Problems solved by technology

However, breathable membranes made of PE are often not flame retardant, which limits their application range.
This is because the flame retardant of PE is usually modified by a large amount of inorganic or organic flame retardants. However, due to the poor compatibility between

Abstract

The invention discloses a material special for a breathable film with antiflaming effect and a preparation method of the material special for the breathable film with the antiflaming effect. The material special for the breathable film with the antiflaming effect is composed of the following component: by weight, 55-76 parts of linear low density polyethylene, 12-15 parts of high pressure low density polyethylene, 4-6 parts of styrene thermoplastic elastomer, 0.5-3 parts of antiflaming agent A, 3-8 parts of antiflaming agent B, 2-4 parts of surface treating agent, 35-65 parts of filling agent, 4-6 parts of styrene thermoplastic elastomer, 0.3-0.5 part of lubricant, and 0.4-0.6 part of antioxidizer. The components are put in a blender or a high-speed blending machine to be fully premixed in proportion, and then a double screw extruder is used for fusing and blending to extract granulation. The material special for the breathable film with the antiflaming effect has good processing features, and water vapor transmission rate (WVTR) of the breathable film prepared from the material special for the breathable film with the antiflaming effect can achieve 1800-200 grams/ (m 2* 24 hrs), and antiflaming effect can achieve DIN 4102-B2.
