In a preferred embodiment, the flame retardant is at least one selected from the group consisting of a silicon flame retardant, a nitrogen flame retardant, a phosphorus flame retardant, a nitrogen-phosphorus flame retardant and a boron flame retardant.

In a preferred embodiment, the flame retardant substance is a nitrogen-phosphorus flame retardant. In the application, the nitrogen-phosphorus flame retardant is preferably a water-based nitrogen-phosphorus flame retardant treatment agent, and a purchasing manufacturer of the water-based nitrogen-phosphorus flame retardant treatment agent is not specifically limited and can purchase the nitrogen-phosphorus flame retardant treatment agent from Hubei Yongbantai and New materials Co.

Through a large number of experiments, the applicant finds that the flame retardant effect of the immortal moss can be improved by adding sodium salt, particularly sodium chloride, into the treatment liquid in the system and then matching with the water-based nitrogen-phosphorus flame retardant treatment agent added into the system, and when the mass ratio of the sodium chloride to the water-based nitrogen-phosphorus flame retardant treatment agent is 1: and when the time is 10 hours, the flame retardant effect of the prepared perpetual moss is optimal, and the perpetual moss can keep lasting bright color and luster and the hand feeling of fresh and alive plants. The applicant speculates that the possible reason is that the addition of the sodium chloride has a color fixing effect on moss re-dyed by the dye, but the increase of the sodium chloride content can cause the whitening phenomenon of the finally prepared permanent moss and can cause the hard and crisp permanent moss, but the sodium chloride content is reduced and the flame retardant effect of the permanent moss is reduced.

The second aspect of the invention provides a preparation method of flame-retardant perpetual moss, which comprises the following steps:

(1) preparing a treatment solution: dissolving the flame-retardant matrix and the alkali metal salt in a solvent, and uniformly stirring to obtain a treatment solution;

(2) the immortal moss is obtained by removing impurities, decoloring, dyeing, treating with a treatment solution and drying.

In a preferred embodiment, the method comprises the following steps:

(1) preparing a treatment solution: dissolving the flame-retardant matrix and the alkali metal salt in a solvent, and uniformly stirring to obtain a treatment solution;

(2) removing impurities from the moss, removing soil, dust, weeds, fallen leaf fragments and insects on the surface of the moss or/and the root of the moss, soaking and decoloring the decontaminated moss, drying and sterilizing the moss after decolorization, then dyeing the moss again by using a dyeing agent, treating the dyed moss by using a treatment solution after drying the moss, and then drying the moss to obtain the perpetual moss.

In a preferred embodiment, the drying manner in step 2 is at least one selected from drying in the shade, air drying, and low-temperature drying.

In a preferred embodiment, the treatment liquid in step 2 is treated by immersion treatment.

After the applicant tried various combinations of preparation methods, it was found that drying the moss after immersion treatment with the treatment solution resulted in the best permanent moss in every aspect of performance. The applicant conjectures that the moss plants in nature or the moss plants after one-time processing treatment are immersed in the treatment liquid to be dyed, the treatment liquid is uniformly attached to each part of the moss, the flame retardant effect of the moss is good, and the service cycle is long; if the spray coating treatment is carried out by using the treatment fluid, the surfaces of the pseudostem and pseudoroot parts in the moss are not adhered with the treatment fluid, and certain negative effects on flame retardance, brightness maintenance and service cycle extension are achieved.
