Modified glass fiber powder enhanced polyurethane concrete and preparation method thereof
The invention discloses modified glass fiber powder enhanced polyurethane concrete, and belongs to the technical field of polyurethane concrete. The raw material components comprise a polyurethane adhesive and aggregate, wherein the polyurethane adhesive comprises 5-20wt% of siloxane coupling agent modified glass fiber powder; the preparation method of the siloxane coupling agent modified glass fiber powder comprises the following steps: dissolving a siloxane coupling agent in a water/ethanol mixed solution, and uniformly stirring; grinding glass fibers, sieving with a 1000-mesh sieve to obtain glass fiber powder, adding the glass fiber powder into the solution, and carrying out ultrasonic treatment; and after ultrasonic treatment, ethanol cleaning and drying are performed. Compared with pure polyurethane concrete, the polymer prepared by adding 15wt% of the glass fiber powder compound enhances the static elastic modulus by 38.7%, the breaking strength by 112.0%, the breaking modulus by 225.3% and the bonding strength by 44.9%.
本发明公开了一种改性玻璃纤维粉增强型聚氨酯混凝土，属于聚氨酯混凝土技术领域。其原料组分包括聚氨酯胶黏剂和骨料，所述聚氨酯胶黏剂包括5‑20wt％硅氧烷偶联剂改性玻璃纤维粉；所述硅氧烷偶联剂改性玻璃纤维粉的制备方法如下：将硅氧烷偶联剂溶解在水/乙醇混合溶液里，搅拌均匀；玻璃纤维研磨过1000目筛得玻璃纤维粉，加入溶液中，超声处理；超声之后，乙醇清洗、干燥，即得。相对于纯聚氨酯混凝土，添加15wt％玻璃纤维粉复合物制备的聚合物增强了38.7％的静态弹性模量，112.0％抗折强度，225.3％抗折模量和44.9％的粘接强度。
