A kind of production technology of ultra-thin synthetic mica powder for pearlescent material

Abstract

The invention discloses a production process of ultrathin synthetic mica powder for a pearl material. The production process comprises the following steps: preparing raw materials, preprocessing an intercalator, breaking and stripping by using high-pressure water, ultrasonically dispersing, microwave stripping mica sheets, crushing the stripped mica sheets by using a wheel grinding machine, gradually separating level by level, dehydrating, and drying. The mica sheets preprocessed by virtue of the high-pressure water sprayed out from a high-pressure water spray nozzle in an impacting manner arecombined with ultrasonic and microwave stripping, so that the mica sheets are layered and stripped and crushed into small blocks, compared with the traditional roller mill crushing way, the situationthat the mica sheets are crushed into powder is reduced, the waste of materials can be avoided, the dust of a crushing production workshop can be reduced, the crushing efficiency is higher, the scratches on the surface of the mica sheets when the mica sheets are crushed by a roller mill can be reduced, the quality of the mica sheets after being crushed by high-pressure water is better, and the mica sheets with smaller thickness can be obtained.

Description

technical field [0001] The invention relates to the technical field of mica powder tools, in particular to a production process of ultra-thin synthetic mica powder for pearlescent materials. Background technique [0002] As the requirements for matrix materials are getting higher and higher, natural mica can no longer fully meet the requirements, such as low calcination temperature, impure color, excessive thickness, etc., so it is imperative to prepare synthetic mica with excellent performance to replace natural mica . [0003] The thickness of synthetic mica powder is extremely important to the quality of pearlescent materials. The current synthetic mica is hard and brittle, that is, the flexibility is poor, generally less than 35% of the flexibility; Under the same particle size, the diameter-thickness ratio is small, the coating rate is low, the color saturation is low, and even no pearlescent effect is produced.
