Abstract

The invention discloses a method for preparing a composite plastic modifying agent based on modified magnesite and belongs to the field of plastic modifying agent preparation. According to the method, pretreatment is performed on the magnesite at high temperature, pretreated magnesite grains are mixed with the modifying agent to achieve modification under the ultrasonication, modified grains are obtained through filtration and extraction, and natural ingredients are extracted to be mixed with the modified grains to obtain the composite plastic modifying agent. The method has the advantages that the preparation method is simple, the obtained composite plastic modifying agent is good in dispersibility, the anti-shock strength of the obtained polyethylene or polypropylene plastic is 8% higher than that of other methods after the composite plastic modifying agent is added into the polyethylene or polypropylene plastic to be used, the elasticity and the stress crack resistance are good, and the method is worth popularizing and utilizing.

Description

technical field [0001] The invention relates to a method for preparing a composite plastic modifier based on modified magnesite, and belongs to the field of plastic modifier preparation. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. Polyethylene is a polymer formed by the polymerization of ethylene. The product has been developed for about 60 years. The global polyethylene production ranks first among the five general-purpose resins. It is the most commonly used plastic polymer in the world, with an annual consumption rate of more than 50 billion pounds per year, and more than 70% of Porex products use polyethylene. Polypropylene is a general-purpose plastic used second only to polyethylene. This is mainly because polypropylene has go...
