Adding nano-precipitated barium sulfate can increase the whiteness of the product


Use nano barium sulfate to replace different proportions of red, yellow, green, and blue pigments in polyolefin masterbatches. Use a colorimeter to measure the tinting strength, reflectance and transmittance of films and sample products made from masterbatches. And other properties, to study its effect on the color performance of masterbatch. The results show that the substitution amount of nano-barium sulfate in different color pigments is different. In general, the average replacement amount can reach about 20%, which not only does not affect the coloring of the product, but also reduces the production cost.


The application of nano-barium sulfate to replace part of titanium dioxide in polyolefin white masterbatch was studied, and its effect on the color performance of white masterbatch was studied. A photoelectric spectrophotometer and a spectrophotometer were used to measure the hiding power and whiteness of the films and sample products made with white masterbatch, and the dispersion of the pigment was quantitatively characterized by an image analyzer. The results show that when nano BaS04 replaces 20% of TiO2 pigment, while the other properties of the white masterbatch remain basically unchanged, the hiding power of the product is greatly improved, and the whiteness is increased by 2.75%. For different crystalline TiO2 pigments, the addition of nano-barium sulfate improves the hiding power and whiteness of the product.
