A high-strength steel-plastic composite water grate and its manufacturing method

Abstract

The invention discloses a high-strength steel-plastic composite water gate and a manufacturing method thereof, and belongs to the field of urban road drainage fields. A gate body of the water gate is composed of a core body and a coating body, wherein the core body is prepared from long steel fibers, epoxy resin, distearoyl isopropoxy aluminate and diacetone acrylamide, and the coating body is prepared from waste mulching film particles, epoxy resin, epoxidized soybean oil, chopped steel fibers, chopped glass fibers, chopped carbon fibers, fly ash, calcium sulfate crystal whiskers, waste nickel sand, zinc oxide, distearoyl isopropoxy aluminate, diacetone acrylamide, butyl stearate and 2,6-di-tert-butyl-4-methylphenol. The water gate is manufactured by taking the a surface-treated steel fiber mesh as the core body and taking a resin-based material prepared by mixing the waste mulching film, the waste nickel sand and the like as the coating body through injection molding at a time. The finished product not only has the advantages of being low in weight, good in toughness, high in corrosion resistance and wear resistance and not prone to be aged, but also has the advantages of being attractive in appearance, high in resistance and long in service life.

Description

Technical field [0001] The invention belongs to the field of urban road drainage, and relates to a water grate for urban road drainage, in particular to a high-strength steel-plastic composite water grate and a manufacturing method thereof. Background technique [0002] In the urban drainage system, the gutter is the entrance for surface runoff rainwater to flow into the sewage system, and the rainwater grate is set at the gutter to filter debris. The existing rainwater grate usually consists of multiple grid bars or square holes to form a grid structure, which can filter and trap debris in the water while draining water. There are two main types of rainwater grate: vertical grate and flat grate. The installation of vertical gutters needs to maintain a certain depth of water. In some towns, roads are maintained year by year and the road surface is increased, which reduces the vertical grate section and affects water collection capacity. . Limited by conditions, the flat grate i...

AI Technical Summary

Problems solved by technology

Although the water grate made of cast iron has good rigidity, its disadvantages are also obvious. The material is brittle, has low tensile strength, weak impact resistance, is easy to break, and is easy to break, and because the material has recycling value, it is often stolen and lost. Seriously, vehicle damage and casualty accidents often occur in inspection wells where water grates are lost

The water grate made of cement is still very brittle, the toughness is not good, it is easy to break, the surface is not smooth, it is not very beautiful, and it is more likely to be damaged, which greatly shortens the service life and needs to be replaced frequently

[0004] With the continuous development of the resin industry, especially the increase in the variety of synthetic resins and the strengthening of their performance, water grates made of resin-based materials have appeared. The force attenuation is fast, and the safe use period is short under heavy traffic loads. Moreover, most of the water grates made of resin-based materials use steel bars or steel plates as the skeleton, which still has the risk of being stolen and needs to be replaced frequently
