However, the existing protective films are all hard films, such as patent 201210188018.X, etc. are films formed by good solvents, which have poor flexibility. The protective film may crack. Once such a crack occurs, we usually cannot see it with the naked eye. If no timely treatment measures are taken, these tablets whose surface pr

preparation example Construction

[0071] For the preferred sealing technology solution, the sealant is heated and melted to a liquid state; the main body of the tablet is heated to about 5-55°C higher than the ambient temperature for a period of time; then the liquid sealant is sprayed on the main body of the tablet, after spraying Cool naturally to normal temperature to obtain the finished nail bullet for nail fasteners with an embedded film. The present invention further provides a method for preparing a moisture-proof plastic-cased nail-shooting bullet containing a nail-shooting bullet for a nail-shooting fastener. The nail-shooting bullet is prepared according to the above-mentioned preparation method, and then the following steps are performed:

[0072] E. Moisture-proof: Press the nail-shooting bullet obtained in step D into the drug chamber of the plastic shell, and immediately dip it in a moisture-proof agent (such as paraffin, ozokerite or refined butter, etc.) with a temperature lower than 60°C to exp...

Embodiment 1

[0073] Example 1 Preparation of nail-shooting bullets for nail-shooting fasteners and moisture-proof plastic-cased nail-shooting bullets

[0074] Based on the weight of nitrocellulose, 1 kg (100%) of Grade B nitrocellulose (dry weight) with a nitrogen content ≥ 13.12%, 80% ethyl acetate, and 20% supplementary water are weighed and measured according to their respective weight percentages .

[0075] Start the kneader, the speed of the kneader is less than 30 rpm, first add nitrocellulose and supplementary water, then add ethyl acetate, and stir the materials evenly for wet plasticization. Pour the wet plasticized material into the dryer, start the hot air blower, the temperature of the heating air is less than 45°C, the hot air passes through the material and takes away the solvent and moisture until the moisture content is lower than 0.8% and the residual solvent content is lower than At 1.3%, stop drying and discharge. Pour the dried material into a compression molding mach...

Embodiment 2

[0080] Based on the weight of nitrocellulose, 1 kg of B-grade nitrocellulose (dry weight) with nitrogen content ≥ 13.12%, 80% acetone, 20% supplementary water, and 1.0% dibutyl phthalate, according to their respective weight percentages Carry out weighing measurement, the sealing agent takes by weighing the paste lubricating grease that is equivalent to 3% of tablet main body weight.

[0081] Add dibutyl phthalate to an appropriate amount of acetone and stir evenly to form a plasticizing solution. Start the kneader, first add nitrocellulose, then add acetone, stir evenly, then add plasticizing solution, continue stirring for wet plasticization, wet plasticization temperature: <35°C, kneader speed <30 rpm.

[0082] All the other steps are the same as in Example 1.

Abstract

The invention provides a nail shooting pill for a nail fastening device and a manufacturing method of the nail shooting pill. The nail shooting pill comprises a nail shooting pill body and an embedded film, and the nail shooting pill body is wrapped with the embedded film. With energetic materials as the criterion, the nail shooting pill body is prepared from, by weight, 100% of the energetic materials, 30%-120% of a solvent, and 5%-25% of supplementary water. The embedded film wrapping the nail shooting pill body is prepared from, by the weight of the nail shooting pill body, 0.01%-4% of sealing agents. The preparation method of the nail shooting pill mainly comprises the technological steps of wet plasticization, drying, forming, blocking and the like. The nail shooting pill is provided with the multifunctional embedded wet film prepared from the sealing agents and has good water-proof, damp-proof, lubricating and burnout-proof functions and other functions.

Description

technical field [0001] The invention relates to a nail-shooting bullet for a nail-shooting fastener and a preparation method thereof, belonging to the field of nail-shooting bullets for a nail-shooting fastener. Background technique [0002] At present, the nail shooting bullets in the nail fastener (nail gun for short) industry are divided into steel shell nail shooting bullets and plastic shell nail shooting bullets. The former is to pack gunpowder with grains like fine sand in the steel shell, and the firing pin hits the primer at the bottom of the shell to ignite the gunpowder to do work; First put it into the plastic shell and then put it into the gun chamber. After the firing pin hits the tablet, the sensitivity of the tablet to the impact is used to generate combustion work. There are several different assembly methods for plastic shell nail bullets, and they are collectively referred to as shelled nail bullets or plastic shell nail bullets. Gunpowder tablets withou...
