Problems solved by technology

[0004] In order to solve the problem of formamide in children's floor mats, domestic EVA foam manufacturers have studied the use of a new foaming agent OBSH (4,4-oxobisbenzenesulfonyl hydrazide) to replace AC, but many indicators of the properties of the products produced It cannot be compared with the foamed products produced by the existing AC foaming agent
Moreover, OBSH foaming agent is much more expensive than AC, and the finished product still has formamide residue.

Embodiment 1

[0026] Embodiment 1 The preparation of ammonia removal agent

[0027] (1) Add 1kg sodium stearate, 1kg stearic acid and 35kg white oil into the container and stir;

[0028] (2) Add 60kg of anhydrous aluminum sulfate in the stirring process until it dissolves into a uniform paste to obtain the ammonia removal agent, which is then packaged.

Embodiment 2

[0029] Embodiment 2 Preparation of ammonia removal agent

[0030] (1) Add 1.5kg sodium stearate, 1kg stearic acid and 37kg white oil into the container, stir;

[0031] (2) Add 65 kg of anhydrous aluminum sulfate in the stirring process until it dissolves into a uniform paste to obtain the ammonia removal agent and pack it separately.

Embodiment 3

[0032] Embodiment 3 The preparation of ammonia removal agent predispersed masterbatch

[0033] (1) Add 1kg sodium stearate, 1kg stearic acid and 35kg white oil into the container and stir;

[0034] (2) add 60kg of anhydrous aluminum sulfate again in stirring process, until dissolving becomes uniform paste, obtains ammonia agent;

[0035] (3) Mix the obtained ammonia removal agent with EVA at a mass ratio of 3:1, put them into an internal mixer and banbury until both are melted and evenly dispersed together;

[0036] (4) Put the mixed dough into a plastic granulator for granulation, and cool to obtain the pre-dispersed masterbatch of ammonia removal agent.

Abstract

The invention discloses an ammonia removal agent used for a rubber and plastic foaming product and a preparation method thereof. The ammonia removal agent comprises, by weight, 60-65 parts of anhydrous aluminum sulfate, 2-3 parts of surface modification agents and 32-37 parts of solvent. The method includes the steps that the surface modification agents and the solvent are added into a container according to the proportion and then stirred; in the stirring process, the anhydrous aluminum sulfate is added to be dissolved into even paste, so that the ammonia removal agent is obtained. The ammonia removal agent is added into EVA and can rapidly disperse and react with ammonia radicals, in this way, the ammonia radicals and ammonia are effectively removed, and conditions for forming formamide can be broken before the formamide is formed.

Description

technical field [0001] The invention relates to a deamination agent for removing the irritating ammonia smell and toxic formamide produced when the AC foaming agent is decomposed in the rubber and plastic foaming industry, a deamination agent pre-dispersed masterbatch and a preparation method thereof, belonging to rubber and plastics field of processing technology. Background technique [0002] At present, the application of rubber foam, plastic foam, and rubber-plastic blended foam is more and more extensive. Ethylene-vinyl acetate copolymer (EVA) cross-linked foaming material has the characteristics of low density, good physical properties, and good weather resistance. It has developed rapidly in recent years and is widely used in sports equipment, mattresses, children's floors, life-saving products, high-end sports Manufacture of shoes etc. Especially brightly colored children's floor mats can be seen in many families with children, including children's play areas in ki...
