Abstract
The invention discloses a pipe for building and the manufacturing method, comprising a protective layer (1) at the outside and filling layer (2) in the protective layer (1). The invention adopts special two-layer structure. It is combined with the protective layer together by the middle foam filling agent. It is provided with stable property, strong application for zone and climate, convenience installment, saving return material, more environmental protection, beautiful-looking and safety so on. It can be used as the barrier of gardens and roads or lawn lamp post and so on. The combination structure of polyurethane and outer resin can take the effect of buffering to protect human safety. At the same time certain material proportion is used to set breaking coefficient so as to avoid overlarge damage of impacting object or human according to the value of impacting force.
Description
Technical field:
The present invention relates to a kind of building pipe and preparation method thereof, particularly a kind of building pipe that is used for public facilitieies such as guardrail, lawn light.
Background technique:
In the current road and public utility construction, for building pipes such as lawn light, flowering shrubs guardrail, road guards, iron and steel or the wood materials of using more, in the utilization of reality, use the cost of ferrous materials higher, for the difficulty height of moulding aspect, make in appearance relatively dullness to lack flexibility and diversity on the surface-treated process aspect; For the external facilities of iron and steel material quality, accomplish anticorrosionly must carry out processing such as overlay coating or plastic-blasting, produce many environmental pollution problems accordingly; And iron and steel hardness height, the human impact is injured easily in the above during traffic accident.On the other hand, if use wood materials then the problem that manifests is more, at first, be difficult to accomplish fracture and distortion easily during bump aspect the hardness as the facility of wood materials; Secondly,, be subjected to the influence of factors such as ambient temperature, weather condition as external facilities, timber degrade and situation such as corruption serious; Also have fireproof performance poor, easily being stained with ash or the like all is the shortcoming of wood materials.
Summary of the invention
The objective of the invention is to: provide a kind of stable in properties, region and climate adaptability strong, easy for installation, and reuse, environmental protection more, building pipe attractive in appearance and preparation method thereof.
Technological scheme of the present invention.A kind of building pipe, it is made up of the packed layer (2) that is in outer field protective coating (1) and is positioned at protective coating (1).
Above-mentioned building pipe is that packed layer (2) adopts polyurethane.
Aforesaid building pipe is that protective coating (1) adopts polyethylene.
Aforesaid building pipe is that protective coating (1) adopts medium density polyethylene or high density polyethylene (HDPE).
Aforesaid building pipe is that adding in the polyethylene of protective coating (1) has photomask agent, fire retardant and age resister.
The making method of aforementioned building pipe, it is to produce protective coating (1) earlier, is poured into packed layer (2) again in protective coating (1), the processing of foaming waits packed layer (2) to solidify and obtains tubing.
The present invention relates to a kind of building pipe, its outside material that protective coating adopted is the polyethylene resin material, polyethylene is a kind of degree of crystallinity height, nonpolar thermoplastic resin, odorless, nontoxic, the feel ceraceous, has good resistance to low temperature (minimum serviceability temperature can reach-70～-100 ℃), chemical stability is good, and the erosion of acid resistant alkali is insoluble to common solvent under the normal temperature, moisture absorption is little, electrical insulation capability is good, and reusable edible is simultaneously by adding photomask agent in polyethylene, fire retardant and age resister, former polyethylene is carried out modification, make the polyethylene after the modification also have antiultraviolet, slow down aging and fire-retardant function, arrive the standard of UL94.The packed layer of pouring is a polyurethane in its protective coating, polyurethane is a kind of high-molecular organic material, be to contain in the structure of molecule-polymeric compound of NHCOO-unit, it is good that it has a wear-resisting property, under same rigidity, and other foamed material relatively, has elastomer bearing capacity height, the impact resistance height, advantage such as the resilience scope is wide can be used as a kind of material of good supporting bearing structure.In the middle of the packed layer material after the foaming many gaps are arranged simultaneously, when being subjected to external impacts, slight deformation takes place between each site, can slow down impact force.Simultaneously detect this material and also have certain Memorability, but in the short time behind the compressive deformation, recover original outward appearance according to the expert.And is polyurethane 140? stable down, the influence that not corroded by ozone has the performance of radiation hardness, antifungi and low friction.The strength ratio natural timber height of polyurethane, its internal void makes it lighter than similar quality of materials again, has guaranteed transportation and the convenience of installing.Simultaneously polyurethane can with timber, metal and most of plastic bonding, adhesive ability is very strong, can be combined as a whole with the protective coating of outside.
With above-mentioned two kinds of building pipes that material is made, the protective coating on surface is more convenient on treatment process, and reduce surperficial plastic-blasting and be coated with technology, more environmental protection, and also by the mold injection typing, the cost aspect plastotype is more cheap, and efficient is higher.Than common steel pipe tubing, building pipe of the present invention not only material is light, convenient transportation, be easy to installation and removal, and, good assurance arranged all on the fireproof performance at fastness, and can not get rusty, even the tubing appearance damages, protective coating and packed layer can also be reclaimed pulverizing plastotype use once more later on, in the resource circulation utilization, have very strong advantage.The present invention simultaneously adopts special two-layer structure, it is strong, easy for installation that such building pipe has stable in properties, region and a climate adaptability, save reclaiming material, environmental protection more, advantage such as attractive in appearance, safe can be used for the fence gardens, road used or making lawn lamppost etc.The combined structure of polyurethane and outermost resin also plays buffer function on the other hand, and the effect of protection personal safety can be used certain material mixture ratio simultaneously, by the size of impact force, sets the coefficient that fractures, and makes rammer or people avoid macrolesion.

Embodiment
Embodiments of the invention: building pipe, as shown in Figure 1, earlier go out protective coating 1 by Mold Making according to desired height and profile, protective coating 1 can use medium density polyethylene or high density polyethylene (HDPE), also can in the polyethylene of protective coating 1, add photomask agent is arranged, fire retardant and age resister, add in the polyethylene photomask agent is arranged, fire retardant and age resister, photomask agent can be selected titanium white or carbon black for use, make the polyethylene antiultraviolet, longer service life is of a specified duration out of doors, fire retardant is selected phosphor nitrogen combustion inhibitor for use, makes polyethylene have fire-retardant function, uses safer.Age resister can be selected antioxidant such as phenols, arylamine class etc. for use, and such as antioxidant 264, antioxidant 1010, dilauryl thiodipropionate or triphenyl phosphite etc., age resister can make polyethylene to heat, and oxygen deflects, and fatigue aging has good protective benefits.Can make by existing mold injection technology when making protective coating 1.Inject packed layer 2 again in the protective coating of making 1, packed layer 2 adopts polyurethane, to the polyurethane processing of foaming, can obtain ornamental tubing after waiting polyurethane to solidify.
