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

[0013] A kind of preparation method of modified calcium carbonate for floor tiles,

[0014] First weigh 400 mesh heavy calcium carbonate 100, magnesium oxide 0.3, sodium tripolyphosphate 0.2, silane coupling agent KH5500.1, fatty acid glyceride 3, beryllium oxide 0.4, EVA resin 2, molybdenum oxide 0.3 by weight (kg). , hollow glass microsphere 0.6, bamboo charcoal fiber 1, then prepare according to the following steps:

[0015] (1) First, mix heavy calcium carbonate and magnesium oxide evenly, then dry at 90-100°C until the water content is below 0.5%, and then add it to a high-speed mixer;

[0016] (2) Mix sodium tripolyphosphate, silane coupling agent KH550, fatty acid glycerides, beryllium oxide, and EVA resin first, and then add them to calcium carbonate, at a temperature of 85-90°C, at a speed of 900-1000 rpm , stirring at high speed for 5-6 minutes;

[0017] (3) Add the remaining materials molybdenum oxide, hollow glass microspheres, and bamboo charcoal fibers to the m...

Abstract

The invention provides a modified calcium carbonate for floor tiles, which is prepared from the following raw materials in parts by weight: 95-100 parts of 400-mesh ground calcium carbonate, 0.2-0.4 part of magnesium oxide, 0.1-0.4 part of sodium tripolyphosphate, 0.1-0.2 part of silane coupling agent, 2-4 parts of fatty glyceride, 0.3-0.5 part of beryllium oxide, 1-3 parts of EVA (ethylene-vinyl acetate) resin, 0.2-0.4 part of molybdenum oxide, 0.6-0.8 part of hollow glass microsphere and 0.8-1.0 part of bamboo charcoal. The preparation method comprises the following steps: mixing part of materials, drying calcium carbonate, mixing, proportionally and sequentially adding the other raw materials in batches, thoroughly mixing in a high-speed stirrer, drying and grinding. The modified calcium carbonate provided by the invention has the advantages of favorable dispersity and favorable heat insulation property, and can lower the cost and enhance the working properties and heat insulation property of the product when being used in floor tiles.

Description

technical field [0001] The invention relates to the field of inorganic fillers, in particular to a modified calcium carbonate for floor tiles 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 lipophilic and hydropho...
