Problems solved by technology

All items in the workshop will be seriously polluted, the packaging materials produced cannot be used, and the loss is huge. What is more serious is that the entire workshop space is polluted, it is difficult to clean and disinfect, and the manufacturer will suffer huge losses.
In addition, the UV curing temperature is very high, which consumes a lot of energy.

Embodiment 1

[0018] raw material A

[0019] TDI 0.5moL,

[0020] HDI 0.5moL;

[0021] raw material B

[0022]

[0023] raw material C

[0024] Polytetrahydrofuran 0.15moL;

[0025] The preparation method is as follows:

[0026] Put the raw material A and the catalyst (organotin, the addition amount is 0.1-3% of the total feeding amount) into the kettle, start the stirring, and let in dry nitrogen. The mixture of raw material B and raw material C is added dropwise, and the reaction is kept at 40-75°C for 1.5-5 hours until the NCO reaction is complete and the reaction ends, and the resin of the present invention is obtained.

Embodiment 2

[0028] raw material A

[0029] TDI 0.3moL,

[0030] HDI 0.3moL,

[0031] IPDI 0.2moL,

[0032] MDI 0.2moL,

[0033] raw material B

[0034]

[0035] raw material C

[0036] Polytetramethylene ether glycol 0.2moL;

[0037] The preparation method is as follows:

[0038] Put the raw material A and the catalyst (organotin, the addition amount is 0.1-0.3% of the total feeding amount) into the kettle, start stirring, feed dry nitrogen, and drop the mixture of raw material B and raw material C. Insulate and react at 40-75° C. for 1.5-5 hours until the NCO reaction is complete and the end point of the reaction is obtained to obtain the resin of the present invention.

Embodiment 3

[0040] raw material A

[0041] IPDI 0.5moL,

[0042] MDI 0.5moL,

[0043] raw material B

[0044]

[0045] raw material C

[0046] Polytetrahydrofuran 0.2moL,

[0047] Polytetramethylene ether glycol 0.4moL;

[0048] The preparation method is as follows:

[0049] Put the raw material A and the catalyst (organotin, the addition amount is 0.1-0.3% of the total feeding amount) into the kettle, start stirring, feed dry nitrogen, and add the mixture of raw material A and raw material C dropwise. Insulate and react at 40-75° C. for 1.5-5 hours until the NCO reaction is complete and the end point of the reaction is obtained to obtain the resin of the present invention.

Abstract

The invention relates to a preparation method of an LED cold light solidified ink binder. The preparation method comprises the steps of feeding a raw material A and a catalyst (the adding amount of organic tin is 0.3%-3.0% of total feeding amount) into a kettle, starting to stir, introducing dry nitrogen, drowise adding a mxture of a raw material A and a raw material C, and carrying out thermal insulation reaction at 40-75 DEG C for 1.5-5 hours until reaching a reaction end point (the reaction of NCO groups is finished), so as to obtain resin provided by the invention. The resin has excellent reaction activity, strong adhesion force to processed BOPP, OPP, PET and NL films and good flexibility and scraping resistance and is applicable to the LED cold light solidified ink binder.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a method for synthesizing LED cold light curing resin. Background technique [0002] Photocurable resin, usually UV curable resin, commonly known as UV resin, is characterized by curing the resin with ultraviolet light. The ultraviolet lamp is a mercury vapor lamp. Mercury vapor is a highly toxic and harmful gas. During the application process, the mercury vapor ultraviolet lamp is damaged, and the mercury vapor will pollute all substrates in the entire production workshop. All items in the workshop will be seriously polluted, the packaging materials produced cannot be used, and the loss is huge. What is more serious is that the entire workshop space is polluted and it is difficult to clean and disinfect, and the manufacturer will suffer huge losses. In addition, the UV curing temperature is very high, which consumes a lot of energy. The technology of the invention ...
