Description

The known method is obtained by elec | ) oizo / 1 ionic mother / ia by casting products from a fine suspension of mica (its waste).

The peculiarity of the on-stratum method, which provides an increase in the mechanical strength and the improvement of the electrical characteristics of this electro-insulating material, is that the products before processing are treated with an orthosilicic acid hydrolyzate. During hydrolysis, esters of this kieli are planted on the surface of mica by gel of orthosilicic acid without destroying the mica crystal lattice, as the ego takes place during wet treatments of mica in the lyes and cis / 1otn.5Xx solutions.

The active gel of orthosilicic acid landed on the mica surface of mica reacts to further processing with hydroxyl hydrated mica to form siloxane bonds. This method contributes to the creation of materials with a high mechanical strength and, most importantly, it resists mechanical mecha- nism | strength at. action HIGH tel. Since the heating of materials obtained from hydrate-treated mica and gel of orthosilicic acid leads to a rise in the mechanical indices as a result of the further reaction of the hydroxide rpytui, j-hydrated mica and gel of the orthosilicic acid.lot.

In the chemical OTHOHRMUIH, the introduction of an orthocremeic acid gel into hydrated mica leads to an increase in the SiO2 content in the material obtained by the method described above, which is a matter of fact. The electrical characteristics are due to their resistance to the action of water and the electrical properties, since n, e.1-point elements of mica are enveloped with ortho-silicon acid gel. The alkaline elements that make up the mica bind to the active hydroxyl groups of the orthocrempic acid gel, and the ability to leach them with water is drastically reduced. This explains the increased water resistance and electrical properties of the electrically insulated material thus obtained.

The introduction of a suspension of orthosilicic acid ethyl ester into a waterborne or waterborne resin suspension increases the mechanical strength of the material many times, which opens up new possibilities for obtaining 1 micronite paper without using organic binding compounds and other organic components.
