(54) PRINT PAINT

one

The invention relates to printing inks and can be used in any printing method on various non-absorbent materials (zhert, nickel, aluminum, and other metals, colored and polymeric products). Known ink for printing 1 on non-absorbent materials including, weight,%:

Synthetic. (Condensation). Volatile phenol-formaldehyde resin 16-18 Epoxy resin 12-14 Solvent33-37 Pygmate and fillers 30-36 Hardener 1.5-2.5 However, this composition is characterized by low adhesion to polymeric materials (28.5 kgf / cm ), which excludes the possibility of using paint for printing on plastics, as well as for marking and coding radio components in plastic cases with inadequate resistance to temperature changes (from -60 to 155 s) and prolonged high temperature, which prevents the use of red for printing on products operating in conditions of high temperature and its differences.

The purpose of the invention is to increase the adhesion of the paint to the polyolefin resistance to temperature and the effect of high temperature.

The goal is achieved by the fact that paint for non-absorbent materials, including synthetic 10 condensation resin, dyeing

component, filler, solvent and hardener, as filler contains polyvinyl chloride with a particle size of 0.01-0.5 μm at 15, the following ratio of components, weight,%:

SolventExtra

It is established that when the particle size of highly dispersed polyvinyl chloride is 0.01-0.5 μm, the forces of intermolecular interaction between the particles and the film-forming paint are most significant. These forces, blocking film-forming active centers, promote relaxation (dissipation30) of internal stresses in the forming colorful film (which ensures high paint adhesion to polymeric materials 80-100 kgf / cm and high thermal strength properties (at 5000 hours) of the resulting colorful impression and durability to a temperature difference of -60 to,

E-epoxy, phenol-formaldehyde, alkyd, melamine-formaldehyde and any other synthetic resin meeting the requirements for film-forming, both separately and in various combinations, are used as a synthetic condensation g-resin.

As the solvent, organic or non-orthorine esters are used. hydrochloric monobasic or polybasic acids or mixtures thereof, high-boiling hydrocarbon solvents, oils or mixtures thereof, or any other solvent combined with a resin. Inorganic or organic dye components (pigments, dyes, lacquers) can be used in the paint.

Various compounds can be used as a hardener in the paint, which intensifies the film formation process. Preferably, amino and metal-containing substances are used, as well as organic and inorganic acids and their anhydrides.

Example 1. The paint composition, wt.%:

Epoxy resin 40.0 Phthalocyanine blue pigment15, 0

Phthalic acid dimethyl ester 15.0 Polyethylene polyamine 2.5 High dispersed polyvinyl chloride 27.5 is prepared as follows.

With vigorous stirring, the resin, solvent and highly dispersed polyvinyl chloride are mixed. The resulting paste is left for a day to mature. Next, it is thoroughly mixed with the pigment in a kneader with a Z-blade until a homogeneous batch is obtained. The finished batch is ground on a three-liter paint-spraying machine to obtain a degree of sweeping according to the Klyn method of 10-15 memes.
