Abstract

The invention relates to the technical field of porous polymers, and provides a microporous polymer carrier which comprises the raw materials in parts by weight: 100-150 parts of polyolefin resin, 5-25 parts of a modifier and 0.1-5 parts of a nucleating agent, wherein the raw materials further comprise a foaming agent, and the addition amount of the foaming agent is 1-25% of the mass of the polyolefin resin. The microporous polymer carrier is suitable for adsorbing various assistants; the loading application range of the high-stability polymer carrier material is expanded; the microporous polymer carrier can be used for adsorbing substances such as an antibacterial agent, a plasticizer, a phase-change material, a light stabilizer, an antibacterial agent, an antioxidant, dry silane, an antistatic agent, color paste, a deodorant, spice and a catalyst, the foaming performance of the microporous polymer carrier is relatively stable, the foaming efficiency is improved, and micropores with uniform sizes can be formed.

Description

technical field [0001] The invention relates to the technical field of porous polymers, in particular to a microporous polymer carrier and its preparation method and application. Background technique [0002] In the research of materials science, people have noticed that many natural materials have excellent properties such as high porosity, low density, and large specific surface area due to their porous structure. Therefore, people have developed a variety of artificial porous materials, which can be divided into two categories: metal and non-metal, and can also be subdivided into different types of porous ceramic materials, polymer porous materials and porous metal materials. Among them, polyolefin has the advantages of high cost performance, good mechanical properties and stable thermal properties. It is widely used in various fields such as industry, agriculture, medical and health, and daily life. It is an important polymer material. Polymer porous materials have high ...
