Different Heavy Calcium Carbonate in Unsaturated Polyester Furniture white Primer Applied Comparative Study
The study investigated the effects of purity and surface modification of calcium carbonate from different types of raw ores on the gloss,polishing,and anti settling properties of unsaturated polyester furniture white primer.The results showed that heavy calcium carbonate produced from dolomite and marble as raw materials had high glossiness in unsaturated polyester furniture white primer,but poor polishing performance and easy formation of hard precipitates,making it unsuitable for application in this system;The heavy calcium carbonate produced from calcite and marble as raw materials has significantly better polishing and anti settling properties than dolomite and marble raw materials;The heavy calcium carbonate modified with stearic acid has better glossiness,anti settling performance,and polishing performance than the untreated raw powder.
