Environment Friendly Building Finishing Material Made Of Sericite And The Method Of Making it

摘要

The present invention relates to a method for producing a peridotite, which comprises admixing vinyl acetate, sericite and water at a weight ratio of 1: 3.0 to 4.0: 1.5 to 2.5, respectively, wherein the sericite has a particle size of 500 to 1,000 mesh, An ore analysis step including an analysis of a mineral component of the ore including the at least one element; A crushing and crushing step of crushing or crushing said raw material; A physical purification step of purifying the impurities by a physical method so that the content of the impurities is 1 to 5% by weight; A zeta potential measuring step of measuring a zeta potential after inserting a standard sample of each impurity mineral analyzed in the step of analyzing the nacreous into water; Selecting a first catcher having a charge opposite to that of the first reference sample in the standard sample and floating the first reference sample; And a first debarking step of removing the first impurity mineral suspended in the water by adding 0.01 to 0.2 part by weight of the raw light and the first catching agent to 100 parts by weight of the raw ore; Selecting a second catcher having a charge opposite to the zeta potential of the second reference sample among the standard samples and floating the second reference sample; And a second flotation step of floating the flocculant in the water to remove the second impurity mineral suspended in water and the selected second trapping agent in water to form a sericite, Friendly construction finishing material, which is excellent in porosity and strength, can block harmful electromagnetic waves, and has a very excellent self-washing effect, so that it can be used as an environmentally friendly architectural finishing material.
