Abstract
The present invention relates to lacquer-type painting materials and more particularly to zinc-containing formulations used as a protection against corrosion on metallic structures, buildings, pipes or articles. This invention relates more precisely to an anti-corrosion composition for the protection of metals, wherein said composition contains zinc powder as well as an ethylsilicate binder comprising ethylic alcohol, ethylsilicate, polyvinylbutyral, water and orthophosphoric acid. The zinc powder consists of particles, wherein the weight percent of particles smaller than 10 νm does not exceed 65, while that of particles larger than 20 νm does not exceed 15. This binder is characterised by the new proportions of its principal components, i.e.: ethylic alcohol/water: 10.5-15.3; ethylsilicate/water: 1.7-2.4 (relative to the weight). This invention also relates to a method for preparing the binder, wherein said method comprises dissolving the polyvinylbutyral in a portion of the alcohol, mixing the quantity of alcohol remaining with the orthophosphoric acid and the water, mixing together the two alcohol-based solutions thus obtained and finally adding the ethylsilicate to this mixture. This invention may be used to increase the corrosion resistance of a zinc-compounded coating up to 2000 hours in conditions such as a saline-mist chamber. The adhesive durability may also be increased from 8 to 12 months, while the durability of a freshly prepared composition is enhanced from 10 to 24 hours. This invention is particularly efficient in anti-corrosion applications on large metallic structures designed for extended use such as power-line supports, bridges, hydraulic structures, tanks for petroleum products, etc. This composition may be applied in situ and the coating may be repaired by applying a layer of said composition on the damaged sections.

In the process of obtaining ethyl silicate binder, two basic reactions proceed: hydrolysis and condensation. Depending on the values of Α and B in the binder, either hydrolysis products or condensation products are available. With Α = 7C8 and B = 1, 2 nd 1, 3 (π ο ο ο смеси с)), the quantity of water in the mixture is sufficient for a more complete flow of water at the initial stage of in- vestment. Длинные As a result, long, suitable chains are formed, the ideal is the consolidation of molecules and a highly viscous solution is obtained, which is close to k-shaped. A good binder has a small detergent that is easily transferred to a gel that is not suitable for use. The storage period of such a binder does not increase for 6-7 months, the business life of the companies is no more than 8 hours.

Reducing the particle size of more than 10 microns and the practical exclusion of fractions of more than 20 microns ensures a stable increase in the security of the employees An increase in the ratio of alcohol / water and ethylsilicate / water in the binder shifts the equilibrium of the hydrolysis reactions — the condensation in the hydrolysis state. With this, the formation of long, large chains is reduced, large particles are not formed, the result is a lower viscosity, which results in less than 12 months.

It shows the data given, both for значения Α values that are higher than 15.3, and B, which is higher than 2.4, adhesion is worse (higher than 1 point). The reason is a decrease in the film-generating capacity of the equipment. Investigations of hydrolysis processes and the development of condensation processes in the binder do not result in a significant increase in the risk of absorption.
