Preferably, the processing aid is ACR-401, and the in-lubricant is stearic acid, and the external lubricant is poly- second Alkene wax, the anti-impact toughener is CPE, and the filler is special calcium.
The selection of stabilizer：Polyvinyl chloride resin is primary raw material in the formula of PVC internal layers, and its processing and forming temperature is not generally low In 170 DEG C, so pure polyvinyl chloride resin cannot directly be processed into product.Thus stabilizer is component essential in being formulated. The heat stabilizer that tradition is used is lead salt stabilizer, and representative has tribasic lead sulfate, is commonly called as three salt, and disalt Mafic lead phosphite, is commonly called as disalt.This two kinds of lead salt type thermal stabilizing agent usage histories are most long, and thermostable effect is also preferable, and valency Lattice are cheap.But the substantially unlubricated property of such stabilizer, compatibility and dispersion are poor, and salt chemical substance is Toxic Matter, to human health.For product present invention selection calcium-zinc composite stabilizing agent, the compound stabilizer has thermally-stabilised work With outer, also with the comprehensive function such as lubrication, weather-proof, and consumption is significantly less than lead salt type thermal stabilizing agent.
In-lubricant, external lubricant are selected：The frictional force of material increases in extrusion simultaneously, excessive internal friction Power can make material, and melt viscosity is deteriorated in process, and product turns yellow, and fragility increases.Profit in must thus being added in formula Lubrication prescription, to reduce intermolecular rubbing action, it is to avoid the decomposition of material is produced because of friction, melt viscosity is improved.The present invention Selection is with the good stearic acid of polyvinyl chloride resin compatibility as the in-lubricant in the product formula.In addition, in process, thing The contacted material tube inner wall of material, and all parts can all produce certain rubbing action and may glue it in former It is attached, meanwhile, excessive frictional heat promotes the decomposition reaction of material.In order to reduce the rubbing action of this class, should add in formula Enter external lubricant Tissuemat E.In order to be able to the frictional heat for making PVC material be produced in whole process is more reasonable, it is necessary to while Ratio using inside and outside two kinds of different lubricants, and inside and outside lubricant is suitable, and usage amount is proper.Because usage amount The performance of the excessive or very few processing and product that can all directly affect PVC material, and suitable inside and outside lubricant proportioning can improve The outward appearance and interior quality of product.
ACR-401（Processing aid）：In production and processing, in order to effectively facilitate gel plasticizing of the material in extrusion, It is essential that high polymer processing auxiliary agent is added in formula, and it can not only reduce processing temperature, can also relax technological temperature Adjustable extent, so as to improve the stability of product quality.Acrylic copolymer is adding used by generally acknowledged processing PVC tubing Work auxiliary agent, wherein ACR are to use most processing aids.Present invention selection addition ACR-401, it is promoting the same of material plasticizing When can also improve the erosion-resisting characteristics of product.
CPE as the product formula anti-impact toughener：Because the product is mainly used in State Grid's Cable Reformation, communication The specific uses such as engineering, the present invention must be modified to PVC material, on the basis of the original premium properties of PVC is kept, overcome Defect in some performances, to reach the use requirement of power cable industry, is mainly carried out from the following aspects to PVC material It is modified：
1st, VC materials have certain toughness, overcome black brittleness；
2nd, temperature, is allowed to certain heat resistance；
3rd, surface resistivity or specific insulation, are allowed to antistatic behaviour.
In order to achieve the above object, the additive for adding people to meet these requirements is needed in formula, these change material The additive of performance is referred to as modifying agent.Fragility is presented when PVC product works at a lower temperature.The physics and chemistry of PVC product Larger difference can be produced with the change of operating temperature.The need in order to be applicable the above, it is feasible method to add modifying agent, can To improve the impact resistance of product, application conditions are met.Anti-impact toughness reinforcings of the CPE as the product formula is added in present invention selection Agent.Because CPE is the chlorizate of polyethylene, the CPE of chlorinty 34%-38% is good with polyvinyl chloride resin compatibility, and its blend is not only With excellent low-temperature impact-resistant toughness, and the good chemical resistance of product, oil resistivity, electrical property and fire retardant can be kept Property.CPE forms netted branch in polyvinyl chloride resin, and a kind of elastomeric network for surrounding its primary particle is formed in PVC matrix, leads to Cross and low temperature impact properties are effectively improved to the energy absorption of bruise.
Colouring agent is selected：Simultaneously for reduces cost, the dimensional stability and raising product during raising Product processing are firm Property, it is necessary that can rationally add a certain amount of filler.Suitable colouring agent is selected as requested, and this is in formula It is essential.
A kind of preparation technology of high-strength composite power pipe, including internal layer and outer layer making, internal layer manufacturing process steps It is as follows：
