Abstract
A kind of high-strength and low-cost combined manhole cover, comprise fiber reinforcement bottom, reinforcing bar packing layer and the hard abrasion-resistant top layer of height, by by weight tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4 being mixed and are made as the hard curing compound of pulverous self-control, different reinforcing material is used to be composited at well lid different parts.Fiber reinforcement is used, to ensure its supporting capacity in well lid bottom; Use steel mesh reinforcement to strengthen and mass filler, to improve product non-deformability in middle part; Use on top the material that hardness is higher, wear-resisting weather-proof is good, and design adopts different pattern and different colours.The well lid of such preparation can meet wear-resisting weather-proof requirement, has again beautiful feature attractive in appearance.
Description
Technical field
The present invention relates to a kind of high-strength and low-cost combined manhole cover of multilayer materials, belong to road building materials field.
Background technology
Well lid is the closure going out population top leading to underground installation, and the place of the communal facilities such as every installation tap water, telecommunications, electric power, combustion gas, heating power, fire-fighting, environmental sanitation all needs to install well lid.Along with the develop rapidly of China's economy, the construction of China's infrastructure welcomes again a new cycle, and the market demand of well lid in urban planning and road construction is huge.Before well lid material therefor, major part is steel concrete material.Due to steel concrete enbrittle greatly, the easy defect such as aging, easy fracture, and replace by the material such as cast iron, ductile iron.At present, cast iron (containing ductile iron) well lid consumption is more than 90%.But casting iron well lid has recovery value and often stolen, the event of car crash is caused to happen occasionally thus.In order to solve the stolen problem of well lid, casting iron well lid installs anti-theft device, but adopt anti-theft device to add cost, but can not tackle the problem at its root, and bring inconvenience to use.
Summary of the invention
The object of the invention is: a kind of high-strength and low-cost combined manhole cover is provided.
In order to achieve the above object, the scheme adopted is: a kind of high-strength and low-cost combined manhole cover, comprises fiber reinforcement bottom, reinforcing bar packing layer and the hard abrasion-resistant top layer of height; Described fiber reinforcement bottom consists of tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4, glass fiber 2 ~ 5 by weight; Described reinforcing bar packing layer consists of tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4, stone 8 ~ 15, reinforcing bar 0.9 by weight; The hard abrasion-resistant top layer of described height consists of tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4, quartz sand 3 ~ 6, resin 0.5 by weight.
The beneficial effect of employing such scheme is: combined manhole cover of this formula adopts hierarchical composite technique, uses different reinforcing material at well lid different parts.Fiber reinforcement is used, to ensure its supporting capacity in well lid bottom; Use steel mesh reinforcement to strengthen and mass filler, to improve product non-deformability in middle part; Use on top the material that hardness is higher, wear-resisting weather-proof is good, and design adopts different pattern and different colours.The well lid of such preparation can meet wear-resisting weather-proof requirement, has again beautiful feature attractive in appearance.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
A kind of high-strength and low-cost combined manhole cover, comprises fiber reinforcement bottom, reinforcing bar packing layer and the hard abrasion-resistant top layer of height; Described fiber reinforcement bottom consists of tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4, glass fiber 2 ~ 5 by weight; Described reinforcing bar packing layer consists of tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4, stone 8 ~ 15, reinforcing bar 0.9 by weight; The hard abrasion-resistant top layer of described height consists of tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4, quartz sand 3 ~ 6, resin 0.5 by weight.
The processing method of combined manhole cover of this formula is: by weight tertiary fourth fat 0.025, methyl ethyl ketone peroxide 0.015, zinc stearate 0.6, calcium hydroxide 0.02, styrene 0.8, polystyrene 0.4 to be mixed and to be made as the hard curing compound of pulverous self-control stand-by; By weight making hard curing compound 1.86 by oneself and reticular glass fiber 2 ~ 5 is positioned over well lid bed die, make upper and lower at reticular glass fiber of the powder uniform fold of the hard curing compound of self-control, matched moulds is heated to 120 DEG C, demoulding preformation bed die is stand-by after pressure 20T5 minute; By weight will make hard curing compound 1.86 by oneself, quartz sand 3 ~ 6, resin 0.5 be put in well lid backform and stir, and matched moulds is heated to 120 DEG C, demoulding preformation backform is stand-by after pressure 20T5 minute; By weight will make hard curing compound 1.86 by oneself, stone 5 ~ 15, net structure reinforcing bar 0.9 be put in backform in mould of the same size, the consumption of stone material is suitably adjusted according to the intensity of the kind and manufactured goods of inserting stone material, and making powder uniform filling gap and the top and bottom of the hard curing compound of self-control, matched moulds is heated to 120 DEG C, demoulding preformation middle level mould is stand-by after pressure 20T8 minute.
Need to use special backform and bed die according to client, by the end, in, top, layer prefabricated molds put into successively, matched moulds is heated to 140 DEG C, behind pressure 150T10 ~ 15 minute the demoulding make.
