Abstract
A leadfree organic silicon and organic boron thermal stabilizing agent for polyethylene is prepared from oxides containing silicone, boron or carbon, etc. as raw materials, by etherifying, esterifying and acidating to organic silicone, boron or carbon oligopolymers with inorganic elements as cores and regular molecular chains to be no metal contained thermal stabilizing agents with better performance than lead thermal stabilizing agents. It is produced with low cost and without wastes in production and toxicity in use.
Description
One. technical field
The invention belongs to chemical field, say that at length relating to a kind of is raw material with organic compound such as silicon, boron, carbon oxides or oxygenatedchemicals, Fatty Alcohol(C12-C14 and C12-C18), lipid acid, acid anhydrides, aliphatic amides, prepares the method for unleaded organosilicon, organic boron polychloroethylene heat stabilizer.
Two. background technology
As everyone knows, because the molecular defect in the PVC molecular chain is very easily deviate from hydrogenchloride and weather stain in the course of processing, therefore, thermo-stabilizer is exactly a most important auxiliary agent in the PVC processing.Up to now, in the boardy product of PVC, main stablizer is various lead salts and compound lead, though Pb stabilizer Heat stability is good, but the toxicity of lead salt is well-known, along with the raising of environmental consciousness, and the market that lead salt will seriously influence it to the pollution and the toxicity of environment.In the soft goods and transparent article of PVC, based on organic tin, liquid barium, cadmium, zinc class and phosphorous acid lipid, these kinds, though in the less application of the toxicity that has extremely strong pungent odour is arranged, contaminate environment, and cost is all very high.Use separately, its thermostability also is difficult to satisfy the requirement of PVC processing.In addition, the rare earth class stablizer that grew up in recent years also has certain market, but rare-earth products production cost height, thermostability is not high can not be used separately, must use with stablizers such as lead salt, cadmium class, zinc class are collaborative, also makes it be subjected to certain restriction.
Three. summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, proposed new technical scheme.
The present invention realizes by following technical measures:
The preparation method of a kind of unleaded organosilicon, organic boron polychloroethylene heat stabilizer; it is with silicon, boron, carbon oxides or oxygenatedchemicals and the organic alcohol that should measure in contrast, organic acid, polyvalent alcohol, polyprotonic acid, nitrogenous compound and senior fat or aromatic alcohol, acid or amine are that raw material adds a little catalyzer again through etherificate, esterification, acylation reaction; prepare with the inorganic elements is core; the oligopolymer of the regular organosilicon of molecular chain, boron, carbon is not contain any metal or oligometallic novel thermo-stabilizer.According to the requirement of product properties, this product also can add a spot of coupling agent, softening agent and auxiliary stabilizer, as silane, aluminic acid lipoprotein, metatitanic acid fat, phosphorous acid ester, epoxy soybean wet goods, is re-dubbed the thermo-stabilizer of polyvinyl chloride excellent performance.Silicon, boron, oxycarbide or oxygenatedchemicals can singlely use, and also can mix use.Unleaded organosilicon, organic boron polychloroethylene heat stabilizer can be the products of step etherificate or an esterification, also the product that can form through the etherificate more than two steps or esterification.
Above-mentioned progressively etherificate, esterification, acylation reaction are proceed step by step, and the temperature of the first step etherification reaction is 100-200 ℃, 1-3 hour; the second step esterification reaction temperature is 150-200 ℃; 2-3 hour, the esterification reaction temperature in the 3rd, the 4th step was 160-230 ℃, 2-3 hour.
Above-mentioned organic alcohol is methyl alcohol, ethanol, propyl alcohol, butanols, octanol, nonyl alcohol, certain herbaceous plants with big flowers alcohol, lauryl alcohol, hexadecanol, stearyl alcohol, ethylene glycol, propylene glycol, butyleneglycol, hexylene glycol, ethohexadiol, certain herbaceous plants with big flowers glycol, diethanolamine, glycerol, trihydroxytoluene, trolamine, organic acid is butyric acid, caproic acid, sad, Succinic Acid, hexanodioic acid, phthalic acid, laurostearic acid, oleic acid, stearic acid, and acid anhydrides has phthalic anhydride, along the rare dianhydride of fourth.Organic pure and mild organic acid can singlely use, and also can mix use.
PVC thermo-stabilizer of the present invention and lead salt and other existing thermo-stabilizers are compared has following advantage:
1. excellent product performance, its thermostability is more than 1.2 times of lead salt and complex lead salt.Can replace lead salt, be applied to boardy product, the particularly application on plastic-steel door and window profiled material, tubing, sheet material, its stability has has all met or exceeded the performance of Pb stabilizer, but equivalent substitution organic tin in transparent article, nontoxic goods and soft goods, main performance index all meets or exceeds the organic tin product.
2. the polrvinyl chloride product production cost is reduced, use product of the present invention, can make its material cost per ton reduce 100-600 unit according to different PVC.
3. Heat stability is good, because the molecular symmetry and the conjugacy of this product, this product has the thermostability and the UV resistant performance of excellent main chain protection mechanism.
4. this product has a plurality of ester bonds, ehter bond and amine key and phenyl ring, contains the long-chain fat key again, therefore has excellent inside and outside oilness.
5. this product had both contained inorganic transition element, silicon, boron, carbon have affinity to inorganic elements, contain aliphatic chain again, so this product and coupling with excellence, be engaged in epoxy soybean oil, silane series coupling agent etc. and use in the boardy product, can strengthen the addition of lime carbonate, reduce cost, and guarantee that the every index of goods does not reduce.
6. this product facility less investment, production cost are low, the economic benefit height.
7. this product is a feature of environmental protection Chemicals, does not only have the three wastes in the process of producing product, and is also nontoxic dustless in the product application process.
Four. embodiment
Example 1
In reactor, add 80 kilograms of boric acid, 20 kilograms of silicic acid add the trolamine that measures, and add a small amount of vitriol oil, and at 120-180 ℃ of dehydration reaction 1-3 hour, step of reaction was not stopped carbonating gas.Be cooled to below 150 ℃, add the hexanodioic acid of metering, under 150-190 ℃, reacted 2-3 hour, drip a little phosphoric acid, add the ethohexadiol of metering again, 160-200 ℃ of reaction 2-3 hour, the stearic acid that adds metering after the dehydration again, at 160-230 ℃ of dehydration reaction 2-3 hour, cooling, the silane coupling agent of adding about 5%, promptly get 1650 kilograms of products, product yield is more than 98%.
