Problems solved by technology

There are many disadvantages in the traditional process: if a large area of ​​drying field and drying shed is required, a large amount of labor is required, the drying time is long, the construction period is also affected by rainy days, and the medicine is scattered, the stagnation of the medicine is large, and the safety risk high
Therefore, the drying time is long, the production cycle is long, and the production efficiency is low
[0005] In order to solve the problems existing in the prior art due to the use of water-based slurry primers, resulting in long air-drying time, long production cycle, low production efficiency, large drug storage stagnation, and high safety risks, it is necessary to develop a new paper lead wire. Pulp primer, the inventor found through a large number of tests that nitrocellulose and phenolic resin are used as adhesives, and anhydrous methanol or ethanol is used as a solvent to make glue for pulp lead paper leads. The air-drying time is short and the production efficiency is high. , the adhesion is tight, the medicine does not disperse, and the sealability and stability are all good, thus completing the present invention

[0032] The preparation method is the same as the preparation process of Example 1 (wherein, the unit can also be parts by weight).

Embodiment 7

[0034] Preparation of Paper Leads for Fireworks and Firecrackers

[0035] 1) Twist the lead paper and the lead medicine into wool paper lead wires,

[0036] 2) Pass the semi-finished paper lead through or coat the glue obtained in Examples 1-6;

[0037] 3) Air-dry for 1-2 hours, remove methanol or ethanol, and obtain paper leads.

[0038] In embodiment 7, the paper leads drawn by the glue slurry obtained in Examples 1 to 6 are respectively referred to as embodiment 1 paper leads, referred to as "real 1", embodiment 2 paper leads, referred to as "real 2", and embodiment 3 paper leads. Lead, be called for short " real 3 ",, embodiment 4 paper lead, be called for short " real 4 ", embodiment 5 paper lead, be called for short " real 5 ", embodiment 6 paper lead, be called for short " real 6 ".

Abstract

The invention relates to glue for fireworks paper leads. The glue comprises the following ingredients in part by weight: 15-150 parts of nitrocotton, 10-40 parts of phenolic resin and 1000 parts of absolute methanol or ethanol. The glue is used for pulping and guiding paper leads, the air drying time is short, the production efficiency is high, the adhesion is tight, the medicine is not loose and the priming effect is good.

Description

technical field [0001] The invention belongs to the technical field of fireworks and firecrackers, and in particular relates to a glue suitable for pulp-fired fireworks and firecracker paper leads and a preparation method thereof. Background technique [0002] The production of fireworks and firecrackers has a history of hundreds of years in our country. Traditional crafts are mainly made in hand-made workshops. Among them, paper fuses are also referred to as "paper fuses", and the following are the same. They have been in the production mode of family workshops for a long time, and it has not developed into non-isolated, close-range machine production in recent years. [0003] The traditional paper leads mainly use paper to wrap the priming medicine, dip into the paste formed by rice soup or rice soup plus starch for sizing, and then place it in the open to dry. There are many disadvantages in the traditional process: if a large area of ​​drying field and drying shed is re...
