Abstract
The invention relates to a formula for producing polyvinyl chloride (PVC) rigid plastic profiled bars. The formula comprises the components by weight: 75-78% of PVC resin, 10-13% of calcium carbonate, 2-4% of stabilizing agent and 8-10% of impact modifier CPE+ACR+ACM-J9. A preferential scheme of the formula comprises 76% of PVC resin, 12% of calcium carbonate, 3% of stabilizing agent and 9% of CPE+ACR+ACM-J9. The formula has the advantages that the raw material cost is greatly lowered and the market competitiveness of products is improved under the conduction that various physical properties are equivalent to those of the prior art.
Description
Technical field
The invention belongs to the plastic material processing industry, particularly a kind of prescription of producing PVC rigid plastics profiled material.
Background technology
In the plastic material processing industry, the processing of PVC rigid plastics and use are very extensive, and its national standard that adopts is GB/T8814-2004 " door, window is with not plasticized polyvinyl chloride (PVC-U) section bar ".But in process of production, following point all can be run into by a lot of manufacturing enterprises:
1, for improving competitive market power, reduction door, window are used the plastic irregular profile production cost, and enterprise of big portion all is the consumption that increases former processing aid lime carbonate.But the requirement that the shock resistance of product is difficult to be up to state standards.
2, the domestic auxiliary agent kind that is used to produce plastics is more; Enterprise is also a lot, and the ability of raw materials quality, the producer that much produces auxiliary agent are not detected by most of at present enterprise that produces plastic material; Because of factors such as cost of material rise and cost of labor cause this increase; Each auxiliary agent manufacturer adds paraffin, Triple Pressed Stearic Acid or calcium powder etc. and reduces cost for obtaining profit in product, thereby causes the enterprise-quality of producing plastic material to be difficult to control.
Summary of the invention
The technical problem that the present invention will solve provides the prescription of a kind of good product quality, production PVC rigid plastics profiled material that cost is low.
A kind of prescription of producing PVC rigid plastics profiled material, the weight percent of this prescription is: 75～78% polyvinyl chloride resin, 10～13% lime carbonate, 2～4% stablizer, 8～10% impact modifying agent CPE+ACR+ACM
-J9
The preferred version of this prescription is: 76% polyvinyl chloride resin, 12% lime carbonate, 3% stablizer, 9% CPE+ACR+ACM
-J9
Adopt prescription of the present invention under each item physicals situation suitable, to greatly reduce raw materials cost, improved the competitiveness of product in market with prior art.
Embodiment
The quality of PVC rigid plastics is mainly by the decision of following four aspects:
(1) prescription: prescription is the assurance of making the high-quality section bar.A good prescription meets the technological standard (GB8814-2004) of national regulation after at first wanting section bar is produced; Next is that the instinct that becomes of raw material and auxiliary agent is born enterprise and market; The 3rd is to have feasible or the favorable manufacturability ability, makes easy-formation easily, and scrap rate is low.These 3 indispensable, is the most important condition that guarantees qualified products.If the unstable bad or defectiveness of section bar prescription raw materials quality unreasonable or that use, it is very difficult that the section bar of being produced will meet national technical standard, and quality product is difficult to guarantee simultaneously.
(2) choose high quality raw material and auxiliary agent: the section bar prescription is made up of tens kinds of former auxiliarys; Good again prescription; If the former auxiliary quality of using is unstable, even have only a kind of raw material defective, the quality that all directly influences section bar by the gross no matter formulating of recipe how good; If raw material and auxiliary agent are unreliable, wherein a kind ofly there is problem also can make section quality influenced or defective even have only.When selecting raw material supply unit, preferentially selected certain scale for use, society is with a high reputation, and the product of the enterprise of certain popularity is arranged, and preferably directly purchases from producer, guarantees raw materials quality.
(3) equipment and mold: equipment comprises batching, mixing equipment, section bar extruding production line equipment and utility appliance, pipeline system etc.
(4) production technique of section bar wants correct: the production technique of section bar comprises work program from the former full scale production process of expecting the section bar finished product, processing parameter, working method main points, precaution or the like.
Present stage, the proportioning raw materials method that is used to produce plastic material is a lot, and impact modifying agent commonly used at present has ACR, CPE, MBS etc.If the impact modifying agent of selecting for use domestic famous big company to produce replaces, quality is relatively stable on the one hand, on the other hand through reasonably combined, mixes the process method of coupling, also can produce the not high plastic material of steady quality, cost.
The technician improves the prescription of producing plastic material in the journey of plastic material grown place, and formula rate is: 75～78% polyvinyl chloride resin, 10～13% lime carbonate, 2～4% stablizer, 8～10% impact modifying agent CPE+ACR+ACM
-J9
In test of many times, the technician finds that when filling a prescription to following ratio each item technical feature and physicals are optimum: 76% polyvinyl chloride resin, 12% lime carbonate, 3% stablizer, 9% impact modifying agent CPE+ACR+ACM
-J9
Impact modifying agent originally commonly used is that the CPE+ACR collocation is used, and accounts for 12% of total raw material ratio, and the present invention adopts CPE+ACR+ACM under the constant situation of other raw material
-J9The combination impact modifying agent accounts for 9% of total raw material ratio, has increased the consumption of processing aid lime carbonate simultaneously, under the suitable situation of physicals, greatly reduces raw materials cost.
Adopt the present invention to fill a prescription and produce PVC rigid plastics section bar, the equipment of use is the two forcing machines of 65 awls.Any prescription all must have supporting processing parameter in plastic material production, and processing parameter of the present invention is: 180 ℃ of district's temperature, 175 ℃ in two districts, 175 ℃ in three districts, 170 ℃ in four districts, 168 ℃ of merging cores.The present invention has also improved the resistance to impact shock of plastic material when reducing production costs.
Under equal physicals situation, the cost synopsis of common prescription and the present invention's prescription is following:
Common prescription and patent formulation cost synopsis (by 1 ton of calculating)
Common prescription and patent formulation physicals synopsis:
