摘要： In order to prolong the usage of wood one needs to prevent the growth of rot and fungi. The most common substances used today are not environmentally friendly and they need to be replaced by more environmentally friendly options. Water glass or sodium silicate has been known for a long time having properties which give the wood resistance to rot and fungi and in addition also fire retardant properties. The present invention discloses a method for treatment of wood to improve the flame retardant properties and also the resistance to rot, fungus, mold and insects of a wooden material. The wood treatment method of the invention comprises the steps of providing a wooden material and providing water based formulation which is stable in room temperature or in temperatures ranging from 15-35 °C. The water based formulation of the invention consist essentially ofan alkali metal silicate, water and an insolubilization agent which is selected from an organic acid, an inorganic acid or an inorganic polyvalent ion, added in an amount lower than the amount of insolubilization agent needed for the formulation to reach the gelling point. Further the wood treatment method includes the steps of applying the water based formulation on the wooden material and drying the wooden material treated with said water based formulation at any given temperature in order to remove excess of water and also curing the dried wooden material at an elevated temperature in order to insolubilize the alkali metal silicate.

摘要翻译： 为了延长木材的使用量，需要防止腐烂和真菌的生长。 目前使用的最常见的物质不环保，需要更环保的替代品。 长期以来已知水玻璃或硅酸钠具有赋予木材抗腐和抗真菌以及另外还具有阻燃性能的性质。 本发明公开了一种处理木材以改善木质材料的阻燃性能以及对腐烂，霉菌，霉菌和昆虫的抵抗力的方法。 本发明的木材处理方法包括提供木质材料和提供在室温下或在15-35℃范围内稳定的水基制剂的步骤。 本发明的水基制剂基本上由碱金属硅酸盐，水和选自有机酸，无机酸或无机多价离子的不溶解剂组成，其加入量低于所需的不溶解剂的量 配方达到胶凝点。 此外，木材处理方法包括以下步骤：在木质材料上施用水基制剂，并且在任何给定温度下干燥用所述水基制剂处理过的木质材料，以除去过量的水，并且还在高架 温度以使碱金属硅酸盐不溶。
