Description
Technical Field
The invention relates to a preparation method of special oil for porous granular ammonium nitrate fuel oil explosive, belonging to the technical field of petrochemical industry.
Background
The porous ammonium nitrate fuel oil explosive is a novel explosive and is prepared by mixing porous ammonium nitrate and common diesel oil, but the common diesel oil has a low flash point (45-65 ℃), belongs to dangerous chemicals, and has high purchasing cost and strict storage requirements. Especially in winter, the use of low-grade diesel oil (higher management and purchase cost and poorer safety) at outdoor temperature is also considered. Meanwhile, most components of the additives contained in diesel oil in the market have no benefit on the production of the ammonium nitrate fuel oil explosive, and individual components can play a role in inhibiting the explosion process to influence the explosion effect. In addition, the diesel oil has poor safety in the production and transportation of the ammonium nitrate fuel oil explosive. In the outdoor high-temperature burning rock area, spontaneous combustion is easily caused.
Disclosure of Invention
The invention aims to solve the defects of diesel oil used by porous granular ammonium nitrate fuel oil in the prior art, and provides a preparation method of special oil for porous granular ammonium nitrate fuel oil explosives.
Technical scheme
A preparation method of special oil for porous granular ammonium nitrate fuel oil explosives is characterized in that naphthenic base crude oil is used as a raw material, a normal two-line oil is selected for distillation in a normal pressure distillation device, the distillation range is controlled at the temperature of 240-.
A porous granular ammonium nitrate fuel oil explosive comprises porous granular ammonium nitrate and the special oil for the porous granular ammonium nitrate fuel oil explosive, wherein the weight ratio of the porous granular ammonium nitrate to the special oil for the porous granular ammonium nitrate fuel oil explosive is 100 (4.5-5.5).
The preparation method of the porous granular ammonium nitrate fuel oil explosive comprises the following steps: adding the special oil for the porous granular ammonium nitrate fuel oil explosive into porous granular ammonium nitrate and uniformly mixing to obtain the special oil.
The invention has the beneficial effects that: compared with common diesel oil, the special oil for the porous granular ammonium nitrate fuel oil explosive has the following advantages:
(1) the flash point is high: the flash point (opening) temperature is above 120 ℃, so that the possibility of spontaneous combustion of oil products in the production and transportation processes can be effectively reduced, and the safety coefficient is improved;
(2) the oil absorption rate is high: the porous ammonium nitrate granules can be mixed with the special oil more fully, and the blasting quality is improved;
(3) the condensation point is low: the low-temperature fluidity is good, and the low temperature of above-25 ℃ can be resisted;
(4) the material cost is low: the price is equivalent to that of diesel oil, but the price is lower than the average price of diesel oil used in winter and summer, the key addition usage proportion is greatly reduced (the addition proportion of the original diesel oil is higher than 6%, and the addition proportion of the special oil for the porous granular ammonium nitrate fuel oil explosive is below 5.5%), thereby the cost is greatly reduced compared with the original diesel oil.
