Problems solved by technology

The traditional preparation process of naphthenic soft rubber toy filling oil is: frequent vacuum distillation of naphthenic crude oil - hydrofining - solvent refining - sulfonation process - white clay supplementary refining. It is difficult to meet the performance requirements of toy filler oil products in terms of exfoliation, yellowing resistance, non-toxic and odorless, and the product yield is low, and the waste clay and acid residue generated in the production process will pollute the environment

Abstract

The invention relates to naphthenic filling oil for soft plastic toys and a preparation method thereof. The preparation method comprises the following steps of: distilling naphthenic crude under the normal and reduced pressure to cut distillate oil of which the acid value is less than 0.5 mgKOH / g and of which the distillation range is between 350 and 500 DEG C; hydrotreating the distillate oil, adding a molecular sieve-containing bifunctional catalyst with active nickel and tungsten components or cobalt and molybdenum components to obtain a hydrogenated component of which the distillation range is between 300 and 400 DEG C, wherein the catalyst takes Al2O3 as a carrier; performing solvent refining on the hydrogenated component to obtain raffinate oil, wherein a solvent ratio is 1:1-2:1, and the extraction temperature is between 45 and 70 DEG C; performing hydrofinishing on the raffinate oil by adopting the refining catalyst which takes a nickel-tungsten or cobalt-molybdenum system as an active component and the Al2O3 as the carrier; and obtaining the naphthenic filling oil with polyaromatic hydrocarbon content less than 0.5 percent, Saybolt color of appearance more than +30 number, the Saybolt color of thermal stability more than +20 number and opening flash point more than 160 DEG C.

Description

technical field [0001] The invention relates to a petroleum-based plasticizer or softening oil and a preparation method thereof, more specifically, to a filler oil for soft rubber toys and a preparation method thereof. Background technique [0002] Thermoplastic elastomers, referred to as TPE / TPR, are based on SEBS and SBS. They are a type of polymer alloy material with general-purpose plastic processing properties, but the product has properties similar to cross-linked rubber. TPE combines the performance of rubber and good processability. Compared with traditional thermosetting rubber, TPE also has the advantages of recyclability, uniform performance of processed products, and easy and accurate size control. As a result, injection-moldable thermoplastic elastomers are gradually replacing traditional rubber in the fields of automobiles, construction, medical devices, packaging, household appliances and consumer goods. [0003] At present, the application and research and d...
