A novel composite solid fuel and its preparation method

Abstract

The invention discloses a novel composite solid fuel and a preparation method thereof. The novel composite solid fuel disclosed by the invention is composed of the following components in parts by weight: 3-5 parts of a stearic acid, 1-3 parts of glycerine, 20-30 parts of hexamethylene tetramine, 30-50 parts of ethanol, 20-30 parts of triethyl citrate, 10-20 parts of polyethylene glycol 400, 1-3 parts of potassium hydroxide, 1-3 parts of alum, 3-6 parts of paraffin wax, 6-8 parts of span-60, 2-10 parts of nitrocellulose, 4-8 parts of a composite additive, and 30-50 parts of water. The fuel disclosed by the invention is prepared by compounding various calorific-value components, and through the synergistic effect of the various calorific-value components, a defect that the calorific value of a single calorific-value component is too large or too small can be overcome, thereby obtaining a better application effect.

Description

technical field [0001] The invention belongs to the technical field of chemical fuels, and more specifically relates to a novel composite solid fuel and a preparation method thereof. Background technique [0002] When going to other places, or carrying out outdoor activities, such as heating, barbecue, picnic, etc., fuel is needed to achieve the purpose. If fuels such as common gasoline and diesel oil are used, there are disadvantages such as inconvenient portability and bad safety. [0003] The Chinese invention patent with the patent number of 2013105548501 discloses a solid fuel. The disclosed proportion is composed of hexamethylenetetramine, paraffin, stearic acid and ethanol according to a certain proportion. The main shortcomings of its existence are: 1. The ingredients are too simple, there is no good synergistic effect between them, and there are no other auxiliary ingredients, resulting in low utilization rate of raw materials and low calorific value; 2. The stabil...

Problems solved by technology

If you use ordinary gasoline, diesel and other fuels, there are disadvantages such as inconvenient to carry, poor security, etc.

[0003] The Chinese invention patent with the patent number of 2013105548501 discloses a solid fuel. The disclosed proportion is composed of hexamethylenetetramine, paraffin, stearic acid and ethanol according to a certain proportion. The main shortcomings of its existence are: 1. The ingredients are too simple, there is no good synergistic effect between them, and there are no other auxiliary ingredients, resulting in low utilization rate of raw materials and low calorific value; 2. The stability of the finished product is not good, resulting in inconvenient use and potential safety hazards

[0004] The Chinese patent No. 2012103351689 discloses a solid fuel for picnics. The disclosed proportion is composed of ethanol, ethylene glycol, stearic acid, zinc stearate, zinc sulfate, sodium hydroxide, potassium hydroxide and potassium nitrate Composition; its main shortcomings are: 1. The calorific value component is single, which leads to a relatively limited range of use; 2. The component does not contain stabilizing and promoting ingredients, which makes its use less reliable, and the raw material The utilization rate is not high
