Abstract
The invention discloses an easy-to-recognize sunproof garbage bin and a manufacturing method thereof and belongs to the technical field of daily supplies. The easy-to-recognize sunproof garbage bin is structurally composed of three layers which are complementary in performance, singular in function and diversified and comprises an inner protection layer, a base layer and an outer coating layer, the inner protection layer features in scale preventing and deodorizing; the base layer is a garbage bin body and is inwardly connected with the inner protection layer and outwardly connected with the outer coating layer; the outer coating layer plays a role in performance optimization and functional diversity and is the main part for realizing the easy-to-recognize function. By the unique functional structure and material components, the garbage has an obvious illuminating effect in dim light, and the problem that the garbage bin is blurred at night and hard to recognize is effectively solved; the garbage bin has good properties of sunproofness, corrosion protection and the like, and the easy-to-recognize sunproof garbage bin is structurally composed of three layers which are independent, so that problems that coating simply coated is easy to peel off and the like are avoided.
Description
Technical field
The invention belongs to articles for daily use technical field is and in particular to a kind of sun-proof dustbin easy to identify and preparation method thereof.
Background technology
Dustbin, also known as litter-bin or dustbin, can be divided into plastic garbage bin, stainless steel dustbin, wooden rubbish by saw lumber
Rubbish bucket, metal dustbin etc..In recent years, because the packaging such as varieties of food items, product is increasingly taken seriously, the thing followed is bag
Dress waste product (candy skin, packing box etc.) gets more and more, and gives people easily simultaneously, to create the rubbish of enormous amount in band, if
Do not reclaim or concentrate accumulation, wantonly abandon, then can affect urban environment, give people life and bring tremendous influence.And dustbin is then
House refuse can be concentrated, environmental protection personnel can focus on, and substantially increases operating efficiency.Therefore, dustbin becomes municipal portion
Door particularly one of regular supplies of concern, rationally place dustbin, can not only reduce municipal pollution moreover it is possible to improve civic environmental protection meaning
Know, there is very high social effectiveness.
Because the dustbin overwhelming majority is placed in open air, stand to expose to the weather, rain beats the weathers such as freezing, therefore dustbin
Saw lumber requires sun-proof, antifreeze, waterproof modulation characteristic.At present, due to the fast development of plastics industry, existing plastic garbage bin is substantially all
Possesses above-mentioned characteristic.In addition, conventional garbage bucket also progressively develops to Wood-plastic material direction it is intended to reduce dirty further
Dye.But there is common defect in current dustbin, night no light-illuminating when, dustbin is difficult to recognize, main reason is that existing
Have outside dustbin and finish pigment no-reflection layer or no storage light function, in dark smudgy it is difficult to identification, be that citizen bring
Worried.But conventional garbage bucket only realizes function easy to identify it is clear that there are problems by outer painting reflecting coating, such as long-term
Stand to expose to the weather, the weather such as the frost that drenches with rain, coating property then requires very high, there is no the correlation that can meet above-mentioned requirements at present
Coating；And, coating suffers from bad weather for a long time it may appear that weathering was lost efficacy, and the phenomenon such as come off.Summary is although part applies
Material has reflective or storage light function, also has good cohesive with dustbin matrix, but existing coating cannot meet higher work(
Energy and performance requirement, and simple spraying function coating is easily caused the phenomenons such as paint, weathering, and follow-up maintenance workload is big.
Content of the invention
It is an object of the invention to：Overcome conventional garbage bucket impalpable defect in dark, solve existing work(
Easily the problems such as paint, easy-weathering can be fallen after the simple spraying of coating, thus providing a kind of sun-proof dustbin easy to identify and preparation method thereof,

It is a further object of the invention to provide the preparation method of described sun-proof dustbin a kind of easy to identify, specifically
Step is as follows：
Prepare sheath：PVC resin powder, DOA plasticizer, scale preventative, ACR processing aid and titanium dioxide are ground to respectively
Powder, after being sufficiently mixed, adds epoxidized soybean oil, fire retardant HBB, is warming up to 110～130 DEG C, maintains temperature 1～2 little
When, then gradually it is cooled to 70～80 DEG C, add emulsion polyvinyl chloride resin, after stirring mixing, maintain temperature 15～30 minutes, then
It is cooled to 30～40 DEG C, continue stirring until half suspended state standby；
Prepare base layer：After waste PVC aggregate, waste and old PE crushed material, waste PP crushed material are sufficiently mixed, it is warming up to 70
～80 DEG C, add EVC compatilizer, maintain temperature 20～30 minutes；Add DOP plasticizer, organic tin stabilizer, CPE processing
Auxiliary agent, CA antioxidant, coupling agent, are warming up to 100～110 DEG C of mixing high-speed stirred 30～40 minutes；Add PE-g-MAH to stir
Mix 10～15 minutes；To 30～40 DEG C, cooling extent is 0.2 DEG C/min to slow cooling；Then gradually heat up 70～80 DEG C, lead to
Cross extruder for shaping；
Prepare external coating：After described composition of raw materials is sufficiently mixed, it is warming up to 80～100 DEG C, maintain temperature 30～40
Minute, then curing molding.
Bonding：Sander is passed through on the base layer two sides of preparation, after polishing is coarse, brushing a layer of adhesive, then will be interior
Sheath, external coating are bonded to base layer successively and can prepare dustbin of the present invention.
Further, described sheath, external coating and base layer pass through adhesives.
Further, when described sheath is bondd with base layer, sheath becomes half suspended state, and base layer is solid-state.
Further, when described sheath is bondd with base layer, first with sander, matrix layer surface is polished crude, be allowed to
Form rough surface texture, the binding agent being then 70～75 DEG C by temperature is painted on its surface, then temperature is 35
～50 half suspended state sheaths are overlying on the binding agent of base layer, solidify under 1.5kpa pressure.
Further, when described external coating and base layer bond, first with sander, polished hair in base layer, external coating surface
Rough, it is allowed to form rough surface texture, then by crude surface docking compacting, then pour binding agent into joint
Place, after place to be joined gap completely fills out, standing makes adhesive solidify.
Dustbin of the present invention is by function is different, performance complement, and relatively independent and combine closely three layers are adhesion-molded
, compared with conventional garbage bucket, its advantage is：
1) present invention is mutually piled up using three-decker and forms, sheath mainly with antiscale, deodorant based on, base layer be
Frame, sheath is coupled together with external coating, and external coating is mainly functional layer, and Main Function is storage light, reflective, realizes easy to identify
Functional effect；Three-decker is solid-state and connects, it is to avoid coating is simple spray after easily drop, the problem that easy-weathering lost efficacy；
Three-decker is connected by adhesive, solves the problems, such as smell weight after coating spraying.
2) when sheath of the present invention is bondd with base layer, sheath is half suspended state, due to crude matrix layer surface knot
Structure and the effect of high-temperature adhesives, and half suspended state has certain mobility so that concavo-convex place dispersion different amounts of half is hanged
So that sheath is combined with base layer more closely, protect the substrate layer is not corroded, destroys float.
3) when external coating of the present invention is bondd with base layer, external coating is solid-state, and because external coating is functional layer, optimum is whole
Body bonds, so that what static structure was not affected by factors such as temperature when boning, thus ensureing its storage light best performance.
