Embodiment 1
[0051] A transparent solid leveling agent, its raw material components and parts by weight are as follows:
[0052]
[0053] When synthesizing transparent solid leveling agent, solvent xylene is used. The solvent is indispensable for the solution polymerization process. It provides liquid phase reaction conditions, but does not participate in the reaction. The dosage is 950L+50L.
[0054] A kind of synthetic method of transparent solid leveling agent as mentioned above, the steps are as follows:
[0055] (1) In the reaction still equipped with agitator, fractionation column (vertical tower), horizontal tower, phase separation tank and nitrogen inlet, pump 950L of xylene solvent (accounting for 95% of the total amount of solvent, remaining 5% with 10% mixing of the initiator for the final addition), fill nitrogen protection from the bottom of the reaction kettle, start the agitator, and slowly heat up, within 30 to 60 minutes, the solvent in the kettle is heated to 120±3°C (...
Embodiment 2
[0062] A transparent solid leveling agent, its raw material components and parts by weight are as follows:
[0063]
[0064] When synthesizing transparent solid leveling agent, solvent xylene is used. The solvent is indispensable for the solution polymerization process. It provides liquid phase reaction conditions, but does not participate in the reaction. The dosage is 950L+50L.
[0065] A kind of synthetic method of transparent solid leveling agent as mentioned above, the steps are as follows:
[0066] ⑴The reaction kettle is pumped in the solvent according to the total mass of raw materials:solvent kg:L ratio of 1:0.8~0.95 under vacuum state, fill the reaction kettle with nitrogen protection, start the agitator, and slowly within 30~60 minutes Raise the temperature to 80-125°C, maintain the temperature and fill the whole process with nitrogen protection;
[0067] (2) Mix 85% to 95% of the total initiator with all the hard monomers, functional monomers and molecular weig...
Embodiment 3
[0073] A transparent solid leveling agent, its raw material components and parts by weight are shown in Table 1:
[0074] Each component and content table of transparent solid leveling agent in table 1 embodiment 3
[0075]
[0076]
[0077] The synthetic method of a transparent solid leveling agent as described above is the same as in Example 2.
[0078] The indexes of a kind of transparent solid leveling agent of the present invention are as follows:
[0079]
[0080] It can be seen from the above indicators that the transparent solid leveling agent of the present invention complies with the enterprise standard Q / SYD2015-01.
