin.

[0007] The application of the micro-smoke plant fiber powder in fireworks and firecrackers.

[0008] The beneficial effects of the present invention are:

[0009] 1. The micro-smoke plant fiber powder has good safety and stability. When added to the formula of pyrotechnic powder, it can reduce the sensitivity of the pyrotechnic powder and the sensitivity of the pyrotechnic powder in production operation, thereby reducing the occurrence of production accidents.

[0010] 2. The micro-smoke plant fiber powder effectively reduces the burning speed of products such as spray flowers and incense sticks, making the product's effect medicine burn evenly, with distinct layers, clear flower shapes and brighter colors.

[0011] 3. The micro-smoke plant fiber powder has excellent environmental performance. Due to the regulation of the burning rate of the pyrotechnic effect agent, the generation of smoke and dust is reduced, and the micro-smoke and micro-dust effects can be achieved during use. The manufacturing process does not require nitration process treatment, and there is no wastewater, no exhaust gas discharge, no toxicity, and natural degradation in the whole process.

[0012] 4. The micro-smoke plant fiber powder has good applicability. ① The raw materials for making this material are widely available, all from nature; ② The material is made by physical mixing in a commonly used ball mill, the process is simple and safe, and it is non-toxic to the human body; ③ There are no special requirements for the use process of making fireworks and firecrackers, and it is easy to operate. ④ Cheap. Bamboo and wood materials are used as the main raw materials, the cost is relatively low, and the cost after deep processing is only more than 10,000 yuan, while the single-base powder material with similar performance is more than 50,000 yuan, and it is safer than the single-base powder, and can save product production costs in the storage, transportation, and use links. ⑤ It can be used as a speed control agent for spray flower and incense firework products, as a combustible for other types of fireworks products, and can also be used as a desensitizing agent in pyrotechnics.

[0014] Figure 1 Inspection report for sampled pyrotechnic powder. DETAILED DESCRIPTION

[0015] Preparation Example: Weigh the raw material components according to the following ratio: 50 parts of bamboo powder, 30 parts of cotton powder, 45 parts of corn starch, 21 parts of terpene resin, 9 parts of fir charcoal powder, and 18 parts of chlorinated paraffin. Each component is crushed to 120-140 mesh and then mixed according to the general method. The mixture is put into a ball mill and crushed to 160-200 mesh to obtain micro-smoke plant fiber powder.

[0016] In other preparation examples, the weight proportions of each raw material component can be arbitrarily selected within the following ratio range, which will not be described in detail: 30-60 parts of bamboo powder, 15-60 parts of cotton powder, 15-60 parts of corn starch, 15-25 parts of terpene resin, 5-15 parts of fir charcoal powder, and 10-25 parts of chlorinated paraffin;

[0017] Application example 1: Making cake fireworks. 15 parts of micro-smoke plant fiber powder, 30 parts of ammonium perchlorate, and 12 parts of sponge titanium powder. The firing speed is uniform when visually inspected, achieving micro-smoke and micro-dust, and the fireworks shape meets the requirements.

[0018] Since the micro-smoke plant fiber powder was approved as a joint research project on May 23, 2024, through a large amount of theoretical, experimental research and product production, the safety, environmental protection, applicability and theoretical basis of the material have been experimentally certified, tested and comprehensively evaluated.

[0019] Passed the inspection of National Fireworks and Firecrackers Product Quality Inspection and Testing Center - test report number: WAY20242065. After the micro-smoke plant fiber powder was added to the pyrotechnic powder to prepare the effect medicine (that is, in the state of containing oxidant), the friction and impact sensitivity were both detected to be 0; the ignition point was 339.2℃, which is high; the moisture content was 0.75%, the moisture absorption rate was 1.54%, and the pH value was 5.8. Compared with the requirements of relevant national industry standards, the material indicators are excellent.

[0020] Its safety performance is also reflected in: the manufacturing process does not require nitration process treatment; the main manufacturing raw materials are plant fibers with biodegradable and environmentally friendly characteristics, rather than petrochemical raw materials. Because plant fibers have natural ductility and softness, they are used in fireworks, just like a layer of sponge wrapped on the surface of fireworks, thereby alleviating the friction and collision of fireworks in production, reducing the occurrence of static electricity, and reducing sensitivity. Tests and tests have proved that this material can reduce the sensitivity of any fireworks formula. In addition, the micro-smoke plant fiber powder has a slow burning speed, with a burning rate of 0.0042mm / s. Adding it to fireworks effectively reduces the burning speed of products such as spray flowers and incense sticks, making the product's effect medicine burn evenly, with distinct layers, clear flower shapes, and brighter colors; due to the regulation of the burning speed of the fireworks effect medicine, the generation of smoke and dust is reduced. The cake fireworks products produced can achieve micro-smoke and micro-dust effects during use through on-site observation by experts of the project team. The expected purpose of the project establishment has been achieved.

[0021] Application Example 2: Making cake fireworks. 10 parts of micro-smoke plant fiber powder, 45 parts of ammonium perchlorate, 20 parts of sponge titanium powder, 15 parts of strontium carbonate, 8 parts of polyvinyl chloride, and 8 parts of magnesium aluminum alloy.
