Abstract
The invention relates to a manhole cover and a production method thereof. The manhole cover is made from additives, synthetic resins, a curing agent and stone powder by the hot pressing process. The weight percentage ratio of the additives to the synthetic resins to the curing agent to the stone powder is 31%: 25%: 5%: 39% respectively. The additives are fabric cuttings or cotton yarn cuttings or a combination of the fabric cuttings and cotton yarn cuttings. The synthetic resins are the mixture of medium-density fibers, activated carbon fibers and melamine-modified urea-formaldehyde resin glues; and the medium-density fibers, the activated carbon fibers and the melamine-modified urea-formaldehyde resin glues are mixed at a weight ratio of 1: 1: 1 to form the synthetic resins.
Description
Technical field
The method that the present invention relates to a kind of manhole cover product and produce manhole cover is meant a kind of by the manhole cover and the production method thereof that add materials, synthetic resins, solidifying agent, the hot pressing of stone powder form especially.
Background technology
As everyone knows, all accelerating urbanization process all over the world now, in urbanization process, must need to carry out the construction in some roads and house, manhole cover is a kind of sincere city road for development traffic, the indispensable some in residential quarters, such as in the process of carrying out road and building construction, all needing to lay some pipelines or following aquaporin, on the extension path of these pipelines or following aquaporin, all need to be provided with some maintenance wells for maintenance and repair in the future are convenient, active well or following well, for preventing people or object simultaneously, the overall appearance effect that strengthens the city drops in the well, establish some well lids at the aboveground lid that all needs of this class, the material of traditional manufacturing well lid is generally all selected cast iron for use in everyday practice, present cast iron price comparison costliness, its price of the well lid of general 60 cm diameters is about 300-350 Renminbi.Casting iron well lid is except that cost is high, and its damaged stolen situation also happens occasionally, and has not just had overcover, this situation can cause the addiction that vehicle meets accident, the pedestrian meets accident to suffer from usually in well body top so in case the damaged or stolen situation of well lid takes place.Bring for municipal administration work and be stranded resistance, also can directly influence the road traffic running.
In order to solve the stolen situation of above-mentioned well lid, the water mud of answering that people are now many mixes loam reinforcing bar manufacturing well lid, value is not high can more effectively to solve the situation that well lid is stolen to this class well lid because it is stolen, this well lid price comparison is cheap, probably about 150 Renminbi, but because this well lid physical strength of restriction of material behavior is lower, the damaged situation of fracture takes place easily in concrete the use, work-ing life is shorter.
The well lid of two kinds of materials all exists shortcoming separately in concrete the use as mentioned above, bring great inconvenience to people concrete enforcement in the use, and this is the main drawback of conventional art.
Summary of the invention
The invention provides a kind of manhole cover and production method thereof, advantage in light weight, that the physical strength high price is cheap that the manhole cover that utilizes technical scheme of the present invention to produce has can be by people's widespread use, and this is to be main purpose of the present invention.
The technical solution adopted in the present invention is: a kind of manhole cover its by adding materials, synthetic resins, solidifying agent, the hot pressing of stone powder forms, this adds materials, this synthetic resins, weight percent between this solidifying agent and this stone powder is: 31%: 25%: 5%: 39%, this adds materials and is the mixture of broken or cotton husky head of cloth or the broken and cotton sand head of cloth, this synthetic resins is by medium density fiber, activated carbon fiber, cyanurotriamide modified urea resin glue mixes, this medium density fiber, this activated carbon fiber, this cyanurotriamide modified urea resin glue in the time of blended according to weight percent: mix to form this synthetic resins at 1: 1: 1.
In the time of the mixture of this broken and cotton husky head of adding materials for cloth this cloth broken with husky of this cotton between weight percent be: 50%: 50%.
Aforesaid this cloth broken and should cotton the spatial volume of husky head between 1 cubic centimetre to 5 cubic centimetres.
This solidifying agent is a thermal curing agents, and this stone powder is natural common stone powder.
A kind of production method of manhole cover comprises the steps:
The first step, will add materials to put in the chopping equipment and shred, between 1 cubic centimetre to 5 cubic centimetres, this adds materials is the broken mixture with cotton husky head of broken or cotton husky head of cloth or cloth through this spatial volume that adds materials after the chopping.
Second step, to add materials and synthetic resins through this that shreds in the first step as mentioned above, solidifying agent, the stone powder mixes in stirrer, obtain mixture, this adds materials, this synthetic resins, weight percent between this solidifying agent and this stone powder is: 31%: 25%: 5%: 39%, this synthetic resins is by medium density fiber, activated carbon fiber, cyanurotriamide modified urea resin glue mixes, this medium density fiber, this activated carbon fiber, this cyanurotriamide modified urea resin glue in the time of blended according to weight percent: mix to form this synthetic resins at 1: 1: 1, this solidifying agent is a thermal curing agents, and this stone powder is natural common stone powder.
The 3rd step, will be as mentioned above this mixture in second step drop in preformer, at room temperature carry out precompressed and obtain well lid cake embryo.
The 4th step, will be as mentioned above this well lid cake embryo in the 3rd step drop into and carry out hot-formingly in thermocompressor, the temperature of this well lid cake embryonic center of control was 180 ℃ of lasting hot pressing 5 minutes in hot-forming process, back depanning obtains the finished product manhole cover.
The 5th the step, to as mentioned above the 4th the step in this finished product manhole cover carry out deburring to finish the integral production step.
The production method of this manhole cover, in the time of the mixture of this broken and cotton husky head of adding materials for cloth this cloth broken with husky of this cotton between weight percent be: 50%: 50%.
Beneficial effect of the present invention is: manhole cover of the present invention by add materials, synthetic resins, solidifying agent, the hot pressing of stone powder forms, its performance is better than the cast iron manhole cover, and mechanical property reaches cast steel intensity, and also nobody steals under the unserviced in the open situation, has the incomparable premium properties of water mud manhole cover, produce market of the present invention is wide, the facility of drawing materials, practical value height, and its product weight is light, snappiness is not well broken, and water resistance is good, and dynamically holding capacity is 25 tons.
