Abstract
The invention provides a raw material composition for preparing a heavy caliber polypropylene double-wall corrugated pipe, which consists of 100 mass parts of polypropylene resin, 5 to 50 mass parts of inorganic filling, and 5 to 20 mass parts of interface improver. The inorganic filling is selected from one of carbon black, montmorillonite, calcium carbonate, calcium sulfate, magnesium sulfate, silicon dioxide and titanium dioxide. The interface improver is selected from one or two of silane coupling agent, titanate coupling agent and maleic anhydride grafted polypropylene. The polypropylene raw material in the composition for preparing the heavy caliber double-wall corrugated pipe has higher melt strength and rigidity. The corrugated pipe manufactured by the polypropylene raw material composition achieves even exceeds the HDPE heavy caliber double-wall corrugated pipe which is generally used in the market through detection, and has the advantages of higher ring stiffness, light pipe weight, product cost reduction and the like.
Description
Technical field
The invention belongs to town and country draining pipeline preparing technical field, be specifically related to the material combination composition formula that macromolecular material is made.
Background technology
In recent years, the quick urbanization of China makes the continuous expansion of urban construction scale and the improvement that water pollutes accelerated, water exhaust system is as the important foundation facility in city, effect to the normal operation that ensures the city and urban safety is also obvious day by day, the demand growth of municipal drainage facility is very fast, and reasonably drainage pipe also becomes the important component part of water exhaust system.Along with the exploitation of novel material with apply, increasing sewerage system has been used polyvinyl chloride (PVC), high density polyethylene(HDPE) new type plastic pipes such as (HDPE).Plastic film capicitor is other conventional pipelines such as substituted metal, cement progressively at home, develop very rapidly, and its application quantity every year is with the speed increment more than 50%, good market prospects.
Present raw materials used PVC and the HDPE of mainly concentrating on of domestic market large-caliber double-wall bellow.Along with the raising of environmental protection consciousness, PVC withdraws from the market gradually.Compare with PE, PP has higher modulus of elasticity and lower density, has good cost performance on large-caliber double-wall bellow.Only there are several drainings such as HB242P, the blowdown special material for tube trade mark of 202B, the 212B in external Northern Europe and Korea S star dawn selective in the market.Domestic only have CNPC to raise the sub-petrochemical industry stock company patent (patent No.: ZL200410065143.7) disclose large bore dual-wall polyproplyene corrugated pipe composition, form through the chemical/physical modification by acrylic resin and nucleator and auxiliary agent, the heavy caliber polypropylene corrugated tube PP Pipe Compound of making has higher melt strength, good rigidity and thermotolerance.
As everyone knows, the acrylic resin raw material sources, if can be saved polyacrylic consumption and just equal to have saved the energy when being processed into heavy caliber corrugated tube goods in oil, also can reduce cost concerning enterprise simultaneously with the reply intense market competition.Strengthen resin modified research Showed Very Brisk in Inorganic Fillers Filled both at home and abroad, a good approach is provided.But dosing the mineral filler modification at present in acrylic resin prepares heavy caliber polypropylene corrugated pipe composition and does not see report as yet.Therefore, our employing is dosed the mineral filler modification and is prepared satisfactory heavy caliber polypropylene corrugated pipe composition in acrylic resin, by modulus in flexure that improves polypropylene corrugated tube PP Pipe Compound and then the ring stiffness that improves corrugated tube, reduces product cost.Compare with similar products at home and abroad by the product of present method preparation and to have good cost performance.
Summary of the invention
The object of the present invention is to provide a kind of heavy caliber corrugated tube that improves its modulus in flexure and then improve the ring stiffness grade of corrugated tube.Described large bore dual-wall polyproplyene corrugated pipe is meant the corrugated tube of nominal diameter greater than 400mm.
The quality proportioning of feedstock composition of the present invention is:
100 parts of acrylic resins
5～50 parts of mineral fillers
5～20 parts of interface activators
Wherein: described mineral filler is selected from a kind of in carbon black, polynite, lime carbonate, calcium sulfate, sal epsom, silicon-dioxide, the titanium dioxide; The interface activator is selected from 1～2 kind in silane coupling agent, titanate coupling agent, the polypropylene grafted maleic anhydride.The large-caliber double-wall bellow polypropylene modification raw material of present composition preparation has higher melt strength and rigidity, has both favorable shock resistance, resistance toheat and processing characteristics simultaneously.The mechanical property of this PP Pipe Compound is compared with the virgin pp resin, and its flexural strength and modulus in flexure are greatly improved, and processing characteristics is good.Corrugated tube with pp material composition of the present invention processing meets or exceeds the HDPE large-caliber double-wall bellow that generally uses on the market after testing, has higher ring stiffness, and tubing is in light weight and reduce advantage such as product cost.Large-caliber double-wall bellow with the preparation of polypropylene modification material can be used as buried drain pipe and blow-off pipe, in plastic conduit market good prospects for application is arranged.
