Novel water-repellent preservative agent and preparation method thereof
The invention relates to a raw material for building construction and in particular relates to a novel water-repellent preservative agent and a preparation method thereof. The preparation method of the novel water-repellent preservative agent comprises the following steps: weighing a fixed amount of natural coconut oil in ratio, putting the weighed natural coconut oil into a reaction kettle, heating to 150 DEG C and carrying out heat preservation for 20 minutes, successively adding superfine mineral powder, a surface active agent, diluted calcium hydroxide, a preservative slow releasing agent and a polycarboxylate high-performance water-reducing agent, continuously heating to a reaction temperature, reacting for 2 hours, adding water for diluting to specified concentration after reaction is completely finished, cooling and barrelling for later use. The invention aims at providing the novel water-repellent preservative agent which is convenient for construction and can be used for effectively reducing production cost and a preparation method of the novel water-repellent preservative agent.
