However, the existing well cover grate is formed by pressing steel plates in the using process, and the steel plates are easily corroded by the influence of an external environment in the using process, so that the well cover grate is deformed and damaged, the weather resistance of the well cover grate is poor, and meanwhile, the well cover grate is single in raw materials in the production process, serious in waste and inconvenient in recycling of resources.
Disclosure of Invention
The invention aims to solve the problems and provide a method for producing a manhole cover grate by using glass waste and phenolic resin.
The invention realizes the purpose through the following technical scheme:
a method for producing a manhole cover grate by using glass waste and phenolic resin comprises the following steps:
step 1: firstly, crushing glass products such as waste glass cups, glass plates and the like on a roller crusher, then melting the crushed glass in a melting furnace, and drawing the molten glass into glass filaments for later use;
step 2: mixing and stirring the liquid phenolic resin and the glass fiber prepared in the step 1 in a mixing roll;
and step 3: adding corresponding ingredients into the mixing roll in the step 2, and continuously stirring until the mixed materials are pasty;
and 4, step 4: adding the stirred paste material obtained in the step 3 into a pre-preheated hot-pressing mold, and controlling the hot-pressing temperature and time of the hot-pressing mold;
and 5: and (4) after the hot pressing in the step (4) is finished, firstly, cooling the hot pressing die by using a refrigerator, and then taking out the pressed well cover grate.
Furthermore, the ingredients in the step 3 comprise an ultraviolet absorber, a heat stabilizer, nano titanium dioxide, nano silicon dioxide and carbon powder, so that the well cover grate has good weather resistance, and the well cover is prevented from being damaged and deformed due to the influence of the external environment in the using process.
Furthermore, the hot pressing die in the step 4 is pressed by a 500-ton hydraulic press, the volume of the hot pressing die in the step 4 is 1.2 cubic meters, and the compact type of the well cover grate after hot pressing can be ensured by strictly controlling the forming space and the forming pressure of the well cover grate, so that holes are prevented from being formed in the well cover grate, and the forming quality of the well cover grate is ensured.
Further, the preheating temperature of the hot-pressing mold in the step 4 is 130-.
Further, the hot-pressing temperature of the hot-pressing mold in the step 4 is 155-165 ℃, and the hot-pressing time is 25-40min, so that the molding quality of the pressed well cover grate can be ensured.
The invention has the beneficial effects that:
the invention utilizes the waste glass waste products to be crushed, melted and drawn, then mixed and pressed with the phenolic resin, the ultraviolet absorbent, the heat stabilizer and other ingredients, and strictly controls the space, the temperature and the time of pressing and forming, thereby not only realizing the recycling of the waste glass waste products and saving the resources, but also effectively increasing the weather resistance of the produced well cover grate, leading the well cover grate not to be easily damaged and deformed by the influence of the external environment in the subsequent use process, and improving the production quality of the well cover grate.
