Embodiment 1

[0021]

[0022] Preparation process: The raw materials are mixed according to a certain weight ratio, mixed evenly in an automatic mixer, and then extruded in a thermosetting twin-screw extruder. The extrusion temperature is 95°C in the first zone, 95°C in the second zone, and 100°C in the third zone. After cooling, it is pulverized by a pulverizer, electrostatically sprayed, and baked. Baking conditions were 130° C. for 10 minutes to obtain samples.

Embodiment 2

[0024]

[0025] The preparation process is the same as in Example 1.

Embodiment 3

[0027]

[0028] The preparation process is the same as in Example 1.

[0029] The samples of the three examples have been tested, and the curability, adhesion, hardness, wear resistance, and corrosion resistance have all reached the effect of normal powder coatings at 180°C for 15 minutes, and can be sprayed on the surface of medium density boards without damaging the medium density. plate.

Abstract

The invention belongs to the technical field of coatings, and particularly relates to a curing powder coating for a medium-density board and a preparation method thereof. The curing powder coating forthe medium-density board is prepared from the following raw materials in parts by weight: 35 to 45 parts of polyester resin, 35 to 45 parts of epoxy resin, 0.8 to 1.5 parts of a levelling agent, 0.5to 1 part of benzoin, 0.7 to 1.5 parts of a brightening agent, 15 to 25 parts of pigment and filler, and 0.3 to 0.6 part of a curing accelerator. The coating provided by the invention can effectivelyreplace paint, reduce the damage of volatile substances caused by a liquid coating, and is non-toxic and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a solidified powder coating for medium density boards and a preparation method thereof. Background technique [0002] The surface of decorative MDF usually needs to be sprayed with paint, but the paint is highly polluted, has volatile solvents and toxic gases, and is not environmentally friendly; in addition, the drying time is long and the efficiency is low. As a kind of solvent-free dry powder coating, powder coating has short drying time and no solvent gas pollution. -30 minutes. It cannot be used on MDF, so a low-temperature fast-curing powder coating can be used on MDF. Contents of the invention [0003] The purpose of the present invention is to provide a solidified powder coating for medium density boards, which can effectively replace paint, reduce the damage of volatile substances caused by liquid coatings, and is non-toxic and environmentally friendly; ...
