Smokeless environment-friendly birthday candle with color flame

Abstract

The invention discloses a smokeless environment-friendly birthday candle with a color flame and a preparation method of the smokeless environment-friendly birthday candle. The preparation method comprises the following steps of: with trimethyl citrate as a main combustible ingredient and octadecanamide, stearic acid and tristearin as a plasticizer, an emulsifying agent, a releasing agent and a dispersing agent, additionally adding erucamide, oleamide, propyl gallate, 2-hydroxy-4-n-octyloxybenzophenone, triclosan, 10,10'-oxybisphenoxarsine and an alcohol solubility pigment, melting all the materials at the temperature of 90-95 DEG C, and uniformly mixing the melted materials to obtain a candle material; dissolving a color flame color former in purified water to prepare a color forming liquid with the mass concentration of 3-6%, placing a cotton thread into the color forming liquid to soak for 2-24hours, then, taking the cotton thread out and drying the cotton thread to obtain a wick; and threading the wick on a candle machine, pouring the candle material on the machine, introducing cooling water, solidifying the candle material, then, forming and carrying out mould stripping. The preparation method is simple in production process, low in cost, labor-saving and suitable for large-scale mechanical production; and the produced candle with the flame is stable in flame, bright and pure in color of the flame, free of smoke and lachrymation in combustion and long in quality guarantee period.

Description

technical field [0001] The invention relates to a colored flame candle and a preparation method thereof, in particular to a smokeless and environment-friendly colored flame birthday candle and a preparation method thereof. Background technique [0002] At present, the colored flame candle technology on the market basically uses trimethyl citrate as the main combustion agent, and stearic acid amide, stearic acid or glyceryl tristearate as plasticizers, emulsifiers, release agents, dispersants, etc. Additives and combustion aids, oil-soluble pigments as appearance improvers, lithium, potassium, sodium, copper, calcium, magnesium, boron, barium and other metal salts as coloring agents. The wick mainly uses two, such as the patent document CN102559397A, in order to make the candle emit bright red, yellow, blue, green, purple, white and other flame colors, a double-core treatment is adopted, one burning core and one color-emitting core are kneaded to form a candle. wick.

AI Technical Summary

Problems solved by technology

[0003] Although there are many documents about colored flame candles, there are few colored flame candle products on the market. The reason is that there are the following problems: (1) Poor stability: existing colored flame candles are generally affected by climate change Larger, short storage time, and some cannot even achieve half a year storage period, especially in the humid southern regions

Usually due to powdering, mildew, fading, moisture absorption and other problems, which seriously restrict the sales of products

(2) complex process: the wick is generally processed through multiple processes, such as CN100557004C of the patent document, the wick has been soaked repeatedly for a long time in alkali and acid, which takes a long time and also needs to consume a large amount of labor

(3) The degree of mechanization is low: due to the relatively small cold shrinkage of the raw materials of the current colored flame candle formula, it is determined that the production process must be completed by splitting the mold, which requires a large amount of labor. Mass production is also not conducive to promotion

(4) quality is not guaranteed: it is mainly reflected in the following aspects: first, in the current technology of making colored flame candles, glyceryl tristearate and stearic acid are often used separately, that is, only glyceryl tristearate is used or stearic acid

When only glyceryl tristearate is used, because of its high oiliness, it often floats on the wax material in large quantities, and it is not easy to completely dissolve in the wax material, resulting in uneven mixing of the wax material, which leads to the color flame candle prepared from the upper layer of wax material. Failed, with a yellow flame

When only stearic acid is used, the amount is not easy to control. When the amount is too small, the toughness is not enough and it is brittle. When the amount is too much, it will form acid spray phenomenon, resulting in yellow core and uneven surface coloring of colored flame candles.

(5) The appearance is not beautiful enough, it is not easy to color and the coloring is uneven

However, after testing, the miscibility between oil-soluble pigments and trimethyl citrate is poor, it is difficult to color or some pigments are hardly colored, or the coloring is uneven. At present, the formula of colored flame candles is poor in heat resistance, easy to oxidize and even coke. During the long heating production process It is easy to change color and deteriorate, so that the strength of the product is weakened, the color difference is serious, and the appearance is unsatisfactory, so the appearance quality of the produced products cannot be guaranteed

(6) Many documents have no fundamental solution to phenomena such as mildew and deterioration and pulverization

In addition, it takes too long to dry naturally, air dry or dry in the shade, and the gravity will make the soaked hair coloring agent accumulate in the lower part, and then the candles made of the wick obtained by air drying or natural air drying, some parts of the hair color It is very good, but some colors cannot be emitted, and the accumulated color flame agent will form a very hard scab after the water dries up and cannot be operated.

Therefore, the quality balance of each candle cannot be guaranteed in mass production

Moreover, the repeated treatment of the wick will seriously damage the structure of the wick, making it easy to break, greatly weakening the oil absorption capacity, and affecting the combustion effect. Therefore, it is necessary to add another burning wick, which not only increases the cost but also consumes time.
