Description

醇酸树脂木器漆的制备方法
技术领域
本发明涉及一种醇酸树脂漆，具体的说，涉及醇酸树脂木器漆的制备方法。
背景技术
木材制品包括实木木材和人造板材(胶合板，中密度纤维板和刨花板)。用于木材制品的涂料统称为木器涂料，包括家具、门窗、地板、护墙板、日常生活用木器、木制乐器、体育用品、文具、玩具等所用涂料。以家具涂料为主。木器涂料按木器制造工艺分为2类，板材预涂料和木器成品涂装涂料。按涂料类型分为溶剂型涂料、水性涂料和无溶剂涂料。
醇酸树脂由多元醇、邻苯二甲酸酐和脂肪酸或油(甘油三脂肪酸酯)缩合聚合而成的油改性聚酯树脂。按脂肪酸(或油)分子中双键的数目及结构，可分为干性、半干性和非干性三类。干性醇酸树脂可在空气中固化；非干性醇酸树脂则要与氨基树脂混合，经加热才能固化。另外也可按所用脂肪酸(或油)或邻苯二甲酸酐的含量，分为短、中、长和极长四种油度的醇酸树脂。醇酸树脂固化成膜后，有光泽和韧性，附着力强，并具有良好的耐磨性、耐候性和绝缘性等。
醇酸木器漆，由醇酸树脂、催干剂、颜料、溶剂等调制而成的。具有较好的光泽和机械强度，能常温下干燥，耐候性较好，但耐水性较差，若在高温烘烤下，耐水性可显著提高。用于木器及室内家具表面的装饰。
发明内容
本发明的目的在于克服现有技术的不足，提供一种制备工艺简单，成本低并且应用广泛的醇酸树脂木器漆的制备方法。
为达到上述目的，本发明所采用的技术方案为：其原料含有如下重量份的组份：醇酸树脂25-37、抗氧剂2-5、对羟基苯甲酸甲酯3-5、肉豆寇酸异丙酯4-7、芳香族聚氨酯丙稀酸酯18-23、乙酰水杨酸2-3、N-羟甲基丙烯酰胺2-3、聚乙二醇3-4、偶联剂2-3、二硫化钼5-6、丙烯酸-2-羟基丙酯9-11、异丁基三油酸酰氧基钛酸酯4-7、乙基硫醇锡2-3、助剂3-5、二甲苯8-9、乙酸丁酯12-13；
(1)将对羟基苯甲酸甲酯、乙酰水杨酸、聚乙二醇、二硫化钼、助剂混合，加入到二甲苯、乙酸丁酯溶剂中，加热至120-130℃，反应3-4小时；
(2)将步骤(1)的物料冷却至70-85℃，加入肉豆寇酸异丙酯、丙烯酸-2-羟基丙酯、异丁基三油酸酰氧基钛酸酯，搅拌反应3-4小时；
(3)将步骤(2)的物料降温至50-65℃，加入其它剩余物料，搅拌反应40-60分钟后，冷却至室温，研磨成20-60μm浆料，即得。
醇酸树脂为长油度醇酸树脂，抗氧化剂为苯酚。
助剂由以下重量份的原料制成：粘土9-15、表儿茶素2-3、铁矿渣粉2-3、促进剂5-6、没食子酸丁酯2-3、苯基三乙氧基硅烷5-6、钼酸钠6-7、磁石1-2、苯乙酸钠1-2、柠檬酸异丁酯35-40、桐油3-4、二硼化钼1-2。
助剂的制备方法是：将粘土、磁石送入煅烧炉中在700-840℃下煅烧1-2小时取出，送入稀的盐酸溶液中浸泡2-5小时，过滤后滤渣，用清水洗净，烘干、研磨成500目粉体；所得粉体与其它剩余成分混合，加热至60-70℃，搅拌反应40-50分钟,冷却，研磨成浆料，即得。
一种醇酸树脂木器漆的制备方法：
(1)将对羟基苯甲酸甲酯、乙酰水杨酸、聚乙二醇、二硫化钼、助剂混合，加入到二甲苯、乙酸丁酯溶剂中，加热至125℃，反应3.5小时；
