Abstract
The invention relates to a hard polyethylene pipe with high impact resistance, which solves the problem that the hard PVC pipe has low impact strength, has brittleness, and is easy to leak, permeate and crack. The technical scheme to solve the problem is that: the hard polyethylene pipe is prepared from the following components in part by weight: 220 to 280 parts of PVC, 6 to 10 parts of heat stabilizer, 0.7 to 1.3 parts of lubricant, 2.1 to 2.9 parts of titanium pigment, 10 to 20 parts of impact modifier, 2 to 4 parts of processing aid and 3.5 to 6.5 parts of calcium carbonate; and the hard polyethylene pipe is prepared by the following steps: firstly, evenly mixing the components to prepare a mixture; secondly, heating the mixture to between 105 and 145DEG C, and cooling the mixture to between 30 and 55DEG C; standing the cooled mixture at a normal temperature of between 18 and 25DEG C for 8 to 12h; extruding the mixture at a temperature of between 130 and 220DEG C with an extruder; and cooling at a temperature of between 10 and 22DEG C. The hard polyethylene pipe has good toughness and impact resistance, chemical resistance, and difficult leakage, seepage and crack, and is innovation on pipes.
Description
One, technical field
The present invention relates to tubing, particularly a kind of hard polyethylene pipe with high impact properties.
Two, background technology
From eighties of last century country at the beginning of the eighties in a planned way organize apply chemical building material since, the production of hard PVC tubing and application have obtained the development of advancing by leaps and bounds.An important use of hard PVC tubing is to be used for the water supply and sewerage pipeline engineering construction.As aspect the water network construction, hard PVC tubing has the advantage of long service life than PE tubing, and the theoretical longterm strength of PVC also is higher than longterm strength (PVC 〉=25MPa, the PE 〉=10MPa) of PE.But PVC shows slightly " fragility " with respect to PE, easily injured when being hit, shock strength is lower, cause in its life-time service and be prone to pipe leakage, infiltration is broken, thereby makes the PVC higher tubing of having to adopt when engineering construction, so how improving shock resistance, overcoming " fragility " is the technical problem of necessary solution for the pvc pipe material.
Three, summary of the invention
At above-mentioned situation, for overcoming the defective of prior art, the present invention's purpose just provides a kind of hard polyethylene pipe with high impact properties, it is low effectively to solve hard PVC tubing shock strength, fragility is arranged, be prone to pipe leakage, infiltration, disruptive problem, the technical scheme of its solution is, by by weight: 220～280 parts of PVC, 6～10 parts of thermo-stabilizers, 0.7～1.3 part of lubricant, 2.1～2.9 parts of titanium dioxides, 10～20 parts of impact modifiers, 2～4 parts of processing aids and lime carbonate are made for 3.5～6.5 parts, during preparation, at first said components is mixed, mixture, with mixture heating up to 105～145 ℃, be cooled to 30～55 ℃ again, the refrigerative mixture is after placing 8～12h under normal temperature 18-25 ℃, use forcing machine again under 130～220 ℃ temperature, extrusion moulding is cooled off down at 10～22 ℃ after the extrusion moulding; Said thermo-stabilizer is the thermo-stabilizer lead sulfate tribasic, or the thermo-stabilizer Zinic stearas, or the thermo-stabilizer barium stearate, or organotin stabilizer, or the stablizer of other kind; The polymerization degree of used PVC is 1000～2000; With lubricator be any in lubricant PE wax, lubricant paraffin, the lubricant stearic acid or two kinds, or three kinds mixture; Used impact modifier is any of impact modifier chlorinatedpolyethylene CPE, impact modifier MBS resin (being the terpolymer of methyl methacrylate (M), divinyl (B) and vinylbenzene (S)), impact modifier ethylene-vinyl acetate copolymer EVA or two kinds, or three kinds mixture; Used processing aid is processing aid ACR201 (for the graft copolymer of methyl methacrylate and acrylate), or processing aid ACR401 (being methyl methacrylate, ethyl propenoate, butyl acrylate and four kinds of monomer copolymerizations of vinylbenzene), or processing aid AMS (oligopolymer of alpha-methyl styrene), above-mentioned substance is known commercially available prod.Toughness of the present invention and shock resistance are good, chemical resistance, and antileaking, infiltration is broken, and is the innovation on the tubing.
