Abstract

The invention discloses a grinding promoting coupling agent and a preparation method thereof. The grinding promoting coupling agent contains 30 to 35 weight percent of grinding aid and 41 to 51 weight percent of aluminic acid ester coupling agent. The preparation method is simple. The grinding promoting coupling agent has dual functions of grinding promotion and coupling and remarkable effects, and is applied to various inorganic powders such as heavy calcium carbonate, barite, talc powder and kaolin which are produced by a dry method. The grinding promoting coupling agent simplifies the dry method production process and synchronously completes the grinding and modification, thereby improving the production efficiency, saving the investment, the labor and the energy consumption, reducing the production cost and environmental pollution, and having wide application prospect.

Description

technical field [0001] The invention relates to a chemical auxiliary agent, in particular to a grinding aid coupling agent and a preparation method of the grinding aid coupling agent. Background technique [0002] In rubber, plastic, paint, ink, paper and other products, under the premise of ensuring the processing performance or physical and mechanical properties of the product, the organic polymer matrix is ​​usually filled with more inorganic powder to make composite materials to reduce The dosage of organic high polymer reduces the production cost. The most widely used inorganic powders are ground calcium carbonate and talcum powder. [0003] Because the surface of inorganic powder is strongly hydrophilic, and the particle surface area is large, the surface energy is high, and the polarity is strong, it is easy to absorb moisture and agglomerate during storage and transportation, which will affect the mechanical strength and surface finish of the composite material; at ...
