Nanometer inorganic plastic toughening master batch

Abstract

The invention relates to the technical field of inorganic plastic, in particular to a nanometer inorganic plastic toughening master batch. The nanometer inorganic plastic toughening master batch comprises the following components in parts by weight: 23-31 parts of polyethylene, 3-12 parts of elastomer, 2.5-3.8 parts of inorganic filler, 3.6-5.3 parts of nanosilicon dioxide, 15-25 parts of kieselguhr, 12-18 parts of methylcellulose, 13-16 parts of super fine calcium carbonate, 3-9 parts of antioxidant and 35-50 parts of ethylene-acrylic ester. After the above formula is adopted, according to the nanometer inorganic plastic toughening master batch, section performance between nanometer inorganic ions and polymers can be effectively improved, the master batch can be easily dispersed, and the reinforcing and toughening effect of the nanometer inorganic ions can be fully performed.

Description

technical field [0001] The invention relates to the technical field of inorganic plastics, in particular to a toughening masterbatch of nano inorganic plastics. Background technique [0002] Many polymers are brittle at room temperature, which greatly reduces their use value. For example, polystyrene has good transparency and easy processing, but it needs to add rubber to increase toughness to have higher impact strength. The additives that give plastics better toughness are called tougheners, also known as impact modifiers. The main purpose of the current development of toughening agents is to improve the brittleness of rigid polyvinyl chloride. The continuous growth of rigid polyvinyl chloride usage in the world is closely related to the increasing development of toughening agents and processing modifiers. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a toughening masterbatch of nano inorganic plastics. ...
