Problems solved by technology

Styrene and divinylbenzene are widely used monomers for making microcapsules, and they are highly controllable, but they do not have polymer chains that can form a cross-linked phase with the outside world, so physical modification is not very impressive

Abstract

The invention discloses a multifunctional anionic polymer composite additive and a preparation technology thereof, and relates to the field of additives. The additive is prepared from the following raw materials in parts by weight: 1-100 parts of a 1,3-butadiene-styrene-divinyl benzene (B-sty / DVB) terpolymer and 0-50 parts of a nano anion additive. The multifunctional anionic polymer composite additive has the beneficial effects that (1) the polymer product contains a polybutadiene polymer block chain, so that the polymer product can form an interface phase together with partial organic interface; (2) the polymer product contains the polybutadiene polymer block chain, so that the chain length can be regulated by adding a monomer and an initiator; (3) a capsule formed by the product wraps partial anion additive in the product, so that the partial anion additive is not easily separated in the modification process; (4) the mixture wraps the anion additive, so that all characteristics of the anion are included; and (5) the mixture is polymer and inorganic nonmetal blend, so that the mixture has physical characteristics of the polymer and the inorganic nonmetal.

Description

technical field [0001] The invention relates to the field of additives, in particular to a multifunctional anion polymer composite additive which is a mixed product of a terpolymer and anion and a preparation process thereof. Background technique [0002] Negative ion additives have important applications in asphalt, ceramics, rubber and other materials. Negative ions have an inactivation effect on microorganisms, bacteria, and viruses, and can achieve the purification effect of air or material surfaces. General anion additives are physically blended in colloids and asphalt, and a single anion additive exists in the blend, which has no obvious change in the physical properties of the original. [0003] Microcapsule technology has been used in many fields: 1) used in sachets to slowly emit fragrance; 2) used in textiles for antibacterial and deodorizing; 3) used in special paints to improve fire resistance. [0004] Microcapsules can be obtained by emulsion polymerization, s...
