- MMA methyl methacrylate
- the polymer product was precipitated in the form of white particles.
- the reaction system was cooled, and the contents were dispersed in water to obtain an aqueous dispersion.
- the solid matter from the aqueous dispersion obtained was collected by filtration through a glass filter, washed, dewatered, and dried in vacuum at 80 ° C to give an MMA polymer (white color). Powder) 192g was obtained.
- the glass transition temperature (Tg) and the number average molecular weight (Mn) of the obtained MMA-based copolymer were measured by the methods described above. The results are shown in Table 2.
- the glass transition temperature of the MMA polymer was obtained in the same manner as in Synthesis Example 8 except that the composition of the monomer in Synthesis Example 8 was as shown in Table 2.
- Table 2 shows the number average molecular weight.
- HEMA Methacrylic acid 2 — Hydroxyethyl
- GMA Glycidyl methacrylate
- the crosslinkable functional group-containing VdF-based polymer synthesized in Synthesis Example 1 (60 g) and the MMA-based polymer synthesized in Synthesis Example 5 (40 g) were combined with a bus conidone.
- the mixture was melted and kneaded at 160 ° C for 5 minutes, extruded in a sheet form, pelletized, and a composite resin pellet was obtained.
- the MFR of the composite resin pellet measured at 130 ° C and a load of 2. lkg was 42.3 g / 10 minutes.
- the above composite resin pellets were ground at room temperature (20 ° C) for 5 minutes by Microno and Nammamil (manufactured by IKA), and then ground. Workability was investigated. The evaluation shall be performed on the obtained powder according to the following criteria.
- the obtained pellets on a heat press at 200 ° C to a thickness of lm.
- the transmittance of the sheet at 630 nm was measured, and the curing agent compatibility was evaluated from the transparency as follows.
- a powder coating composition was obtained in the same manner as in Example 9 except that the VdF-based polymer, the MMA-based polymer, and the curing agent were changed.
- the powder coating composition shown in Table 5 was applied to a 0.3 mm thick JIS2003 A714 chemical conversion aluminum plate using a corona-type powder coating gun (Onoda Cement Co., Ltd.). GX3300) was applied at a printing power of 60kV and immediately baked at 180 ° C for 20 minutes to obtain a coated product.
- Measurements are made using an eddy current film thickness meter EL10D (manufactured by SANKO ELECTRONICS LABORATORIES).
- thermosetting powder coating composition of the present invention which uses a composite resin that can be pulverized at room temperature and has excellent compatibility with various types of curing agents, the production of powder coatings is possible. However, it is possible to provide a coated material having excellent coating film properties.
