[0005] The patent document with the application number 201310719422.X introduces the addition of 0.01 to 1.0% toner to the composite antioxidant, and the patent document with the application number 201610705396.9 introduces the compounding of two main antioxidants and one auxiliary antioxidant The process introduced in the patent document with application number 201410559265.5 uses phenolic primary antioxidants, sulfur-containing or phosphite secondary antioxidants and lubricants as raw materials for compounding. poor improvement
[0006] In addition, U.S. Patent US 4443585 introduced a small amount of fourth-component monomers such as butyl acrylate and butyl methacrylate to replace part of butadiene during the polymerization of styrene-butadiene to improve the heat resistance of MBS. The improvement effect is also limited, and the overall cost of the product is relatively high
[0007] In addition, patents for compound stabilizers containing stearic acid stabilizers, organotin, antioxidants, long-chain alcohols and esters used in PVC processing, such as patents with application numbers 201410770932.4, 201110190646.7, 201310014732.1, 201310040221.7 and 201610521747.0 None of the files are suitable for post-processing such as MBS coagulation, which not only affects the transparency of MBS resin, but also does not benefit the improvement of resin color and heat resistance

Embodiment 1～10

[0048] As shown in Table 1, after weighing each component of the emulsion in the embodiment according to the preparation formula, dissolve it with a solvent, and then mix it with the aqueous solution of the emulsifier. After mixing evenly, turn on the colloid mill or homogenizer, and pour the mixture solution into it at the same time, emulsify evenly and then unload.

[0049] At room temperature and stirring, add 0.5% of the dry solids of the above-mentioned emulsion into the MBS latex, mix well, add sulfuric acid aqueous solution at a certain temperature to break the emulsion, and then raise the temperature to the curing temperature to cure the MBS resin. Finally, the MBS resin was obtained by centrifugal drying. Visually inspect the whiteness, then measure the static thermal stability in a thermostat at 180°C, and measure the dynamic thermal stability on a double-roll mill at 180°C.

Abstract

The invention relates to an emulsion composition for improving the color of MBS resin powder. The emulsion composition comprises oil-phase components and water-phase components, wherein the oil-phase components comprise an antioxidant, an ultraviolet absorber, a heat stabilizer, a fluorescent brightener and an organic solvent, and the water-phase components comprise an emulsifier and water. When the emulsion composition is used, homogeneous emulsion dispersion is prepared by using a high-speed mechanical mixing manner, and the emulsion composition is added to an MBS resin emulsion in a coagulation process, so that the initial color and heat resistance of resin can be greatly improved. The emulsion composition presents complementary and synergistic effects of different aids for improving the same physical property of MBS resin, and has an excellent using effect.

Description

technical field [0001] The invention belongs to the field of polymer compounds, and relates to an emulsion composition for improving the color and heat resistance of methyl methacrylate-butadiene-styrene (MBS) resin powder, and an emulsion containing the emulsion prepared by using the emulsion composition Dry solids MBS resin mixture. Background technique [0002] MBS resin is a transparent impact modifier for polyvinyl chloride. It can greatly improve the impact resistance of products without compromising the excellent transparency of PVC, and at the same time improve the cold resistance and processing fluidity of products. Since MBS is a typical multi-component graft copolymer with a core-shell structure, the core layer contains butadiene components, rich in a large number of double bonds, and its aging resistance is inherently insufficient. In addition, due to the influence of the particle size of the base latex and the uniformity of the core-shell wrapping during the po...
