Abstract

The invention provides a water-based inorganic filler dispersant. The raw materials of the water-based inorganic filler dispersant include the following components: in parts by mass, a carboxylic acidmonomer, silsesquioxane particles, a long-chain monomer, purified water, a molecular weight control agent, an initiator, chiral phosphoric acid and a compatibilizer, and the water-based inorganic filler dispersant is of a powder form, has a microscopic morphology of uniform spherical particles with an average particle diameter of 12-25 [mu]m. The prepared water-based inorganic filler dispersant has uniform powder and convenient and simple use, and does not fail after storage is performed for 24 months in a normal temperature environment, and a good dispersing effect on common inorganic materials and high anti-interference performance are achieved.

Description

technical field

[0001] The invention belongs to the technical field of polymer synthesis, and relates to a dispersant, in particular to a water-based inorganic filler dispersant. Background technique

[0002] The dispersion of inorganic materials in aqueous solution has always been a major problem in coatings, construction and other industries. The existing dispersants have many major disadvantages, such as: excessive addition, selectivity to the system, and some inorganic materials will appear The problem of failure, there may be environmental pollution problems, and there are certain requirements for equipment. These are major problems that restrict industrial development. Therefore, developing a new type of decentralized product with wide adaptability is becoming an important demand of the society.

[0003] Chinese patent 201510773263.0 discloses a water-based paint dispersant, which is made of the following components: acrylic acid, methyl methacrylate, white carbon bla...
