A kind of NEW TYPE OF COMPOSITE solid fuel and preparation method thereof
Technical field
The invention belongs to chemical fuel technical field, more specifically relate to a kind of NEW TYPE OF COMPOSITE solid fuel and preparation method thereof.
Background technology
Going to other places, or carrying out outdoors, such as, warming oneself, roast, picnic etc., need to achieve the goal by fuel.If use the fuel such as common gasoline, diesel oil, then exist and carry inconvenience, the weak points such as security is bad.
The patent No. be 2013105548501 Chinese invention patent disclose a kind of solid fuel, proportioning disclosed in it is made up of according to a certain ratio hexamethylenetetramine, paraffin, stearic acid and ethanol, its main deficiency existed is: 1, composition is too simple, each other without good synergistic effect, and without other ancillary components, cause its raw material availability low, thermal value is little; 2, the stability of finished product is also bad, causes use not too convenient, also has potential safety hazard.
The patent No. be 2012103351689 Chinese patent disclose a kind of Solid fuel for picnic, proportioning disclosed in it is made up of ethanol, ethylene glycol, stearic acid, Zinic stearas, zinc sulfate, sodium hydroxide, potassium hydroxide and saltpetre; Its deficiency mainly existed is: 1, calorific value component is single, causes its use range to be subject to larger limitation; 2, do not contain stable in component and promote composition, the reliability that this makes it use is not enough, and the utilization ratio of raw material is not high.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, a kind of NEW TYPE OF COMPOSITE solid fuel and preparation method thereof is provided.
For achieving the above object, this invention takes following technical scheme:
A kind of NEW TYPE OF COMPOSITE solid fuel, with parts by weight, composed of the following components:
Stearic acid: 3 ~ 5, glycerol: 1 ~ 3, vulkacit H: 20 ~ 30,
Ethanol: 30 ~ 50, triethyl citrate: 20 ~ 30, poly(oxyethylene glycol) 400: 10 ~ 20,
Potassium hydroxide: 1 ~ 3, alum: 1 ~ 3, paraffin: 3 ~ 6, this coils-60:6 ~ 8,
Soluble cotton: 2 ~ 10, composite additive: 4 ~ 8, water: 30 ~ 50.
Described composite additive, with parts by weight, composed of the following components:
Sodium-chlor: 3 ~ 6, SODIUMNITRATE: 1 ~ 3, ferric oxide: 0.1 ~ 0.5,
Diatomite: 10 ~ 20, Zinic stearas: 0.3 ~ 0.5, sodium bicarbonate: 1 ~ 3.
The solid-fuelled preparation method of described NEW TYPE OF COMPOSITE, comprises following technological step:
(1) preparation of composite additive; By proportioning, each component is mixed;
(2) stearic acid, vulkacit H, paraffin and alum are put into grinder-mixer successively to pulverize, then mix, obtain powder mixture; Then add step (1) preparation-obtained composite additive, be uniformly dispersed;
(3) soluble cotton is dissolved in ethanol, after being uniformly dispersed, obtains glutinous thick liquid; Then add poly(oxyethylene glycol) 400 and glycerol, be uniformly dissolved;
(4) triethyl citrate, potassium hydroxide are distinguished soluble in water, stir;
(5) product of step (2), (3) (4) is put into together Mixer pot mixing, and add other components of residue, stir insulations 10 ~ 20 minutes at 60 ~ 80 DEG C, then mixture injected container, after normal temperature condensation finished product.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention is composited by multiple calorific value component, acts synergistically between multiple calorific value component, can overcome the defect that the thermal value of single calorific value component is excessive or too small, thus obtains a preferably result of use;
2, the present invention adds adaptive additive in formula, it can form the molecular structure of long-chain with stearic acid, and make the stearic usage quantity as gelifying agent be reduced to original 1/6, coagulation force strengthens 6 times, the burning later stage is unlikely flame-out ahead of time, and heat can discharge completely; Meanwhile, adding of composite additive, also good combustion-supporting effect can be played;
3, add certain stablizer in the present invention's formula, weak molecular linkage can be formed with calorific value component and be combined, thus substantially increase stability in use of the present invention; Thus making its use range wider, security is higher.
4, this product raw material is easy to get, cheap, easily lights, and can not spontaneous combustion explode, firepower is strong, thermal value is high, safe and reliable; Can be used as the energy and be widely used in all respects such as industrial production, civilian, field work, tourism.
