Today despite the widespread introduction of electronic computer capabilities, paper is still the most widespread media and it’s known as a considerable production in the world that is constantly growing. Therefore, the problem of storing paper products is acutely actual. A considerable number of biocides were used to solve this problem, but either the complexity of the use of technology or the danger to the health of staff or the weakness of the drugs – none of the proposed ones did not solve the problem completely and even did not significantly advance its solution significantly. It is simpler and most definitely cheaper to use inorganic fibers, namely basalts, which are characterized by low chemical activity and do not promote the spread of different types of fungi of microorganisms are not subjected to insect mold, etc. During this work samples of paper processed by solutions of disinfection means with prolonged decontamination effect (“Gembar”, “Polidese”, “Metatin GT”) were studied on three types of papers (newspaper, packaging, mucalent). The action biocides was carried out on test cultures of microscopic fungi that were isolated from damaged documents. In addition, samples  of paper comprised of compositions of basalt and cellulose fibers, montmorillonite clay and sodium humate (SH) and salts of resin acids (SSRA). Aging samples were observed with indicators such the whiteness of materials the tensile strength (n.d.f.) – properties that are sensitive to the aging process. It is proved in the work that samples that have a composition mixture, basalt fibers almost to the same degree inhibit the spread of fungi and microorganisms as well  as typical disinfectants. It was interesting to investigate ether homoionic form montmorillonite which is part of compositions based on basalt and cellulose fibers affect the biocidal characteristic of materials. It has been proven that maximal firming of coagulatings systems happens up and adding of 10 % solution of sodium-ion to 15 % suspention of clay. Processing with salts of sodium has a positive impack of behavior of clay mineral of montmorillonite by stimulation creation of firmer composite materials that before. Therefore, the work proposed the material and composition mixture, which guarantees certain physics – mechanical properties and has a much simpler and cheaper technology of obtaining materials.
