Bamboo wood modifier as well as preparation method and application thereof
The invention discloses a bamboo wood modifier as well as a preparation method and application thereof. The modifier is prepared from the following raw materials: a silicon-aluminum raw material, an activator and an auxiliary agent, the activator is a silicate; the silicate comprises at least one of sodium silicate and potassium silicate; the modulus of the activator is 1.0 to 1.5. According to the bamboo wood modifier, the geopolymer and the nano silicon dioxide are compounded, the inorganic polymer is formed after the geopolymer is gelated and cured in bamboo wood, and cell cavities are filled and covered with the inorganic polymer, so that modification of the bamboo wood is achieved; the nano silicon dioxide is used as a reaction core, the surface adsorbs a geopolymer monomer, and a geopolymer gel reaction is accelerated; meanwhile, polymerization reaction with a geopolymer monomer is directly carried out to fill a wood cavity; the bamboo wood modification effect is further improved.
本发明公开了一种竹木改性剂及其制备方法与应用，该改性剂包括以下制备原料：硅铝原料、激发剂和助剂；所述激发剂硅酸盐；所述硅酸盐包括硅酸钠和硅酸钾中的至少一种；所述激发剂的模数为1.0～1.5。本发明的竹木改性剂利用地质聚合物和纳米二氧化硅的复配，利用地质聚合物在竹木内部凝胶、固化后形成无机聚合物，利用无机聚合物对细胞腔的填充和覆盖，实现对竹木的改性；纳米二氧化硅作为反应内核，表面吸附地质聚合物单体，加速地质聚合物凝胶反应；同时直接与地质聚合物单体发生聚合反应，填充木材腔体；进一步提升竹木改性的效果。
