Description
Technical field
The present invention relates to a kind of swelling foam material and preparation method thereof, the swelling foam material that particularly a kind of shock-absorbing capacity is good, have certain intensity.
Background technology
In the current road and public utility construction, the pipe for supporting such as support bar for lamp stand, road sign display board use iron and steel or wood materials more.The hardness of these materials is higher, if traffic accident, the human impact because impact force is bigger, very easy to be injured, endangered personnel safety, so result of use is bad on lamp stand or support bar the time.
Summary of the invention
The objective of the invention is to, a kind of swelling foam material and preparation method thereof is provided.Its shock-absorbing capacity is good, in the time of can alleviating traffic accident, and the injury that the human impact is subjected to.
Technical scheme of the present invention.Swelling foam material, component is calculated by weight, and it is made for 100～250 parts by 20～65 parts of polyether glycols, 20～30 parts of polyester polyols, 1～4 part in water, 5～20 parts of Skellysolve As, 1～2 part of Primary Catalysts, 1～2 part of promotor, 1～2 part of silicon foam stablizer, thick isocyanic ester.
Above-mentioned swelling foam material, it is made for 150～200 parts by 40～50 parts of polyether glycols, 23～27 parts of polyester polyols, 1～2 part in water, 8～14 parts of Skellysolve As, 1～2 part of Primary Catalysts, 1～2 part of promotor, 1～2 part of silicon foam stablizer, thick isocyanic ester.
Aforesaid swelling foam material, catalyzer adopts tertiary amine compounds, and promotor adopts organo-tin compound.
Aforesaid swelling foam material, Primary Catalysts adopts N-aminoethyl ethanolamine, and promotor adopts stannous octoate.
The making method of aforementioned swelling foam material is mixed polyether glycol, polyester polyol, water, Skellysolve A, Primary Catalysts, promotor, silicon foam stablizer and thick isocyanic ester, stirs, and pours in the mould with low pressure foaming PU bottler.
The making method of above-mentioned swelling foam material goes out strut member (1) with steel pipe manufacturing earlier, produces protective layer (3) by mold injection with resin again, puts protective layer (3) outside strut member (1), and the space is left in the centre; Above-mentioned materials is mixed, stir, pour in the space of strut member (1) and protective layer (3) as foam-filled layer (2).
The swelling foam material that the present invention adopts can cover the surface of lamp stand and other support bars, low, the light weight of expanding layer density, has certain mechanical strength, shock-absorbing capacity is good, when bump takes place, can absorb impact force rapidly, reduce the injury that human body is subjected to, even the stressed excessive damage of expanding layer is fallen, reuse after also can reclaiming.Energy moistureproof and mildewproof, water resistance meet international environmental requirement.
Polyurethane(s) is a kind of organic polymer material, be to contain in the molecular structure-the unitary macromolecular compound of NHCOO-, its wear resisting property is good, under same rigidity, than the elastomerics supporting capacity height of other foam materials, the shock resistance height, the resilience scope is wide, therefore, it can be used as a kind of material of good supporting load larrying member.Owing in the middle of the packing layer material many gaps are arranged, therefore, when being subjected to external impacts, slight deformation takes place between each site, can cushion most power.Simultaneously, this material has certain memory, finds that soft chain segment has formed the crystallizing field that stress caused under the fiber extended configuration in the diffraction experiment of X-ray, because the enhancing of structure causes rigidity and the intensity of fiber under extended configuration all to increase.When external force is removed, bounce back at once, the crystallization of soft chain segment disappears, and molecule returns rolled state again just can recover original outward appearance in the short period of time.
Is polyurethane(s) 140? stable down, not influenced by the ozone erosive, radiation hardness, antifungal, low friction.The strength ratio natural timber height of polyurethane(s) because middle gapped, so density than natural timber low (300～700kg/m3), reliable assurance has been arranged on the intensity, make him lighter again simultaneously than similar quality of materials, transportation with install more convenient.Since can with timber, metal and most of plastic bonding, adhesive ability is very strong, therefore, can be combined as a whole with the metal tube of inside, when the outside when body applies reactive force, as the packing layer of load larrying member can be used as again to inside and outside two-part carry out strong fastening.But also having molding and tooling cost is low, oil resistant, fat and chemical are difficult for advantages such as contaminations, because polyurethane(s) plasticity-is more intense, manually and the material cost very economical, reuse after can also reclaiming.Therefore the present invention can be widely used in fields such as lamp stand packing layer, construction wall thermal insulation layer, tubing thermal insulation layer.
