Description
Technical field
The present invention relates to a kind of PVC thermo-stabilizer, relate in particular to a kind of pvc pipe material, pipe fitting liquid composite stabilizing agent and application thereof.
Background technology
The lead salt thermo-stabilizer is disabled in the U.S. and European Union at present, has replaced the lead salt thermo-stabilizer at U.S.'s organo-tin het stabilizer comprehensively, and Europe is then based on calcium/zinc heat stabilizer.In the Asia, because production cost and technical elements, the nations of China and India is still the user of lead salt one package stabilizer maximum.In China, along with the raising of national life level, people are perfect gradually to the growing interest of health problem and corresponding environmental regulation, the lead salt one package stabilizer will be by security higher and cost reasonably, the kind of compliance with environmental protection requirements replaces.Increasingly stringent has also proposed stern challenge to our thermo-stabilizer industry after especially plumbous declaration is prohibited in June, 2009 pipeline special commission issue.Therefore, all stricter requirement is proposed for the environmental protection and the safe handling of tubing, pipe fitting product no matter be home consumption or products export.This is from Chinese chemical industry newspaper report on July 24th, 2009: June 16, China plastic conduit Professional Committee of plastic working TIA is in annual meeting in 2009, having passed through feeds water forbids using the declaration of lead salt thermo-stabilizer with polyvinyl chloride pipeline, indicate that China completely forbids the beginning of using the lead salt thermo-stabilizer in this field.And the issue of this distance former Ministry of Construction on March 18th, 2004 is over and done with more than 5 years about recommend to use the bulletin of non-lead salt thermo-stabilizer in same field.Developed country such as the U.S., Japan has not just used the lead salt thermo-stabilizer as far back as the sixties in last century; The timetable that also has been ranked on the lead salt thermo-stabilizer problem is being used in Europe: forbidding was forbidden the use of forbidding the lead salt thermo-stabilizer in 75%, 2015 year 100% in 25%, 2010 year in 2005.4 family's tissues such as the plastics association in Europe, plastic door-window association, pipe part association, metope association propose the self-discipline pact, require each member enterprise to stop the use of lead salt thermo-stabilizer fully in 2015.Sweden, Holland have forbidden in 2002 that the lead salt thermo-stabilizer is used for drinking water pipeline.Britain forbids that in December, 2003 the lead salt thermo-stabilizer is used for drinking water pipeline.
Follow the plumbous trend of taboo in the world closely, from 2003, China also began to pay close attention to lead salt thermo-stabilizer problem.According to the director Song Shuyan of pipe-line equipment portion of the water supply and drainage association introduction of Chinese cities and towns, tap water once took place and enters and found the lead incident that exceeds standard behind the floor in Beijing, was exactly that pipeline excess inferior is used due to the lead salt thermo-stabilizer.For filling out urbanite water consumption safety in the guarantee city, Beijing and Shanghai City take the lead in having passed through prohibiting plumbous decision in water service pipe.The bulletin of " apply and restriction bans use of technology " of former Ministry of Construction issue in 2004 spells out, and feedwater must be used non-lead salt thermo-stabilizer with polyvinyl chloride pipe.Through effort in 5 years, up to the present, the enterprise of polyvinyl chloride pipeline manufacturing enterprise, the especially standard of China's overwhelming majority brought into use the thermo-stabilizer of non-lead salts.The enterprise that has uses organo-tin het stabilizer, the enterprise that also has calcium zinc or rare earth complex class thermo-stabilizer.Polychloroethylene heat stabilizer just towards low toxicity, nontoxic, pollution-free, compound, direction develops efficiently.
Now equal both at home and abroad emphasis development and application non-toxic stabilizer, organotin is as one of thermo-stabilizer main and outstanding in the PVC processing non-toxic heat stabilizer, application in outlet and domestic high-end profiled material, tubing, pipe fitting are processed in a large number at present, be mainly kinds such as methyl tin and butyl tin, this also is the major impetus that domestic in recent years organotin output increases fast.The organic tin stablizer is one of best thermo-stabilizer of polyvinyl chloride (PVC).The research of organo-tin het stabilizer, existing nearly 60 years history.Abroad, the development of organic tin stablizer is very fast, especially more outstanding with the U.S..The organo-tin compound that can be used as the use of PVC thermo-stabilizer has several thousand kinds at least, but extensively obtains the kind of industry and commodity achievement, and its basic structure is no more than 20 kinds.Organotin has thermostability as the PVC thermo-stabilizer and weathering resistance is good, prevent excellent properties such as initial coloring is good, nothing (low) is malicious, transparent, at the high packing articles of hygienic requirements such as food, medicine, hard, semi-rigid clear sheet, sheet material, soft transparent PVC film, the food grade bottle, in the use of upper hose material etc., it has occupied irreplaceable status.Current, each state all thermo-stabilizers such as development high effect nontoxic, multi-functional, non-heavy metalization, polymer quantification, Compositional type, low costs as basic orientation.Stablizer with other type is compared, the stablizer in the more approaching ideal of the over-all properties of organic tin stablizer.But all organic tin stablizers, tubular construction is not how, and main drawback is that manufacturing cost is more much higher than Pb stabilizer or metallic soap class mixture.And PVC plastics factory is when using, in the mixing process, the evaporation rate of organotin stabilizer will be accelerated, have the organotin volatile matter of some amount this moment, a small amount of organotin and PVC reaction product one organotin prussiate may also can mix. and together emit together with dust, water vapor, make original just bad more because of the environment of the abominable batch mixing workshop section of dust pollution labor condition.Adopt traditional hand-fed, the mixing method of execute-in-place because present most of factories more, rather than the level of automation height, manually participate in few whole mixing material system, so the workman of this workshop section is very easily by dust and toxic gas infringement; In the opposing party's surface and PVC machine-shaping process. at high temperature PVC will decompose. unstable atom in organotin stabilizer and the PVC molecule forms ligand. and in ligand carboxylic acid ester groups and the unsettled chlorine atomic substitutions of organotin. make PVC keep stablizing, produce the organotin muriate simultaneously.The toxicity of this compound is higher than organotin stabilizer itself far away.These organotin muriates at high temperature also can evaporate. bring harm to the site operation personnel.
Organotin is inadequate under China's actual conditions aspect alternative lead salt, because most plastics enterprise adopts traditional lead salt formula system, the PVC-U boardy product of being produced also mostly is white greatly.If be directly changed into the thiol organotin formula system, not only to the surperficial erosion resistance and the coating of screw rod, barrel and crusher have relatively high expectations (also should change sometimes) comprehensively, and because thiol organotin and plumbous sulfide staining, certain link is careless slightly in the processing will cause crossed contamination, it is color patterned to cause tube surfaces ash to occur, and uses after the product fragmentation after polluting and also can bring secondary pollution.Secondly, it is more different that the formulating of recipe of organotin system, technology controlling and process and lead are that formula system has, and decomposition rate is very fast.And the component of other sulfur-bearing such as filler, tinting material react the phenomenon that causes look in plumbous, cadmium stabilizer and prescription.In the polyvinyl chloride prescription of leaded, cadmium stabilizer, add some material later that contain the tin mercaptides used as stabilizers and also this fraud can take place.But change many reasons such as crossed contamination of bringing after the organotin stabilizer system, numerous tubing, pipe fitting enterprise are hung back.Calcium zinc stabilising system is then different, and it is quite similar with prescription, lubrication mechanism and the complete processing of lead salt formula system, is come to follow a well mapped-out plan convenient control by the lead salt conversion.And Ca-Zn composite heat stabilizer is the kind that wherein has most development prospect, calcium zinc heat stabilizer commonly used is nontoxic, cheap, oilness is good, and with the lead salt formula system quite similar aspect prescription, lubrication mechanism and the complete processing, substitute the lead salt stabilizer ratio and be easier to.But zinc soap often causes goods " zinc burning ", thereby thermal stability is relatively poor, and work range is narrow.In the occasion that product properties is had relatively high expectations, the application of zinc soap and zinc-base composite prod has been subjected to certain restriction.
The applicant has applied for that on 06 26th, 2007 the prescription of this patent thermo-stabilizer of a kind of double matching type heat stabilizer (patent No. is 200710069728.X) is: in parts by weight, the organic liquid single component material 5～20 of the organic liquid single component material 40～60 of calcium metal, the organic liquid single component material 5～20 of zinc metal, magnesium metal, the organic liquid single component material 15～40 of barium metal, organic stabilizer 5～20, Synergistic stabilizer 5～8; Wherein said organic stabilizer is diphenyl thiourea or stearyl benzene alkane, described Synergistic stabilizer is the phosphorous acid esters materials, has reasonable recipe, method is easy, to PVC goods Heat stability is good, characteristics such as excellent property, production cost are low are suitable for and apply.
Summary of the invention
