Abstract
The present invention is composite material menhole cover series protuct and preparation method thereof.Use following raw material: with plastic waste (polyethylene, polypropylene all can) 30～40% and industrial residue (boiler bottom slag, ladle slag, cast waste sand etc.) 60%～70% is base-material, water glass is 3～8% of a base-material total amount, Graphite Powder 99 is 0.2～1% of a base-material total amount, and tertiary sodium phosphate or other phosphorous phosphorus compound are 0.1～0.5% of base-material total amount.Preparation by the following method: raw material is smashed, various raw materials by proportional quantity place in the mixer mix after, carry out thermal synthesis, the thermal synthesis temperature is 160 ℃～230 ℃, and the material after the thermal synthesis enters mould inner pressure system, pressure 〉=22MPa, 15～30 minutes dwell times, depanning gets product.The product that the present invention produces have lowly pollute, low-cost, characteristics that quality product is high.
Description
Technical field
The present invention relates to a kind of composite material menhole cover series protuct that utilizes the waste and scrap preparation and preparation method thereof.
Background technology
The patent No. is the patent of invention of ZL00109927.2, " a kind of regenerated composite material and preparation method thereof " disclosed, this patent is the applicant's patent of first to file again, the prescription of this patent and production technique, produce secondary pollution in process of production, influence environment, quality product is wandered low-grade row, problems such as cost is high make the benefit of enterprise can not get improving, environment has been subjected to pollution.
Summary of the invention
The purpose of this invention is to provide a kind of matrix material that utilizes the making well lid that plastic waste, industrial residue etc. produce and preparation method thereof, it have lowly pollute, low-cost, characteristics that quality product is high.
For quality product, the benefit that makes enterprise is improved, environment is protected.Make joint efforts through the technician of our unit, study repeatedly, test, search out the new prescription of a cover, novel process.
Prescription of the present invention and preparation method (technology) are as follows:
Prescription: with plastic waste (polyethylene, polypropylene all can) 30～40% and industrial residue (boiler bottom slag, ladle slag, cast waste sand etc.) 60%～70% is base-material, water glass is 3～8% of a base-material total amount, Graphite Powder 99 is 0.2～1% of a base-material total amount, and tertiary sodium phosphate or other phosphorous phosphorus compound are 0.1～0.5% of base-material total amount.
The technological process of production: smash → batch mixing → synthesize → press shape → check warehouse-in.
The preparation method: raw material is smashed, various raw materials by proportional quantity place in the mixer mix after, carry out thermal synthesis, the thermal synthesis temperature is 160 ℃～230 ℃, and the material after the thermal synthesis enters mould inner pressure system, pressure 〉=22Mpa, 15～30 minutes dwell times, go out to be molded as menhole cover series protuct.
New prescription of the present invention and novel process compared with prior art have following positively effect:
1, stops secondary pollution, protected environment.Original formulation uses waste oil to make lubricant, and its composition is quite complicated, includes the various inorganic salt that are activated, organic salt and a large amount of radicals.Therefore, in the heat seal process process, can give out the dense smoke of a large amount of Huangs, black, produced the smell that makes us the perverse nose of feeling sick in a large number: a large amount of sulfurous gas, hydrochloric acid, phosphoric acid and some organic molecule smells fill the air in air, are endangering the healthy of direct labor and surrounding resident.The present invention uses water glass to make lubricant, because new prescription all belongs to mineral compound, does not have radical to exist, generally can not the activated inorganic compound under the temperature of spending 200 ℃ more, so, in the thermal synthesis technological process, be more stable.Therefore, there is not generation poisonous, obnoxious flavour in process of production; There is not the generation of the dense smoke of a large amount of Huangs, black yet.Through the experiment of three months new prescriptions and novel process, without waste oil.Thoroughly stopped generation poisonous, obnoxious flavour from the source, reduced the pollution to environment, the protection workman's is healthy.
2, reduce cost, increased the benefit of enterprise.Because original formulation uses waste oil to make lubricant, and waste oil price height, per 3.30 yuan/kg uses in 5～9% ratios, and every 100kg raw material needs 16.5～29.7 yuan of Renminbi.Adopt new prescription to use water glass to make lubricant, the per 0.50 yuan/kg of water glass uses in 3～8% ratios; Every 100kg material needs 1.5～4 yuan of Renminbi, uses Graphite Powder 99 0.2～1%, and by 1 yuan/kg, every 100kg raw material needs 0.2～1 yuan of Renminbi; Use tertiary sodium phosphate 0.1～0.5%, by 1.5 yuan/kg, every 100kg material needs 0.15～0.75 yuan of Renminbi.Three additions add up to 1.85～5.75 yuan of Renminbi by every i00kg raw material.By above comparative analysis as can be known, every 100kg material ratio reduced cost 10.75～27.85 yuan with waste oil originally.Annual cost-saved about 12.9～33.4 ten thousand yuan (in every month 100 tons of materials).
3, improved quality product.Light-duty well lid with original prescription and explained hereafter can only bear 17～23Mpa pressure, and bearing pressure only has about 10～13 tons.And adopt after new prescription and the novel process, the light-duty well lid of being produced can bear 27～37Mpa pressure, and bearing pressure is the 15-21 ton, and bearing pressure is than 2～11 tons of the highest bearing pressure improves originally.Heavy well lid can bear 45～50Mpa pressure, and bearing pressure is 25～29 tons, reaches and surpass the standard of 24 tons of national regulations.Visual appearance is more attractive in appearance than original.
