Problems solved by technology

However, for the coating of irregular decorative materials, most of them still need to be finished by manual spraying. The main reason is that the value attribute of Christmas decorations lies in the beauty (colorful), and the shaft coating surface oil on the market is temporarily not suitable for irregular decorations. Achieve the effect of regular coverage (the thickness of the coating film after coating is close, and the color depth is close)
[0003] The roller coating process is easy to operate and has high efficiency, so it is relatively common in the coating field. However, for special-shaped roller coating paints, it is not only necessary to overcome the centripetal force in the shaft coating process, but also to overcome the tension of the edges and corners of the special-shaped substrate, as well as its own Due to the influence of gravity, it is difficult to achieve complete rule coverage on special-shaped workpieces
[0004] The current status in the market: (1) manual spraying is often used for construction of special-shaped workpieces; (2) two processes are required for the roller coating process, first soaking colorless paint, drying and then thermal dyeing; (3) ) Roller paints on the market cannot cover and level well, and there will be white spots, color differences, and oil accumulation.

preparation example Construction

[0048] Another aspect of the present invention provides a kind of preparation method of fast leveling special-shaped roller coating vacuum coating surface oil, at least comprises the following steps:

[0049] (1) According to the formula, add acrylic resin, thixotropic agent, and additives into the dispersion tank, and mix evenly at a speed of 600-900r / s to obtain mixture A;

[0050] (2) adding a solvent to the mixture A for dilution to obtain a mixture B;

[0051] (3) The mixture B is obtained after filtering through a 100-mesh sieve.

Embodiment 1

[0055] On the one hand, this embodiment provides a fast leveling special-shaped roller coating vacuum coating surface oil, which includes 8.5 parts of water-soluble acrylic resin A, 8.5 parts of water-soluble acrylic resin B, and 3 parts of water-soluble epoxy acrylic resin. 2.5 parts of ammonia water, 0.5 parts of matting powder, 0.5 parts of talc powder, 0.6 parts of attapulgite, 0.4 parts of fumed silica, 4 parts of anti-white water, 12.5 parts of isopropanol, 46.5 parts of methanol, 12.5 parts of 120# solvent oil .

[0056] The water-soluble acrylic resin A is selected from Dongguan Longxing Synthetic Materials Co., Ltd., the model is 726; the water-soluble acrylic resin B is selected from Laiyang Jiaxin Packaging Material Factory, and the model is JX-505. Methanol is obtained by dispersing methanol at a weight ratio of 1:1; the water-soluble epoxy acrylic resin is selected from Shandong Dengnuo Chemical Co., Ltd., and the model is DN-L203; the attapulgite is selected from...

Abstract

The invention discloses a quick-leveling special-shaped roller coating vacuum coating surface oil and a preparation method thereof. The surface oil comprises the following raw materials by weight: 18-26 parts of acrylic resin, 65-74 parts of a solvent, 0.8-1.2 parts of a thixotropic agent, and 6-9 parts of an auxiliary agent. The raw materials are matched according to a specific proportion, the leveling problem is solved, chromatic aberration is eliminated, edges and corner angles are well covered, regular covering can be achieved on special-shaped workpieces, the prepared surface oil has excellent water resistance and adhesive force, meanwhile, the phenomenon of bottom agglomeration is avoided, and the surface oil is very suitable for coating of Christmas decorations. In addition, the preparation method is simple in process and convenient to operate.

Description

technical field [0001] The invention relates to the field of paints and coatings, in particular to a fast-leveling special-shaped roller coating vacuum coating surface oil and a preparation method thereof. Background technique [0002] With the development and progress of society, the coating process of circular decorative materials in the Christmas market at home and abroad has basically completed the change from manual spraying to machine shaft coating, which also greatly saves labor costs. However, for the coating of irregular decorative materials, most of them still need to be finished by manual spraying. The main reason is that the value attribute of Christmas decorations lies in the beauty (colorful), and the shaft coating surface oil on the market is temporarily not suitable for irregular decorations. Achieve the effect of regular coverage (the thickness of the coating film after coating is close, and the color depth is close). [0003] The roller coating process is ...
