Embodiment 1

[0032] The preparation method of the powder coating for the surface treatment of thermal transfer metal substrates, the steps include:

[0033] (1) 57 parts by weight of polyester resin SJ4E, 5.0 parts by weight of triglycidyl isocyanurate, 1.0 parts by weight of acrylate copolymer, 0.6 parts by weight of polytetrafluorowax, 0.4 parts by weight of benzoin, and 8 parts by weight of titanium dioxide 25 parts by weight of high-gloss barium sulfate were mixed with a mixer for 8 minutes; wherein, the oil absorption of high-gloss barium sulfate was 17g / 100g; polyester resin SJ4E was added in 3 times, adding 20 parts by weight for the first time and adding 20 parts by weight for the second time , adding 17 parts by weight for the third time;

[0034] (2) A twin-screw extruder is used for melt extrusion, wherein the temperature in zone I of the extruder is 110° C., and the temperature in zone II of the extruder is 115° C.;

[0035] (3) cooling and compressing, crushing to obtain the ...

experiment example

[0041] The powder coating product obtained in Example 1 above is sprayed, and the spraying step includes: using a high-voltage electrostatic spraying method to spray the powder coating product obtained in Example 1 on the surface of an aluminum profile to obtain a workpiece; placing the workpiece at 210° C. for 10 minutes and baking it to make The workpiece is completely solidified; after the workpiece is cooled, apply thermal transfer glue evenly on the workpiece, then cover the wood grain transfer paper and wipe it flat; put the processed workpiece into the baking condition of 170°C Bake for 15 minutes; after cooling, tear off the transfer paper to obtain a coating film of wood grain powder coating.

[0042] Compared with the product preparation method, the steps include:

[0043] (1) 50 parts by weight of polyester resin SJ4E, 7.0 parts by weight of triglycidyl isocyanurate, 3.0 parts by weight of acrylate copolymer, 0.5 parts by weight of polytetrafluorowax and 0.3 parts b...

Abstract

The invention discloses a powder coating for surface treatment of a thermal transfer printing metal substrate and a preparation method thereof. The powder coating comprises 52 to 60 parts by weight ofa polyester resin, 5.3 to 7.7 parts by weight of an auxiliary agent, 5 to 10 parts by weight of a pigment, and 20 to 32 parts by weight of a filling material, wherein the auxiliary agent comprises 4.5 to 5.3 parts by weight of a curing agent, 0.8 to 1.2 parts by weight of a leveling agent, 0 .3 to 0.8 part by weight of a transfer printing agent and 0.2 to 0.4 part by weight of a degassing agent.The powder coating obtained by using the preparation method provided by the invention has the following advantages: the rate of curing is high; the curing hardness of a coating film formed from the powder coating is high and can achieve 2H; the process of separating transfer printing paper in the process of transfer printing can be easily implemented; the rate of separation is up to 98%; the construction speed and finished product effects of a thermal transfer printing process are improved; and problems like difficult tearing of paper in the process of paper tearing in the prior art are overcome.

Description

technical field [0001] The invention belongs to the technical field of powder coatings, in particular to a powder coating used for surface treatment of thermal transfer metal substrates and a preparation method thereof. Background technique [0002] Considering factors such as environmental protection and economy, powder coating spraying is often used in the treatment of aluminum alloy doors and windows, anti-theft doors, fire doors, steel and wood furniture, and metal decorative parts. The spraying effect of powder spraying is superior to the painting process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also lower than that of spraying paint with the same effect. [0003] To further enhance the aesthetics of the above materials, thermal transfer printing is often required on top of the powder coating layer. The powder coating thermal transfer process uses special thermal transfer paper, which is directly pasted on...
