The invention discloses a preparation method of building glue. The preparation method is: under the condition of water bath, adding chopped fibers, calcium nitrate tetrahydrate and zinc nitrate hexahydrate to a certain amount of water, stirring to uniformity, then adding glutinous rice powder, xanthan gum, polyethylene glycol, sodium ethylenediamine tetraacetate, sodium dodecyl sulfate and urea, stirring for a period of time, dropping a certain mass concentration. Solution A was obtained by adjusting the pH value to alkalinity of sodium hydroxide solution. Secondly, solution A was transferred to the hydrothermal reactor, and the temperature was controlled for a period of time. A certain concentration of hydrochloric acid was added to adjust the pH value to neutrality and cooling to prepare solution B. Finally, under the condition of water bath, glutinous rice powder was added to solution B, stirring and grinding for a period of time, and building glue C was prepared. The building adhesive has the advantages of strong bonding, environmental protection, anti-ultraviolet and durable weathering. It can be used in wallpaper, plastic runway, building plate and other fields.
【技术实现步骤摘要】
一种建筑胶的制备方法
本专利技术属于环保建筑材料的制备技术,特别是一种建筑胶的制备方法。
技术介绍
建筑胶在建材领域具有广泛的应用,例如:壁纸的粘贴、地板中木屑的粘结、塑胶跑道中橡胶颗粒的粘结等。常规使用的建筑胶中,或多或少残留微量甲醛,甲醛具有长期缓慢散发的特点,危害性极大,例如:引起白血病、胎儿畸形、呼吸道疾病甚至癌症等。开发不含甲醛的建筑胶已经在环保建筑材料领域引起了广泛的研究兴趣,例如:CN107652923A报道了一种无醛建筑胶及其制备方法。糯米胶是一种天然胶,具有环保、粘结性好等优点,但也存在易变质、发霉、抗紫外线差、耐久耐候性差等缺陷,对于糯米胶的改性也获得了越来越多的重视。因此,开发具有绿色环保、抗紫外线、耐久耐候、成本低廉的建筑胶已经成为了一种迫切需求。
