Embodiment 1

[0023] The present invention proposes a method for preparing a stabilizer for synthetic rubber, comprising the steps of: taking a 500ml beaker, mixing 45g resin, 15g sodium polyacrylate, 7g polymer compound fat, 13g sodium linoleate, 7g sodium stearate, Mix 3g of hydrotalcite powder and 4g of muscovite powder, heat it, heat it at 85°C for 3min, and cut it with a high-speed shear for 3min at a speed of 1250 rpm. Add 6g of additives to it at a constant temperature, the plasticizer in the additive is dioctyl phthalate o, the blowing agent is hydrogenated chlorofluorocarbon blowing agent, and the crosslinking agent is dicumyl peroxide , the accelerator is dibenzothiazole disulfide, the antioxidant is butyl hydroxyanisole, and then it is stirred for 3 minutes, and naturally cooled to room temperature to obtain an emulsion-like stabilizer. Test results: the average particle size is 1.32μm, and the viscosity is 870CPS.

Abstract

The invention relates to the technical field of preparation methods for synthetic rubber additives, and discloses a stabilizer for synthetic rubber. The stabilizer, with the total mass of 100%, is prepared from the following raw materials in parts by weight: 40-50% of resin, 10-20% of sodium polyacrylate, 5-10% of high-molecular complex liped, 10-15% of sodium linoleate, 5-10% of sodium stearate,3-5% of hydrotalcite powder, 4-6% of white mica powder and the balance an additive, wherein the additive, with the total weight of 100 g, is prepared from the following raw materials in parts by weight: 40 g of a plasticizer, 20 g of a foaming agent, 10 g of a cross-linking agent, 15 g of an accelerant and 15 g of an antioxidant, the plasticizer is any one of dioctyl phthalate I and dioctyl phthalate II, the foaming agent is any one of a hydrogenated chlorofluorocarbon foaming agent I and a hydrogenated chlorofluorocarbon foaming agent II, and the cross-linking agent is any one of dicumyl peroxide and di-tert-butyl peroxide. The stabilizer for the synthetic rubber has the advantage that the problems that synthetic rubber is large in toxicity and easy to volatilize in the existing syntheticrubber production process can be solved.

Description

technical field [0001] The invention relates to the technical field of preparation methods of synthetic rubber additives, in particular to a synthetic rubber stabilizer and a preparation method thereof. Background technique [0002] Generally speaking, rubber stabilizer generally refers to the vulcanization catalyst of rubber. Because natural rubber is soft and difficult to be molded and used, it needs to be vulcanized or plasticized. The role of this stabilizer is to promote rubber vulcanization and increase The degree of vulcanization, PVC resin is a polar non-crystalline high polymer, there is a strong force between molecules, it is a hard and brittle material. PVC resin (PVC) is one of the important organic synthetic materials. English name: Polyvinyl Chloride, chemical structural formula: (CH2-CHCL)n, its products have good physical and chemical properties, and are widely used in industry, construction, agriculture, daily life, packaging, electric power, public utiliti...
