Abstract

The invention discloses a preparation method of an ethylene-vinyl acetate copolymer (EVA) flame retardant material with high stability and mechanical performance. The EVA flame retardant material is prepared from the following ingredients in parts by mass: 100 parts of EVA, 60 to 300 parts of modified hydroxides, 0.5 to 5 parts of antioxidants and 0.5 to 5 parts of light stabilizers, wherein the modified hydroxides are prepared from 50 to 250 parts of magnesium hydrate and / or aluminum hydroxide and 10 to 50 parts of polyethylene glycol (PEG) and / or glyceryl monoaliphatic ester. The prepared EVA material has excellent flame retardant performance, heat resistant performance and mechanical performance, and is suitable for injection formation or compression molding; products can be applied tothe fields of cable coating, sound insulation plates, gymnastic mats, high-grade shoes, high-performance composite materials and the like.

Description

technical field [0001] The invention discloses a method for preparing a flame-retardant polymer material, in particular to an EVA flame-retardant composite material and a preparation method thereof, and belongs to the technical fields of polymer material processing and polymer materials. Background technique [0002] EVA material is a thermoplastic with excellent performance, which has excellent chemical and physical properties, especially in terms of strength, corrosion resistance and insulation. Therefore, it is widely used in the fields of building materials, furniture, packaging and high-performance composite materials. However, EVA has poor flame retardancy and will burn violently in the event of a fire, posing a safety hazard. And light and oxygen can easily cause EVA to age. In order to prevent such problems from happening, it is generally necessary to add a variety of additives. Traditional flame retardants generally contain antimony, etc., which have certain poll...
