Process for preparing nano CaCO3 modified tremolite powder filling master

Abstract

The invention discloses a mother-particle filling preparing method of nanometer CaCO decorative tremolite powder, which comprises the following steps: disposing nanometer CaCO3 through through disperser; mixing the CaCO3 with tremolite at certain rate; shocking the block nanometer CaCO3 on the irregualar surface of tremolite; preparingt plastic filler. The plastic inorganic filler contains 76-84 percent tremolite, 8-16 percent carrier resin, 1-3 coupler and 2-8 lubricator. The invention improves the plastic transparent property and aging resistance property.

Description

technical field

[0001] The invention relates to a filler material for preparing plastics, in particular to an inorganic filler masterbatch used in the preparation of plastics and a preparation method thereof, belonging to the field of materials. Background technique

[0002] In order to save petroleum resources and reduce the cost of plastic products, inorganic powder filled masterbatches have been widely used in the field of plastics. The most widely used is CaCO 3 Filler masterbatch, followed by talcum powder and wollastonite powder filler masterbatch. With the development of society and the improvement of people's living standards, consumers have higher and higher requirements for the quality and performance of plastic products. For inorganic powder-filled modified plastics, it is not only required to reduce the cost, but also to increase or improve certain properties of the product. However, the commonly used inorganic powder filled masterbatches are difficult to meet...
