Description

A kind of polyurethane foam material for northern tree insulation
Technical field
The present invention relates to a kind of plastic foam material, particularly relate to a kind of polyurethane foam material for northern tree insulation.
Background technology
The common method be incubated trees is wound form and packaging type.Wound form is the winding rope made of hemp of multilayer on trunk, is incubated trees; Packaging type is that trees periphery support is built certain height, then around trees, uses plastic wraps, reaches the object of trees being carried out to Windproof thermal insulation.
Two kinds of above-mentioned tree insulation method complex operations again unsightly, need a lot of human and material resources, and the time for a long time just can rot to damage, certain pollution is caused to environment, therefore, produce a kind of with low cost, good looking appearance and the good lagging material of performance are necessary
Research and develop the focus that a kind of tree insulation material with low cost, simple to operate, specious, free from environmental pollution is still people's research at present.
Publication number is that the patent of invention of CN101548633A relates to a kind of colorful tree insulation overcoat reused, there is cone lagging material colored outer, cone lagging material primary colors internal layer, the colored outer and middle middle layer having the uniform heat-insulation foam material of thickness to make of primary colors internal layer.It is characterized in that the external diameter up and down of cone should be greater than the external diameter up and down of insulation trunk, the effect that trunk is cold-proof, antifreeze, be incubated is covered to reach overcoat, the overlap being greater than trunk goes out to be provided with easy stickup, and the length of easily pasting and width are determined according to the height of thermal-insulation coat and width demand.Although this kind of insulation construction can reach the object be incubated trees, its complex process, easily damages, and needs a lot of manpower and materials, and well can not reach its said object that can reuse.
Summary of the invention
The object of the present invention is to provide a kind of polyurethane foam material for northern tree insulation, this material is hard polyurethane foam, with isocyanic ester and polyethers for main raw material, under the effect of the multiple auxiliary agents such as whipping agent, catalyzer, fire retardant, mixed by equipment, through high pressure painting, its thermal conductivity is low, is the extraordinary synthetic materials of a kind of heat insulation function.
The object of the invention is to be achieved through the following technical solutions:
For a polyurethane foam material for northern tree insulation, described urethane is formed by organic diisocyanate or polyisocyanates and dihydroxyl or polyol addition polymerization; Its one-tenth is grouped into by weight: polyester 100 parts, fire retardant 10-20 part, catalyzer 2-5 part, stablizer 6-8 part, whipping agent 2-5 part, and the polymeric MDI of the whipping agent 141B and 76% of above-mentioned whole ingredient weight 19%; Prepare burden by formula to after products material inspection, then add whipping agent, fire retardant, stablizer, catalyzer stirring 1-2 hour, carry out foam process, and slaking, make polyurethane foam material.
Described a kind of polyurethane foam material for northern tree insulation, described foam material material temperature controls at 20-35 DEG C, envrionment temperature more than 20 DEG C.
Described a kind of polyurethane foam material for northern tree insulation, the phase is warming up to 170-190 DEG C to described foam material after curing, melts stand-by by its foam.
Advantage of the present invention and effect are:
1. the present invention is that a kind of colour of surviving the winter for northern trees can spray coating foaming lagging material, it can solve that existing many tree insulation methods, material cost are expensive, contaminate environment, the difficult problem such as unsightly, under the prerequisite improving these problems, can well reach the object of insulation trees.
2. urethane full name is polyurethane(s), is containing the general designation of macromolecular cpd repeating carbamate groups on main chain, and it is formed by organic diisocyanate or polyisocyanates and dihydroxyl or polyol addition polymerization.
3. the mechanical property of urethane has very large adjustability.By the ratio between the hard section of crystallization control and non crystallized soft section, urethane can obtain different mechanical properties.Therefore its goods have the excellent properties such as wear-resisting, heatproof, sealing, sound insulation, good processability, degradable.
4. what lagging material adopted is hard polyurethane foam, hard polyurethane foam is for main raw material with isocyanic ester and polyethers, under the effect of the multiple auxiliary agents such as whipping agent, catalyzer, fire retardant, mixed by specific equipment, through the high molecular polymer of high pressure painting foam-in-place.Polyurethane foam has soft bubble and hard bubbles two kinds.Soft bubble is open-celled structure, hard bubbles as unicellular structure.
5. hard polyurethane foam is the extraordinary novel synthetic material of a kind of heat insulation function, and its thermal conductivity is low, only 0.022 ~ 0.033W/(m* Κ), being equivalent to the half of extruded sheet, is that in current all lagging materials, thermal conductivity is minimum.Rigid urethane foam is mainly used in skin insulation, waterproofing and thermal insulation of roofing integration, heat preservation of refrigeration storage heat insulation, pipe insulation material, building board, refrigerator car and the heat insulation material of freezer etc.
