A composite pipe material for building is composed for high-weatherability flame-retarding polypropene layer as external layer, glass fibre reinforced polypropene layer as middle layer and sanitary-class high-glossy polypropene layer as internal layer. Its advantages are high antiageing nature, high photogradation and fire-resistance, high strength and rigidity, low flow resistance and low noise.

Description

A kind of composite pipe material for building
Current era, novel material emerges in an endless stream, and is embodying particularly evidently aspect the chemical building material of building trade.With the pipeline material of chemical building material, it is mainly used in the transmission of various liquid or gas, and its material develops into plastic material of today, matrix material by initial cast iron materials.No matter, still on performance, all being greatly improved from the material application facet, common having be hard-polyvinyl chloride (U-PVC) pipe, crosslinked polyethylene (XPLE) pipe, aluminum-plastic laminated tube.
The U-PVC pipeline material occurs as the substitute of cast iron pipe.This strength of materials height, corrosion-resistant, flame retardant properties good, low price, but it has several fatal weakness: temperature resistant grade is low, and the life-time service temperature is no more than 65 ℃; The frost resistance aspect, the U-PVC pipe can not be at the sub-zero temperature life-time service; The shock resistance aspect, UPVC manages because employing glue is bonding, poor-performing; And polyvinyl chloride is polymerized by vinylchlorid (VCM), and inevitably VCM has residual existence, and VCM is the carcinogenic substance that has been identified, therefore limited the application that PVC becomes the water service pipe material; The U-PVC pipe adds the additive of heavy metal aborning in addition, from environmental angle, causes medium pollution easily.From present domestic situation, the U-PVC pipe generally only limits to the conveying of undrinkable water under the normal temperature.
Aluminum-plastic laminated tube is that employing polyethylene (PE) or crosslinked polyethylene (XPLE) are ectonexine, and intermediate core layer folder one welding aluminum pipe is bonding at aluminum pipe surfaces externally and internally coating glue paste and plastic layer, by the pipeline material of composite co-extruding technological forming.This composite pipe material material mechanical property is good, but it also has weak point, mainly shows: heatproof aspect, life-time service temperature are 85 ℃, if temperature is too high, the difference of the SMIS aluminium lamination and the inside and outside PE layer coefficient of expansion easily causes the interlayer breakaway; Poor fire; From environmental angle, because the centre is the non-degradable aluminium lamination, its rubbish causes environmental pollution easily; From in price, material price costliness, and production unit, the many dependence on import of technology at present, production cost height.
Crosslinked polyethylene (XPLE) adopts cross-linking method, make PE form the space reticulated structure, thereby had good comprehensive physical and mechanical properties, thermal characteristics and wholesomeness, but the XPLE material does not have flame retardant resistance, and environment for use is had certain requirement; And price is more than a times of general polypropylene material.
Purpose of the present invention is exactly to provide a kind of composite pipe material for building in order to overcome the defective that above-mentioned prior art exists, and it has excellent flame-retardant performance, anti-aging, anti-photodegradation, and has the characteristic of high just high-strength, inwall high glossiness.
Purpose of the present invention can realize in the following manner:
A kind of composite pipe material for building is characterized in that: it is composited by trilaminate material, the prescription of every layer material following (weight part, down together):

Described outer field inorganic filler is a superfine talcum powder.
The oxidation inhibitor of described skin and internal layer comprises main anti-Hinered phenols, auxilliary anti-sulfur compound or phosphorous acid esters.
Described thermo-stabilizer comprises barium stearate, cadmium stearate.
Described compatilizer is the oligopolymer of the graft polymerization of polypropylene and unsaturated acid anhydride.
Described coupling agent is silicane or titante coupling agent.
The oxidation inhibitor in described middle layer is Hinered phenols antioxidant.
The weighting material of described internal layer comprises 325~600 purpose talcum powder, mica powder, inorganicss such as the lime carbonate more than 1250 orders, barium sulfate.
Described auxiliary agent is a calcium stearate.
Compared with prior art, the present invention proposes a kind of novel composite building material, this material has taken into full account the environment for use requirement as material of construction, has satisfied simultaneously and has built required mechanical strength requirement, composite inner has adopted the high glossiness anti-biotic material, has satisfied hygienic requirements.This novel composite material is to be that the base-material modification gets low price with the polypropylene.Because polypropylene material density is a kind of of minimum in the plastics, and is therefore in light weight, and can be to the stressed difficulty that causes of upholder.Polyacrylic Applicable temperature can fully satisfy the requirement of hot-water line in the material of construction up to 120 ℃.
The 3-layer composite material that the present invention proposes, skin is the weather-resistance flame-retardant polypropylene layer, and the centre is the glass-reinforced polypropylene layer, and internal layer is a high gloss health grade polypropylene layer.This compound structure is to consider to have the characteristic that integrates numerous advantages from usability and suitability as material of construction.Its cladding material directly contacts with external environment, and material has well anti-aging, anti-photodegradation.Consider the outside atmosphere that material of construction uses, so cladding material also has flame retardant resistance, to reach the fp requirement.The intermediary glass-reinforced polypropylene, the mechanical property of having given the high-strength Gao Gang in middle layer.As the pipeline material material, it is low that the high gloss antibacterial polypropylene of internal layer can show surface tension, prevents fouling, and resistance is little, and flow is big, and noise is little, and the while is breed bacteria not, meets the GB9687-88 hygienic requirements.This matrix material outer, in, interior three layers can adopt composite co-extruding technology because three layers be polypropylene modified material all, consistency is fine, does not need to adopt technologies such as bonding, has simplified the requirement to technology.
