Problems solved by technology

When the mold matures, the spores spread in the air and spread everywhere, seriously affecting the quality of storage equipment and the health of warehouse workers
[0003] In the early stage, we used nano-series anti-mildew desiccants in the packaging of equipment, such as: nano-silver silica, nano-chromium silica, and nano-nickel silica. After use, these anti-mildew desiccants have hygroscopic and drying properties. function, but the inhibitory effect on mold within the packaging range is relatively poor. In the case of twice the standard dosage, after two experiments at the peak of mold reproduction, Aspergillus and Trichoderma can still be detected in the microenvironment of sealed packaging , Mucor mold spores, and its spore density still exceeds the mold prevention standard stipulated by the state

Embodiment 1

[0042] The preparation of embodiment 1 anti-mildew function desiccant

[0043]

[0044]

[0045] The preparation method of desiccant 1:

[0046] The first step, the preparation of desiccant base material:

[0047] 1) Put B-type silica gel (pore volume ≥ 0.7ml / g), sulfur rubber, and silicic acid gel in a high-speed pulse melting machine for centrifugal melting. The temperature is kept at 90°C, pH=7.0, and the speed is 30 rpm / Minutes, the time is kept for 70 minutes;

[0048]2) Add nano silicon dioxide, control the temperature at 90°C for 70 minutes at this moment, then quickly drop to 30°C and keep for 70 minutes.

[0049] The second step is the synthesis of desiccant products:

[0050] Add nano-zinc to the prepared solid, organically dissolve at 210°C, pass through a 500-mesh filter sieve for primary screening, and then pass through a 900-mesh filter sieve for re-screening, observe the color change of the liquid, and add benzotriazepam when it becomes transparent az...

Abstract

The invention discloses a drying agent with mildew-proof effect and a preparation method thereof. The drying agent is prepared from the following components by weight: 50-100 parts of deoxidizing agents, 80-150 parts of nanometer mildew inhibitors, 10-90 parts of B-type silica gel, 100-150 parts of benzotriazole, 60-120 parts of C-type silica gel, and 50-90 parts of silicone rubber. In the drying agent formula of the invention, the components support each other and bring out the best in each other; and the drying agent both can control mildew and has significant dehumidifying effect.

Description

technical field [0001] The invention relates to a desiccant with anti-mold function, in particular to the anti-mold desiccant added when storage equipment is sealed and packaged in a humid environment and its preparation method. Background technique [0002] Because aviation equipment must be sealed and packaged when it is stored, and a desiccant must be put into the equipment when it is sealed and packaged to prevent the equipment from being rusted due to humidity during the storage period. However, when the equipment is sealed and packaged, there will be many mold spores in the microenvironment, and the various components of the equipment are various nutrients for the growth of the mold. Therefore, when the conditions are suitable, the mold will grow and reproduce, causing corrosion and mildew of the equipment. There are many kinds of molds that grow in the storage environment, and the growth rate is fast. According to statistics, in the coastal storage environment, the m...
