Problems solved by technology

Its disadvantage is that it is difficult to preserve, and the content of effective chlorine dioxide is too low; Chinese patent ZL200910105220.X discloses a method for slow-acting and slow-release chlorine dioxide by controlling the acid activator to be added slowly to the chlorine dioxide matrix. Acid activation, the device is too complicated, the requirements are harsh in the use process, and it is not convenient enough to meet the general household use requirements

Embodiment 1

[0032] Example 1, A slow-release agent for space environment purification, the mass percentage ratio of its components is:

[0033] Solid chlorine dioxide 20%;

[0034] Hygroscopic agent 12%;

[0035] filler 15%;

[0036] Binder 28%;

[0037] Release agent 12%;

[0038] Spice 13%.

[0039] Wherein, the solid chlorine dioxide is chlorite, and the moisture-absorbing agent is ureate, which can achieve a good moisture-absorbing effect in places with air pollution and heavy moisture. The filler is Shuangfei powder, which has a good filling effect and mainly reduces product cost. The binder is a mixture of 50% porous starch and 50% gelatinized starch, and the effect of mixing in such a ratio to achieve bonding is better, and it is mainly used for granulation. Described release agent is stearate, is mainly used for threshing. The spice is a non-reducing solid spice, such as thyme, which mainly plays a synergistic deodorizing effect.

[0040] The main feature of the slow-rele...

Embodiment 2

[0041] Example 2, The difference from Example 1 is: the slow-release agent used for space environment purification in this example, the mass percentage proportioning of each component is:

[0042] Solid chlorine dioxide 20%;

[0043] Hygroscopic agent 22%;

[0044] filler 13%;

[0045] Adhesive 25%;

[0046] Release agent 10%;

[0047] Spice 10%.

[0048] Wherein, the solid chlorine dioxide is a mixture of 22% chlorite, 56% silicate adsorbing chlorine dioxide and 23% chlorine dioxide-containing gel, and the moisture absorbing agent is 40% quicklime and The mixture of 60% calcium chloride has a good moisture absorption effect in places with air pollution and heavy moisture. The filler is a mixture of 45% calcium carbonate and 55% polyethylene glycol, which has a good filling effect. The binder is microcrystalline cellulose.

[0049] Others are the same as in Embodiment 1, and will not be repeated here.

Embodiment 3

[0050] Example 3, The difference from Example 1 is: the slow-release agent used for space environment purification in this example, the mass percentage proportioning of each component is:

[0051] Solid chlorine dioxide 30%;

[0052] Hygroscopic agent 25%;

[0053] Filler 8%;

[0054] Binder 12%;

[0055] Release agent 12%;

[0056] Spice 13%.

[0057]Wherein, the solid chlorine dioxide is a mixture of 52% chlorite and 48% chlorine dioxide-containing gel, and the solid chlorine dioxide is the mixture of chlorite and silicate adsorbing chlorine dioxide. The mixture, the moisture-absorbing agent is a mixture of 37% calcium chloride and 63% ureate, which has achieved a good moisture-absorbing effect in places with air pollution and heavy water vapor. The filler is a mixture of 24% Shuangfei powder, 36% calcium carbonate and 40% polyethylene glycol, which has a good filling effect. The binder was a mixture of 48% microcrystalline cellulose and 52% hydroxyethyl cellulose. ...

Abstract

The invention relates to a controlled-release agent and particularly relates to a controlled-release agent for purifying a spatial environment. The controlled-release agent comprises the following components in percentage by mass: 10-30% of solid chlorine dioxide, 12-25% of moisture absorbent, 8-15% of filling agent, 13-28% of binder, 7-12% of release agent and 5-13% of spices. The controlled-release agent at least has the following beneficial effects that (1) acid activation is not needed, and the controlled-release agent is convenient to use; (2) the condition that the controlled-release agent is prepared while being used is avoided, and the controlled-release agent can be opened in the air after being unpackaged; (3) the controlled-release agent can be used according to actual conditions, and the effective content of chlorine dioxide can be flexibly regulated; (4) the stability of the controlled-release agent is good, and the guarantee period of the controlled-release agent is long; and (5) the required raw materials are wide in source and low in cost, and therefore, the controlled-release agent is suitable for industrial production.

Description

technical field [0001] The invention relates to a sustained-release agent, in particular to a sustained-release agent for space environment purification. Background technique [0002] With the improvement of people's living standards, the problem of indoor air pollution has been paid more and more attention by people. Pollutants of indoor air pollution mainly include bacteria, viruses, formaldehyde, benzene series, halogenated alkanes and other volatile organic compounds. Because the indoor environment is the main place for people's living activities, long-term exposure to these pollutants may cause disease and cause chronic damage to the respiratory tract, central nervous system, and heart muscle. At the same time, a considerable part of these pollutants has strong carcinogenic toxicity. Therefore, indoor air purification is very important for people's healthy life. [0003] As a fourth-generation green fungicide, chlorine dioxide has strong sterilization and disinfection...
