Technical Field

The invention relates to the field of heat stabilizers, in particular to an environment-friendly composite heat stabilizer composition and application thereof.

Background

In recent years, with the development of modern science and technology, high polymer materials are more and more favored by people, and the PVC resin is widely applied to the fields of buildings, agriculture and living goods due to simple processing technology and low price. The biggest defect of PVC is poor thermal stability, dehydrochlorination degradation reaction is easy to occur at a lower temperature (100-200 ℃), hydrogen chloride is quickly lost at 200 ℃, so that a polymer becomes dark color, the strength is low, and the application of the PVC is seriously influenced. Therefore, heat stabilizers must be added during PVC processing.

The PVC plastic heat stabilizer has been developed for decades and passes through several generations of products, the lead salt stabilizer is the earliest product, has the best heat stability and the most mature production and application technology, the toxicity of heavy metal lead is the fatal defect of the lead salt stabilizer, the lead salt stabilizer has higher and higher requirements on the environment along with the development of industry and society, and the lead salt heat stabilizer is rarely used in developed countries such as Europe and America and replaces the nontoxic calcium-zinc composite heat stabilizer. The lead salt stabilizer is still used in large quantity in China, but the problems of environmental pollution, public nuisance and the like caused by the lead salt stabilizer are paid attention by relevant departments, and the non-toxicity and environmental protection of the PVC heat stabilizer are also in great tendency. In recent years, a large amount of nontoxic heat stabilizers are also put into research, development, production, application and other works in China.

Although various preparation methods of composite heat stabilizers exist, the prepared heat stabilizer has strict requirements on the reaction process, or the current heat stabilizer cannot meet the trend of no toxicity and environmental protection. Or it is expensive, high cost, and has peculiar smell; the initial thermal stability and the long-term thermal stability cannot be obviously improved, the application is wide, and the phenomenon of zinc burning is easy to occur.

In a more preferred embodiment of the present invention, the R1 is a C1 to C12 alkyl group; r2 is C1-C8 alkylene, R3 is C5-C20 alkyl; x and y are independently any integer from 1 to 3.

In a more preferred embodiment of the invention, the organotin is an alkylthioalkanoate of a mono-or dialkyltin corresponding to formula (I). In the screening of R1 above, compounds conforming to formula (I) suitable for the present invention include, but are not limited to, monomethyl tin tris (2-ethylhexyl thioglycolate), dimethyl tin bis (2-ethylhexyl thioglycolate), monobutyl tin tris (2-ethylhexyl thioglycolate), dibutyl tin bis (2-ethylhexyl thioglycolate), monooctyl tin tris (2-ethylhexyl thioglycolate) and dioctyl tin bis (2-ethylhexyl thioglycolate), dibutyl tin bis (isooctylthioglycolate), isooctyldimethyl tin dithioacetate.

In a more preferred embodiment of the invention, the alkylthioalkanoates of mono-or dialkyltin corresponding to the above general formula (I) comprise (A) isooctyldimethyltin dithioacetate and (B) dibutyltin di (isooctylmercaptoacetate).

It has been unexpectedly found that when a compound of the above formula is used, the initial photostability is higher than that of other non-preferred components, and especially, the effect is best when dibutyltin di (isooctylmercaptoacetate) or isooctyldimethyltin dithioacetate is used in combination; the inventor conjectures that the former has a multi-carbonyl structure which can coordinate with zinc to replace chlorine atoms on a plastic molecular chain, when the former acts alone, the coordination bond and the product stability are not good, and the light stability is not good, and when the former acts synergistically with the latter, the coordination of the multi-carbonyl structure and the zinc is enhanced due to the steric hindrance of an alkyl substituent, so that the two synergistically have long-term stability to light.

In a more preferred embodiment of the invention, the organotin has a tin content of greater than or equal to 17.0% and a color number of less than or equal to 150 #.

The chromaticity is the chromaticity (Pt-Co number), the chromaticity (Pt-Co number) is the measurement according to the platinum-cobalt (Pt-Co) colorimetric method adopted by GB/T605-2006 general method for measuring chromaticity of chemical reagents, namely the Hazen method, the chromaticity number is 0-30 which is colorless, 30-60 which is slightly colored and almost invisible, and 60-100 which is slightly yellowish.

The research shows that the effect is remarkable when the two-component organotin is adopted, especially when the chroma of (A) and (B) is less than 150#, and the tin content in (A) is more than or equal to 17.0 percent, the light stability is best, and the mass ratio of (A) to (B) is 2: 1, the change of the delta E value is not large, the delta E value is greatly changed along with the increase of the relative content of the component (B), when only the component (B) exists, the light stability of the system is the worst, so that the fact that the component (A) and the component (B) can generate a certain synergistic effect under the coexistence of the two components can be inferred, the addition of the component (B) is favorable for improving the light stability of the component (A), and the research on different components (B) also shows that the problem of photo-thermal instability of the system can be effectively solved by adopting the proper component (B), so that the excellent composite heat stabilizer disclosed by the invention is obtained.

(b) C8-30 long-chain alkyl thioester or thiol

In a more preferred embodiment of the present invention, the C8-30 long-chain alkyl thioester or thiol is selected from one or more of n-dodecyl mercaptan, t-dodecyl mercaptan, octyl decyl mercaptan, tetradecyl mercaptan, hexadecyl mercaptan, butyl thioglycolate, isooctyl thioglycolate, dodecyl thioglycolate, butane mercaptan, decane mercaptan, dodecane mercaptan, 1-hexadecane mercaptan, nonane mercaptan, octadecane mercaptan, tetradecane mercaptan, tridecane mercaptan, undecane mercaptan, 2, 4-dimethylphenylthiol, 2, 5-dimethylphenylthiol, perfluorodecane mercaptan, 1-naphthalene mercaptan, and 2, 4-di-t-butylthiophenol.

In a more preferred embodiment of the invention, the C8-30 long-chain alkyl thioester or thiol is isooctyl thioglycolate.

The inventors have further studied about two-component organotins and found that, particularly when the mass ratio of (A) to (B) is 2: 1, the light stability is best, therefore, it is supposed that although the complexation is weaker when the component (A) exists alone, the complexation and the component (B) can be mutually complemented together, meanwhile, in consideration of the compatibility, isooctyl thioglycolate is added into the system, the initial light stability is better, the metal aggregate formed by promoting double-component organic tin and metal impurities on polyvinyl chloride in the system, which may be isooctyl thioglycolate, plays a certain role in stabilizing, and the conjugated structure of mercaptan is destroyed after the mercaptan reacts with unsaturated bonds of polyvinyl chloride, so that the color of the product is weakened by partitioning the plastic molecular chain into a plurality of chain links which do not meet the color development condition.
