Preparation method of flexible atmosphere lamp and flexible atmosphere lamp

The preparation method of the flexible atmosphere lamp comprises the steps that (1) 40-70 parts of alkaline earth metal carbonate, 30-50 parts of aluminum oxide, 1-5 parts of europium oxide, 2-6 parts of dysprosium oxide and 3-7 parts of boric acid are stirred and mixed, and then luminescent powder with the particle size smaller than 3.4 micrometers is obtained through sintering, smashing and screening; (2) mixing 60-100 parts of PVC powder, 8-15 parts of a plasticizer, 3-8 parts of a stabilizer, 4-10 parts of a flame retardant, 3-9 parts of an antistatic agent, 0.3-3 parts of an anti-tarnish additive and 1-2 parts of ethylene bis stearamide to obtain a second mixture; (3) adding 50-90 parts of luminescent powder into the second mixture to obtain a third mixture; and (4) carrying out calendering or injection molding on the third mixture to obtain the flexible atmosphere lamp. The contents of all the substances are counted in parts by weight, and the atmosphere lamp with high luminous intensity and high flexib
