preparation example Construction

[0041] In one embodiment, the preparation method includes the following steps:

[0042] (1) take each component according to the raw material ratio of the special water-based transfer varnish for anti-theft doors;

[0043] (2) The water-based polyester resin and the water-based alkyd resin are mixed, and the pH regulator, cosolvent, and defoamer are added to continue stirring to obtain a premix;

[0044] (3) Mixing the premix and amino resin, adding the leveling agent and deionized water and continuing to stir to obtain a special water-based transfer varnish for security doors.

[0045] The above-mentioned preparation method is further explained below:

[0046] Preferably, in step (2), the stirring speed of the mixing process is 700-800r / min, and the stirring time is 3-5min, and in the step (3), the stirring speed of the mixing process is 900-1000r / min min, to ensure that there are no air bubbles in the coating system and that the coating system is dispersed evenly.

Abstract

The invention relates to the technical field of paint, and particularly discloses special waterborne transfer varnish for a security door and a preparation method of the special waterborne transfer varnish. The special waterborne transfer varnish is prepared from the following components in percentage by mass: 25 to 35 percent of waterborne polyester resin, 8 to 12 percent of waterborne alkyd resin, 10 to 16.5 percent of amino resin, 1.5 to 2.5 percent of pH adjusting agent, 13 to 17 percent of co-solvent, 0.2 to 0.4 percent of defoaming agent, 0.2 to 0.5 percent of flatting agent, and 25 to 40 percent of deionized water. According to the special waterborne transfer varnish for the security door, the waterborne polyester resin is mixed with the waterborne alkyd resin and then cross-linkedwith the amino resin, so that the paint is excellent in heat storage stability and lower in VOC content, and a paint film is better in hardness, salt and alkali resistance, mist resistance, weather resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special water-based transfer varnish for anti-theft doors and a preparation method thereof. Background technique [0002] As the first threshold of home security, anti-theft door has the highest utilization rate in home security products. The full name of anti-theft door is "anti-theft safety door". Since the first door came out in the 1990s, the demand has grown at an annual rate of 13.9%. The demand of the door industry is 170 million square meters per year, and the materials have developed from iron doors, steel doors, aluminum alloy doors to stainless steel doors and copper doors; in appearance, from the first generation of ordinary doors to European doors and wide side doors , the sixth generation of decorative doors, continuous innovation in terms of lines, surfaces, and the whole. [0003] Most end users in the domestic market prefer wood grain effects. The surface co...
