Problems solved by technology

However, the addition of dispersants and surface modifiers greatly reduces the temperature window of nano-calcium carbonate, because commonly used dispersants and coupling agents are easy to decompose at high temperatures, causing bubbles, cracks, defects, deformation, etc., thus Affect the appearance, heat resistance and mechanical properties of materials

Abstract

The invention discloses a modified calcium carbonate with heat-isolating heat-insulating effect. The modified calcium carbonate is characterized by being prepared from the following raw materials in parts by weight: 90-95 parts of calcium carbonate, 5-7 parts of polyphenyl granules, 4-6 parts of hollow glass microballoons, 2-3 parts of adhesive mortar, 2-4 parts of bentonite, 2-3 parts of diatomite, 4-6 parts of epoxide resin, 5-7 parts of phenolic resin glue, 1-2 parts of polyethylene wax, 1-2 parts of zinc stearate and 3-4 parts of modified titanium dioxide. The modified calcium carbonate disclosed by the invention enhances the heat-isolating heat-insulating effect by being added with a small quantity of hollow glass microballoons with environmental-friendly heat-isolating effect and the mortar included in building materials and is enhanced in dispersing effect by being added with the modified titanium dioxide. According to the modified calcium carbonate, a filler produced through a simple production process has good binding force and is suitable for the addition application of a floor, a wall brick, a coating and the like.

Description

technical field [0001] The invention relates to the field of industrial fillers, in particular to a modified calcium carbonate with heat insulation effect 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. In the application field of calcium carbonate, most products belong to the category of polymers, such as plastics, rubber, adhesives, coatings, etc., and occupy an important market share. Modifiers play an important role in the performance and application of nano calcium carbonate. For example, the addition of dispersant can reduce the agglomeration of nanoparticles and improve the dispersion; the addition of surface modifier can improve the compatibility of nano-calcium carbonate in the polymer system. It can be seen that dispersants and surface modifiers are crucial for the application of nano-calc...
