SU555208A1 - The method of obtaining coatings - Google Patents

Description

The invention relates to the construction industry, namely, to methods of coating proliferation and can be used in roofing, waterproofing and other similar works.

Methods are known for producing coatings by laying a web of material on a substrate previously coated with an adhesive composition, for example, with mastic, followed by rolling,

There is also known a method for producing potions from mastic roll materials with coarse-grained dressing on cement foundations, which consists in applying bitumen masks to the coiled material, laying the material with stoppers on the primed base, and gluing the coating during heating of the mastic and rolling. However, the known method has significant drawbacks, the main ones being the complexity of the laying process and the insufficient quality of the coatings.

The purpose of the invention is to simplify the process.

This is achieved by heating the coiled material to a temperature that relieves internal elastic stresses, lay them down onto the freshly laid cement base until it begins to harden and roll down while simultaneously vibrating.

The method of producing coatings is that a roll of material, for example, brand-grade felt, is rolled out and heated to a temperature of 40-60 ° C with simultaneous cleaning from. sandy part of the sandy dressing. Then, prepared rolled material, in which there are no internal stresses, is laid on the newly formed reinforced concrete panel with sanding to the smooth surface of the base. Combining the coiled material with a cement base is realized during the movement of a pad vibrator, which creates a pressure of 15 g / cm with vibration parameters: amplitude 0.5 mm, frequency 50 Hz, moving at a speed of 5-10 m / s. As a result of applying vibrations to the OHUbtx impact on the base through the rolled material, the cement paste is squeezed out, which is an adhesive, and its adhesive properties are not limited to mechanical adhesion and change in viscosity, but increase due to the suction of the hydrophobic rolled material caused by the vacuum developing base hardening process. The actual process of hardening the base after laying the roll material on it proceeds in the usual way. Warming up, which was used in thermal curing, does not affect the quality. Since the molded products with the rolled material laid on them for some time, they are kept in the steaming chamber until it is filled and the temperature rises in it, at which time the initial dough, which glues the base and the rolled material, stages of the hardening process, as a result of which crystalline structures develop and the strength of gluing is sufficient. The method can also be implemented in cases where the subsequent heating of the products is not performed. The proposed method makes it possible to arrange blood, waterproofing and other coatings as in the manufacture of parts in factory conditions as in the erection of buildings and structures, to reduce their cost and improve quality. Experiments conducted in the research laboratory of physico-chemical mechanics of materials and technological processes showed that the consolidation of the ruberoid sticker on newly formed products is not less than 99%, and the strength of the coatings by tearing exceeds 1 kg / cm. The invention of the method for producing coatings of mastic roll materials with coarse-grained dressing on cement foundations, characterized in that, in order to simplify the technological process, the coiled material is heated to a temperature that relieves elastic stresses, is laid by sprinkling on a freshly laid base before it begins to harden and roll with simultaneous vibration exposure.
