为了实现上述目的，本发明提供一种防白蚁水性涂料，所述防白蚁水性涂料由下述重量百分比含量的组分构成：有机硅改性聚氨酯乳液50～80％，胺改性丙烯酸酯分散剂1～10％，防白蚁剂5～10％，消泡剂0.01～1％，水0.1～30％。
进一步的，所述防白蚁助剂为糊精、氯菊酯、功夫菊酯、联苯菊酯、胡椒丁醚、樟脑、吡虫、乙二醇丁醚制成。
所述防白蚁助剂质量份为糊精0.8～1.2份、氯菊酯0.02～0.04份、功夫菊酯0.01～0.03份、联苯菊酯0.01～0.03份、胡椒丁醚0.08～0.12份、樟脑0.02～0.04份、吡虫0.01～0.02份、乙二醇丁醚4～6份。
所述消泡剂为含气相二氧化硅的聚醚硅氧烷共聚物乳液。
为了实现上述目的，本发明还提供制备该防白蚁水性涂料的制备方法，该制备方法包括以下步骤：
S1分散处理、在有机硅改性聚氨酯乳液中加入胺改性丙烯酸酯分散剂，对搅拌罐进行搅拌，制成分散溶液；
S2消泡处理、在搅拌状态下，在所述分散溶液中加入防白蚁剂和消泡剂，进行搅拌，获得消泡溶液；
S3粘度调整、在所述消泡溶液中添加水，并继续搅拌，调整粘度。
进一步的，所述搅拌罐温度为40℃～60℃；所述搅拌的速度为200rpm～400rpm。
所述粘度值辊涂为600mPa·s～2000mPa·s，淋涂为200mPa·s～600mPa·s，喷涂为30mPa·s～100mPa·s。
上述用于木制品的防白蚁水性涂料的涂装方法，是将上述水性涂料采用辊涂、喷涂(包括静电喷涂)、真空喷涂、淋涂、浸涂、旋涂、抽涂等方式涂布于木制品上，经热风机固化后，再，在流水线上直接成品包装，得到具有防白蚁效果的木制品。
一种用于木制品的水性防白蚁涂料的涂装方法，具体包括下列步骤：
1)对木制品进行打磨；
2)将打磨完成的木制品进行除尘处理；
3)采用喷涂的方式对第2)步得到木制品上涂布获得的水性防白蚁涂料，经热风机烘干，两段式烘干，第一段烘干温度50℃，时间2min。第二段烘干温度80℃，时间3min。
相比于现有技术，本发明具有如下有益效果：
1、本发明的涂料中添加了有机硅改性聚氨酯乳液，使涂料具有附着力，易于涂覆至木材上，且使涂料具有耐冲击性、耐水性和耐化学性。
2、本发明的涂料中添加了防白蚁剂，防虫蚁效果好，且对人、宠物毒性低。
3、本发明的涂料可采用琨涂、喷涂、真空喷涂、淋涂、浸涂、旋涂、抽涂等方式涂布于木质材料上，适合快速生产，可有效提高生产效率。
