Description
Technical field
The invention belongs to the technical field of the making method of plastic prod.
Background technology
Polyvinyl chloride all has important use in the every aspect of industry, agricultural, transportation and people's daily life.In recent years, China's polyvinyl chloride development is advanced by leaps and bounds, and 2005 annual capacities increase more than 40%, reach more than 900 ten thousand tons; 2006 annual capacities can have been run neck and neck 1,000 ten thousand tons of Gonna breakthroughs with the U.S..
Polyvinyl chloride is a thermo-sensitive material, and under the condition of forming process temperature (about 130-200 ℃), it can degraded, variable color and decomposites hydrogenchloride.So when forming process, must add thermo-stabilizer, could produce smoothly.At present, the rigid polyvinyl chloride (PVC-U) that China manufacturer produces is given, water shoot, polyvinyl chloride plastic door and window profiled material and polyvinyl chloride electrical wire and cable all are to use the very large rare earth lead of toxicity, tribasic lead sulfate and dibasic Lead Phosphite thermo-stabilizer.The workman of plastic molding and processing plant is subjected to the murder by poisoning of dust when producing, the environment around the factory is also polluted.These deleterious lead salt stabilizers and polyvinyl chloride consistency are relatively poor, and poisonous lead salt stabilizer can be separated out from the PVC-U supplying drainage that uses and polyvinyl chloride plastic door and window profiled material and polyvinyl chloride electrical wire and cable, becomes dust from flying aloft, polluted air.If water shoot be embedded in underground, then polluted underground water source and soil.Estimate that the whole nation need use between ten thousand tons of the poisonous lead salt stabilizer 8-10 this year, and will increase 6-8% every year, this equals to have every year tens thousand of tons of lead salt toxic agent to spill to all parts of the country.
After the people sucks lead dust, people's nervous center and each organ are suffered damage, the lighter descends people's intelligence, and severe patient makes the people lose the study and work ability, even threat to life.
It is reported that the mouth of the Zhujiang River one band heavy metal lead deposits more than 8000 ton, near the fishes and shrimps in waters are polluted by lead poisoning, and fish is the enrich body of heavy metal lead, and edible these fishery products are troubling.
Before 3 years, ten kind tealeaves that the West Lake, Hangzhou periphery is produced detect in the Ministry of Health, and all lead content all exceeds standard.This is because due to the lead salt dust that the PVC-U water shoot that this city's dwelling construction is used is separated out.
The outburst of a plurality of countries infects in the Asia in bird flu.Someone thinks that the PVC-U that countries in Asia use gives, vent pipe makes bird be subjected to lead powder with lead salt and poisons as stablizer, influence bird to due to the resistivity reduction of avian influenza virus.Developed countries such as the U.S. use calcium zinc, organotin as the rigid polyvinyl chloride thermo-stabilizer, and poisonous lead stabilizer is eliminated basically, and bird is less in the chance that the U.S. is infected by lead poisoning, so bird flu is little in the chance of U.S.'s outburst.
Some stablizer factory of west, the lead salt stabilizer as German bear board will be eliminated is reduced to 19%-23% to lead content, says so nontoxic or meets the PVC thermo-stabilizer of hygienic requirements, it is promoted to the many countries in Asia, in wherein China is also included within.Reality is misleading and poisons these national people, makes these countries become the selling market of Hesperian source of raw materials and west industrial goods forever.
On April 1st, 2005, Phoenix Satellite TV week the beautiful jade figured woven silk material read the newspaper, in state-owned 50% children ' s lead poisoning, make the intelligence reduction, after 20 years, Chinese's IQ is than American low 5%.That is really going too far! Originally Chinese gene IQ is 105.And American IQ has only 100.Because the U.S. has eliminated poisonous lead salt stabilizer basically, avoided the murder by poisoning of lead salt, and the poisonous salt stabilizing agent of the also a large amount of uses of China, Chinese are subjected to the lead salt evil serious, influence intelligence and normally bring into play.National departments concerned should forbid producing and using lead salt stabilizer, is instant thing.
The world today enters the scientific knowledge cut-throat competition epoch, and how important knowledge has become to modern society, he be economic interests also be the source of military strength.China ' s peaceful rise recovers Chinese Tang's flourishing age, only makes full use of Chinese brains, and can not be subjected to saturnine influence, grasps knowledge and innovation knowledge, just can reach this purpose.
Summary of the invention
The purpose of this invention is to provide serial polyvinyl chloride (PVC) stabilizer, be applied in the igelite production, the murder by poisoning that solves lead salt brings benefit to the people.
The making method of polyvinyl chloride (PVC) stabilizer of the present invention is:
1, with synthetic calcium stearate of dry method and Zinic stearas:
(1) stearic acid mixes with lime, is heated to 150-180 ℃ and reacts, and generates calcium stearate, and its reaction equation is as follows:
(2) stearic acid mixes with zinc oxide, is heated to 130-150 ℃ and reacts, and generates Zinic stearas, and its reaction equation is as follows:
2, calcium stearate zinc and benzoyl stearyl methane, organotin, polyvalent alcohol, compound such as cured, SG-16 inside and outside lubricant agent is undertaken compoundly by different ratios in vain, forms the efficient calcium-zinc composite stabilizing agent of a plurality of models.
The above-mentioned calcium that makes, zinc composite stabilizer series are named as " lining brightness board " calcium, zinc composite stabilizer.
Calcium zinc, calcium zinc-tin one package stabilizer have following characteristic:
1, calcium zinc-tin one package stabilizer has efficient thermostability to PVC, and its thermostability surpasses tribasic lead sulfate, and the consumption of organotin has only the 0.3-0.4% of polyvinyl chloride resin;
2, lubricated and outer lubrication in calcium zinc, calcium zinc-tin one package stabilizer have preferably to PVC generally, does not need to add lubricant again;
3, calcium-zinc composite stabilizing agent and PVC consistency are very good, can reduce processing temperature 10-15 ℃, avoid the thermolysis of thermo-sensitivity polyvinyl chloride resin, can extrude fast, enhance productivity;
4, calcium zinc, calcium zinc-tin one package stabilizer have activation CaCO
3, make CaCO
3Mix mutually with polyvinyl chloride resin better, improve the physical and mechanical properties of PVC goods, also can add number of C aCO more on the other hand
3, reduce PVC goods cost;
5, with the PVC goods of calcium zinc, calcium zinc-tin stablizer than with the PVC goods of poisonous lead salt stabilizer light aging resisting more, tool is difficult for separating out, and makes PVC water shoot outdoor work-ing life above more than 50 years;
6, calcium zinc, the breakthrough of calcium zinc-tin one package stabilizer on price, the calcium zinc-tin one package stabilizer of our development and production can maintain an equal level with deleterious tribasic lead sulfate on price now, and is perhaps more cheap.The cost that is difficult to cross recent decades closes and at a low price poisonous lead salt closes thereby broken through;
7, lining brightness board calcium-zinc composite stabilizing agent-064# and an amount of crosslinked compatilizer combination are used for ABS/PVC alloy stabilising system, obtain more satisfactory perfect effect, improve the thermostability of ABS/PVC polyblend widely, make the big housing of TV set of ABS/PVC alloy injection moulding become a reality, thereby make PVC be converted into this maximum breakthrough of engineering plastics by ordinary resin.
Above-mentioned characteristic can make the producer that produces PVC supplying drainage, PVC plastic door and windows profile afford to use calcium-zinc composite stabilizing agent, builds green production factory, produces environmentfriendly products and becomes a reality.
