Embodiment 1

[0026] A preparation method for a composite flame retardant filler, comprising the following steps:

[0027] The raw ore of barium sulfate is roughly crushed, cleaned, and crushed once to obtain a raw ore with a diameter of 5-10cm, which is then put into the silo for secondary crushing to obtain a material with a diameter of 5-10mm, and finally dried by a ring roller mill. Method grinding, obtain 600 purpose barium sulfate powder;

[0028] Add 600-mesh barium sulfate powder and magnesium chloride according to the mass ratio of 4:1 and add water to form a slurry with a solid content of 75%. During the preparation process, add lignosulfonate compound grinding aid, and then control the temperature of the slurry at 70- Constant temperature stirring wet grinding at 80°C, adding 4‰ sodium polyacrylate dispersant, 3‰ sodium polycarboxylate dispersant and calcium hydroxide equal to the molar number of magnesium chloride during the stirring process to prepare 6000 The purpose of compo...

Embodiment 2

Abstract

The invention provides a composite flame-retardant filler preparation method. The composite flame-retardant filler preparation method includes the steps of adding water in barium sulfate powder and magnesium chloride to prepare a pulp material, wherein, the barium sulfate powder has a size of 600-800 meshes, the mass ratio of the barium sulfate powder to the magnesium chloride is (4-6): 1, the prepared pulp material has solid content of 70-80%; adding dispersing agents during preparation, stirring at a constant temperature, grinding in wet, adding the dispersing agents and calcium hydroxide during stirring to prepare a composite pulp material has a size ranging from 5500 to 6500 meshes, drying, collecting, depolymerizing, scattering, and adding composite modifying agents for surficial modification, wherein the composite modifying agents at least comprise titanate coupling agents, ethyl laurate and sodium dodecyl sulfate. The invention further provides composite filler prepared by the composite flame-retardant filler preparation method, and the prepared composite filler is applicable to ABS (acrylonitrile butadiene styrene) shell filling and has a flame retarding function.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of modified fillers, in particular to a method for preparing composite flame-retardant fillers and products thereof. [0003] 【Background technique】 [0004] With the improvement of people's quality of life, household appliances have also penetrated into thousands of households. While bringing people a happy life, household appliances have also brought some disasters. Fires on the plastic shells of household appliances have become the main culprit of family fires, and fires are threatening People's lives and property safety. At present, many of our home appliance plastic casings are made of ABS resin (that is, Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene resin,) products, and most of them will add barium sulfate to improve their overall performance. Barium sulfate, that is barite powder, is a naturally formed white inorganic salt. Because of its strong chemical inertness, good stability, a...
