ALKYL-URETHANE ENAMEL PAINT AND VARNISH COMPOSITION, METHOD OF PRODUCING ALKYD-URETHANE ENAMEL WITH DIFFERENT TONES AND ALKYD-URETHANE ENAMEL MANUFACTURING COMPLEX Russian patent published in 2009 - IPC C09D167/08 C09D175/04 C09D7/12 C09D7/14 C08G63/49 

FIELD: chemistry.

SUBSTANCE: group of invention relates to production of paint and varnish compositions such as enamel, and specifically to production of alkyd-urethane enamel with different colour spectrum, which can be used for protective-decorative coating various types of surfaces. The paint and varnish alkyd-urethane enamel composition contains a combination of at least one alkyd varnish and at least one alkyd-urethane varnish, a pigment component, which is necessary for forming the colour of the enamel, at least one organic solvent, a dispersing agent, a drier and other auxiliary target additives, including at least one rheological additive, anti-film additive, anti-crater additive. The method of producing alkyd-urethane enamel with different colours involves the following stages: possible preparation of separate liquid and granular components, and their batching in accordance with the formulation and consumption rates for the produced amount of enamel, preparation of intermediate products, two-step dispersion, setting "type", step-by-step control. Manufacturing complex for producing alkyd-urethane enamel in form of suspension, containing colouring pigments in a mixture of organic varnish, solvent, lapping compound and target additives, consists of posts which form a hydraulic system fitted with process pipe-lines, where posts are linked with each other according to operations producing the said suspensions and include a post for storing initial dry and liquid components, a post for batching and weighing said components, a post for mixing the components, a dispersing post, a post for setting "type" of the enamel and a post for packing final enamel product.

EFFECT: obtaining alkyd-urethane enamel with good physical and chemical characteristics, which does not flake during storage and does not form surface film and residue.
