Problems solved by technology

[0004] Nail-shooting tablets are usually composed of oxidizing agents, combustible agents, stabilizers, catalysts and adhesives, etc., which are all kneaded from powder, and are easy to absorb moisture and agglomerate during storage. In practical applications, misfires often occur. , Delayed ignition abnormality, there is a great potential safety hazard. In addition, after moisture absorption and agglomeration, each component will not burn sufficiently, resulting in small thrust and more residues. Therefore, the key to solving the above problems is to find a better one. Raw material ratio and moisture-proof improvement

Embodiment 1

[0031] The present embodiment prepares a kind of moisture-proof ammonium perchlorate, and concrete implementation process is as follows:

[0032] Step A1: Take the agitator equipped with a gas replacement protection device, drive out the air in the agitator with dry nitrogen, add 2kg of commercially available ammonium perchlorate to the agitator, and then add tetrahydrofuran to the agitator until Submerge ammonium perchlorate in tetrahydrofuran, turn on the agitator until the ammonium perchlorate is suspended in tetrahydrofuran, keep stirring, slowly add acetone to the agitator, and observe the dissolution of ammonium perchlorate through the sight glass until the perchlorate The ammonium is completely dissolved, stop adding acetone, pump the mixed solution into the crystallizer, depressurize the mixed solution to make the acetone volatilize, and the acetone is almost volatilized, then the mixed solution is suction filtered, and the concentrated solution vacuumed to 2kPa, And h...

Embodiment 2

[0036] The present embodiment prepares a kind of moisture-proof ammonium perchlorate, and concrete implementation process is as follows:

[0037] Step A1: Take the agitator equipped with a gas replacement protection device, drive out the air in the agitator with dry nitrogen, add 2kg of commercially available ammonium perchlorate to the agitator, and then add tetrahydrofuran to the agitator until Submerge ammonium perchlorate in tetrahydrofuran, turn on the agitator until the ammonium perchlorate is suspended in tetrahydrofuran, keep stirring, slowly add acetone to the agitator, and observe the dissolution of ammonium perchlorate through the sight glass until the perchlorate Ammonium is completely dissolved, stop adding acetone, pump the mixed solution into the crystallizer, depressurize the mixed solution to make the acetone volatilize, and the acetone is almost volatilized, then the mixed solution is suction filtered, and the concentrated solution of the suction filter is vac...

Embodiment 3

[0041]Get potassium dichromate, potassium nitrate, tetrazene, barium nitrate, lead trinitroresorcinol and lead dioxide to pass through 200 mesh screens respectively, get the powder under the sieve, and follow the steps of potassium dichromate, potassium nitrate, Tetraazene, barium nitrate, lead trinitroresorcinol and lead dioxide are added into the pneumatic powder mixer according to the quantity and quality 10.5:2.2:0.7:6.7:5.9:1.3 and mixed evenly to make superfine reaction powder.

Abstract

The invention relates to a safe nail shooting tablet and a preparation method thereof, and belongs to the technical field of building construction. The nail shooting tablet is prepared from, by weight, 15-35 parts of damp-proof ammonium perchlorate, 5-15 parts of a rapid catalyst, 25-45 parts of superfine reaction powder, 10-25 parts of an ultrahigh-standard energy multiplier and 10-45 parts of superfine double-base powder. All the raw materials are mixed to prepare a batch, then the batch and an adhesive are mixed, kneaded and subjected to compression molding, and finally the surface is coated with composite coating glue. Irregular ammonium perchlorate sold in the market is recrystallized in a tetrahydrofuran-acetone solvent, a crystal form is modified, then the ammonium perchlorate is coated with a composite coating adhesive, the composite coating adhesive is prepared from nitrocotton, Arabic gum and a volatile solvent, after coating, the solvent is volatilized, a coating layer containing the nitrocotton is formed on the surface layer, Arabic gum forms a film to play a role in separation, ammonium perchlorate and internal batch are prevented from absorbing moisture and caking, a certain amount of nitrocotton has an ignition effect, and normal ignition of the nail shooting tablet is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a safe nail-shooting tablet and a preparation method thereof. Background technique [0002] The nail bullet is a part of the nail fastening equipment. The fastening equipment includes nails, nail bullets and nail shooters. The nail shooters shoot nail bullets to nail various nails directly into steel, concrete, brick masonry and other substrates. Steel parts, doors and windows, wood products, insulation boards, sound insulation boards, decorations and rings, etc. are permanently or temporarily fixed on the base. [0003] The nail-shooting tablet is assembled in the nail-shooting bullet to push the nail. Its working principle is that under the impact of the firing pin of the nail-shooting gun, the tablet located in the bottom edge of the nail-shooting bullet ignites, ignites the tablet in the bullet, and uses the tablet to burn The produced high-pressur...
