Abstract
The invention discloses a tough steel frame-free compound resin well cover and a production process thereof. The well cover comprises an upper cover and an outer ring. The upper cover and the outer ring respectively comprise compound resin and platinum cloth interlayers distributed at intervals in the compound resin. The well cover is made from the prepared raw materials by weight percent: 5-30% of resin, 50-70% of calcium powder, 1-3% of polystyrene, 10-25% of quartz sand and 2-3% of chopping yarn, and an amount of accelerating agent and an amount of curing agent are added according to air temperature; the layer number of the platinum cloth is 1-20. The production process of the well cover comprises the following steps of raw material mixing, mixed material and interlayer paving, extrusion forming, demoulding and the like. The well cover has good toughness, long service life and low production cost; compared with the original production cost, the production cost is reduced by 10%; moreover, one-time investment is little, and a special pressing machine and a purpose-made steel mold which have high cost do not need any more, but the production can be carried out only by a self-madesimple pressing machine and a self-made mold. In addition, the well cover does not contain metal materials, can not be rusted or stolen; the appearance design of the well cover can change monochromatic characters into multicolor image-text marking patterns.
Description
Technical field
The present invention relates to a kind of compound resin well cover and production technology thereof, particularly a kind of tough steel frame-free compound resin well cover and production technology thereof belong to road pipe network ancillary facility.
Background technology
Continuous development along with national economy and society, domestic city infrastructure progress rapidly, the road pipeline network construction constantly enlarges, the well lid demand that pipe network disposed significantly increases, the tradition well lid is casting iron well lid or cement well lid, because casting iron well lid is easily stolen, and heavy and corrosion easily, progressively withdrawing from the market in the nineties in last century is replaced by compound resin well cover.Existing compound resin well cover normally adopts the compound resin internal layer to add steel frame and makes, though this goods rigidity is pure, and poor toughness, very easily broken and damage; The steel frame that internal layer plays booster action is corroded easily, waits to erode to and to a certain degree can cause intermediate gaps to rot and damage; It is many to produce the disposable input of compound resin well cover, needs expensive special pressure machine and special steel mould, the cost of production height; For the compound resin well cover of enhancement mode, because its steel frame is greatly also stolen easily, losing of well lid tends to cause serious personal injury and economic loss.
In order to overcome the problem of above existence, people seeking always a kind of new substitute existing compound resin well cover technical scheme.
Summary of the invention
The present invention is in order to solve the existing technical problem of above-mentioned existing compound resin well cover, succeed in developing a kind of tough steel frame-free compound resin well cover and production technology thereof targetedly, can improve the toughness of compound resin class well lid, increase the service life, and reduce production costs.
The technical solution used in the present invention is as follows:
This tough steel frame-free compound resin well cover comprises loam cake and outer ring, and loam cake places on the step of outer ring endoporus seam, and the upper surface of the two maintains an equal level.Described loam cake comprises compound resin and platinum cloth interlayer inner spaced apart with it thereof, and the outer ring also comprises compound resin and platinum cloth interlayer inner spaced apart with it thereof.
Described loam cake and outside, outer ring all cover the compound resin surface course.The compound resin surface course that described loam cake top covers is manufactured with one or more color picture and text sign picture case.
The preparation raw material of described compound resin and proportioning by weight thereof are: resin 5-30%, and calcium powder 50-70%, polystyrene 1-3%, quartz sand 10-25%, short yarn cutting 2-3%, surplus is accelerator and curing compound; Described platinum cloth interlayer is the 1-20 layer.
The accelerator of described surplus and curing compound system according to temperature condition in the configuration raw material an amount of equal portions or not equal portions add and get final product.Accelerator is generally adopted 6% solution of cobalt soap liquid in styrene; Curing compound generally adopts 50% the paste of cyclohexanone peroxide in dibutyl ester.
Loam cake and outer ring that this tough steel frame-free compound resin well cover is included make respectively, and production technology is identical, and its processing step is as follows:
(1) raw material mixes
With the polystyrene in described compound resin raw material elder generation heat fused, again with all the other raw materials mixing and stirring in the container of packing into together;
(2) tiling mixed material and interlayer
The mixed material that the layer overlay last process is mixed in mould is added one deck by the good platinum cloth of the big cabinet of product area, spreads a layered material then and adds one deck platinum cloth, is paved with one deck mixed material at last until mould, buckles well mould, adds screw and fixes;
(3) extrusion modling
Put under the forcing press, the normal temperature extruding got final product in two minutes;
(4) demoulding
At temperature 10-40 Celsius ℃, leave standstill the demoulding after 30-120 minute.
The required well lid of road pipe network comprises that the supporting one in loam cake and outer ring is embedded in the pipe network well head and keeps in one plane with ground.Generally, because the loam cake load-bearing is stressed greater than the outer ring, the composition of raw materials of loam cake and platinum cloth interlayer are had relatively high expectations, and identical or different prescription and interlayer can be adopted in loam cake and outer ring, but require the weight capacity of the weight capacity of loam cake greater than the outer ring.
Tough steel frame-free compound resin well cover and production technology beneficial effect thereof: tough steel frame-free compound resin well cover good toughness, long service life, cost of production is low, reduce by 10% than original cost of production, and disposable less investment, need not adopt expensive special pressure machine (separate unit need 200,000 yuan) and special steel mould (single cover needs 50,000 yuan), only need self-control simple press (only needing 0.5 ten thousand yuan) and can produce from molding jig (only need 0.06 ten thousand yuan); In addition, this well lid is the containing metal material not, and not corrosion can be not stolen; The well lid appearance design can change monochromatic character and indicate pattern for the multicolour picture and text.
