Formaldehyde scavenger agent can effectively control formaldehyde emissions from wood-based panels, but the existing formaldehyde scavenger agent can only work in the short term. For the purpose of long-term control of formaldehyde emissions from wood-based panels, microencapsulation of formaldehyde scavenger agent was synthesized in this paper. The effect of the emulsifying agent and the core to shell ratio on the microcapsules' morphology and formaldehyde degradation efficiency was investigated. The results showed that microcapsules of optimum morphology with high degradation efficiency can be obtained under the condition of 1% of the sodium dodecyl sulfate emulsifier, 3% of the shell solution, and a core to shell ratio of 1:3 with 1000 r/min stirring speed. The loading ratio and efficiency of the microcapsules achieved 36.25% and 8.05% respectively. Compared with control panels, the formaldehyde released from veneered panels treated with microcapsules was 39.7% and 41.4% lower in short-term and long-term emissions.

甲醛清除剂可以有效控制人造板甲醛释放量，但现有的甲醛清除剂只能在短期内起作用。为了长期控制人造板甲醛释放量，本文合成了甲醛清除剂的微囊化工艺。研究了乳化剂和核壳比对微胶囊形态和甲醛降解效率的影响。结果表明，在1000 r / min的条件下，以十二烷基硫酸钠乳化剂的1％，壳溶液的3％，核壳比为1：3的条件下，可获得具有最佳降解效率的最佳形貌的微胶囊。搅拌速度。微胶囊的负载率和效率分别达到36.25％和8。分别为05％。与对照组相比，经微胶囊处理的贴面板的甲醛释放的甲醛短期和长期排放降低了39.7％和41.4％。
