The invention discloses a square purlin preservative and a preparation method thereof, the purlin square cross section, one group of opposite sides is a double-layer structure, the square purlin by sections was two units are connected to the groove. During the preparation of glass fiber and unsaturated polyester mixed glue, and then into the mold curing unit structure, and then glue in the unit structure to be connected to the part, and finally bonded and solidified, obtain square anticorrosive purlin. The invention adopts the purlin sections was two units opposite groove connection, and a set of edges is a double-layer structure, forming a purlin compared to the traditional drawing, the short side part of the increase of the thickness of a part, can significantly enhance the tensile strength and bending strength, and easily fixed by screws. Moreover, the forming time is greatly shortened and the production capacity is greatly improved, which can reduce the repeated setting of the growth line, greatly save the production cost and improve the working efficiency.

技术介绍
FRP纤维增强复合塑料,全称是玻璃钢纤维增强塑料,又称玻璃钢材料,是以玻璃纤维及其制品(玻璃带、毡、沙等组合而成)作为增强塑料,以合成树脂做基本的一种复合材料,其强度相当于钢材又含有玻璃成分,也具有玻璃纤维的色泽、形体,耐腐蚀、电绝缘、隔热等性能。FRP材料,在防腐领域的成功应用已超过80年,如化工储罐,地下给排水管道,海上游船,风电设施等,其卓越的防腐蚀、耐老化性能得到了广泛认同。檩条在坡屋面中常搁置于屋架或斜梁上,起支撑作用,减小跨度和小型次梁。防腐檩条是以不饱和聚酯树脂,无碱玻璃纤维纱、加工助剂为主要原材料,按一定的比例混合,经过特别的模具挤压、拉拔而形成的高性能型材料。防腐檩条设计合理,产品具备钢材的强度,并且从根本上解决了金属钢材易腐蚀的弱点。使具有强度高,防腐性好,安装效率高和可靠性长久等有点,而成为大、中厂房工程安装材料。特别使用临海建筑、轧钢厂、冶炼厂、化肥厂、铝业氧化车间、海产养殖等高酸碱腐蚀环境中的工业建筑。现有 ...
