Method for preparing anti-freezing antioxygen

Abstract

The invention discloses a preparation method of an anticoagulant antioxidant, comprising the following steps: 1) making an aqueous emulsion by high-speed shearing of deionized water and a water-immiscible phase, wherein the water-immiscible phase contains a main antioxidant, an auxiliary Antioxidant and emulsifier; 2) add thickener, antifreeze, anticoagulant, defoamer, flame retardant, flame retardant synergist and toughening agent in described aqueous emulsion; Described each raw material accounts for The total mass ratio of the emulsion-type low particle size high-efficiency antioxidant is: primary antioxidant 5-20%, auxiliary antioxidant 8-40%, emulsifier 2-4%, thickener 0.5-4%, antifreeze 1 ~3%, anticoagulant 6~12%, defoamer 1~8%, flame retardant 3~7%, flame retardant synergist 4~9%, toughening agent 2~8%, the rest is deionized Water; the present invention has the following positive effects: using environmental brominated flame retardants such as decabromodiphenylethane, brominated triazine, brominated epoxy, tetrabromobisphenol A to replace polybrominated biphenyls and polybrominated diphenyl ethers, very environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of antioxidant production, in particular to a preparation method of an anticoagulant antioxidant. Background technique [0002] Rubber, plastic, ABS, latex, etc. are important materials in daily life, and their application fields are constantly expanding. However, whether natural or synthetic, polymer materials are prone to oxidation reactions, which will cause the materials to fade, yellow, harden, and rot. Cracking, loss of luster and transparency, etc., which will lead to the reduction of physical properties such as impact strength, bending strength, tensile strength and elongation, which will affect the use. So adding antioxidants to these materials is the simplest and most effective method. The original amine antioxidants have been used as general-purpose antioxidants for rubber for many years, but their application in light-colored and high-end products is limited due to their pollution to the environ...
