Description

The soft sheath of complex heat-preservation

Technical field

The soft sheath of complex heat-preservation belongs to hot and cold pipeline, water heating system, other tube for fluid transfer material field of thermal insulation.

Background technique

At present, both at home and abroad air-conditioning system, water heating system, other fluid delivery systems generally adopt metal pipe outside suit or coat thermal insulating material, or adopt conventional plastics and generally expandable plastic be coated in the metal tube outer surface and be incubated.The thermal insulation pipe of suit is the individual layer expandable plastic, because the expansion ratio height, rate of closed hole is low, the easy and environment formation convection current of heat, so moisture retention is poor.The thermal insulation pipe appearance does not increase the design of thermodynamic property yet.Heat insulation effect is poor, energy consumption is big.Through " Chinese patent " retrieval, still there is not the soft sheath of the complex heat-preservation that once is made into type.

Technology contents

The technical problems to be solved in the utility model is, a kind of high insulating effect is provided, improves more than 10 times than general thermal insulating material, and intensity height, low, corrosion-resistant, the economical with materials of cost can the soft sheaths of one-time formed complex heat-preservation, filled up a blank in this field.

The technological scheme that its technical problem that solves the utility model adopts is, the soft sheath of this complex heat-preservation, comprise two-layer thermal insulation layer, interior foaming layer 3, middle foaming layer 2, outside the foaming layer 3, be compounded with reflective thermal-insulating layers 1 outside the middle foaming layer 2 in middle foaming layer 2 is compounded in, interior foaming layer 3, middle foaming layer 2, reflective thermal-insulating layer 1 are fixed as a whole, can be processed into random lengths continuously, and adopt the soft sheath of insulation of an extrusion molding compound molding of forming equipment.

The soft sheath of complex heat-preservation of the present utility model, compared with prior art the beneficial effect that is had is: owing to adopt double-layer foamed layer compound, outer expansion ratio is lower than internal layer foaming foaming layer multiplying power, the rate of closed hole height, outermost surface adopts nanometer infrared rays reinforcing reflex layer, high insulating effect, improve more than 10 times than general thermal insulating material, can cut down the consumption of energy greatly, simultaneously outer nanometer infrared rays reinforcing reflex layer design is stereochemical structure, the intensity height, but corrosion-resistant, improve advantage such as efficiency of construction one piece extrusion molding compound molding.Can be widely used in the insulation of each field tubing such as air-conditioning system, water heating system, other fluid delivery systems, have vast market prospect.

Below in conjunction with accompanying drawing 1-6 the soft sheath of complex heat-preservation of the present utility model is described in further details: among Fig. 1: the foaming layer 4 three-dimensional trapezoidal 5 three-dimensional ripples that go in ring in the foaming layer 3 in the 1 nanometer infrared rays reinforcing reflex thermal insulation layer 2.

Embodiment

As shown in Figure 1: be the overall structure that nanometer infrared rays reinforcing reflex thermal insulation layer 1, middle foaming layer 2, interior foaming layer 3 are combined with each other, the high-multiplying power foaming is taked in interior foaming layer 3, can hold more air like this, because the heat conductivity of air is very low, differing an order of magnitude with general macromolecular material, is good thermal insulation medium therefore.In foaming layer 2 take the lower slightly expansion ratio of interior foaming layer 3, and adopt different process conditions, obtain more closed pore alveolitoid structure.Because the closed cell structure, the air between the alveolitoid does not connect and convection current.Therefore stoped because the energy that inner air and environmental gas convection current produce scatters and disappears.Further having increased thermal insulation property and infrared reflection effect nanometer improves.The soft sheath of this complex heat-preservation has unique three-decker, because three-decker has adopted different materials and different expansion ratios.Therefore the effect of having nothing in common with each other because the collaborative heat conductivity of this tubing that makes of three layers of characteristic reduces greatly, has improved insulation effect.

Middle foaming layer 2 outer reflective thermal-insulating layers 1 employing of the soft sheath of complex heat-preservation have barrier to air and ultraviolet ray are had the macromolecular material of shielding action.The convection current of further prevention heat is arranged and prevent the aging damage that the daylight middle-ultraviolet lamp causes tubing.Because reflective thermal-insulating layer 1 material has the far-infrared reflection effect.The energy that radiation produces can be reflected again.Thereby strengthen insulation effect once more.For the mechanical property reflective thermal-insulating layer 1 that increases the soft sheath of complex heat-preservation has designed three-dimensional circular ripple or three-dimensional trapezoidal.This product with compared with prior art have the following advantages:

1, owing to the three-decker characteristic different with each layer, the monolayer heat-insulating pipe thermal insulation property more common than existing market improves several times.The soft sheath of this complex heat-preservation is owing to adopted automatic continuous three layers of composite co-extruding production technology.Product can be made random lengths continuously and can reach more than the hundreds of rice.Can arbitrarily intercept during use.The at present common thermal insulation pipe that has foam sheet to make can only be accomplished 1-2 rice.

2, can be as required three layers make variant color in order to distinguish different purposes or special identifier.

3, the soft sheath skin of complex heat-preservation has the ripple or the decorative pattern of three-dimensional ring curl or body ring rhombus or other stero shapes, can increase the mechanical property of heat-insulated pipe.

Fig. 3 is the soft sheath of complex heat-preservation, according to different use occasions, with the conjuncted structure that is produced on together of the soft sheath of complex heat-preservation of two different sizes.Can satisfy the demand of multiple service condition.Also can be with conjuncted being produced on together of the soft sheath of complex heat-preservation of identical or different specification more than two.

Fig. 2, the 5th, the soft sheath reflective thermal-insulating of complex heat-preservation layer is designed to the profile and the sectional shape of three-dimensional ring ripple, can increase the mechanical property of heat-insulated pipe.

Fig. 1, the 4th, the cross section and the outer shape of the outer three-dimensional trapezoid shaped of the soft sheath of complex heat-preservation can increase the mechanical property of heat-insulated pipe.Also can design the ripple or the decorative pattern that are other stero shapes.
