Abstract

Increased intensity of operation of construction infrastructure, unfavorable for quality repairs of natural and climatic conditions of Ukraine and a high probability of emergencies necessitate the need for domestic import-substituting structural composites for restoration work with regulated viability. The specifics of repair and restoration works - limited time, extreme temperature and humidity conditions, problems in ensuring full-fledged technology and others. - makes it necessary to develop PKM that take into account these features.

The authors state that such compositions can be developed on the basis of acrylic binders, mainly methyl methacrylate (MMA), polymer composite materials (PCM) based on which are characterized by high rates of strength, mechanical and physicochemical properties, as well as durability. comprehensive study of the influence of the conditions of formation of the polymer material (curing temperature) and prescription-technological factors (chemical modification of the binder, the method of introduction of benzoyl peroxide, etc.) on its strength. Effective means of increasing the latter have been identified.

To assess the effect of the studied modifiers on the change in the mobility of macromolecular chains by linear dilatometry, the glass transition temperatures Tc (° C) of PM polymer matrices were determined (decrease in glass transition temperature is usually associated with increased mobility of polymer chain segments).

It was found that among a number of studied modifiers - 3-methacryloxypropyltrimethoxylan (MPTMS), glycidyl methacrylate (GMA), dimethacrylate ether of triethylene glycol (TGM-3), hydroxypropyl methacrylate (GPMA) (the two most effective) (methacrylate).

The expediency of adjusting the content of PB and DMA to accelerate the set of strength at low positive and negative curing temperatures is shown. The optimal contents of PB and DMA have been established, which allow to reduce the time of reaching the minimum operational (40 MPa) and ultimate strength for bending of PM based on MMA.
