Abstract
The invention relates to a building engineering material, in particular to a regenerated composite material, which is convenient in matching ratio, simple in operation and low in cost, meets various performance indexes and is applicable to manufacturing well rings and well covers. The regenerated composite material comprises the following components in percent by weight: 60-65% of waste polyethylene, 30-35% of waste nickel sand, 1-3% of anti-ageing agent, 1-3% of rosin and 1-2% of waste engine oil, wherein the coumarone with the same percent can be used for replacing the rosin. Compared with the prior art, the regenerated composite material has the beneficial effects that the waste polyethylene and the waste nickel sand are adopted as main raw materials of the material; under the premise of ensuring the performance indexes, the used amount of the waste nickel sand is reduced, and simultaneously a simpler and effective aid is adopted, so that the resource is saved, the cost is reduced, the environment is protected and large economic benfit and environmental benefit are created; and the compression strength is good, the bearing capability is high, the matching is convenient, the operation is simple, and the use is convenient, so that the regenerated composite material is very beneficial to production and application.
Description
Technical field
The present invention relates to a kind of architecture engineering material, be specially a kind of regenerated composite material that is applicable to make walling crib, well lid.
Background technology
On the street in city, the inspection chamber of the various uses that is seen everywhere, inspection chamber, fire-fighting inspection chamber, combustion gas inspection chamber, power check well, communication inspection chamber etc. for example supply water, what mostly all adopts is well lid and the walling crib that traditional cast iron is made inspection chamber, although the supporting capacity of casting iron well lid is strong, its material cost is with to expend the energy large, perishable its various aspects of performance index that affects, need to make regular check on, and because it has higher recovery value, so often stolen; Be corrosion or stolenly all may cause various accidents that the little normal operation that then affects various systems greatly then may cause casualties and financial loss.
The problem that exists in order to solve above-mentioned technology medium cast iron well lid and walling crib, well lid and walling crib that matrix material just occurred, what existing combined manhole cover all adopted is that the waste or used plastics that reclaims is done matrix, do toughener with abandoned mine slag or flyash, then add various auxiliary agents, compound through stirring again, extrude the compression moulding of pressurizeing at last after the fusing of heating.Wherein to be mainly polyethylene, polypropylene and polyvinyl chloride be main to waste or used plastics, and polyethylene comprises again Low Density Polyethylene and high-pressure polyethylene, and the hardness of high density polyethylene(HDPE) is relatively better; But still can not meet the demands, and various waste or used plastics mix, also further reduced material hardness, do toughener so add abandoned mine slag or flyash, the general toughener that adds is more, the intensity of making at last material is larger, the consequent is that fragility also can be larger, therefore waste or used plastics and all be controlled at about 1: 1 as abandoned mine slag or the ratio of flyash of toughener in the prior art, and need the miscellaneous auxiliary agent of adding to adjust properties of materials, just can make its various performance index that satisfy well lid and walling crib, troublesome poeration, proportioning is loaded down with trivial details, is unfavorable for improving producing and the simplification processing sequence.
Summary of the invention
The object of the present invention is to provide a kind of proportioning convenient, simple to operate, with low cost and satisfy the regenerated composite material that is applicable to make walling crib, well lid of property indices.
A kind of regenerated composite material that is applicable to make walling crib, well lid is characterized in that, each component and the weight percent of described material are: waste polyethylene 61%-65%, useless nickel sand 31%-35%, anti-aging agent 1%-3%, rosin 1%-3%, used oil 1%-2%.
Further, describedly a kind ofly be applicable to make in the regenerated composite material of walling crib, well lid, each component and weight percent are: waste polyethylene 62%, useless nickel sand 33%, anti-aging agent 2%, rosin 2%, used oil 1%.
Further, describedly a kind ofly be applicable to make in the regenerated composite material of walling crib, well lid, the coumarone of available same composition replaces described rosin.
The present invention has the following advantages compared to existing technology:
1) main two kinds of component waste polyethylenes and useless nickel sand in the described material, and the used oil in other three kinds of components of adding is the waste and scrap of recovery, economize on resources, solved the problem that well lid is lost, especially saved a large amount of metallic substance, also reduce simultaneously cost, reduce and sell and maintenance cost, greatly saved municipal funds.
2) owing to the main raw material that has adopted waste polyethylene and useless nickel sand as material, solved the problem of waste and old mulch film, handbag and the difficult contaminate environment of daily plastic articles, solved again the problem of useless nickel sand wash land occupation contaminate environment, turn waste into wealth, created huge economic benefit and environmental benefit.
3) simple adopt the matrix of waste polyethylene as material, waste polyethylene can form preferably high density polyethylene(HDPE) of toughness in the operation of following process, thereby the ultimate compression strength of the well lid of making and walling crib is good, supporting capacity significantly improves, combine together with useless nickel sand and auxiliary agent simultaneously, physical strength further promotes.
4) in the material component; the ratio of waste polyethylene and useless nickel sand is about 2: 1; increase by 37% than plastic waste consumption of the prior art; and the consumption of abandoned mine sand and flyash has reduced 27%; under the prerequisite that guarantees that material property is constant or even improve; the cost of abandoned mine slag and the flyash still cost than waste or used plastics is high; add that the waste or used plastics environmental disruption that is referred to as white pollution will be far longer than abandoned mine slag and the flyash that is called as grey rubbish; therefore the content increase of waste polyethylene in the material; the content decrease of useless nickel sand can make material lighten; cost; and can more be conducive to the protection of environment, the further expansion of the economic benefit that can get and social benefit.
5) auxiliary agent in the middle of the material component only adopts three kinds of anti-aging agent, used oil and rosin or coumarones, the various performance index of material have been guaranteed with the simple common composition that is easy to get, proportioning is convenient, meanwhile will inevitably bring the simplification of technique and program, simplify the operation, the convenient use is beneficial to and produces and use very much.
