Problems solved by technology

However, the surface of heavy calcium carbonate is hydrophilic and oleophobic, the specific surface area is large, the surface energy is high, and the particles are easily agglomerated. When directly or in large quantities filled in organic matrix materials, it is not only difficult to disperse evenly, but also has a weak binding force with the matrix. , resulting in defects at the two-phase interface and some performance degradation of the composite

Embodiment Construction

[0011] A preparation method of modified ground calcium carbonate for flame retardant cable material:

[0012] Weigh heavy calcium carbonate 100 by weight (kg), octylphenol polyoxyethylene ether 1, Pinga O 0.3, dioctyl maleate 1, zinc stearate 0.2, magnesium oxide 0.1, polyethylene wax 0.3, UV absorber UV-P 0.1, Chitosan 2, Polyphosphoric acid 1, Methyltriethoxysilane 3,

[0013] Dry the calcium carbonate at 82°C until the water content is less than 0.3%, then add it to the high-speed mixer, add octylphenol polyoxyethylene ether in proportion, add O flatly, and high-speed at a speed of 800-1000 rpm Stir for 4 minutes, then add dioctyl maleate, stir at high speed for 6 minutes, then add zinc stearate, magnesium oxide, polyethylene wax, ultraviolet absorber UV-P, chitosan, polyphosphoric acid, methyl Triethoxysilane was then stirred at a high speed of 1000-1200 rpm for 18 minutes, then dried and ground to obtain modified calcium carbonate.

[0014] We made hard and soft PVC tes...

Abstract

The present invention provides modified heavy calcium carbonate for a fire retardation electric cable material. The modified heavy calcium carbonate is prepared from the following raw material components, by weight: 95-100 parts of calcium carbonate, 1-2 parts of octylphenol polyoxyethylene ether, 0.2-0.3 part of peregal O, 1-1.5 parts of dioctyl maleate, 0.2-0.4 part of zinc stearate, 0.1-0.2 part of magnesium oxide, 0.1-0.3 part of polyethylene wax, 0.1-0.4 part of an ultraviolet absorber UV-P, 1-2 parts of chitosan, 1-1.5 parts of polyphosphoric acid, and 2-3 parts of methyltriethoxysilane. The preparation method comprises: drying calcium carbonate, adding other raw materials according to the ratio, completely mixing in a high speed stirrer, and carrying out drying and grinding to obtain the finished product. The obtained modified calcium carbonate has characteristics of good dispersity and good ultraviolet resistance, and can be used for fire retardation electric cable materials so as to reduce cost and improve various processing performances of the electric cable material.

Description

technical field [0001] The invention relates to the field of inorganic fillers, in particular to a modified calcium carbonate for anti-ultraviolet cable materials and a preparation method thereof. Background technique [0002] Ground calcium carbonate is a commonly used inorganic filler. It is widely used in rubber, plastics, coatings and other fields due to its wide source and low price. However, the surface of heavy calcium carbonate is hydrophilic and oleophobic, the specific surface area is large, the surface energy is high, and the particles are easily agglomerated. When directly or in large quantities filled in organic matrix materials, it is not only difficult to disperse evenly, but also has a weak binding force with the matrix. , leading to two-phase interface defects and some performance degradation of composite materials. Therefore, in order to broaden its application field, it is necessary to modify the surface of heavy calcium carbonate to make its surface lipo...
