A kind of healthy polyolefin foam material and preparation method thereof

Abstract

The invention relates to a healthy polyolefin foam material and a preparation method thereof, which is prepared by mixing, melting and extruding, preheating and foaming the following raw and auxiliary materials in mass ratio: 70-100 parts of polyolefin resin, negative ion functional master 20-50 parts of raw material, 15-30 parts of hydrophilic functional masterbatch, 1-5 parts of foaming agent, 1-5 parts of cross-linking agent, and 0-5 parts of color masterbatch. The health-type polyolefin foam material of the present invention adds negative ion mineral materials and hydrophilic fullerene compounds into the formula, and has the advantages of air purification, surface anti-greasy, anti-static effects and the like. Utilizing the pyroelectricity and piezoelectricity of negative ion mineral materials can effectively increase the concentration of negative ions in the surrounding environment. At the same time, the hydrophilic group of the hydrophilic fullerene compound can form a hydrogen bond with water, which cuts off the connection between the pollutant and the polyolefin surface, and can also quickly leak the accumulated static charge to achieve the purpose of antistatic.

Description

technical field

[0001] The invention relates to a polyolefin foam material and a preparation method thereof, in particular to a healthy polyolefin foam material and a preparation method thereof. Background technique

[0002] Polyolefin plastics have a wide range of applications, have good physical, chemical and mechanical properties, good toughness, flexibility and cushioning properties, and have properties such as electrical insulation and heat insulation. They are widely used in packaging, chemical industry, construction and other fields. Polyolefin foams are widely used and one of the first foams to be successfully produced. As early as 1941, DuPont of the United States successfully prepared LDPE foam by using the nitrogen method. After decades of development, polyolefin foams have matured and diversified in terms of varieties and applications. With the continuous deepening of theoretical research and the advancement of foaming technology, foamed plastics have made grea...
