Problems solved by technology

[0008] 1. After the drug is refined at a high temperature above 270°C, the active ingredients will be lost, which will affect the efficacy of the drug
[0009] 2. The lead red used in the production is a heavy metal and is poisonous. Both the smoke and waste residues discharged during production contain lead, which pollutes the environment, and the plaster also contains lead, which is harmful to humans.
[0010] 3. Long production cycle (15 days) and low labor efficiency
[0011] 4. High energy consumption
If the refining temperature is low and the refining time is short, the softening point of the paste will be low, and the paste will not flow into a thick paste and cannot be molded; on the contrary, if the refining temperature is high and the refining time is too long, the softening point of the paste will The point is high, too hard and brittle, the plaster is not easy to stick to the skin, and the medicine cannot be used

Abstract

The invention discloses a preparation method for black plaster, and belongs to the technical field of preparation for externally applied drugs. Compared with a conventional method, the preparation method disclosed by the invention can prevent pollutions and harm to the environment and the human body by adopting a pressure-sensitive adhesive, rosin and zinc oxide to replace red lead, reduces a refining temperature of production to 180 DEG C, effectively reduces loss of effective ingredients of the drugs, and omits two processes of releasing fire-toxin and melting the plaster, so that a production period is shortened by 7-10 days and about 50% energy is saved. The black plaster prepared by the method doesn't fall off or move after being adhered to skins, is moderate in stickiness, has no pollutions to the skins, and is non-toxic, harmless and environment-friendly. The black plaster can bring about historic change to the production of traditional plaster in China.
