Description
Technical field
The present invention relates to a kind of flowerpot and preparation method thereof, a kind of specifically degradable environmental protection type flowerpot and preparation method thereof.
Background technology
Along with socioeconomic fast development, people's life becomes increasingly abundant colorful, decorates red-letter day and life at ordinary times changes daily need into from fashion with flowers.In Europe, flowers have become the important component part of plant husbandry, and various countries' seedling flowerpot and potted plant flowerpot demand increase severely.These situations prove absolutely that floral art has become an indispensable part in people's daily life.Present flowerpot is of a great variety, and as traditional potter's clay flowerpot, jardiniere, Wooden flower pot, plastic flowerpot etc., these flowerpots all have shortcoming separately.Flowerpot, the frangible difficult transportation of jardiniere on the pottery; Wooden flower pot costs an arm and a leg; Though plastic flowerpot is light and handy durable but waterproofly do not seep water, and is difficult to adapt to flower growth, and can not degrades fully for a long time at occurring in nature, thereby leave a legacy of trouble to the earth, causes " white pollution " serious to the earth.For this reason, people attempt to develop a kind of energy natural degradation, the comparatively simple environmental protection type flowerpot of production technology always.Flowerpot made of plant fibres is exactly one of environmental protection type flowerpot of energy natural degradation.
Number of patent application is: 01113233.7, publication number is: the Chinese patent of 1393122A discloses a kind of vegetable fiber floral disc and manufacture method thereof, be to be adhesive with the urea-formaldehyde, its shortcoming is that degradation property is poor, be difficult to degrade fully, there is excessive free formaldehyde easily in the product simultaneously, may influences the growth of plant.
Number of patent application is: 200510100879.8; publication number is: but the Chinese patent of CN 1771784A discloses a kind of environmental protection floral disc and manufacture method thereof of natural degradation, and adhesive is one or more in starch, polyvinyl alcohol (PVA), polycaprolactone (PCL) or the aminoplast molding powder.Starch is a kind of common adhesive, and by its product poor water resistance of making, intensity is also not enough.Polyvinyl alcohol (PVA) also is the adhesive of using always, but its poorly water-soluble.Aminoplast molding powder is powdery, and the energy consumption height need to add the filler that is easy to moulding such as spent pulping liquor starch etc. in dry run, and active ingredient is low, the cost height, and degradation property is poor, is difficult to degrade fully.In addition, its manufacturing process has the water conservancy project of adding preface, thereby causes the mixture moisture height, is prone to bubble, cracking in the high temperature pressing process.This shows up to the present, but also do not have a kind of environmental protection type flowerpot and preparation method thereof of natural degradation of real practicality.
Summary of the invention
But the objective of the invention is to propose a kind of natural degradation, but deflection is good, intensity is high, the environmental protection type flowerpot of on-deformable natural degradation and preparation method thereof.
Purpose of the present invention can be achieved through the following technical solutions:
But the environmental protection type flowerpot of natural degradation; its component comprises vegetable fiber powder and adhesive; the percentage by weight of vegetable fiber powder is 50%～70%; the percentage by weight of adhesive is 30%～50%; the vegetable fiber powder comprises powdered rice hulls, bamboo powder and bean powder; the percentage by weight that powdered rice hulls accounts for the vegetable fiber powder is 40%～70%, and the percentage by weight that the bamboo powder accounts for the vegetable fiber powder is 10%～40%, and the percentage by weight that bean powder accounts for the vegetable fiber powder is 20%～30%.
But the preparation method of the environmental protection type flowerpot of natural degradation may further comprise the steps:
1. after vegetable fiber being pulverized, cross 60～120 mesh sieves, get sieving materials;
2. sieving materials and adhesive are put into mixer mix compound;
3. compound and releasing agent are continued to mix in 100: 0.5～2 ratio, must the mold pressing compound;
4. the mold pressing compound is taken out from mixer, dewater, moisture control≤15% gets molding compound;
5. molding compound is put in 130～160 ℃ the mould, pressure is 15～30MPa, and the press time is 40 seconds～150 seconds, and wherein exhaust is 1～3 time, formed product;
6. take out shaped article, treat to grind off overlap after product fully cools off, accomplish fluently the osculum of flowerpot bottom.
Purpose of the present invention can also further realize by following technical measures:
But the environmental protection type flowerpot of aforesaid natural degradation; wherein said adhesive is the mixture of oxidized starch, isocyanates and modified aminoresin; the percentage by weight of each component is: oxidized starch 20～40%, isocyanates 10～70%, modified aminoresin 10～70%.
But the modifier that adds in the environmental protection type flowerpot of aforesaid natural degradation, wherein said modified aminoresin is ash, and the percentage by weight that ash accounts for modified aminoresin is 1%～10%.
But the preparation method of the environmental protection type flowerpot of aforesaid natural degradation, wherein said step 4. in, dehydration temperaturre is 75～85 ℃.
But the preparation method of the environmental protection type flowerpot of aforesaid natural degradation, wherein said step 3. in, releasing agent is an OPE.
Advantage of the present invention is: vegetable fiber powder of the present invention is selected the mixture of powdered rice hulls, bamboo powder and bean powder for use, and powdered rice hulls is cheap, golden yellow color, is easy to moulding.Bamboo powder exquisiteness is smooth, and product strength height, the fineness made are good.Bean powder is the main conditioning agent of degradative phase, and the addition of bean powder is high more usually, and degradative phase is short more.Adhesive is the mixture of oxidized starch, isocyanates and modified aminoresin, and prescription rationally.Add ash modifier in the modified aminoresin, after modification, can improve the softness of adhesive, fragility is reduced, increase flexible, resistance to water, improve the freedom from cracking ability, increase adhesion strength, improved the frangible characteristics of ageing-resistant performance and product.And by the adhesive that oxidized starch, isocyanates and modified aminoresin mixture are formed, be a kind of adhesive of environment-friendly type, can guarantee the intensity of flowerpot made of plant fibres, can guarantee the resistance to water and the toughness of product fine again.Simultaneously can biological degradation, reduce environmental pollution.Making in the flowerpot process has increased high temperature dehydration technology, because paddy meal, bamboo powder do not have long stapled existence, bond together and have intensity preferably densely, and except adhesive will reach certain requirement, the influence of moisture was most important.Moisture height, product are prone to bubble, cracking in the high temperature pressing process; Moisture is low, and it is poor to cause molding compound to flow, and it is complete to be difficult to moulding, moisture is controlled at≤15%, can make pressing process not be prone to bubble, cracking, moulding fully.Therefore, degradable environmental protection type flowerpot of the present invention has following characteristics: (1) profile exquisiteness, any surface finish, color and luster is soft, quality is fine and smooth; (2) deflection is good, intensity is high, not yielding, be convenient to transportation and use; (3) temperature difference accommodation is big, stable performance between-20 ℃～100 ℃; (4) antiseep is good; (5) withstand voltage 〉=50kg, heatproof 〉=100 ℃, moisture content≤10%; (6) flowerpot can be at the natural world natural degradation after using, degradation property 〉=IV level.
