Description

Technical Field

[0001] The present application relates to the field of bubble candles, and more particularly, to a bubble candle and a preparation method thereof. Background Art

[0002] Bubble candles are made using a foaming process. Specifically, the raw materials are mixed, melted, and stirred, air is introduced and evenly dispersed, and then cooled to create a loose wax block. Compared to ordinary candles, bubble candles can save about 10-50% of raw materials and have better combustion performance.

[0003] Related technology discloses a bubble candle comprising 90-95% paraffin wax and auxiliary materials; 1-5% PP oil-based thickener; and 1-5% foaming agent, which is bicarbonate. When the wax melts at high temperatures, the foaming agent decomposes upon exposure to heat, producing gas. By adjusting the viscosity of the wax system to control the rate at which bubbles disperse, some bubbles are trapped within the wax, resulting in a bubble candle.

[0004] However, the above foaming method is easily affected by temperature, air pressure, quality of foaming agent, etc., the foaming effect is difficult to control, and bubbles of different sizes and uneven distribution may occur. During combustion, the flame may fluctuate or even extinguish itself, and there is a risk of candle collapse, which affects the burning effect and stability of the bubble candle, so it needs to be improved. Summary of the Invention

[0005] In order to obtain a bubble candle with uniform and stable bubbles, the present application provides a bubble candle and a preparation method thereof.

[0006] In a first aspect, the present application provides a bubble candle, which adopts the following technical solution:

[0007] A bubble candle comprising the following components in parts by mass:

[0008] 85-90 parts of liquid paraffin,

[0009] 8-12 portions of jelly powder,

[0010] 2-5 parts essential oil,

[0011] 1-5 parts of foaming agent,

[0012] 2-4 parts of foam stabilizer,

[0013] 0.1-0.5 parts of additives;

[0014] The foaming agent is microcrystalline cellulose particles carrying bicarbonate.

[0015] By adopting the above technical solution, liquid paraffin is formed into a jelly-like candle base under the action of jelly powder, and the essential oil can give the candle a rich fragrance. When the candle burns, the essential oil evaporates into the air, exerting the effects of soothing the mind, dispelling depression, and purifying the air. The foaming agent can distribute a number of bubbles in the candle. Microcrystalline cellulose particles carrying bicarbonate are used as the foaming agent. After heating, the bicarbonate decomposes and bubbles are generated with the microcrystalline cellulose particles as the center, which can make the bubbles uniform in size. At the same time, the microcrystalline cellulose can adhere to the interface between the bubble film and the liquid paraffin, strengthening the bubble film and making the bubbles more stable. The foam stabilizer can evenly distribute the bubbles, further enhancing the stability of the bubbles.

[0016] By selecting microcrystalline cellulose particles containing bicarbonate as a foaming agent and combining it with a foam stabilizer, bubbles are evenly and stably distributed in the candle matrix, thereby improving the stability of the bubble candle, ensuring the burning effect of the bubble candle, and reducing the possibility of flame self-extinguishing or candle collapse.

[0017] Preferably, the preparation method of the foaming agent comprises the following steps:

[0018] Dissolve bicarbonate in water at 20-25°C to prepare a saturated solution;

[0019] According to the bath ratio of 1:5-10, immerse the microcrystalline cellulose particles in the saturated solution, disperse them by ultrasonication, and soak them at 20-25°C for 1-3 hours;

[0020] After filtration, freeze-drying was performed to obtain a foaming agent.

[0021] By adopting the above technical solution, the microcrystalline cellulose particles have strong water absorption and adsorption properties, and can absorb a saturated bicarbonate solution, freeze-dry to remove excess water, and obtain microcrystalline cellulose particles loaded with bicarbonate crystals;

[0022] During the preparation process of the bubble candle, bicarbonate decomposes when heated to generate gas, which forms bubbles in the candle matrix with microcrystalline cellulose particles as the center; the microcrystalline cellulose particles are ultrasonically dispersed in a saturated solution so that the microcrystalline cellulose particles can evenly absorb the bicarbonate solution, which is conducive to making the sodium bicarbonate loaded on each microcrystalline cellulose particle approximately equal, ensuring that the size of the bubbles in the candle is approximately equal, and improving the uniformity and stability of the bubble candle.

[0023] Preferably, the microcrystalline cellulose particles are microcrystalline cellulose particles treated with a color-developing organic reagent, and the specific operation is as follows:

[0024] Adding a color-developing organic reagent to anhydrous ethanol, wherein the mass of the color-developing organic reagent is 1-5% of the anhydrous ethanol, and mixing well to obtain a dye solution;

[0025] The microcrystalline cellulose particles are added to the dye solution in a mass ratio of 1:(2-5), immersed for 1-3 hours, filtered out, washed, and dried at 70-85° C. to obtain color-changed microcrystalline cellulose particles.

[0026] By adopting the above technical solution, the microcrystalline cellulose is subjected to color-changing treatment, so that the color of the bubble candle is richer and the aesthetics of the bubble candle is improved.

[0027] Preferably, the foam stabilizer is an anionic surfactant and a silicone resin polyether emulsion in a mass ratio of 1:(0.8-1.5).

[0028] By adopting the above technical solution, the anionic surfactant can be distributed at the interface with the bubbles, making the bubbles more stable. The silicone resin polyether emulsion can adjust the distribution of the bubbles, so that the bubbles are arranged closely and neatly, making the bubble distribution more uniform, and further enhancing the stability of the bubble candle.

[0029] Preferably, the anionic surfactant is sodium α-olefin sulfonate.

[0030] By adopting the above technical solution, sodium α-olefin sulfonate can not only improve the surface tension of the bubbles and make the bubble film more stable, but also help to give full play to the foam-stabilizing effect of the silicone resin polyether emulsion and make the bubble distribution more uniform. In addition, sodium α-olefin sulfonate has good biodegradability and is safe and environmentally friendly.

[0031] Preferably, the jelly powder is a styrene block copolymer.

[0032] Preferably, the styrene block copolymer is a hydrogenated styrene-ethylene / butylene-styrene or styrene-ethylene / propylene-styrene block.

[0033] By adopting the above technical solution, the toughness of the bubble candle is enhanced, so that the bubble candle has a good molding effect.

[0034] Preferably, the auxiliary agent includes 0.1-0.2 parts of light absorber and 0.1-0.2 parts of light stabilizer.

[0035] The adoption of the above technical solution is conducive to improving the storage stability of the bubble candle.

[0036] In a second aspect, the present application provides a method for preparing a bubble candle, which adopts the following technical solution:

[0037] A method for preparing a bubble candle comprises the following steps:

[0038] Add jelly powder to liquid paraffin according to the ratio, heat to 100-120°C, stir until the jelly powder melts, cool to 70-85°C, add essential oil, additives, and foam stabilizer, stir and mix to obtain a jelly wax matrix;

[0039] The jelly wax base is cooled to 50-65° C., a foaming agent is added thereto while stirring, mixed evenly, and then injected into a mold, cooled and formed to obtain a bubble candle.

[0040] By adopting the above technical solution, a bubble candle with uniform and stable bubbles, good aesthetics, fragrant smell and good burning effect can be produced.

[0041] In a specific implementation plan, the steps include:

[0042] Add the foaming agent to the jelly wax base at a rotation speed of 1200-1500 r / min, and then stir at a rotation speed of 100-300 r / min for 8-15 minutes until the mixture is evenly mixed.

[0043] By adopting the above technical solution, high-speed stirring allows the foaming agent to disperse quickly, reducing the possibility of multiple small bubbles merging into large bubbles, and low-speed stirring allows the small bubbles to be evenly dispersed in the candle matrix, allowing the foam stabilizer to fully play its role and improve the uniformity of the bubbles.

[0044] In summary, this application has the following beneficial effects:

[0045] 1. Since the present application adopts microcrystalline cellulose particles containing bicarbonate as a foaming agent and cooperates with a foam stabilizer, the bubbles are evenly and stably distributed in the candle matrix, thereby improving the stability of the bubble candle, which is beneficial to ensuring the burning effect of the bubble candle and reducing the possibility of flame self-extinguishing or candle collapse.

[0046] 2. In this application, it is preferred to use anionic surfactant and silicone resin polyether emulsion with a mass ratio of 1: (0.8-1.5) as foam stabilizers. The anionic surfactant can be distributed at the interface with the bubbles to make the bubbles more stable. The silicone resin polyether emulsion can adjust the distribution of bubbles, so that the bubbles are arranged closely and neatly, making the bubble distribution more uniform, and further enhancing the stability of the bubble candle.

[0107]
