Abstract

The invention discloses a mercaptoethyl dioleate dimethoxycarbonylethyl tin compound. The molecular formula of the compound is shown in the description. Oleic acid is used to synthesize a (reverse) ester tin compound, the change of the (reverse) ester group increases the activity of the (reverse) ester group and realizes good early-stage stability when the (reverse) ester tin compound is used as a stabilizer, and high-molecular-weight oleic acid in the ester makes the compound have excellent lubricity and have the effects not possessed by traditional organic tin. A unique device and a unique technology are adopted, so the reaction effect is good, the efficiency is high, and the application prospect is good.

Description

Technical field: [0001] The invention relates to a Youji tin compound and a preparation method thereof, more particularly, to a dimethoxycarbonyl ethyl tin compound of mercaptoethyl alcohol dioleate and a preparation method thereof. Background technique: [0002] At present, when vinyl halide resins and compositions containing vinyl halide resins are converted into products, the products are formed by thermoforming by heating and softening or melting the resins, that is, converting the powdery resin composition into a molten substance, and then Extruded to desired shape. During this process heat is generated by the friction that occurs within the compound, and the heat required to soften the vinyl halide resin composition varies with the composition, but is generally between 165-210°C. Vinyl halide resin will be degraded under the condition of higher than 100°C, and the degradation will lead to discoloration and loss of physical properties of vinyl halide resin, and even be...
