Abstract
The present invention relates to a technological process for making high-strength composite manhole cover and grate. Said technological process includes the following steps: making surface layer, making resin and quartz powder according to a certain ratio, stirring them and placing them into mould, and placing glass-fibre cloth impregnated with resin on the surface layer; injecting filling material to form filling layer; layer-by-layer superimposing glass-fibre clothes impregnated with resin, striking off, forming base layer; and solidifying and forming the invented product. Its load-bearing capacity, acid-resistant, alkaline-resistant and ageing resistant properties can be up to national standard.
Description
Technical field
The present invention relates to the manufacturing process of a kind of high-strength compound well lid, grate and well lid thereof, grate, particularly relate to the various inspection shafts that are used on various underground pipelines in city and the highway and downspout strainer, the tree grate of road both sides.
Background technology
Traditional well lid is casting iron well lid, and its cost height gets rusty easily, fracture, and poor corrosion resistance, often stolen again, cause accident to take place, adopt the different composite material to replace the research application development of cast iron manufacturing well lid very fast for this reason in recent years, solved the problem that well lid is lost preferably, but combined manhole cover remains in some defectives, for example: compressive strength and rigidity are lower, supporting capacity is poor, and application life is short, and product quality can not reach existing national standard.The downspout strainer of road both sides exist equally stolen after, cause accident to take place.Road both sides trees grate also exists stolen, and tree root such as is compromised at phenomenon, therefore, is necessary to provide a kind of high-strength compound well lid, grate, meets the demands.
Summary of the invention
The purpose of this invention is to provide a kind of high-strength compound well lid, grate manufacturing process and well lid thereof, grate, this well lid, grate manufacture craft are easy, compact conformation, and the compressive strength good rigidity, the scope of application is wide.
For achieving the above object, the present invention takes following design scheme: the manufacturing process of a kind of high-strength compound well lid, grate, and it may further comprise the steps: the processing top layer, resin, quartz powder are measured stirring in proportion, go into mould, on the top layer, place the glass fabric that flooded resin; The filling inserts forms packed layer; The glass fabric that soaked resin that is layering is wipeed off, forms bottom; Curing molding.
A kind of high-strength compound well lid, it comprises: top layer, packed layer and bottom, described packed layer are the mixture layer of resin, quartz powder, granite fragment; Bottom is the glass fabric that flooded resin; The top layer is the mixed layer of resin and quartz powder, has at least one deck to flood the glass fabric of resin on the face of top layer.
Resin in the described packed layer: quartz powder: the consumption weight ratio of granite fragment is 0.15-0.2: 0.15-0.2: 1, and the consumption weight ratio of resin, quartz powder is 0.7-0.8 in the described top layer: 1.
The thickness of used glass fabric is generally 0.1mm, 0.2mm, and 0.4mm, its number ratio is 1: 2: 2 when making more than three layers.
Among the present invention, no matter the used resin of top layer or bottom can be a diglycol neighbour benzene resin, for example the trade mark is 196# or 191#.Glass from cloth can select alkali-free, middle alkali, sth. made by twisting is arranged, non-twist, cloth shape or synnema shape.
The number of plies of described glass fabric is: heavy well lid face has triplex glass cloth, end 18-35 layer on the top layer; The plain edition well lid has two layers of glass fabric on the top layer, thickness is 0.2mm, 0.4mm, and the end is the 8-14 layer; Light-duty well lid is 0.2mm on the top layer layer of glass cloth thickness being arranged then, end 3-5 layer.
The well lid raw material of the present invention special-used colour starch of can annotating to produce the inspection shaft lid of different colours, uses fire-fighting, municipal administration, combustion gas, telecommunications, electric power and subdistrict greening in every profession and trade on the ground on the inspection shaft of various uses, has obvious warning function.
Advantage of the present invention: recycle the composite material that is worth owing to adopted not have, stone is as main auxiliary material, and not only cost is low, and has fundamentally solved the problem that well lid, grate are stolen, and has avoided the generation of accident, its obvious social benefit.Adopt structure provided by the present invention, the supporting capacity of product and every index all meet or exceed national city-building industry standard CJ/T121-2000, acid-fast alkali-proof and ageing resistace be the value of being up to state standards all, this product can replace traditional well lid fully, satisfies the requirement of every profession and trade to various model well lids and downspout strainer, tree grate.

The specific embodiment
As shown in Figure 1 and Figure 2,1 is the top layer, is the top layer of being made by resin, quartz powder, and the weight ratio of its consumption is 0.7-0.8: 1, and be 0.2mm for layer of glass cloth thickness in its surface.2 is packed layer, and it is made by resin, quartz powder, granite fragment, and its weight ratio is 0.15-0.2: 0.15-0.2: 1,3 is bottom, and it is arranged by 5 layers of glass fabric and forms, and 5 layers of glass fabric are respectively 0.1mm one deck, 0.2mm two layers, two layers of 0.4mm are impregnated resin therebetween.Well lid of the present invention can be done squarely or other shapes, depends on the needs.
Processing method is as follows:
The first step: process the top layer: resin, quartz powder are measured in proportion put into agitator, after the adding curing compound stirs evenly, brush on the mould of first-class release agent, natural coagulation, the glass fabric that flooded resin is also placed on the moulding top layer on the top layer.
Second step: the filling inserts forms packed layer: resin, quartz powder, granite fragment are measured in proportion put into stirred vessel, annotate simultaneously after quantitative mill base and auxiliary agent etc. stir evenly, pour in the mould that forms the top layer, by vibratory compaction, intensive formation packed layer.
The 3rd step: finish bottom: will soak the glass fabric of resin, and press the difference of product type, and select the glass fabric and the different numbers of plies, and be layering on request, and in additive process, adopt special tool that glass fabric is wipeed off, and form bottom.
The 4th step: curing molding: the product stripping of spontaneous curing in the mould after 4 hours sent into the heating cure stove, and its furnace temperature is about 60-90 ℃, solidifies 6 hours final formation colored high-strength compound well lid grates of the present invention
The manufacturing process of downspout strainer, tree grate is identical with well lid among the present invention, structure is basic identical, just on the number of plies, the general employing on the top layer has one deck to soak the glass fabric of resin, bottom is two layers and soaked the glass fabric of resin or more than two layers, adopt 0.2mm, the glass fabric of 0.4mm in the time of two layers.
