Nonmetal composite material pit and canal cover and manufacturing method thereof
The invention discloses a non-metal composite material pit and canal cover and a manufacturing method thereof. The preparation method comprises the following steps: S1, proportioning the following rawmaterials in percentage by weight: 30%-55% of white quartz sand, 15%-25% of powdery filler, 3%-6% of a fiber material, 3%-4% of a curing agent, 0.03%-0.04% of an accelerant and the balance of resin;S2, mixing an accelerant with the resin; S3, adding the curing agent, the fiber material, the white quartz sand and the powdery filler into the resin, and stirring; S4, putting the mixture obtained inS3 and the pultrusion grid framework into a mold; and S5, starting a vibration table to enable the mixture in the mold to be vibrated and formed, and then standing. The pultrusion grid is used as theframework, the problems of corrosion and uneven expansion among different materials do not need to be worried about, the framework does not need to be completely covered with the panel, the overall weight is greatly reduced while the strength is guaranteed, the vertically-arranged water through holes are more attractive, and installation of the corners of the ditch is more convenient.
本发明公开了一种非金属复合材料坑渠盖及其制造方法，包括以下步骤：S1按重量百分比对以下原料进行配比：白英砂30%～55%、粉状填充物15%～25%、纤维材料3%～6%、固化剂3%～4%、促进剂0.03%～0.04%、余量为树脂；S2将促进剂与树脂混合S3；把固化剂、纤维材料、白英砂和粉状填充物加入树脂中搅拌S4；将S3得到的混合物以及拉挤格栅骨架放入模具；S5开启震动台使模具中的混合物震动成型，随后静置。通过使用拉挤格栅作为骨架，无需担心腐蚀、不同物料间膨胀不均匀问题，面板也无需完全包覆骨架，在保证强度的同时大大减轻整体重量，竖向设置的通水孔更美观、更方便水沟拐角处的安装。
