Embodiment 1-4

[0040] figure 1 Shown is the SEM picture of the modified nano barium sulfate that embodiment 1 makes, as seen from the figure, the product that makes is nanoscale, good dispersibility. The products obtained in Examples 1-4 are tested by a Malvern particle size tester, and it is found that the average particle diameter of the modified nano-barium sulfate powder prepared by this method is controlled between 45-120nm, and the maximum particle diameter Below 3 microns, it has the advantages of easy dispersion, excellent heat resistance, high whiteness, and low moisture content, and can be applied to the reinforcement and toughening of pipes, sheets, films, non-woven fabrics, fibers, and injection-molded plastic products. Masterbatch.

[0041] Agglomeration is easy to occur when the addition ratio of ordinary modified nano-barium sulfate exceeds 80%, white spots that cannot be dispersed are prone to occur in film products, and broken filaments are prone to occur in fibers and non-...

Abstract

The invention discloses a preparation method of modified nano barium sulfate powder which is easy to disperse and good in heat resistance and an application of modified nano barium sulfate, and meanwhile provides a toughened and enhanced masterbatch prepared by taking the modified nano barium sulfate powder as a main body and a preparation method of the masterbatch. The invention has the beneficial effects that the prepared modified nano barium sulfate powder has the advantages of easy dispersion, excellent heat resistance, high whiteness, low water content and the like, and can be applied to preparing the toughened and enhanced masterbatch in the fields of tubular products, sheets, thin films, non-woven fabrics, fibers, injection molding plastic products and the like; the prepared masterbatch remarkably improves the mechanical properties such as tear strength and impact strength of the products such as thin films.

Description

technical field [0001] The invention relates to the preparation and application of an inorganic nano powder, in particular to the preparation and application of an easily dispersible heat-resistant nano barium sulfate. Background technique [0002] Due to its important structural properties such as quantum effect, size effect and surface effect, nano barium sulfate has become an important new high-grade functional filler in recent years. It not only has broad application prospects in many industrial fields such as rubber, plastics, inks, coatings, and papermaking, but also has broad application prospects in medicine, ceramics, cement, and composite materials. [0003] At present, there are two main production processes of nano barium sulfate, one is physical method and the other is chemical method. The so-called physical method is to put the dispersant, natural barium sulfate and zirconia beads in the aqueous solution and use a sand mill to perform multi-stage sand grinding...
