Description
Technical field
The present invention relates to inspection well cover manufacturing technology fields more particularly to a kind of utilization waste mulching film and waste nickel sand to prepare again
Close the preparation method of well lid.
Background technique
Manhole cover is commonly called as inspection well cover, plays a crucial role in urban construction.With science and technology it is continuous
How progress, design that bearing capacity is strong, long service life, structurally reasonable manhole cover are to be engaged in the design of manhole cover structure
The matter of utmost importance considered required for personnel.Currently, common manhole cover mainly has armored concrete manhole cover and cast iron inspection
Look into well lid.Castiron well cover because recovery value height due to be often stolen, though armored concrete manhole cover recycle value compared with
It is low, but its brittleness is big, it is weaker to support ageing resistance, easily produces fracture.Someone utilizes flyash or glass in the prior art
Steel does well lid, compensates for the defect of casting iron well lid and concrete manhole cover, but existing market usage amount is little, cannot obtain very well
Popularization.
Plastic mulching cultivation technology rose since the 1970s, rapidly American-European, Japan and other countries are universal, 80 years
The farmland area of friend's film-mulching technique is answered constantly to expand for later most developing countries.But with mulch application
Increase, negative effect also gradually displays, and since residual film is not easily recycled difficult to degrade, causes sternly to farmland and ecological environment
The influence of weight, renames as " white pollution " by original " White Revolution " by people.The present invention plans waste mulching film as main
Raw material prepares Resin man-hole cover, however, the existing well lid made of waste mulching film powder, intensity difference, to reinforce well lid product
Intensity, the solution of technical aspect is typically all to thicken well lid product, but well lid product can also be made to become very heavy,
It thus needs to add appropriate waste and old casting nickel sand in Resin man-hole cover preparation, prepares compound resin well cover meet demand.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provides and a kind of utilizes waste mulching film and waste nickel sand system
The preparation method of standby combined manhole cover.
The present invention is achieved by the following technical solutions:
A kind of preparation method preparing combined manhole cover using waste mulching film and waste nickel sand, comprising the following specific steps
(1) dry after cleaning out the waste mulching film of recycling, it is then fed into useless film pelletizer and carries out crushing granulation, obtain
Granular mulch is stand-by；Be added useless nickel sand according to certain mass ratio, at the same according to certain formula be added a certain amount of discarded machine oil,
The auxiliary agents such as antiaging agent stir to obtain mixed material by blender；
(2) mixed material that step (1) obtains is put into hot environment and is plasticized, so that regenerated plastics are changed by solid pellet
Then viscous state is extruded into material by extruding machine, will be put at material in well lid mold, and be pressed and molded under certain pressure conditions
10-15 minutes；
(3) well lid after molding is demoulded, naturally cools to certain temperature after demoulding, while hot rough grinding, after rough grinding
Room temperature is naturally cooled to, smart polishing is carried out, is put in storage after examining qualified compound national standard.
A kind of preparation method preparing combined manhole cover using waste mulching film and waste nickel sand, according to one described in step (1)
Useless nickel sand is added in fixed mass ratio, refers to the 50-51% that the amount of useless nickel sand for graininess film quality is added.
A kind of preparation method preparing combined manhole cover using waste mulching film and waste nickel sand is certain described in step (1)
Formula, specifically: graininess mulch 100-105, useless nickel sand 50-51, discarded machine oil 10-12, anti-aging agent 1-2, silane coupling agent
1.5-2。
A kind of preparation method preparing combined manhole cover using waste mulching film and waste nickel sand, high temperature ring described in step (2)
Border refers to the temperature at 150-200 DEG C.
A kind of preparation method preparing combined manhole cover using waste mulching film and waste nickel sand, certain described in step (2)
Pressure conditions under, refer under the pressure of 300MPa.
A kind of preparation method being prepared combined manhole cover using waste mulching film and waste nickel sand, step are being demoulded described in (3)
After naturally cool to certain temperature, refer to and be cooled to 90-110 DEG C.
The invention has the advantages that the present invention is using waste mulching film and useless nickel sand as main material, scientific and reasonable control
The temperature of processing fills generation mechanical mixture with the filler nickel sand that gives up, gives up so that waste mulching film melts under the conditions of certain temperature
A certain amount of metallic nickel and silica are still remained in nickel sand ingredient, these are all extraordinary reinforcing materials, reasonably
Addition improves the intensity, wearability and rigid hardness of Resin man-hole cover, in road inspection well facility, vehicle to be passing to be drawn
Well lid deformation is played, no replacement is required for long-time service；By the addition of suitable anti-aging agent, solve that waste mulching film is weathered to ask
Topic, and aging can be continued with the time in use, stable effect is played to the free radical of generation；The present invention is made
95% or more compound resin well cover raw material use waste, meet environmental protection and the requirement of resource reutilization, produce simultaneously
Product have the characteristics that mechanical properties strength is high, alkaline-resisting, heat-resisting, cold-resistant, elasticity modulus is high, and preparation process is simply convenient for industry
Control, is worthy to be popularized.
