Problems solved by technology

Since thermoplastic acrylic resins are sensitive to temperature changes, when the ambient temperature of use or storage is too high, they tend to become too soft, and when the ambient temperature of use or storage is too low, they tend to become brittle. Therefore, as the seasons change, Generally, a certain amount of high boiling point solvent is added to the water transfer printing cover oil to adjust its flexibility, but the high boiling point solvent is prone to migration and volatilization, making the water transfer printing cover oil unstable. Great inconvenience in production and use

Abstract

The invention discloses four-season universal water transfer printing cover oil. The four-season universal water transfer printing cover oil is prepared from the following raw materials in parts by mass: 40-50 parts of thermoplastic acrylic resin, 0.1-0.5 part of a defoaming agent, 0.1-0.5 part of a thickening thixotropic agent, 30-40 parts of a solvent and 3-4 parts of a macromolecular polyesterplasticizer. The four-season universal water transfer printing cover oil is stable in mechanical property, the tensile strength and elongation of the cover oil do not fluctuate greatly along with changes of storage time and temperature, the low-temperature brittleness of the cover oil is improved, the using effect of the cover oil at different environment temperatures is effectively improved, andpracticability is high.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a four-season universal water transfer printing cover oil and a preparation method thereof. Background technique [0002] Water transfer printing cover oil is mainly used to fix the pattern on the water transfer printing paper, so that the pattern can be transferred to ceramics. At present, most of the water transfer cover oils on the market are composed of thermoplastic acrylic resins, solvents and additives. Since thermoplastic acrylic resins are sensitive to temperature changes, when the ambient temperature of use or storage is too high, they tend to become too soft, and when the ambient temperature of use or storage is too low, they tend to become brittle. Therefore, as the seasons change, Generally, a certain amount of high boiling point solvent is added to the water transfer printing cover oil to adjust its flexibility, but the high boiling point solvent is prone to ...
