Abstract
The invention discloses a sound-absorbing ceramic plate using kitchen waste as raw material and preparation method thereof. Through a drying process, organic matter of kitchen solid waste ecological material are used as raw material, charring in a high temperature nitrogen protective stove to form porosint. Smashing charring matter then adding with pore forming agent such as eleaostearic acid, oxene resin and PVC resin powder, the mixture is mixed fully through uniform stirring and supersonic wave oscillation. After oscillation, the mixture material is filled in a molding cavity under pressure, then putting into an oven to cure; a sound-absorbing ceramic plate is got after natural cooling. The preparation technology of the invention is simple, has low cost, raw material is kitchen waste, can get harmless rubbish with decrement, resource treatment when getting sound-absorbing ceramic plates. The sound-absorbing ceramic plate can be applied to construction business and decoration field.
Description
Technical field
The present invention relates to solid waste disposal, particularly a kind of is the sound absorption ceramic panel and preparation method thereof of raw material with the food waste.
Background technology
Current society, environmental problem becomes increasingly conspicuous, and the shortage of resources problem also is on the rise.How can turn waste into wealth, to make the resource recycling, this receives the concern of various circles of society.
Food waste comprises various organic wastes such as leftovers, leftovers, dish leaf, pericarp and packing bag, and the ratio that it accounts for domestic refuse is about 30%～40%.Food waste is nutritious, once is the feed of having raised pigs, but unprocessedly has the pathogenic microorganism probably.After " prohibiting will uses hogwash to feed live pig " expressly issued, recycling became key.
At present, the main processing mode of food waste has and pulverizes in line method, biological treatment and make several method such as feed.Pulverize in line method and only be only applicable to the little unit of changing food waste output, easily produce sewage and foul smell when handling, grow germ, mosquitos and flies and cause pathophoresis, greasy dirt condenses into piece and can cause water shoot to stop up, and reduces the drainability of municipal sewage system.Biological treatment processing costs height, and be not suitable for go mouldy, seriously rotten and handled by the food waste of chemical pollution, in order to avoid pollute derived product.The food waste of making feed can not go bad, and also needs food waste is classified, because food waste is mixed with various impurity (napkin paper, chopsticks, the disposable tablecloth etc.), the letter sorting difficulty is big.In a word, the treatment technology of existing food waste all has its limitation, and resource utilization degree is not high.
Summary of the invention
The object of the present invention is to provide a kind of is the sound absorption ceramic panel and preparation method thereof of raw material with the food waste; processing by the ecomaterial that given up admittedly in the kitchen; making organism wherein carry out charing formation porous material in high temperature nitrogen protection stove, is that matrix goes out sound-absorbing porous material by formulation again with the porous material.
The objective of the invention is to realize by following technical scheme:
1, a kind of is the sound absorption ceramic panel of raw material with the food waste, and prescription is by weight percentage:
Porous carbide 30～40%;
Stearic acid 10～30%;
Polyvinyl chloride resin powder 20～25%;
Epoxy vinyl resin 20～25%
2, a kind of is the preparation method of the sound absorption ceramic panel of raw material with the food waste, and the step of its preparation is as follows:
1) with the food waste of collecting through shredding, combination treatment is placed in the thermostatic drying chamber, keeps 10～12 hours down at 105 ± 1 ℃, treat the food waste oven dry after, it is ground into 3～5mm size;
2) rubbish of getting after oven dry is pulverized carries out charing in the nitrogen protection stove, keep furnace pressure at 0.10～0.15MPa, begin heating from normal temperature, just begin heat-up rate and be controlled at 2～3 ℃/min, treat to keep when temperature is elevated to 120～150 ℃ 15～20min, be warmed up to 600～800 ℃ with 1～2 ℃/min then, kept 60～80 minutes; It naturally cools to room temperature relief, makes the porous carbide.
3) carbide being pulverized is 1～2mm size, by weight percentage again with porous carbide 30～40%; Stearic acid 10～30%; Polyvinyl chloride resin powder 20～25% and epoxy vinyl resin 20～25% are through evenly stirring and ultra-sonic oscillation make the mixture thorough mixing; Put into mould, put into 280～300 ℃ baking oven, kept 1～2 hour, make its curing; After treating its naturally cooling, obtain sound absorption ceramic panel.
The beneficial effect that the present invention has is: the sound absorption ceramic panel that utilizes the present invention to prepare, technology is simple, with low cost, and prepared using is food waste, when making sound absorption ceramic panel, can reach to rubbish innoxious, minimizing, the requirement of recycling treatment.Prepared ceramic panel can find application in fields such as construction industry and adnornment industry.
