Abstract

The invention discloses a waterproof flame-retardant biological membrane. According to the weight component ratio, the waterproof flame-retardant biological membrane comprises the following components: 85 to 95 parts of polylactic acid fiber, 5 to 8 parts of plasticizer, 1.1 to 1.3 parts of hydrophobic agent, 0.5 to 0.8 part of dispersing agent, 0.5 to 0.8 part of antioxidant, 0.5 to 0.9 part of vinyl ketone polymer additive, 0.4 to 0.8 part of starch phosphate reactive flame retardant, 0.2 to 0.4 part of lubricant and a proper amount of deionized water. The invention has the following advantages: when the produced biological membrane is discarded into the environment, the biological membrane is degraded and rotten in the environment, so that the environment is not polluted; the biologicalmembrane can be decomposed in an accelerated mode under the illumination condition, the degradation efficiency of the biological membrane is improved, and the pollutant accumulation time is shortened.

Description

technical field

[0001] The invention belongs to the technical field of thin films, and in particular relates to a waterproof flame-retardant biofilm and a preparation process thereof. Background technique

[0002] Hygiene film is a film used in diapers and sanitary napkins. It is a disposable product that cannot be modified. It is used in a very large amount and will be discarded directly after use; the hygienic film currently on the market They are all made of PE materials, and PE materials are difficult to degrade in the environment. When the used diapers and sanitary napkins are thrown into the environment, because they cannot be degraded, the hygienic film in the environment will cause a lot of pollution. White pollution. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides an environment-friendly, degradable, waterproof, flame-retardant biofilm and a preparation process thereof.

[0004] In order t...
