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 nylon embedded hair, MC nylon shavings, waste nylon toothbrushes, waste umbrellas and waste Nike shoes from waste tires, cut them into pieces, rinse and dry them, prepare appropriate amount of melon seeds, flake stones or medium-coarse sand and rinse them with water dry. Take 100kg of nylon embedded hair, 10kg of MC nylon shavings, 20kg of glass fiber, and 300kg of melon seeds and flakes in waste tires, and carry out mechanical mixing under normal temperature and normal state; the above-mentioned mixture is placed in a special synthesis machine, and in the synthesis machine The above mixture is heated to 250--260°C and fully stirred until it becomes soft plasticine; put the aforementioned soft plasticine-like mixture in a mold with a transfer steel skeleton, and use a 315-ton four-column hydraulic press to place it against the above mold...

Abstract

The invention relates to a novel road manhole cover, and especially relates to nylon alloy components and preparation technology; nylon physics synthesis alloy of various performances and inorganic material are mixed under specific temperature and pressure conditions so as to form the road manhole cover; the novel manhole cover belongs to building material field road manhole cover new material, and comprises nylon6, MC nylon, glass fiber, sands or rocks with the following weight ratio: 1: 0.1:0.2: 2.6-3; the technical method comprises the following steps: primarily mixing the materials according to the weight ratio of 1: 0.1:0.2: 2.6-3; placing the primarily mixed material in a specific synthesis machine under 250-260 DEG C temperature environment; placing soft plasticine material into a die with a steel rib moving support, pressurizing to 120-200 tons, maintaining the pressure for 5-10 minutes and removing the die, placing the product into a tempering pond, and boiling the product so as to remove internal stress. The novel road manhole cover is not recyclable, thus realizing antitheft purpose.

Description

technical field [0001] The invention relates to a new type of road manhole cover, especially the composition and production process of nylon alloy, which uses various nylons with different properties to physically synthesize nylon alloy and inorganic materials, and blends the 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 manhol...
