Abstract
A high-strength and low-cost composite well lid comprises a fiber-reinforced bottom layer, a reinforcing steel bar padding layer and a high-hardness wearproof top layer. Pulverescent self-fabricated curing agents are formed by mixing the following materials, by weight ratio, 0.025 part of tertiary butyl ester, 0.015 part of methyl ethyl ketone peroxide, 0.6 part of zinc stearate, 0.02 part of calcium hydroxide, 0.8 part of styrene and 0.4 part of polystyrene, and different reinforcing materials are used in different parts of the well lid. The lower portion of the well lib is reinforced by using fibers to guarantee the bearing capacity of the well lid, net-shaped reinforcing steel bars and a large amount of padding are used in the middle portion of the well lid to improve the non-deformability of products, materials with high hardness and good wearproof and weather resistance performance are used on the upper portion of the well lid, and different patterns and different colors are designed and adopted. Thus, the manufactured well lid can meet the wearproof and weather resistance requirements, and has the advantages of being attractive and beautiful.
Description
Technical field
The present invention relates to a kind of high-strength and low-cost combined manhole cover of multilayer materials, belong to the road building materials field.
Background technology
Well lid is the closure that goes out the population top that leads to underground installation, and the place of the communal facilitieies 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 the well lid material therefor, major part is the steel concrete material.Because steel concrete enbrittles greatly, the easy defect such as aging, easy fracture, and replaced by materials such as cast iron, ductile iron.At present, cast iron (containing ductile iron) well lid consumption is more than 90%.Often stolen but casting iron well lid has recovery value, cause thus the event of car crash to happen occasionally.In order to solve the stolen problem of well lid, anti-theft device is installed on casting iron well lid, but is adopted anti-theft device to increase cost, but can not tackle the problem at its root, and bring inconvenience to use.
Summary of the invention
The objective 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 high hard wear-resisting top layer; 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 wear-resisting 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.
Adopt the beneficial effect of such scheme to be: the combined manhole cover of this formula adopts hierarchical composite technique, at the well lid different parts, uses different reinforcing materials.Use fiber reinforcement in the well lid bottom, to guarantee its supporting capacity; In middle part, use steel mesh reinforcement to strengthen and mass filler, to improve the product non-deformability; Use the material that hardness is higher, wear-resisting weather-proof is good on top, and design adopts different pattern and different colours.The well lid of preparation can meet the wear-resisting weather-proof requirement like this, has again beautiful characteristics attractive in appearance.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
A kind of high-strength and low-cost combined manhole cover, comprise fiber reinforcement bottom, reinforcing bar packing layer and high hard wear-resisting top layer; 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 wear-resisting 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 the 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 being mixed and to be made as the hard curing compound of pulverous self-control stand-by; By weight make hard curing compound 1.86 and netted glass fiber 2 ~ 5 is positioned over the well lid bed die, the powder uniform fold that makes to make by oneself hard curing compound netted glass fiber up and down, after matched moulds is heated to 120 ℃, pressure 20T5 minute, demoulding preformation bed die is stand-by; Be put in the well lid backform and stir by weight making hard curing compound 1.86, quartz sand 3 ~ 6, resin 0.5 by oneself, after matched moulds is heated to 120 ℃, pressure 20T5 minute, demoulding preformation backform is stand-by; By weight will make hard curing compound 1.86, stone 5 ~ 15 by oneself, net structure reinforcing bar 0.9 is put in backform mould of the same size in, suitably adjust the consumption of stone material according to the intensity of the kind of inserting stone material and manufactured goods, and the powder uniform filling gap and the top and bottom that make to make by oneself hard curing compound, after matched moulds is heated to 120 ℃, pressure 20T8 minute, demoulding preformation middle level mould is stand-by.
Need to use special-purpose backform and bed die according to the client, by the end, in, top, a layer prefabricated molds put into successively, after matched moulds is heated to 140 ℃, pressure 150T10 ~ 15 minute, the demoulding is made.
