Abstract
A kind of waste sand-slag composite, it is with foundry's antiquated sand, slag, dust, mud are primary raw material, are binding agent with waste plastics film, waste plastic product, a kind of nonmetallic materials that are combined into through certain technology.Have processing characteristicies such as saw, nail, brill, plane, have the anti-folding that is higher than cement products, tension, resistance to compression, physical and mechanical property such as shock-resistant again, also have multiple performances such as waterproof, anticorrosion, easy-formation.Can be in extensive fields replacing wood, cement, plastics, steel etc.Can be in order to make packing case, splash guard, corrosion protection plate, guardrail board, sound panel, corrugated tile, sleeper, furniture, drainpipe etc.
Description
Waste sand-slag composite is a kind of nonmetallic materials.
A large amount of antiquated sands, slag, dust, mud will be got rid of every day by foundry, transport the severe contamination workshop condition if can not in time clear up, and hinder production operation, even can transport the pollution that also can cause another ground, and also not only expensive but also take up an area of.Set up and a kind ofly have only raw material to transport, product transport and not the case type foundry of discharge waste be the effective way of condensation improvement, changing waste into valuable.
Along with the universalness day by day of plastic products, the discarded object of the plastic package material in various industrial or agricultural and the life, mulch film, goods etc. has become the main constituent in city and rural garbage.The simple regeneration of these discarded objects is subjected to plastics variety, color and condition restriction such as not comtaminated.If with its as binding agent, the refuse that is used for solidifying other industries will be at one stroke two environmental practices.
Silicon dioxide microparticle in antiquated sand, slag, dust, the mud has very high physical and mechanical property, waste plastics then has performances such as good toughness, water-fast, corrosion resistant, easy-formation, these two kinds of waste materials is combined, and has synthesized a kind of new material with multiple material property.It has multiple performances such as timber, concrete, plastics, steel.By international online retrieval, consulted ESALL document and DIAL 350 with 351 documents, all find the patent identical with content of the present invention.
The objective of the invention is various antiquated sands, slag are mixed the waste plastics that is complementary with it, pass through certain processes, be combined into a kind of novel metalloid material, so both digested the waste plastics in the refuse of foundry and city, the rural garbage, produced a kind of composite again with timber, concrete, plastics, the multiple material property of steel.
This composite-material formula and manufacture craft are: classification such as antiquated sand, slag, dust, mud are collected, made it be dried to water content below 3% with nature and artificial method, then it is crushed and screened and obtain diameter less than 0.5 millimeter raw material, the classification storage is standby.The various waste polyethylenes of collecting, the goods of waste polypropylene or waste polyvinyl chloride, letter sorting is sorted out, and cleans to surface attachments to be less than 1%, and it is standby less than 5 millimeters material, storage to shred granulating group then.
Get antiquated sand, slag and plastics according to antiquated sand: plastics=1～5: 1 cooperates, mix in the input kneading machine, temperature is controlled at 100～200 ℃, incorporation time with till evenly kneading into granule, the mixture adding temperature of kneading good is controlled in the interior extruder of 150～300 ℃ of scopes pushes with sticky pasty state, and its form gets final product being full of die cavity under pressure.Extrudate is if use then pressure limit 50～250 kilograms per centimeter of forcing press moulding
2, water cooling is promptly used in pressurize 1～5 minute after the depanning.Extrudate is if then can depress to sheet material less than 6 millimeters 0.12～2.4 meter/minute hauling speed with the calender moulding.
This manufacturing process flow is shown in Figure of description 1.
Advantage of the present invention and good effect are the methods that a kind of existing social benefit of foundry's changing waste into resources is had an economic benefit again, and it makes in the past casting refuse become today and makes a kind of cheap price and excellent quality raw material of nonmetallic composite in the future; It has been eliminated public hazards, has enlarged the production area, has improved labor productivity; It has saved the spending of discharge waste, has increased a pair industry income, has solved surplus labor; It has promoted the lateral ties between each industrial department, for development frontier science technique functions pivotal role.
This composite had both had the processing characteristicies such as the saw, nail, brill, plane of timber, had again the anti-folding that is higher than cement products, tension, resistance to compression, the physical and mechanical property such as shock-resistant, also had the multiple performances such as the waterproof of plastics, anticorrosion, easy-formation. Its raw material sources are extensive, cheap, manufacturing process simple, produce the duration weak point, can replace the materials such as timber, cement, plastics, iron and steel. Can in order to make packaging boxboard, splash guard, corrosion protection plate, guardrail board, sound panel, corrugated tile, Sleeper, furniture, drainpipe etc.
Embodiment:
With the waterglass antiquated sand 45% of certain foundry, water content is below 1%, granularity 50 orders; Electric arc slag 30%, water content be below 1%, granularity 100 orders; Waste plastics film 25%, after kneading under 200 ℃ of temperature, clamp-on model, in 200 kilograms per centimeter
2Be pressed into 100 * 50 * 50 millimeters plate under the pressure, pressurize promptly obtained this kind composite with the cold water chilling after 5 minutes.Its proportion 1.56, compression strength 320 kilograms per centimeter
2, bending strength 250 kilograms per centimeter
2, water absorption rate 0.05%, in 0.1 gram equivalent of hydrochloric acid and 0.1 gram equivalent of sodium hydroxide solution, respectively soak 48 hours after, not finding does not have the corrosion situation, can cut easily with saw, and energy firm hammer into nail, be screwed into wood screw, it is wrinkle resistant to brush paint back, can keep the gloss that paints.
In place with good conditionsi, adopt fresh sand to make raw material, process conditions are constant, and the every performance of the sheet material that makes all meets or exceeds the antiquated sand goods, and desirable color and luster is arranged, and provides better condition to design decorative pattern, color.
Claims (2)
1, a kind of waste sand-slag composite is characterized in that:
(1) composition of raw materials waste sand-slag: waste plastics=1～5: 1,
(2) technological process of production and process conditions are waste sand-slag to be collected be dried to moisture content below 3%, crushing and screening to grain diameter is stocked stand-by less than 0.5 millimeter, waste plastics is classified, removing the surface adhesion thing makes it less than 1%, chopping to grain group stocks less than 5 millimeters, two kinds of materials that prepare are proportioned, add in the kneading machine mixing under 100～200 ℃ of temperature, knead, incorporation time is with till evenly kneading into granule, then mixture adding temperature is controlled in 150～300 ℃ of extruders in the scope and extrudes, in 50～250 kilograms per centimeter with sticky pasty state
2Forming under the pressure, pressurize 1～5 minute is gone into water cooling and is got product after the depanning.
2, composite as claimed in claim 1 is characterized in that making raw material with fresh sand and new polyethylene, polypropylene, polyvinyl chloride.
