Abstract

The invention discloses an environment-friendly halogen-free flame-retardant masterbatch and a preparation method thereof. The environment-friendly halogen-free flame retardant masterbatch includes the following raw materials in parts by weight: 80-110 parts of polypropylene or polyethylene, 0.01-0.3 part of an antioxidant, 75-100 parts of a compound modified halogen-free flame-retardant powder, and 3-5 parts of polypropylene wax or polyethylene wax, wherein the compound modified halogen-free flame-retardant powder includes the following raw materials in parts by weight: 1-2 parts of a silanecoupling agent, 0.8-1.2 parts of stearic acid, 50-60 parts of hydrotalcite powder, 20-25 parts of aluminum hydroxide powder, and 10-15 parts of talcum powder. The flame retardant effect of the masterbatch is improved by adding the compound modified halogen-free flame-retardant powder into the formula of the masterbatch. The compound modified halogen-free flame-retardant powder is subjected to compound modification by selecting an inorganic flame retardant, and has good flame retardant effect by depending on organic combination and synergistic effect of all the components.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an environment-friendly halogen-free flame-retardant masterbatch and a preparation method thereof.
