【正文】 PH 等 性能測試，以確保反應(yīng)正確進(jìn)行，得到合格的環(huán)氧順丁烯酸酯 EA 及環(huán)氧改性丙烯酸樹脂 。 噴涂，烘烤制得漆膜，測定其硬 度、附著力、耐水煮性及耐堿性等性能，以此研究環(huán)氧樹脂含量對水溶性改性丙烯酸樹脂涂料漆膜性能的影響 。 實(shí)驗(yàn)結(jié)果表明 的 環(huán)氧用量 對 環(huán)氧樹脂含量對水溶性改性丙烯酸樹脂涂料 的附著力和硬度影響不大，但可對其耐水煮及耐堿性造成明顯改變。 關(guān)鍵詞 環(huán)氧改性 、 水性丙烯酸樹脂 、 漆膜性能 For the modified epoxy resin waterbased resin coating film performance impact ABSTRACT This experiment select high epoxide value and low viscosity epoxy resin Der671 with carboxyl and double bond of malefic anhydride reaction made epoxy malefic acid ester EA, then a double bond in the EA resin and acryl ate double bond polymerization synthesis of epoxy modified acrylic resin. And the EA and epoxy modified acrylic resin solid content, viscosity, PH and other performance testing, to ensure that the correct reaction, get qualified epoxy malefic acid ester EA and epoxy modified acrylic resin. And resin materials for preparation of varnish, performance testing, make sure to get to the actual use of indicators. Spraying, baking paint film system, determination of the hardness, adhesion, water resistance and al kali resistance, such as performance, this research epoxy resin content on the influence of water soluble modified acrylic resin coatings film performance. The optimum formulation of epoxy modified acrylic resin. The experimental results show that the dosa ge of epoxy resin content in epoxy adhesion and hardness of the water soluble modified acrylic resin coating effect is not big, but can cause obvious change to the water resistance and alkali resistance. The appropriate formula can be obtained watersoluble, weathering resistance and mechanical properties are very good watersoluble epoxy modified acrylic resin coating.
