Problems solved by technology

The mixed products of organic matter and inorganic matter currently used, on the one hand, due to the inherent insoluble characteristics of the organic matter used, the reaction in water is extremely slow and uneven, so that the toy cannot produce regular ups and downs in water On the other hand, when using hydrophilic organic matter, it often releases a large amount of gas in a short period of time because of its rapid reaction in water, making the toy unable to sink into the water. It does not reach the purpose of making it go up and down and move continuously

Embodiment 1

[0041] Take by weighing raw material (unit: gram) by following weight ratio:

[0042] Fumaric acid 30, sodium carboxymethyl cellulose 5, baking soda 55, polyethylene glycol 5 (m is 3000), magnesium oxide 2, and the balance is essence. The production method is as follows:

[0043] (1). Mix baking soda, magnesium oxide, and essence according to the ratio, and bake at a constant temperature in a thermostat at 140°C for 5 hours;

[0044] (2). Fumaric acid and polyethylene glycol (PEG) were reacted for 12 hours at 80° C. under normal pressure to produce an adduct of fumaric acid and polyethylene glycol (PEG);

[0045] (3). The adduct of fumaric acid and polyethylene glycol (PEG) and sodium carboxymethylcellulose are added to the mixed material obtained in step (1), and uniformly mixed;

[0046] (4). The mixed material is molded into a spherical product under the conditions of 25° C. and humidity of 60%.

Embodiment 2

[0048] Take by weighing raw material (unit: gram) by following weight ratio:

[0049] Fumaric acid 33, sodium carboxymethyl cellulose 4, baking soda 50, polyethylene glycol 10 (m is 4000), magnesium oxide 1, and the balance is essence. The production method is as follows:

[0050] (1). Mix baking soda, magnesium oxide, and essence according to the ratio, and bake in a constant temperature oven at 160°C for 3 hours;

[0051] (2). Reaction of fumaric acid and polyethylene glycol (PEG) at 75°C and normal pressure for 18 hours to produce an adduct of fumaric acid and polyethylene glycol (PEG);

[0052] (3). The adduct of fumaric acid and polyethylene glycol (PEG) and sodium carboxymethylcellulose are added to the mixed material obtained in step (1), and uniformly mixed;

[0053] (4). Forming the mixed material with a tablet machine under the conditions of 30°C and 40% humidity to obtain a sheet-like product of 1.8±0.1g.

Embodiment 3

[0055] Take by weighing raw material (unit: gram) by following weight ratio:

[0056] Fumaric acid 35, carboxymethyl cellulose sodium 3, baking soda 52, polyethylene glycol 7 (m is 4500), magnesium oxide 2, and the balance is essence. The production method is as follows:

[0057] (1). Mix baking soda, magnesium oxide, and essence according to the ratio, and bake in a constant temperature oven at 180°C for 1 hour;

[0058] (2). Reaction of fumaric acid and polyethylene glycol (PEG) at 70°C for 20 hours under normal pressure to produce an adduct of fumaric acid and polyethylene glycol (PEG);

[0059] (3). The adduct of fumaric acid and polyethylene glycol (PEG) and sodium carboxymethylcellulose are added to the mixed material obtained in step (1), and uniformly mixed;

[0060] (4). Forming the mixed material with a tablet machine under the conditions of 38° C. and a humidity of 20% to obtain a sheet product of 1.8±0.1 g.

Abstract

A fumaric acid addition product able to slowly release CO2 gas is prepared from trans-butenedionic acid, carboxymethyl cellulose sodium, soda, polyethylane glycol, and esence. It can be used as the toy which can uniformly and continuous release CO2 gas in water, so it can alternatively be floating on water and sunk in water.

Description

technical field [0001] The invention relates to a slow-release gas product of fumaric acid adduct, its preparation method and its application as a gas release agent in children's toys. Background technique [0002] For catering to children's naturally lively and active characteristics, especially for children's special preference for water, a kind of toy that can be played by children in water has appeared on the market. Add a mixture of organic and inorganic substances to this kind of toy, and use the gas produced by a series of chemical reactions to make the toy float up and down in the water, so as to achieve the purpose of entertainment. The mixed products of organic matter and inorganic matter currently used, on the one hand, due to the inherent insoluble characteristics of the organic matter used, the reaction in water is extremely slow and uneven, so that the toy cannot produce regular ups and downs in water On the other hand, when using hydrophilic organic matter, i...
