Problems solved by technology

[0002] At present, the UV vacuum coating coating technology uses polyurethane acrylate as the main resin of the primer formula. Hardness, fast curing performance and good adhesion performance, but its high brittleness limits its dosage in the formula, so its dosage should not be too high; It is impossible to completely convert, so the amount of monofunctional reactive diluent in the formulation should not be too high, which will lead to excessive viscosity of the coating and inconvenient use
Generally speaking, the existing vacuum coating UV curing coatings generally have the disadvantages of low heat resistance, poor adhesion and poor weather resistance.

Abstract

The invention discloses heat resisting coating and a preparation method thereof. The heat resisting coating is prepared from the following raw materials in parts by weight: 1.5 to 3 parts of SDBS (sodium dodecyl benzene sulfonate), 3.2 to 5.5 parts of nekal, 1.5 to 2 parts of barium 2-ethylhexanoate, 8.5 to 10.6 parts of aralkyl phenol polyoxyethylene ether formaldehyde condensate, 2.5 to 3.4 parts of thickener, 2.3 to 3.5 parts of boride oleylamine, 4.5 to 7 parts of water, 3.4 to 5.6 parts of diethanolamine maleic anhydride complex ester and 0.07 to 0.12 parts of preservative. A formula disclosed by the invention is relatively environment-friendly, the aralkyl phenol polyoxyethylene ether formaldehyde condensate and a boride oleylamine diluted monomer are optimized, the adhesive property to a low surface tension substrate is improved, so that a new developed product has higher heat resistance and good weathering resistance, and has the applicability to various substrates, the anti-ultraviolet property and the stability of the coating are improved, the heat resistance, the adhesive force and the weather resistance are improved, the production cost is lowered, and the heat resisting coating and the preparation method are convenient to be popularized.

Description

technical field [0001] The invention relates to a coating, in particular to a heat-resistant coating and a preparation method thereof, and belongs to the field of coatings. Background technique [0002] At present, the ultraviolet vacuum coating coating technology uses polyurethane acrylate as the main resin of the primer formula. Its function is mainly to provide good flexibility and certain adhesion of the cured film. Hardness, fast curing performance and good adhesion performance, but its high brittleness limits its dosage in the formula, so its dosage should not be too high; It is impossible to completely convert, so the amount of monofunctional reactive diluent in the formula should not be too high, which will cause the paint to be too viscous and inconvenient to use. Generally speaking, the existing vacuum-coated UV-curable coatings generally have disadvantages such as low heat resistance, poor adhesion and poor weather resistance.
