Embodiment 1

[0019] Embodiment 1 (taking calcium metal content 10% as example)

[0020] Add solvent 200KG, fatty acid 366.4KG (of course it can be one or more mixtures of the following products: oleic acid, capric acid, lauric acid, citric acid, tannic acid), fatty alcohol 333.1KG (of course It is one or a mixture of more than one of the following products: ethanol, sorbyl alcohol, triethylene glycol, 2-octanol, lauryl alcohol, terpineol, C 12-18 Fatty alcohol); under the protection of nitrogen, start stirring until the material is uniform, add calcium hydroxide 192.5KG and continue stirring until the material is completely uniform, then turn on carbon dioxide, control the rate of carbon dioxide at 45 liters / hour, keep the temperature above 60 ° C, and react 3-6 After 1 hour, heat up to 150°C and vacuum dehydrate, generally to a level lower than 1%, preferably lower than 0.3% or 0.1%; add an appropriate amount of filter aid, and filter the reactant by suction filtration to obtain light ye...

Embodiment 2

[0022] Embodiment 2 (taking the kind used in the processing of medical latex gloves as example)

[0023] Add successively the overalkaline liquid fatty acid calcium salt 30% that is 12% of the calcium metal content obtained by embodiment 1, the high-purity liquid zinc 12% that the zinc metal content is 15%, epoxidized soybean oil 10%, phosphite 18% , antioxidant (1010) 2.5%, solvent 25%, start stirring and raise the temperature to 95°C and maintain it for half an hour; then add 2.5% β-diketone and continue stirring for half an hour to obtain a heat stabilizer that can be used in the processing of medical latex gloves .

[0024]

[0025] The calcium / zinc heat stabilizer variety obtained in Example 1-2 is used in the processing of medical latex gloves, and the dosage is only more than 0.5% of PVC resin to achieve the heat stabilization effect required for processing. Products with the same metal content can reduce the cost by about 30%, and improve the quality by about 100%....

Abstract

The invention relates to a peralkaline liquid fatty acid calcium salt produced from renewable resource bio-based materials. At present, the fatty acids used in liquid product production in the PVC plastic processing assistant heat stabilizer are basically petroleum products all over the world; and the light metal calcium with the molecular weight of 40 can not be synthesized into the fatty acid calcium salt with the metal content of higher than 10% by the traditional method. The bio-based peralkaline liquid fatty acid calcium salt is prepared by the following steps: reacting monobasic bio-based fatty acid, calcium hydroxide, organic solvent and bio-based fatty alcohol in an inert gas protective atmosphere by a microemulsification technique, and reacting with acidic gas at 60-150 DEG C for 3-6 hours to obtain the high-purity transparent liquid of which the calcium metal content is 6-15%. The bio-based peralkaline liquid fatty acid calcium salt has the advantages of high storage stability, excellent lubricating property and favorable compounding property, and can be compounded with high-purity liquid zinc into an excellent calcium-zinc heat stabilizer.

Description

technical field [0001] The invention relates to a bio-based chemical material, in particular to a bio-based overalkaline liquid fatty acid calcium salt made from a renewable resource bio-based material. Background technique [0002] At present, the fatty acids used in the production of liquid products in the heat stabilizer of PVC plastic processing aids in the world basically still use petroleum products, and as people pay attention to issues such as climate change and the depletion of fossil resources, low-carbon, environmental protection and sustainable economy The development model is increasingly valued by governments all over the world. Converting renewable raw materials into bio-based materials, and then developing various products to obtain environmentally friendly functional materials, which can reduce carbon emissions and alleviate the oil crisis, has become a hot field of global research. [0003] PVC plastics have been involved in all aspects of national industr...
