Abstract
The invention belongs to the field of corrosion resistance and heat insulation of ground pipelines, in particular to a ground copolymer foam corrosion-resistant heat insulation pipe. The pipe comprises a pipe body (1); a heat insulation layer (2), a protective layer and a corrosion-resistant layer (5) are fixedly arranged on an outer wall of the pipe body (1); the protective layer is positioned between the heat insulation layer (2) and the corrosion-resistant layer (5); the heat insulation layer is made of rigid polyurethane foam; the protective layer comprises a polymer cement mortar elastomer layer (4) and an environmentally-friendly non-woven fabric layer (3); and the polymer cement mortar elastomer layer (4) is prepared by mixing and stirring a polyester adhesive, cement, mortar and a chloroethylene mixing agent. The pipe has the advantages of high mechanical strength, high ageing resistance, good waterproof performance and long service life.
Description
Technical field
The invention belongs to surface duct corrosion-resistant thermal insulation field, relate in particular to a kind of ground copolymer foam anti-corrosion heat insulation pipe.
Background technique
The most of area of northern China, pipelines such as crude oil, heating are adopted the ground mode to lay and when standing pipeline network construction, are all needed to take anticorrosion and the insulation measure.General ground anti-corrosion heat insulation pipe anticorrosive coat adopts coating to brush, and thermal insulation layer adopts rock wool or fibre pipe shell products such as silicate, alumina silicate, also needs galvanized wire to carry out colligation, and protective layer adopts galvanized sheet iron and reinforces with rivet.Above-mentioned processing mode compressive strength is low, and is anti-aging and water-proof performance is poor, and product comprehensive quality can not get ensureing.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and a kind of mechanical strength height is provided, and is anti-aging and water-proof performance good, the ground copolymer foam anti-corrosion heat insulation pipe of long service life.
For achieving the above object, the present invention is achieved in that
Ground copolymer foam anti-corrosion heat insulation pipe, it comprises body; Be fixed with thermal insulation layer, protective coating and anticorrosive coat at described tube wall; Described protective coating is between thermal insulation layer and anticorrosive coat; Described thermal insulation layer adopts hard polyurethane foams; Described protective coating comprises polymer cement mortar elastomer layer and environmental protection type nonwoven layer of cloth.
As a kind of preferred version, polymer cement mortar elastomer layer of the present invention is mixed together by polyester adhesive, cement, mortar and the agent of vinyl chloride mix.
The present invention can improve the comprehensive quality of products such as the compressive strength, ageing resistance of surface duct corrosion-resistant thermal insulation comprehensively, its protective coating has excellent mechanical intensity, stress cracking performance of anti-environmental aging the and distinctive plastic elongation, and have excellent waterproof, compressive strength, anti-ultraviolet property, can forever use in the sun.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention;
Among the figure: 1 is body; 2 is thermal insulation layer; 3 is the environmental protection type nonwoven layer of cloth; 4 is the polymer cement mortar elastomer layer; 5 is anticorrosive coat.
Embodiment
Referring to shown in Figure 1, ground copolymer foam anti-corrosion heat insulation pipe, it comprises body 1; Be fixed with thermal insulation layer 2, protective coating and anticorrosive coat 5 at described body 1 outer wall; Described protective coating is between thermal insulation layer 2 and anticorrosive coat 5; Described thermal insulation layer adopts hard polyurethane foams; Described protective coating comprises polymer cement mortar elastomer layer 4 and environmental protection type nonwoven layer of cloth 3.Polymer cement mortar elastomer layer 4 of the present invention is mixed together by polyester adhesive, cement, mortar and the agent of vinyl chloride mix.
Ground of the present invention copolymer foam anti-corrosion heat insulation pipe is divided into thermal insulation layer, protective coating and three kinds of structures of anticorrosive coat.
Ground anti-corrosion heat insulation pipe thermal insulation layer is the enhancement type hard polyurethane foam, this foam density is low, intensity is high, thermal conductivity is extremely low, can adopt admixtured polyether prescription and the agent of PU-88 powder foam, the mixed proportion of polyisocyanates and polyether polyol is 1: 1, and the agent of PU-88 powder foam accounts for 10%～12% of admixtured polyether gross mass.
Protective coating has adopted polymer and non-woven fabric compounded technology, is made of environmental protection type nonwoven cloth and polymer cement mortar elastomer, and polymer elastomer is mixed together by polyester adhesive, cement, mortar and the agent of vinyl chloride mix.After copolymer elastomer was smeared and finished, the protective coating air dry just can be used in 24 hours.
This protective coating has excellent mechanical intensity, and stress cracking performance of anti-environmental aging the and distinctive plastic elongation have excellent waterproof, compressive strength, anti-ultraviolet property, can forever use in the sun.
Anticorrosive coat is formed by the applying coating that satisfies anticorrosive coat performance, thickness and colour planning requirement, has corrosion protection and effects such as caution, difference.
Ground of the present invention copolymer foam anti-corrosion heat insulation pipe steady quality, thermal insulation layer intensity height, thermal conductivity is low, heat-insulating property is good, and nonwovens environmental protection, antiseptic property are good, and the polymer cement mortar protective coating can the scene directly adds water and stirs and can smear, the bond strength height, with foam good compatibility is arranged, and have excellent cracking resistance, barrier performance, weather resistance is good.
Ground of the present invention copolymer foam anti-corrosion heat insulation pipe is safe and reliable, can satisfy the HSE requirement, adapts to ∮ 89～∮ 1220mm caliber.
Be with being appreciated that, more than about specific descriptions of the present invention, only be used to the present invention is described and be not to be subject to the described technological scheme of the embodiment of the invention, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the present invention, to reach identical technique effect; Use needs as long as satisfy, all within protection scope of the present invention.
Claims (2)
