Problems solved by technology

However, calcium carbonate particles have strongly hydrophilic hydroxyl groups distributed on the surface, which are alkaline, have different interfacial properties with organic polymer matrix materials, and have poor compatibility, making it difficult to disperse evenly in the matrix material and form a strong bond with the matrix material. Bonding force, resulting in interface defects between the two materials, reducing some mechanical properties of the composite material

Abstract

The invention discloses a corrosion-resistant modified calcium carbonate with good comprehensive properties. The corrosion-resistant modified calcium carbonate with good comprehensive properties is characterized by being prepared from the raw materials in parts by weight: 90-95 parts of calcium carbonate, 4-6 parts of bisphenol A epoxy resin, 3-5 parts of alkyd resin, 2-3 parts of silicon carbide, 3-3.5 parts of pelelith powder, 2-2.5 parts of zinc carbonate, 1-2 parts of asbestos, 2-3 parts of glass powder, 3-5 parts of polytetrafluoroethylene, 1-2 parts of glycine betaine, 0.8-1.3 part of zinc gluconate and 3-4 parts of modified titanium dioxide. The corrosion-resistant modified calcium carbonate with good comprehensive properties has the characteristic of good compatibility of a high-molecular polymer and also has the characteristic of corrosion resistance because silicon carbide, the pelelith powder, the glass powder, polytetrafluoroethylene and the like are added to cover and modify calcium carbonate; as a result, modified calcium carbonate is high in binding force, and can be used as an industrial filler without reducing the comprehensive properties of the product.

Description

Technical field [0001] The invention relates to the field of industrial fillers, in particular to a modified calcium carbonate with good comprehensive performance and corrosion resistance and a preparation method thereof. Background technique [0002] Calcium carbonate is a very important functional inorganic filler, which is widely used in industrial fields such as plastics, rubber, coatings and papermaking. However, calcium carbonate particles have strong hydrophilic hydroxyl groups distributed on the surface, which are alkaline. They have different interface properties from organic polymer matrix materials and have poor compatibility. It is difficult to disperse uniformly in the matrix material and form a strong bond with the matrix material. The bonding force causes the interface defects between the two materials, which reduces certain mechanical properties of the composite material. Changing the performance of traditional calcium carbonate products and improving their appli...
