Further, the heating temperature in the step S1 is 70-80 ℃.
Further, the preparation method of the laundry aroma-retaining bead further comprises the step of treating the essence microcapsules by using liquid paraffin, wherein the addition amount of the liquid paraffin is 1-2 times of the mass of the essence microcapsules.
In the technical scheme of the invention, PEG-8000 is used as a main carrier matrix, essence can be effectively loaded, and after being heated and melted, the essence is condensed again to obtain a solid fragrance retaining bead main body; sodium bicarbonate is heated to decompose and release CO in the production process2And the micro bubbles are left in the liquid PEG-8000 to form a loose microporous structure after being condensed, so that the density is reduced and the micro bubbles are easier to dissolve; the glycerol and the PEG-8000 are mixed and can be used as a cosolvent to accelerate the speed of dissolving and releasing essence of the fragrance retaining bead, the silicone oil can enable clothes to be more flexible, in addition, the glycerol and the silicone oil have a defoaming effect to a certain degree, when the addition amount is too small, the effect of promoting dissolution and softening clothes is limited, when the addition amount is too large, the glycerol and the silicone oil can obviously destroy a liquid film on the surface of bubbles, prevent the formation of the bubbles and promote the destruction of the bubbles, and cannot form a loose microporous structure, so that the solubility of the fragrance retaining bead for washing clothes is reduced, and the control of the addition amount of the glycerol and the silicone oil in a proper range is very important for the solubility of the fragrance retaining bead for washing clothes; the essence releases fragrance in the washing process, so that the washing experience is improved; the essence microcapsules are attached to clothes and release fragrance when the clothes are dried and worn, so that the washed clothes can retain fragrance for a long time; the sodium sulfate is used as a filler, so that the cost is reduced; the 2, 6-di-tert-butyl-4-methylphenol can prevent the essence from being oxidized and changing taste, and simultaneously has the functions of sterilization and bacteriostasis.
The essence microcapsule is prepared by wrapping raw materials such as essence, plant essential oil and the like with special materials by a modern scientific and technological means to form microcapsule emulsion, and can reduce the volatility of the essence, control the release of the fragrance and prolong the fragrance retention time. The inventor tries to add the fragrance microcapsules into the raw materials for preparing the fragrance-retaining beads in the early period, but the fragrance-retaining beads for washing need to be heated and kept in a heat preservation state in the preparation process, the fragrance microcapsules are easy to break under the heating condition, so that wall materials cannot be well deposited around core materials to form microcapsules, the fragrance in the microcapsules is easier to volatilize, and the formed microcapsules can also break, so that the properties and fragrance-retaining functions of the microcapsules are damaged. The liquid paraffin is a white semitransparent oily liquid, has good stability to light, heat and acid, and is mainly used for manufacturing washing powder and synthetic detergents at present. In the technical scheme of the invention, the inventor tries to treat the essence microcapsules by liquid paraffin before adding the essence microcapsules, and after the essence microcapsules are treated by the liquid paraffin, the surfaces of the essence microcapsules are uniformly coated by the liquid paraffin for the second time, so that the essence microcapsules are stable under the heating condition and keep a more lasting fragrance-retaining function.

Test example I test of dissolution speed of fragrance-retaining beads for washing clothes
The laundry fragrance beads prepared in examples 1 to 6 and comparative examples 1 to 5 were taken, and the diameters thereof were 1cm, dissolved in water having the same volume and a temperature of 10 ℃, left naturally, and the dissolution was started by pressing a stopwatch, and the dissolution of the fragrance beads was observed, and when the fragrance beads were completely dissolved, the dissolution was stopped by pressing the stopwatch, and the dissolution times of the fragrance beads were recorded.
TABLE 1 complete dissolution time of laundry fragrance beads
| Item | Time (min) for complete dissolution of fragrance bead |
| Example 1 | 21.2 |
| Example 2 | 20.2 |
| Example 3 | 22.9 |
| Example 4 | 22.1 |
| Example 5 | 21.6 |
| Example 6 | 22.5 |
| Comparative example 1 | 40.2 |
| Comparative example 2 | 38.2 |
| Comparative example 3 | 33.5 |
| Comparative example 4 | 22.6 |
| Comparative example 5 | 37.2 |
As can be seen from table 1, the laundry perfume beads prepared in examples 1 to 6 of the present invention have a shorter complete dissolution time than the comparative examples, and the laundry perfume bead prepared in example 2 has the shortest complete dissolution time, which is the best example of the present invention. Comparative example 1 no sodium bicarbonate was added and the complete dissolution time of the laundry fragrance bead prepared therewith was greatly increased; as can be seen from comparative examples 2 and 3, the addition of too little or too much glycerin affects the complete dissolution time of the laundry fragrance-retaining beads; it can be known from comparative example 5 that the excessive mass of the added silicone oil affects the complete dissolution time of the fragrance-retaining beads for washing clothes, because the glycerin and the silicone oil have defoaming effect to a certain extent, when the adding amount is too small, the effect of promoting dissolution by the glycerin and the effect of promoting softening by the silicone oil are limited, and when the adding amount is too large, the glycerin and the silicone oil can obviously destroy liquid films on the surfaces of bubbles, prevent the formation of the bubbles and promote the destruction of the bubbles, cannot form a loose microporous structure, and reduce the solubility of the fragrance-retaining beads for washing clothes, so that the adding amount of the glycerin is 3-8%, and the adding amount of the silicone oil is 1-4% in the range.
Test example two, measurement of fragrance bead Density for washing clothes
Taking the laundry fragrance retaining beads prepared in the examples 1-6 and the comparative example 1 respectively, wherein the diameter of the laundry fragrance retaining beads is 1cm, and performing a density test by a specific gravity method under the same condition, wherein the specific details are as follows: a500 mL volumetric flask was taken, 450.00mL of water was transferred to the flask by using a 50mL pipette and weighed to obtain a mass W1, and then fragrance-retaining beads were added to the flask to raise the water level to the scale, and the flask was weighed again to obtain a mass W2 and a density ρ (W2-W1)/50.
Table 2 laundry fragrance bead density test results
| Item | Average density (g/cm)3) |
| Example 1 | 1.13 |
| Example 2 | 1.10 |
