Abstract
The invention relates to a new use of polyurethane hard bubble, which in detail is used as filling materials for the rejuvenating and curing of told and good trees in the tree holes. The application of the said polyurethane hard bubble in the tree rejuvenating and curing is realized by the following steps: connecting the concrete iron and iron wire to indefinite shape and putting it into the tree hole as inner support; mixing and stirring the liquid of blowing agent- isocyanate and polyether with the proportion to be 1:0.5-1.5; pouring the mixture mentioned above into the tree hole with 70-300 kg per cubic meter; fixing and sealing with preformed mold in the out, pressing bark line in the top or spiking one layer of real bark. The invention is characterized by the following aspects: water resistance, antiseptic, compression, wind resistant, resistant to flame, long working life, near contraction and expansion with the tree, elastic, the effective prevention of the continuing tree rotting and damage by the compact association with the tree, little influence of the tree growth, beautiful and simple shaping process.
Description
[technical field]
The present invention relates to the purposes of hard polyurethane foam, relate in particular to the purposes in ancient and well-known trees rejuvenation and maintenance.
[background technology]
Polyurethane is a kind of emerging high-molecular organic material, is described as " the fifth-largest plastics ", because of its remarkable performance is widely used in the national economy various fields.Product is used and is related to fields such as light industry, chemical industry, electronics, weaving, medical treatment, building, building materials, automobile, national defence, space flight, aviation.
Hard polyaminoester rigid foam plastic wherein, be called for short hard polyurethane foam, mostly be hole-closing structure, have that insulation effect is good, good waterproof performance, in light weight, good characteristics such as specific strength big, easy construction, also have characteristics such as sound insulation, shockproof, electric insulation, heat-resisting, cold-resistant, anti-solvent simultaneously, be widely used in the heat-insulating material such as casing heat insulation layer, freezer, refrigerator car of refrigerator, refrigerator-freezer, building, storage tank and pipe insulation material, be used for nonadiabatic occasion on a small quantity, as imitative timber, packaging material etc.Generally speaking, more low-density hard polyurethane foam is mainly as heat insulation (insulation) material, and the hard polyurethane foam of higher density can be used as structural material (imitative timber).
The main application of hard polyurethane foam has the following aspects: the one, and industry refrigerating equipments such as food, as refrigerator, refrigerator-freezer, freezer, refrigerator car etc., hard polyurethane foam is the optimal heat-insulating material of refrigerating equipment; The 2nd, the industrial equipment insulation is as storage tank, pipeline etc.; The 3rd, construction material, in American-European developed country, hard polyurethane foam for building accounts for about half of the total flow of hard bubbling, be more than times of the consumption that hard bubbles such as refrigerator, refrigerator-freezer, in China, it is also general unlike western developed country in the application of building industry to hard bubble, so the potentiality of development are very big; The 4th, transportation is as automobile calash, inside gadget etc.; The 5th, imitative timber, high density (density 300～700kg/m
3) hard polyurethane foam or glass fiber reinforced unplasticised bubble be the structure rigid foam plastic, claim imitative timber again, have intensity height, good toughness, characteristics such as the skinning densification is tough and tensile, moulding process is simple, production efficiency height, the comparable natural timber height of intensity, the comparable natural timber of density is low, and alternative timber is as all kinds of high-grade goods; The 6th, Embedding Material etc.
Ancient and well-known trees are through the very long years, the wound that its limb has artificially unavoidably, natural cause causes, the long-term disunion of wound that causes because of a variety of causes, the xylem that exposes is for a long time flooded by rainwater, rot gradually, form treehole, trunk inner hollow when serious, bark breaks, general appellation " paunch ".Because the xylem of trunk and marrow rot, conducting tissue is destroyed, thereby influences the transportation and the storage of moisture and nutrient, also can cause the further procreation of germ, enlarge the area that festers, seriously undermine tree vigo(u)r, reduce the robustness and the load capacity of limb, shortened the tree body life time.In order to prevent that treehole from continuing to enlarge and development, make trunk more firm, reach the purpose of rejuvenation, will in time take the cotree hole and reinforce the measure of supporting.
The past routine is repaired treehole with cement, but cement alkalescence is too strong, and day can come off again long afterwards simultaneously, and a large amount of bacteriums, germ are invaded and set body, still can influence the ancient tree growth.Past is conventional with steel pipe or build a framework and do the externally reinforced support of trunk, both takes up room, and is not attractive in appearance again.
Along with science and technology development, increasing of new material particularly, resist technology is greatly improved, thereby the protection quality also improves a lot.In greening management guidance station " research of Shanghai ginkgo, the fragrant camphor tree rejuvenation of ancient tree key technology " subject study of Shanghai City, it is better that seminar's man analysis draws antiseptic property, the bactericidal effect of charcoal, its splash rise approaching with shrinkage and timber, glass fibre the rising property of splashing is very little, thereby, adopt charcoal, glass fibre to make the packing material of treehole.But the charcoal high adsorption capacity has very strong hygroscopicity, and still has the space in the treehole after filling, and can continue in the treehole to rot, and is subject to the disease worm and infects.
Although hard polyurethane foam has waterproof, anticorrosion, resistance to compression, be difficult for collapsing, the life-span is long, and moulding process is simple, with timber stronger characteristics such as adhesive strength is arranged, and does not find hard polyurethane foam is used for the report of rejuvenation and the maintenance of ancient and well-known trees so far.
[summary of the invention]
The invention provides a kind of new purposes of hard polyurethane foam, just be used for the treehole packing material of ancient and well-known trees rejuvenation and maintenance.
Described hard polyurethane foam is obtained by following method: two kinds of liquid of hard polyurethane foam blowing agent isocyanates and polyethers foam under 15～25 ℃ of conditions after mixing stirring in 1: 0.5～1.5 ratio.
The application of described hard polyurethane foam in ancient and well-known trees rejuvenation and maintenance realized by following steps: connect into indefinite shape with reinforcing bar and wire netting, put in the treehole, support in doing.After blowing agent isocyanates and two kinds of liquid of polyethers were mixed stirring in 1: 0.5～1.5 ratio, the above-mentioned mixed liquor that every cubic metre of usefulness is 70～300 kilograms was poured in the treehole, and the outside is with the fixing sealing of prefabricated mould.
Wherein used isocyanates and polyethers are two kinds of primary raw materials of the hard polyurethane foam sold on the market.
The invention has the advantages that: waterproof, anticorrosion, resistance to compression, the wind resistance folding, fire-retardant, life-span is long, and actuating property and trees itself are approaching, flexible, can combine closely with trunk, it is rotten or impaired to prevent to set the body continuation effectively, does not influence the tree bulk-growth, and attractive in appearance, moulding process is fairly simple.
