Abstract
The present invention relates to a manhole cover made of composite material. Said manhole cover is made up by utilizing reinforcement skeleton and composite material formed from (by wt%) 10-20% of unsaturated polyester resin, 2-10% of polystyrene, 2-8% of polyethylene, 0.5-2% of polyamide, 0.5-2% of polycarbonate, 0.1-0.5% of t-butyl perbenzoate and 10-25% of glass fibre and filler through the processes of die-pressing and forming.
Description
One, technical field
The present invention relates to the manhole well lid that uses in a kind of municipal engineering construction, exactly is a kind of composite drain cover.
Two, background technology
In the urban municipal construction, relate to a lot of ground pipe-networks engineering, as give, draining, heat supply, power supply, air feed, telecommunications, communication etc.All be reserved with manhole and supporting manhole cover (abbreviation well lid) on road, sidewalk, highway or square, parking lot, greenery patches, lawn etc., to guarantee the safety of pedestrian and traffic towards underground installation.Traditional well lid mostly is cast iron or concrete is prefabricated, and this well lid is thick and heavy, clumsy, transportation and open all inconveniently, and flap cooperates not driving fit, has when vehicle crosses and beats, and noise is big, and ironcasting easily stolen, and stays potential safety hazard.Along with the develop rapidly of organic composite material, nation-building portion issued " regenerating resin composite drain cover " industry standard (CJ/T121-2000) in 2000.This standard has been unified the standard with organic composite material processing and manufacturing well lid.
Three, summary of the invention
Problem to be solved by this invention is to select suitable organic material and compound proportion thereof, processes the well lid that meets the CJ/T121-2000 standard.
This well lid comprises reinforcing bar and composite material, and described composite material has following component and percentage by weight thereof:
Unsaturated polyester resin 10～20%
Polystyrene 2～10%
Polyethylene 2～8%
Polyamide 0.5～2%
Merlon 0.5～2%
T-butyl perbenzoate 0.1～0.5%
Glass fiber 10～25%
The filler surplus.
The preferred following percentage by weight of composite material each component:
Unsaturated polyester resin 14～18%
Polystyrene 4～8%
Polyethylene 4～6%
Polyamide 0.8～1.2%
Merlon 0.8～1.2%
T-butyl perbenzoate 0.2～0.4%
Glass fiber 14～22%
The filler surplus.
Described filler can be calcium carbonate, attapulgite, swell soil etc.
In composite material, can also add 0.1～0.5% pigment, give well lid certain color.
This well lid adopts compression molding.Mix after the composite material each component prepared burden in proportion, irritate mould then, in mould, give and leave cage of reinforcement, moulding at a certain temperature at last, cooling and demolding promptly gets well lid.
This well lid detects through economizing quality testing department, and the result is as follows:
| Project | The result | Standard |
| Compressive strength MPa | ????40 | ????≥30 |
| Rupture strength MPa | ????23 | ????≥14 |
| Toughness kj/m 2 | ????98 | ????≥95 |
| Resistance to freezing and thawing compressive strength loss late % | ????9 | ????≤13 |
| Heat ageing compressive strength relative change rate % | ????0.3 | ????≤0.4 |
| Artificial ageing rupture strength relative change rate % | ????2 | ????≤3 |
Inorganic bronsted lowry acids and bases bronsted lowry with 2% carries out corrosion resistance test, do not expand, indeformable, do not have be full of cracks, a surperficial nondiscolouring.
Well lid outward appearance pressure surface is smooth, and flawless does not have the Local Convex concave defect influence functional performance, and is airtight by touching with the bearing support face, when vehicle crosses balance do not have beat, noiselessness.In light weight, service life is long, can not lose, and can replace traditional casting iron well lid or concrete well cover fully.
Four, the specific embodiment
(1), now be example to prepare 100 weight fraction composite materials, non-limiting examples is described below:
1, get 20 parts of unsaturated polyester resins (UP), 10 parts of polystyrene resins (PS), 8 parts of polyvinyl resins (PE) are got 2 parts of 2 parts of Merlon of polyamide (PA) (PC), 0.5 part of t-butyl perbenzoate (TBP), 25 parts of glass fiber, calcium carbonate (CaCO
3) 32.5 parts, mix.
2, get 10 parts of UP, 2 parts of PS, 2 parts of PE, 0.5 part of PA, 0.5 part of PC, 0.1 part of TBP, 10 parts of glass fiber, 74.9 parts of attapulgites mix.
3, get 18 parts of UP, 8 parts of PS, 6 parts of PE, 1.2 parts of PA, 1.2 parts of PC, 0.4 part of TBP, 22 parts of glass fiber, 43.2 parts of swell soils mix.
4, get 14 parts of UP, 4 parts of PS, 4 parts of PE, 0.8 part of PA, 0.8 part of PC, 0.2 part of TBP, 14 parts of glass fiber, CaCO
362.2 part, mix.
5, get UP16 part, 6 parts of PS, 5 parts of PE, 1 part of PA, 1 part of PC, 0.3 part of TBP, 18 parts of glass fiber, CaCO
352.7 part, mix.
(2) processing of well lid
Pour in the molding press after above-mentioned composite material fully mixed, be reserved with cage of reinforcement in the molding press, consumption is about about 10% of composite material, and compacting is 10～30 minutes in the time of 140～180 ℃, and cooling and demolding promptly gets well lid after the moulding.
Claims (3)
1, a kind of composite drain cover comprises reinforcing bar and composite material, it is characterized in that: described composite material has following component and percentage by weight thereof:
Unsaturated polyester resin 10～20%
Polystyrene 2～10%
