Problems solved by technology

However, photoluminescent materials, including rare earth luminescent pigments, semiconductor luminescent materials, etc., are expensive, far higher than the usual material prices of civilian fireworks, so it is difficult to widely promote them in the market

Embodiment 1

[0033] Example 1: blue flame, golden spray fountain cold fireworks

[0034] The formula used is: ammonium perchlorate 20%, nitrocellulose 50% (average nitrogen content 11.8%), 100-mesh titanium powder 20%, 100-mesh copper oxide powder 5%, fluororubber 5%; all are percentages by mass. The total amount of charge can be determined according to the demand. According to the opening size of the discharge tube, the total charge of 20 grams can be set off for about 20 to 40 seconds.

[0035] The preparation process is as follows: (1) mixing: uniformly mix the above materials; (2) sieving: remove particles larger than 100 mesh; (3) charge: fill the blue cold smoke flower agent that has been mixed evenly into the fountain fireworks In the empty cylinder of the product, tamp it to a pressure of 1 MPa to ensure that there is no gap in the drug body; (4) Packaging: Use soil or a primer to seal the opening of the charge end, and then insert the lead wire at the opening of the injection end....

Embodiment 2

[0036] Embodiment 2: blue flame, golden large particle spray fountain cold fireworks

[0037] The formula used is: ammonium perchlorate 20%, nitrocellulose 50% (average nitrogen content 11.8%), 60 mesh titanium powder 20%, 100 mesh copper oxide powder 5%, fluororubber 5%; all are percentages by mass. The total amount of charge can be determined according to the demand. According to the opening size of the discharge tube, the total charge of 20 grams can be set off for about 20 to 40 seconds.

[0038] The preparation process is as follows: (1) mixing: uniformly mixing the above materials; (2) sieving: removing particles larger than 60 mesh; (3) charging: filling the uniformly mixed blue cold smoke into the fountain fireworks In the empty cylinder of the product, tamp it to a pressure of 1 MPa to ensure that there is no gap in the drug body; (4) Packaging: Use soil or a primer to seal the opening of the charge end, and then insert the lead wire at the opening of the injection en...

Embodiment 3

[0039]Example 3: Yellow flames, golden spray fountain cold fireworks

[0040] The formula used is: 20% of ammonium perchlorate, 50% of nitrocellulose (average nitrogen content 11.8%), 20% of 100-mesh titanium powder, 5% of 100-mesh sodium chloride powder, and 5% of fluororubber; all are in mass percentage. The total amount of charge can be determined according to the demand. According to the opening size of the discharge tube, the total charge of 20 grams can be set off for about 20 to 40 seconds.

[0041] The preparation process is as follows: (1) mixing: uniformly mix the above materials; (2) sieving: remove particles larger than 100 mesh; (3) charge: fill the blue cold smoke flower agent that has been mixed evenly into the fountain fireworks In the empty cylinder of the product, tamp it to a pressure of 1 MPa to ensure that there is no gap in the drug body; (4) Packaging: Use soil or a primer to seal the opening of the charge end, and then insert the lead wire at the openin...

Abstract

The invention relates to a formula and a preparation process of novel indoor and outdoor cold firework. The novel indoor and outdoor cold firework comprises the following components in percentage by mass: 20%-70% of energetic substances, 10%-40% of an oxidizing agent, 10%-40% of one or more kinds of metal powder, 0%-20% of a flame color reaction material and 0%-5% of a binder. The preparation process comprises the steps of material mixing, particle sieving, firework charging and barrel packaging. Compared with the prior art, the novel indoor and outdoor cold firework of the invention has the following characteristics that elementary substances, compounds and mixtures capable of generating flame color reaction with fireworks during combustion are added, so that the novel indoor and outdoorcold firework has the characteristics of wide color gamut (covering the wavelength range of 400 nm-760 nm), multiple colors, narrow electromagnetic wave full width at half maximum, high contrast ratioof set-off patterns and the like, ensures reasonable cost, and can be widely accepted by consumers when being used for civil entertainment firework products or used for various celebrations or parties and other festival occasions.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers, in particular to a novel formula of indoor and outdoor cold fireworks and a preparation process thereof. Background technique [0002] The light color, heat and power produced by traditional spray fireworks mainly come from the burning of black powder. Black gunpowder is made by mixing potassium nitrate (or potassium perchlorate), charcoal and sulfur. Since it burns to generate air-polluting substances such as potassium sulfide, nitrogen oxides, and carbon monoxide, it is not suitable for indoor discharge, and the effect of outdoor discharge is also poor. Disadvantaged by smoke occlusion and pollution. In order to solve the problem of smog produced by the burning of traditional spray fireworks, for example, the patent publication No. CN1059400A discloses a firework formulation made of nitrocellulose, magnesium-aluminum-cerium alloy, metal titanium and shellac in a certain prop...
