Abstract
A flame-retardant polypropylene composite pipe belongs to the technical field of pipes, is a three-layered composite pipe, and comprises a flame-retardant outer layer, a composite material interlayer and a polypropylene inner layer which are formed through one-step extrusion molding by adopting the co-extrusion technology and sequentially arranged from outside to inside in a matched manner. By adopting the technology, the inner pipe enables the polypropylene pipeline to have favorable sanitation and good surface smoothness; the outer layer made from a flame-retardant polypropylene composite material endows the pipe with a flame-retardant effect, and the ignition or burning time of the whole pipe is delayed; the intermediate layer is a glass fiber and polypropylene resin composite material interlayer, so that both the tensile strength and the bending strength of the pipe are improved by 10 percent, and the linear expansion coefficient is reduced to one third of that of common polypropylene; and the flame-retardant polypropylene composite pipe is particularly suitable for occasions demanding much on fire control and fire protection.
Description
Technical field
The utility model belongs to the tubing technical field, is specifically related to a kind of have good flame retardation effect, comprehensive mechanical property is good and coefficient of linear expansion is little flame-retardant polypropelene composite pipe.
Background technique
Structural material and goods combustibility are very important to life safety and the property safety that guarantees people in the building, and is all the more so on boats and ships, and the fire that the burning of material and goods causes tends to cause great casualties and property loss.In recent years PPR tubing has obtained development rapidly in feedwater fields such as building, boats and ships, replaces traditional PVC, metallic conduit gradually.Its advantage be environmental protection quick and easy for installation, economic and practical, in light weight, health is nontoxic, good heat resistance, corrosion-resistant, good heat insulating, life-span are long etc., but the not anti-combustion of PPR tubing has the occasion of fire-fighting requirement and fire protection requirement to use at some.
The model utility content
At the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of good flame retardation effect, comprehensive mechanical property is good and coefficient of linear expansion is little flame-retardant polypropelene composite pipe.
Described a kind of flame-retardant polypropelene composite pipe, it is characterized in that described tubing is the three-decker composite pipe, comprise the fire-retardant skin, composite material interlayer and the inner layer of polypropylene that are equipped with successively from outside to inside, the skin of described fire-retardant skin for making by PP composite material by an extruding and moulding of co-extrusion technology.
Described a kind of flame-retardant polypropelene composite pipe, it is characterized in that described composite material interlayer for by glass fibre and polyacrylic resin material blend obtain composite layer.
Described a kind of flame-retardant polypropelene composite pipe is characterized in that with the total wall thickness gauge of tubing, described fire-retardant outer field thickness accounts for the 40-45% of total thickness.
Described a kind of flame-retardant polypropelene composite pipe is characterized in that with the total wall thickness gauge of tubing, the thickness of described composite material interlayer accounts for the 25-30% of total thickness.
Described a kind of flame-retardant polypropelene composite pipe is characterized in that the thickness of described inner layer of polypropylene accounts for 30% of total thickness with the total wall thickness gauge of tubing.
Above-mentioned a kind of flame-retardant polypropelene composite pipe is the three-decker composite pipe, comprises the fire-retardant skin, composite material interlayer and the inner layer of polypropylene that are equipped with successively from outside to inside by an extruding and moulding of co-extrusion technology.The utility model is by adopting above-mentioned technology, in guarantee and held the good good surface finishment of wholesomeness of polypropylene pipe, outerly make tubing have flame retardant effect by flame-retardant polypropylene composite material, delayed the time that whole tubing catches fire or burns.The glass fibre in mesosphere and the composite material interlayer of acrylic resin, make the tensile strength and the flexural strength of tubing improve 10%, linear expansion coefficient is reduced to below 1/3rd of plain polypropylene, and the occasion that is particularly suitable for fire-fighting requirement and fire protection requirement is used.
Description of drawings
Fig. 1 partly cuts open schematic representation for the utility model master looks;
Fig. 2 cuts open figure for A-A face among Fig. 1.
Among the figure: the fire-retardant skin of 1-, 2-composite material interlayer, 3-inner layer of polypropylene.
Embodiment
The utility model will be further described below in conjunction with Figure of description:
Shown in Fig. 1-2, a kind of flame-retardant polypropelene composite pipe, be the three-decker composite pipe, comprise fire-retardant outer 1, composite material interlayer 2 that is equipped with successively from outside to inside and inner layer of polypropylene 3 by an extruding and moulding of co-extrusion technology, with the total wall thickness gauge of tubing, described fire-retardant outer 1 thickness accounts for the 40-45% of total thickness, and the thickness of composite material interlayer 2 accounts for the 25-30% of total thickness, and the thickness of inner layer of polypropylene 3 accounts for 30% of total thickness.Described composite material interlayer 2 for obtain by glass fibre and polyacrylic resin material blend composite layer.
The utility model internal layer polypropylene material, guarantee in making and held the good good surface finishment of wholesomeness of polypropylene pipe, outer fire-retardant skin by making by flame-retardant polypropylene composite material, make tubing have flame retardant effect, delayed the time that whole tubing catches fire or burns, and the composite material interlayer of the glass fibre in mesosphere and acrylic resin, make the tensile strength and the flexural strength of tubing improve 10%, linear expansion coefficient is reduced to below 1/3rd of plain polypropylene, and the occasion that is particularly suitable for fire-fighting requirement and fire protection requirement is used.
