Embodiment Construction

[0007] Take waste and old nylon and glass fiber and melon seed chips or sand as an example to make road manhole covers as raw materials. Take 100kg of nylon embedded hair, 10kg of MC nylon shavings, 20kg of glass fiber, 260-300kg of sand or stones in waste tires, and carry out mechanical mixing at normal temperature; put the above mixture in a special synthesis machine, and in the synthesis machine In the process, heat the above mixture to 250-260°C and then fully stir it until it becomes soft plasticine; put the aforementioned soft plasticine mixture into a mold equipped with a steel frame, and use a 315-ton four-column hydraulic press to place the The plasticine-like mixture in the above-mentioned mold is pressurized for 5-10 minutes, placed in boiling water and cooked for 15 minutes per mm thickness to eliminate internal stress and make nylon road manhole cover or water grate manhole cover.

[0008] In the present invention, various nylons of different types are scientifica...

Abstract

The present invention relates to a nylon alloy component for anti-theft road manhole cover and a manufacturing technology. The nylon alloy component includes nylon 6, MC nylon, glass fiber, sand or gravel, and the weight ratio of the components is 1:0.1:0.2:2.6-3. The manufacturing technology includes: preliminarily stirring the above substances with a weight ratio of 1:0.1:0.2:2.6-3, placing the preliminary stirred material at the temperature of 250-260 DEG C in a dedicated synthesis machine to fully mix into a state of soft plasticine, then placing the soft plasticine material in a mold provided with a steel rib shift force frame, pressurizing to 120-200 tons, keeping the pressure for 5-10 minutes to demold, putting the product into a tempering pool after demolding to cook by boiling water in order to eliminate the internal stress. The manhole cover obtained by the invention can not be recycled, thereby achieving the purpose of anti-theft.

Description

technical field [0001] The invention relates to a nylon alloy component and a manufacturing process. The nylon alloy is physically synthesized by various nylons with different properties and inorganic materials are blended to make a road manhole cover under specific temperature and pressure conditions. Achieve the effect of replacing iron with plastic, which is non-recyclable and prevents theft. It belongs to the new material of road manhole cover in the field of building materials. Background technique [0002] Along with the continuous construction and development of urban roads, the inspection manhole covers and drainage manhole covers of various underground facilities under the roads are increasing rapidly. Traditional road manhole covers include cast iron manhole covers, concrete manhole covers, plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are easy to steal, concrete manhole covers are easy to peel off and break, pla...
