Abstract

The invention discloses foaming masterbatch and a preparation method thereof. The foaming masterbatch is prepared from the following raw materials in percentage: 65 to 70 percent of modified nano powder, 20 to 29 percent of carrier resin, 5 to 10 percent of cycloparaffin rubber filling oil, 0.2 to 0.4 percent of a sodium bicarbonate foaming agent, 0.2 to 0.4 percent of a flame retardant, 0.2 to 0.4 percent of a calcium stearate heat stabilizer, 0.2 to 0.4 percent of a polyethylene wax dispersant, 0.1 to 0.3 percent of a beta nucleating agent , 0.1 to 0.3 percent of an antioxidant, 0.1 to 0.3 percent of a titanate coupling agent, 0.1 to 0.3 percent of an ionic type Gemini surfactant and 0 to 0.5 percent of a UV-P ultraviolet light absorber. The preparation method of the foaming masterbatchcomprises the following steps: S1, weighing; S2, preparing inorganic nano powder; S3, preparing; S4, stirring; S5, sterilizing; S6, extruding a finished product. According to the preparation method disclosed by the invention, by adding the flame retardant into raw materials for preparing the foaming masterbatch, the flame retardant performance of the foaming masterbatch can be improved and the inherent excellent performance of original materials is not changed; in addition, the foaming masterbatch has small toxicity and low cost.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a foam masterbatch and a preparation method thereof. Background technique [0002] Masterbatch, composed of excess chemical additives, carrier resin and dispersant. Masterbatch is an aggregate obtained by uniformly loading a super-normal amount of chemical additives in the resin. Commonly used masterbatches are divided into cooling masterbatches, brightening masterbatches, moisture-absorbing defoaming masterbatches, flame-retardant masterbatches and foaming masterbatches. Foaming masterbatch is an endothermic closed-cell chemical nucleating foaming agent. [0003] The Chinese invention patent with the notification number CN104817774A discloses a foam masterbatch and its preparation method. The foam masterbatch prepared by the invention has good dispersibility and excellent processing performance. It can be used in the foaming process of EVA, LDPE and TPR shoe materials Adding...
