Embodiment Construction

[0008] The formulations described in the present invention are percentages by weight.

[0009] The resin liquid component is composed of 15-20% PVC resin powder and 85-80% cyclohexanone. Put the formulated amount of cyclohexanone in the dissolving tank, and the dissolving tank is heated in a special water bath heating and dissolving device. Slowly add PVC resin powder while stirring. As the temperature continues to rise, the resin powder gradually dissolves. Heat and stir until it is transparent and completely dissolved.

[0010] The mixed solvent component is formed by mixing 55-58% xylene, 40% cyclohexanone and 5-2% dibutyl phthalate after thorough stirring.

[0011] Black pigment color paste is made of resin liquid 59%, carbon black 20%, light calcium carbonate 20%, triethanolamine 1%, and resin liquid is placed in the container, adds carbon black, light calcium carbonate under the situation of stirring, when After the solid powder is fully wetted, add triethanolamine, and...

Abstract

The invention relates to a PVC paint having a coating manner of a dip coating or a sprinkle coating. The PVC paint comprises the following four components by weight percent: 50-55% of resin liquid, 15-10% of liquid organic glass, 2%-1% of pigment mill base and 33-34% of a mixed solvent, wherein the resin liquid comprises 15-20% of PVC resin powder and 85-80% of cyclohexanone; the pigment mill base is red and black oil-soluble pigments and the mixed solvent comprises 55-58% of xylene, 40% of cyclohexanone and 5-2% of dibutyl phthalate. Each component is fed in proportion. The coating method can adopt the dip coating, namely, a product is immersed into the paint, lifted and suspended, during draining, the paint forms a film while downwards flowing, the color of the product is different along with the amounts of paint remained in the surface of the product and a three-dimensional visual effect which naturally changes along with the change of patterns is given; the coating method can also adopt the sprinkle coating, namely, the product is positioned in a rack, to-be-coated one side of the product is not needed to downwards face, the paint is sprinkled from the top of the product and the same coating effect as that of the dip coating is achieved.

Description

Technical field: [0001] The invention relates to a PVC coating, in particular to a coating used for surface coating of recycled or new PVC products, and the coating form is dip coating. Background technique: [0002] With the widespread utilization of renewable resources, there are many types of PVC plastic products produced from recycled PVC raw materials. However, due to the various colors of recycled PVC, and the impurities and dust mixed in, the produced products have ugly colors and dull surfaces, which are difficult for consumers to accept. Then there is a full-covering PVC coating, which makes the recycled PVC raw material products covered with new clothes of various colors, giving consumers a brand-new consumption vision. Nevertheless, the biggest limitation of full-coverage spray paint is that the color is monotonous and flat. Except for color registration, it is difficult to show more than two kinds of differentiated colors on the same product, and even change wit...
