Research into physical and chemical properties of two-component paintwork materials
One of the ways to obtain light-diffusing volume optical effect throughout a paintwork coating to improve furniture products and board appearance is to use incompatible polymers in a paintwork material, i.e. creation of multicomponent paint and varnish systems. So, to form a two-component binary system of a paintwork coating preserving its refraction index for each phase, it is proposed to introduce nitrate base of polyvinyl acetate aqueous dispersion that will result in creation of heterophase colloidal system. It is also known that nitrocellulose and polyvinyl acetate are compatible mutually-soluble polymers. In their presence, the dispergating of polyvinyl acetate aqueous dispersion in the nitrate base medium occurs. As a result of dispergating, the phase polymer globes (polyvinyl acetate dispersion) will be surrounded by hydrated films (nitrocellulose varnish). The process of paintwork coating hardening will take place due to evaporation of water molecules surrounding the phase polymer particles. Therefore, the so-called "crystallizing out" of polyvinyl acetate particles throughout the basic film-forming without their interaction with medium molecules is realized. It is supposed that this fact has to have an effect on the optical properties of the obtained coating as to creating the volume effect of light absorption preserving its initial physical and mechanical characteristics
