Abstract
The invention relates to a composite resin well lid. The composite resin well lid consists of the following material components in parts by weight: 30-50 parts of waste PE (polyethylene) materials, 20-40 parts of high-pressure films and 20-40 parts of coal ash. According to the composite resin well lid disclosed by the invention, the waste PE materials, the high-pressure films and the coal ashes are taken as materials to synthesize a resin well lid, so that materials are easily available and are all leftover materials obtained by other productions; the composite resin well lid is lower in cost, satisfies a material reproduction principle, and is prepared into a high-temperature resistant, pressure-resistant and anti-impact vertical well lid by virtue of an effective synthesis method.
Description
Technical field
The present invention relates to matrix material technology of preparing, especially a kind of compound resin well cover.
Background technology
In recent years, along with the develop rapidly of Process of Urbanization Construction, more cable, optical cable ditch well increase gradually, and the consequent is exactly that the demand of well lid increases gradually.Casting iron well lid is because its fragility is more obvious, and easily stolen, and the thicker very difficult unlatching of cement well lid, has caused certain difficulty and fragility also obvious to the maintenance of ditch well.Along with the exploitation newly just coming, vertically well lid goes on the market gradually, but in order to ensure endurance and the intensity of well lid, too much adding of the composition such as auxiliary agent and property-modifying additive on stream, its preparation process has produced too much toxicity, pollutant component, easily cause to produce and pollute, operator is also easily caused to personal injury.
Summary of the invention
The present invention is directed to the deficiencies in the prior art part, a kind of recycle that realizes resource is provided, reduce the compound resin well cover polluting.
For achieving the above object, technical scheme of the present invention is:
A kind of compound resin well cover, its feed composition and parts by weight thereof are respectively:
30～50 parts, waste and old PE material
20～40 parts of high pressure mulch films
20～40 parts, flyash.
And the preparation method of above-mentioned compound resin well cover is:
Waste and old PE material, high pressure mulch film, flyash are put into milling machine and carry out mixingly, thing to be mixed becomes after even melts, stops heating;
Uniform mixture is put into pressing machine to be suppressed.
And described milling machine Temperature Setting is 180 DEG C.
And described well lid comprises the walling crib of well lid lid and its outer rim, wherein the press time of well lid lid is 45min, and the press time of walling crib is 25min.
Advantage of the present invention is:
The present invention has adopted waste and old PE material, high pressure mulch film, flyash as raw material, carry out manhole cover of synthetic resin, not only raw material is easy to get and is the scrap stock after other productions, its cost is lower, meet the principle that material regeneration is produced, then by effective synthetic method, be prepared into high temperature resistant, withstand voltage, shock proof vertical well lid, be on feed composition or in the course of processing all without the adding of the interpolation auxiliary agents such as other modifications, chain extension, production process environmental protection.The Resin man-hole cover supporting capacity providing in the present invention can reach 550KN, and its attenuation degree is decay 15% in 50 years.
