で表されるアミノアルキル基を有するアルキルアルコキシシラン、および(C)界面活性剤を含有する有機ケイ素化合物エマルションであって、アルキルアルコキシシラン(A)とアルキルアルコキシシラン(B)の割合が、重量比で1:0.2〜0.4であり、界面活性剤(C)の量がアルキルアルコキシシラン(A)とアルキルアルコキシシラン(B)の合計量の1〜20重量%である水系吸水防止材が、充分な撥水性、吸水防止性、遮塩性等の諸性能を基材に付与でき、さらに、激しい風雨にさらされたり、積雪地域において外壁が常に雪と接触している場合のように多孔性材料に圧力がかかる条件下においてもその性能を非常に長期間維持することのできることを見出し、本発明を完成した。 And (C) an organosilicon compound emulsion containing a surfactant , wherein the ratio of the alkylalkoxysilane (A) to the alkylalkoxysilane (B) is ratio 1: 0.2 to 0.4, an aqueous water amount of surfactant (C) is 1 to 20% by weight of the total amount of alkyl alkoxy silanes (a) and alkyl alkoxy silane (B) Prevention material can impart sufficient performance to the base material such as sufficient water repellency, water absorption prevention property, salt barrier property, and furthermore, when exposed to severe wind and rain, or when the outer wall is constantly in contact with snow in snowy areas As described above, it has been found that the performance of the porous material can be maintained for a very long period even under a condition in which pressure is applied to the porous material, and the present invention has been completed.

本発明の水系吸水防止材は、水および/または水に可溶な溶剤を用いて、固形分が2〜60重量%、好ましくは5〜30重量%の濃度に調製して使用できる。固形分が2重量%濃度未満の場合、水系吸水防止材本来の性能が発揮されないだけでなく、効果を奏すためには多量に塗布しなければならないので乾燥に時間を要し、好ましくない。また、固形分が60重量%濃度を超える場合、粘性が高く、また多孔性材料への浸透性が悪くなり、濡れ色が発生する傾向がある。 The water-based water absorption preventing material of the present invention can be used after adjusting the solid content to a concentration of 2 to 60% by weight, preferably 5 to 30% by weight using water and / or a solvent soluble in water. When the solid content is less than 2% by weight, not only the original performance of the water-based water-absorbing preventive material is not exhibited, but also a large amount of coating has to be applied in order to exhibit the effect. On the other hand, if the solid content exceeds 60% by weight, the viscosity tends to be high, the permeability to the porous material is deteriorated, and a wet color tends to occur.
