Description
Invention field
The present invention relates to be used for the heat of liquid stablizer of PVC, this stablizer toxic effects, PVC has stabilization to plastifying, and this stabilization is similar to the stabilization that use obtains based on the stablizer of the component that carinogenicity, genotoxicity and mutagenicity (CRM) risk is arranged itself.
The preparation that is used for the heat of liquid stablizer of plastifying PVC must use the Ba salt of the lipophilicity acid compatible with the physicochemical property of PVC and the specific mixture of Zn salt; Said preparation also must can provide fitting lubrication when mixing with PVC, make to come processing PVC by the major technique that fluid or softening PVC contact with the thermometal device of machine (calendering, injection moulding, extrude etc.) that requires commonly used.
The 4-p t butylbenzoic acid is the main ingredient of these preparations.CRM classification (genotoxicity classification: 2) is included in this acid at present.Therefore, this acid and corresponding salt thereof shall not be applied to the thermo-stabilizer preparation, may discharge them because contain the PVC finished product of these chemical substances, cause endangering the huge potential risk of public health.
And the staff's possibility long-term exposure that relates in preparation stablizer and the PVC finished product is in above-mentioned chemical substance, and their health has the risk of being encroached on.
Therefore, there is such industrial requirement in the conventional formulation at the heat of liquid stablizer that is used for PVC, promptly with acid substitution 4-p t butylbenzoic acid safer and that have the proper characteristics that can give similar stability of plasticized PVC and processing characteristics.
Background technology
Be used at present plasticized PVC the heat of liquid stablizer state-of-the-art preparation mainly based on: based on the Ba/Zn of long chain aliphatic carboxylic acid and aromatic carboxylic acid's combination or the mixture of Ca/Zn salt; The organic derivative of phosphorus; And optional high boiling hydrocarbon and softening agent as thinner.In these mixtures, add co-stabilizer and other additive such as antioxidant, lubricant, softening agent, to improve performance.
Aromatic carboxylic acid's existence is very important, can not influence transparency because aromatic carboxylic acid's salt can improve the priming color of PVC preparation in the course of processing.Phenylformic acid is the simplest aromatic carboxylic acid, but because the lipophilicity of its inorganic salt is poor, may bring the problem of separating out (place-out), mainly is in the calendering operation.
On the contrary, the 4-p t butylbenzoic acid has the optimum physical chemical property that satisfies this technical requirements.
United States Patent (USP) the 5th, 880 is mentioned a kind of heat stabilizer composition No. 189, and said composition provides good wettability for the PVC film, and the water color ink that is applied on this film is had good adhesivity.Disclose according to this patent documentation, when Ba/Zn salt is based on C
