Embodiment Construction

[0020] The specific implementation steps of the present invention are as follows figure 1 shown.

[0021] The steps of the preparation method of a high-gloss anti-shock wet ultra-fine powder special for household appliance casing materials in this embodiment are as follows:

[0022] (1) Washing and crushing of raw ore

[0023] The industrial raw ore calcite and the industrial raw ore barite are coarsely crushed, cleaned, and crushed once to obtain raw ore with a diameter of 5-10 cm.

[0024] (2) Secondary crushing. The cleaned and crushed calcite and barite raw ore are mixed according to the mass ratio of 30-70:1, put into the silo for secondary crushing, and materials with a diameter of 5-10mm are obtained after secondary crushing.

[0025] (3) Dry grinding. The secondary crushed material is transported to the 198-type ring roller mill for dry grinding by belt, and grinding aid is added at the entrance of the ring roller mill, and the composite powder of 400 mesh to 600 m...

Abstract

A method for preparing high-gloss anti-shock wet ultra-fine powder special for home appliance casing materials. In the method, high-quality calcite raw ore and high-quality barite raw ore are mixed in a certain proportion, crushed, added grinding aids and dry-milled, and then added a dispersant Prepare a high-solid composite powder slurry; after the high-solid composite powder slurry is compounded with low-solid titanium dioxide slurry, it is then subjected to high-speed stirring and constant temperature grinding to obtain a 6,000-mesh composite slurry; then dried, collected After depolymerization and dispersion, the surface is modified by a compound modifier; then an impact modifier is added and stirred at a high speed to obtain a high-gloss and impact-resistant wet-process ultrafine powder. Due to the adoption of the above steps, the product prepared by the method of the invention has the advantages of high refractive index, fine fineness, high degree of surface activation, good impact resistance and the like.

Description

technical field [0001] The invention relates to a preparation method of a special high-gloss anti-scouring ultrafine powder for housing materials of household appliances, which belongs to the technical field of fine chemicals. Background technique [0002] Wet ultra-fine calcium carbonate is a new calcium carbonate production process that has developed rapidly in China in recent years. It can realize ultra-fine processing in the field of calcium carbonate deep processing, and realize the processing fineness of heavy calcium carbonate from less than 2500 mesh to 3000 mesh. Mesh - 8000 Mesh Development. Due to its unique small size effect, ultra-fine calcium carbonate has a series of advantages such as good dispersion and good processing fluidity, it is widely used in plastic films, wires and cables, shoe materials, plastic pipe fittings and other fields. [0003] With the improvement of residents' living standards, the use of household appliances is becoming wider and wider,...
