Abstract
The invention discloses a method for preparing an anti-corrosion drain pipe from solid waste, that is, a method for manufacturing an underground drain pipe by taking solid waste such as building garbage as a raw material and adding a through high polymer. The method mainly comprises the following steps: screening a polymer, subsequently adding a through cross-linking agent to perform through reaction, standing the through high polymer to be cooled down and crushing for later use, blending the through high polymer with hot-molten solid waste, finally forming the mixture in a hot casting mode, cooling down and demolding to obtain a finished product. By adopting the method, the burden in city building waste treatment is alleviated, recycling of resource is achieved, a scientific treatment method for environment-friendly waste treatment is provided, zero emission of city building garbage is realized, and great environment benefits and social benefits are achieved.
Description
Technical field
The invention belongs to the Infrastructure field of building, mainly relate to a kind of preparation method of corrosion resistant sewer line.
Background technology
Along with environmental problem is taken seriously gradually, energy-saving and environmental protection become the development topic of world's environmental protection.Current, environment sustainable development problem has become the important topic of countries in the world environmental science Experts ' Attention and research.
Municipal drainage facility is the indispensable important infrastructure of modern city, is that anti-the harnessing the river in city polluted and get rid of urban ground water, guarantees the major project of the normal productive life in city.Urban drainage pipe network is again important component part in pumping equipment, along with the increase of municipal sewage treatment amount, and the enlarging in city and the reconstruction of underground works, buried drain pipe net will spread all over the place.According to Ministry of Construction scholarly forecast ， Tenth Five-Year Plan Period China, in the increase rate of investment aspect water supply and draining, will continue higher than country's fixed asset investment rate of increase." during "the 10th five-years" " China will enter the climax of building network of drains, and becomes one of social investment focus.
At present China 80% adopts reinforced concrete pipe completely in buried drain pipe field, and this Steel Concrete outfall sewer is easy to leak the problem that pollutes public hazards and has caused attention.Modern society's life is used the waste discharges such as various washing composition, sanitising agent that concrete drain tile is more easily corroded, particularly my district belongs to coastland, and cement sewer pipe net, due to the erosion of seawater and wastewater from chemical industry, concrete duct is corroded more seriously, and municipal drainage problem is more and more outstanding.The underground pipe network draining that ensures city is smooth and easy, just must consider its etching problem.This project is carried out development for the corrosion-resistant outfall sewer critical material of solid waste system, project implementation, can capture, realize the regeneration comprehensive utilization of the solid waste such as building waste, its enforcement and popularization, sewer line particularly sea-water area and the beneath corrosion-prone problem of pipeline of chemical plant periphery can have been solved, can effectively alleviate the solid refuses such as a large amount of urban architecture rubbish and dump slag and process significant stress and the burden of bringing to urban environmental protection, impel urban architecture rubbish to realize zero release and become possibility.It is not with an organic solvent environmentally friendly machine simultaneously.
Summary of the invention
For the problems referred to above, the invention provides and a kind ofly using the solid waste such as building waste as raw material, add the method that superpolymer is made subsoil drain that runs through of preparation, the key step of the method has:
1) screening polymkeric substance: comprise erosion resistance, bridging property, film-forming properties and mutual penetrability;
2) according to the polymkeric substance of selecting, select crosslinkedly to run through agent and run through reaction;
3) run through reaction finish after by material put to cooling, pulverize standby;
4) will after solid waste material hot melt, be mixed with the reactant of step 3);
5) by the hot cast molding of the mixture of step 4), then cooling and demolding finished product.
In the present invention, polymkeric substance used is polyethers, poly cyanamid, polypropylene, isocyanic ester, urethane, vinylbenzene or epoxy resin.
Crosslinked described in the present invention to run through agent can be polyisocyanates, polyalcohols or polypropylene glycol glycidyl ether etc.
The material of solid waste described in the present invention is urban architecture rubbish or dump slag solid refuse.
Weight proportion between stock polymer described in the present invention and solid waste is 1:3-5.
The weight percent that described in the present invention, the crosslinked consumption that runs through agent accounts for polymkeric substance is 0.02-0.6%.
Beneficial effect:
(1) do not use cement steel to make sewer line, and use the heat curing-type polyblend of preparation as the main body matrix material of sewer line;
(2) as this superpolymer coating of corrosion resistant coating, be that solid powder paint is not with an organic solvent made thinner, belong to environment-friendly type coating;
(3) its uses urban architecture rubbish, and the solid residue after abandoned mine rubble and city garbage burning is as aggregate, make corrosion-resistant under waterpipe, realized the comprehensive utilization of resource;
(4) this kind of material has excellent freezing and thawing performance and can rapid shaping.
The core of this invention is to using the solid waste such as building waste as raw material, adds the freshly prepd superpolymer that runs through and makes subsoil drain, has solved the burden of urban architecture refuse treatment, and has realized the regeneration of resource.For environmental protection offal treatment provides the treatment process of science, making urban architecture rubbish realize zero release becomes possibility, and environmental benefit and social benefit are remarkable.
Running through by interpenetrating polymer networks method between the polymkeric substance in the present invention realizes, and is prior art.
