Description
Technical field
The present invention relates to the polyethylene resin composition of polymeric material field, say further, relate to gas line warning panel polyethylene resin composition and manufacture method.
Background technology
20th century the mid-80, the Ministry of Construction, China Petrochemical Corporation and shared country of Shanghai Gas Company " the Seventh Five-Year Plan " brainstorm project, apply plastics coal gas tubing in China, and from then on the application of China's combustion gas tubing is also progressively carried out.Along with the adjustment of national energy structure, the perfect of gas line utilisation technology and people are to the understanding of fuel gas polyethylene tubing superiority, the market potential of polyethylene gas pipe starts to manifest.The Eleventh Five-Year Plan period, pull by the powerful of domestic needs, China's polyethylene gas pipe development is very rapid, is widely used in mesolow gas pipeline.
Polyvinyl fuel gas pipeline is often subject to the shock of hard thing and is punched in construction process, and this is the significant problem of construction quality hidden danger aspect, if do not managed control, often causes hardly imaginable security incident.At community pipe network when supporting or other piping installations of road, the more shallow polyvinyl fuel gas pipeline of the depth of burying is easily pounded to be worn, and causes gas leakage.Therefore require to require to lay warning panel above gas line when laying gas ductwork, protection gas pipeline, improves safety coefficient.Wherein an anti-perforation characteristic of key index proposes according to AS4702-2000, requires that on test specimen, arbitrary test point tup penetration depth after 125J drop impact is no more than 50mm and estimates on test specimen without any cracking or indications of fracture.
At present, do not have special gas line polyethylene warning panel PP Pipe Compound, prepared by the general polyethylene of common model that adopts, be difficult to meet index.
Summary of the invention
In order to solve problems of the prior art, the present invention has invented one and has been used as gas line warning panel polyethylene resin composition.Adopt mixing of high density polyethylene(HDPE), EPDM, carbon black and oxidation inhibitor blended with linear polyethylene, can prepare the gas line warning panel meeting respective standard requirement, comparatively speaking, and cost is controlled, wide material sources.
The invention provides a kind of gas line warning panel polyethylene resin composition, comprising:
In a preferred embodiment of the present invention, described linear low density polyethylene is 0 ~ 40 mass parts.
In a preferred embodiment of the present invention, the consumption of described terpolymer EP rubber is 5 ~ 35 mass parts.
In a preferred embodiment of the present invention, the consumption of described carbon black is 2 ~ 10 mass parts.
In a preferred embodiment of the present invention, the consumption of described oxidation inhibitor is 0.2 ~ 1 mass parts.
In a preferred embodiment of the present invention, described oxidation inhibitor is antioxidant 1010 and/or irgasfos 168.In further preferred implementation, the weight ratio of described antioxidant 1010 and irgasfos 168 is 1:1.5 ~ 2.5.
Present invention also offers a kind of preparation method of gas line warning panel polyethylene resin composition, comprise comprising described linear low density polyethylene, the component of high density polyethylene(HDPE) obtains described polyethylene resin composition by described content melt blending.
Particularly, the method comprises the following steps:
1) linear low density polyethylene, high density polyethylene(HDPE), EPDM, carbon black and oxidation inhibitor are put into mixing equipment by described consumption to mix and obtain Preblend;
2) Preblend step 1) obtained carries out melt blending extruding pelletization with melt extruding equipment, obtains the described polyethylene resin composition being used as gas line warning panel.
In addition, in the course of processing of polyethylene resin composition of the present invention, according to the needs of concrete processing, processing aid conventional in polyvinyl resin processing can be added in blended material.Its consumption is conventional amount used, or adjusts according to the requirement of practical situation.Therefore, in a preferred embodiment of the present invention, add at least one in lubricant, static inhibitor, dispersion agent and pigment at the mixture of described component, then carry out melt blending and obtain described polyethylene resin composition.
In the course of processing of polyethylene resin composition of the present invention, material melts blending temperature is blending temperature used in usual PE Processing, should not only ensureing the complete melting of matrix resin but also can not make to select in its scope of decomposing.In a preferred embodiment of the present invention, described melt blending temperature is 180 ~ 200 DEG C.
In the preparation method of the invention described above, the mixing equipment of material can adopt various mixing equipments used in prior art, as stirrer, kneading machine etc.The melt blending equipment used in aforesaid method of the present invention is the general blending equipment in rubber and plastic processing industry, can be twin screw extruder, the mixing unit of BUSS etc.Preferred twin screw extruder, its rotating speed is generally 200 ~ 450rpm.
Present invention also offers a kind of gas line warning panel, it is made up of described polyethylene resin composition.
Beneficial effect of the present invention:
The polyethylene resin composition of gas line polyethylene warning panel of the present invention can prepare the gas line polyethylene warning panel meeting respective standard and require, comparatively speaking, and cost is controlled, wide material sources.Compared with the mixture of common high density polyethylene(HDPE) and linear low density polyethylene or medium-density polyethylene, anti-punching quality improves a lot
The preparation technology of polyethylene resin composition of the present invention and preparation method thereof is simple, easily applies.
